Data from: Selection for associative learning of color stimuli reveals correlated evolution of this learning ability across multiple stimuli and rewards.

Maartje Liefting, Katja M. Hoedjes, Cécile Le Lann, Hans M. Smid & Jacintha Ellers
We are only starting to understand how variation in cognitive ability can result from local adaptations to environmental conditions. A major question in this regard is to what extent selection on cognitive ability in a specific context affects that ability in general through correlated evolution. To address this question we performed artificial selection on visual associative learning in female Nasonia vitripennis wasps. Using appetitive conditioning in which a visual stimulus was offered in association with...

Data from: Functional group, biomass, and climate change effects on ecological drought in semiarid grasslands

Scott D. Wilson, Daniel R. Schlaepfer, John B. Bradford, William K. Lauenroth, Michael C. Duniway, Sonia A. Hall, Khishigbayar Jamiyansharav, G. Jia, Ariuntsetseg Lkhagva, Seth M. Munson, David A. Pyke & Britta Tietjen
Water relations in plant communities are influenced both by contrasting functional groups (grasses, shrubs) and by climate change via complex effects on interception, uptake and transpiration. We modelled the effects of functional group replacement and biomass increase, both of which can be outcomes of invasion and vegetation management, and climate change on ecological drought (soil water potential below which photosynthesis stops) in 340 semiarid grassland sites over 30-year periods. Relative to control vegetation (climate and...

Data from: Warming impacts on early life stages increase the vulnerability and delay the population recovery of a long-lived habitat-forming macroalga

Pol Capdevila, Bernat Hereu, Roberto Salguero-Gómez, Graciel·La Rovira, Alba Medrano, Emma Cebrian, Joaquim Garrabou, Diego K. Kersting & Cristina Linares
1. Understanding the combined effects of global and local stressors is crucial for conservation and management, yet challenging due to the different scales at which these stressors operate. Here we examine the effects of one of the most pervasive threats to marine biodiversity, ocean warming, on the early life stages of the habitat-forming macroalga Cystoseira zosteroides, its long-term consequences for population resilience and its combined effect with physical stressors. 2. First, we performed a controlled...

Data from: Ecological conditions alter cooperative behaviour and its costs in a chemically defended sawfly

Carita Lindstedt, Antti Miettinen, Dalial Freitak, Tarmo Ketola, Andrés López-Sepulcre, Elina Mäntylä & Hannu Pakkanen
The evolution of cooperation and social behaviour is often studied in isolation from the ecology of organisms. Yet, the selective environment under which individuals evolve is much more complex in nature, consisting of ecological and abiotic interactions in addition to social ones. Here we measured the life-history costs of cooperative chemical defence in a gregarious social herbivore, Diprion pini pine sawfly larvae, and how these costs vary under different ecological conditions. We ran a rearing...

Data from: Intransitive competition is common across five major taxonomic groups and is driven by productivity, competitive rank and functional traits.

1. Competition can be fully hierarchical or intransitive, and this degree of hierarchy is driven by multiple factors, including environmental conditions, the functional traits of the species involved or the topology of competition networks. Studies simultaneously analyzing these drivers of competition hierarchy are rare. Additionally, organisms compete either directly or via interference competition for resources or space, within a local neighbourhood or across the habitat. Therefore, the drivers of competition could change accordingly and depend...

Data from: Costs and benefits of admixture between foreign genotypes and local populations in the field

Jun Shi, Jasmin Joshi, Katja Tielborger, Koen J. F. Verhoeven & Mirka Macel
Admixture is the hybridization between populations within one species. It can increase plant fitness and population viability by alleviating inbreeding depression and increasing genetic diversity. However, populations are often adapted to their local environments and admixture with distant populations could break down local adaptation by diluting the locally adapted genomes. Thus, admixed genotypes might be selected against and be outcompeted by locally adapted genotypes in the local environments. To investigate the costs and benefits of...

