A comprehensive embryonic staging series of the turtle Trachemys scripta
Abstract Background Turtles hold a unique place in vertebrate evolutionary history, making them critical assets in embryology research. Yet, they remain understudied as potential model organisms in the field. Here, to support experimental manipulations with turtle embryos, we have created a complete normal table of development for comprehensive ...

Ontogeny of RSPO1, FOXL2, and RUNX1 during ovarian differentiation in the marsupial tammar wallaby
Abstract Background RSPO1 and FOXL2 are female sex‐determining genes involved in the differentiation and organization of the ovary in some eutherian mammals. Mutations or loss of function of these genes are associated with partial to full sex reversal in mice, humans, and goats.

Pulmonary development in Squamata: Insights from embryonic studies using micro‐CT
Abstract Background Pulmonary development in tetrapods is a complex process, especially within squamates, where single‐chambered, transitional, and multi‐chambered lungs can be found in adult animals. While the embryological development of the respiratory system of lizards and snakes was studied in a number of species between the 1830s and 1940s, the ...

Biophysical processes of morphogenesis in lizard lungs
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

Licensed To Kill: A Defense of Vicarious Liability Under the Endangered Species Act [PDF]
The Endangered Species Act (ESA) makes it illegal to take an endangered and threatened species by killing, harming, or harassing the animal. Although the classic example of a take is an individual poacher shooting an endangered species, these protected

Oogenesis and germinal bed morphology of the brown anole (A. sagrei)
Abstract Background The brown anole is a model species of the genus Anolis, a squamate (encompassing lizards and snakes) group widely studied in evolutionary, behavioral, and developmental biology. Full genome annotation, the establishment of gene editing techniques, and comprehensive description of reproductive tract morphology and embryogenesis in ...

Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

The rapid adoption of environmental DNA (eDNA) methods has drastically changed biodiversity monitoring efforts. It is often claimed that eDNA methods are more sensitive and efficient than conventional biodiversity monitoring methods, but it is often unclear what metrics support this claim.
