Developing MPA performance indicators with local stakeholders’ input in the Pacific Rim National Park Reserve,Canada

Along with an increase in the establishment of marine protected areas (MPAs), the need arises to assess if designated MPAs are achieving their goals and objectives. A first step in this process is the identification of MPA performance indicators against which to evaluate MPA management. This study investigates the development of MPA performance indicators using an in situ approach by including diverse stakeholder groups in the process. The results show that local stakeholders identify a range of MPA performance indicators in all stages of the management cycle and in diverse MPA indicators categories. Statistical analysis reveals that multiple groups identify distinct performance indicators. Fishermen groups primarily mention governance performance indicators in the planning and output stage. Other groups most often cite biophysical and social outcome performance indicators. The findings demonstrate distinct management expectations towards MPA performance among included stakeholder groups. The study also shows that the integration of multiple groups is necessary for the identification of MPA performance indicators as the groups identify distinct performance indicators.     

Searching for thresholds in climate–radial growth relationships of Engelmann spruce and subalpine fir,Jasper National Park,Alberta, Canada

The relationship between monthly climate predictors and radial growth of Engelmann spruce (Picea engelmanni Parry) and subalpine fir (Abies lasiocarpa (Hook.) Nutt) were explored using both a standard dendroclimatological approach and a multiple adaptive regressions splines (MARS) framework. Consistent with previous research, the radial growth of fir and spruce was related to temperature variables over the time period of the instrumental record. We identify important temporal instability in the statistical relationships between climate variables and the radial growth of both subalpine fir and Engelmann spruce. Using a 30-year running window, only four of the climate variables related to the radial growth of either spruce or fir did not show a switch in the sign of the correlation. A multiple adaptive regressions spline method was then used to gain insight into thresholds that may relate to radial growth–climate instabilities. Using MARS, we were able to identify knots and non-monotonic relationships between radial growth and climate predictors that may be indicators of ecological thresholds. This combination of dendroclimatic methods provides valuable insight into the complex nonlinear responses that both subalpine fir and Engelmann spruce have been growing under in the past centuries.     

Suspensory locomotion of Lagothrix lagothricha and Ateles belzebuth in Yasuní National Park,Ecuador

A comparative field study of the locomotion of woolly monkeys (Lagothrix lagothricha) and spider monkeys (Ateles belzebuth) in undisturbed rainforest of northeastern Ecuador reveals substantial differences in their use of suspensory modes. Ateles performed both more brachiation (by forelimbs and tail, with trunk rotation), and forelimb swing (similar to brachiation, but without trunk rotation) than Lagothrix. In contrast, in Lagothrix 20% of suspensory movement was by pronograde forelimb swing, which resembles forelimb swing except that the body is held in a pronograde orientation due to the tail and/or feet intermittently grasping behind the trailing forelimb. Ateles never exhibited this mode. Both brachiation and forelimb swing by Ateles were more dynamic than in Lagothrix, consisting of higher proportions of full-stride bouts (versus single-step). Both species used smaller supports for suspensory than for quadrupedal locomotion, and Ateles used both smaller and larger supports for suspension than did Lagothrix. Analysis of support inclination shows that both species tended to perform more above-support movement on horizontal supports and more below-support (suspensory) movement from oblique supports. Our attempt to elucidate the aspects of canopy structure that favor suspension suggests the need for additional kinds of observational data, focusing on the "immediate structural context" of positional events.     

Valuation of Forests and Plant Species in Indigenous Territory and National Park Isiboro-Sécure,Bolivia

