Poaching of elephants is now occurring at rates that threaten African populations with extinction. Identifying the number and location of Africa's major poaching hotspots may assist efforts to end poaching and facilitate recovery of elephant populations. We genetically assign origin to 28 large ivory seizures (≥0.5 metric tons) made between 1996 and 2014, also testing assignment accuracy. Results suggest that the major poaching hotspots in Africa may be currently concentrated in as few as two areas. Increasing law enforcement in these two hotspots could help curtail future elephant losses across Africa and disrupt this organized transnational crime. © 2015, American Association for the Advancement of Science.

The Rhino have existed on top of the globe intended for more than 40 million years and contain a wonderful record. The surviving Rhinos are precious representatives of the splendid heritage and history of the Rhino family unit taking place our earth. The viable utilization of Rhinos in Africa as well as Asia is immobile ongoing as this animal carries horn appeal its worth akin to gold. Seeing as last 35 years poaching has caused death of a lot of Rhino into this earth and has show the way every one the species of Rhino into struggle for existence. According to the CITES the three of the five species, the black rhino(Diceros bicornis), Javan rhino (Rhinoceros sondaicus), Sumatran rhino (Dicerorhinus sumatrensis) are slowly and steadily becoming critically endangered. Presently the black rhino and white rhino are two of the most charismatic mega herbivores left on our planet and have became the flagship species of International conservation. The greater one-horned rhinoceros (Rhinoceros unicornis), scheduled as endangered species by IUCN and on Appendix I of CITES, has now been cramped hooked on a small number of confined populace adding together about 3000 animal in several parks in India and Nepal. At present Kaziranga National Park ( KNP), Assam is a significant conservation values of world's largest Indian or greater One-horned Asian rhinoceros. Asiatic wild buffalo and Eastern Swamp deer population. Subsequent to concerning 100 years of protection, the Kaziranga at the present hold up a possible population of 2329 rhinos by means of 5.65% an animal increase rate . The usual density of the rhino is 3.65/sq.km with highest density of 9.25rhinos/sq.km. in the western range of KNP. The populace of one rhino into the appearance two-third of their whole populace within the entire earth. According to specialist the bulk of tigers at Kaziranga is 32.64 tigers for each 100 sq.km. The uppermost into several know tiger habitat. Kaziranga is one of the main territory of protected terrain in the sub-Himalayan girdle, and owing in the direction of the company of extremely assorted and noticeable species, has been described as a "biodiversity hotspot". The Park has been complete and intended by means of divide national park rank to make available comprehensive environment for increasing the population of wildlife or, as a corridor for secure association of animals to Karbi Anglong Hills. The park is situated in the Indomalaya ecozone, and the most important biomes of the region are Brahmaputra Valley semi- evergreen forests of the tropical and subtropical mist broad leaf forests biome and a regularly flooded alternative of the Terai-Duar savanna and grasslands of the tropical and subtropical grasslands savannas, and shrub lands biome. The Park has been shaped by means of alluvial deposit of Brahmaputra river and is a assortment of grasses interspersed by means of tropical wet evergreen and semi-evergreen forests and beels which create the area appropriate for rhino. Poaching , Erosion, encroachment, flood, siltation and Invasive species, however, are the major problems in Kaziranga's one -homed rhinoceros conservation. This paper aim of this arrangement is to evaluate the present condition of inhabitants, surroundings and conservation problems and to build up a comprehensive plan intended for the upkeep and management of rhino eternity.

