Long‐term jaguar demography underscores the ecological value of Amazonian floodplains

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Our results provide the first estimates of recruitment and apparent survival for Amazonian jaguars, key parameters for guiding conservation. We show that seasonal wetlands—the Amazonian floodplain forest and reported estimates from Pantanal and the Llanos—harbour the highest jaguar densities across the species' range.

La creciente dependencia de mano de obra migrante para tareas agrícolas en el centro global. Una perspectiva comparada

Estudios Geográficos, 2020
Numerosos estudios, sobre todo en las últimas décadas, han señalado el progresivo aumento del número de migrantes realizando trabajo agrícola en los Estados del centro global. Desde el paradigma de la ecología-mundo, se teorizó sobre el hecho de que este

Question the Mark: A Review and Assessment of Bat Marking Practices

Mammal Review, Volume 56, Issue 1, March 2026.
We reviewed a decade of research on bats and conducted a broader systematic review to assess the nature of bat marking practices and the effects and efficacy of marks. Effects of marks on bats, mark details and marking procedures are rarely reported and further research on the effects of marks on bats and more thorough reporting are needed.

Addressing Demographic Challenges Through Public–Private Partnerships: In Vitro Fertilization in Latvia

World Medical &Health Policy, Volume 17, Issue 4, Page 688-694, December 2025.
ABSTRACT The study by Morshed‐Behbahani et al. highlights that financial barriers are not the sole obstacle to accessing infertility treatment. To ensure equal access for all, infertility treatment should be regarded as a universal human right, with the public sector assuming responsibility for its provision.

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

Biotropica, 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

Journal 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

Conservation 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

Journal 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.
