Much of the biodiversity associated with isolated wetlands requires aquatic and terrestrial habitat to maintain viable populations. Current federal wetland regulations in the United States do not protect isolated wetlands or extend protection to surrounding terrestrial habitat. Consequently, some land managers, city planners, and policy makers at the state and local levels are making an effort ...

and/or keywords. This search revealed a total of 227 papers. We randomly selected 100 of these papers and identifi ed the ways in which habitat fragmentation effects are being assessed. Evaluating and Measuring Habitat Fragmentation Habitat may be broadly defi ned as “the range of environments suitable for a given species” (Hall et al. 1997 ). For primates this generally refers to broad vegetat...

Partial brood loss in red-cockaded woodpeckers (Picoides borealis) was studied during 2 breeding seasons in eastern Texas. The timing of partial brood loss, group size, number of initial nestlings, number of birds fledged, and habitat characteristics of the group's cavity-tree cluster were examined for 37 woodpecker groups in loblolly(Pinus taeda) shortleaf (I! echinata) pine habitat and 14 gro...

Plant and animal population sizes inevitably change following habitat loss, but the mechanisms underlying these changes are poorly understood. We experimentally altered habitat volume and eliminated top trophic levels of the food web of invertebrates that inhabit rain-filled leaves of the carnivorous pitcher plant Sarracenia purpurea. Path models that incorporated food-web structure better pred...

Habitat loss and climate change both kill off species. New studies show that the latter is a potent threat. Worse, its victims will likely be mostly those not presently threatened by habitat loss.

Fish habitat loss has been prevalent over the last century in Canada. To prevent further erosion of the resource base and ensure sustainable development, Fisheries and Oceans Canada enacted the habitat provisions of the Fisheries Act in 1976. In 1986, this was articulated by a policy that a "harmful alteration, disruption, or destruction to fish habitat" (HADD) cannot occur unless authorised wi...
