Landscape‐scale impacts of Cyclone Larry on the forests of northeast Australia,including comparisons with previous cyclones impacting the region between 1858 and 2006

Abstract Cyclone Larry (category 4) was the most severe cyclone to impact on the Wet Tropics bioregion since the devastating 1918 Innisfail cyclone. Based on an analysis of earlier cyclones impacting on this region over the period 1856–2006, it was determined that Larry was a ‘1 in 50 year’ event. This paper provides an overview of the landscape‐scale impacts of Larry on the forest ecosystems of the Wet Tropics region, based on low‐level helicopter surveys 2 weeks after the event. Cyclone Larry has been described as a ‘midget’ cyclone. Severe forest damage only extended about 30 km from the central track of the cyclone while moderate to severe damage extended some 50 km. Moderate to slight canopy disturbance was rarely identified more than 75 km from the centre of the cyclone's track. Beyond 75 km, forest damage was restricted to exposed areas of elevated terrain and in places exposed to strong lee (gravity) waves from the west. The ecological role of cyclones as important disturbance agents affecting the structure and function of forest ecosystems in the region is discussed, followed by an evaluation of likely effects of climate change on cyclone frequency and intensity.     

Amphidromy links a newly documented fish community of continental Australian streams, to oceanic islands of the west Pacific

Background

Indo-Pacific high island streams experience extreme hydrological variation, and are characterised by freshwater fish species with an amphidromous life history. Amphidromy is a likely adaptation for colonisation of island streams following stochastic events that lead to local extirpation. In the Wet Tropics of north-eastern Australia, steep coastal mountain streams share similar physical characteristics to island systems. These streams are poorly surveyed, but may provide suitable habitat for amphidromous species. However, due to their ephemeral nature, common non-diadromous freshwater species of continental Australia are unlikely to persist. Consequently, we hypothesise that coastal Wet Tropics streams are faunally more similar, to distant Pacific island communities, than to nearby faunas of large continental rivers.

Methods/Principal Findings

Surveys of coastal Wet Tropics streams recorded 26 species, 10 of which are first records for Australia, with three species undescribed. This fish community is unique in an Australian context in that it contains mostly amphidromous species, including sicydiine gobies of the genera Sicyopterus, Sicyopus, Smilosicyopus and Stiphodon. Species presence/absence data of coastal Wet Tropics streams were compared to both Wet Tropics river networks and Pacific island faunas. ANOSIM indicated the fish fauna of north-eastern Australian coastal streams were more similar to distant Pacific islands (R = 0.76), than to nearby continental rivers (R = 0.98).

Main Conclusions/Significance

Coastal Wet Tropics streams are faunally more similar to distant Pacific islands (79% of species shared), than to nearby continental fauna due to two factors. First, coastal Wet Tropics streams lack many non-diadromous freshwater fish which are common in nearby large rivers. Second, many amphidromous species found in coastal Wet Tropics streams and Indo-Pacific islands remain absent from large rivers of the Wet Tropics. The evolutionary and conservation significance of this newly discovered Australian fauna requires clarification in the context of the wider amphidromous fish community of the Pacific.     

Does biogeographical history matter? Diversity and distribution of lotic midges (Diptera: Chironomidae) in the Australian Wet Tropics

Abstract We examined broad scale patterns of diversity and distribution of lotic Chironomidae (Diptera) within the Wet Tropics bioregion of northern Queensland, Australia. Field surveys across broad latitudinal and altitudinal gradients within the Wet Tropics revealed a fauna of 87 species‐level taxa in 49 genera comprising three main elements: a small genuinely tropical fraction, and larger cosmopolitan and Gondwanan components. The latter group originated when Australia, as part of the ancient Gondwana supercontinent, was situated over Antarctic latitudes with a cooler, wetter climate than today. In the Wet Tropics, cool Gondwanan taxa occurred predominantly in upland and shaded lowland sites, but no species appeared narrowly temperature restricted, and there was no faunal zonation with altitude. Most chironomid species occurred at all latitudes within the Wet Tropics, with no evidence for an enduring effect of the historical rainforest contractions on current‐day distribution patterns. These findings contrast with those for aquatic faunas elsewhere in the world and for the terrestrial Wet Tropics fauna. We relate this to the generally broad environmental tolerances of Australian chironomids, and comment on why the latitudinal diversity gradient does not apply to the Australian chironomid fauna.     

