Molecular detection of hemogregarines and haemosporidians in Brazilian free-living testudines

International Journal for Parasitology: Parasites and Wildlife, 2018
Morphological and molecular techniques were used to investigate the presence of hemogregarines and haemosporidians in biological samples of free-living Geoffroy's side-necked turtles (Phrynops geoffroanus) and Giant Amazon turtles (Podocnemis expansa ...

Identifying the current and future status of freshwater connectivity corridors in the Amazon Basin

Conservation Science and Practice, Volume 5, Issue 1, January 2023., 2023
Freshwater connectivity corridors of the Amazon Basin are critical to maintain river services and biodiversity. Among rivers >500 km in length, there are currently 93 freshwater connectivity corridors (FCCs) that are either free‐flowing or of good connectivity status; one‐fifth of these FCCs would lose their free‐flowing status with buildout of ...

Cranial ecomorphology of turtles and neck retraction as a possible trigger of ecological diversification

Evolution, Volume 76, Issue 11, Page 2566-2586, November 2022., 2022
Abstract Turtles have a highly modified body plan, including a rigid shell that constrains postcranial anatomy. Skull morphology and neck mobility may therefore be key to ecological specialization in turtles. However, the ecological signal of turtle skull morphologies has not been rigorously evaluated, leaving uncertainties about the roles of ...

The comparative energetics of the turtles and crocodiles

Ecology and Evolution, Volume 12, Issue 6, June 2022., 2022
This paper discusses patterns in Dynamic Energy Budget parameters and implied traits that we found for turtles and crocodiles. We explain, for instance, why the proportionality of weight at birth with the square root of ultimate weight points to problems with water loss and nitrogen‐waste accumulation.
