Species specific plant-mediated effects between herbivores converge at high damage intensity

Jinlong Wan, Jiahui Yi, Zhibin Tao, Zhikun Ren, Evans Otieno, Baoliang Tian, Jianqing Ding, Evan Siemann, Matthias Erb & Wei Huang
Plants are often exposed to multiple herbivores and densities of these attackers (or corresponding damage intensities) generally fluctuate greatly in the field. Plant-mediated interactions vary among herbivore species and with changing feeding intensity, but little is known about how herbivore identity and density interact to determine plant responses and herbivore fitness. Here, we investigated this question using Triadica sebifera (tallow) and its two major specialist insect herbivores, Bikasha collaris (flea beetle) and Heterapoderopsis bicallosicollis (weevil)....

Projected climate risk of aquatic food system benefits

Michelle Tigchelaar, William Cheung, Essam Mohammed, Michael Phillips, Hanna Payne, Elizabeth Selig, Colette Wabnitz, Muhammed Oyinlola, Thomas Frölicher, Jessica Gephart, Christopher Golden, Edward Allison, Abigail Bennett, Ling Cao, Jessica Fanzo, Benjamin Halpern, Fiorenza Micheli, Rosamond Naylor, Rashid Sumaila, Alessandro Tagliabue & Max Troell
Aquatic foods from marine and freshwater systems are critical to the nutrition, health, livelihoods, economies and culture of billions of people worldwide – but climate-related hazards may compromise their ability to provide these benefits. This analysis estimates national-level aquatic food system climate risk using a fuzzy logic modeling approach that connects climate hazards impacting marine and freshwater capture fisheries and aquaculture to their contributions to sustainable food system outcomes, and vulnerability to losing those contributions....

Adaptive population structure shifts in invasive parasitic mites, Varroa destructor

Arrigo Moro, Tjeerd Blacquière, Bjorn Dahle, Vincent Dietemann, Yves Le Conte, Locke Barbara, Peter Neumann & Alexis Beaurepaire
Comparative studies of genetic diversity and population structure can shed light on the ecological and evolutionary factors governing host–parasite interactions. Even though invasive parasites are considered of major biological importance, little is known about their adaptive potential when infesting the new hosts. Here, the genetic diversification of Varroa destructor, a novel parasite of Apis mellifera originating from Asia, was investigated using population genetics to determine how the genetic structure of the parasite changed in distinct...

Location – Lowland rain forest in south Korup National Park, in the Southwest Region of Cameroon. Material and methods –...

Data from: Changes in liana density over 30 years in a Bornean rain forest supports the escape hypothesis

David Newbery, Cedric Zahnd & Elaine Campbell
In two permanent plots of lowland dipterocarp forest at Danum a liana census in 1988 was repeated in 2018 using the same method. Trees ≥ 30 cm gbh (girth at breast height) were recorded for number of lianas ≥ 2 cm gbh on their stems. The forest was evidently in a late stage of recovery from a large natural disturbance. Over the interval, mean number of lianas per tree decreased by 22 and 34 %...

The neonicotinoid thiamethoxam impairs male fertility in solitary bees, Osmia cornuta

Lars Straub & Verena Strobl
The ongoing loss of global biodiversity is endangering ecosystem functioning and human food security. While environmental pollutants are well known to reduce fertility, the potential effects of common neonicotinoid insecticides on insect fertility remain poorly understood. Here, we show that field-realistic neonicotinoid exposure can drastically impact male insect fertility. In the laboratory, male and female solitary bees Osmia cornuta were exposed to four concentrations of the neonicotinoid thiamethoxam to measure survival, food consumption, and sperm...

Impact of Pleistocene eustatic fluctuations on evolutionary dynamics in Southeast Asian biodiversity hotspots

Arni Sholihah, Erwan Delrieu-Trottin, Fabien Condamine, Daisy Wowor, Lukas Rüber, Laurent Pouyaud, Jean-François Agnèse & Nicolas Hubert
Pleistocene Climatic Fluctuations (PCF) are frequently highlighted as important evolutionary engines that triggered cycles of biome expansion and contraction. While there is ample evidence of the impact of PCF on biodiversity for continental biomes, the consequences in insular systems depend on the geology of the islands and the ecology of the taxa inhabiting them. The idiosyncratic aspects of insular systems are exemplified by the islands of the Sunda Shelf in Southeast Asia (Sundaland), where PCF-induced...

Earthworm invasion causes declines across soil fauna size classes and biodiversity facets in northern North American forests

Malte Jochum, Olga Ferlian, Madhav Thakur, Marcel Ciobanu, Bernhard Klarner, Jörg-Alfred Salamon, Lee Frelich, Ed Johnson & Nico Eisenhauer
Anthropogenic pressures alter the biodiversity, structure, and organization of biological communities with severe consequences for ecosystem processes. Species invasion is such a human-induced ecosystem change with pronounced impacts on recipient ecosystems. Around the globe, earthworms invade habitats and impact abiotic soil conditions and a wide range of above- and belowground organisms. In northern North America, where earthworms have been largely absent since the last glaciation period and most earthworm species present today have only been...

