Data from: Timing of head movements is consistent with energy minimization in walking ungulates

David M. Loscher, Fiete Meyer, Kerstin Kracht & John A. Nyakatura
Many ungulates show a conspicuous nodding motion of the head when walking. Until now, the functional significance of this behaviour remained unclear. Combining in vivo kinematics of quadrupedal mammals with a computer model, we show that the timing of vertical displacements of the head and neck is consistent with minimizing energy expenditure for carrying these body parts in an inverted pendulum walking gait. Varying the timing of head movements in the model resulted in increased...

Data from: Phylogeography of the small Indian civet and origin of introductions to western Indian Ocean islands

Philippe Gaubert, Riddhi Patel, Geraldine Veron, Steve M. Goodman, Maraike Willsch, Raquel Vasconcelos, Andre Lourenço, Marie Sigaud, Fabienne Justy, Bheem Dutt Joshi, Joerns Fickel & Abdreas Wilting
The biogeographic dynamics affecting the Indian subcontinent, East and Southeast Asia during the Plio-Pleistocene has generated complex biodiversity patterns. We assessed the molecular biogeography of the small Indian civet (Viverricula indica) through mitogenome and cytochrome b + control region sequencing of 89 historical and modern samples to (i) establish a time-calibrated phylogeography across the species’ native range and (ii) test introduction scenarios to western Indian Ocean islands. Bayesian phylogenetic analyses identified three geographic lineages (East...

Data from: Honey bees modulate their olfactory learning in the presence of hornet predators and alarm component

Zhengwei Wang, Yufeng Qu, Shihao Dong, Ping Wen, Jianjun Li, Ken Tan & Randolf Menzel
In Southeast Asia the native honey bee species Apis cerana is often attacked by hornets (Vespa velutina), mainly in the period from April to November. During the co-evolution of these two species honey bees have developed several strategies to defend themselves such as learning the odors of hornets and releasing alarm components to inform other mates. However, so far little is known about whether and how honey bees modulate their olfactory learning in the presence...

Data from: Parental and hybrid Daphnia from the D. longispina complex: long-term dynamics in genetic structure and significance of overwintering modes

Johanna Griebel, Sabine Gießler, Mingbo Yin & Justyna Wolinska
In recent decades, hybridization has become a focus of attention because of its role in evolutionary processes. However, little is known about changes in genetic structure within and between parental species and hybrids over time. Here, we studied processes of genetic change in parental species and hybrids from the Daphnia longispina complex (Crustacea, Cladocera) over a period of six years across ten habitats. These cyclical parthenogens respond to fluctuating environments by switching from asexual to...

Data from: Transition from conventional to light-emitting diode street lighting changes activity of urban bats

Daniel Lewanzik & Christian C. Voigt
Light pollution is rapidly increasing and can have deleterious effects on biodiversity, yet light types differ in their effect on wildlife. Among the light types used for street lamps, light-emitting diodes (LEDs) are expected to become globally predominant within the next few years. In a large-scale field experiment, we recorded bat activity at 46 street lights for 12 nights each and investigated how the widespread replacement of conventional illuminants by LEDs affects urban bats: we...

Data from: Divergence of cuticular hydrocarbons in two sympatric grasshopper species and the evolution of fatty acid synthases and elongases across insects

Jonas Finck, Emma L. Berdan, Frieder Mayer, Bernhard Ronacher & Sven Geiselhardt
Cuticular hydrocarbons (CHCs) play a major role in the evolution of reproductive isolation between insect species. The CHC profiles of two closely related sympatric grasshopper species, Chorthippus biguttulus and C. mollis, differ mainly in the position of the first methyl group in major methyl-branched CHCs. The position of methyl branches is determined either by a fatty acid synthase (FAS) or by elongases. Both protein families showed an expansion in insects. Interestingly, the FAS family showed...

Data from: Street lighting: sex-independent impacts on moth movement

Tobias Degen, Oliver Mitesser, Elizabeth K. Perkin, Nina-Sophie Weiß, Martin Oehlert, Emily Mattig & Franz Hölker
1.Artificial lights have become an integral and welcome part of our urban and peri-urban environments. However, recent research has highlighted the potentially negative ecological consequences of ubiquitous artificial light. In particular, insects, especially moths, are expected to be negatively impacted by the presence of artificial lights. Previous research with light traps has shown a male-biased attraction to light in moths. 2.In this study, we sought to determine if street lights could limit moth dispersal and...

Data from: Phenotypic plasticity of mate recognition systems prevents sexual interference between two sympatric leaf beetle species

Tobias Otte, Monika Hilker & Sven Geiselhardt
Maladaptive sexual interactions among heterospecific individuals (sexual interference) can prevent the coexistence of animal species. Thus, the avoidance of sexual interference by divergence of mate recognition systems is crucial for a stable coexistence in sympatry. Mate recognition systems are thought to be under tight genetic control. However, we demonstrate that mate recognition systems of two closely related sympatric leaf beetle species show a high level of host-induced phenotypic plasticity. Mate choice in the mustard leaf...

Data from: Changing the habitat: the evolution of inter-correlated traits to escape from predators

Dirk J. Mikolajewski, Kristin Scharnweber, Bin Jiang, Sebastian Leicht, Ruediger Mauersberger & Frank Johansson
Burst escape speed is an effective and widely used behaviour for evading predators, with burst escape speed relying on several different morphological features. However, we know little about how behavioural and underlying morphological attributes change in concert as a response to changes in selective predation regime. We studied inter-correlated trait differentiation of body shape and burst-swim-mediating morphology in response to a habitat shift related reduction in burst escape speed using larvae of the dragonfly genus...

