The relocation and resettlement of people from nature reserves is a controversial issue in the conservation community. The perceived poor success rate of resettlement efforts, combined with availability of few well-documented studies, warrants a[...]

Transferring plants between populations of rare species has often been proposed to increase population size and replenish genetic variation. While this approach has many advantages, it may also disrupt local adaptation. However, the scale over w[...]

A common issue faced by fisheries and marine protected species managers is how to estimate the potential impacts of bycatch and identify appropriate options for mitigation, in the absence of quantitative data. This problem formed the basis to a [...]

An integrative approach to managing host-parasite interactions that threaten species communities will benefit from identifying variation in parasite impact across host species, and host-parasite responses to annual climatic variation. We examine[...]

Assessing the impact of habitat fragmentation has become a central issue in conservation biology. Ecologists are urged to document and predict the ability of species to maintain viable populations in fragmented areas. Rarity in fragments is comm[...]

Invasive non-native species are one of the main threats to biodiversity. Consequently there is a need to control or eradicate those species that are causing problems in order to mitigate their impact. Such management programmes can be controvers[...]

The spatio-temporal dynamics of amphibian populations and the models that describe them are largely influenced by the frequency of dispersal among breeding sites; however, dispersal has rarely been addressed rigorously in empirical studies. In a[...]

Species rich semi-natural grasslands are an important but threatened habitat throughout Europe and much of the former area has been lost since the 1950s. However, in some countries large areas have been preserved and the demand for meadow recrea[...]

This paper documents the emergent snake 'fishery' occurring on Tonle Sap Lake where an estimated 6.9 million snakes (mostly homalopsids) are removed annually, representing the world's largest exploitation of a single snake assemblage. Based on i[...]

In fragmented landscapes, tree recruitment is critical for forest persistence. We examined the effects of disturbance and environmental factors, isolation distance, and forest area on the spatial scale (grain) of regeneration of tree species in [...]
