We evaluated the relationship between amphibian and reptile diversity and microhabitat dynamics along pasture-edge-interior ecotones in a tropical rainforest in Veracruz, Mexico. To evaluate the main correlation patterns among microhabitat varia[...]

A fundamental step in conserving biodiversity is identification of quality habitat needed to sustain populations of target species. We used coarse scale environmental features (soil water holding capacity, soil texture, slope, elevation, and pro[...]

Amphibian populations have declined and disappeared in protected and apparently undisturbed areas around the world, especially in montane areas of the tropics. The amphibian chytrid fungus, Butrachochytrium dendrobatidis has been implicated in m[...]

The basking shark Cetorhinus maximus is listed as Vulnerable (A1a,d, + 2d) worldwide, and Endangered (EN Ala,d) in the north-east Atlantic in the IUCN Red List. However, protection for this species is limited in European waters and varies spatia[...]

Fragmentation of habitats has resulted in increased inbreeding for many plant species, while the introduction of foreign seed material for ecological restoration has resulted in crosses between plants from distant populations. Both processes may[...]

Sustainable use of wild populations of medicinal plants (as with other non-timber forest products) requires robust assessment of the distribution and abundance of target species. Long-term population dynamics datasets are typically unavailable i[...]

We compared species richness and abundance of birds between five patches under selective Alnus exploitation and five patches that have not been harvested for at least 10 years prior to our study, during the early dry season (April-July 2001), in[...]

In this paper, we test the hypothesis that seed rain in forest edges differs from that in forest interior in terms of seed abundance, species richness, seed size, dispersal mode, and manipulation by vertebrates. The study was carried out in the [...]

Farmers were paid to establish 6 m wide sown grass strips in arable field margins under the Countryside Stewardship Scheme in England, UK. One hundred and sixteen sites in eight regions were surveyed to determine if grass margins had been establ[...]

Reintroduction of captive animals to the wild is a conservation strategy that has rarely succeeded. For many species, the blame has been placed on ineffective post-release behavior. In particular, predation on newly released animals can be devas[...]

From 1989 to 2004, the breeding success of African penguins Spheniscus demersus at Robben Island, South Africa was significantly related to estimates of the abundance of both their main prey species, anchovy Engraulis encrasicolus and sardine Sa[...]

The wolf spider (Lycosidae) community of open paddocks and five different configurations of woodland habitat in the wheatbelt of New South Wales, Australia, was sampled by nocturnal spotlighting. A total of 16 species was detected amongst the 27[...]

Population viability analyses (PVAs) are based on basic demographic parameters such as breeding success, juvenile and adult survival. However, no PVAs have included the operational sex ratio (OSR). The Norwegian population of ortolan buntings (E[...]
