Developmental stage ordering yields greater cranial mineralization sequence resolution than embryo size or days since oviposition: A case study using the gekkotan Eublepharis macularius (Blyth, 1854)

Journal of Anatomy, Volume 249, Issue 4, Page 847-864, October 2026.
We employ a set of leopard gecko embryos for which size, day of development, and developmental stage are known to assess which timetable accords with the greatest resolution of cranial mineralization events. Developmental staging yielded the best outcome. Abstract Mineralization sequences of cranial elements (often referred to as ossification sequences)

Estimating Area of Occupancy From Incomplete Occurrence Records: Reproducible Workflow Illustrated on a Comprehensive Dataset of Georgian Snakes

Ecology and Evolution, Volume 16, Issue 9, September 2026.
The workflow is presented that helps to optimize grid‐cell size by breakpoint search and to estimate the area of occupancy (AOO) more precisely, if the occurrence data are incomplete. The model was validated on 13 colubrid snakes found in Georgia. The scripts in R and full statistical workflow are provided in the paper and the Supporting Information ...

Amphibians and reptiles from Floresta Nacional de Pau-Rosa, Amazonas, Brazil: an important protected area at the heart of Amazonia [PDF]

Acta Amazonica, 2017
Amazonia harbors the largest and most diverse tropical forest in the world, but knowledge about the species diversity of the region is still far from ideal.

Tree cavities as keystone structures in a semiarid region: Interspecific aggregations of anurans in the Brazilian Caatinga

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Tree cavities function as key microclimatic refuges for anurans in the semiarid Caatinga biome of northeastern Brazil, where we document previously unreported interspecific aggregations during the dry season. Observations from fauna rescue operations preceding vegetation clearance revealed eight distinct aggregations within cavities of two ...

Long‐Term Population Declines of Habitat‐Shifting Species in the City: A Living Planet Index Approach for Berlin, Germany

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
We applied two global biodiversity indices at a city scale and revealed significant declines in odonate and amphibian populations in freshwater systems over several decades. Our study demonstrates the effectiveness of both indices as a baseline for fulfil urban‐related biodiversity framework targets if suitable biodiversity time series are available ...

Spatiotemporal Thermal Variation Modulates Phenotypic Plasticity in Freshwater Turtle Growth, Behavior, and Sex

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Using a dataset that spans more than 50 years, we found that northern map turtles (Graptemys geographica) – an ectothermic species with temperature‐dependent sex determination – exhibited faster somatic growth rates, altered thermoregulatory behaviors, and a female‐biased sex ratio in recent years which were characterized by warmer, longer growing ...

Identifying Potential Connectivity for an Urban Population of Rattlesnakes (Sistrurus catenatus) in a Canadian Park System

Land, 2020
In the face of ongoing habitat loss and fragmentation, maintaining an adequate level of landscape connectivity is needed to both encourage dispersal between habitat patches and to reduce the extinction risk of fragmented wildlife populations.