Red-billed chough (Pyrrhocorax pyrrhocorax) models

Veronika Braunisch, Sergio Vignali, Pierre-Alain Oggier & Raphael Arlettaz
The absence of a species in apparently suitable regions is often attributed to habitat deterioration, which, according to the IUCN-guidelines, would preclude reintroduction unless the habitat is sufficiently restored. The crux is therefore to determine species’ key habitat requisites and to localize potentially restorable sites based on the habitat selection of thriving populations in similar environments. The distribution of the Red-billed chough (Pyrrhocorax pyrrhocorax) in the Alpine arch is currently restricted to its western side....

Impact of dietary treatments on longevity and body weight of Apis mellifera winter bees

Gina Retschnig, Johannes Rich, Karl Crailsheim, Judith Pfister, Vincent Perreten & Peter Neumann
In eusocial honey bees, Apis mellifera, diet, gut microbiota and nestmates can all contribute to the health of freshly-emerged individual workers, but their relative importance for longevity and body weight is currently unknown. Here, we show that diet is most relevant, followed by gut microbiota and the presence of nestmates. Freshly emerged workers were randomly assigned to eight treatments (with or without honey/pollen, protein-substitute lactalbumin, antibiotic tetracycline and nestmates for 24 h) and maintained under...

Quantity discrimination in a lizard

Birgit Szabo, Daniel W. A. Noble, Martin J. Whiting, Marco E. S. Monteiro & Kaitlin J. McCloghry
While foraging or during social interactions, animals may benefit from judging relative quantity. Individuals may select larger prey or a patch with more food and likewise, it may pay to track the number and type of individuals and social interactions. We tested for spontaneous quantity discrimination in the gidgee skink (Egernia stokesii), a family-living lizard. Lizards were presented with food quantities differing in number or size and selected the larger quantity of food items when...

Species co-occurrence shapes spatial variability in plant diversity–biomass relationships in natural rangelands under different grazing intensities

Anvar Sanaei, Emma J. Sayer, Hugo Saiz, Zuoqiang Yuan & Arshad Ali
Grazing can alter plant species interactions in natural rangelands, which in turn might influence the productivity of the ecosystem but we do not fully understand how spatial variability in plant diversity-biomass relationships are modulated by grazing intensity. Here, we hypothesized that plant species co-occurrence in rangelands is mainly driven by niche segregation due to grazing and heterogeneity in local resources, and that grazing therefore modulates diversity–biomass relationships. We tested our hypothesis across 35 rangeland sites...

A standardized delineation of the worlds’ mountains has many applications in research, education, and the science-policy interface. Here we provide a new inventory of 8616 mountain ranges developed under the auspices of the Global Mountain Biodiversity Assessment (GMBA). Building on an earlier compilation, the presented geospatial database uses a further advanced and generalized mountain definition and a semi-automated method to enable globally standardized, transparent delineations of mountain ranges worldwide. The inventory is presented on EarthEnv...

Acute radiation syndrome-related gene expression in irradiated peripheral blood cell populations

Patrick Ostheim, Alan Don Mallawaratchy, Thomas Müller, Simone Schüle, Cornelius Hermann, Tanja Popp, Stefan Eder, Stephanie E. Combs, Matthias Port & Michael Abend
In a nuclear or radiological event, an early diagnostic tool is needed to distinguish the worried well from those individuals who may later develop life-threatenFing hematologic acute radiation syndrome. We examined the contribution of the peripheral blood's cell populations on radiation-induced gene expression (GE) changes. EDTA-whole-blood from six healthy donors was X-irradiated with 0 and 4Gy and T-lymphocytes, B-lymphocytes, NK-cells and granulocytes were separated using immunomagnetic methods. GE were examined in cell populations and whole...

Dataset from: Warming effects on grassland productivity depend on plant diversity

Junjiong Shao, Xuhui Zhou, Kees Van Groenigen, Guiyao Zhou, Huimin Zhou, Lingyan Zhou, Meng Lu, Jianyang Xia, Lin Jiang, Bruce Hungate, Yiqi Luo, Fangliang He & Madhav Thakur
Aim: Climate warming and biodiversity loss both alter plant productivity, yet we lack an understanding of how biodiversity regulates the responses of ecosystems to warming. In this study, we examine how plant diversity regulates the responses of grassland productivity to experimental warming using meta-analytic techniques. Location: Global Major taxa studied: Grassland ecosystems Methods: Our meta-analysis is based on warming responses of 40 different plant communities obtained from 20 independent studies on grasslands across five continents....