Observations on the utilisation of a restored wildlife corridor by echo-locating microbats in North Queensland's Wet Tropics

Microbat studies are uncommon in the Wet Tropics of north-east Queensland, despite the group comprising 20% of the bioregion's mammal fauna. The significance of fragmentation and habitat connectivity to the echolocating insectivore group is unknown. Over a 12-month period in 2021–2022, microbat presence was recorded in a 25-year-old restored wildlife corridor 1.2 km in length. We deployed Anabat detectors in the restored corridor, in adjacent open paddocks and in mature rainforest at either end of the corridor. Species in reference forest and corridor vegetation were consistently ‘clutter-adapted’ bats, with low aspect ratio wings; there was little overlap with high aspect ratio species of the open pasture. Low aspect ratio microbats appear to respond to the similarity in structure between restored and adjacent natural vegetation. Re-establishing structural and functional connectivity may improve the local persistence of ‘clutter-adapted’ microbats.     

New approaches to understanding late Quaternary climate fluctuations and refugial dynamics in Australian wet tropical rain forests

Aim We created spatially explicit models of palaeovegetation stability for the rain forests of the Australia Wet Tropics. We accounted for the climatic fluctuations of the late Quaternary, improving upon previous palaeovegetation modelling for the region in terms of data, approach and coverage of predictions. Location Australian Wet Tropics. Methods We generated climate‐based distribution models for broad rain forest vegetation types using contemporary and reconstructed ‘pre‐clearing’ vegetation data. Models were projected onto previously published palaeoclimate scenarios dating to c. 18 kyr bp . Vegetation stability was estimated as the average likelihood that a location was suitable for rain forest through all climate scenarios. Uncertainty associated with model projections onto novel environmental conditions was also tracked. Results Upland rain forest was found to be the most stable of the wet forest vegetation types examined. We provide evidence that the lowland rain forests were largely extirpated from the region during the last glacial maximum, with only small, marginally suitable fragments persisting in two areas. Models generated using contemporary vegetation data underestimated the area of environmental space suitable for rain forest in historical time periods. Model uncertainty resulting from projection onto novel environmental conditions was low, but generally increased with the number of years before present being modelled. Main conclusions Climate fluctuations of the late Quaternary probably resulted in dramatic change in the extent of rain forest in the region. Pockets of high‐stability upland rain forest were identified, but extreme bottlenecks of area were predicted for lowland rain forest. These factors are expected to have had a dramatic impact on the historical dynamics of population connectivity and patterns of extinction and recolonization of dependent fauna. Finally, we found that models trained on contemporary vegetation data can be problematic for reconstructing vegetation patterns under novel environmental conditions. Climatic tolerances and the historical extent of vegetation may be underestimated when artificial vegetation boundaries imposed by land clearing are not taken into account.     

Macrophytes as indicators of stream condition in the wet tropics region,Northern Queensland,Australia

This study investigates the use of aquatic macrophytes as indicators of stream condition in catchments with varied land use and levels of riparian disturbance in the Wet Tropics region of North Queensland (Australia), a region of global significance in terms of faunal and floral diversity. In a paired catchment design spatial variations in macrophyte assemblage structure were characterised using multivariate and univariate techniques. Seven metrics were trialled: total macrophyte cover, species richness, % alien taxa, % native taxa, % submerged taxa, % emergent taxa and % Poaceae. Forty-four macrophyte taxa were recorded from the study area. Poaceae, Cyperaceae and mosses were the most frequently recorded taxa. Upper catchment areas in all tributaries surveyed were dominated by mosses and Cladopus queenslandicus (Domin) C.D.K. Cook (Podestemaceae). This assemblage occurred in areas with intact riparian canopy cover and good overall riparian condition. Macrophyte assemblages in lower catchment areas were distributed along gradients of riparian disturbance. Simultaneous autoregression model coefficients indicated that riparian condition had a negative influence on macrophyte cover, species richness and the proportions of alien taxa, emergent taxa and Poaceae present at sites in the Wet Tropics. Macrophyte metrics were not strongly influenced by the types of land use or water quality. These findings suggest that a riparian condition assessment would provide an adequate first assessment of the state of aquatic macrophyte assemblages in Wet Tropics streams.     

