Data from: Zoogeography of epigean freshwater Amphipoda (Crustacea) in Romania: fragmented distributions and wide altitudinal variability

Denis Copilaș-Ciocianu, Michal Grabowski, Lucian Parvulescu & Adam Petrusek
Inland epigean freshwater amphipods of Romania are diverse and abundant for this region has a favourable geographical position between the Balkans and the Black Sea. Excluding Ponto-Caspian species originating in brackish waters and freshwater subterranean taxa, there are 11 formally recognized epigean freshwater species recorded from this country. They belong to 3 genera, each representing a different family: Gammarus (Gammaridae, 8 species or species complexes), Niphargus (Niphargidae, 2 epigean species) and Synurella (Crangonyctidae, one species)....

Data from: Leukocyte profiles are associated with longevity and survival, but not migratory effort: a comparative analysis of shorebirds

Piotr Minias, Radosław Włodarczyk & Włodzimierz Meissner
1. Assessment of leukocyte profiles has become an increasingly popular tool in the fields of ecology and ecophysiology. The ratio of heterophils to lymphocytes (H/L ratio) is of special utility, as it reflects physiological adaptation of an organism to cope either with an infection through injury (via heterophils) or a communicable disease (via lymphocytes). Thus, elevated H/L ratios may constitute an adaptation to risky environments (i.e. associated with high risk of injury). While intra-population variation...

Data from: Ecology and evolution of blood oxygen-carrying capacity in birds

Piotr Minias
Blood oxygen-carrying capacity is one of important determinants of oxygen amounts supplied to the tissues per unit time and plays a key role in oxidative metabolism. In wild vertebrates, blood oxygen-carrying capacity is most commonly measured with the total blood haemoglobin concentration (Hb) and haematocrit (Hct), which is the volume percentage of red blood cells in blood. Here, I used published estimates of avian Hb and Hct (nearly one thousand estimates from 300 species) to...

Data from: Evolution of heterophil/lymphocyte ratios in response to ecological and life-history traits: a comparative analysis across the avian tree of life

Piotr Minias
1. Lymphocytes and heterophils are the two most abundant leukocyte types, which play a major role in adaptive and innate immune defence, respectively. The ratio of heterophils to lymphocytes (H/L ratio) may reflect a readiness to cope with infection through injury (via heterophils) rather than with a communicable disease (via lymphocytes). Since elevated H/L ratio constitutes a corticosterone-mediated response to external stressors, this trait is generally acknowledged as the robust measure of physiological stress in...

Avian MHC copy number variation is associated with helminth richness

Piotr Minias, Jorge Gutiérrez & Peter Dunn
Genes of the Major Histocompatibility Complex (MHC) play a key role in the adaptive immunity of vertebrates, as they encode receptors responsible for recognition of antigens. Evolutionary history of the MHC proceeded through numerous gene duplications, which increases the spectrum of pathogens recognized by individuals. Although pathogen-mediated selection is believed to be a primary driver of MHC expansion over evolutionary times, empirical evidence for this association is virtually lacking. Here, we used an extensive dataset...

High MHC diversity confers no advantage for phenotypic quality and reproductive performance in a wild bird

Ewa Pikus, Peter Dunn & Piotr Minias
Genes of the major histocompatibility complex (MHC) encode antigen binding molecules and are an integral part of the acquired immune response of vertebrates. In general, high individual MHC diversity is expected to increase fitness by broadening the spectrum of pathogens recognized by the immune system, in accordance with the heterozygote advantage mechanism. On the other hand, the optimality hypothesis assumes that individuals with optimal (intermediate), rather than maximum diversity of the MHC will achieve the...

Data from: Unveiling tipping points in long-term ecological records from Sphagnum-dominated peatlands

Mariusz Lamentowicz, Mariusz Gałka, Katarzyna Marcisz, Michał Słowiński, Kajukało-Drygalska Kajukało, Milva Druguet Dayras & Vincent E.J. Jassey
Unveiling past tipping points is a prerequisite for a better understanding of how individual species and entire ecosystems will respond to future climate change. Such knowledge is key for the implementation of biodiversity conservation. We identify the relationships between peatland vegetation and hydrological conditions over the past 2000 years using macrofossils, testate amoebae-based quantitative hydrological reconstructions, and Sphagnum-moss functional traits from seven Polish peatland records. Using threshold indicator taxa analysis (TITAN), we discovered that plant...

