Reef Fish Community

In order to look at changes in coral and reef fish communities during the period of 2006 to 2013, this research was carried out at Bunaken National Park (BNP) with 26 observation sites. The existing data and information of reef fish communities in the park generally could not be used as representative for describing the whole region. Percentage of coral cover and fish abundance during the study period shows that Bunaken Island is more similar to other locations. Reef fish community structure as seen from ecological index (H' at all sites being categorized, E category labile and low category C) shows the condition of the reef fish community is still good. Changes in the structure of reef fish communities showed declining conditions compared to 2006, and coral cover continued to decrease compared to 1998 and 2007. Good overall reef fish and coral cover have decreased; it is thought to be related to the pressure in BNP. Some of the pressures in the region were (i) increasing numbers of domestic as well as foreign visitors, (ii) increasing number of residents in the region, as well as the burden of waste and trash from the Bay of Manado. Penelitian dilakukan di Taman Nasional Bunaken (Utara dan Selatan)   pada 26 lokasi  pengamatan untuk menganalisis perubahan struktur komunitas ikan karang melalui kajian dari suatu time series data dari beberapa penelitian sebelumnya. Data primer mengenai ikan-ikan karang diperoleh melalui visual sensus bawah air yang bersamaan dengan observasi terumbu karang menggunakan point intercept transect. Nilai persentase tutupan karang dan kelimpahan ikan menunjukkan bahwa pada lokasi pengamatan Pulau Bunaken paling baik dibandingan lokasi lainnya. Struktur komunitas ikan karang yang dianalisis dengan indeks ekologi menunjukkan indeks keanekaragaman (H’) di semua site masuk kategori sedang, indeks kesamaan (E) kategori labil dan indeks Dominansi (C) kategori rendah. Hasil penelitian ini menunjukkan bahwa kondisi komunitas ikan karang masih baik, sekalipun  perubahan struktur komunitas ikan karang menunjukkan kondisi yang menurun dibandingkan tahun 2006, begitu juga tutupan karang yang terus turun dibandingkan tahun 1998 dan 2007. Secara keseluruhan baik ikan karang maupun tutupan karang mengalami penurunan, hal ini diduga terkait dengan tekanan yang dialami kawasan TN. Bunaken. Salah satu tekanan terhadap kawasan adalah jumlah turis dari dalam maupun luar negeri yang semakin meningkat tiap tahunnya, penambahan jumlah penduduk di dalam kawasan, serta beban limbah dan sampah dari Teluk Manado.

One of India's five major populations of elephants lives in north-west India, where 90 per cent of the total 750 elephants occur in Rajaji and Corbett National Parks and adjacent reserve forests. This 3000-sq-km habitat is also home to many other endangered species. While the 520-sq-km core area of Corbett National Park is free from human impact, the rest of the range is subject to increasing pressures, both from the pastoral Gujjar community within the forests and villagers outside. The elephant habitat has been fragmented by hydrological development work and human-elephant conflict is increasing. The authors recommend measures that need to be implemented to ensure that the elephants and other wildlife of the area are conserved.

Abstract The scale of impact that the São Francisco River transposition project will have on the drainage basins ichthyofauna is still unclear, however, changes in the fish community diversity and abundance is probable. Surveys and registries of the fish fauna within key systems of the catchment basins are priority actions for the conservation of the aquatic diversity. This study conducted a taxonomic survey of the Epitácio Pessoa (Boqueirão municipality) and Argemiro de Figueiredo (Itatuba municipality), reservoirs ichthyofauna, both belonging to the Paraíba do Norte River basin, important socioeconomic and environmental systems for the transposition project. Monthly sampling was carried out between October/2014 to September/2015 in the upstream and downstream zones of the reservoirs. The specimens were collected using dip nets, drag nets, and sieves, and placed on ice in the field. Later in the laboratory, they were transferred to 10% formaldehyde and then preserved in 70% alcohol. A total of 2,328 specimens were collected representing five orders, 14 families, and 31 species in both systems. At the upstream zones 2057 specimens were collected representing 17 species, and at the downstream zones 271 specimens were collected representing 24 species. Of the 31 species recorded, 13 species are endemic to watersheds that drain rivers from the Brazilian semi-arid region, and seven species (Apareiodon davisi, Characidium bimaculatum, Hypostomus pusarum, Parotocinclus jumbo, P. spilosoma, Pimelodella enochi, and Prochilodus brevis) are endemic to the Mid-Northeastern Caatinga Ecoregion (MNCE). Among the latter, Parotocinclus spilosoma and Pimelodella enochi are endemic to the Paraíba do Norte River. Apareiodon davisi is classified as Endangered according to the current published Brazil’s official list of endangered species of fish and aquatic invertebrates. This pre-transposition ichthyofaunistic survey will serve as a basis for future post-transposition analyzes, considering this action will change the scope of the ecosystems diversity.

The Chitawan Wildlife Sanctuary in the Rapti River valley in Nepal together with the Mahendra National Park are the home of die great Indian rhinoceros, one of the world's endangered species. In 1959 and 1963 Mr. E. P. Gee, noted Indian conservationist, made surveys of the area, the second one at the request of the FPS; his reports published in ORYX (1959, V, 57, and 1963, VII, 67) drew attention to the decrease in the number of rhinos, due to poaching, from about 300 animals in 1959 to 160 in 1961, and the large amount of illegal settlement in the National Park. Mr. Willan, who is Chief Conservator of Forests in Nepal, continues the story since then with the encouraging news of the clearing of all illegal settlement from the park and also from the extension, the latter on the orders of HM King Mahendra, and the proper demarcation and accurate mapping of the sanctuary, which it is hoped will be created a National Park. Rhinos are now quite frequently seen, and between January and September this year 35 rhino calves were reported.

The recolonization of stones by macroinvertebrates in streams can occur at very small temporal scales, an often-neglected factor in recolonization studies. In a tropical stream in Coiba National Park, Panama, 36 stones were washed and brushed and each one was subjected to four different periods of exposure in a riffle (1, 3, 9, 27 h). Ephemeroptera, together with Diptera, Trichoptera, Coleoptera, Lepidoptera and Hydracarina, were the main recolonizers. Total density of individuals, and density and relative abundance of the most common taxon (Baetidae : Ephemeroptera), showed significant variation over the four recolonization periods, partially explained by some abiotic variables (water depth, current velocity and stone shape). Taxa richness, community evenness and taxonomic composition did not vary significantly over the four periods. The recolonization of stones in the tropical stream began immediately after the disturbance, although only some community characteristics varied significantly over the first hours.

Demographic Shifts

The value of traditional ecological knowledge for biodiversity research and conservation is widely recognized. The value of wildlife knowledge provided by recent migrants is less clear. Photographs of 10 mammal species were shown to 622 individuals in communities near Way Kambas National Park in Sumatra, Indonesia, to assess wildlife knowledge among recent migrants and to identify socio-economic variables that can be used to identify more knowledgeable informants. Knowledge scores were categorized by taxonomic family, genus and species. Large, charismatic and abundant animals were identified more frequently than smaller and more secretive animals. Higher knowledge scores were significantly associated with males, higher educational attainment and past experience with these animals. Number of years respondents had lived in the area and respondent age were also good predictors of higher scores. The characteristics of animals that were likely to be identified more accurately were assessed. Generic terms used to describe animals can confound individual responses. Biodiversity research, conservation and education programmes frequently rely on ‘local’ knowledge to inform management and policy. This information can be a valuable addition to field-based efforts to identify the distribution and abundance of rare endangered species. With more and more migrants living near the world's wildlife protected areas, care must be taken to understand how human demographic shifts may affect such studies.
