Data from: New fossil Hyaenodonta (Mammalia, Placentalia) from the Ypresian and Lutetian of France and the evolution of the Proviverrinae in southern Europe

Floréal Solé, Jocelyn Falconnet & Dominique Vidalenc
The proviverrines from the Ypresian (MP7–MP10) and Lutetian (MP11–MP14) are represented mainly by species recorded in the northern and central parts of Europe (Paris Basin, Belgian Basin, Germany, Switzerland). Here, we describe fossils from southern France: Saint-Papoul (MP8 + 9; Aude) and Aigues-Vives 2 (?MP13; Aude). One dentary with secant molars from Saint-Papoul represents a new genus and species, Preregidens langebadrae. This taxon is possibly present in Avenay (France), the MP8 + 9 reference locality....

Data from: The cranium of Proviverra typica (Mammalia, Hyaenodonta) and its impact on hyaenodont phylogeny and endocranial evolution

Morgane Dubied, Floréal Solé & Bastien Mennecart
We describe the first endocast reconstruction of a hyaenodont mammal based on X‐ray microtomography. The endocast belongs to the type material of the European hyaenodont Proviverra typica. We performed phylogenetic analysis to contextualize the evolution of endocranial size and complexity in Hyaenodonta. We added several European hyaenodonts and modified several codings of the most recent character–taxon matrix established to question the relationships within Hyaenodonta. Including these new species in a phylogenetic analysis reveals a new...

Data from: Type Maastrichtian gastropod faunas evidencing rapid ecosystem recovery following the Cretaceous-Palaeogene boundary

Johan Vellekoop, Kris Van Tilborgh, Paul Van Knippenberg, John Jagt, Peter Stassen, Stijn Goolaerts & Robert Speijer
The study of the global mass extinction event at the Cretaceous–Palaeogene (K/Pg) boundary can aid in understanding patterns of selective extinction and survival, and dynamics of ecosystem recovery. Outcrops in the Maastrichtian type area (southeast Netherlands, northeast Belgium) comprise an exceptionally expanded K/Pg boundary succession that offers a unique opportunity to study marine ecosystem recovery within the first thousands of years following the mass extinction event. A quantitative analyses was performed on systematically sampled macrofossils...

Data from: DNA barcoding fishes from the Congo and the Lower Guinean provinces: assembling a reference library for poorly inventoried fauna

Gontran Sonet, Jos Snoeks, Zoltan T. Nagy, Emmanuel Vreven, Gert Boden, Floris C. Breman, Eva Decru, Mark Hanssens, Armel Ibala Zamba, Kurt Jordaens, Victor Mamonekene, Tobias Musschoot, Jeroen Van Houdt, Maarten Van Steenberge, Soleil Lunkayilakio Wamuini & Erik Verheyen
The Congolese and Lower Guinean ichthyological provinces are understudied hotspots of the global fish diversity. Here, we barcoded 741 specimens from the Lower and Middle Congo River and from three major drainage basins of the Lower Guinean ichthyological province, Kouilou-Niari, Nyanga and Ogowe. We identified 195 morphospecies belonging to 82 genera and 25 families. Most morphospecies (92.8%) corresponded to distinct clusters of DNA barcodes. Of the four morphospecies present in both neighbouring ichthyological provinces, only...

Impacts of beekeeping on wild bee diversity and pollination networks in the Aegean Archipelago

Amparo Lázaro, Andreas Mueller, Andreas Ebmer, Holger Dathe, Erwin Scheuchl, Maximilian Schwarz, Stephan Risch, Alain Pauly, Jelle Devalez, Thomas Tscheulin, Carmelo Gómez-Martínez, Evangelos Papas, John Pickering, Nickolas Waser & Theodora Petanidou
Maintaining the diversity of wild bees is a priority for preserving ecosystem function and promoting stability and productivity of agroecosystems. However, wild bee communities face many threats and beekeeping could be one of them, because honey bees may have a strong potential to outcompete wild pollinators when placed at high densities. Yet, we still know little about how beekeeping intensity affects wild bee diversity and their pollinator interactions. Here, we explore how honey bee density...

Data from: Evolution at two time frames: polymorphisms from an ancient singular divergence event fuel contemporary parallel evolution

Steven M. Van Belleghem, Carl Vangestel, Katrien De Wolf, Zoë De Corte, Markus Möst, Pasi Rastas, Luc De Meester & Frederik Hendrickx
When environments change, populations may adapt surprisingly fast, repeatedly and even at microgeographic scales. There is increasing evidence that such cases of rapid parallel evolution are fueled by standing genetic variation, but the source of this genetic variation remains poorly understood. In the saltmarsh beetle Pogonus chalceus, short-winged ‘tidal’ and long-winged ‘seasonal’ ecotypes have diverged in response to contrasting hydrological regimes and can be repeatedly found along the Atlantic European coast. By analyzing genomic variation...

