Although human-driven landscape modification is generally characterized by habitat destruction and fragmentation, it may also result in the creation of new habitat patches, providing conditions conducive to spontaneous colonization. In this article, we propose the concept of "colonization credit" (i.e., the number of species yet to colonize a patch, following landscape changes) as a framework t...
The habitat destruction and land-use changes caused the decline of animal composition in many tropical regions. Here, we study diversity herpetofauna lowland areas Sumatera Barat, a midwestern province island, using visual encounter survey method. surveyed included rubber plantations, streams, paddy fields, peat swamps. We observed 338 individuals representing 44 species from 14 families with a...
BACKGROUND The potential for reduced pollination ecosystem service due to global declines of bees and other pollinators is cause for considerable concern. Habitat degradation, destruction and fragmentation due to agricultural intensification have historically been the main causes of this pollinator decline. However, despite increasing and accelerating levels of global urbanization, very little ...
In biodiversity conservation, habitat corridors are assumed to increase landscape-level connectivity and to enhance the viability of otherwise isolated populations. While the role of corridors is supported by empirical evidence, studies have typically been conducted at small spatial scales. Here, we assess the quality and the functionality of a large 95-km long forest corridor connecting two la...

Indian Pangolin (Manis crassicaudata) represents the world’s most trafficked and highly threatened species due to poaching habitat destruction (Newton et al., 2008). In India, two of Pangolin; crassicaudata), also called thick-tailed Chinese pentadactyla), are distributed throughout country except for Trans-Himalayan region (Mahapatra 2015). The remains endangered by IUCN (Mahmood 2019) Appendi...
Conservation of habitat for flagship species, such as birds, aids in the protection of biodiversity in critical ecosystems. Extensive mats of macroalgae stimulated by nutrient input to estuaries threaten critical successes in conservation made by legislation that reduces habitat destruction. Macroalgae can cover intertidal mudflats that are key foraging grounds for obligate visual foragers such...
