Defaunation in the Anthropocene
Defaunation is both a pervasive component of the planet’s sixth mass extinction and also a major driver of global ecological change.
Accelerated modern human–induced species losses: Entering the sixth mass extinction
Estimates of extinction rates reveal an exceptionally rapid loss of biodiversity over the last few centuries, indicating that a sixth mass extinction is already under way and a window of opportunity is rapidly closing.
Biological annihilation via the ongoing sixth mass extinction signaled by vertebrate population losses and declines
The population extinction pulse shows, from a quantitative viewpoint, that Earth’s sixth mass extinction is more severe than perceived when looking exclusively at species extinctions and humanity needs to address anthropogenic population extirpation and decimation immediately.
Multiple ecological pathways to extinction in mammals
The results increase the understanding of extinction processes, generate simple rules of thumb that identify species at greatest risk, and highlight the potential of decision-tree analyses to inform conservation efforts.
The Prairie Dog and Biotic Diversity
Since the turn of this century, prairie dog populations have declined as much as 98% throughout North America, largely as a result of prairie dog eradication programs. The prairie dog is a keystone
Mammal Population Losses and the Extinction Crisis
Historic and present distributions of 173 declining mammal species from six continents are compared, finding that these species have collectively lost over 50% of their historic range area, mostly where human activities are intensive.
Global mammal distributions, biodiversity hotspots, and conservation
A global examination of distributions of all nonmarine mammals to determine patterns of species richness, endemism, and endangerment, and to evaluate the degree of congruence among hotspots of these three measures of diversity in mammals found it necessary to assign global conservation priorities based on hotspots.
One hundred questions of importance to the conservation of global biological diversity.
100 scientific questions that, if answered, would have the greatest impact on conservation practice and policy are identified and are expected to help identify new directions for researchers and assist funders in directing funds.
Ecosystem Services of Tropical Dry Forests: Insights from Long-term Ecological and Social Research on the Pacific Coast of Mexico
In the search for an integrated understanding of the relationships among productive activities, human well-being, and ecosystem functioning, we evaluated the services delivered by a tropical dry
Countryside Biogeography of Neotropical Mammals: Conservation Opportunities in Agricultural Landscapes of Costa Rica
The future of mammalian diversity in the tropics depends largely on the conservation value of human-dominated lands. We investigated the distribution of non-flying mammals in five habitats of
