What Drives Variation in Habitat Use by Anolis Lizards: Habitat Availability or Selectivity? [PDF]

open access: yes, 2006
Geographic variation in habitat availability may drive geographic variation in a species' habitat use; alternatively, species adapted to particular habitat characteristics may use a habitat regardless of its availability within an environment.

The Coevolution of Colour Patterns and Hindwing Shapes on a Large Phylogenetic Scale Reveals Predation‐Driven Adaptive Syndromes in Swallowtail Butterflies

open access: yesEcology Letters, Volume 29, Issue 1, January 2026.
By combining computer vision and morphometrics on museum specimens, we show that hindwing tail shape and colour patterns evolved in concert across swallowtails. Long‐tailed species display contrasted stripes and marginal spots, suggesting coevolution of deflective traits promoted by natural selection by predators.

Island time and the interplay between ecology and evolution in species diversification. [PDF]

open access: yes, 2015
Research on the dynamics of biodiversity has progressed tremendously over recent years, although in two separate directions - ecological, to determine change over space at a given time, and evolutionary, to understand change over time.

Condition‐Dependent Responses to Risk in a Small Mammal

open access: yesEthology, Volume 132, Issue 1, Page 55-66, January 2026.
Responses to a predation risk gradient vary as a function of the resource environment and individual condition in a small mammal. ABSTRACT Animal responses to risky situations are shaped by both environmental (external) cues and internal states such as body condition.

Fine‐Scale Bioregionalization in a Complex Island System: A Freshwater Perspective From the Greater Antilles

open access: yesJournal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim The isolated nature of islands makes them particularly vulnerable to climate change. The freshwater fishes of the Greater Antilles remain understudied and are further threatened by habitat fragmentation and the introduction of exotic invasive species.

Somatic mutations render human exome and pathogen DNA more similar

open access: yes, 2019
Immunotherapy has recently shown important clinical successes in a substantial number of oncology indications. Additionally, the tumor somatic mutation load has been shown to associate with response to these therapeutic agents, and specific mutational ...

Morphological traits and environmental preferences of the Blunt‐headed tree snake Imantodes cenchoa: the effects of sex and ontogeny

open access: yesJournal of Zoology, Volume 328, Issue 1, Page 41-51, January 2026.
Understanding how animals interact with their environment across life stages is key for conservation. In our long‐term study of the Blunt‐headed tree snake (Imantodes cenchoa) in the tropical rainforest of Los Tuxtlas, Mexico, we tracked over 240 individuals and found age‐related differences in environmental preferences.

Evolutionary lability in Hox cluster structure and gene expression in Anolis lizards

open access: yesEvolution Letters, 2019
Hox genes orchestrate development by patterning the embryonic axis. Vertebrate Hox genes are arranged in four compact clusters, and the spacing between genes is assumed to be crucial for their function. The genomes of squamate reptiles are unusually rich