Data from: Persistent inter- and intraspecific gene exchange within a parallel radiation of caterpillar hunter beetles (Calosoma sp.) from the Galápagos

Frederik Hendrickx, Viki Vandomme, Carl Vangestel, Thierry Backeljau, Wouter Dekoninck & Steven M. Van Belleghem
When environmental gradients are repeated on different islands within an archipelago, similar selection pressures may act within each island, resulting in the repeated occurrence of ecologically similar species on each island. The evolution of ecotypes within such radiations may either result from dispersal, that is each ecotype evolved once and dispersed to different islands where it colonized its habitat, or through repeated and parallel speciation within each island. However, it remains poorly understood how gene...

Data from: An enigmatic new ungulate-like mammal from the early Eocene of India

Shawn Zack, Kenneth Rose, Luke Holbrook, Kishor Kumar, Rajendra Rana & Thierry Smith
We report on a new genus and species of herbivorous mammal, Pahelia mysteriosa, from the early Eocene Cambay Shale Formation, Tadkeshwar Lignite Mine, Gujarat, India. The new taxon, approximately the size of a small phenacodontid (e.g., Ectocion parvus), is represented by three mandibular fragments, the most complete of which documents nearly the entire symphysis and mandibular body plus P3-M3. Pahelia has incipiently selenolophodont molars with strong exodaenodonty, absent paraconids, weak but distinct entolophids, and prominent...

Data from: Distribution of the invasive Caprella mutica Schurin, 1935 and native Caprella linearis (Linnaeus, 1767) on artificial hard substrates in the North Sea: separation by habitat

Joop W.P. Coolen, Wouter Lengkeek, Steven Degraer, Francis Kerckhof, Roger J. Kirkwood, Han J. Lindeboom & Han Lindeboom
Studying offshore natural and artificial hard substrates in the southern North Sea (51ºN–57ºN/1ºW–9ºE), the invasive introduced Japanese skeleton shrimp Caprella mutica Schurin, 1935 was found to co-exist with the native Caprella linearis (Linnaeus, 1767) only on near-shore locations that had an intertidal zone (e.g., wind farm foundations). In contrast, on far offshore and strictly subtidal locations, such as shipwrecks and rocky reefs, only C. linearis was found. Based on these exploratory observations, we hypothesised that...

Data from: Genetics, morphology, advertisement calls, and historical records distinguish six new polyploid species of African clawed frog (Xenopus, Pipidae) from West and Central Africa

Ben J. Evans, Timothy F. Carter, Eli Greenbaum, Václav Gvoždík, Darcy B. Kelley, Patrick J. McLaughlin, Olivier S. G. Pauwels, Daniel M. Portik, Edward L. Stanley, Richard C. Tinsley, Martha L. Tobias & David C. Blackburn
African clawed frogs, genus Xenopus, are extraordinary among vertebrates in the diversity of their polyploid species and the high number of independent polyploidization events that occurred during their diversification. Here we update current understanding of the evolutionary history of this group and describe six new species from west and central sub-Saharan Africa, including four tetraploids and two dodecaploids. We provide information on molecular variation, morphology, karyotypes, vocalizations, and estimated geographic ranges, which support the distinctiveness...

Data from: Assessing the impact of beach nourishment on the intertidal food web through the development of a mechanistic-envelope model

Sarah Vanden Eede, Joke Van Tomme, Charlotte De Busschere, Martijn Vandegehuchte, Koen Sabbe, Eric W. M. Stienen, Steven Degraer, Magda Vincx, Dries Bonte, Martijn L. Vandegehuchte & Eric W.M. Stienen
Beach nourishment, the placement of sand onto a sediment-starved stretch of coast, is widely applied as a soft coastal protection measure because of its reduced ecological impact relative to hard coastal protection. In order to predict effects on the intertidal sandy beach ecosystem, we developed a simulation model that integrates species envelope-based projections for the dominant macrobenthos species and mechanistic food web modules for higher trophic levels. Species envelopes were estimated by using Bayesian inference...

