Hacia una síntesis biogeográfica de México Toward a synthesis of Mexican biogeography

open access: yesRevista Mexicana de Biodiversidad, 2005
El reconocimiento de componentes bióticos constituye una primera etapa hacia una teoría biogeográfica sintética. En México podemos caracterizar 3 componentes bióticos principales, cada uno con una combinación diferente de elementos bióticos.

Military lands provide an opportunity to recover red wolves

open access: yesThe Journal of Wildlife Management, EarlyView.
Red wolf (Canis rufus) recovery remains challenging, with only one population persisting and no reintroductions since 1998. Despite extensive, biodiverse properties in the Southeast with conservation mandates, military lands have been overlooked. In our paper, we evaluate them as a potential path forward for red wolf reintroduction sites.

Nexus of Urbanization, Land Degradation, and Agricultural Sustainability: A Global Bibliometric Review

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Rapid urban expansion has become a global concern that increasingly encroaches on agricultural land and threatens food security, environmental sustainability, and rural livelihoods. This study offers a comprehensive bibliometric review of global research at the crossroads of urbanization, agricultural land degradation, and food security.

Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...
