What defines insularity for plants in edaphic islands?

Francisco Emmanuel Méndez Castro, Luisa Conti, Milan Chytrý, Borja Jimenez-Alfaro, Michal Hajek, Michal Horsák, David Zeleny, Marco Malavasi & Gianluigi Ottaviani
The Theory of Island Biogeography postulates that size and isolation are key drivers of biodiversity on islands. This theory has been applied not only to true (e.g. oceanic) islands but also to terrestrial island-like systems (e.g. edaphic islands). Recently, a debate has opened as to whether terrestrial island-like systems function like true islands. However, identifying the effect of insularity in terrestrial systems is conceptually and methodologically challenging because recognizing species source(s) and measuring isolation is...

Chromosome evolution and the genetic basis of agronomically important traits in greater yam

Jessen Bredeson, Jessica Lyons, Ibukun Oniyinde, Nneka Okereke, Olufisayo Kolade, Ikenna Nnabue, Nneka Okereke, Christian Nwadili, Eva Hribova, Matthew Parker, Jeremiah Nwogha, Shengqiang Shu, Joseph Carlson, Robert Kariba, Samuel Muthemba, Katarzyna Knop, Geoffrey Barton, Anna Sherwood, Antonio Lopez-Montes, Robert Asiedu, Ramni Jamnadass, Alice Muchugi, David Goodstein, Chiedozie Egesi, Jonathan Featherston … & Daniel Rokhsar
The nutrient-rich tubers of the greater yam, Dioscorea alata L., provide food and income security for millions of people around the world. Despite its global importance, however, greater yam remains an ‘orphan crop.’ Here we address this resource gap by presenting a highly contiguous chromosome-scale genome assembly of D. alata combined with a dense genetic map derived from African breeding populations. The genome sequence reveals an ancient allotetraploidization in the Dioscorea lineage, followed by extensive...

ddRAD-derived genotypes of Centaurea jacea and Betonica officinalis populations from the White Carpathians

Johannes Höfner, Theresa Klein-Raufhake, Christian Lampei, Ondrej Mudrak, Anna Bucharova & Walter Durka
Ecological restoration and plant re-introductions aim to create plant populations that are genetically similar to natural populations to preserve the regional gene pool, yet genetically diverse to allow adaptation to a changing environment. For this purpose, seeds for restoration are increasingly sourced from multiple populations in the target region. However, it has only rarely been tested whether using regional seed indeed leads to genetically diverse restored populations which are genetically similar to natural populations. We...

Land-use and elevation interact to shape bird functional and phylogenetic diversity and structure: Implications for designing optimal agriculture landscapes

Rachakonda Sreekar, Xingfeng Si, Katerina Sam, Jiajia Liu, Salindra Dayananda, Uromi Goodale, Sarath Kotagama & Eben Goodale
Conversion of rainforests into agriculture resulted in massive changes in species diversity and community structure. Although the conservation of the remaining rainforests is of utmost importance, identifying and creating biodiversity-friendly agriculture landscape is vital for preserving biodiversity and their functions. Biodiversity studies in agriculture have often been conducted at low elevations. In this study, we compared the functional diversity (FD), phylogenetic diversity (PD), and community structure of birds along an interacting gradient of land-use (protected...

Global maps of current (1979-2013) and future (2061-2080) habitat suitability probability for 1,485 European endemic plant species

Robin Pouteau, Idoia Biurrun, Caroline Brunel, Milan Chytrý, Wayne Dawson, Franz Essl, Trevor Fristoe, Rense Haveman, Carsten Hobohm, Florian Jansen, Holger Kreft, Jonathan Lenoir, Bernd Lenzner, Carsten Meyer, Jesper Erenskjold Moeslund, Jan Pergl, Petr Pyšek, Jens-Christian Svenning, Wilfried Thuiller, Patrick Weigelt, Thomas Wohlgemuth, Qiang Yang & Mark Van Kleunen
Aims: The rapid increase in the number of species that have naturalized beyond their native range is among the most apparent features of the Anthropocene. How alien species will respond to other processes of future global changes is an emerging concern and remains largely misunderstood. We therefore ask whether naturalized species will respond to climate and land-use change differently than those species not yet naturalized anywhere in the world. Location: Global Methods: We investigated future...

