Reciprocal selection between aphids, their protective endosymbionts, and the parasitoid wasps that prey upon them offers an opportunity to study the basis of their coevolution. We investigated adaptation to symbiont-conferred defense by rearing the parasitoid wasp Lysiphlebus fabarum on aphids (Aphis fabae) possessing different defensive symbiont strains (Hamiltonella defensa). After ten generations of experimental evolution, wasps showed increased abilities to parasitize aphids possessing the H. defensa strain they evolved with, but not aphids possessing the...
Data from: Plio-Pleistocene phylogeography of the Southeast Asian Blue Panchax killifish, Aplocheilus panchaxSamantha V. Beck, Gary R. Carvalho, Axel Barlow, Lukas Rüber, Heok Hui Tan, Estu Nugroho, Daisy Wowor, Siti Azizah Mohd Nor, Fabian Herder, Zainal A. Muchlisin & Mark De Bruyn
The complex climatic and geological history of Southeast Asia has shaped this region’s high biodiversity. In particular, sea level fluctuations associated with repeated glacial cycles during the Pleistocene both facilitated, and limited, connectivity between populations. In this study, we used data from two mitochondrial and three anonymous nuclear markers to determine whether a fresh/brackish water killifish, Aplocheilus panchax, Hamilton, 1822, could be used to further understand how climatic oscillations and associated sea level fluctuations have...
Data from: The impact of even-aged and uneven-aged forest management on regional biodiversity of multiple taxa in European beech forestsPeter Schall, Martin M. Gossner, Steffi Heinrichs, Markus Fischer, Steffen Boch, Daniel Prati, Kirsten Jung, Vanessa Baumgartner, Stefan Blaser, Stefan Böhm, Francois Buscot, Rolf Daniel, Kezia Goldmann, Kirstin Kaiser, Tiemo Kahl, Markus Lange, Jörg Müller, Jörg Overmann, Swen C. Renner, Ernst-Detlef Schulze, Johannes Sikorski, Marco Tschapka, Manfred Türke, Wolfgang W. Weisser, Bernd Wemheuer … & Kristin Kaiser
For managed temperate forests, conservationists and policymakers favour fine-grained uneven-aged management over more traditional coarse-grained even-aged management, based on the assumption that within-stand habitat heterogeneity enhances biodiversity. There is, however, little empirical evidence to support this assumption. We investigated for the first time how differently grained forest management systems affect the biodiversity of multiple above- and below-ground taxa across spatial scales. We sampled 15 taxa of animals, plants, fungi and bacteria within the largest contiguous...
Data from: Rapid transgenerational effects in Knautia arvensis in response to plant-community diversityTanja Rottstock, Volker Kummer, Markus Fischer & Jasmin Joshi
1. Plant-species persistence in natural communities requires coping with biotic and abiotic challenges. These challenges also depend on plant-community composition and diversity. Over time, biodiversity effects have been shown to be strengthened via increasing species complementarity in mixtures. Little is known, however, whether differences in community diversity and composition induce rapid transgenerational phenotypic adaptive differentiation during community assembly. We expect, altered plant-plant and other biotic interactions (mutualists or antagonists) in high vs. low diverse communities...
Data from: Ancient and modern DNA reveal dynamics of domestication and cross-continental dispersal of the dromedaryFaisal 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: Resistance to RHD virus in wild Australian rabbits: comparison of susceptible and resistant individuals using a genomewide approachNina I. Schwensow, Harald Detering, Stephen Pederson, Camila Mazzoni, Ron Sinclair, David Peacock, John Kovaliski, Brian Cooke, Joerns Fickel & Simone Sommer
Deciphering the genes involved in disease resistance is essential if we are to understand host–pathogen coevolutionary processes. The rabbit haemorrhagic disease virus (RHDV) was imported into Australia in 1995 as a biocontrol agent to manage one of the most successful and devastating invasive species, the European rabbit (Oryctolagus cuniculus). During the first outbreaks of the disease, RHDV caused mortality rates of up to 97%. Recently, however, increased genetic resistance to RHDV has been reported. Here,...