Data from: Inter-colony variation in foraging flight characteristics of black-headed gulls Chroicocephalus ridibundus during the incubating period

Dariusz Jakubas, Piotr Indykiewicz, Jarosław Kowalski, Tomasz Iciek & Piotr Minias
Using GPS-loggers, we examined the influence of colony, sex, and bird identity on foraging flight characteristics of black-headed gulls Chroicocephalus ridibundus during the incubation period. We studied tracks of 36 individuals breeding in one urban and two rural colonies in Poland. Birds from both rural colonies performed the furthest flights (mean 8-12 km, up to 27 km) foraging mainly in agricultural areas. Gulls from the urban colony performed shorter flights (median 5 km, up to...

Data from: Thriving in a hostile world: insights from the dietary strategy of two allopatric, closely-related tepui summit endemic amphibians

Philippe Kok, Tessa Broholm & Dietrich Mebs
To date, there has been no published investigation on the trophic diversity in any tepui summit vertebrate. In this paper we analysed the dietary composition of a tepui summit endemic toad, Oreophrynella quelchii from Roraima-tepui, and compared it with that of O. nigra, to examine to what extent diet differs between these two sister species across isolated, although neighbouring, tepui tops. The digestive tracts of a total of 197 toads were dissected: 111 from O....

Data from: Morphological vs. molecular delineation of taxa across montane regions in Europe: the case study of Gammarus balcanicus Schäferna, 1922 (Crustacea: Amphipoda)

Tomasz Mamos, Remi Wattier, Aneta Majda, Boris Sket & Michał Grabowski
Mountainous areas are characterized by substantial biodiversity and endemicity due to their complex geological history and habitat fragmentation. Hence, it can be assumed that particularly high species richness can be found in organisms with limited dispersal capabilities that inhabit mountain streams. A number of scientific papers focus on molecular phylogeography or traditional taxonomy of species or species groups inhabiting such habitats. However, there is a lack of studies that integrate morphological and molecular data to...

Data from: The legacy of a vanished sea: a high level of diversification within a European freshwater amphipod species complex driven by 15 My of Paratethys regression

Tomasz Mamos, Remi Wattier, Artur Burzyński & Michał Grabowski
The formation of continental Europe in the Neogene was due to the regression of the Tethys Ocean and of the Paratethys Sea. The dynamic geology of the area and repetitious transitions between marine and freshwater conditions presented opportunities for the colonization of newly emerging hydrological networks and diversification of aquatic biota. Implementing mitochondrial and nuclear markers in conjunction with a large-scale sampling strategy, we investigated the impact of this spatiotemporal framework on the evolutionary history...

Contrasting patterns of Campylobacter and Salmonella distribution in wild birds: a comparative analysis

Piotr Minias
Transmission of gastrointestinal bacteria, Campylobacter spp. and Salmonella spp., from wild birds may have serious consequences for human health and poultry industry. Despite this, our knowledge on the distribution of these bacteria in wild avian populations is limited. Since both genera markedly differ in their pathogenicity in wild birds (Campylobacter is largely non-pathogenic, while Salmonella is a major pathogen), I expected that their occurrence and modes of transmission can be associated with different ecological and...

Effect of heat shock on the antioxidant system of round goby

Dagmara Błońska
Monitoring oxidative stress biomarkers has become a powerful and common tool to estimate organismal condition and response to endogenous and environmental factors. In the present study, we used round goby (Neogobius melanostomus) from non-native European populations, as a model species to test sex differences in oxidative stress biomarkers. Considering sex differences in reproductive investment, we hypothesized that males would display lower resistance to abiotic stress. Fish were exposed to a heat shock (temperature elevated by...

Data from: Avian developmental rates are constrained by latitude and migratoriness – a global analysis

Piotr Minias & Radosław Włodarczyk
Aim: It has long been recognized that tropical bird species demonstrate a wide range of traits characteristic for slow life histories, as indicated by lower investment in reproduction, slower senescence or slower physiological pace of life. Nevertheless, evidence for latitudinal variation in avian developmental rates has, so far, been inconclusive and based on limited geographic or phylogenetic sampling. The aim of this study was to test for global associations of avian developmental rates with latitude...