Valuation of Forests and Plant Species in Indigenous Territory and National Park Isiboro-Sécure, Bolivia. A quantitative ethnobotanical study was conducted in Indigenous Territory and National Park Isiboro-Sécure (TIPNIS), Bolivia, to assess the usefulness assigned by local Yuracaré and Trinitario ethnic groups to different terra firme and floodplain forests. Furthermore, we investigated which variables are good predictors for the use value attributed to plant species in the research area. Plants were collected during transect, walk-in-the-woods and homegarden sampling. Ethnobotanical and ethnoecological data of the inventoried plants were obtained from 12 Yuracaré and 14 Trinitario participants through semistructured interviews. On average, 84% of species in transects were claimed to be useful to people. The understorey (2.5 cm ≤ dbh < 10 cm) of the sampled forest types contained more useful species than the overstorey (dbh ≥ 10 cm), particularly for species with a medicinal and/or social use function. The local use value of plant species can be predicted, in part, from their botanical family, growth form, density, frequency, mean and maximum dbh, and ecological importance value. Our data confirm the hypothesis that density and frequency of plants in the landscape are both related to perceived plant accessibility. Accessibility of plants partly seems to guide their usefulness in TIPNIS. Indigenous assessment of accessibility and abundance of plants also covaried with their perceived usefulness and therefore has a potential for uncovering patterns in the perceived utility of plants.     

Assessment of human–leopard conflict in Machiara National Park,Azad Jammu and Kashmir,Pakistan

Livestock depredation by leopards is one of the key conservation issues in landscapes with limited resources worldwide. Any attempts to mitigate human–leopard conflict and conserve the species in conflict should be based on an unequivocal understanding of the conflict patterns. A household survey was conducted with an intention to quantify livestock losses resulting from depredation by leopards in and around the Machiara National Park, Azad Jammu and Kashmir, Pakistan. A total of 301 livestock were killed between June 2007 and August 2008 by leopards. The extent of loss varied in different months, with maximum killing occurring in the month of May. Small-bodied livestock such as goats and sheep were more vulnerable than large-bodied cattle. Goats were killed in significantly higher numbers as compared to other livestock. Domestic animals were killed more frequently at night as compared to other times of the day. There was a significant effect of the nighttime protection measures on depredation. Most attacks happened in valleys and in areas far from the forests. Factors most closely associated with livestock depredation included decline of natural prey, herding practices, guarding especially during the nighttime, and repeated use of pastures where predators were known to be hunting actively. Attitudes of the local community towards leopards were largely negative, and further efforts should be made to improve support for carnivore conservation. We suggest widespread local community education and proactive human–leopard conflict management, particularly through adopting carnivore-friendly livestock protection measures.     

Birds and biogeography of Mount Mecula in Mozambique’s Niassa National Reserve

The montane forests of northern Mozambique’s isolated massifs are inhabited by numerous range-restricted and threatened bird species, but until recently were extremely little-known. We report on a first avifaunal survey of the isolated montane habitats of Mt Mecula (1 442 m), Niassa National Reserve, notable as the only currently protected montane area in northern Mozambique. Mount Mecula’s moist forest is small (approximately 136 ha in total) and patchy, and although known botanically to have some montane affinities, was found to support an avifauna more typical of riparian forests of medium to low altitude. The only montane forest species recorded was Lemon Dove Aplopelia larvata. Other montane elements included Vincent’s Bunting Emberiza (capensis) vincenti, one of six species recorded new to the Niassa National Reserve list. Overall, it appears that despite its intermediate location, Mt Mecula does not represent a biogeographical ‘stepping stone’ for montane forest bird species. This probably owes to its remoteness from the Eastern Arc Mountains of Tanzania to the north and the massifs of other parts of northern Mozambique, to the south and west.     

Diversity of macrofungi and exploitation of edible mushroom resources in the National Park “Appennino Lucano,Val D'Agri,Lagonegrese” (Italy)

An investigation on the macrofungal diversity of the National Park “Appennino Lucano, Val D'Agri, Lagonegrese” (Basilicata, southern Italy) was carried out, together with an evaluation of wild edible mushrooms in agro-forest ecosystems and their possible exploitation as a new source of food and revenue in rural and under-developed areas of this region. An unpublished list of 249 mushroom taxa (229 Basidiomycota and 20 Ascomycota), mostly belonging to the genera Tricholoma, Tuber, Russula, Amanita, Boletus, Lactarius, Mycena, Agaricus, Clitocybe and Hygrophorus, growing in this important natural area is provided together with ecological characterization of the recorded specimens. Inonotus obliquus is a new record for Basilicata, while Mycena bresadolana is reported for the first time from southern Italy. The presence of Amaurodon mustialaënsis, an extremely rare species of the northern hemisphere reported for the first time on white fir, is noteworthy. Among the previous findings, 116 species of edible mushrooms are presented and discussed in view of their relative abundance and edibility.     