Data from: Hodge decomposition of wall shear stress vector fields characterizing biological flows

Faniry H. Razafindrazaka, Pavel Yevtushenko, Konstantin Poelke, Konrad Polthier & Leonid Goubergrits
A discrete boundary-sensitive Hodge decomposition is proposed as a central tool for the analysis of wall shear stress (WSS) vector fields in aortic blood flows. The method is based on novel results for the smooth and discrete Hodge-Morrey-Friedrichs decomposition on manifolds with boundary and subdivides the WSS vector field into five components: gradient (curl-free), co-gradient (divergence-free), and three harmonic fields induced from the boundary, which are called the center, Neumann and Dirichlet fields. First, an...

Data from: Ecological stasis in Spinicaudata (Crustacea, Branchiopoda)? Early Cretaceous clam shrimp of the Yixian Formation of north‐east China occupied a broader realized ecological niche than extant members of the group

Manja Hethke, Franz T. Fürsich, Baoyu Jiang, Bo Wang, Patrick Chellouche & Stephen C. Weeks
The palaeoecology of Spinicaudata, the dominant group of benthic invertebrates in many pre-Cenozoic freshwater environments, remains poorly understood. In analogy with extant taxa, it has been oversimplified and often reduced to shallow, temporary environments characterised by few trophic levels, implying ecological stasis from the Devonian to the Recent. We excavated 43 horizons of the Lower Cretaceous Yixian Formation (Anjiagou and Hengdaozi beds) to evaluate whether spinicaudatan ecology can be simplified to such an extent. Sedimentological...

Data from: Legacy effects of herbivory enhance performance and resistance of progeny plants

Dinesh Kafle & Susanne Wurst
1. Herbivory-induced changes in plant resistance and tolerance traits can mediate the interaction between spatially and temporally separated above- and belowground herbivores. However, it is unknown how long the impact of transient herbivory events last or if legacy effects can be detected systemically in the plant and across plant generations. 2. Here, we studied the impact of transient aboveground herbivory by the specialist caterpillar Manduca sexta on the plant traits of wild tobacco Nicotiana attenuata...

Data from: Spatial and topical imbalances in biodiversity research

Laura Tydecks, Jonathan Jeschke, Max Wolf, Gabriel Singer, Klement Tockner & Jonathan M. Jeschke
The rapid erosion of biodiversity is among the biggest challenges human society is facing. Concurrently, major efforts are in place to quantify changes in biodiversity, to understand the consequences for ecosystem functioning and human wellbeing, and to develop sustainable management strategies. Based on comprehensive bibliometric analyses covering 134,321 publications, we report systematic spatial biases in biodiversity-related research. Research is dominated by wealthy countries, while major research deficits occur in regions with disproportionately high biodiversity as...

Data from: Daphnia galeata and D. dentifera are geographically and ecologically separated whereas their hybrids occur in intermediate habitats: a survey of 44 Chinese lakes

Xiaolin Ma, Wei Hu, Petr Smilauer, Mingbo Yin & Justyna Wolinska
The idea that hybridization promotes range expansion has received recent attention, but support from field studies is limited. We hypothesized that in the cladoceran waterflea Daphnia, parental species are geographically and ecologically separated, whereas hybrids occupy intermediate or occasionally extreme environments, potentially facilitating range expansion of parental species. We assessed the distribution of Daphnia dentifera, D. galeata and their interspecific hybrids across 44 lakes in China (using mitochondrial and microsatellite markers), and related it to...

Data from: Diversity patterns of non-mammalian cynodonts (Synapsida, Therapsida) and the impact of taxonomic practice and research history on diversity estimates

Marcus Lukic-Walther, Neil Brocklehurst, Christian F. Kammerer & Jörg Fröbisch
Non-mammalian cynodonts represent a speciose and ecologically diverse group with a fossil record stretching from the late Permian until the Cretaceous. Because of their role as major components of Triassic terrestrial ecosystems and as the direct ancestors of mammals, cynodonts are an important group for understanding Mesozoic tetrapod diversity. We examine patterns of non-mammalian cynodont species richness and the quality of their fossil record. A supertree of cynodonts is constructed from recently published trees and...
