Abstract It is becoming increasingly evident that many species can tolerate different degrees of habitat perturbation and that we often underestimate the capacity of some human-modified landscapes to support populations of declining species. We provide new insights into the distribution of the endangered Central American squirrel monkey and habitat changed over the last 20 years. The species has shown an approximate 60% decrease between the historic and the present extent of occurrence, with an ...

Tropical agriculture is a major driver of biodiversity loss, yet it can provide conservation opportunities, especially where protected areas are inadequate. To investigate the long-term biodiversity capacity of agricultural countryside, we quantified bird population trends in Costa Rica by mist netting 57,255 birds of 265 species between 1999 and 2010 in sun coffee plantations, riparian corridors, secondary forests, forest fragments, and primary forest reserves. More bird populations (69) were d...

The environmental sciences have documented large and worrisome changes in earth systems, from climate change and loss of biodiversity, to changes in hydrological and nutrient cycles and depletion of natural resources (1⇓⇓⇓⇓⇓⇓⇓⇓⇓⇓–12). These global environmental changes have potentially large negative consequences for future human well-being, and raise questions about whether global civilization is on a sustainable path or is “consuming too much” by depleting vital natural capital (13). The incre...

Scientific misunderstanding about the nature and consequences of the sixth mass extinction has led to confusion among policy-makers and the public. Scientists agree that there have been five mass extinctions in the past 600 million years ([ 1 ][1]). Although scientists also agree that Earth is now