Rotifers in ephemeral ponds of Doñana National Park

32 ephemeral dune ponds were studied at the end of January 1990. 34 rotifer species were identified. The distribution of only a few species was related to salinity, suspended matter, chlorophyll-a and total water protein concentrations. However, most of the species seem to be better related to the colonization possibilities than to the environmental characteristics of the ponds.     

Uses and Conservation of Plant Species in a National Park—A Case Study of Ben En, Vietnam

Uses and Conservation of Plant Species in a National Park—A Case Study of Ben En, Vietnam. This paper surveys the use of wild and cultivated plants by local people in Ben En National Park, Vietnam, and analyzes its impact on the conservation status of some of the utilized species. A total of 208 species used for a range of nonmedicinal purposes are listed. See Hoang et al. (2008a) for 230 medicinal plants used in the park. Most species are used for food. The use of plants contributes very significantly to the livelihood of local people in the park, but the current use patterns are not sustainable and would lead to local extinction of rare and endangered species if no additional conservation measures are introduced. Men collect nonmedicinal plants more often than women. A total of 38 useful plant species are commercialized, and contribute 12% of the average income of individual households. Bamboo shoots of Schizostachyum funghomii (Poaceae) are the most important for income generation. The monetary equivalent of noncommercialized useful plants probably far exceeds the value of the traded plant products. Plant use is independent of the ethnicity of the different populations living in the park. Larger households make use of a greater variety of useful plant species than small families. Abundant species in the forest have a higher use index (UI) than less common species. Out of the 208 useful species, as many as 27 were found to be endangered locally, many more than the 11 or 8 endangered species included in national or global red lists. Currently, useful plants, especially important timber trees, are more abundant in the less disturbed parts of the park, far away from the villages, indicating the pressures of illegal logging and harvesting near villages on the ecosystems.     

Mosquitoes of the Jaú National Park and their potential importance in Brazilian Amazonia

Abstract. An entomological inventory was conducted between 1993 and 1996 to obtain information on the diversity of mosquitoes (Diptera: Culicidae) in the Jaú National Park, State of Amazonas, Brazil. A total of 10,159 adult (91%) and immature mosquito specimens, representing 130 taxa (species + morphospecies) in 16 genera, was collected. A species list for the family Culicidae is presented, including 30 new records for the State of Amazonas. The collecting localities were restricted to the alluvial subregion of the Open Tropical Forest found in the park. Most of the specimens (71%) were collected in forest habitats and the rest in areas of second growth and peridomicile. The majority of immature specimens (46%) were collected in bodies of water along the edges of rivers, flooded forests, lakes and streams. Among the various collection methods used, the Centre for Disease Control (CDC) and Shannon traps together were responsible for capturing 60% of the adults. More than 90% of the material collected belongs to the genera Culex (65%), Psorophora (19%), Wyeomyia (4%), and Anopheles (3%), which together represent 70% of the identified taxa. The genus Culex presented the largest number of species (45). The species Culex (Melanoconion) vaxus, Cx. (Mel.) pedroi, Psorophora amazonica, Cx. (Mel.) portesi and Cx. (Mel.) theobaldi together (< 4% of the recorded species) represent more than 63% of the material collected and identified to the species level. The most abundant species was Cx. (Mel.) vaxus, representing 17% of the material identified to species. The possible epidemiological and ecological implications of the species hereby recorded in the Jaú National Park are presented and discussed.     