Data from: Including tree spatial extension in the evaluation of neighbourhood competition effects in Bornean rain forest

David Newbery & Peter Stoll
Classical tree neighbourhood models use size variables acting at point distances. In a new approach here, trees were spatially extended as a function of their crown sizes, represented impressionistically as points within crown areas. Extension was accompanied by plasticity in the form of crown removal or relocation under the overlap of taller trees. Root systems were supposedly extended in a similar manner. For the 38 most abundant species in the focal size class (10 -...

Stakeholder priorities determine the impact of an alien tree invasion on ecosystem multifunctionality

Theo Linders, Urs Schaffner, Tena Alamirew, Eric Allan, Simon Choge, René Eschen, Hailu Shiferaw & Peter Manning
1. While the ecological impact of environmental change drivers, such as alien plant invasions, is relatively well-described, quantitative social-ecological studies detailing how these changes impact multiple ecosystem services, and subsequently stakeholders, are lacking. 2. We used a social-ecological approach to assess how Prosopis juliflora (Prosopis henceforth)¸ an invasive tree, affects the provision of multiple ecosystem services to different stakeholder groups in a degraded East African dryland. We combined plot-based ecological data on the impacts of...

Ecological variation drives morphological differentiation in a highly social vertebrate

Annika Freudiger, Dario Josi, Timo Thünken, Fabian Herder, Jana Flury, David Marques, Michael Taborsky & Joachim Frommen
1. Animals may respond to ecological heterogeneity by genetic differentiation or phenotypic plasticity. Responses of organisms to their ecology can include adaptation at various levels of organization, including morphology, behaviour and social structure. Adaptations at one level might con-strain or enhance adaptations on other levels, which highlights the importance of understanding their interactions. 2. In highly social animals, understanding the influence of ecology on the evolution and maintenance of complex social organization poses an intriguing...

Oxygenated polycyclic aromatic hydrocarbon (OPAH) and polycyclic aromatic hydrocarbon (PAH) concentrations in soils with soil properties: A global data set

Wolfgang Wilcke, Moritz Bigalke, Chong Wei, Yongming Han & Benjamin Musa Bandowe
The hazardous oxygenated polycyclic aromatic hydrocarbons (OPAHs) originate from combustion (primary sources) or post-emission conversion of PAHs (secondary sources). We evaluated the global distribution of up to 15 OPAHs in 195 mineral topsoils from 33 study sites (covering 52°N-47°S, 71°W-118°E), to identify indications of primary or secondary sources of OPAHs. The sums of the (frequently measured 7 and 15) OPAH concentrations correlated with those of the S16EPA-PAHs. The relationship of the S16EPA-PAHs concentrations with the...

Data from: Adaptations and responses of the common dandelion to low atmospheric pressure in high altitude environments

Carla Arce, Zoe Bont, Ricardo Machado, Paulo Cristaldo & Matthias Erb
Atmospheric pressure is an important, yet understudied factor that may shape plant ecology and evolution. By growing plants under controlled conditions at different experimental stations in the Swiss alps, we evaluated the impact of ecologically realistic atmospheric pressures between 660 and 950 hPa on the growth and defence of different dandelion populations. Low atmospheric pressure was associated with reduced root growth and defensive sesquiterpene lactone production. Defence suppression only occurred in populations originating from lower...

Analysis of ancestry heterozygosity suggests that hybrid incompatibilities in threespine stickleback are environment-dependent

Ken Thompson, Catherine Peichel, Diana Rennison, Matthew McGee, Arianne Albert, Timothy Vines, Anna Greenwood, Abigail Wark, Yaniv Brandvain, Molly Schumer & Dolph Schluter
Hybrid incompatibilities occur when interactions between opposite-ancestry alleles at different loci reduce the fitness of hybrids. Most work on incompatibilities has focused on those that are 'intrinsic', meaning they affect viability and sterility in the laboratory. Theory predicts that ecological selection can also underlie hybrid incompatibilities, but tests of this hypothesis using sequence data are scarce. In this article, we compiled genetic data for F2 hybrid crosses between divergent populations of threespine stickleback fish (Gasterosteus...

Association of SNPs in Microtus arvalis and clade infections by TULV-CEN.S and TULV-EST.S

Anton Labutin, Moritz Saxenhofer, Thomas White & Gerald Heckel
The natural host ranges of many viruses are restricted to very specific taxa. Little is known about the molecular barriers between species that lead to the establishment of this restriction or generally prevent virus emergence in new hosts. Here, we identify genomic polymorphisms in a natural rodent host associated with a strong genetic barrier to the transmission of the European Tula orthohantavirus (TULV). We analyzed the very abrupt spatial transition between two major phylogenetic clades...