Prendergast, Nicole Boivin, Arturo Morales-Muñiz, Adrian Bălăşescu, Cornelia Becker, Norbert Benecke, Adina Boroneant, Hijlke Buitenhuis, Jwana Chahoud, Alison Crowther, Laura Llorente, Nina Manaseryan, Hervé Monchot, Vedat Onart, Marta Osypińska, Olivier Putelat, Eréndira M. Quintana Morales, Jacqueline Studer … & Eva-Maria Geigl
The cat has long been important to human societies as a pest-control agent, object of symbolic value and companion animal, but little is known about its domestication process and early anthropogenic dispersal. Here we show, using ancient DNA analysis of geographically and temporally widespread archaeological cat remains, that both the Near Eastern and Egyptian populations of Felis silvestris lybica contributed to the gene pool of the domestic cat at different historical times. While the cat’s...

Data from: Trophic interactions in an ant nest microcosm: a combined experimental and stable isotope (δ13C/δ15N) approach

Thomas Parmentier, Steven Bouillon, Wouter Dekoninck & Tom Wenseleers
Living in close association with other organisms has proven to be a widespread and successful strategy in nature. Some communities are completely driven by symbiotic associations and therefore, intimate relationships among the partners can be expected. Here, we analyzed in-depth the food web of a particularly rich community of arthropods found in strict association with European red wood ants (Formica rufa group). We studied the trophic links between different ant-associated myrmecophiles and food sources associated...

Summary of the microsatellite genotyping analysis of 280 C. gariepinus samples originating from eight locations in the Congo basin using five microsatellite markers

Aim The formation history of Africa’s current river basins remains largely unknown. In order to date changes in landscape and climate, we studied the biogeography of the African freshwater fish with the largest natural distribution. We also validated biogeographic units. Location Continental Africa. Taxon Clarias gariepinus sl. Methods We investigated mitochondrial cytb sequences of 443 individuals from 97 localities, using a haplotype network and a genetic landscape analysis. We inferred a dated phylogeny using maximum...

Discovery-defense strategy as a mechanism of social foraging of ants in tropical rainforest canopies

Wesley Dáttilo, Reuber Antoniazzi, Flavio Camarota & Maurice Leponce
Many hypotheses have been proposed to explain the coexistence of ants sharing similar food resources, including ecological trade-offs, however, these hypotheses have mostly been tested in ground-dwelling ant communities. For instance, the discovery-dominance trade-off hypothesis states that species with overlapping food resources differ in their ability to find and dominate resources. However, ant species may use different strategies to share food resources, including discovery-defense, in which the first species to arrive at a food resource...

Data from: Using structured eradication feasibility assessment to prioritise the management of new and emerging invasive alien species in Europe

Olaf Booy, Peter A. Robertson, Niall Moore, Jess Ward, Helen E. Roy, Tim Adriaens, Richard Shaw, Johan Van Valkenburg, Gabe Wyn, Sandro Bertolino, Olivier Blight, Etienne Branquart, Giuseppe Brundu, Joe Caffrey, Dario Capizzi, Jim Casaer, Olivier De Clerck, Neil Coughlan, Eithne Davis, Jaimie Dick, Franz Essl, Guillaume Fried, Piero Genovesi, Pablo González-Moreno, Frank Hysentruyt … & Aileen C. Mill
Prioritising the management of invasive alien species (IAS) is of global importance and within Europe integral to the EU IAS regulation. To prioritise management effectively the risks posed by IAS need to be assessed, but so too does the feasibility of their management. While risk of IAS to the EU has been assessed, the feasibility of management has not. We assessed the feasibility of eradicating 60 new (not yet established) and 35 emerging (established with...

Data from: Male spiders control offspring sex ratio through greater production of female-determining sperm

Bram Vanthournout, Mette Marie Busck, Jesper Bechsgaard, Frederik Hendrickx, Andreas Schramm & Trine Bilde
Sex allocation theory predicts that when sons and daughters have different reproductive values, parents should adjust offspring sex ratio towards the sex with the higher fitness return. Haplo-diploid species directly control offspring sex ratio, but species with chromosomal sex determination (CSD) were presumed to be constrained by Mendelian segregation. There is now increasing evidence that CSD species can adjust sex ratio strategically, but the underlying mechanism is not well understood. One hypothesis states that adaptive...

Data from: A molecular phylogeny and revised higher-level classification for the leaf-mining moth family Gracillariidae and its implications for larval host-use evolution

Akito Y. Kawahara, David Plotkin, Issei Ohshima, Carlos Lopez-Vaamonde, Peter R. Houlihan, Jesse W. Breinholt, Atsushi Kawakita, Lei Xiao, Jerome C. Regier, Donald R. Davis, Tosio Kumata, Jay-Cheon Sohn, Jurate De Prins, Charles Mitter & JAE-CHEON SOHN
Gracillariidae are one of the most diverse families of internally feeding insects, and many species are economically important. Study of this family has been hampered by lack of a robust and comprehensive phylogeny. In the present paper, we sequenced up to 22 genes in 96 gracillariid species, representing all previously recognized subfamilies and genus groups, plus 20 outgroups representing other families and superfamilies. Following objective identification and removal of two rogue taxa, two datasets were...