Fresh waters and fish diversity: distribution, protection and disturbance in tropical Australia

Background

Given the globally poor protection of fresh waters for their intrinsic ecological values, assessments are needed to determine how well fresh waters and supported fish species are incidentally protected within existing terrestrial protected-area networks, and to identify their vulnerability to human-induced disturbances. To date, gaps in data have severely constrained any attempt to explore the representation of fresh waters in tropical regions.

Methodology and Results

We determined the distribution of fresh waters and fish diversity in the Wet Tropics of Queensland, Australia. We then used distribution data of fresh waters, fish species, human-induced disturbances, and the terrestrial protected-area network to assess the effectiveness of terrestrial protected areas for fresh waters and fish species. We also identified human-induced disturbances likely to influence the effectiveness of freshwater protection and evaluated the vulnerability of fresh waters to these disturbances within and outside protected areas. The representation of fresh waters and fish species in the protected areas of the Wet Tropics is poor: 83% of stream types defined by order, 75% of wetland types, and 89% of fish species have less than 20% of their total Wet Tropics length, area or distribution completely within IUCN category II protected areas. Numerous disturbances affect fresh waters both within and outside of protected areas despite the high level of protection afforded to terrestrial areas in the Wet Tropics (>60% of the region). High-order streams and associated wetlands are influenced by the greatest number of human-induced disturbances and are also the least protected. Thirty-two percent of stream length upstream of protected areas has at least one human-induced disturbance present.

Conclusions/Significance

We demonstrate the need for greater consideration of explicit protection and off-reserve management for fresh waters and supported biodiversity by showing that, even in a region where terrestrial protection is high, it does not adequately capture fresh waters.     

Resistance and resilience: quantifying relative extinction risk in a diverse assemblage of Australian tropical rainforest vertebrates

Aim Assessing the relative vulnerability of species within an assemblage to extinction is crucial for conservation planning at the regional scale. Here, we quantify relative vulnerability to extinction, in terms of both resistance and resilience to environmental change, in an assemblage of tropical rainforest vertebrates. Location Wet Tropics Bioregion, north Queensland, Australia. Methods We collated data on 163 vertebrates that occur in the Australian Wet Tropics, including 24 frogs, 33 reptiles, 19 mammals and 87 birds. We used the ‘seven forms of rarity’ model to assess relative vulnerability or resistance to environmental change. We then develop a new analogous eight‐celled model to assess relative resilience, or potential to recover from environmental perturbation, based on reproductive output, potential for dispersal and climatic niche marginality. Results In the rarity model, our assemblage had more species very vulnerable and very resistant than expected by chance. There was a more even distribution of species over the categories in the resilience model. The three traits included in each model were not independent of each other; species that were widespread were also habitat generalists, while species with narrow geographical ranges tended to be locally abundant. In the resilience model, species with low reproductive output had a narrow climatic niche and also a low capacity to disperse. Frogs were the most vulnerable taxonomic group overall. The model categories were compared to current IUCN category of listed species, and the product of the two models was best correlated with IUCN listings. Main conclusions The models presented here offer an objective way to predict the resistance of a species to environmental change, and its capacity to recover from disturbance. The new resilience model has similar advantages to the rarity model, in that it uses simple information and is therefore useful for examining patterns in assemblages with many poorly known species.     