Data from: Broad and flexible stable isotope niches in invasive non-native Rattus spp. in anthropogenic and natural habitats of central eastern MadagascarMelanie Dammhahn, Toky M. Randriamoria & Steven M. Goodman
Background: Rodents of the genus Rattus are among the most pervasive and successful invasive species, causing major vicissitudes in native ecological communities. A broad and flexible generalist diet has been suggested as key to the invasion success of Rattus spp. Here, we use an indirect approach to better understand foraging niche width, plasticity, and overlap within and between introduced Rattus spp. in anthropogenic habitats and natural humid forests of Madagascar. Results: Based on stable carbon...
Recent reports of increasing iron (Fe) concentrations in freshwaters are of concern, given the fundamental role of Fe in biogeochemical processes. Still, little is known about the frequency and geographical distribution of Fe trends, or about the underlying drivers. We analyzed temporal trends of Fe concentrations across 340 water bodies distributed over 10 countries in northern Europe and North America in order to gain a clearer understanding of where, to what extent, and why Fe...
Data from: Neighbourhood effects on plant reproduction: an experimental-analytical framework and its application to the invasive Senecio inaequidensSusanne Lachmuth, Colette Henrichmann, Juliane Horn, Joern Pagel & Frank M. Schurr
1. Density-dependence is of fundamental importance for population and range dynamics. Density-dependent reproduction of plants arises from competitive and facilitative plant-plant interactions that can be pollination-independent or pollination-mediated. In small and sparse populations, conspecific density-dependence often turns from negative to positive and causes Allee effects. Reproduction may also increase with heterospecific density (community-level Allee effect), but the underlying mechanisms are poorly understood and the consequences for community dynamics can be complex. Allee effects have crucial...
Data from: Too hot to die? The effects of vegetation shading on past, present, and future activity budgets of two diurnal skinks from arid AustraliaAnnegret Grimm-Seyfarth, Jean-Baptiste Mihoub & Klaus Henle
Behavioral thermoregulation is an important mechanism allowing ectotherms to respond to thermal variations. Its efficiency might become imperative for securing activity budgets under future climate change. For diurnal lizards, thermal microhabitat variability appears to be of high importance, especially in hot deserts where vegetation is highly scattered and sensitive to climatic fluctuations. We investigated the effects of a shading gradient from vegetation on body temperatures and activity timing for two diurnal, terrestrial desert lizards, Ctenotus...
Data from: Rapid evolution of symbiont-mediated resistance compromises biological control of aphids by parasitoidsHeidi Kaech, Hugo Mathé-Hubert, Alice Dennis, Christoph Vorburger & Alice B. Dennis
There is growing interest in biological control as a sustainable and environmentally friendly way to control pest insects. Aphids are among the most detrimental agricultural pests worldwide, and parasitoid wasps are frequently employed for their control. The use of asexual parasitoids may improve the effectiveness of biological control because only females kill hosts and because asexual populations have a higher growth rate than sexuals. However, asexuals may have a reduced capacity to track evolutionary change...
Data from: The strength of negative plant-soil feedback increases from the intraspecific to the interspecific and the functional group levelAlexandra R. Bukowski, Conrad Schittko & Jana S. Petermann
1. One of the processes that may play a key role in plant species coexistence and ecosystem functioning is plant-soil feedback, the effect of plants on associated soil communities and the resulting feedback on plant performance. Plant-soil feedback at the interspecific level (comparing growth on own soil with growth on soil from different species) has been studied extensively, while plant-soil feedback at the intraspecific level (comparing growth on own soil with growth on soil from...
Identifying behavioral mechanisms that underlie observed movement patterns is difficult when animals employ sophisticated cognitive-based strategies. Such strategies may arise when timing of return visits is important, for instance to allow for resource renewal or territorial patrolling. We fitted spatially explicit random-walk models to GPS movement data of six wolves (Canis lupus; Linnaeus, 1758) from Alberta, Canada to investigate the importance of the following: (1) territorial surveillance likely related to renewal of scent marks along...
