We tested the hypotheses that species with greater mobility and/or higher reproductive rates are less sensitive to habitat loss than species with lower mobility and/or reproductive rates by conducting a meta-analysis of wetland vertebrate responses to wetland habitat loss. We combined data from 90 studies conducted worldwide that quantified the relationship between wetland amount in a landscape...

Point Pelee National Park, located at the southern-most tip of Canada's mainland, historically supported a large number of herpetofauna species; however, despite nearly a century of protection, six snake and five amphibian species have disappeared, and remaining species-at-risk populations are thought to be in decline. We hypothesized that long-term changes in availability and distribution of c...

As deforestation frontiers expand in the tropics, understanding species responses is critical to inform efficient land-use management policies. Here we evaluated lizard changes landscape, habitat patch, and quality a frontier southwestern Brazilian Amazonia. We first considered overall assemblages then two subgroups of contrasting thermoregulation strategies. sampled lizards at 21 forest patche...

Habitat restoration is a key management strategy for species that experience loss, fragmentation or degradation of their habitat. The St. Francis’ satyr is a federally endangered butterfly found only on Ft. Bragg Army Installation in North Carolina that depends on frequent disturbance to maintain its preferred habitat, ephemeral wetlands. Over the course of 4 years, we restored and maintained c...

The effects of habitat loss and fragmentation on the genetic structure and vulnerability of populations strongly depend on the behaviour of a particular species. In this thesis, I examined the effects of forest fragmentation on genetic population structure with the aim of identifying and evaluating the different genetic and behavioural factors important for species conservation and management o...

Please cite this article in press as: Visconti, P., et persistence. Biol. Conserv. (2010), doi:10.1016/j Conservation actions frequently need to be scheduled because both funding and implementation capacity are limited. Two approaches to scheduling are possible. Maximizing gain (MaxGain) which attempts to maximize representation with protected areas, or minimizing loss (MinLoss) which attempts ...
