Seabed mapping data from remote sensing and groundtruth samples taken at East of Haig Fras Marine Conservation Zone from 2012 to 2015

As described in the manuscript entitled "Limitations of predicting substrate classes on a sedimentary complex but morphologically simple seabed" remotely sensed variables and ground truth samples were distributed as part of a seabed mapping exercise. This holding contains the four raster layers provided to all participants for the East of Haig Fras MCZ and the groundtruth samples. These four rasters are: Multibeam echosounder bathymetry, multibeam echosounder backscatter, modelled maximum current velocity at the seabed and...

Data from: A new small, mesorostrine inioid (Cetacea, Odontoceti, Delphinida) from four late Miocene localities of the Pisco Basin, Peru

Olivier Lambert, Alberto Collareta, Aldo Benites-Palomino, Claudio Di Celma, Christian De Muizon, Mario Urbina & Giovanni Bianucci
The moderately rich past diversity of the superfamily Inioidea (Cetacea, Odontoceti) in both the Atlantic and Pacific oceans contrasts with the present survival of a single genus (Inia, Amazon river dolphin, family Iniidae) in freshwater deposits of South America and of a single species (Pontoporia blainvillei, Franciscana, family Pontoporiidae) along the eastern coast of that continent. However, part of the late Miocene to Pliocene inioid fossil record is made of relatively fragmentarily known species, for...

Data from: Evolutionary history of a dispersal-associated locus across sympatric and allopatric divergent populations of a wing-polymorphic beetle across Atlantic Europe

Steven M. Van Belleghem, Dick Roelofs & Frederik Hendrickx
Studying the evolutionary history of trait divergence, in particular those related to dispersal capacity, is of major interest for the process of local adaptation and metapopulation dynamics. Here, we reconstruct the evolution of different alleles at the nuclear encoded mitochondrial NADP+-dependent isocitrate dehydrogenase (mtIdh) locus of the ground beetle Pogonus chalceus that are differentially and repeatedly selected in short- and long-winged populations in response to different hydrological regimes at both allopatric and sympatric scales along...

Horton, Stephanie Wynne-Jones, Jeffrey Fleisher, Chantal Radimilahy, Henry Wright … & Mark Horton
Human-mediated biological exchange has had global social and ecological impacts. In sub-Saharan Africa, several domestic and commensal animals were introduced from Asia in the pre-modern period; however, the timing and nature of these introductions remain contentious. One model supports introduction to the eastern African coast after the mid-first millennium CE, while another posits introduction dating back to 3000 BCE. These distinct scenarios have implications for understanding the emergence of long-distance maritime connectivity, and the ecological...

Yves Basset, Lukas Cizek, Philippe Cuénoud, Raphael K. Didham, François Guilhaumon, Olivier Missa, Vojtech Novotny, Frode Ødegaard, Tomas Roslin, Jürgen Schmidl, Alexey K. Tishechkin, Neville N. Winchester, David W. Roubik, Henri-Pierre Aberlenc, Johannes Bail, Héctor Barrios, Jon 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 … & Maurice Leponce
Most eukaryotic organisms are arthropods. Yet, their diversity in rich terrestrial ecosystems is still unknown. Here we produce tangible estimates of the total species richness of arthropods in a tropical rainforest. Using a comprehensive range of structured protocols, we sampled the phylogenetic breadth of arthropod taxa from the soil to the forest canopy in the San Lorenzo forest, Panama. We collected 6,144 arthropod species from 0.48 ha and extrapolated total species richness to larger areas...

Data from: Selection for costly sexual traits results in a vacant mating niche and male dimorphism

Frederik Hendrickx, Bram Vanthournout & Michael Taborsky
The expected strong directional selection for traits that increase a male's mating ability conflicts with the frequent observation that within species, males may show extreme variation in sexual traits. These male reproductive polymorphisms are usually attributed to direct male-male competition. It is currently unclear, however, how directional selection for sexually selected traits may convert into disruptive selection, and if female preference for elaborate traits may be an alternative mechanism driving the evolution of male polymorphism....

Data from: Cross-taxa generalities in the relationship between population abundance and ambient temperatures

Diana E. Bowler, Peter Haase, Christian Hof, Ingrid Kröncke, Léon Baert, Wouter Dekoninck, Sami Domisch, Frederik Hendrickx, Thomas Hickler, Hermann Neumann, Robert B. O'Hara, Anne F. Sell, Moritz Sonnewald, Stefan Stoll, Michael Türkay, Roel Van Klink, Oliver Schweiger, Rikjan Vermeulen & Katrin Boehning-Gaese
Identifying patterns in the effects of temperature on species' population abundances could help develop a general framework for predicting the consequences of climate change across different communities and realms. We used long-term population time series data from terrestrial, freshwater, and marine species communities within central Europe to compare the effects of temperature on abundance across a broad range of taxonomic groups. We asked whether there was an average relationship between temperatures in different seasons and...

