The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Conservación de los recursos fitogenéticos: uso inteligente de la biodiversidad

Revista Biológico Agropecuaria Tuxpan, 2018
Los recursos fitogenéticos están representados por toda la variedad y combinaciones posibles de rasgos que permiten a las especies vegetales adaptarse a los cambios en el medio; a mayor cantidad de rasgos y combinaciones, mayor es la probabilidad de que

La capacidad poblacional de españa [PDF]

Reis, 1979
Se examina el concepto de población óptima y lo que ello constituye en términos de agricultura, defensa, espacio, etc., con especial referencia a los datos españoles. Se sostiene que la sobrepoblación no puede darse en términos absolutos, sino que su posibilidad real depende de la producción agraria, las oportunidades de empleo, la productividad y el ...

An experimental approach to assess the combined effects of multiple stressors on a large vertebrate species

Conservation Biology, EarlyView.
Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

Report on the Poblacion Flotante of Bogota (D.C.)

CoRR, 2016
In this document we describe the size of the Poblacion Flotante of Bogota (D.C.). The Poblacion Flotante is composed by people who live outside Bogota (D.C.), but who rely on the city for performing their job. We estimate the Poblacion Flotante impact relying on a new data source provided by telecommunications operators in Colombia, which enables us to

Constructed value of information with iterative scoring and parametric uncertainty to identify management‐relevant research priorities for a declining raptor species

Conservation Biology, EarlyView.
Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities

Conservation Biology, EarlyView.
Abstract Effectively managing human–wildlife interactions is crucial for fostering coexistence on shared landscapes. Management options are most effective when aligned with the preferences of people directly affected by wildlife, yet little is known about how socioecological factors influence these preferences.