Data from: No evidence that plant-soil feedback effects of native and invasive plant species under greenhouse conditions are reflected in the field

Conrad Schittko, Christian Runge, Marek Strupp, Sascha Wolff & Susanne Wurst
Plant–soil feedback (PSF) may affect above-ground higher trophic levels in glasshouse experiments, but evidence from field studies on the relevance of these multitrophic interactions for plant performance is lacking. Therefore, we examined whether PSF effects of several native and invasive plant species occur also in the field and influence plant damage by above-ground herbivores. Root zone soil from an abandoned urban field was used as inocula for the PSF experiment. First, we grew eight urban...

In this report, we present the transcriptome of a single accession of Campanula gentilis Kovanda, obtained through the sequencing of both a normalized and a non-normalized cDNA library generated from stem and leaf tissue. The resources we provide include the raw sequence reads, the assembled contigs, the putative open reading frames, the contig/ORF annotations and the normalized as well as non-normalized expression levels.

Data from: Community trees: identifying codiversification in the páramo dipteran community

Bryan Charles Carstens, Michael Gruenstaeudl & Noah M. Reid
Groups of codistributed species that responded in a concerted manner to environmental events are expected to share patterns of evolutionary diversification. However, the identification of such groups has largely been based on qualitative, post hoc analyses. We develop here two methods (PPS, K-F ANOVA) for the analysis of codistributed species that, given a group of species with a shared pattern of diversification, allow empiricists to identify those taxa that do not codiversify (i.e., "outlier" species)....

Data from: Combined analysis of variation in core, accessory and regulatory genome regions provides a super-resolution view into the evolution of bacterial populations

Alan McNally, Yaara Oren, Darren Kelly, Ben Pascoe, Steven Dunn, Tristan Seecharan, Minna Vehkala, Niko Välimäki, Michael B. Prentice, Amgad Ashour, Oren Avram, Tal Pupko, Ulrich Dobrindt, Ivan Literak, Sebastian Guenther, Katharina Schauffler, Lothar H. Wieler, Zong Zhiyong, Samuel K. Sheppard, James O. McInerney, Jukka Corander & Tristan Sreecharan
The use of whole-genome phylogenetic analysis has revolutionized our understanding of the evolution and spread of many important bacterial pathogens due to the high resolution view it provides. However, the majority of such analyses do not consider the potential role of accessory genes when inferring evolutionary trajectories. Moreover, the recently discovered importance of the switching of gene regulatory elements suggests that an exhaustive analysis, combining information from core and accessory genes with regulatory elements could...

Data from: Elevated virulence of an emerging viral genotype as a driver of honeybee loss

Dino P. McMahon, Myrsini E. Natsopoulou, Vincent Doublet, Matthias Fürst, Silvio Weging, Mark J. F. Brown, Andreas Gogol-Döring & Robert J. Paxton
Emerging infectious diseases (EIDs) have contributed significantly to the current biodiversity crisis, leading to widespread epidemics and population loss. Owing to genetic variation in pathogen virulence, a complete understanding of species decline requires the accurate identification and characterization of EIDs. We explore this issue in the Western honeybee, where increasing mortality of populations in the Northern Hemisphere has caused major concern. Specifically, we investigate the importance of genetic identity of the main suspect in mortality,...

Data from: Temporal regularity increases with repertoire complexity in the Australian pied butcherbird’s song

Eathan Janney, Hollis Taylor, Constance Scharff, David Rothenberg, Lucas C. Parra & Ofer Tchernichovski
Music maintains a characteristic balance between repetition and novelty. Here, we report a similar balance in singing performances of free-living Australian pied butcherbirds. Their songs include many phrase types. The more phrase types in a bird's repertoire, the more diverse the singing performance can be. However, without sufficient temporal organization, avian listeners may find diverse singing performances difficult to perceive and memorize. We tested for a correlation between the complexity of song repertoire and the...

Data from: Assessing patterns in introduction pathways of alien species by linking major invasion databases

Wolf-Christian Saul, Helen E. Roy, Olaf Booy, Lucilla Carnevali, Hsuan-Ju Chen, Piero Genovesi, Colin A. Harrower, Philip E. Hulme, Shyama Pagad, Jan Pergl & Jonathan M. Jeschke
1. Preventing the arrival of invasive alien species (IAS) is a major priority in managing biological invasions. However, information on introduction pathways is currently scattered across many databases that often use different categorisations to describe similar pathways. This hampers the identification and prioritisation of pathways in order to meet the main targets of recent environmental policies. 2. Therefore, we integrate pathway information from two major IAS databases, IUCN's Global Invasive Species Database (GISD) and the...

Data from: Bats, primates, and the evolutionary origins and diversification of mammalian gammaherpesviruses

Marina Escalera-Zamudio, Edith Rojas-Anaya, Sergios-Orestis Kolokotronis, Blanca Taboada, Elizabeth Loza-Rubio, Maria L. Méndez-Ojeda, Carlos F. Arias, Nikolaus Osterrieder & Alex D. Greenwood
Gammaherpesviruses (γHVs) are generally considered host specific and to have codiverged with their hosts over millions of years. This tenet is challenged here by broad-scale phylogenetic analysis of two viral genes using the largest sample of mammalian γHVs to date, integrating for the first time bat γHV sequences available from public repositories and newly generated viral sequences from two vampire bat species (Desmodus rotundus and Diphylla ecaudata). Bat and primate viruses frequently represented deep branches...