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: On the origin of the Norwegian lemming

Vendela K. Lagerholm, Edson Sandoval-Castellanos, Dorothee Ehrich, Natalia I. Abramson, Adam Nadachowski, Daniela C. Kalthoff, Mietje Germonpré, Anders Angerbjörn, John R. Stewart & Love Dalén
The Pleistocene glacial cycles resulted in significant changes in species distributions, and it has been discussed whether this caused increased rates of population divergence and speciation. One species that is likely to have evolved during the Pleistocene is the Norwegian lemming (Lemmus lemmus). However, the origin of this species, both in terms of when and from what ancestral taxon it evolved, has been difficult to ascertain. Here, we use ancient DNA recovered from lemming remains...

Data from: Regional environmental pressure influences population differentiation in turbot (Scophthalmus maximus)

S. G. Vandamme, G. E. Maes, J. A. M. Raeymaekers, K. Cottenie, A. K. Imsland, B. Hellemans, G. Lacroix, E. Mac Aoidh, J. T. Martinsohn, P. Martínez, J. Robbens, R. Vilas & F. A. M. Volckaert
Unravelling the factors shaping the genetic structure of mobile marine species is challenging due to the high potential for gene flow. However, genetic inference can be greatly enhanced by increasing the genomic, geographic or environmental resolution of population genetic studies. Here we investigated the population structure of turbot (Scophthalmus maximus) by screening 17 random and gene-linked markers in 999 individuals at 290 geographical locations throughout the Northeast Atlantic Ocean. A seascape genetics approach with the...

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: Parasite escape through trophic specialization in a species flock

Pascal I. Hablützel, Maarten P.M. Vanhove, Pablo Deschepper, Arnout F. Grégoir, Anna K. Roose, Filip A.M. Volckaert & Joost A.M. Raeymaekers
Adaptive radiation occurs when species diversify rapidly to occupy an array of ecological niches. Since opportunities for parasite infection and transmission may greatly vary among these niches, adaptive radiation is expected to be associated with a turnover of the parasite community. As major agents of natural and sexual selection, parasites may play a central role in host diversification. The study of parasite turnover may thus be of general relevance and could significantly improve our understanding...

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: Resource use and food preferences in understorey ant communities along a complete elevational gradient in Papua New Guinea

Jerome Orivel, Petr Klimes, Vojtech Novotny & Maurice Leponce
Elevational gradients provide an interesting opportunity for studying the effect of climatic drivers over short distances on the various facets of biodiversity. It is globally assumed that the decrease in species richness with increasing elevation follows mainly the decrease in ecosystem productivity, but studies on functional diversity still remain limited. Here, we investigated how resource use and food preferences by both individual ant species and communities foraging in the understorey vary with elevation along a...

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...

Species distribution, hybridization and connectivity in the genus Chionodraco: unveiling unknown icefish diversity in Antarctica

Luca Schiavon, Valérie Dulière, Mario La Mesa, Ilaria Marino, Giuditta Codogno, Elisa Boscari, Emilio Riginella, Alessandra Battistotti, Magnus Lucassen, Lorenzo Zane & Chiara Papetti
Aim The species of the genus Chionodraco (Notothenioidei) are the most abundant icefish on the continental shelf of the Weddell Sea. While previous studies indicated that only Chionodraco hamatus and Chionodraco myersi inhabit the Weddell Sea, the third Chionodraco species, Chionodraco rastrospinosus, was recently sampled in the area. Since C. rastrospinosus is supposed to be found only at the Antarctic Peninsula and Scotia Arc, this study aimed at confirming the species classification of C. rastrospinosus...

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: Cryptic diversity and gene flow among three African agricultural pests: Ceratitis rosa, Ceratitis fasciventris and Ceratitis anonae (Diptera, Tephritidae)

Massimiliano Virgilio, Helene Delatte, Serge Quilici, Thierry Backeljau & Marc De Meyer
The ‘Ceratitis FAR complex’ is a species complex of African fruit flies (Diptera, Tephritidae) including the major agricultural pest Ceratitis rosa and the morphologically similar Ceratitis fasciventris and Ceratitis anonae. To resolve their intra- and interspecific genetic relationships and to estimate gene flow within this complex, we surveyed allelic variation at 16 microsatellite loci in 27 African populations of the three morphospecies. Interpopulation genetic distances and individual Bayesian assignments distinguished five genotypic clusters: two involving...

Data from: Adaptation of a polyphagous herbivore to a novel host plant extensively shapes the transcriptome of herbivore and host

Nicky Wybouw, Vladimir Zhurov, Catherine Martel, Kristie A. Bruinsma, Frederik Hendrickx, Vojislava Grbić & Thomas Van Leeuwen
Generalist arthropod herbivores rapidly adapt to a broad range of host plants. However, the extent of transcriptional reprogramming in the herbivore and its hosts associated with adaptation remains poorly understood. Using the spider mite Tetranychus urticae and tomato as models with available genomic resources, we investigated the reciprocal genomewide transcriptional changes in both spider mite and tomato as a consequence of mite's adaptation to tomato. We transferred a genetically diverse mite population from bean to...

Data from: Arthropod distribution in a tropical rainforest: tackling a four dimensional puzzle

Yves Basset, Lukas Cizek, Philippe Cuénoud, Raphael K. Didham, Vojtech Novotny, Frode Ødegaard, Tomas Roslin, Alexey K. Tishechkin, Jürgen Schmidl, Neville N. Winchester, David W. 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...

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...

Data from: Ancient and modern DNA reveal dynamics of domestication and cross-continental dispersal of the dromedary

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...

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...
