Data from: The phylogeny of pikas (Ochotona) inferred from a multilocus coalescent approach

José Melo-Ferreira, Ana Lemos De Matos, Helena Areal, Andrey A. Lissovsky, Miguel Carneiro & Pedro J. Esteves
The clarification of the systematics of pikas (genus Ochotona) has been hindered by largely overlapping morphological characters among species and the lack of a comprehensive molecular phylogeny. Here we estimate the first multilocus phylogeny of the genus to date, by analysing 12 nuclear DNA markers (total of 7.5 Kb) in 11 species of pikas from the four classified subgenera (Pika, Ochotona, Lagotona and Conothoa) using a multispecies coalescent-based framework. The species-tree confirmed the subgeneric classification...

Drosophila (Drosophila) nigrosparsa is a habitat specialist restricted to the European montane/alpine zone (Bächli 2008). Mountain biodiversity is considered highly vulnerable to ongoing climate warming (IPCC 2013), and organisms at high altitudes have only limited possibility to shift to cooler habitats at elevations above (Pertoldi & Bach 2007). For such species, rapid evolution may offer a solution for long-term survival. We are establishing D. nigrosparsa as a model system to test the extent and tempo...

Data from: Drivers of power line use by white storks: a case study of birds nesting on anthropogenic structures

Francisco Moreira, Ricardo C. Martins, Ines Catry & Marcello D'Amico
1. Anthropogenic structures are mainly known to have negative impacts on wildlife populations but sometimes arethey can be beneficial. Power lines are a main driver of bird mortality through collision or electrocution, but electricity pylons are also commonly used for nest building by some species. Birds and nests cause power outages that need to be tackled by electricity companies. However, the use of pylons by threatened species provides an opportunity for conservation purposes. 2. In...

Data from: Agriculture shapes the trophic niche of a bat preying on multiple pest arthropods across Europe: evidence from DNA metabarcoding

Ostaizka Aizpurua, Ivana Budinski, Panagiotis Georgiakakis, Shyam Gopalakrishnan, Carlos Ibáñez, Vanessa Mata, Hugo Rebelo, Danilo Russo, Farkas Szodoray-Parádi, Violeta Zhelyazkova, Vida Zrncic, M. Thomas P. Gilbert & Antton Alberdi
The interaction between agricultural production and wildlife can shape, and even condition, the functioning of both systems. In this study we i) explored the degree to which a widespread European bat, namely the common bent-wing bat Miniopterus schreibersii, consumes crop-damaging insects at a continental scale, and ii) tested whether its dietary niche is shaped by the extension and type of agricultural fields. We employed a dual-primer DNA metabarcoding approach to characterise arthropod 16S and COI...

Data from: No evidence for Fabaceae Gametophytic self-incompatibility being determined by Rosaceae, Solanaceae, and Plantaginaceae S-RNase lineage genes

Bruno Aguiar, Jorge Vieira, Ana E. Cunha & Cristina P. Vieira
Background: Fabaceae species are important in agronomy and livestock nourishment. They have a long breeding history, and most cultivars have lost self-incompatibility (SI), a genetic barrier to self-fertilization. Nevertheless, to improve legume crop breeding, crosses with wild SI relatives of the cultivated varieties are often performed. Therefore, it is fundamental to characterize Fabaceae SI system(s). We address the hypothesis of Fabaceae gametophytic (G)SI being RNase based, by recruiting the same S-RNase lineage gene of Rosaceae,...

Data from: Evolution at a different pace: distinctive phylogenetic patterns of cone snails from two ancient oceanic archipelagos

Regina L. Cunha, Fernando P. Lima, Manuel J. Tenorio, Ana A. Ramos, Rita Castilho & Suzanne T. Williams
Ancient oceanic archipelagos of similar geological age are expected to accrue comparable numbers of endemic lineages with identical life history strategies, especially if the islands exhibit analogous habitats. We tested this hypothesis using marine snails of the genus Conus from the Atlantic archipelagos of Cape Verde and Canary Islands. Together with Azores and Madeira, these archipelagos comprise the Macaronesia biogeographic region and differ remarkably in the diversity of this group. More than 50 endemic Conus...

Data from: Real-time assessment of hybridization between wolves and dogs: combining non-invasive samples with ancestry informative markers

Raquel Godinho, José Vicente López-Bao, Diana Castro, Luís Llaneza, Susana Lopes, Pedro Silva & Nuno Ferrand
Wolves and dogs provide a paradigmatic example of the ecological and conservation implications of hybridization events between wild and domesticated forms. However, our understanding of such implications has been traditionally hampered by both high genetic similarity and the difficulties in obtaining tissue samples (TS), which limit our ability to assess ongoing hybridization events. To assess the occurrence and extension of hybridization in a pack of wolf-dog hybrids in Northwestern Iberia, we compared the power of...

Optimising bat bioacoustic surveys in human-modified neotropical landscapes

Adrià López-Baucells, Natalie Yoh, Ricardo Rocha, Paulo Bobrowiec, Jorge Palmeirim & Christoph Meyer
During the last decades, the use of bioacoustics as a non-invasive and cost-effective sampling method has greatly increased worldwide. For bats, acoustic surveys have long been known to complement traditional mist-netting, however, appropriate protocol guidelines are still lacking for tropical regions. Establishing the minimum sampling effort needed to detect ecological changes in bat assemblages (e.g., activity, composition and richness) is crucial in view of workload and project cost constraints, and because detecting such changes must...

