The brown anole dewlap revisited: do predation pressure, sexual selection, and species recognition shape among-population signal diversity? [PDF]

open access: yesPeerJ, 2018
Animal signalling structures are amongst the most variable characteristics, as they are subjected to a diversity of selection pressures. A well-known example of a diverse signalling system in the animal kingdom is the dewlap of Anolis lizards.

Genomic Diversity of the Endangered Guinan Toad‐Headed Lizard and Its Conservation Implications

open access: yesIntegrative Zoology, EarlyView.
We produced HiFi long reads and assembled a high‐quality genome for the Guinan toad‐headed lizard—Phrynocephalus guinanensis—and present a comprehensive conservation genomics assessment. Our findings clearly show population structure, a reduced genetic diversity pattern, and a strong bottleneck in demographic history, reaffirming the endangered status ...

GEOGRAPHIC BODY SIZE AND SHAPE VARIATION IN A MAINLAND Anolis (SQUAMATA: DACTYLOIDAE) FROM NORTHWESTERN SOUTH AMERICA (COLOMBIA)

open access: yesActa Biológica Colombiana, 2014
Anolis auratus is a widely distributed species, from Costa Rica in Central America, through northern South America, including Colombia, Venezuela, northern Brazil, Surinam and the Guyanas.

Budding speciation, mitochondrial capture and introgression between surface and cave lineages in the Asellus aquaticus species complex

open access: yesCladistics, EarlyView.
Abstract Replicated pairs of ancestral and evolutionarily derived populations provide opportunities to test hypotheses about the deterministic laws of evolution. The Asellus aquaticus species complex is an invertebrate model system with several independent surface‐to‐cave transitions and a complicated and unresolved evolutionary history.

Hibernation of the Lizard, Anolis carolinensis

open access: yesExperimental Biology and Medicine, 1953
SummaryIn late summer and fall, body weight and to a greater extent liver weight increase due to the storage of glycogen and fat. With ithe increased storage of liver glycogen the blood glucose falls to a low level. In the winter and spring the blood sugar rises to a maximum and the liver glycogen and total lipids fall as the animal uses its body ...

LACK OF CONVERGENCE IN AQUATIC ANOLIS LIZARDS [PDF]

open access: yesEvolution, 2002
Why convergent evolution occurs among some species occupying similar habitats but not among others is a question that has received surprisingly little attention. Caribbean Anolis lizards, known for their extensive convergent evolution among islands in the Greater Antilles, are an appropriate group with which to address this question.

Heterodonty in the teeth of the turiasaurian sauropod from Angeac‐Charente (Early Cretaceous, southwestern France): Comparison of anatomical and geometric morphometric approaches

open access: yesJournal of Anatomy, EarlyView.
Turiasaurian teeth from Angeac‐Charente exhibit five dental morphotypes and reveal clear heterodonty and anteroposterior size gradient. Qualitative comparative anatomy quickly and efficiently identifies morphotypes, while 3D geometric morphometrics combined with machine learning refine ambiguous cases, demonstrating that qualitative and quantitative ...

Chromosome-scale genome assembly of the brown anole (Anolis sagrei), an emerging model species

open access: yesCommunications Biology, 2022
A highly-complete chromosome-scale genome assembly of the brown anole, Anolis sagrei, provides insight into the evolution of sex chromosomes and is a crucial resource for this model lizard species.

Integrative architecture and structural boundaries of the subdigital adhesive toe pads of Gekko gecko (Linnaeus, 1758) and guidelines for toe pad demarcation in other geckos

open access: yesJournal of Anatomy, EarlyView.
The adhesively competent toe pads of Gekko gecko (and other geckos) are delimited by a combination of external and deep anatomical features and cannot be identified based upon external scale form alone. We encourage future investigators to delimit toe pads in this functionally and anatomically meaningful fashion.

Impact of bauxite mining on mosquito communities (Diptera: Culicidae) and pathogen transmission risks in the eastern Amazon

open access: yesMedical and Veterinary Entomology, EarlyView.
Bauxite mining in the Amazon alters mosquito communities, favouring anthropophilic and generalist vectors while reducing species diversity and the variety of blood meal sources. Molecular analyses identified humans, tapirs and deer as the primary blood meal sources.
