Precipitation and Temperature‐Dependent Locomotor Performance Drive the Abundance of a Neotropical Lizard

open access: yesBiotropica, Volume 57, Issue 6, November 2025.
We investigated how climate and ecophysiology affect the demography of the lizard Tropidurus oreadicus in the Brazilian Cerrado. While lizards were more frequently captured in the dry season, their abundance peaked during the rainy season when their locomotor performance was highest.

Marked tree demographic variation along subtle elevation differences partially explains species' habitat associations in an Amazonian forest

open access: yesJournal of Ecology, Volume 113, Issue 10, Page 2860-2874, October 2025.
These findings show that even small differences in elevation can lead to biologically meaningful variation in resource access that translates into significant differences in tree growth and survival. However, resource access could not fully explain the patterns of topographically driven demographic variation we observed. While certain species may still

Assessing limits of sustainable seed harvest in wild plant populations

open access: yesConservation Biology, Volume 39, Issue 5, October 2025.
Abstract Seed harvesting from wild plant populations is key for ecological restoration, but it may threaten the persistence of the source populations. Consequently, several countries have set guidelines limiting the proportions of harvestable seeds. However, these guidelines are inconsistent and lack a solid empirical basis.

Demographic performance review of a reintroduction project: Iberian lynx in Extremadura

open access: yesJournal of Applied Ecology, Volume 62, Issue 9, Page 2189-2201, September 2025.
Demographic performance reviews are essential for understanding the drivers of population growth and for evaluating the outcomes of reintroduction initiatives. IPMs as exemplified by our Iberian lynx case study provide a powerful and flexible framework for quantifying reintroduction performance and addressing key research and management questions.

Influences on cannabis policy design and adaptation in the American states

open access: yesPolicy Studies Journal, Volume 53, Issue 3, Page 723-746, August 2025.
Abstract Despite federal prohibitions, three‐quarters of states had implemented medical marijuana laws (MML) and one‐third had implemented recreational cannabis laws (RCL) by 2020. State policy designs varied considerably, and we focus on policy development and maturation in policy implementation, examining factors influencing design features of policy

Forest citizens and people‐centered conservation in the Brazilian Amazon

open access: yesConservation Biology, Volume 39, Issue 3, June 2025.
Abstract Demands for territorial recognition are foundational to the claiming of rights by forest‐proximate people who attempt to conserve their forests. The rights of these often‐marginalized populations have been largely overlooked by conservationists, yet they are central to achieving people‐centered conservation. We further developed the concept of
