Protection status and environmental gradients shape butterfly assemblages in an East African tropical ecosystem

Insect Conservation and Diversity, EarlyView.
Observed butterfly richness was highest in moderately protected areas. During the dry season, vegetation productivity increased butterfly richness while human population density reduced it. Moderately protected areas supported high butterfly abundance and a high proportion of host‐specialist species.

Fire‐driven forest degradation enhances termite activity and accelerates litter decomposition in the Amazonia rainforest

Insect Conservation and Diversity, EarlyView.
Forest degradation increased termite‐mediated litter decomposition, whereas no such effect was detected in undisturbed forests. Reduced ant predation and altered forest conditions were associated with higher termite abundance and faster litter decomposition.

The Landless Rural Workers Movement (MST) and New Agrarian Questions in Brazil

Journal of Agrarian Change, EarlyView.
ABSTRACT The Landless Rural Workers Movement of Brazil (MST) primarily organized occupations of large‐scale farms, forcing the redistribution of land for creation of agrarian reform settlements. In the past 20 years, however, land occupations and the establishment of new agrarian reform settlements have consistently declined, while the MST shifted ...

Occurrence and distribution of sarcoptic mange in wild Neotropical canids

Medical and Veterinary Entomology, EarlyView.
Sarcoptic mange affects most Neotropical canid species across multiple countries. It represents a widespread yet largely overlooked conservation threat with potential for cross‐species transmission. Coordinated monitoring and management efforts are needed to understand and mitigate its impacts. Abstract Sarcoptic mange, a contagious skin disease caused

Floral intra‐individual variation differs between morphs and is linked to pollen deposition in self‐incompatible distylous plants

Plant Biology, EarlyView.
For most traits, floral intra‐individual variation was similar between morphs and populations with different pollinator guilds (bees and hummingbirds), potentially facilitating effective pollen transfer in distylous systems. Still, greater variation in corolla length increased pollen deposition in L‐morph flowers in the bee‐pollinated population ...

Ecosystem diversity in African savannas is fueled by pyrodiversity

Abstract African savannas are experiencing a rapid decline in burned area, often entailing a simplification of landscape pyrodiversity. We used virtual landscapes generated from data collected in a multi-decadal fire experiment to test how pyrodiversity—measured as spatial variation in fire frequency—shapes multiple dimensions of three ...

Assessing working lands as habitat for disturbance‐dependent birds using autonomous recording units

Restoration Ecology, EarlyView.
Abstract Introduction Working lands can provide habitat for declining disturbance‐dependent birds, such as Bachman's Sparrow (Peucaea aestivalis) and Northern Bobwhite (Colinus virginianus), but it remains unclear whether restoration following intensive land use (e.g. surface mining) yields habitat comparable to less intensive land uses (e.g.

Integrating natural baselines into ecosystem restoration: scaling herbivore targets for European landscapes

Restoration Ecology, EarlyView.
Abstract Introduction Herbivore‐mediated ecosystem processes are fundamental to biodiversity, yet have been greatly diminished by megafauna extinctions and replacement of wild herbivores by managed livestock. With increasing restoration ambitions—including the United Nations' (UN) Decade on Ecosystem Restoration and the European Union (EU) Nature ...

Fire frequency and timing influence bee–flower interactions: a case study from an oak‐pine savanna restoration on the Cumberland Plateau

Restoration Ecology, EarlyView.
Abstract Introduction Native plant communities have declined in the southeastern United States over the past century because of habitat loss and fire suppression. While restoration of these communities often requires prescribed fire, the effects of fire on endemic insects remain unclear.
