Data from: Ovipositor and mouthparts in a fossil insect support a novel ecological role for early orthopterans in 300 million years old forests
<p>A high portion of the earliest known, Pennsylvanian, insect fauna is composed of the so-called 'lobeattid insects', which systematic affinities and role as foliage feeders remain debated. We investigated hundreds of samples of a new lobeattid species from the Xiaheyan locality using a combination of photographic techniques, including Reflectance Transforming Imaging, and geometric morphometrics, to document its morphology, and infer its phylogenetic position and ecological role. <i>Ctenoptilus frequens</i> sp. nov. possessed a sword-shaped ovipositor whose valves interlocked by two ball-and-socket mechanisms. This unambiguously supports lobeattids as stem-relatives of all living Orthoptera (crickets, grasshoppers, katydids). Given the herein presented and other remains, it follows that this group experienced an early diversification coupled with high numbers of individuals. The ovipositor shape additionally indicates that ground was the preferred substrate for eggs. Visible mouthparts made it possible to assess the efficiency of the mandibular food uptake system in comparison to a wide array of extant species. The new species was omnivorous which explains the paucity of external damage on contemporaneous plant foliage.</p>
Data from: Tracking migration of black-headed buntings Emberiza melanocephala reveals the Iranian Plateau as an ecological barrier along the Indo-European flyway
<p><strong>Abstract</strong></p> <p>The black-headed bunting is one of the few species that migrate along the Indo- European flyway, and its migration routes and phenology are poorly understood. We provide the first individual-based year-round tracking study describing route choice and timing of black-headed buntings migrating from a breeding site in Croatia to a 6000 km distant non-breeding region in Maharashtra, Central India. To evaluate landscapes important for the black-headed bunting migration, we quantified land covers and climates along the migration corridor. Stopover areas during the post-breeding migration were concentrated in four distinct regions: the Balkan Peninsula, central Anatolia, along with the Zagros Mountain range and from the Indus River delta to the Kathiawar Peninsula. Post-breeding migration routes followed the shortest path connecting breeding and non-breeding sites, except for the initial detour from the breeding sites to the first stopovers at the Balkan Peninsula. The pre-breeding migration routes occur along the Arabian Peninsula, about 1000 km south of the post-breeding routes – creating a clockwise loop migration pattern. Post-breeding migration lasted about two months, whereas pre-breeding migration was almost two times shorter, conforming to energy- and time-minimisation strategies, respectively. During the postbreeding migration, birds seem to track ecological niches found on their breeding grounds. Post-breeding stopover areas were rich in mosaic lands and were in warm and dry climates of Mediterranean character, while forests and bare areas, as well as arid and humid climates, were avoided.</p> <p> </p>
Data from: Drivers and cascading ecological consequences of Gambusia affinis trait variation
<p>Phenotypic trait differences among populations can shape ecological outcomes for communities and ecosystems. However, few studies have mechanistically linked heritable and plastic components of trait variation to generalizable processes of ecology, such as trophic cascades. Here we assess morphological and behavioral trait variation in nine populations of common-garden reared western mosquitofish (<em>Gambusia affinis</em>) from three distinct ancestral predator environments (three populations per environment), each reared in the presence and absence of predator cues. We then use a pond mesocosm experiment to examine the ecological consequences of trait variation and density variation. Our results show significant among-population trait variation, but this variation was generally unrelated to ancestral predator environment. When traits did vary congruently with respect to ancestral predator environment, this trait variation was driven by gene-by-environment interactions. Variation in several mosquitofish traits altered the cascading effects of mosquitofish on zooplankton and primary producers, but the effect of any given trait was typically weaker than that of density. We note that the relatively stronger ecological effects of density may mask the effects of traits in some systems. Our example here shows that trait variation can be highly noncongruent with respect to a perceived selective agent, phenotypic change is a product of complex interactions between genes and the environment, and numerous interacting phenotypes generate significant but potentially cryptic cascading ecological change. </p>

Data for: Metagenomics show high spatiotemporal virus diversity and ecological compartmentalisation: virus infections of melon, Cucumis melo, crops and adjacent wild communities
<p>Emergence of viral diseases results from novel transmission dynamics between wild and crop plant communities. The bias of studies towards pathogenic viruses of crops has distracted from knowledge of non-antagonistic symbioses in wild plants. Here we implemented a high throughput approach to compare the viromes of melon (<em>Cucumis melo</em>)<em>, </em>and wild plants of crop (Crop) and adjacent boundaries (Edge). Each of the 41-plant species examined was infected by at least one virus. The interactions of 104 virus operational taxonomic units (OTUs) with these hosts occurred largely within ecological compartments of either Crop or Edge, Edge having traits of a reservoir community. The positive correlation of virus and plant richness at each site, the tendency for increased specialist host use through seasons, and specialist host use by OTUs observed only in Melon, characterised local-scale patterns of infection. In this study of systematically sampled viromes of crop and adjacent wild communities most hosts showed no disease symptoms, suggesting non-antagonistic symbioses are common. The coexistence of viruses within species-rich ecological compartments of agro-systems might promote the evolution of a diversity of virus strategies for survival and transmission. These communities, including those suspected as reservoirs, are subject to sporadic changes in assemblages, and so too are the conditions that favour the emergence of disease.</p>
