THINKING THROUGH IMAGES: KASTOM AND THE COMING OF THE BAHA'IS TO NORTHERN NEW IRELAND, PAPUA NEW GUINEA

We can learn a lot about religious ideas by studying not just the impact on them of missionization but also how religious beliefs and practices are translated into local religious forms. In this article I draw attention to the case of the Baha'i faith in the Nalik area of northern New Ireland (Papua New Guinea). In discussing how the faith became strongly associated with the ability to harness ancestral power, I argue that this relationship emerged through Nalik people's ability to think through images, in other words through transforming forms in order to create new understandings. This study not only underlines the importance of localized studies into the technology of image production but also fills a gap in anthropological studies that, up until now, have systematically ignored the Baha'i movement and its place in the contemporary Pacific.     

THE RELATIONSHIP OF THE SOUTHERN NIGERIAN AVIFAUNA TO THOSE OF UPPER AND LOWER GUINEA

The composition of the forest avifauna of Southern Nigeria is analysed in the light of the most recent work in the region. It is found that east of the Niger the affinities are with Lower Guinea: at Lagos with Upper Guinea; in the Ondo-Benin area not definitely with either. A discussion of the barriers between the two sub-regions follows, and it is claimed that, whereas the Lagos-Accra savanna gap and the Cameroon montane area can each account for about one quarter of the total change, factors within Nigeria were almost twice as important in causing differentiation. It is suggested that these factors were a combination of climatic conditions and northward position of the coastline in late or post-Pliocene times, giving rise to a condition similar to that we find today between Lagos and Accra.     

SEA-BIRDS AT LAGOS AND IN THE GULF OF GUINEA

Regular observations of sea-birds were made in the vicinity of Lagos, southwest Nigeria, between October 1967 and June 1971. Records in the Gulf of Guinea were obtained in April 1969 and, together with others from Ghana and Sierra Leone, were used to complement this study. While few large populations of sea-birds are supported, the diversity of species occurring at Lagos and over offshore deep water was great. The occurrence of nine species of sea-bird new to Nigeria was established or confirmed; most of these were also new to West Africa southeast of Gambia. Details are given of fluctuations in numbers these and a further 16 species.
All coastal habitats at Lagos supported a large population of immature Black Terns, and groups of immatures made up a high proportion of observations of other Palaearctic terns and of Royal Terns, which breed only in northwest Africa. In contrast, the Lesser Black-backed Gulls and Damara Terns reaching Lagos (from breeding grounds almost two continents apart) were mainly adults; both these species are amongst those showing a current increase in numbers. A pronounced spring passage was observed among species including Royal and Sandwich Terns, but adult movements in autumn were not elucidated. The occurrence of the European race of the Little Tern in southwest Nigeria was confirmed, it is at least a regular spring migrant. The frequency of vagrants in January and February was linked to local climate as much to general distribution. Brief comment is also given on immature plumages, and the growing exploitation and pollution of coastal waters.     

SEAWEED ABUNDANCE AND DIVERSITY IN HIGH ENERGY AND LOW ENERGY AREAS AT PORT ARANSAS,TEXAS JETTIES

Agan, J. C. & Lehman, R. L. Department of Physical and Life Sciences, Texas A&M University-Corpus Christi 6300 Ocean Dr., Corpus Christi, TX 78412 USA Benthic algal sampling from high and low energy zones at a selected site on the south jetty at Port Aransas, Texas was completed between April 1999 and February 2000. Species composition and seasonal periodicity in relation to temperature and salinity fluctuations were determined. Dominant plants throughout the year included Bryocladia cuspidata, Bryocladia thyrsigera, Gelidium pusillum, Centroceras clavulatum, Ulva fasciata, and Padina gymnospora. The Rhodophyta dominated species coverage, along with biomass accumulation, although Chlorophyta species accrued the greatest biomass on the high energy side in April and June sampling. Chlorophyta are important to benthic coverage and biomass in the shallowest of waters, despite being fewer in species richness. Phaeophyta species including Petalonia fascia, Hincksia mitchelliae, and Ectocarpus siliculosus were found only during the cooler months. Padina gymnospora was the one exception as it was collected year-round. Results indicate that a greater Rhodophyta abundance was found on the channel side (low energy), where as, the surf side (high energy) contained a greater Chlorophyta abundance. Phaeophyta abundance for both high and low energy sites were comparable possibly due to the greater depth of water in which they are located. Little variance occurred in average biomass accumulation throughout the year. Highest biomass was in August (216.613g dry weight) with lowest occurring in April (107.4205g dry weight).     

