Estimating the total mortality of seabirds following a marine heat wave

Conservation Biology, EarlyView.
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

Prevalence of traded bird species in key biodiversity areas

Conservation Biology, EarlyView.
Abstract The use and trade of biodiversity involve tens of thousands of species that are exploited at a range of scales, intensities, and degrees of sustainability. As a result, some are highly threatened. Key biodiversity areas (KBAs) are sites of significance for the persistence of biodiversity identified nationally based on standardized criteria ...

Evaluating the protection status and exposure to warming of Caribbean reefs with high functional potential

Conservation Biology, EarlyView.
Abstract Over the past decades, climate change has emerged as a major threat to global biodiversity, negatively affecting the integrity and functioning of ecosystems and the benefits they provide to people. To mitigate these impacts, it is essential to identify climate refugia that support the persistence of the structure and function of reef ...

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal

Conservation Biology, EarlyView.
Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

Sobre o Uso da Persistência de Previsões Determinísticas de Vazão para a Tomada de Decisão

Revista Brasileira de Meteorologia, 2016
Resumo Previsões de vazão de médio prazo, que são geradas utilizando um modelo chuva-vazão forçado por previsões numéricas de precipitação, são muito úteis para a antecipação de eventos hidrológicos. Tradicionalmente estas previsões eram geradas de forma

Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

Wildlife Monographs, Volume 223, Issue 1, August 2026.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...