The species richness-productivity relationship varies among regions and productivity estimates, but not with spatial resolution

Aleš Lisner, Gianluigi Ottaviani, Jitka Klimešová, Ondřej Mudrák, Jana Martínková & Jan Lepš
The relationship between species richness and productivity (SRPR) has been a long-studied and hotly debated topic in ecology. Different studies have reported different results with variable shapes (i.e. unimodal, linear) and directions (i.e. positive, negative) of SRPRs depending on spatial grain (i.e. size of sampling unit for species richness), productivity estimates, and study extent. In this study, we quantified the effect of multiple estimates of productivity (aboveground, belowground and total biomass, and various measures of...

Malinae481 exonic probe set

Christoph Dobeš, Roswitha Schmickl & Roman Ufimov
The subtribe Malinae (Rosaceae) comprises close to 1,000 species and up to 30 genera. It is defined, among other characters, by a derived base chromosome number of x = 17. A parsimonious pattern of chromosome breakage and fusion explains the derivation of the x = 17 karyotype from a polyploidisation event of two x = 9 genomes. High collinearity between the genetic and physical maps of Pyrus and Malus as well as their identical karyotypes...

Inter-annual repeatability and age-dependent changes in plasma testosterone levels in a longitudinally monitored free-living passerine bird

Martin Těšický, Tereza Krajzingrová, Jiří Eliáš, Hana Velová, Jana Svobodová, Petra Bauerová, Tomáš Albrecht & Michal Vinkler
While seasonal trends in testosterone levels are known from cross-cohort studies, data on testosterone inter-annual individual repeatability in wild birds are rare. Also, our understanding of hormonal age-dependent changes in testosterone levels is limited. We assessed plasma testosterone levels in 105 samples originating from 49 repeatedly captured free-living great tits (Parus major) sampled during the nesting to investigate their relative long-term repeatability and within-individual changes. Furthermore, we examined the inter-annual repeatability of condition-related traits (carotenoid-...

Sex differences in killifish

Martin Reichard
Males often experience shorter lifespans than females. Despite extensive research, it is poorly understood how lifespan differences between the sexes are modulated by an interplay among genetic, environmental and social factors. Using four African annual killifish species, we combined comparative data from sex ratios in natural populations with experimental results on sex differences in lifespan and aging in replicated captive populations. In the wild, females consistently outlived males. In socially-housed experimental groups, this sex-specific survival...

Connectivity and succession of open structures as a key to sustaining light-demanding biodiversity in deciduous forests

Petr Kozel, Pavel Sebek, Michal Platek, Jiri Benes, Michal Zapletal, Miroslav Dvorsky, Vojtech Lanta, Jiri Dolezal, Radek Bace, Borivoj Zbuzek & Lukas Cizek
1. European forests are facing a rapid decline of light-demanding biota. This has prompted active interventions to re-establish and maintain partial habitat openness in protected areas. Managers of protected areas, however, need substantially more scientific evidence to support their decisions on where, when, and how to intervene. 2. We investigated the importance of spatial continuity of open forest habitats in different years of succession, using six pairs of experimental clearings established in the formerly open,...

High diversity of mites (Acari: Oribatida, Mesostig-mata) supports the high conservation value of a broadleaf forest in Eastern Norway

Anna Seniczak, Stanisław Seniczak, Josef Starý, Sławomir Kaczmarek, Bjarte Jordal, Jarosław Kowalski, Steffen Roth, Per Djursvoll & Thomas Bolger
Broadleaf forests are critical habitats for biodiversity and this biodiversity is in turn essential for their proper functioning. Mites (Acari) are a numerous and functionally essential component of these forests. We report the diversity of two important groups, Oribatida and Mesostigmata, in a broadleaf forest in Eastern Norway which is considered to be a biodiversity hotspot. Eighteen samples, each 500 cm3, were collected from diverse microhabitats (moss on ground, lichens on tree twigs lying on...

Midpoint attractor models resolve the mid-elevation peak in Himalayan plant species richness

Martin Macek, Miroslav Dvorsky, Adam Klimes, Jan Wild, Jiri Dolezal & Martin Kopecký
The midpoint attractor models (MPA) of species richness integrate a unimodal environmental favourability gradient and neutral effects forced by geometric constraints and thus extend ecologically neutral mid-domain model. However, both alternative MPA algorithms assume that underlying environmental favourability peaks within the modeling domain. Here, we used elevational distribution data for 1054 plant species occurring in NW Himalaya to explore species richness gradients and MPA performance in species groups defined by biogeography, taxonomy and life form....