COMPOSITION,ABUNDANCE AND SEASONALITY OF LARVAL FISH IN RICHARDS BAY HARBOUR,KWAZULU-NATAL,SOUTH AFRICA

Summary

The present study examined the composition, abundance and seasonality of fish larvae occurring in Richards Bay Harbour, over an 18-month period from June 1991 to November 1992. Ichthyoplankton samples were collected every six weeks at top, mid and bottom depths in the dredged channel 100 to 200 m from the harbour entrance. A total of 7 163 fish larvae, representing 105 taxa and 53 families, was collected throughout the study period. The dominant families were the Engraulidae and Gobiidae representing 50% and 37% of the total catch, respectively. The most abundant larvae were those of the thorny anchovy, Stolephorus holodon, and an unidentified goby, Gobiid 12 (32% and 30% of the total catch, respectively). Estuarine-associated taxa dominated the total catch in terms of density (61%), with 11 out of the 28 taxa being totally dependent on estuaries at some stage in their life cycle. Turbidity and temperature were significant variables accounting for 27% of the variation in larval densities of estuarine-dependent species. The main peak in larval density occurred in January 1992 (summer) with a mean larval density of 160 larvae per 100 m³. Larvae of estuarine-associated taxa were predominantly at the flexion and postflexion developmental stages. Since larval densities of certain estuarine-associated species were significantly greater in bottom samples and on flood tides, it is suggested that selective tidal stream transport is a recruitment mechanism used by these species. The present study concluded that it is important to maintain and preserve the estuarine component of Richards Bay Harbour so that the system can function as an estuarine nursery for many of the fish species depending on it at certain stages in their life cycle.     

THREE NEW SPECIES OF POLISTES LATREILLE (HYMENOPTERA: VESPIDAE) FROM PAPUA NEW GUINEA, WITH NOTES ON THE TAXONOMIC STATUS OF THE SUBGENUS STENOPOLISTES VAN DER VECHT

Abstract
Three new species of Polistes Latreille are described from Papua New Guinea. Of these, P. occultus sp. n. largely fits the diagnosis of the subgenus Stenopolistes van der Vecht. However, while P. watutus sp. n. and P. medius sp. n. have the jugal lobe of the hind wing defined by a wide incision (an apomorphic character of Stenopolistes ), in the other characters distinguishing Stenopolistes and the subgenus Polistella Ashmead have states typical of Polistella. If Stenopolistes is regarded as a subgenus, then Polistella is defined only by a symplesiomorphy, thus Stenopolistes must be synonymised under Polistella.     

ORIGIN OF THE AVIFAUNA OF URBAN AND SUBURBAN SINGAPORE

A list of the commoner garden and town birds of the tropical city of Singapore is given. None of them are birds of the rain forest which formerly covered the island. The majority are coastal species the natural habitats of which were mangrove and the thin fringe of savanna along parts of the east coast of the Malayan Peninsula. The reasons for this are discussed.
The number of garden species is comparatively small and many niches appear to be vacant. These are expected to be filled mainly by open country species moving down the peninsula from Burma and Thailand along the corridors being opened up by deforestation. This process has already begun, though few species have yet reached as far south as Singapore.
The garden avifauna is unstable and numerous changes in status have occurred in the last few decades; many more are predicted.     

THE DISTRIBUTION, ABUNDANCE AND SELECTED PREY OF THE HARBOR SEAL, PHOCA VITULINA CONCOLOR, IN SOUTHERN NEW ENGLAND

The seasonal distribution and abundance of harbor seals occurring south of Maine were documented by counting the number of seals at traditional haulout locations. The average number of seals counted during each survey in Massachusetts and New Hampshire was 3,560 ± 255 (95% CI), 1983–1987. The maximum number of seals counted on any individual survey was 4,736 individuals. Fifty percent of all the surveys since January 1985 have resulted in counts greater than 4,000 seals reflecting a 27% increase in the abundance of seals in our study area since that date. Seventy-five percent of the seals in southern New England are located at haulout sites on Cape Cod and Nantucket Island. The largest aggregation of seals in the eastern United States occurs mid-winter at Monomoy Island and adjacent shoals. A single high count of 1,672 seals occurred at this site during the study period. An additional 271–374 seals were also counted in Rhode Island, Connecticut and eastern Long Island Sound during surveys conducted in March 1986 and 1987. The American sandlance Ammodytes americanus was the single dominant prey item of harbor seals in waters adjacent to Cape Cod based on the modified frequency of occurrence of each prey species in scat samples collected from three haulout sites on Cape Cod between 1984–1987. During January and February sandlance was the near exclusive prey item at Monomoy (99%, n= 80). During March and April, the frequency of Atlantic herring Clupea harengus increased in the scat samples at this site. Regional differences in the diet of seals reflect distinct prey communities throughout the study area. Since 1986, the percent occurrence and importance of sandlance in the diet of seals has decreased, reflecting an overall decrease in abundance of this prey species in waters adjacent to Cape Cod. In spite of fluctuations in abundance, and regional differences in the diet of seals throughout the study area, sandlance still comprised a minimum 55% of the total prey species of harbor seals throughout the study area.
