Comparative review of entanglement risk assessments for cetacean conservation and management

Conservation Biology, EarlyView.
Abstract Cetacean entanglement in fishing gear remains a major global threat that exposes persistent gaps in how fisheries management frameworks manage risk to nontarget species. Ecological risk assessment (ERA) offers a structured way to link exposure and consequences to an explicit statement of risk, but entanglement risk assessments vary widely in ...

Improving efficiency in conservation planning by modeling species‐specific responses to threat abatement

Conservation Biology, EarlyView.
Abstract Reversing ongoing biodiversity loss requires effectively managing anthropogenic threats. Although conservation actions can mitigate these threats, prioritizing and targeting such actions remain challenging because species respond differently depending on the nature of the threats and their biological traits.

Evaluating a structured expert elicitation approach for adaptive conservation management based on lessons from five years in practice

Conservation Biology, EarlyView.
Abstract Adaptive management of threatened species relies on having ex ante estimates of species’ responses to different interventions. Structured expert elicitation is often used to generate these estimates, but comparisons of these expert‐predicted outcomes with observed results are rare.

Genomics‐informed management of ex situ populations

Conservation Biology, EarlyView.
Abstract The European Association of Zoos and Aquariums (EAZA) manages insurance populations for hundreds of species through its EAZA ex situ programs (EEPs). EEPs help safeguard against extinction in the wild and provide source populations for genetic rescue programs.

Protected areas on international borders show uneven conservation outcomes

Conservation Biology, EarlyView.
Abstract Border protected areas (BPAs) are national protected areas that are immediately adjacent to a country's border or span two or more countries; they are characterized by distinctive opportunities and pressures. They play a critical role in protecting carbon‐rich ecosystems, conserving endangered biodiversity, reducing cross‐border environmental ...

Armas biológicas ¿una amenaza terrorista para Colombia?

Revista de Relaciones Internacionales, Estrategia y Seguridad, 2008
Las armas biológicas, naturales y o sintéticas, son productos generados a partir de algún organismo vivo o derivado de su manipulación físico-química. Hasta hace poco tiempo para los colombianos, los ataques mercenarios con microorganismos no generaban

Codesigning synergies among ecological, social, and economic benefits with landscape‐scale agri‐environmental schemes

Conservation Biology, EarlyView.
Abstract Global farmland biodiversity is declining rapidly, threatening both natural ecosystems and agricultural production. Although agri‐environmental schemes incentivize farmers to adopt environmentally friendly measures, the spatial mismatch between their local implementation and the landscape‐scale habitat requirements of farmland species has been
