The endangered black-tailed dusky antechinus (Antechinus arktos) was described in 2014, so most aspects of its ecology are unknown. We examined diet composition and prey selection of A. arktos and a sympatric congener, the northern form of A. stuartii, at two sites in Springbrook National Park. Overall, taxa from 25 invertebrate orders were identified in the diets from 252 scat samples. Dietary components were similar for each species, but A. arktos consumed a higher frequency and volume of dipteran larvae and Diplopoda, while A. stuartii consumed more Coleoptera, Lepidoptera, Orthoptera and Isopoda. Both species of Antechinus had a higher percentage of ‘empty’ scats (devoid of any identifiable invertebrate material) in 2014 compared with 2015. The former was a drier year overall. Lower rainfall may have reduced abundance and diversity of arthropod prey, causing both species to supplement their diet with soft-bodied prey items such as earthworms, which are rarely detected in scats. Comparison of prey in scats with invertebrate captures from pitfall traps showed both species to be dietary generalists, despite exhibiting distinct preference and avoidance of certain prey categories. The ability of an endangered generalist marsupial to switch prey may be particularly advantageous considering the anticipated effects of climate change on Gondwanan rainforests during the mid-late 21st century.

Abstract Wildlife and ecotourism resources were assessed in and around Bale Mountains National Park (BMNP) to examine their contribution for sustainable use of natural resources which will improve the livelihood of local communities and conservation of park. Survey questionnaires, interview, field observation and literature reviews were employed to collect primary and secondary data. The analyses of the study revealed that natural and cultural resources such as abundance and diversity of mammals and birds, scenic landscape, cultural and historical attractions and some hotels or lodges at nearby areas are the main ecotourism potential in BMNP. The study also revealed some income generating alternatives or ecotourism potentials which could help to reduce the present degradations of natural resources of the park. About 37.2% of sampled households expressed their interests for diversified livelihood or ecotourism activities. Offering tourist facilities and services and creating job opportunities for members of local communities are the positive impacts of the tourism activities whereas, cutting trees, occurrences of seasonality and leakages are the negative impacts. Reinforcing existing off-agricultural livelihoods, introducing additional alternative options or ecotourism are important strategic directions for sustainable management of natural resources for BMNP and related protected areas.

Level Monitoring

Monitoring is a vital component of keeping protected areas in desired states. Lack of robust designs, however, impedes efficient monitoring. We ask two questions—how does effort at a specific site as well as number of sites in a plant community influence richness, abundance, and diversity indicators. Large mammal herbivory biodiversity influences are a key concern for managers of Mokala National Park. We anticipated that changes in biodiversity indicators (vegetation, ants, and birds) associate with herbivore intensity of use of landscapes. We identified flat deep sandy plains and undulating shallow rocky hills as focal landscapes. Our focus was on finding optimized effort at survey sites as well as the number of sites. Monitoring to evaluate change in diversity and abundance needs far less effort than evaluating change in richness. Furthermore, given the variance at the landscape level, monitoring of species abundance and diversity allows easier detection with less effort and at shorter intervals between surveys than that required for richness. Even though a mechanisms-based approach directs monitoring, conservationists need to evaluate feasibility. In our case, measurement of richness is unlikely to detect herbivore effects. In general though, we have illustrated that focused monitoring designs can robustly evaluate conservation objectives.

Butterflies are insects that have very important role in the ecosystem, they are as a pollinator of plants. Butterfly also can be used as a bio-indicator of environmental quality. This study aims to determine the species abundance and diversity of butterflies in the area of Merbabu Mountain National Park. This research was conducted in September and November 2016 in four habitat types, i.e., mixed forests, pine forests, mountain forests and streams. The study was conducted using a purposive sampling method. The data analysis used abundance index and diversity index. There are 454 individuals wich includes 61 species and 6 families. There are 11 dominant species of butterflies in Merbabu Mountain National Park, but only Ypthima pandocus that dominates in all the habitat that studied. Mycalesis moorei and Mycalesis sudra are dominant in all forest habitats and its not dominant in the habitat of the streams. Papilio peranthus and Parantica albata are dominant and only in mountain forest habitat. Diversity of butterflies in the area of Merbabu Mountain National Park can be categorized as moderate with the diversity index from 2,11 – 3,37. Key word: Butterflies, diversity, abundance, Merbabu Mountain National Park

Abstract Species diversity can be affected by the structure of vegetation, which may vary in height, density, and distribution of trees, shrubs, and other plant types, configuring different types of habitats. In this study, we evaluated the diversity of sarcosaprophagous Sarcophagidae communities inhabiting the remnant representative habitats protected in Ciervo de los Pantanos National Park: grasslands, forests, and wetlands. We hypothesized that the abundance and diversity of flesh flies would be higher in the grasslands and wetlands than in the forest patches. Samplings were carried out in each habitat type using baited traps during the four seasons in 2015, 2016, and 2019. We collected 585 sarcophagid flies of 17 species. Fifteen species were recorded in grasslands, twelve in the wetlands, and seven in the forests, Tricharaea (Sarcophagula) occidua (Fabricius) (Diptera: Sarcophagidae) being the most abundant (58.3% of the total sample). As expected, the highest abundance was recorded in grasslands whereas the lowest was found in forests. In addition, flesh fly abundance was affected by season. Sarcophagid assemblages differed between habitats and the overall dissimilarity was mainly explained by nestedness. This study provides important information about sarcosaprophagous sarcophagid flies in a little-studied protected natural area in Argentina, which is fundamental for their conservation and useful in forensic investigations.

Abundance And Diversity

We documented abundance and diversity of raptors in a relatively undisturbed landscape in Grand Teton National Park, Wyoming, from February through August 2002. Within a 31.1 km2 study area we located 46 nesting pairs that consisted of 9 raptor species. The American kestrel (Falco sparverius) and the Common raven (Corvus corax) were the two most abundant species on the study area. We considered Common ravens as an ecological and trophic level equivalent of raptors. Six of nine species fledged at least one young, and the mean number of young fledged per occupied nest for all species was 1.0 (sd = 1.0, range = 0 to 3.0). We observed complete nesting failure for Swainson's hawks (n=4 nests), Bald eagle (n=1 nest), and the Long-eared owl (n = 1 nest). We located the territory but not a nest for two Great horned owl (Bubo virginianus) adults, and two Sharp-shinned hawk adults. Six of the nine species observed in 2002 migrate, and two of the nine species are known neotropical migrants. Cold and wet weather conditions along with a high wind storm during the early incubation period appeared to have a negative effect on the breeding success of stick-nest breeders on the study area.

Autumn And Winter

 In autumn and winter, 24 migratory waterfowl species from the north utilise the wetlands of Chitwan National Park, which provide vital staging, roosting, resting, foraging and breeding places. The birds stay for about eight months before returning north in March and April. These birds are indicators of healthy wetlands, and they distribute nutrients through their droppings that increase primary production of aquatic vegetation and fish. A population census of wetland birds was conducted during January 2014 in Chitwan National Park on the Rapti and Narayani rivers and associated wetlands, including Lami Tal, Tamor Tal, Garud Tal, Devi Tal and marshes and lakes around Temple Tiger. The study found that the Ruddy Shelduck Tadorna ferruginea was the migratory waterfowl with the largest population in these rivers.