Prey use by dingoes in a contested landscape: Ecosystem service provider or biodiversity threat?

In Australia, dingoes (Canis lupus dingo) have been implicated in the decline and extinction of a number of vertebrate species. The lowland Wet Tropics of Queensland, Australia is a biologically rich area with many species of rainforest‐restricted vertebrates that could be threatened by dingoes; however, the ecological impacts of dingoes in this region are poorly understood. We determined the potential threat posed by dingoes to native vertebrates in the lowland Wet Tropics using dingo scat/stomach content and stable isotope analyses of hair from dingoes and potential prey species. Common mammals dominated dingo diets. We found no evidence of predation on threatened taxa or rainforest specialists within our study areas. The most significant prey species were northern brown bandicoots (Isoodon macrourus), canefield rats (Rattus sordidus), and agile wallabies (Macropus agilis). All are common species associated with relatively open grass/woodland habitats. Stable isotope analysis suggested that prey species sourced their nutrients primarily from open habitats and that prey choice, as identified by scat/stomach analysis alone, was a poor indicator of primary foraging habitats. In general, we find that prey use by dingoes in the lowland Wet Tropics does not pose a major threat to native and/or threatened fauna, including rainforest specialists. In fact, our results suggest that dingo predation on “pest” species may represent an important ecological service that outweighs potential biodiversity threats. A more targeted approach to managing wild canids is needed if the ecosystem services they provide in these contested landscapes are to be maintained, while simultaneously avoiding negative conservation or economic impacts.     

Linkage restoration: Interpreting fragmentation theory for the design of a rainforest linkage in the humid Wet Tropics of north-eastern Queensland

Summary Studies of forest fragmentation, particularly in the species-rich tropical zone, have contributed significantly to our understanding of its effects and impacts, and allow us to predict a cascade of flow-on effects likely to emerge in the coming decades. Practical management strategies to combat these effects, however, have not been forthcoming, despite intuitive assumptions and a growing body of scientific evidence that maintaining and restoring habitat connectivity is likely to be critical for the long-term persistence of many life forms in these fragmented landscapes. This paper reviews the potential problems involved with linkages, and examines some of the strategies adopted to overcome these issues in a linkage restoration project on the Atherton Tableland, in the Wet Tropics of north-eastern Australia. The paper concludes with the suggestion that restoration projects, such as the Donaghy's Corridor example, offer opportunities for researchers and practitioners to collaboratively observe and validate these strategies, and develop 'real world' techniques to reverse the ecological, social and economic effects of forest fragmentation.     

Presence and absence of non‐native fish species in the Wet Tropics region,Australia

Distributional records of non‐native fish species were identified in the Wet Tropics region, Far North Queensland, Australia, through a compilation of published records and expert knowledge. A total of 1106 records were identified comprising 346 presence and four uncertain records for at least 13 species, and 756 absence records. All current presence records consist of six species from the families Cichlidae and Poeciliidae with established self‐sustaining populations in the region, probably affecting the highly diverse native fish fauna.     

Biodiversity friend or foe: land use by a top predator,the dingo in contested landscapes of the Australian Wet Tropics

Dingoes (Canis dingo) in the coastal lowlands of Australia's Wet Tropics are perceived as a major threat to biodiversity and subjected to broad‐spectrum lethal control. However, evidence of their impacts is equivocal, and control programmes generally ignore the ecological benefits that dingoes might provide. Previous diet analysis has shown that dingoes in the Wet Tropics primarily prey on common, terrestrial mammals. However, little is known of dingo habitat use or prey acquisition in the region despite these activities having major implications for biodiversity conservation. We investigated land use by dingoes in the lowland Wet Tropics to enable predictions of potential prey types, relative prey use and modes of prey acquisition. Nine dingoes were tracked for 3–6 months. Home ranges and resting areas were estimated using multiple estimators, and habitat use was analysed using compositional analysis of habitat use and generalized additive models. Dingo ranging behaviour suggested that anthropogenic food subsidies were infrequently used. Each territory comprised several sclerophyll forest rest areas with adjacent sugarcane‐grassland high activity areas. Individuals used each rest‐activity area for extended durations before moving on to another. Sclerophyll and rainforests, which contain the fauna species of primary conservation concern, were generally used for rest/sleep, or movement between rest‐activity areas. Activity patterns were consistent with dingoes hunting in open sugarcane‐grassland habitats during daylight hours. Dingo activity was low in areas where fauna species of conservation concern occur, which suggests that dingoes do not pose a threat to their survival. Consequently, current broad‐spectrum lethal control may have minimal benefits or even incur costs for biodiversity. Maximizing the ecosystem services provided by dingoes while simultaneously minimizing their negative impacts requires a more targeted location‐specific management approach, one that assesses and mitigates impacts specifically where background circumstances suggest particular packs may be either a conservation or economic threat.     

