Potential Invasive Indo‐Pacific Acropora in a Coral Reef of Venezuela: A Contribution to Their Morphological and Molecular Knowledge

Ecology and Evolution, Volume 16, Issue 3, March 2026.
We report the first record of a non‐native hermatypic coral in Venezuela, exhibiting biological traits characteristic of invasive species. The coral is a member of the genus Acropora (Scleractinia: Acroporidae), native to the Indo‐Pacific. This non‐native petrous coral occurred in a reef of the Morrocoy National Park, in the southern Caribbean.

Phenotypic and Ecological Correlates of Population Decline in the World's Anurans

Ecology and Evolution, Volume 16, Issue 3, March 2026.
In this study, we assess the ecological and environmental factors associated with population decline in the world's anurans, taking into account their evolutionary relationships. A large majority of evaluated species were in decline. Range size and temperature annual range were negatively correlated with decline, whereas latitude was positively ...

Clinal Variation in Reproductive Modes and Offspring Body Condition Across a Contact Zone of a Bimodal Viviparous Salamander

Ecology and Evolution, Volume 16, Issue 3, March 2026.
We examined clinal gradients in reproductive modes and associated offspring body condition across a hybrid zone between two bimodal viviparous subspecies of Salamandra salamandra. We found a clear cline in reproductive modes, with pure modes at the extremes and mixed modes in central populations.

Spatial Structure Explains Morphological Variation Better Than Climatic Gradients in the South American Rattlesnake (Crotalus durissus)

Ecology and Evolution, Volume 16, Issue 3, March 2026.
We evaluated whether climatic gradients or spatial structure better explain body size variation in the South American rattlesnake (Crotalus durissus) across its wide geographic range. After explicitly accounting for spatial autocorrelation, climatic variables were not significant predictors of body size in either sex, whereas sex‐specific spatial ...

Physiology–microhabitat matching may help organisms cope with the thermal and hydric challenges under climate change: a tale of two lizards

Ecography, Volume 2026, Issue 3, March 2026.
Climate change is significantly affecting biodiversity, and organisms that depend on external temperature – such as ectotherms – are particularly vulnerable to these effects. Microhabitats provide refuge for species, thereby reducing exposure to thermal and hydric stress under climate change.

Osteology of the Feeding Apparatus of Chilean Flamingo Phoenicopterus chilensis (Aves: Phoenicopteridae)

Journal of Morphology, Volume 287, Issue 3, March 2026.
1. The skull features a broad, dorsoventrally flattened frontal region articulating with an elongated upper jaw that is complemented by the mandible's downward bend along its proximal half. 2. The low mechanical advantage in the mandible is attributed to the reduced and shallow insertion areas of the adductor muscles, which are positioned close to the ...

A response to ‘Quantifying phenotypic plasticity at multiple levels—A comment on Gómez et al.’

Functional Ecology, Volume 40, Issue 3, Page 560-562, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In this reply, we clarify several conceptual misunderstandings raised in response to our Perspective on quantifying phenotypic plasticity. We emphasize that our central argument concerns the rigorous estimation of the magnitude of plasticity, rather than its mere ...