Data from: Behavioral adaptations imply a direct link between ecological specialization and reproductive isolation in a sympatrically diverging ground beetle

Steven M. Van Belleghem, Katrien De Wolf & Frederik Hendrickx
Adaptation to a previously unoccupied niche within a single population is one of the most contentious topics in evolutionary biology as it assumes the simultaneous evolution of ecologically selected and preference traits. Here, we demonstrate behavioral adaptation to contrasting hydrological regimes in a sympatric mosaic of Pogonus chalceus beetle populations, and argue that this adaptation may result in nonrandom gene flow. When exposed to experimental inundations, individuals from tidal marshes, which are naturally subjected to...

Faisal Almathen, Pauline Charruau, Elmira Mohandesan, Joram M. Mwacharo, Pablo Orozco-TerWengel, Daniel Pitt, Abdussamad M. Abdussamad, Margarethe Uerpmann, Hans-Peter Uerpmann, Bea De Cupere, Peter Magee, Majed A. Alnaqeeb, Bashir Salim, Abdul Raziq, Tadelle Dessie, Omer M. Abdelhadi, Mohammad H. Banabazi, Marzook Al-Eknah, Chris Walzer, Bernard Faye, Michael Hofreiter, Joris Peters, Olivier Hanotte & Pamela A. Burger
Dromedaries have been fundamental to the development of human societies in arid landscapes and for long-distance trade across hostile hot terrains for 3,000 y. Today they continue to be an important livestock resource in marginal agro-ecological zones. However, the history of dromedary domestication and the influence of ancient trading networks on their genetic structure have remained elusive. We combined ancient DNA sequences of wild and early-domesticated dromedary samples from arid regions with nuclear microsatellite and...

Precision mapping of snail habitat provides a powerful indicator of human schistosomiasis transmission

Chelsea Wood, Susanne Sokolow, Isabel Jones, Andrew Chamberlin, Kevin Lafferty, Armand Kuris, Merlijn Jocque, Skylar Hopkins, Grant Adams, Julia Buck, Andrea Lund, Ana Garcia-Vedrenne, Evan Fiorenza, Jason Rohr, Fiona Allan, Bonnie Webster, Muriel Rabone, Joanne Webster, Lydie Bandagny, Raphael Ndione, Simon Senghor, Anne-Marie Schacht, Nicolas Jouanard, Gilles Riveau & Giulio De Leo
Recently, the World Health Organization recognized that efforts to interrupt schistosomiasis transmission through mass drug administration have been ineffective in some regions; one of their new recommended strategies for global schistosomiasis control emphasizes targeting the freshwater snails that transmit schistosome parasites. We sought to identify robust indicators that would enable precision targeting of these snails. At the site of the world’s largest recorded schistosomiasis epidemic—the Lower Senegal River Basin in Senegal—intensive sampling revealed positive relationships...

Roubik, Henri-Pierre Aberlenc, Johannes Bail, Héctor Barrios, Jonathan R. Bridle, Gabriela Castaño-Meneses, Bruno Corbara, Gianfranco Curletti, Wesley Duarte Da Rocha, Domir De Bakker, Jacques H.C. Delabie, Alain Dejean, Laura L. Fagan, Andreas Floren, Roger L. Kitching … & Jacques H. C. Delabie
Quantifying the spatio-temporal distribution of arthropods in tropical rainforests represents a first step towards scrutinizing the global distribution of biodiversity on Earth. To date most studies have focused on narrow taxonomic groups or lack a design that allows partitioning of the components of diversity. Here, we consider an exceptionally large dataset (113,952 individuals representing 5,858 species), obtained from the San Lorenzo forest in Panama, where the phylogenetic breadth of arthropod taxa was surveyed using 14...

Data from: Testing the potential of DNA barcoding in vertebrate radiations: the case of the littoral cichlids (Pisces, Perciformes, Cichlidae) from Lake Tanganyika

Floris C. Breman, Sara Loix, Kurt Jordaens, Jos Snoeks & Maarten Van Steenberge
We obtained 398 cytochrome c oxidase subunit I barcodes of 96 morphospecies of Lake Tanganyika (LT) cichlids from the littoral zone. The potential of DNA barcoding in these fishes was tested using both species identification and species delineation methods. The best match (BM) and best close match (BCM) methods were used to evaluate the overall identification success. For this, three libraries were analysed in which the specimens were categorized into Operational Taxonomic Units (OTU) in...
