Data from: The way wear goes – phytolith-based wear on the dentine-enamel system in guinea pigs (Cavia porcellus)

Louise F. Martin, Daniela Winkler, Thomas Tütken, Codron Daryl, Annelies De Cuyper, Jean-Michel Hatt & Marcus Clauss
The effect of phytoliths on tooth wear and function has been contested in studies of animal plant interactions. For herbivores whose occlusal chewing surface consists of enamel ridges in dentine tissue, the phytoliths might first erode the softer dentine, exposing the enamel ridges to different occlusal forces and thus leading to enamel wear. To test this hypothesis, we fed guinea pigs (Cavia porcellus; n=36 in 6 groups) for three weeks exclusively on dry or fresh...

The hornwort genome and early land plant evolution

Jian Zhang, Xin-Xing Fu, Rui-Qi Li, Xiang Zhao, Yang Liu, Ming-He Li, Arthur Zwaenepoel, Hong Ma, Bernard Goffinet, Yan-Long Guan, Jia-Yu Xue, Yi-Ying Liao, Qing-Feng Wang, Qing-Hua Wang, Jie-Yu Wang, Guo-Qiang Zhang, Zhi-Wen Wang, Yu Jia, Mei-Zhi Wang, Shan-Shan Dong, Jian-Fen Yang, Yuan-Nian Jiao, Ya-Long Guo, Hong-Zhi Kong, An-Ming Lu … & Zhi-Duan Chen
Hornworts, liverworts, and mosses are three early diverging clades of land plants, together composing the bryophytes. Here we report the draft genome sequence of the hornwort Anthoceros angustus. Phylogenomic inferences confirm the monophyly of bryophytes, with hornworts sister to liverworts and mosses. The simple morphology of hornworts correlates with low genetic redundancy in plant body plan while the basic transcriptional regulation toolkit for plant development has already been established in this early land plant lineage....

Signal evolution and morphological complexity in hummingbirds (Aves: Trochilidae)

Chad Eliason, Rafael Maia, Juan Parra & Matthew Shawkey
Understanding how animal signals are produced is critical for understanding their evolution because complexity and modularity in the underlying morphology can affect evolutionary patterns. Hummingbird feathers show some of the brightest and most iridescent colors in nature. These are produced by optically complex stacks of hollow, platelet-shaped organelles called melanosomes. Neither how these morphologies produce colors nor their evolution has been systematically studied. We first used nanoscale morphological measurements and optical modeling to identify the...

Liana communities exhibit different species composition, diversity and community structure across forest types in the Congo Basin

Francis Mumbanza M., Marijn Bauters, Elizabeth Kearsley, Pascal Boeckx, Constantin Lubini A. & Hans Verbeeck
Lianas are poorly characterized for central African forests. We quantify variation in liana composition, diversity and community structure in different forest types in the Yangambi Man and Biosphere Reserve, Democratic Republic of Congo. These attributes of liana assemblages were examined in 12 1-ha plots, randomly demarcated within regrowth forest, old-growth monodominant forest, old-growth mixed forest and old-growth edge forest. Using a combination of multivariate and univariate community analyses, we visualize the patterns of these liana...

Decane and brine injected into Estaillades carbonate - steady-state experiments

Catherine Spurin, Samuel Krevor, Martin Blunt & Tom Bultreys
This data is micro-CT images of the simultaneous injection of decane and brine into a porous carbonate rock (Estaillades). The images were acquired during steady-state, which was deduced from a plateau in the differential pressure across the sample. The experiments were conducted in the capillary dominated regime (the total flow rate was kept constant, with the fractional flow (fw) changed in sequence 0.85fw, 0.7fw, 0.5fw, 0.25fw, 0fw). The total flow rate was kept constant at...

Data from: Resource predictability drives inter-annual variation in migratory behaviour in a long-lived bird

Jan Baert, Eric Stienen, Frederick Verbruggen, Nico Van De Weghe, Luc Lens & Wendt Müller
There is a growing awareness that experience may play a major role in migratory decisions, especially in long-lived species. However, empirical support remains to date scarce. Here, we use multi-year GPS-tracking data on 28 adult Lesser Black-backed Gulls (Larus fuscus), a long-lived species for which migratory strategies typically consist of a series of long stopovers, to assess how experience affects interannual variation in stopover selection. We expect that food source reliability should play a pivotal...

