The Red fox (Vulpes vulpes) is a least concern carnivore according to the IUCN Red List of Threatened Species (2016). However, in Pakistan Red fox is considered as Near Threatened (NT), due to habitat destruction and depletion of food resources. The objective of the study was to identify habitat preferences and population density of Red fox in District Chakwal, Pakistan. Line transect census method was used to estimate the population density of Red fox through direct sighting and indirect method of burrow counting, presence of footprints and scats. A total of 10 transects were carried out at three potential sites: Devi, Photaki and Chumbisurla Wildlife Sanctuary (CWS) in Chakwal based on preliminary surveys. Habitat preference was estimated by comparing three different study sites by quadrat method and found that CWS area is preferred habitat for Red fox. A total of 24 plant species were recorded in the study areas, among them Cynodon dactylon is major herb found to provide shelter to Red fox in all study sites based on Importance value Index (I.V.I) at CWS (IVI=208.8) followed by Devi (IVI=185.93) and Photaki (IVI=142.33). The maximum population density of Red fox through direct sighting at CWS having 0.26 individuals/km2 compared to Devi and Photaki having 0.16 and 0.13 individuals/km2, respectively. The indirect estimation method revealed that maximum dens were found in CWS area compared to Devi and Photaki, while footprints and scats were found maximum in Devi and Photaki, respectively. It is concluded that Red fox preferred habitat is CWS site. Habitat destruction and conflicts with fox are causing the population of the Red fox to dwindle in Chakwal, Pakistan.

Himalayan or White-bellied Musk Deer Moschus leucogaster, an IUCN indexed endangered species, is distributed in isolated pockets in the Himalaya. The deer population is decreasing owing to several pressures that include habitat loss and fragmentation, and poaching. It is essential to identify preferred habitat characteristics to support appropriate management strategies for conserving this endangered species. This study was carried out in the Nysheang basin of Annapurna Conservation Area of Nepal to identify habitats preferred by the musk deer. Habitat field parameters were collected using transect surveys. To analyze vegetation use and availability, nested quadrate plots size 20 m2 were established. Ivlev’s electivity index (IV) (-1 to +1) was employed to determine habitat preference, and one-way ANOVA (F) and chi-square tests (χ2) were used to examine different habitat parameters. Similarly, the importance value index (IVI) of the vegetation was calculated. Our results showed that the Himalayan Musk Deer strongly preferred habitats at 3601–3800 m altitude (IV= 0.3, F= 4.58, P <0.05), with 21–30º slope (IV= 0.2, F= 4.14, P <0.05), 26–50 % crown cover (IV= 0.25, F= 4.45, P <0.05), 26–50 % ground cover (IV= 0.15, F= 4.13, P <0.05), and mixed forest (IV= 0.29, χ2= 28.82, df= 3, p <0.001). Among the trees, Abies spectabilis (IVI= 74.87, IV= 0.035) and Rhododendron arboretum (IVI= 55.41, IV= 0.02) were the most preferred, while Rhododendron lepidotum, Cassiope fastigiata (IV= 0.35) and Berberis aristata (IV= 0.25) were the most preferred shrubs, and Primula denticulata (IV= 0.87) and Primula rotundifolia (IV= 0.31) were the most preferred herbs. These preferred habitat conditions should be maintained and conserved to sustain a viable population of deer in the study area. Further studies will be required to assess the effects of climate change on habitat suitability.

AbstractWe conducted a survey of the distribution and population status of the eastern hoolock gibbon Hoolock leuconedys in non-protected fragmented forest areas of the Lower Dibang Valley district of Arunachal Pradesh, India, during September 2010–June 2011. We estimated the minimum population density at seven study sites by direct observation and by counting the number of vocalizations heard from groups that were out of view. We used 1-ha belt transects (500 × 20 m) to estimate tree diversity in the study area. For two groups of gibbons we recorded their feeding patterns in forest fragments, using focal individual sampling, during May 2011. A total of 54 groups and three solitary individuals were recorded: 39 groups and three individuals through visual encounter and 15 groups through vocalization recognition. The mean group size recorded was 2.89 ± SE 0.11 (range 2–4). We counted a total of 289 trees, of 26 species and 17 families, in 18 belt transect surveys covering all non-protected fragments of the Lower Dibang Valley district. The gibbons' diet consisted of seasonal fruits and figs (29%), leaves (65%), seeds (2%) and flowers (0.5%). The major threats recorded at the study sites were habitat destruction and hunting. To protect the Vulnerable eastern hoolock gibbon, conservation measures will need to involve local communities.

The human ativities of macroalgae utilization, land conversion, and sea transportation can cause of macroalgae biodiversity decline. The purpose of this study was to analyze the structure and distribution of macroalgae in seagrass ecosystems at South Tabukan District, Sangihe Islands Regency, North Sulawesi. The research locations were at three research stations, i.e. Karurung Beach - Salurang Village, Palareng Beach - Palareng Village and Galoghong Beach - Batuwingkung Village. The study was conducted in November-December 2018 with line transect method sampling and quadrate sampling technique. Macroalgae were 36 species consists of 25 species of Chlorophyta Division, nine (9) species of Rhodophyta Division and two (2) species of Phaeophyta Division. Macroalga Bornetella nitida had Importance Value Index 39.24% that dominated research locations. The Shannon-Wiener biodiversity Index (H’) of macroalgae species at Station I (H': 3.02) was classified as high while Station II (H': 2.86) and Station III (H ': 2.63) were moderate. Overall, macroalgae species diversity at Tabukan Selatang District was high (H’: 3.00).