Batrachochytrium dendrobatidis infection of amphibians in the Doñana National Park, Spain

Amphibian chytridiomycosis, caused by infection with the non-hyphal, zoosporic chytrid fungus Batrachochytrium dendrobatidis (Bd), is an emerging infectious disease recognised as a cause of recent amphibian population declines and extinctions worldwide. The Do?ana National Park (DNP) is located in southwestern Spain, a country with widespread Bd infection. This protected area has a great diversity of aquatic habitats that constitute important breeding habitats for 11 native amphibian species. We sampled 625 amphibians in December 2007 and February to March 2008, months that correspond to the early and intermediate breeding seasons for amphibians, respectively. We found 7 of 9 sampled species to be infected with Bd and found differences in prevalence between sampling periods. Although some amphibians tested had higher intensities of infection than others, all animals sampled were apparently healthy and, so far, there has been no evidence of either unusually high rates of mortality or amphibian population declines in the DNP.     

Dyadic associations of red Colobus and diana monkey groups in the Taï National Park, Ivory Coast

Members of the genus Colobus have been observed to associate frequently with Cercopithecus monkeys in several African sites. In the Taï National Park, Ivory Coast, one group of western red colobus was found to be in association with one particular group of diana monkeys more than could be expected by chance (Holenweg et al., 1996). We show that dyadic association is not an idiosyncrasy of these two groups, but rather a pattern that is general for our study site. All five red colobus groups we studied were closely associated with diana monkeys during more than 60% of the time. Four groups had one particular diana partner group, the fifth two different partners. Apart from the red colobus, three more primate species, the olive colobus, Campbell's monkey, and the lesser spot-nosed monkey, were also strongly attracted to diana monkeys.     

Residues of brodifacoum and other anticoagulant pesticides in target and non‐target species,Nelson Lakes National Park,New Zealand

Abstract

Cereal‐based bait containing 20 ppm brodifacoum was used in bait stations continuously from December 1997 to August 2000 in the Rotoiti Nature Recovery Project area, for controlling brushtail possum (Trichosurus vulpecula), ship rat (Rattus rattus), and house mouse (Mus musculus) populations. Concurrently (and before and after), baits containing brodifacoum, bromadiolone, flocoumafen, coumatetralyl, or warfarin were also used in St Arnaud village and on farms immediately adjacent to the project area. Brodifacoum residues were detected in the livers of 234 mammals from eight species, and two birds from two species captured alive, and a further seven birds from five species found dead in the project area (cause of death unknown). The highest concentration of brodifacoum residues in mammalian livers was recorded during the period brodifacoum was used in the project area. However, residues were present in the livers of some individuals at least 24 months after brodifacoum use in the project area stopped. These residues may have persisted in animals surviving brodifacoum use in the project area, and/or been transported into the area by animals moving to and from the adjacent village and farms, where brodifacoum use continued. Residues of flocoumafen, coumatetralyl, or warfarin, used only in the village and on farms, were also detected in the livers of animals captured up to at least 8 km from the nearest source. The results concur with other studies cautioning against indiscriminate or prolonged use of persistent anticoagulants for vertebrate pest control. However, the risks from such pesticides must be balanced against the demonstrable benefits of reducing pest abundance.     

Diet composition and selection of Père David's deer in Hubei Shishou Milu National Nature Reserve,China

Hubei Shishou Milu National Nature Reserve is an ideal place to restore the wild population of Père David's deer (Elaphurus davidianus). Understanding foraging ecology and diet composition is essential for assessing population development or establishing long-term effective conservation measures for endangered species. However, little is known about the diet composition of Père David's deer and its diet selection mechanism. In this study, we used stable isotope technology to investigate the diet composition of Père David's deer according to various tissues (i.e., fur, muscle, liver, heart, and feces) and seasons, and evaluated the correlation between the nutrient composition of plants and diet composition. Bayesian isotope analysis showed that the autumn and winter diet estimated by fur and fecal samples indicated a diet dominated by C₃ grasses (42.7%–57.2%, mean), while the summer diet estimated by muscle and liver samples was dominated by C₃ forbs (30.9%–41.6%, mean). The Pearson correlation test indicated that the contribution of winter diet composition reflected by fur and fecal samples was associated with correlations with crude protein (r = .666, p < .01) and soluble sugars (r = .695, p < .01). The results indicated that crude protein and soluble sugars were important factors influencing the winter diet selection of Père David's deer. In the context of the current reintroduction facing many challenges, such as habitat fragmentation, wetland degradation, and human disturbance, comprehensively evaluating the diet selection mechanism of Père David's deer under different resource specificities and temporal changes should be considered in the future.     

