Trade and socioeconomic importance of an invasive giant snail in the endemic‐rich island of São Tomé, Central Africa

Conservation Biology, Volume 38, Issue 5, October 2024.
Abstract Managing invasive species is crucial to mitigate their negative impacts on ecosystems, yet conflicts may arise when their social benefits are disregarded. Human pressure on the endemic‐rich forests of São Tomé has been high since the island was discovered by the Portuguese in the 15th century, and numerous species have been introduced.

Global mismatches between threat mapping research effort and the potential of threat abatement actions to reduce extinction risk

Conservation Biology, Volume 38, Issue 4, August 2024.
Abstract Threat mapping is a necessary tool for identifying and abating direct threats to species in the ongoing extinction crisis. There are known gaps in the threat mapping literature for particular threats and geographic locations, and it remains unclear if the distribution of research effort is appropriately targeted relative to conservation need ...

Associations between a feral equid and the Sonoran Desert ecosystem Asociaciones Entre un Equino Salvaje y el Ecosistema del Desierto Sonorense

Wildlife Monographs, Volume 215, Issue 1, July 2024.
We documented negative associations between feral burros and several elements of the Sonoran Desert ecosystem, and suggest that differences associated with this feral equid may be ecologically important and may have the potential to affect the long‐term viability of this ecosystem.

Effects of wind turbine noise on songbird behavior during nonbreeding season

Conservation Biology, Volume 38, Issue 2, April 2024.
Abstract Anthropogenic noise is one of the fastest growing, globally widespread pollutants, affecting countless species worldwide. Despite accumulating evidence of the negative impacts of wind turbines on wildlife, little is known about how the noise they generate affects ecological systems.

La Distribución Binomial Negativa en el Estudio de Poblaciones de Insectos

Revista Facultad Nacional de Agronomía Medellín, 1984
A diferencia de los fenómenos físico-químicos que pueden estudiarse bajo modelos matemáticos muy precisos, los fenómenos biológicos están sujetos a un grado apreciable de incertidumbre debido a la complejidad de los factores que los gobiernan.