Understanding the local drivers of beta-diversity patterns under climate change: The case of seaweed communities in Galicia, North West of the Iberian Peninsula

Cândida Gomes Vale, Francisco Arenas, Rodolfo Barreiro & Cristina Piñeiro-Corbeira
Aim: To understand spatial-temporal changes (beta-diversity) in coastal communities and their drivers in the context of climate change. Coastal ecosystems are extremely exposed and dynamic, where changes in seaweed assemblages have been associated with changing water temperatures. However, at the local scale, the effects of changes in the upwelling events and related stressors seek further exploration. Location: Galicia rías, North West of the Iberian Peninsula Methods: Using data collected in 42 sampling localities in Galicia...

AFLP and geometric morphometrics for Littorina fabalis

Juan Galindo & Rui Faria
Low dispersal marine intertidal species facing strong divergent selective pressures associated with steep environmental gradients have a great potential to inform us about local adaptation and reproductive isolation. Among these, gastropods of the genus Littorina offer a unique system to study parallel phenotypic divergence resulting from adaptation to different habitats related with wave exposure. In this study, we focused on two Littorina fabalis ecotypes from Northern European shores and compared the patterns of habitat-related phenotypic...

Data from: Climatic refugia boosted allopatric diversification in Western Mediterranean vipers

Fernando Martínez-Freiría, Inês Freitas, Marco A. L. Zuffi, Philippe Golay, Sylvain Ursenbacher & Guillermo Velo-Antón
Abstract: Aim: to understand the role of climate in fostering diversification, this study reconstructs the historical biogeography of Western Mediterranean vipers Location: Western Mediterranean Basin Taxon: Vipera aspis and V. latastei-monticola complex Methods: phylogeographic analyses were performed over mitochondrial (three genes) and nuclear sequences (two genes), extensively covering species ranges. A total of 4,056 records were assigned to genetic units, using interpolations of genetic data, to test phylogenetic niche conservatism, under a 3D hypervolume approach,...

Data from: Reliable wolf-dog hybrid detection in Europe using a reduced SNP panel developed for non-invasively collected samples

Jenni Harmoinen, Alina Von Thaden, Jouni Aspi, Laura Kvist, Berardino Cocchiararo, Anne Jarausch, Andrea Gazzola, Teodora Sin, Hannes Lohi, Marjo Hytönen, Ilpo Kojola, Astrid Vik Stronen, Romolo Caniglia, Federica Mattucci, Marco Galaverni, Raquel Godinho, Aritz Ruiz-González, Ettore Randi, Violeta Muñoz-Fuentes & Carsten Nowak
Background: Understanding the processes that lead to hybridization of wolves and dogs is of scientific and management importance, particularly over large geographical scales, as wolves can disperse great distances. However, a method to efficiently detect hybrids in routine wolf monitoring is lacking. Microsatellites offer only limited resolution due to the low number of markers showing distinctive allele frequencies between wolves and dogs. Moreover, calibration across laboratories is time-consuming and costly. In this study, we selected...

Reduced sexual size dimorphism in a pipefish population where males do not prefer larger females

Nuno Monteiro, Mário Cunha, Nídia Macedo, Jonathan Wilson, Gunilla Rosenqvist & Anders Berglund
Within a species’ distribution, populations are often exposed to diverse environments and may thus experience different sources of both natural and sexual selection. These differences are likely to impact the balance between costs and benefits to individuals seeking reproduction, thus entailing evolutionary repercussions. Here, we look into an unusual population (Baltic Sea) of the broadnosed pipefish, Syngnathus typhle, where males do not seem to select females based on size and hypothesise that this pattern may...

Data from: Genetic identification of Iberian rodent species using both mitochondrial and nuclear loci: application to non-invasive sampling

Soraia Barbosa, Joana Pauperio, Jeremy B. Searle & Paulo C. Alves
Species identification through non-invasive sampling is increasingly used in animal conservation genetics, given that it obviates the need to handle free-living individuals. Non-invasive sampling is particularly valuable for elusive and small species such as rodents. Although rodents are not usually assumed to be the most obvious target for conservation, of the 21 species or near-species present in Iberia, three are considered endangered and declining while several others are poorly studied. Here we develop a genetic...

Data from: Conservation implications of the evolutionary history and genetic diversity hotspots of the snowshoe hare

Ellen Cheng, Karen E. Hodges, José Melo-Ferreira, Paulo C. Alves & L. Scott Mills
With climate warming, the ranges of many boreal species are expected to shift northward and to fragment in southern peripheral ranges. To understand the conservation implications of losing southern populations, we examined range-wide genetic diversity of the snowshoe hare (Lepus americanus), an important prey species that drives boreal ecosystem dynamics. We analysed microsatellite (8 loci) and mitochondrial DNA sequence (cytochrome b and control region) variation in almost 1000 snowshoe hares. A hierarchical structure analysis of...
