The recent rediscovery of the polecat (Mustela putorius) in Scotland has raised the question of whether the species has been present at low abundance all along or was covertly reintroduced. We assess the exceptionality of the recent sighting. Th[...]

Hector's dolphin Cephalorhynchus hectori is found only in New Zealand waters. We carried out a population survey of the North Island subspecies Cephalorhychus hectori maui, also known as Maui's dolphin. The total population size estimate is ill [...]

Butterflies and burnet moths are a suitable model species group with which to analyse the general decline of invertebrate biodiversity over the last few decades. in this study, we analysed which ecological groups of butterflies and burnet moths [...]

In contrast to many other western European countries, the knowledge about trends in the Swedish butter-fly fauna is poor. We studied the effects of habitat and species characteristics on species turnover in 13 grassland sites in southern Sweden [...]

Harvest records reveal that populations of bobcats (Lynx rufus) in New Hampshire have undergone substantial changes during the past 200 years. In the 1800s, a nearly continuous bounty program resulted in annual harvests that averaged similar to [...]

Gould's petrel (Pterodroma leucoptera leucoptera) was restricted, essentially, to a single breeding locality - Cabbage Tree Island, Australia. As a safeguard against extinction, an additional breeding colony was established on nearby Boondelbah [...]

A basic assumption in conservation is that comparable data are available for species to facilitate risk assessment of extinction. However, the capacity for carrying out cross-species comparisons for abundances and distributions among butterflies[...]

Most large mammalian carnivores are in global decline, largely due to their involvement in livestock depredation. Research that advances our understanding of predator-livestock interactions is crucial to conflict mitigation and carnivore conserv[...]

Research has shown that avian malaria plays an important role in limiting the distribution and population sizes of many Hawaiian birds, and that projected climate change is likely to eliminate most disease-free habitat in Hawai'i in the next cen[...]

Community Based Wildlife Management (CBWM) has been suggested as a conservation strategy in response to bushmeat hunting in the Udzungwa Mountains within the Eastern Afromontane biodiversity hotspot. The feasibility of CBWM based on meat croppin[...]

North American beavers (Castor canadensis) were introduced into southern South America in 1946. Since that time, their populations have greatly expanded. In their native range, beavers shape riparian ecosystems by selectively feeding on particul[...]

Native plants in gardens can potentially aid conservation by contributing to genetic diversity and buffering small and otherwise isolated populations from extinction. However, gene flow from such plantings may threaten the genetic integrity of n[...]

Throughout North America, bird population declines may be attributable to loss of habitat on the breeding grounds. Human land uses such as residential development, greatly impact landscapes and biota, particularly breeding birds. Riparian areas,[...]
