Understanding the causes, processes and ecological consequences of land use change is a conservation priority in fragmented, human dominated landscapes but is often difficult due to insufficient environmental and social data or data at different[...]

Anthropogenic habitats can offer opportunities for expansion of rare species. The federally listed herb Hypericum cumulicola is virtually restricted to natural gaps within fire-maintained Florida scrub, but also occurs within and along sandy roa[...]

In the selection of reserve networks there are special sites whose ecologic, strategic or morphologic values dictate their inclusion. The existence of regional rare or confined-distribution species is one among other reasons that often determine[...]

Introduction of non-indigenous species can alter marine communities and ecosystems. In shellfish farming, transfer of livestock, especially oysters, is a common practice and potentially constitutes a pathway for non-indigenous introductions. Man[...]

We explored the extent of interspecific hybridisation between alien and native plant species in Germany with a special focus on the potential threat for native biodiversity. In total we listed 134 hybrids which are interpreted as products of hyb[...]

Cambodia forms part of the Indo-Burma hotspot. Its extent of biodiversity, however, is subject to considerable uncertainty, as there has been little systematic collection of flora and fauna. During the Khmer Rouge regime institutions were banned[...]

Many European blanket mires are degraded and contain few Sphagna. In Wales, more than half exhibit symptoms of degradation. We used palaeoecological techniques to chronicle recent vegetation history at two upland localities in South Wales to pro[...]

Staphylinid beetle assemblages from coniferous foothills forest in west-central Alberta, Canada were studied via pitfall trapping to examine the effects of stand age and possible edge effects. Sites included a chronosequence of stands from 1 to [...]

Supportive breeding is an important tool in conservation management, but its long-term genetic consequences are not well understood. Among the factors that could affect the genetics of the offspring is sperm competition as a consequence of mixed[...]

Animals use environmental cues, social information and behavioural decision-making rules moulded by natural selection to decide where to breed. We assessed whether the presence of an alien nest predator, the Black Rat (Rattus rattus) is used by [...]

The Balearic shearwater Puffinus rnauretanicus is one of the most critically endangered seabirds in the world. The species is endemic to the Balearic archipelago, and conservation concerns are the low number of breeding pairs, the low adult surv[...]

The primary goals of marine reserves include protecting biodiversity and ecosystem structure. Therefore, a multispecies approach to designing and monitoring reserve networks is necessary. To gain insight into how the interactions between species[...]

Extinction risk is not evenly distributed among all species. Therefore, identifying shared characteristics of species that have shown serious population declines and range contractions can help to predict which types of species are likely to be [...]
