Environmental data from: Potential distributions of invasive vertebrates in the Iberian Peninsula under projected changes in climate extreme events

Rocío A. Baquero, A. Márcia Barbosa, Daniel Ayllón, Carlos Guerra, Enrique Sánchez, Miguel B. Araújo & Graciela G. Nicola
This dataset includes climatic variables representing extreme events indices defined by the World Meteorological Organization (https://public.wmo.int/en). The variables were calculated based on five Regional Climate Models or RCMs (UAHE-REM, UCAN-WRA, UCAN-WRB, UCLM-PRO and UMUR-MM5) for the periods 1971-2000 (‘current climate’) and 2021-2050 (‘future climate’) under the SRES A1B Emissions Scenario. We used RCMs instead of global climate models (GCMs) because the latter have an overly coarse resolution compared to the spatial resolution of our species...

Deconstructing incubation behaviour in response to ambient temperature over different timescales

David Diez-Méndez, Caren Cooper, Juan José Sanz, Jose Verdejo & Emilio Barba
Avian embryos need a stable thermal environment to develop optimally, while incubating females need to allocate time to self-maintenance off the nest. In species with female-only incubation, eggs are exposed to ambient temperatures that usually cool them down during female absences. The lower the ambient temperature the sooner females should return to re-warm the eggs. When incubation constraints ease at increasing ambient temperatures, females respond by increasing either incubation effort or self-maintenance time. These responses...

Quantitative genetics of extreme insular dwarfing: the case of red deer (Cervus elaphus) on Jersey

José Alexandre Felizola Diniz-Filho, Ana Santos, Elisa Barreto, Felipe Naves, Wanderson Santos, Kelly Souza, Rejane Santos-Silva, Ricardo Dobrovolski, Thannya Soares, Rosana Tidon, Zander Spigoloni, Thiago Rangel, Pasquale Raia, Joaquín Hortal & Lucas Jardim
Aim: The Island Rule – i.e. the tendency for body size to decrease in large mammals and increase in small mammals on islands has been commonly evaluated through macroecological or macroevolutionary, pattern-orientated approaches, which generally fail to model the microevolutionary processes driving either dwarfing or gigantism. Here, we seek to identify which microevolutionary process could have driven extreme insular dwarfism in the extinct dwarf red deer population on the island of Jersey. Location: Jersey, UK...

Rapid radiation and rampant reticulation: Phylogenomics of South American Liolaemus lizards

Damien Esquerre, Scott Keogh, Diego Demangel, Mariana Morando, Luciano Avila, Francisco Ferri-Yáñez & Adam Leaché
Understanding the factors that cause heterogeneity among gene trees can increase the accuracy of species trees. Discordant signals across the genome are commonly produced by incomplete lineage sorting (ILS) and introgression, which in turn can result in reticulate evolution. Species tree inference using the multispecies coalescent is designed to deal with ILS and is robust to low levels of introgression, but extensive introgression violates the fundamental assumption that relationships are strictly bifurcating. In this study,...

Pervasive admixture and the spread of a large-lipped form in a cichlid fish radiation

Will Sowersby, José Cerca, Bob Wong, Topi Lehtonen, David Chapple, Mariana Leal-Cardin, Marta Barluenga & Mark Ravinet
Adaptive radiations have proven important for understanding the mechanisms and processes underlying biological diversity. The convergence of form and function, as well as admixture and adaptive introgression, are common in adaptive radiations. However, distinguishing between these two scenarios remains a challenge for evolutionary research. The Midas cichlid species complex (Amphilophus spp.) is a prime example of adaptive radiation, with phenotypic diversification occurring at various stages of genetic differentiation. One species, A. labiatus, has large fleshy...

Dispersal syndromes are poorly associated with climatic niche differences in the Azorean seed plants

María Leo, Manuel J. Steinbauer, Paulo A. V. Borges, Eduardo B. De Azevedo, Rosalina Gabriel, Hanno Schaefer & Ana M. C. Santos
Aim: Environmental niche tracking is linked to the species ability to disperse. While well investigated on large spatial scales, dispersal constraints also influence small-scale processes and may explain the difference between the potential and the realized niche of species at small-scales. Here we test whether niche size and niche fill differ systematically according to dispersal syndrome within isolated oceanic islands. We expect species with higher dispersal abilities (anemochorous or endozoochorous) will have a higher niche...

