DNA barcoding of Brazilian sea turtles (Testudines) [PDF]

Genetics and Molecular Biology, 2009
Five out of the seven recognized species of sea turtles (Testudines) occur on the Brazilian coast. The Barcode Initiative is an effort to undertake a molecular inventory of Earth biodiversity. Cytochrome Oxidase c subunit I (COI) molecular tags for sea turtle species have not yet been described.

Global conservation status of the jawed vertebrate Tree of Life [PDF]

Nature Communications
Human-driven extinction threatens entire lineages across the Tree of Life. Here we assess the conservation status of jawed vertebrate evolutionary history, using three policy-relevant approaches.

Adaptive evolution of major histocompatibility complex class I immune genes and disease associations in coastal juvenile sea turtles

Royal Society Open Science, 2022
Characterizing polymorphism at the major histocompatibility complex (MHC) genes is key to understanding the vertebrate immune response to disease. Despite being globally afflicted by the infectious tumour disease fibropapillomatosis (FP), immunogenetic ...

A new model of forelimb ecomorphology for predicting the ancient habitats of fossil turtles

Ecology and Evolution, 2021
Various morphological proxies have been used to infer habitat preferences among fossil turtles and their early ancestors, but most are tightly linked to phylogeny, thereby minimizing their predictive power. One particularly widely used model incorporates
