Toward a functional understanding of novel fire regimes in tropical forests. [PDF]
Abstract Climate change and land‐use alterations are driving forest fires to unprecedented frequencies and intensities worldwide. Even wet tropical forests—historically rarely subjected to fire—are increasingly experiencing fire disturbances. The impact of wildfires on these forests is likely large, since many of their tree species are not adapted to ...

Resource suitability drives low use of avian-excavated tree cavities: A multi-state occupancy dynamics approach. [PDF]
Birds that nest in tree cavities are sometimes dependent on a few cavity‐excavating bird species to make nesting sites available. Such interdependency, however, does not always materialize because excavated cavities may be unsuitable for continued use, even when available for several years after excavation.

Effects of seagrass restoration on coastal fish abundance and diversity
Abstract Restoration is accelerating to reverse global declines of key habitats and recover lost ecosystem functions, particularly in coastal ecosystems. However, there is high uncertainty about the long‐term capacity of restored ecosystems to provide habitat and increase biodiversity and the degree to which these ecosystem services are mediated by ...

Abstract Invasive species can dramatically alter ecosystems, but eradication is difficult, and suppression is expensive once they are established. Uncertainties in the potential for expansion and impacts by an invader can lead to delayed and inadequate suppression, allowing for establishment.

Abstract Africa's protected areas (PAs) are the last stronghold of the continent's unique biodiversity, but they appear increasingly threatened by climate change, substantial human population growth, and land‐use change. Conservation planning is challenged by uncertainty about how strongly and where these drivers will interact over the next few decades.

Abstract Rich in raw materials, the state of Guerrero, Mexico, is one of the main enclaves of opium production, mineral extraction, and a focus for the multiplication of armed actors in Latin America, which, together with the overlapping of counterinsurgent violence in the past, post‐colonial violence and the militarization of the policies of the so ...

Time‐lagged effects of habitat fragmentation on terrestrial mammals in Madagascar
Abstract Biodiversity is severely threatened by habitat destruction. As a consequence of habitat destruction, the remaining habitat becomes more fragmented. This results in time‐lagged population extirpations in remaining fragments when these are too small to support populations in the long term.

We use model projections to explore the timing and intensity in the distribution of marine fish stocks that are shared across the world's Exclusive Economic Zones (EEZ). Our findings suggest that many shared stocks’ distribution and catch are expected to change in most EEZs by 2030.
