Data from: Dynamic measurements of black oystercatcher (Haematopus bachmani) predation on mussels (Mytilus californianus)

Luke P. Miller & William W. Dowd
Intertidal zone mussels can face threats from a variety of predatory species during high and low tides, and they must balance the threat of predation against other needs such as feeding and aerobic respiration. Black oystercatchers (Haematopus bachmani) on the Pacific coast of North America can depend on the mussel Mytilus californianus for a substantial portion of their diet. Observations suggest that oystercatchers tend to focus on mussels beginning to gape their valves during rising...

Data from: Testing conceptual models of early plant succession across a disturbance gradient

Cynthia C. Chang, Charles B. Halpern, Joseph A. Antos, Meghan L. Avolio, Abir Biswas, James E. Cook, Roger Del Moral, Dylan G. Fischer, Andrés Holz, Robert J. Pabst, Mark E. Swanson & Donald B. Zobel
1.Studies of succession have a long history in ecology, but rigorous tests of general, unifying principles are rare. One barrier to these tests of theory is the paucity of longitudinal studies that span the broad gradients of disturbance severity that characterize large, infrequent disturbances. The cataclysmic eruption of Mount St. Helens (Washington, USA) in 1980 produced a heterogeneous landscape of disturbance conditions, including primary to secondary successional habitats, affording a unique opportunity to explore how...

Data from: Tracing the rise of malignant cell lines: distribution, epidemiology and evolutionary interactions of two transmissible cancers in Tasmanian devils

Samantha James, Geordie Jennings, Young Mi Kwon, Maximilian Stammnitz, Alexandra Fraik, Andrew Storfer, Sebastien Comte, David Pemberton, Samantha Fox, Bill Brown, Ruth Pye, Gregory Woods, Bruce Lyons, Paul Hohenlohe, Hamish McCallum, Hannah V. Siddle, Frederic Thomas, Beata Ujvari, Elizabeth P. Murchison, Menna Jones & Rodrigo Hamede
Emerging infectious diseases are rising globally and understanding host-pathogen interactions during the initial stages of disease emergence is essential for assessing potential evolutionary dynamics and designing novel management strategies. Tasmanian devils (Sarcophilus harrisii) are endangered due to a transmissible cancer – devil facial tumour disease (DFTD) – that since its emergence in the 1990’s, has affected most populations throughout Tasmania. Recent studies suggest that devils are adapting to the DFTD epidemic and that disease-induced extinction...

Data from: Highly diversified crop-livestock farming systems reshape wild bird communities

Olivia Smith, Christina Kennedy, Jeb Owen, Tobin Northfield, Christopher Latimer & William Snyder
Agricultural intensification is a leading threat to bird conservation. Highly diversified farming systems that integrate livestock and crop production might promote a diversity of habitats useful to native birds foraging across otherwise-simplified landscapes. At the same time, these features might be attractive to non-native birds linked to a broad range of disservices to both crop and livestock production. We evaluated the influence of crop-livestock integration on wild bird richness and density along a north-south transect...

Distribution and connectivity of protected areas in the Americas facilitates transboundary conservation

Daniel Thornton, Lyn Branch & Dennis Murray
Large-scale anthropogenic changes to landscapes will cause species to move and shift their ranges against a backdrop of international political boundaries. Transboundary conservation efforts are therefore key to preserving intact and connected landscapes, particularly if such efforts can be implemented within the framework of protected area networks that provide for resiliency and persistence in the face of threats such as climate change. We studied the distribution, connectivity, and integrity of protected areas in regions near...

Occupancy in dynamic systems: accounting for multiple scales and false positives using environmental DNA to inform monitoring

Matthew Smith & Caren Goldberg
Occupancy is an important metric to understand current and future trends in populations that have declined globally. In addition, occupancy can be an efficient tool for conducting landscape-scale and long-term monitoring. A challenge for occupancy monitoring programs is to determine the appropriate spatial scale of analysis and to obtain precise occupancy estimates for elusive species. We used a multi-scale occupancy model to assess occupancy of Columbia spotted frogs in the Great Basin, USA, based on...

Data from: Organic farming promotes biotic resistance to food-borne human pathogens

Matthew S. Jones, Zhen Fu, John P. Reganold, Daniel S. Karp, Thomas E. Besser, Jason M. Tylianakis & William E. Snyder
Farmland biodiversity benefits pollination, biological control and other key ecosystem services. Food safety has been seen as an exception to this broader pattern, as diverse farmlands attract wildlife that vector foodborne human pathogens. Resulting mitigation efforts thus often seek to deter wildlife by removing natural habitats, while also excluding vertebrate livestock. However, surprising recent evidence suggests that farm simplification actually increases the likelihood that produce will be contaminated with human pathogens. Here, we consider the...

Data from: Do scavengers prevent or promote disease transmission? The effect of invertebrate scavenging on Ranavirus transmission

Mitchell J. Le Sage, Bailey D. Towey & Jesse L. Brunner
1. Host-parasite interactions are shaped by the broader web of community interactions, from interspecific competition to predator-prey dynamics. Heterospecific scavengers might also affect parasite transmission from infectious carcasses, which can be an important source of infections for some wildlife diseases. 2. A robust scavenger community can quickly remove carcasses and tissue and thus prevent secondary transmission by necrophagy or contact with infectious carcasses. Alternatively, by spreading infectious particles and tissues throughout the environment, scavengers may...

