Data from: Exploring seascape genetics and kinship in the reef sponge Stylissa carteri in the Red Sea

Emily C. Giles, Pablo Saenz-Agudelo, Nigel E. Hussey, Timothy Ravasi & Michael L. Berumen
A main goal of population geneticists is to study patterns of gene flow to gain a better understanding of the population structure in a given organism. To date most efforts have been focused on studying gene flow at either broad scales to identify barriers to gene flow and isolation by distance or at fine spatial scales in order to gain inferences regarding reproduction and local dispersal. Few studies have measured connectivity at multiple spatial scales...

Data from: Energy expenditure and body size are targets of natural selection across a wide geographic range, in a terrestrial invertebrate

José Luis Bartheld, Juan Diego Gaitán-Espitia, Paulina Artacho, Cristian Salgado-Luarte, Ernesto Gianoli & Roberto F. Nespolo
One of the central questions in evolutionary ecology is how different functional capacities impact fitness, and how it varies across populations. For instance, do phenotypic attributes influence fitness similarly across geographic gradients? Which traits (physiological, morphological, life history) are most likely to be targets of natural selection? Do particular combinations of traits maximize fitness? In a semi-natural experiment, we analyzed introduced populations of an invasive species, the garden snail (Cornu aspersum) in Chile, which show...

Data from: Seascape genetics along environmental gradients in the Arabian Peninsula: insights from ddRAD sequencing of anemonefishes

Pablo Saenz-Agudelo, Joseph D. DiBattista, Marek J. Piatek, Michelle R. Gaither, Hugo B. Harrison, Gerrit B. Nanninga & Michael L. Berumen
Understanding the processes that shape patterns of genetic structure across space is a central aim of landscape genetics. However, it remains unclear how geographic features and environmental variables shape gene flow, particularly for marine species in large complex seascapes. Here, we evaluated the genomic composition of the two-band anemonefish Amphiprion bicinctus across its entire geographic range in the Red Sea and Gulf of Aden, as well as its close relative, Amphiprion omanensis endemic to the...

Data from: Linking macro-trends and micro-rates: re-evaluating micro-evolutionary support for Cope’s rule

Kiyoko M. Gotanda, Cristián Correa, Martin M. Turcotte, Gregor Rolshausen & Andrew P. Hendry
Cope's rule, wherein a lineage increases in body size through time, was originally motivated by macro-evolutionary patterns observed in the fossil record. More recently, some authors have argued that evidence exists for generally positive selection on individual body size in contemporary populations, providing a micro-evolutionary mechanism for Cope's rule. If larger body size confers individual fitness advantages as the selection estimates suggest, thereby explaining Cope's rule, then body size should increase over micro-evolutionary time scales....

Data from: The oldest, slowest forests in the world? Exceptional biomass and slow carbon dynamics of Fitzroya cupressoides temperate rainforests in southern Chile

Rocio B. Urrutia-Jalabert, Yadvinder Malhi, Antonio Lara & Rocio Urrutia-Jalabert
Old-growth temperate rainforests are, per unit area, the largest and most long-lived stores of carbon in the terrestrial biosphere, but their carbon dynamics have rarely been described. The endangered Fitzroya cupressoides forests of southern South America include stands that are probably the oldest dense forest stands in the world, with long-lived trees and high standing biomass. We assess and compare aboveground biomass, and provide the first estimates of net primary productivity (NPP), carbon allocation and...

Data from: Contrasting definitive hosts as determinants of the genetic structure in a parasite with complex life cycle along the Southeastern Pacific

Zambra López, Leyla Cárdenas, Fernando Runil & M. Teresa González
The spatial genetic structure (and gene flow) of parasites with complex life cycles, such as digeneans, has been attributed mainly to the dispersion ability of the most mobile host, which most often corresponds to the definitive host (DH). In this study, we compared the genetic structure and diversity of adult Neolebouria georgenascimentoi in two fish species (DHs) that are extensively distributed along the Southeastern Pacific (SEP). The analysis was based on the cytochrome oxidase subunit...

Data from: The role of marine reserves in the replenishment of a locally-impacted population of anemonefish on the Great Barrier Reef

Mary C. Bonin, Hugo B. Harrison, David H. Williamson, Ashley J. Frisch, Pablo Saenz-Agudelo, Michael L. Berumen & Geoffrey P. Jones
The development of parentage analysis to track the dispersal of juvenile offspring has given us unprecedented insight into the population dynamics of coral reef fishes. These tools now have the potential to inform fisheries management and species conservation, particularly for small fragmented populations under threat from exploitation and disturbance. In this study we resolve patterns of larval dispersal for a population of the anemonefish Amphiprion melanopus in the Keppel Islands (southern Great Barrier Reef). Habitat...

Data from: Quantification of correlational selection on thermal physiology, thermoregulatory behavior and energy metabolism in lizards

Paulina Artacho, Julia Saravia, Beatriz Decencière Ferrandière, Samuel Perret & Jean-François Le Galliard
Phenotypic selection is widely accepted as the primary cause of adaptive evolution in natural populations, but selection on complex functional properties linking physiology, behavior, and morphology has been rarely quantified. In ectotherms, correlational selection on thermal physiology, thermoregulatory behavior, and energy metabolism is of special interest because of their potential coadaptation. We quantified phenotypic selection on thermal sensitivity of locomotor performance (sprint speed), thermal preferences, and resting metabolic rate in captive populations of an ectothermic...

Data from: Heat tolerance in Drosophila subobscura along a latitudinal gradient: contrasting patterns between plastic and genetic responses

Luis E. Castañeda, Enrico L. Rezende & Mauro Santos
Susceptibility to global warming relies on how thermal tolerances respond to increasing temperatures through plasticity or evolution. Climatic adaptation can be assessed examining the geographic variation in thermal-related traits. We studied latitudinal patterns in heat tolerance in Drosophila subobscura reared at two temperatures. We used four static stressful temperatures to estimate the thermal death time curves (TDT), and two ramping assays with fast and slow heating rates. TDT curves allow estimating the critical thermal maximum...

Data from: Does sex-biased dispersal account for the lack of geographic and host-associated differentiation in introduced populations of an aphid parasitoid?

Francisca Zepeda-Paulo, Blas Lavandero, Frédérique Mahéo, Emilie Dion, Yannick Outreman, Jean-Christophe Simon & Christian C. Figueroa
Host recognition and use in female parasitoids strongly relies on host fidelity, a plastic behavior which can significantly restrict the host preferences of parasitoids, thus reducing the gene flow between parasitoid populations attacking different insect hosts. However, the effect of migrant males on the genetic differentiation of populations has been frequently ignored in parasitoids, despite its known impact on gene flow between populations. Hence, we studied the extent of gene flow mediated by female and...
