Data from: The developmental plasticity and functional significance of an additional sperm storage compartment in female yellow dung fliesMartin A. Schäfer, David Berger, Ralf Jochmann, Wolf U. Blanckenhorn & Luc F. Bussière
1. The mechanistic basis for, and adaptive significance of variation in female sperm storage organs is important for a range of questions concerning sexual selection and speciation, as such variation influences the evolutionary trajectories of male fertilization related traits and may facilitate speciation through its effects on gamete recognition. 2. Female yellow dung flies (Scathophaga stercoraria) usually develop three sperm storage compartments, and this subdivision may be an adaptation for sorting sperm during post-copulatory choice....
Data from: Echinorhynchus salmonis Müller, 1784 (Acanthocephala: Echinorhynchidae) from the Bothnian Bay, Baltic Sea: morphological variability and radial asymmetry of proboscis hooksMatthew T. Wayland, David I. Gibson & Christina Sommerville
Echinorhynchus salmonis is a common parasite of salmoniform and other fishes, occurring in fresh and brackish waters throughout the Holarctic. Presented here is the first analysis of the morphometric and meristic variation in a Palaearctic population of E. salmonis, collected from whitefish Coregonus lavaretus L. and smelt Osmerus eperlaus (L.) from the Bothnian Bay, northern Baltic Sea. Morphological data were compared with published descriptions of congeneric taxa. Nearctic populations of salmonid echinorhynchids considered by some...
Data from: Echinorhynchus brayi n. sp. (Acanthocephala: Echinorhynchidae) from Pachycara crassiceps (Roule) (Zoarcidae), a deep-sea fishMatthew T. Wayland, Christina Sommerville & David I. Gibson
Echinorhynchus brayi n. sp. (Palaeacanthocephala: Echinorhynchidae) is described from Pachycara crassiceps (Roule) (Zoarcidae) from the Porcupine Seabight, Northeast Atlantic. The new species closely resembles E. canyonensis Huffman & Kliever, 1977, a parasite of a Pacific zoarcid, but has longer lemnisci, larger eggs and larger testes. E. brayi n. sp. can be readily differentiated from the ten other Echinorhynchus spp. recorded from deep-sea fishes (E. abyssicola, E. gadi, E. longiproboscis, E. malacocephali, E. melanoglaeae, E. muraenolepisi,...
Data from: Morphometric discrimination of two allozymically diagnosed sibling species of the Echinorhynchus gadi Zoega in Muller complex (Acanthocephala) in the North Sea.Matthew T. Wayland, David I. Gibson & Christina Sommerville
Allozyme electrophoresis was used to detect biological species of the E. gadi complex from gadids from the northern North Sea. A fixed difference at one of nine enzyme loci surveyed confirmed the existence of two reproductively isolated, sympatric species. Mixed infections of two E. gadi spp. (termed A and B) were observed in Gadus morhua and Pollachius virens. E. gadi sp. B was also found in Melanogrammus aeglefinus and Merlangius merlangus. The presence of gravid...
Data from: High genetic diversity and distinctiveness of rear-edge climate relicts maintained by ancient tetraploidisation for Alnus glutinosaOlivier Lepais, Serge D. Muller, Samia Ben Saad-Limam, Mohamed Benslama, Laila Rhazi, Djamila Belouahem-Abed, Amina Daoud-Bouattour, Amor Mokhtar Gammar, Zeineb Ghrabi-Gammar & Cécile Fanny Emilie Bacles
Populations located at the rear-edge of a species’ distribution may have disproportionate ecological and evolutionary importance for biodiversity conservation in a changing global environment. Yet genetic studies of such populations remain rare. This study investigates the evolutionary history of North-African low latitude marginal populations of Alnus glutinosa Gaertn., a European tree species that plays a significant ecological role as a keystone of riparian ecosystems. We genotyped 551 adults from 19 populations located across North Africa...
Element and radionuclide concentrations in representative species of the ICRP's Reference Animals and Plants and associated soils from a forest in north-west EnglandC.L. Barnett, N.A. Beresford, L.A. Walker, M. Baxter, C. Wells & D. Copplestone
This dataset presents the results of an initial sampling exercise conducted at a terrestrial site in northwest England in summer 2010. The following samples of terrestrial Reference Animals and Plants (RAPs) were obtained from an area of circa 0.4 km squared: Molinia caerulea (ICRP RAP Wild Grass defined as Poaceae); Picea sitchensis (ICRP RAP Pine Tree defined as Pinaceae); Apis spp., Bombus spp., Nomada spp. (ICRP RAP Bee defined as Apidea); Apodemus sylvaticus (ICRP RAP...
Data from: Combining animal personalities with transcriptomics resolves individual variation within a wild-type zebrafish population and identifies underpinning molecular differences in brain functionSonia Rey, Sebastian Boltana, Reynaldo Vargas, Nerea Roher & Simon MacKenzie
Resolving phenotype variation within a population in response to environmental perturbation is central to understanding biological adaptation. Relating meaningful adaptive changes at the level of the transcriptome requires the identification of processes that have a functional significance for the individual. This remains a major objective towards understanding the complex interactions between environmental demand and an individual's capacity to respond to such demands. The interpretation of such interactions and the significance of biological variation between individuals...
Data from: Population structure and genetic diversity of native and invasive populations of Solanum rostratum (Solanaceae)Jiali Zhao, Lislie Solís-Montero, Anru Lou & Mario Vallejo-Marín
Aims: We investigate native and introduced populations of Solanum rostratum, an annual, self-compatible plant that has been introduced around the globe. This study is the first to compare the genetic diversity of Solanum rostratum between native and introduced populations. We aim to (1) determine the level of genetic diversity across the studied regions; (2) explore the likely origins of invasive populations in China; and (3) investigate whether there is the evidence of multiple introductions into...