Morphology and phenology of seeds and whole fruit eaten by Milne-Edwards’ sifaka,Propithecus diadema edwardsi,in Ranomafana National Park,Madagascar

Although it is an anatomical folivore, the diet of the Milne-Edwards’ sifaka (Propithecus diadema edwardsiA. Grandidier, 1871) in Ranomafana National Park contained 35% seeds, 30% whole fruit, and 28% leaves. Plant species used as seed sources differed from those used as whole fruit sources in terms of temporal variation in consumption, taxonomic affiliation, morphology, and phenology. Although seeds were destroyed in both exploitation styles used by the sifakas—seed and whole fruit-eating—the gross morphology of species used as seed sources conformed to the complex of traits typical for fruits experiencing seed predation, while species used as whole fruit sources conformed to traits typical for fruits that do not experience predispersal predation. Many of the 19 plant species from which the seed was extracted and eaten contained a single seed with moderate testa thickness, and fruits containing this type of seed were medium-sized with dry or fibrous flesh, moderate skin thickness, and a dull color. In contrast, brightly colored, juicy fruits with minimally protected seeds were characteristic of the 38 plant species from which both pericarp and seed were eaten. Compared to transectwide measures of fruit availability or patterns restricted to whole fruit sources, fewer species of seed sources produced fruit per month and fruiting activity was more seasonal.     

Flamingo ‘rescue’ in Etosha National Park, 1994: technical,conservation and economic considerations

Fox, V.E., Lindeque, P.M., Simmons, R.E., Berry, H.H., Brain, C. & Braby, R. 1997. Flamingo ‘rescue’ in Etosha National Park, 1994: technical, conservation and economic considerations. Ostrich 68 (2–4): 72–76.

During April 1994,144 Greater Flamingo Phoenicopterus ruber chicks were taken from Etosha Pan, Namibia, following drying of the shallow water and the death of hundreds of chicks. The captured chicks ranged from approximately 2 weeks to 2 months of age and were hand-reared at Okaukuejo until being released (7 weeks later) or sold (12 weeks later). Fourteen birds died within 8 days; only two died later. Of 77 chicks released at Walvis Bay, their traditional wintering grounds, 76 were fitted with yellow plastic rings and 73 with numbered metal rings. These grey juveniles were highly visible in the lagoon among the pink adults, and were resighted regularly. Most of the 20 birds recovered dead within two months of release were birds with wing chord measurements less than 315 mm, and black-backed jackal Canis mesomelas predation was the most likely cause of death. Bird counts 11 and 14 months later at Walvis Bay and surrounding wetlands revealed no juveniles at all, suggesting high mortality. However, four ringed flamingos were sighted in Jan. 1997, and one debilitated ringed flamingo was recovered at the Namibia-Botswana border in Feb. 1997. A lack of predator avoidance was thought to be the main factor responsible for the high mortalities.     

Distribution and abundance of four caiman species (Crocodylia: Alligatoridae) in Jaú National Park,Amazonas, Brazil

