Population Variation in Steroid Hormone‐Related Gene Expression and Sexually Dimorphic Communication in the Electric Fish Apteronotus albifrons

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The development and maintenance of sexually dimorphic behavior often depends on gonadal steroids. Interspecific variation in the magnitude of behavioral sex differences may be mediated by differences in steroid action on neural circuits controlling behavior.

VOCALIZATION OF THE CROCODILE SKINK, TRIBOLONOTUS GRACILIS (DE ROOY, 1909), AND EVIDENCE OF PARENTAL CARE. [PDF]

, 2001
The crocodile or spiny skinks, Tribolonotus, comprise eight secretive semi-fossorial lizards, which are generally found under vegetation in the immediate vicinity of water (Greer and Parker, 1968; O'Shea, 1991, 1994; Rogner, 1997). Tribolonotus gracilis (

The Interplay of Ontogeny and Phylogeny at the Transcriptome Level of the Tetrapod Heart

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
The main stages of development during which species‐specific heart anatomy is determined in the ontogeny of representative tetrapods. Transcriptomic similarity is expected earlier in development before heart anatomy diverges. ABSTRACT The tetrapod heart is characterized by three chambers in amphibians and non‐avian reptiles, as opposed to four in birds,

The impact of gigafire on vegetation structure, terrestrial vertebrate abundance and diel activity

Oikos, EarlyView.
Fire regimes are shifting around the world due to climate and land‐use change, resulting in an increased frequency of large and severe wildfires. However, the impact of extreme wildfire events on animal species remains poorly understood. Particularly lacking is an understanding of how fire affects animal behaviour.

The Western Amazonian Richness Gradient for Squamate Reptiles: Are There Really Fewer Snakes and Lizards in Southwestern Amazonian Lowlands?

Diversity, 2019
The lowland rainforests of the Amazon basin harbor some of the most species-rich reptile communities on Earth. However, there is considerable heterogeneity among climatically-similar sites across the Amazon basin, and faunal surveys for southwestern ...

Relatedness, trait evolution, and climatic niche divergence in mammalian island endemics

Oikos, EarlyView.
Island mammals have influenced ecological and evolutionary theory since Darwin, and many of them provide textbook examples of the dramatic morphological evolution that often occurs in island communities. However, patterns of evolution in the climatic niches of island mammals have yet to be fully explored.

Anatomy, morphology and evolution of the patella in squamate lizards and tuatara (Sphenodon punctatus) [PDF]

, 2016
The patella (kneecap) is the largest and best-known of the sesamoid bones, postulated to confer biomechanical advantages including increasing joint leverage and reinforcing the tendon against compression.