Comparative phylogeography and the history of endemic vertebrates in the Wet Tropics rainforests of Australia

We examine the effects of historical climate change on vertebrate differentiation in tropical rainforest by comparing phylogeographic patterns in six species of widespread rainforest-restricted herpetofauna from throughout the Wet Tropics of Australia. Qualitative and quantitative comparisons of phylogeographic structure reveal strikingly similar patterns of pre-Pleistocene vicariant population differentiation on either side of a previously identified biogeographic break (variously referred to as the Black Mountain Barrier or Corridor; BMC). While divergence across the BMC antedates the Pleistocene, the impact of Quaternary climate change is apparent in populations on either side of the BMC. Consistent with palaeoclimatological reconstructions for the region, the distribution and degree of mtDNA diversity suggests that populations were fragmented and reduced to multiple refugia during Pleistocene glacial periods, with expansion following Holocene rainforest recovery. This pattern is repeated on both sides of the BMC, but substantial differences in the amount and distribution of mtDNA diversity within species indicate the importance of species-specific ecological characteristics. The historical processes of extinction and (re)colonization revealed by the comparative phylogeographic analysis of mtDNA sequences substantiate earlier suggestions that current regional patterns of species distribution and diversity in the Wet Tropics are largely determined by local extinctions and subsequent recolonization driven by Quaternary climate changes.     

Can changes in ant diversity along elevational gradients in tropical and subtropical Australian rainforests be used to detect a signal of past lowland biotic attrition?

Increasing temperatures are predicted to have profound effects on montane ecosystems. In tropical forests, biotic attrition may reduce lowland diversity if losses of species due to upslope range shifts are not matched by influxes of warmer‐adapted species, either because there are none or their dispersal is impeded. Australian rainforests consist of a north–south chain of patches, broken by dry corridors that are barriers to the dispersal of rainforest species. These rainforests have repeatedly contracted and expanded during Quaternary glacial cycles. Many lowland rainforests are expansions since the Last Glacial Maximum and may, therefore, show a signal of historical biotic attrition. We surveyed ants from replicated sites along three rainforest elevational transects in eastern Australia spanning 200 to 1200 m a.s.l. and nearly 14° of latitude. We examined elevational patterns of ant diversity and if there was possible evidence of lowland biotic attrition. Each transect was in a different biogeographic region; the Australian Wet Tropics (16.3°S), the central Queensland coast (21.1°S) and subtropical south‐eastern Queensland (28.1°S). We calculated ant species density (mean species per site) and species richness (estimated number of species by incorporating site‐to‐site species turnover) within elevational bands. Ant species density showed no signal of lowland attrition and was high at low and mid‐elevations and declined only at high elevations at all transects. Similarly, estimated species richness showed no evidence of lowland attrition in the Wet Tropics and subtropical south‐east Queensland; species richness peaked at low elevations and declined monotonically with increasing elevation. Persistence of lowland rainforest refugia in the Wet Tropics during the Last Glacial Maximum and latitudinal range shifts of ants in subtropical rainforests during the Holocene climatic optimum may have counteracted lowland biotic attrition. In central Queensland, however, estimated richness was similar in the lowlands and mid‐elevations, and few ant species were indicative of lower elevations. This may reflect historical biotic attrition due perhaps to a lack of lowland glacial refugia and the isolation of this region by a dry forest barrier to the north.     

