Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery

Conservation Biology, EarlyView.
Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

A global assessment of animal community responses to agricultural management

Conservation Biology, EarlyView.
Abstract Transitions in agricultural management through crop and noncrop diversification on intensively managed croplands or pastures have benefited biodiversity. However, the extent to which agricultural management benefits species communities present in undisturbed ecosystems remains largely unclear.

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 ...

Cualidades del paisaje construido de la vivienda y su impacto en la morfología y densidades de Bogotá

Revista INVI, 2019
Diferentes estudios internacionales han catalogado a Bogotá, Colombia, como una de las ciudades con mayor densidad del mundo, sin embargo, al interior esta densidad está matizada por las características diferenciales del paisaje construido de la vivienda.

Identifying hotspots of faunal data deficiency to direct urgent research and monitoring

Conservation Biology, EarlyView.
Abstract Data deficiency is a substantial challenge for extinction risk assessments because incomplete data means we cannot accurately identify priority protected areas for conservation. Here, we use the International Union for Conservation of Nature (IUCN) distributions of amphibians, sharks and rays, fish, mammals, birds, and reptiles to identify ...

Subsistence hunting shapes the spatial variation of jaguar densities in community‐managed forests

Journal of Zoology, EarlyView.
Jaguars and people can coexist in community‐managed forests, but distance matters. In Guatemala's Maya Biosphere Reserve, jaguar numbers increased markedly in areas harder to reach on foot, yet jaguars were still found near communities, showing that responsibly managed forests can support jaguar populations while allowing people to maintain traditional
