The value of regeneration for insect fauna associated with leaf litter in the Brazilian savanna: A comparative study of biomass and trophic structure

Annals of Applied Biology, EarlyView.
This study demonstrates the ecological value of natural regeneration in the Brazilian Cerrado by analysing the biomass, richness and trophic structure of leaf litter insects across pasture (P), regenerating (R) and native (N) areas. We found that R areas supported insect communities more similar to N habitats than to Ps, with higher richness, greater ...

Devouring the Invaders: The Racial‐Ecological Politics of the Chinese Crayfish Trade in Kenya

American Anthropologist, EarlyView.
ABSTRACT This article examines entanglements of ecology, race, and foodways at Lake Naivasha in Kenya. Nonnative Louisiana red swamp crayfish (Procambarus clarkii), first introduced to Kenya in the 1960s, were once viewed as invasive but are now sought after as a delicacy among Kenya's Chinese community.

Extensive dissolution of live pteropods in the Southern Ocean [PDF]

, 2012
The carbonate chemistry of the surface ocean is rapidly changing with ocean acidification, a result of human activities. In the upper layers of the Southern Ocean, aragonite—a metastable form of calcium carbonate with rapid dissolution kinetics—may ...

Use of species’ responses to cryptic anthropogenic disturbances for monitoring biodiversity outcomes in tropical forests

Conservation Biology, EarlyView.
Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

Threatened or thriving? – The status of Serbian hoverflies on the IUCN European Red List of Hoverflies

Conservation Science and Practice, EarlyView.
Spatial distribution of Critically Endangered (CR) (a), Endangered (EN) (b), and Vulnerable (VU) (c) species in Serbia, showing overlap with Prime Hoverfly Areas (PHAs) and Protected Areas (PAs). Abstract Given the widespread decline of pollinators worldwide, assessing them using the IUCN criteria is crucial to understand their conservation status ...