Exotic vine invasions following cyclone disturbance in Australian Wet Tropics rainforests: A review

The Australian Wet Tropics region extends for almost 900 000 ha along the coastline of north‐east Queensland. The rainforests in this region have a rich and unique biodiversity and are World Heritage listed by UNESCO. Disturbance from tropical cyclones is a significant driver of the rainforest dynamics in this area, and when frequent or intense can facilitate the recruitment and expansion of exotic invasive species. Exotic vines are of particular concern for forest conservation as they can be highly competitive with native vegetation and may prevent forest regeneration. This literature review found evidence that fragmented forests, which are very common in the Australian Wet Tropics, are vulnerable to post‐cyclone vine invasion. In particular, although the diversity and abundance of herbaceous vines tend to decline as the canopy closes 2 years post‐cyclone disturbance, woody exotic vines and scramblers may persist for much longer or even increase in numbers. Since forest recovery in these systems is influenced by the severity and recurrence of disturbance, an increase in cyclone intensity under climate change may cause rapid changes in rainforest structure, composition and diversity, and increase exotic vine invasion. Post‐cyclone management of vines appears to require direct intervention, with manual cutting being currently the most effective method. However, there are a number of difficulties to its wide implementation in Australia, and further study on options for control is needed. Abstract in Spanish is available with online material.     

Mammalian Diet and Broad Hunting Strategy of the Dingo (Canis familiaris dingo) in the Wet Tropical Rain Forests of Northeastern Australia1

The diet of dingoes (Canis familiaris dingo) in the Australian Wet Tropics was examined by analyzing 383 dingo scats collected throughout the region for the presence of mammal prey remains. The scats yielded 29 native and 4 introduced mammal prey species from 14 families. The most important species in terms of percentage occurrence in the scats were Melomys cervinipes (22.2%), hoodon macrourus (17.0%), Perameles nasuta (12.5%), and Thylogale stigmatica (12.5%). The most important families were Muridae (37.1%), Peramelidae (29.5%), and Macropodidae (25.8%). Examination of small‐scale habitat preferences revealed species that preferentially use the forest edge ranked significantly higher in the diet than those that do not, and species that are terrestrial ranked higher in the diet than those that are arboreal. Relative abundance was also a significant factor in the ranked dietary occurrence of each species, with abundant species ranked significantly higher than those that are less abundant. These results suggest that dingoes in the Australian Wet Tropics are opportunistic predators of a wide variety of mammal species, with abundant terrestrial and forest edge‐dwelling taxa the most susceptible to predation.     

Altitudinal patterns of moth diversity in tropical and subtropical Australian rainforests

Altitudinal gradients are an excellent study tool to help understand the mechanisms shaping community assembly. We established a series of altitudinal gradients along the east coast of Australia to describe how the distribution of a hyper‐diverse herbivore group (night‐flying Lepidoptera) changes across an environmental gradient in subtropical and tropical rainforests. Two transects were in subtropical rainforest in the same bioregion, one in south‐east Queensland (28.7°S) and one in north east New South Wales (29.7°S). Two were in tropical rainforest, one in mid‐east Queensland (21.1°S) and one in the Wet Tropics of northern Queensland (17.5°S). Replicate plots were established in altitudinal bands separated by 200 m. Canopy and understorey moths were sampled at the beginning and end of the wet season using automatic Pennsylvania light traps. We sorted a total of 93 400 individuals, belonging to 3035 species. The two subtropical transects in the same region showed similar patterns of turnover across altitude, with the most distinctive assemblage occurring at the highest altitude. Moth assemblages in the tropical transects tended to show distinct ‘lowland’ and ‘upland’ communities. For species that were common across several of the transects, many were found at lower altitudes in the subtropics and higher altitudes in the tropics, suggesting they are sensitive to environmental conditions, and track their physiological envelopes across latitudes. These results suggest ubiquitous altitudinal stratification in tropical and subtropical Australian rainforests. The marked response of species to latitude and altitude demonstrates they are sensitive to climatic variables and can be used as indicators to understand future community responses to climate change.     

