The Ecuadorian Chocó is a global conservation hotspot with high levels of biodiversity and endemism but is threatened by extensive deforestation. Here, we report the discovery of an additional locality for the Critically Endangered poison-dart frog

Abstract Invasive alien species are among the most pervasive threats to biodiversity. Invasive species can cause catastrophic reductions in populations of native and endemic species and the collapse of ecosystem function. A second major global conser

Global biodiversity is negatively affected by anthropogenic climate change. As species distributions shift due to increasing temperatures and precipitation fluctuations, many species face the risk of extinction. In this study, we explore the expected

Abstract Reversing large-scale habitat degradation and deforestation goes beyond what can be achieved by site-level ecological restoration and a landscape ecology perspective is fundamental. Here we assess the relative importance of tree cover and it

Choosing appropriate forest restoration interventions is challenging. Natural regeneration can rapidly facilitate forest recovery in many situations. However, barriers such as dispersal limitation and competition with non-native species can require a

Abstract Large‐seeded, animal‐dispersed (LSAD) trees include some of the most valuable and threatened species in the tropics, but they are chronically underrepresented in regenerating forests. Toucans disperse many LSAD species, so attracting tou

Abstract Applying nutrient‐rich agricultural by‐products, such as fruit peels and pulp, to degraded land has been proposed as a strategy to overcome a number of barriers to tropical forest recovery. While such linkages between agroindustry and re

Abstract Numerous countries have made voluntary commitments to conduct forest landscape restoration over millions of hectares of degraded land in the coming decade. We consider the relative likelihood these countries will achieve their restoration co

Developing rapid, cost-effective, methods to facilitate forest recovery in degraded tropical habitats is a key restoration goal. Here, we evaluated the efficacy of establishing large (≥2 m) vegetative cuttings or stakes of Ficus (Moraceae), keyston

Humans are transforming the ecology of the Earth through rapid changes in land use and climate. These changes can affect tropical forest structure, dynamics and diversity. While numerous studies have focused on diversity metrics, other aspects of for