Data from: Diversification of Hawaiian Cyrtandra (Gesneriaceae) under the influence of incomplete lineage sorting and hybridization

Joseph A Kleinkopf, Wade R Roberts, Warren L Wagner & Eric H Roalson
Cyrtandra (Gesneriaceae) is a genus of flowering plants with over 800 species distributed throughout Southeast Asia and the Pacific Islands. On the Hawaiian Islands, 60 named species and over 89 putative hybrids exist, most of which are identified on the basis of morphology. Despite many previous studies on the Hawaiian Cyrtandra lineage, questions regarding the reconciliation of morphology and genetics remain, many of which can be attributed to the relatively young age and evidence of...

Data from: A self-preserving, partially biodegradable eDNA filter

Austen C. Thomas, Phong L. Nguyen, Jesse Howard & Caren S. Goldberg
1. eDNA studies often rely on water filtration in the field and immediate sample preservation to prevent DNA degradation during sample transport. However, filter membrane transfer steps for preservation can increase risk of sample contamination and the reliance on typical single-use filter housings produces significant plastic waste. 2. We created a new eDNA filter housing (compatible with any suction pump) partially comprised of a biodegradable, hydrophilic material that functions to automatically preserve captured eDNA via...

Future of the human climate niche

Chi Xu, Timothy Kohler, Timothy Lenton, Jens-Christian Svenning & Marten Scheffer
All species have an environmental niche, and despite technological advances, humans are unlikely to be an exception. Here, we demonstrate that for millennia, human populations have resided in the same narrow part of the climatic envelope available on the globe, characterized by a major mode around ∼11 °C to 15 °C mean annual temperature (MAT). Supporting the fundamental nature of this temperature niche, current production of crops and livestock is largely limited to the same...

Beyond the group: how food, mates and group size influence inter-group encounters in wild bonobos

Stefano Lucchesi, Leveda Cheng, Karline Janmaat, Roger Mundry, Anne Pisor & Surbeck Martin
In social-living animals, interactions between groups are frequently agonistic, but they can also be tolerant and even cooperative. Inter-group tolerance and cooperation are regarded as a crucial step in the formation of highly-structured multilevel societies. Behavioral ecological theory suggests that inter-group tolerance and cooperation can emerge either when the costs of hostility outweigh the benefits of exclusive resource access, or when both groups gain fitness benefits through their interactions. However, the factors promoting inter-group tolerance...

Beneficial microbes ameliorate abiotic and biotic sources of stress on plants

Maren Friesen, Stephanie Porter, Roxanne Bantay, Colleen Friel, Kristi Gdanetz, Bethany Moore, Prateek Shetty & Eleanor Siler
1. Global climate change and shifting land-use are increasing plant stress due to abiotic factors such as drought, heat, salinity and cold, as well as via the intensification of biotic stressors such as herbivores and pathogens. The ability of plants to tolerate such stresses is modulated by the bacteria and fungi that live on or inside of plant tissues and comprise the plant microbiome. However, the impacts of diverse classes of beneficial microbes and the...

Data from: Strong patterns of intraspecific variation and local adaptation in Great Basin plants revealed through a review of 75 years of experiments

Owen W. Baughman, Alison C. Agneray, Matthew L. Forister, Francis F. Kilkenny, Erin K. Espeland, Rob Fiegener, Matthew E. Horning, Richard C. Johnson, Thomas N. Kaye, Jeffery Ott, John Bradley St. Clair & Elizabeth A. Leger
Variation in natural selection across heterogeneous landscapes often produces 1) among-population differences in phenotypic traits, 2) trait-by-environment associations, and 3) higher fitness of local populations. Using a broad literature review of common garden studies published between 1941 and 2017, we documented the commonness of these three signatures in plants native to North America’s Great Basin, an area of extensive restoration and revegetation efforts, and asked which traits and environmental variables were involved. We also asked,...

Data from: Rate of inter-sex interactions affects injury likelihood in Tasmanian devil contact networks

David G. Hamilton, Menna E. Jones, Elissa Z. Cameron, Hamish McCallum, Andrew Storfer, Paul A. Hohenlohe & Rodrigo K. Hamede
Identifying the types of contacts that result in disease transmission is important for accurately modelling and predicting transmission dynamics and disease spread in wild populations. We investigated contacts within a population of adult Tasmanian devils (Sarcophilus harrisii) over a six-month period and tested whether individual-level contact patterns were correlated with accumulation of bite wounds. Bite wounds are important in the spread of devil facial tumour disease (DFTD), a clonal cancer cell line transmitted through direct...

Reduced cooperative courtship behavior as a cost of high testosterone in a lekking passerine bird

Ben Vernasco & Ignacio Moore
Many studies have identified the reproductive benefits of cooperative behaviors, yet few have identified the mechanisms that underlie these behaviors. Mechanistic studies can inform our understanding of why some individuals are more or less cooperative as well as identify the physiological constraints imposed upon the evolution of reproductive traits. Male wire-tailed manakins (Pipra filicauda) exhibit cooperative courtship behaviors and more cooperative territory-holders have been shown to exhibit higher reproductive success. To begin to understand the...

Genomic data reveal similar genetic differentiation in aquifer species with different dispersal capabilities and life histories

Steve Jordan, Brian Hand, Scott Hotaling, Amanda DelVecchia, Rachel Malison, Clark Nissley, Gordon Luikart & Jack Standford
Little is known about the life histories, genetic structure, and population connectivity of shallow groundwater organisms. We used next-generation sequencing (RAD-seq) to analyze population genomic structure in two aquifer species: Paraperla frontalis (Banks, 1902), a stonefly with groundwater larvae and aerial (winged) adults, and Stygobromus sp., a groundwater-obligate amphipod. We found similar genetic differentiation in each species between floodplains separated by ~70 river km in the Flathead River basin of NW Montana, USA. Given that...
