Environmental filtering and convergent evolution determine the ecological specialisation of subterranean spiders

Stefano Mammola, Miquel Arnedo, Cene Fišer, Pedro Cardoso, Andrea Dejanaz & Marco Isaia
1. Ecological specialisation is an important mechanism enhancing species coexistence within a given community. Yet, unravelling the effect of multiple selective evolutionary and ecological factors leading the process of specialisation remains a key challenge in ecology. Subterranean habitats provide highly replicated experimental arenas in which to disentangle the relative contribution of evolutionary history (convergent evolution vs character displacement) and ecological setting (environmental filtering vs competitive exclusion) in driving community assembly. 2. We tested alternative hypotheses...

Data from: Mitochondrial metagenomics reveals the ancient origin and phylodiversity of soil mites and provides a phylogeny of the Acari

Paula Arribas, Carmelo Andújar, María Lourdes Moraza, Benjamin Linard, Brent C. Emerson & Alfried P. Vogler
High-throughput DNA methods hold great promise for phylogenetic analysis of lineages that are difficult to study with conventional molecular and morphological approaches. The mites (Acari), and in particular the highly diverse soil-dwelling lineages, are among the least known branches of the metazoan Tree-of-Life. We extracted numerous minute mites from soils in an area of mixed forest and grassland in southern Iberia. Selected specimens representing the full morphological diversity were shotgun sequenced in bulk, followed by...

Contribution of genetic versus plastic responses to adaptive patterns in a widespread butterfly along a latitudinal cline

Franziska Günter, Michaël Beaulieu, Kasimir Freiberg, Ines Welzel, Nia Toshkova, Anamarija Žagar, Tatjana Simčič & Klaus Fischer
Understanding how organisms adapt to complex environments is a central goal of evolutionary biology and ecology. This issue is of special interest in the current era of rapidly changing climatic conditions. Here, we investigate clinal variation and plastic responses in life history, morphology, and physiology in the butterfly Pieris napi along a pan-European gradient by exposing butterflies raised in captivity to different temperatures. We found clinal variation in body size, growth rates and concomitant development...

A combined approach of mitochondrial DNA and anchored nuclear phylogenomics sheds light on unrecognized diversity, phylogeny, and historical biogeography of the cascade frogs, genus Amolops (Anura: Ranidae)

Yunhe Wu, Fang Yan, Bryan L. Stuart, Elizabeth Prendini, Chatmongkon Suwannapoom, Hollis A. Dahn, Bao-Lin Zhang, Hong-Xia Cai, Yong-Biao Xu, Ke Jiang, Hong-Man Chen, Alan R. Lemmon, Emily Moriarty Lemmon, Christopher J. Raxworthy, Nikolai L. Orlov, Robert W. Murphy & Jing Che
Amolops is one of the most species-rich genera in Ranidae, with 59 recognized species. This genus currently includes six species groups diagnosed mainly by morphology. Several recent molecular studies indicated that the classification of species groups within Amolops remains controversial, and key nodes in the phylogeny have been inadequately resolved. In addition, the diversity of cascade frogs remains poorly understood, especially for those from incompletely sampled regions. Herein, we investigate the species-level diversity within genus...

Assessing changes in genomic divergence following a century of human mediated secondary contact among wild and captive-bred ducks

Philip Lavretsky, Nancy Rotzel McInerney, Jonathon Mohl, Joshua Brown, Helen James, Kevin McCracken & Robert Fleischer
Along with manipulating habitat, the direct release of domesticated individuals into the wild is a practice used world-wide to augment wildlife populations. We test between possible outcomes of human-mediated secondary contact using genomic techniques at both historical and contemporary time scales for two iconic duck species. First, we sequence several thousand ddRAD-seq loci for contemporary mallards (Anas platyrhynchos) throughout North America, and two domestic mallard-types (i.e., known game-farm mallards and feral Khaki Campbell’s). We show...

A genome-skimmed phylogeny of a widespread bryozoan family, Adeonidae

Russell John Scott Orr, Marianne N. Haugen, Björn Berning, Philip Bock, Robyn Cumming, Wayne Florence, Masato Hirose, Emanuela Di Martino, Mali H. Ramsfjell, Maja M. Sannum, Abigail M. Smith, Leandro M. Vieira, Andrea Waeschenbach & Lee Hsiang Liow
Understanding the phylogenetic relationships among species is one of the main goals of systematic biology. Simultaneously, credible phylogenetic hypotheses are often the first requirement for unveiling the evolutionary history of traits and for modelling macroevolutionary processes. However, many non-model taxa have not yet been sequenced to an extent such that statistically well-supported molecular phylogenies can be constructed for these purposes. Here, we use a genome-skimming approach to extract sequence information for 15 mitochondrial and 2...

Integrating stable isotopes, parasite and ring-reencounter data to quantify migratory connectivity - a case study with Barn Swallows breeding in Switzerland, Germany, Sweden and Finland

Jan Von Rönn, Martin U. Grüebler, Thord Fransson & Fränzi Korner-Nievergelt
Ecosystems around the world are connected by seasonal migration. The migrant animals themselves are influenced by migratory connectivity through effects on the individual and the population level. Measuring migratory connectivity is notoriously difficult due to the simple requirement of data conveying information about the non-breeding distribution of many individuals from several breeding populations. Explicit integration of data derived from different methods increases the precision and the reliability of parameter estimates. We combine ring-reencounter, stable isotope...
