Data from: Deep sequencing of the olfactory epithelium reveals specific chemosensory receptors are expressed at sexual maturity in the European eel Anguilla anguilla

Allison M. Churcher, Peter C. Hubbard, João P. Marques, Adelino V. M. Canário & Mar Huertas
Vertebrate genomes encode a diversity of G protein-coupled receptors (GPCR) that belong to large gene families and are used by olfactory systems to detect chemical cues found in the environment. It is not clear however, if individual receptors from these large gene families have evolved roles that are specific to certain life stages. Here, we used deep sequencing to identify differentially expressed receptor transcripts in the olfactory epithelia (OE) of freshwater, seawater and sexually mature...

Data from: Establishment of a coastal fish in the Azores: recent colonisation or sudden expansion of an ancient relict population?

The processes and timescales associated with ocean-wide changes in the distribution of marine species have intrigued biologists since Darwin’s earliest insights into biogeography. The Azores, a mid-Atlantic volcanic archipelago located >1000 km off the European continental shelf, offers ideal opportunities to investigate phylogeographic colonisation scenarios. The benthopelagic sparid fish known as the common two-banded seabream (Diplodus vulgaris) is now relatively common along the coastline of the Azores archipelago, but was virtually absent before the 1990s....

Data from: Do hatchery-reared sea urchins pose a threat to genetic diversity in wild populations?

Maria Segovia-Viadero, Ester A. Serrão, Juan C. Canteras-Jordana & Mercedes Gonzalez-Wanguemert
In salmonids, the release of hatchery-reared fish has been shown to cause irreversible genetic impacts on wild populations. However, although responsible practices for producing and releasing genetically diverse, hatchery-reared juveniles have been published widely, they are rarely implemented. Here, we investigated genetic differences between wild and early-generation hatchery-reared populations of the purple sea urchin Paracentrotus lividus (a commercially important species in Europe) to assess whether hatcheries were able to maintain natural levels of genetic diversity....

Data from: Seascape drivers of Macrocystis pyrifera population genetic structure in the northeast Pacific

Mattias L. Johansson, Filipe Alberto, Daniel C. Reed, Peter T. Raimondi, Nelson C. Coelho, Mary A. Young, Patrick T. Drake, Christopher A. Edwards, Kyle Cavanaugh, Jorge Assis, Lydia B. Ladah, Tom W. Bell, James A. Coyer, David A. Siegel & Ester A. Serrão
At small spatial and temporal scales, genetic differentiation is largely controlled by constraints on gene flow, while genetic diversity across a species' distribution is shaped on longer temporal and spatial scales. We assess the hypothesis that oceanographic transport and other seascape features explain different scales of genetic structure of giant kelp, Macrocystis pyrifera. We followed a hierarchical approach to perform a microsatellite-based analysis of genetic differentiation in Macrocystis across its distribution in the northeast Pacific....

Data from: Birth date predicts alternative life-history pathways in a fish with sequential reproductive tactics

Teresa Fagundes, Mariana G. Simões, João L. Saraiva, Albert F. H. Ros, David Gonçalves & Rui F. Oliveira
In species with plastic expression of alternative reproductive tactics (ARTs), individuals of the same sex, usually males, can adopt different reproductive tactics depending on factors such as body size. The ‘birth date hypothesis’ proposes that condition-dependent expression of ARTs may ultimately depend on birth date, because individuals born at different times of the year may achieve different sizes and express different reproductive tactics accordingly. However, this has rarely been tested. Here, we tested this hypothesis...

Data from: How integrated are behavioural and endocrine stress response traits? A repeated measures approach to testing the stress coping style model

Kay Boulton, Elsa Couto, Andrew J. Grimmer, Ryan L. Earley, Adelino V.M. Canario, Alastair J. Wilson, Craig A. Walling & Adelino V. M. Canario
It is widely expected that physiological and behavioral stress responses will be integrated within divergent stress-coping styles (SCS) and that these may represent opposite ends of a continuously varying reactive–proactive axis. If such a model is valid, then stress response traits should be repeatable and physiological and behavioral responses should also change in an integrated manner along a major axis of among-individual variation. While there is some evidence of association between endocrine and behavioral stress...
