Journal of Biogeography, Volume 52, Issue 11, November 2025.ABSTRACT Aim The evolution of adaptive innovations carries strong eco‐evolutionary implications, allowing organisms to explore novel ecological opportunities, which facilitates lineage diversification. The remarkable diversity of reproductive strategies in amphibians provides a natural laboratory for identifying ecological mechanisms driving ...

Repeated Evolution of Digital Adhesion in Geckos: A Reply to Harrington and Reeder [PDF]
, 2017 We published a phylogenetic comparative analysis that found geckos had gained and lost adhesive toepads multiple times over their long evolutionary history (Gamble et al., PLoS One, 7, 2012, e39429).

Ecology and Evolution, Volume 15, Issue 10, October 2025.This first genomic insight into a key Mediterranean angelshark stronghold reveals an effective population size below critical conservation thresholds, high site fidelity, and multiple paternity. Despite evidence of active reproduction, ongoing bycatch remains a major threat, underscoring the urgent need for conservation actions. ABSTRACT Once common in

A Fetal-Maternal Shift of Blood Oxygen Affinity in an Australian Viviparous Lizard, Sphenomorphus quoyii (Reptilia, Scincidae) [PDF]
, 1981 Compared to adults, the oxygen affinity of blood from fetal Sphenomorphus quoyii is very much higher: P50 is approximately 70 Torr in adults and 30 Torr in nearly full term embryos (PC02= 17 Torr, T=34 degrees C).

First captive breeding of a night skink (Scincidae: Eremiascincus) from Timor-Leste, Lesser Sunda Islands, with remarks on the reproductive biology of the genus [PDF]
, 2016 We report two instances of captive breeding in a species of Timorese night skink (genus Eremiascincus Greer, 1979) in October and December 2012. Four and three neonates, respectively, with total lengths of ca 40 mm each, were discovered during routine ...

Pathological Parthenogenesis in Viviparous Toothcarps [PDF]
Nature, 1958 IN viviparous toothcarps parthenogenesis has been described in Lebistes reticulatus 1,2 and Xiphophorus helleri 2, while in this species also some cases of development of ovarial teratomas, caused by pathological parthenogenesis, are known3. In addition to these cases we observed a new one, namely in Heterandria formosa.

Notes on the Reproductive Biology of the Alabama Red Hills Salamander (Phaeognathus hubrichti ) [PDF]
, 2003 Living Amphibia exhibit two major life history modes, possession of an aquatic larval stage or direct development, with the latter assumed to be the derived evolutionary condition (Duellman and Trueb 1986, Wake 1989).

Effect of Spiroplasma infection on the mating behavior of Glossina fuscipes fuscipes
Insect Science, Volume 32, Issue 5, Page 1726-1736, October 2025.Abstract Tsetse flies are insects of significant public health and zoonotic importance as they are the main vectors of African trypanosomes. To date, an effective vaccine is unavailable and efforts to limit the spread of the disease primarily rely on controlling the tsetse populations.
