Veterinary Parasitology, 2010 Little is known on how hematozoan infection changes reptile hematology. The lizard Ameiva ameiva is widely distributed in the Americas and is infected by hematozoan parasites. Previous studies on this lizard have shown that the parasite of monocytes causes a variety of ultrastructural changes in infected host cells.

Ecology and Evolution, Volume 9, Issue 22, Page 12471-12481, November 2019., 2019 The ecological processes that underpin the gut microbiome's metabolic response might involve rapid turnover of the gut microbiome in response to new metabolic challenges, or it might entail maintaining sufficient diversity in the microbiome that any new metabolic demands can be met from an existing set of bacteria.

Patterns of frugivory in the columnar cactus Pilosocereus leucocephalus
Ecology and Evolution, Volume 9, Issue 3, Page 1268-1277, February 2019., 2019 Birds and bats feed on the fruit, and presumably disperse, the seeds of Pilosocereus leucocephalus, a keystone columnar cactus species in Mesoamerica Abstract In the frugivory networks of many arid and semi‐arid Mesoamerican ecosystems, columnar cacti act as keystone species that produce fruits with a high content of water and nutrients attractive to ...

Ecology and Evolution, Volume 8, Issue 4, Page 2108-2121, February 2018., 2018 According to the patterns of body temperature in relation to environmental temperature, Aldabra giant tortoises act as conformer–regulators. In the wild, tortoises modify their daily and seasonal activity and regulate their body temperature close to 30°C.

Performance of Cerrado lizards: a test of the center–periphery hypothesis
Ecography, Volume 2025, Issue 11, November 2025.The center–periphery hypothesis (CPH) states that species' demographic performance declines from the center towards the periphery of their geographic range due to increasingly suboptimal environmental conditions. We tested the predictions under the CPH using two lizard lineages with different activity patterns and distributions, taking lizard body ...