Multidimensional trophic niche revealed by complementary approaches: gut content, digestive enzymes, fatty acids and stable isotopes in Collembola

Anton Potapov, Melanie Pollierer, Sandrine Salmon, Vladimír Šustr & Ting-Wen Chen
Trophic niche differentiation may explain coexistence and shape functional roles of species. In complex natural food webs, however, trophic niche parameters depicted by single and isolated methods may simplify the multidimensional nature of consumer trophic niches, which includes feeding processes such as food choice, ingestion, digestion, assimilation and retention. Here we explore the correlation and complementarity of trophic niche parameters tackled by four complementary methodological approaches, i.e., visual gut content-, digestive enzyme-, fatty acid- and...

Data from: Re-examination of species limits in Aspergillus section Flavipedes using advanced species delimitation methods and description of four new species

František Sklenář, Željko Jurjević, Jos Houbraken, Miroslav Kolařík, Maiken Cavling Arendrup, Karin Meinike Jørgensen, Joao Paulo Zen Siqueira, Josepa Gené, Takashi Yaguchi, Chibundu Ngozi Ezekiel, Cristina Silva Pereira & Vít Hubka
Since the last revision in 2015, the taxonomy of section Flavipedes evolved rapidly along with the availability of new species delimitation techniques. This study aims to re-evaluate the species boundaries of section Flavipedes members using modern delimitation methods applied to an extended set of strains (n=90) collected from various environments. The analysis used DNA sequences of three house-keeping genes (benA, CaM, RPB2) and consisted of two steps: application of several single-locus (GMYC, bGMYC, PTP, bPTP)...

Morphological and behavioural differences facilitate tropical butterfly persistence in variable environments

Cheng Wenda, Shuang Xing, Akihiro Nakamura & Timothy C. Bonebrake
1. The thermal biology of ectotherms largely determines their abundance and distributions. In general, tropical species inhabiting warm and stable thermal environments tend to have low tolerance to cold and variable environments, which may restrict their expansion into temperate climates. However, the distribution of some tropical species does extend into cooler areas such as tropical borders and high elevation tropical mountains. Behavioural and morphological differences may therefore play important roles in facilitating tropical species to...

Data from: Are belowground clonal traits good predictors of ecosystem functioning in temperate grasslands?

Jitka Klimesova, Ondrej Mudrak, Jana Martinkova, Ales Lisner, Jan Leps, Arinawa Filartiga & Gianluigi Ottaviani
Dataset contains data on biomass distribution, soil characteristics and trait data for 52 temperate grasslands. Data are presented at community level. Biomass distribution (aboveground biomass, rhizome biomass, and root biomass) and soil chemistry data are original. The trait data are from existing databases and are presented as averages for a community (not weighted by species abundance).

Data from: Temporal turnover of the soil microbiome composition is guild-specific

Tijana Martinovic, Iñaki Odriozola, Tereza Mašínová, Barbara Bahnmann, Petr Kohout, Petr Sedlák, Kristina Merunková, Tomáš Větrovský, Michal Tomšovský, Otso Ovaskainen & Petr Baldrian
Although spatial and temporal variation are both important components structuring microbial communities, the exact quantification of temporal turnover rates of fungi and bacteria has not been performed to date. In this study, we utilized repeated resampling of bacterial and fungal communities at specific locations across multiple years to describe their patterns and rates of temporal turnover. Our results show that microbial communities undergo temporal change at a rate of 0.010-0.025 per year (in units of...

Complex reticulate evolution of the speckled brush-furred rats (Lophuromys) in the Ethiopian centre of endemism

Valeria Komarova, Danila Kostin, Josef Bryja, Ondřej Mikula, Anna Bryjová, Dagmar Čížková, Radim Šumbera, Yonas Meheretu & Leonid Lavrenchenko
The Ethiopian highlands represent a remarkable biodiversity “hotspot” with a very high number of endemic species, even among vertebrates. Ethiopian representatives of a species complex of speckled brush-furred rats (Lophuromys flavopunctatus sensu lato) inhabit highland habitats ranging from low-elevation forests to Afroalpine grasslands. These may serve as a suitable model for understanding evolutionary processes leading to high genetic and ecological diversity in montane biodiversity hot-spots. Here, we analyze the most comprehensive genetic dataset of this...