Jaú National Park is a large rain forest reserve that contains small populations of four caiman species. We sampled crocodilian populations during 30 surveys over a period of four years in five study areas. We found the mean abundance of caiman species to be very low (1.0 +/- 0.5 caiman/km of shoreline), independent of habitat type (river, stream or lake) and season. While abundance was almost equal, the species' composition varied in different waterbody and study areas. We analysed the structure similarity of this assemblage. Lake and river habitats were the most similar habitats, and inhabited by at least two species, mainly Caiman crocodilus and Melanosuchus niger. However, those species can also inhabit streams. Streams were the most dissimilar habitats studied and also had two other species: Paleosuchus trigonatus and P. palpebrosus. The structure of these assemblage does not suggest a pattern of species associated and separated by habitat. Trends in species relationships had a negative correlation with species of similar size, C. crocodilus and P. trigonatus, and an apparent complete exclusion of M. niger and P. trigonatus. Microhabitat analysis suggests a slender habitat partitioning. P. trigonatus was absent from river and lake Igapó (flooded forest), but frequent in stream Igapó. This species was the most terrestrial and found in microhabitats similar to C. crocodilus (shallow waters, slow current). Melanosuchus niger inhabits deep, fast moving waters in different study areas. Despite inhabiting the same waterbodies in many surveys, M. niger and C. crocodilus did not share the same microhabitats. Paleosuchus palpebrosus was observed only in running waters and never in stagnant lake habitats. Cluster analysis revealed three survey groups: two constitute a mosaic in floodplains, (a) a cluster with both M. niger and C. crocodilus, and another (b) with only C. crocodilus. A third cluster (c) included more species, and the presence of Paleosuchus species. There was no significant difference among wariness of caimans between disturbed and undisturbed localities. However, there was a clear trend to increase wariness during the course of consecutive surveys at four localities, suggesting that we, more than local inhabitants, had disturbed caimans. The factors that are limiting caiman populations can be independent of human exploitation. Currently in Amazonia, increased the pressure of hunting, habitat loss and habitat alteration, and there is no evidence of widespread recovery of caiman populations. In large reserves as Jaú without many disturbance, most caiman populations can be low density, suggesting that in blackwater environments their recovery from exploitation should be very slow.     

Feeding ecology of Lilian’s Lovebird Agapornis lilianae in Liwonde National Park,Malawi

Lilian's Lovebird Agapornis lilianae is a small, near-threatened parrot resident in mopane Colophospermum mopane woodlands. We investigated its diet and foraging behaviour in Liwonde National Park, Malawi. We expected that Lilian's Lovebirds would show little specialisation for a particular food source but generally feed on available seeds, fruits, flowers and other items as observed in other lovebirds. Lilian's Lovebirds fed on 30 different plant species. Lilian's Lovebirds were observed feeding in six habitat types in Liwonde National Park and adjacent areas during the wet season, and four in the dry season. In the wet season lovebirds (23% of observations) foraged in grassy wetland (dambo) areas the most, whilst in the dry season they foraged in grasslands with tree cover (18%) the most. In mopane woodland, foraging flock sizes differed significantly between the wet (mean = 19.8 ± 1.0 lovebirds) and dry season (mean = 33.6 ± 2.3 lovebirds). Grass seeds were lovebirds’ main food source from December to June. The nutritional analysis of preferred foods showed that grass seeds have a relatively high protein and energy content. Grass seed availability is reduced with savanna burning and so early season burning (before May–June) in areas in and outside the park is not recommended.     

Where,When and Why Do Tsetse Contact Humans? Answers from Studies in a National Park of Zimbabwe

Background

Sleeping sickness, also called human African trypanosomiasis, is transmitted by the tsetse, a blood-sucking fly confined to sub-Saharan Africa. The form of the disease in West and Central Africa is carried mainly by species of tsetse that inhabit riverine woodland and feed avidly on humans. In contrast, the vectors for the East and Southern African form of the disease are usually savannah species that feed mostly on wild and domestic animals and bite humans infrequently, mainly because the odours produced by humans can be repellent. Hence, it takes a long time to catch many savannah tsetse from people, which in turn means that studies of the nature of contact between savannah tsetse and humans, and the ways of minimizing it, have been largely neglected.

Methodology/Principal Findings

The savannah tsetse, Glossina morsitans morsitans and G. pallidipes, were caught from men in the Mana Pools National park of Zimbabwe. Mostly the catch consisted of young G. m. morsitans, with little food reserve. Catches were increased by 4–8 times if the men were walking, not stationary, and increased about ten times more if they rode on a truck at 10 km/h. Catches were unaffected if the men used deodorant or were baited with artificial ox odour, but declined by about 95% if the men were with an ox. Surprisingly, men pursuing their normal daily activities were bitten about as much when in or near buildings as when in woodland. Catches from oxen and a standard ox-like trap were poor indices of the number and physiological state of tsetse attacking men.

Conclusion/Significance

The search for new strategies to minimize the contact between humans and savannah tsetse should focus on that occurring in buildings and vehicles. There is a need to design a man-like trap to help to provide an index of sleeping sickness risk.
