Exploring the exploration: implications of leaving or remaining at the natal site during the early stages of independence in a partially migratory bird

Ibis, EarlyView.
Despite being an important fraction of any animal population, juveniles are a severely understudied group. Juveniles often need to learn an array of skills that allow them to survive independently and do so while undertaking decisions that may impact their fitness, recruitment and survival, having therefore relevant demographic implications.

Sobrevivencia de las PYME en Chile

Estudios Públicos, 2007
Este estudio analiza la relacion entre probabilidad de sobrevivencia y tamano de plantas en las pequenas y medianas empresas (PYME). Utilizando una base de datos para la industria manufacturera que cubre el periodo 1979-1999, se analiza si las PYME han experimentado efectos negativos en su probabilidad de sobrevivencia en el tiempo.

The Renal Function of the Wild Rodent Cerradomys goytaca Reveals Adaptations in the Mechanisms of Urinary Concentration and Solute Excretion

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 7, Page 772-784, August 2026.
Renal adaptations of Cerradomys goytaca associated with survival in its natural habitat. Graphical Abstract of the main renal physiological characteristics identified in C. goytaca. This species exhibits an increased kidney mass index, elevated urine osmolality, and enhanced tubular water reabsorption, indicating a higher capacity for water ...

Demographic buffering in natural populations: A multi‐level perspective

Journal of Animal Ecology, Volume 95, Issue 8, Page 1298-1310, August 2026.
We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

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.
