People and Nature, EarlyView.Abstract The expansion of grey wolves (Canis lupus) across the western United States, including on public lands used for extensive livestock grazing, requires tools and techniques for reducing wolf–livestock conflict and supporting coexistence. We examined approaches used on forested lands managed by the U.S.

First Evidence for Adoption in California Sea Lions
PLoS ONE, 2010 Demographic parameters such as birth and death rates determine the persistence of populations. Understanding the mechanisms that influence these rates is essential to developing effective management strategies. Alloparental behavior, or the care of non-filial young, has been documented in many species and has been shown to influence offspring survival.

Agroforestry and enhanced rock weathering: A dual strategy for sustainable cacao
PLANTS, PEOPLE, PLANET, EarlyView.Cacao production is both economically vital and environmentally intensive, presenting a major sustainability challenge as a crop largely cultivated by smallholder farmers in climate‐vulnerable regions. This review synthesises evidence that integrating agroforestry with enhanced rock weathering (EW) may significantly reduce emissions from cacao ...