Cercarial behaviour alters the consumer functional response of three-spined sticklebacks

Ana Born-Torrijos, Rachel Paterson, Gabrielle Van Beest, Tereza Vyhlídalová, Eirik Haugstvedt Henriksen, Rune Knudsen, Roar Kristoffersen, Per-Arne Amundsen & Miroslava Soldánová
1. Free-living parasite life stages may contribute substantially to ecosystem biomass and thus represent a significant source of energy flow when consumed by non-host organisms. However, ambient temperature and the predator’s own infection status may modulate consumption rates towards parasite prey. 2. We investigated the combined effects of temperature and predator infection status on the consumer functional response of three-spined sticklebacks towards the free-living cercariae stages of two common freshwater trematode parasites (Plagiorchis, Trichobilharzia). 3....

Weak coordination between leaf drought tolerance and proxy traits in herbaceous plants

Maria Májeková, Tomáš Hájek, Agnes J. Albert, Francesco De Bello, Jiří Doležal, Lars Götzenberger, Stepan Janeček, Jan Lepš, Pierre Liancourt & Ondrej Mudrák
Increased drought is predicted to have a major impact on plant performance under environmental change. Yet leaf hydraulic traits directly related to drought tolerance, such as leaf turgor loss point (πtlp), are underrepresented in trait-based studies and have been largely overlooked within the main frameworks evaluating trait–trait coordination and trade-offs: the leaf economics spectrum and the global spectrum of plant form and function. Using 122 herbaceous species from the Central European temperate grasslands, we investigated...

Macroevolutionary foundations of a recently-evolved innate immune defense (data)

Milan Vrtílek & Daniel I. Bolnick
Antagonistic interactions between hosts and parasites may drive the evolution of novel host defenses, or new parasite strategies. Host immunity is therefore one of the fastest evolving traits. But where do the novel immune traits come from? Here, we test for phylogenetic conservation in a rapidly evolving immune trait – peritoneal fibrosis. Peritoneal fibrosis is a costly defense against a specialist tapeworm, Schistocephalus solidus (Cestoda), expressed in some freshwater populations of threespine stickleback fish (Gasterosteus...

Ontogeny, phylogeny, and mechanisms of adaptive changes in evaporative water loss in geckos

Zuzana Starostova, Martin Hluben, Lukas Kratochvil & Lumir Gvozdik
Body-size dependence of metabolic rate, body surface and scale morphology complicate disentangling the contribution of these characteristics to adaptive changes in total evaporative water loss (TEWL) of reptiles. To separate adaptive changes from size-related dependence, we compared intra- and interspecific scaling of several candidate traits in eyelid geckos (Eublepharidae), a group exhibiting large variation in body size and TEWL. The intraspecific allometry of TEWL of an eublepharid species fits the geometric surface-mass relationship. However, evolutionary...

Group intrusions by a brood parasitic fish are competitive not cooperative

Martin Reichard, Radim Blazek & Matej Polacik
Brood parasites delegate all parental duties to unrelated hosts. Hosts resistance against brood parasitism is most effective during egg laying and is best countered by surreptitious oviposition. This may be aided through distraction of host attention by the male partner or a larger cooperative group. Cuckoo catfish (Synodontis multipunctatus) parasitize the broods of mouthbrooding cichlids, which collect their eggs immediately after oviposition. Cuckoo catfish must time their intrusion precisely, as the temporal window for parasitism...

Characteristics of the naturalized flora of Southern Africa largely reflect the non-random introduction of alien species for cultivation

Ali Omer, Trevor Fristoe, Qiang Yang, Noëlie Maurel, Patrick Weigelt, Holger Kreft, Jonas Bleilevens, Wayne Dawson, Franz Essl, Jan Pergl, Mark Van Kleunen & Petr Pyšek
This dataset contains data on the cultivated alien and native flora of Southern Africa associated with data on geographic origins, growth form, functional traits, and naturalization status extracted from different data sources described in Omer, A. et al. 2021. Characteristics of the naturalized flora of Southern Africa largely reflect the non-random introduction of alien species for cultivation– Ecography. doi: 10.1111/ecog.05669. It is frequently overlooked, however, that patterns in origin, phylogeny, and traits of naturalized alien...
