Ecology and Evolution, Volume 16, Issue 3, March 2026.We evaluated whether climatic gradients or spatial structure better explain body size variation in the South American rattlesnake (Crotalus durissus) across its wide geographic range. After explicitly accounting for spatial autocorrelation, climatic variables were not significant predictors of body size in either sex, whereas sex‐specific spatial ...

Ecosphere, Volume 17, Issue 3, March 2026.Abstract Long‐term studies of plant and animal populations are rare, particularly for long‐lived species with slow life histories. However, such studies are necessary to understand how population dynamics are affected by variation in vital rates. We used a large capture–recapture dataset spanning four decades (1983–2019) to estimate several population ...

Island‐restricted reptiles are more threatened but less studied than their mainland counterparts
Conservation Science and Practice, Volume 8, Issue 3, March 2026.Reptiles are highly diverse on islands, yet there is no comprehensive overview of island‐restricted reptiles (IRRs) regarding their distribution, threat status, and research efforts. Our assessment revealed that despite IRRs comprising nearly a quarter of global reptile species and 30.8% being threatened, only 7.2% of the literature focuses on them ...