Data from: Thermal differences between juveniles and adults increased over time in European forest trees

Maria Mercedes Caron, Florian Zellweger, Kris Verheyen, Lander Baeten, Radim Hédl, Bernhardt-Römermann Markus, Imre Berki, Jörg Brunet, Guillaume Decocq, Sandra Díaz, Thomas Dirnböck, Tomasz Durak, Thilo Heinken, Bogdan Jaroszewicz, Martin Kopecký, Jonathan Lenoir, Martin Macek, Malicki Marek, František Máliš, Thomas Nagel, Michael Perring, Petr Petřík, Kamila Reczyńska, Remigiusz Pielech, Wolfgang Schmidt … & Pieter De Frenne
Woody species’ requirements and environmental sensitivity change from seedlings to adults, a process referred to as ontogenetic shift. Such shifts can be increased by climate change. To assess the changes in the difference of temperature experienced by seedlings and adults in the context of climate change, it is essential to have reliable climatic data over long periods that capture the thermal conditions experienced by the individuals throughout their life cycle. Here we used a unique...

Data from: Freshwater ecological quality assessment of the gold mining Mashcon watershed, Cajamarca - Peru

Daniel Mercado-Garcia, Marco Sanchez Peña, Marie Anne Eurie Forio, Eveline Beeckman, Jana Van Butsel, Nilton Deza Arroyo, Karel De Schamphelaere, Guido Wyseure & Peter Goethals
These data were generated to investigate the aquatic community gradients across different types of anthropogenic impacts (reference, mining, rural and urban) and Andean environmental gradients (headwaters, midstream and downstream) in the Mashcon watershed. The macroinvertebrates' taxa abundance and abundance of traits modalities serve as biological values. The latter in combination with abiotic measurements of the freshwater habitats (i.e. physicochemical water quality and hydromorphology) constitute the ecological data. The values were obtained from river sediments (macroinvertebrates...

Interacting host modifier systems control Wolbachia-induced cytoplasmic incompatibility in a haplodiploid mite

Nicky Wybouw
Reproductive parasites such as Wolbachia spread within host populations by inducing cytoplasmic incompatibility (CI). CI occurs when parasite-modified sperm fertilizes uninfected eggs and is typified by great variation in strength across biological systems. In haplodiploid hosts, CI has different phenotypic outcomes depending on whether the fertilized eggs die or develop into males. Genetic conflict theories predict the evolution of host modulation of CI, which in turn influences the stability of reproductive parasitism. Yet, despite the...

Global potential invasion maps of traded birds under climate and land-cover change

Babak Naimi, César Capinha, Joana Ribeiro, Carsten Rahbek, Diederik Strubbe, Luís Reino & Miguel Araujo
Biological invasions rank among the top five threatening factors affecting biodiversity, but ongoing changes in climate and land cover might exacerbate risks. We used species distribution models for 609 traded bird species on the CITES list to examine the combined effects of projected climate change and land-cover change worldwide on the potential range expansion of bird species with commercial value as pets. The maps of potential invasion (may be inferred as the invasion risk) have...

Data from: Rapid genetic adaptation precedes the spread of an exotic plant species

Katrien Vandepitte, Tim De Meyer, Kenny Helsen, Kasper Van Acker, Isabel Roldán-Ruiz, Joachim Mergeay & Olivier Honnay
Human activities have increasingly introduced plant species far outside their native ranges under environmental conditions that can strongly differ from those originally met. Therefore, before spreading, and potentially causing ecological and economical damage, non native species may rapidly evolve. Evidence of genetically based adaptation during the process of becoming invasive is very scant however, which is due to the lack of knowledge regarding the historical genetic makeup of the introduced populations and the lack of...

Data from: Inferring the origin of populations introduced from a genetically structured native range by approximate Bayesian computation: case study of the invasive ladybird Harmonia axyridis

Eric Lombaert, Thomas Guillemaud, Cathleen E. Thomas, Lori J. Lawson Handley, Jiahui Li, Su Wang, Hong Pang, Irina Goryacheva, Ilya A. Zakharov, Emmanuelle Jousselin, Remy L. Poland, Alain Migeon, Joop Van Lenteren, Patrick De Clercq, Nick Berkvens, Walker Jones & Arnaud Estoup
Correct identification of the source population of an invasive species is a prerequisite for testing hypotheses concerning the factors responsible for biological invasions. The native area of invasive species may be large, poorly known and/or genetically structured. Because the actual source population may not have been sampled, studies based on molecular markers may generate incorrect conclusions about the origin of introduced populations. In this study, we characterized the genetic structure of the invasive ladybird Harmonia...

Data from: Microsatellite analysis of museum specimens reveals historical differences in genetic diversity between declining and more stable Bombus species

Kevin Maebe, Ivan Meeus, Maarten Ganne, Thibaut De Meulemeester, Koos Biesmeijer & Guy Smagghe
Worldwide most pollinators, e.g. bumblebees, are undergoing global declines. Loss of genetic diversity can play an essential role in these observed declines. In this paper, we investigated the level of genetic diversity of seven declining Bombus species and four more stable species with the use of microsatellite loci. Hereto we genotyped a unique collection of museum specimens. Specimens were collected between 1918 and 1926, in 6 provinces of the Netherlands which allowed us to make...