Data from: Fine-tuning biodiversity assessments: A framework to pair eDNA metabarcoding and morphological approaches

Cátia Lúcio Pereira, M. Thomas P. Gilbert, Miguel Bastos Araújo & Miguel Graça Matias
Accurate quantification of biodiversity can be demanding and expensive. Although environmental DNA (eDNA) metabarcoding can facilitate biodiversity assessments through non-invasive, cost-efficient, and rapid surveys, the approach struggles to outperform traditional morphological approaches in providing reliable quantitative estimates for surveyed species (e.g., abundance and biomass). We present an integrated methodology for improving biodiversity surveys that pairs eDNA metabarcoding with morphological data, following a series of taxonomic and geographic filters. We demonstrate its power by applying it...

Data from: Physical and ecological isolation contribute to maintain genetic differentiation between fire salamander subspecies

Bernardo Antunes, Guillermo Velo-Antón, David Buckley, Ricardo J. Pereira & Iñigo Martínez-Solano
Landscape features shape patterns of gene flow among populations, ultimately determining where taxa lay along the continuum between panmixia to complete reproductive isolation. Gene flow can be restricted leading to population differentiation in two non-exclusive ways: “physical isolation”, in which geographic distance in combination with the landscape features restricts movement of individuals promoting genetic drift, and “ecological isolation”, in which adaptive mechanisms constrain gene flow between different environments via divergent natural selection. In central Iberia,...

Improved nutritional status may promote an \"asset protection\" reproductive strategy in male rock lizards

Gonzalo Rodriguez-Ruiz, Jesus Ortega, Pilar Lopez, Alfredo Salvador & Jose Martin
Investing in the current reproduction requires diverting energy resources from other metabolic functions, which may compromise future reproduction and lifespan. To solve this trade-off, an individual may consider its labile state to decide how much to invest in current reproduction. We tested experimentally whether the "state quality" of male rock lizards influences their reproductive strategies. To improve the nutritional status of males before the mating season, we captured and supplemented experimental males (N = 20)...

Bayesian morphological clock versus parsimony: An insight into the relationships and dispersal events of postvacuum Cricetidae (Rodentia, Mammalia)

Raquel López-Antoñanzas & Pablo Peláez-Campomanes
Establishing an evolutionary timescale is fundamental for tackling a great variety of topics in evolutionary biology, including the reconstruction of patterns of historical biogeography, coevolution and diversification. However, the tree of life is pruned by extinction and very generally molecular data cannot be gathered for extinct lineages. Methodological challenges have prevented until recently the application of tip-dating Bayesian approaches in morphology-based fossil-only datasets. Herein we present a morphological dataset for a group of cricetid rodents...

Experimentally impaired female condition does not affect biliverdin-based egg colour

Stefania D'Arpa, Iraida Redondo, Eduardo Gómez-Llanos, Diego Gil & Lorenzo Pérez-Rodríguez
It has been proposed that blue-green egg coloration is a condition-dependent female sexual trait that may modify paternal care in a post-mating sexual selection scenario. This pattern may arise because the pigment responsible for eggshell colouration (biliverdin) may be a costly and limited resource, whose availability is linked to female health state. Thus, it can be predicted that females whose condition is compromised should be constrained in their capacity to deposit biliverdin in the eggshell,...

Impacts of ambient temperature and clutch size on incubation behaviour onset in a female-only incubator songbird

David Diez-Méndez, Juan José Sanz & Emilio Barba
Ambient temperature is assumed to be the major cue used by passerines to synchronize their laying and hatching dates to the expected peak of prey availability. While laying eggs, females are still able to fine-tune their hatching date following increasing or decreasing patterns of ambient temperature, mostly via changes in incubation onset. The onset of incubation behaviour in relation to the laying sequence could have later consequences for the duration of the incubation period and...

Genetic and ecomorphological divergence between sympatric Astyanax morphs from Central America

Carlos A. Garita-Alvarado, Marco Garduño-Sánchez, Marta Barluenga & Claudia Patricia Ornelas-García
Intraspecific ecological and morphological polymorphism can promote ecological speciation and the build-up of reproductive isolation. Here, we evaluate correlations among morphology, trophic ecology, and genetic differentiation between two divergent morphs (elongate and deep-body) of the fish genus Astyanax in the San Juan River basin in Central America, to infer the putative evolutionary mechanism shaping this system. We collected the two morphs from three water bodies and analyzed: 1) the correlation between body shape and the...