Problem solving of wild animals in the Wet Tropics of Queensland,Australia

While many species of animals can solve food-baited problems, most studies are conducted in captivity, which may not reflect the natural behavioural and cognitive abilities of wild animals. As few studies have explored problem solving of Australian animals generally, we investigated the problem solving abilities of native Australian species in natural rainforest in the Wet Tropics of Queensland. We baited multiple types of puzzles (matchbox task, cylinder task, and tile and lever tasks on a Trixie Dog Activity Board) with different food types (seeds, fruit, sardines) and placed the puzzles in front of trail cameras. We noted the species captured on camera, whether or not individuals interacted with the puzzles, the number of interactions with puzzles, and whether or not different animals solved them. We found that seven species from multiple taxa (mammals, birds, reptiles) could solve food-baited problems in the wild, providing the first evidence of problem solving in these native species. As problem solving may help animals cope with anthropogenic threats, these results provide some insights into which Wet Tropics species may potentially be more vulnerable and which ones might be better at coping with changing conditions.     

Cyclone damage to tropical rain forests: Species‐ and community‐level impacts

Abstract Severe Tropical Cyclone ‘Larry’ caused damage to 10 long‐term 0.5 ha monitoring plots in the rain forests of Queensland's Wet Tropics on 20 March 2006. We assessed the community‐level damage and the impact of the cyclone on the most abundant tree species in each plot. Damage was positively correlated with distance from the cyclone eye, though some plots received less damage than predicted owing to topographic shielding. Damage was patchy within plots, which is reflected in the range of damage‐classes recorded for each species, but there are broad trends in the type of response shown by different species. At the plot level, some species were either more susceptible or less susceptible to damage than the rest of the community. Species tended to show similar patterns of damage between plots with different community damage ratings. We discuss these response types in terms of adaptive tolerance to particular wind speeds and the trade‐off between frequently losing canopy volume in light winds, or rarely suffering substantial damage. We suggest that increased frequency of intense cyclones may affect the distribution of some species in the future, with those species most susceptible to high levels of damage at lower wind speeds becoming restricted to leeward‐facing slopes and upland areas away from the coast, and an increased abundance of resilient species in lowland coastal areas.     

The Photograph and the Malanggan: Rethinking images on Malakula,Vanuatu

From the recent efflorescence of anthropological engagements with photography we are by now aware that photography is an embodied practice and that photographs are complex materialisations of the subjective and experiential as well as the objective and evidential. Despite discussions of ‘visual repatriation’ (e.g. Brown and Peers 2006 ), and of local responses to colonial photography and other kinds of archival images in the Pacific, little has been discussed regarding the status of photographs as particularly ‘Pacific’ artefacts—objects that make sense in indigenous terms as well as being understood in terms of the connections to other places that their production and circulation might signify. Following Wright’s exhortation to recognise ‘the provincial nature of Eurocentric notions of photography and … suggesting that a certain corporeality and materiality constitute elements of its identity’ (2004: 74) , I discuss the resonance of historical photographs in Vanuatu, building an analogy with Malanggan—funerary carvings from Northern New Ireland. I do not mean to suggest that photographs are complex ritual artefacts, but rather follow the ways in which Malanggan have been used as anthropological conceits, in order to discuss the representational efficacy and materiality of Melanesian images in facilitating the crystallisation of memory and history ( Küchler 1988 ), the enchantment of technology ( Gell 1998, 1999 ), and the consolidation of certain kinds of property relations ( Strathern 2005b ). As my title suggests, I draw on Strathern’s combination of Malanggan and Patents to rethink the potential utility of Malanggan as a ‘way to think’ about the meanings of photographs in Pacific communities.
