Dogs are among the most variable species today, but little is known about the morphological variability in the early phases of their history. The Neolithic transition to farming may have resulted in an early morphological diversification as a result of changes in the anthropic environment or intentional selection on specific morphologies. Here, we explore the variability and modularity in mandible form by comparing 525 dog mandibles from European archaeological sites ranging from 8,100 to 3,000...

The impact of paleoclimatic changes on body size evolution in marine fishes

Emily Troyer, Ricardo Betancur-R, Lily Hughes, Mark Westneat, Giorgio Carnevale, William White, John Pogonoski, James Tyler, Carole Baldwin, Guillermo Ortí, Julien Clavel, Dahiana Arcila & Andrew Brinkworth
Body size is an important species trait, correlating with lifespan, fecundity, and other ecological factors. Over Earth’s geological history, climate shifts have occurred, potentially shaping body size evolution in many clades. General rules attempting to summarize body size evolution include Bergmann’s rule, which states that species grow to larger sizes in cooler environments and smaller sizes in warmer environments; and Cope’s rule, which poses that lineages tend to increase in size over evolutionary time. Tetraodontiform...

Deep-time reticulation and ancient mitochondrial genome capture during the radiation of Jamaican Anolis lizards (Squamata; Iguanidae)

Edward Myers
Gene flow and reticulation are increasingly recognized as important processes in the diversification of many taxonomic groups. With the increasing ease of collecting genomic data and the development of multispecies coalescent network approaches, such reticulations can be accounted for when inferring phylogeny and diversification. Caribbean Anolis lizards are a classic example of an adaptive radiation in which species have independently radiated on the islands of the Greater Antilles into the same ecomorph classes. Within the...

Dataset of punctual observations along soil moisture gradients in France

Guillaume Gayet, François Botcazou, Jean-Manuel Gibeault-Rousseau, Laurence Hubert-Moy, Sebastien Rapinel & Blandine Lemercier
The interface between wetlands and uplands is characterized by gradients in hydrological, soil and biological components. Consequently, the exact spatial distribution of this transitional area is not well known because it often occurs as a fuzzy moisture gradient. However, ecological assessment and conservation require mapping and characterizing this interface to better understand and model biotic and abiotic interactions between wetlands and uplands. To this end, in 2021 and 2022, we observed soil properties and vegetation...

Deux espèces nouvelles pour la faune des serpents du Laos

Anne Lottier & Patrick David
Résumé – Nous mentionnons pour la première fois au Laos la présence de deux espèces de serpents de la famille des Natricidae: Hebius bitaeniatus (Wall, 1925) et Rhabdophis leonardi (Wall, 1923). Elles ont été observées dans le sud de la province du Xiangkhoang en septembre 2019 lors d’un voyage naturaliste. Nous confirmons aussi la présence de Ptyas nigromarginata (Blyth, 1854) pour laquelle nous présentons la seconde localité connue au Laos. Mots-clés : Hebius, Rhabdophis, Ptyas,...

Data from \"Evidence of attack deflection suggests adaptive evolution of wing tails in butterflies\"

Ariane Chotard
Predation is a powerful selective force shaping many behavioural and morphological traits in prey species. The deflection of predator attacks from vital parts of the prey usually involves the coordinated evolution of prey body shape and colour. Here, we test the deflection effect of hindwing tails in the swallowtail butterfly Iphiclides podalirius. In this species, hindwings display long tails associated with a conspicuous colour pattern. By surveying the wings within a wild population of I....

Supplementary datasets for: Prodigious polyphyly in Pleuroceridae (Gastropoda: Cerithioidea)

Nathan Whelan, Paul Johnson, Jeffrey Garner, Nicole Garrison & Ellen Strong
Phylogenomic studies with hundreds or thousands of loci are rare for most invertebrate groups, including freshwater gastropods. This can prevent understanding of phylogeny, which hinders many areas of research. Pleuroceridae is a family of freshwater snails that is highly imperiled and plays an essential role in the ecology of many freshwater systems of the eastern United States. However, the evolutionary history of the family is not understood, and the systematics of the family has not...