Aim: To understand the relative importance of ecological and biogeographical processes structuring assemblages of Himalayan leaf warblers (family Phylloscopidae), through an evaluation of (1) the patterns of species richness and phylogenetic community structure, (2) their environmental determinants, and (3) dispersion of morphological traits within communities. Location: Elevational gradients across the east and the west Himalayas, India. Methods: Species presences were assessed at 16 sites along eight elevational gradients. Phylogenetic conservatism was assessed in three functional morphological traits (body size, tarsus length, beak shape) and phylogenetic structure in terms of the net relatedness index (NRI) was quantified using a published phylogenetic tree. Site-specific species richness and NRI were related to climatic variables and arthropod abundance. Morphological trait metrics were also calculated and the observed trait dispersion related to patterns of species richness and phylogenetic structure of the assemblages. Results: The 16 assemblages, composed of two to eight species, ran the entire spectrum of significance in terms of their phylogenetic structure, resulting in many clustered assemblages at low elevations and a few overdispersed assemblages at higher elevations. Phylogenetic structure was not significantly correlated with species richness, although variation in both was largely explained by maximum temperature and arthropod abundance. At the regional scale, both trait filtering (beak shape) and trait convergence (tarsus length) seem to influence the distribution of species along the elevational gradients. Dispersion of body size metrics suggested filtering and competition as predicted by phylogenetic structure, while beak shape metrics suggested competitive interactions even in phylogenetically clustered assemblages. Main conclusions: The interaction of multiple assembly processes (competition, filtering and history) appears to structure the Himalayan leaf warbler assemblages. Phylogenetic community structure largely reflected the biogeographical history of species accumulation into the Himalayas, while processes structuring local assemblages were better explained by the dispersion of traits. © 2014 John Wiley & Sons Ltd.

The idea that ecological communities are unsaturated is central to many explanations for regional gradients in species diversity. We describe a test for differing degrees of saturation across a regional diversity gradient, based on within-species geographical variation in ecological attributes. If communities in species-poor regions are less saturated than communities in species-rich regions, species that straddle both regions should have broader niches in species-poor regions, exploiting resources that are consumed by other species in species-rich regions. We studied 10 species of Old World leaf warblers that range across the Himalayas. Elevational range and feeding method showed niche contractions in the species-poor north-west Himalayas with respect to the species-rich south-east Himalayas, whereas prey size did not vary geographically. Niche contractions are contrary to the expectation of character release in depauperate environments, as has been shown, for example in mainland-island comparisons. We show that arthropod abundances are likely a limiting resource, and that niche contractions are consistent with measurements of a narrowing of resource availability. Results suggest that north-western warbler communities are at least as saturated as the south-east and that lower resource diversity drives reduced species numbers. © 2013 British Ecological Society.

The resurrection of Asiatic lions (Panthera leo persica) from the brink of extinction is a remarkable conservation success story. Yet, occurrence of lions as a single population makes them vulnerable to extinction from genetic and environmental factors. Asiatic lions exist as a single free ranging population of 360 individuals in Gir Protected Area (PA; about 290 lions) and surrounding satellite areas (68 lions), namely Girnar Wildlife Sanctuary (WLS), coastal areas, hill ranges extending from Mitiyala-Savarkundla-Palitana-Shihor spreading across Junagadh, Amreli and Bhavnagar districts of Gujarat State, India. This paper traces the conservation history, current conservation pressures, and critically evaluates current conservation planning based on lion ecology and existing anthropogenic pressures. Conservation proposals for translocation of lions to alternate habitats in Kuno WLS and Barda WLS are awaiting final implementation. An alternate initiative is aimed at developing satellite lion habitats, improving corridor connectivity, and facilitating natural dispersal and expansion of lion habitats. The paper evaluates human population living within 2 km boundary of lion habitats and between Gir PA and satellite habitats to show that dispersing lions have to cross heavily populated habitations taking refuge in agriculture fields and scattered forest patches. Satellite habitats vary in size from 18 km2 (Mitiyala WLS) to 250 km2 (scattered forests Hipavadli-Savarkundla-Palitana zone along Shetrunji river) and are inadequate to maintain natural ranging and movement requirements of territorial lions. These habitats are varied in vegetation, terrain, human pressure, and distance to source population. Though satellite lion habitats are important suboptimal habitats for dispersing lions, long-term conservation planning require planned restoration of mosaic habitats for growing populations. © Springer-Verlag 2009.
