We live amid a global wave of anthropogenically driven biodiversity loss: species and
population extirpations and, critically, declines in local species abundance. Particularly …

In this Analysis we use published 16S ribosomal RNA gene sequences to compare the
bacterial assemblages that are associated with humans and other mammals, metazoa and …

The population extinction pulse we describe here shows, from a quantitative viewpoint, that
Earth's sixth mass extinction is more severe than perceived when looking exclusively at …

Land free of direct anthropogenic disturbance is considered essential for achieving
biodiversity conservation outcomes but is rapidly eroding. In response, many nations are …

Because habitat loss is the main cause of extinction, where and how much society chooses
to protect is vital for saving species. The United States is well positioned economically and …

Identifying priority areas for biodiversity is essential for directing conservation resources.
Fundamentally, we must know where individual species live, which ones are vulnerable …

Inadequate funding levels are a major impediment to effective global biodiversity
conservation and are likely associated with recent failures to meet United Nations …

Endemism and species richness are highly relevant to the global prioritization of
conservation efforts in which oceanic islands have remained relatively neglected. When …

Knowledge of mammalian diversity is still surprisingly disparate, both regionally and
taxonomically. Here, we present a comprehensive assessment of the conservation status …

The vast scope of conservation problems has forced biologists and managers to rely on"
surrogate" species to serve as shortcuts to guide their decision making. These species …
