In order to gain added insight into the mechanisms of allograft destruction, skin grafts were returned to their original donors after remaining as allografts long enough to induce immunity in the intermediate host but not long enough to cause destruction of the graft. Upon their return to unmodified donors, such grafts became revascularized and remained viable. An intense cellular infiltration ...

The continuous deterioration of terrestrial ecosystems has led to the destruction many biological habitats in recent years. Tumen River cross-border basin, an important habitat, is also affected by this changing situation. Assessing habitat quality (HQ) crucial for restoring and protecting habitats, vegetation plays a significant role process. In study, we used geographical detector (GD) extrac...

-To preserve and recover evolutionarily significant units (ESUs) of anadromous salmonids Oncorhynchus spp. in the Pacific Northwest, long-term and short-term ecological processes that create and maintain freshwater habitats must be restored and protected. Aquatic ecosystems throughout the region are dynamic in space and time, and lack of consideration of their dynamic aspects has limited the ef...

Abstract Sturnira tildae de la Torre, 1959, Tilda’s yellow-shouldered bat, is a phyllostomid with wide geographic distribution across South America. It inhabits preferably lowland mature rainforests, but also has been captured in modified vegetation and tropical savannas, where it less abundant. Globally, listed as “Least Concern” (LC) by the International Union for Conservation of Nature Natur...

The first comprehensive review in five years of the world's more than 600 species of primate found that almost 50 per cent are in danger of becoming extinct, according to the criteria of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Announced at the International Primatology Congress in Edinburgh earlier this month, the report by the world's leading p...

Animal conservation requires a sound understanding of movement ecology and habitat selection. A key component this is identifying habitats that animals actively seek or avoid. We quantified selection investigated the drivers variability in short-term activity area small, endangered mesopredator, northern quoll (Dasyurus hallucatus), Pilbara region Western Australia. collated, standardised, anal...

Instream flow needs (IFN) assessment studies are performed to provide guidelines for stream water management and to assess the impacts of different water projects such as weirs, dams and stream diversions on the available fish habitat. The physical habitat simulation is one of the IFN assessment methods and also a powerful tool in management of river ecosystem that has not become a common metho...