Evolution of a conspicuous melanin-based ornament in gulls Laridae

Piotr Minias & Tomasz Janiszewski
Melanin- and carotenoid-based ornaments often signal different aspects of individual quality or similar aspects under different environmental conditions and, thus, they may become evolutionarily integrated into a composite sexual trait. On the other hand, functionally and developmentally different characters (e.g. coloration characters of different developmental origin) are more likely to evolve independently from each other than more similar traits. Here, we examined evolutionary correlations between the occurrence of a conspicuous melanin-based ornament (hood) and carotenoid-based...

Food resource partitioning between juvenile and mature weatherfish Misgurnus fossilis

Kacper Pyrzanowski
This study represents a description of the diet composition of one of the largest European cobitids, the weatherfish Misgurnus fossilis. Specimens were collected in a drainage canal, representing a typical habitat for weatherfish, and with gut content analysis conducted with regard to individual total length and maturity stage. Overall, the weatherfish diet mainly consisted of Copepoda, Cladocera, Oligochaeta, Crustacea (Asellus aquaticus), Chironomidae, detritus and insect larvae. To evaluate size-related patterns of resource use, fish were...

Sex chromosome differentiation via changes in the Y chromosome repeat landscape in African annual killifishes Nothobranchius furzeri and N. kadleci

Jana Štundlová, Monika Kreklová, Karolína Lukšíková, Anna Voleníková, Tomáš Pavlica, Marie Altmanová, Martin Reichard, Christoph Englert, Silke Förste, Martina Dalíková, Šárka Pelikánová, Anatolie Marta, Sergey A. Simanovsky, Matyáš Hiřman, Marek Jankásek, Tomáš Dvořák, Joerg Bohlen, Petr Ráb, Petr Nguyen & Alexandr Sember
Repetitive DNA represents an important driver of sex chromosome differentiation. Yet repetitive sequences tend to be misrepresented or overlooked in genomic studies. We analysed repetitive landscape of sex chromosomes in several populations of a turquoise killifish Nothobranchius furzeri and its sister species N. kadleci (Teleostei: Nothobranchiidae), representatives of African annual killifishes with high rate of karyotype and sex chromosome evolution. We combined bioinformatic analyses of repeatome with molecular cytogenetic techniques such as comparative genomic hybridization,...

Data from: Contrasting evolutionary histories of MHC class I and class II loci in grouse - effects of selection and gene conversion

Piotr Minias, Zachary W. Bateson, Linda A. Whittingham, Jeff A. Johnson, Sara Oyler-McCance & Peter O. Dunn
Genes of the major histocompatibility complex (MHC) encode receptor molecules that are responsible for recognition of intra- and extra-cellular pathogens (class I and class II genes, respectively) in vertebrates. Given the different roles of class I and II MHC genes, one might expect the strength of selection to differ between these two classes. Different selective pressures may also promote different rates of gene conversion at each class. Despite these predictions, surprisingly few studies have looked...

Immunocompetent birds choose larger breeding colonies

Joanna Drzewińska-Chańko, Radosław Włodarczyk, Adrian Gajewski, Karolina Rudnicka, Peter Dunn & Piotr Minias
The optimal size of social groups may vary between individuals, depending on their phenotypic traits, such as dominance status, age, or personality. Larger social groups often enhance transmission rates of pathogens and should be avoided by individuals with poor immune defenses. In contrast, more immunocompetent individuals are expected to take advantage of larger group sizes (e.g. better protection, information transfer) with smaller extra costs from pathogen or parasite pressure. Here, we hypothesized that immunocompetence may...

Salamanders reveal novel trajectories of amphibian MHC evolution

Piotr Minias, Gemma Palomar, Katarzyna Dudek & Wiesław Babik
Genes of the Major Histocompatibility Complex (MHC) code for immune proteins that are crucial for pathogen recognition in vertebrates. MHC research in non-model taxa has long been hampered by its genomic complexity that makes the locus-specific genotyping challenging. The recent progress in sequencing and genotyping methodologies allows an extensive phylogenetic coverage in studies of MHC evolution. Here, we analysed the peptide-binding region of MHC class I in 30 species of salamanders from six families representative...
