The rarity or absence of highly interactive species leaves a functional void that can trigger
linked changes leading to degraded or simplified ecosystems. A preliminary analysis …

Obsolescence of environmental laws and regulations is unavoidable, and policies dealing
with endangered species and ecosystem conservation often lag decades behind the …

The conservation of ecosystems focuses on evaluating individual sites or landscapes based
on their component species. To produce a map of conservation values, we developed a …

1 The level of functional redundancy in natural communities is likely to modulate how
ecosystem stability is affected by local species extinction. Thus, extinction should have no …

This book, previously published in hardback, has now been republished in paperback and
added to the growing number of titles in Chapman & Hall's Conservation Biology Series …

Human travel and transportation of goods are increas ingly changing species distributions
(Ricciardi 2007). Non-native species—those introduced beyond their nat ural ranges—often …

The functioning of the Endangered Species Act has been less effective than expected
because remedial action is not triggered until populations are in serious trouble and …

So often, the solution to a problem is overlooked because it requires a fundamentally
different way of looking at things. Once the problem is seen in a new light, the resolution is …

Preservation of wild populations implies their persistence, but biological persistence is a
relative term. This paper outlines criteria for what constitutes successful preservation and the …

Non‐native species can cause the loss of biological diversity (ie, genetic, species, and
ecosystem diversity) and threaten the well‐being of humans when they become invasive. In …
