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: Fire-regime complacency and sensitivity to centennial- through millennial-scale climate change in Rocky Mountain subalpine forests, Colorado, U.S.A.

Philip E. Higuera, Christy E. Briles & Cathy Whitlock
1. Key uncertainties in anticipating future fire regimes are their sensitivity to climate change, and the degree to which climate will impact fire regimes directly, through increasing the probability of fire, versus indirectly, through changes in vegetation and landscape flammability. 2. We studied the sensitivity of subalpine forest fire regimes (i.e., fire frequency, fire severity) to previously documented climate variability over the past 6000 years, utilizing pollen and macroscopic charcoal from high-resolution lake-sediment records in...

Data from: Chloroplast primers for clade-wide phylogenetic studies of Thalictrum (Ranunculaceae)

Diego Fernando Morales-Briones, Tatiana Arias, Verónica Di Stilio & David C. Tank
Premise Chloroplast primers were developed for phylogenetic and comparative studies in Thalictrum (Ranunculaceae). Methods and Results We assembled and annotated the complete plastome sequence of T. thalictroides by combining multiple whole genome sequencing libraries. Using transcriptome‐sequencing libraries, we also assembled a partial plastome of the related species T. hernandezii. From the newly assembled plastomes and one previously sequenced plastome, we designed and validated 28 primer pairs to target variable portions of the chloroplast genome in...

Data from: Antibiotics as chemical warfare across multiple taxonomic domains and trophic levels

Jane M Lucas, Evan Gora & Michael Kaspari
Bacteria and fungi secrete antibiotics to suppress and kill other microbes, but can these compounds be agents of competition against macroorganisms? We explore how one competitive tactic, antibiotic production, can structure the composition and function of brown food webs. This aspect of warfare between microbes and invertebrates is particularly important today as antibiotics are introduced into ecosystems via anthropogenic activities, but the ecological implications of these introductions are largely unknown. We hypothesized that antimicrobial compounds...

Data from: Divergence before and after the isolation of islands: phylogeography of the Bradybaena land snails on the Ryukyu Islands of Japan

Takahiro Hirano, Yuichi Kameda, Takumi Saito & Satoshi Chiba
Aim: Vicariance events have been proposed as a major source of lineage divergence on continental islands, whereas dispersal events followed by isolation have been proposed as the major cause on oceanic islands. However, organisms on continental islands may include taxa with characteristics similar to those on oceanic islands. Lineage divergence unassociated with the geological events that separated islands may also have occurred. This study addresses these possibilities through morphological and molecular phylogeographic analyses of land...

Data from: Determinants of elephant foraging behavior in a coupled human-natural system: is brown the new green?

Paola S. Branco, Jerod A. Merkle, Robert M. Pringle, Johan Pansu, Arjun B. Potter, Alana Reynolds, Marc Stalmans & Ryan A. Long
1. Crop raiding by wildlife poses major threats to both wildlife conservation and human wellbeing in agro-ecosystems worldwide. These threats are particularly acute in many parts of Africa, where crop raiders include globally threatened megafauna such as elephants, and where smallholder agriculture is a primary source of human livelihood. One framework for understanding herbivore feeding behavior, the forage-maturation hypothesis, predicts that herbivores should align their movements with intermediate forage biomass (i.e., peak green-up); this phenomenon...

Data from: Integrating life history traits into predictive phylogeography

Jack Sullivan, Megan L. Smith, Anahi Espindola, Megan Ruffley, Andrew Rankin, David Tank & Bryan Carstens
Predictive phylogeography seeks to aggregate genetic, environmental and taxonomic data from multiple species in order to make predictions about unsampled taxa using machine-learning techniques such as Random Forests. To date, organismal trait data have infrequently been incorporated into predictive frameworks due to difficulties inherent to the scoring of trait data across a taxonomically broad set of taxa. We refine predictive frameworks from two North American systems, the inland temperate rainforests of the Pacific Northwest (PNW)...

Data from: Cascading impacts of large-carnivore extirpation in an African ecosystem

Justine L. Atkins, Ryan A. Long, Johan Pansu, Joshua H. Daskin, Arjun B. Potter, Marc E. Stalmans, Corina E. Tarnita & Robert M. Pringle
The world’s largest carnivores are declining and now occupy mere fractions of their historical ranges. Theory predicts that when apex predators disappear, large herbivores should become less fearful, occupy new habitats, and modify those habitats by eating new food plants. Yet experimental support for this prediction has been difficult to obtain in large-mammal systems. Following the extirpation of leopards and African wild dogs from Mozambique’s Gorongosa National Park, forest-dwelling antelopes (bushbuck, Tragelaphus sylvaticus) expanded into...

An experimental test of community-based strategies for mitigating human-wildlife conflict around protected areas

Ryan Long, Paola Branco, Jerod Merkle, Robert Pringle, Lucy King, Tosca Tindall & Marc Stalmans
Natural habitats are rapidly being converted to cultivated croplands, and crop-raiding by wildlife threatens both wildlife conservation and human livelihoods worldwide. We combined movement data from GPS-collared elephants with camera-trap data and local reporting systems in a before-after-control-impact design to evaluate community-based strategies for reducing crop raiding outside Mozambique’s Gorongosa National Park. All types of experimental fences tested (beehive, chili, beehive and chili combined, and procedural controls) significantly reduced the number of times elephants left...

Data from: Variation in selective regimes drives intraspecific variation in life-history traits and migratory behaviour along an elevational gradient

Carl Lundblad & Courtney Conway
Comparative studies, across and within taxa, have made important contributions to our understanding of the evolutionary processes that promote phenotypic diversity. Trait variation along geographic gradients provides a convenient heuristic for understanding what drives and maintains diversity. Intraspecific trait variation along latitudinal gradients is well-known, but elevational variation in the same traits is rarely documented. Trait variation along continuous elevational gradients, however, provides compelling evidence that individuals within a breeding population may experience different selective...

Predictive multi-scale occupancy models at range-wide extents: effects of habitat and human disturbance on distributions of wetland birds

Bryan Stevens & Courtney Conway
Aim: Predicting distributions is fundamental to ecology, yet hindered by spatially-restricted sampling, scale-dependent relationships, and detection error associated with field surveys. Predictive species distribution models (SDMs) are nonetheless vital for conservation of many species. We developed a framework for building predictive SDMs with multi-scale data, and used it to develop range-wide breeding-season SDMs for 14 marsh bird species of concern. Location: USA. Methods: We built SDMs using data from range-wide surveys conducted over 14 years,...

Data from: Intrinsic traits of woodland caribou Rangifer tarandus caribou calves depredated by black bears Ursus americanus and coyotes Canis latrans

Matthew A. Mumma, Guillaume Bastille-Rousseau, Steve E. Gullage, Colleen E. Soulliere, Shane P. Mahoney & Lisette P. Waits
Individuals in substandard physical condition are predicted to be more vulnerable to predation. Support for this prediction is inconsistent partly as a result of differences across systems in the life histories of predator and prey species. Our objective was to examine the physical condition of woodland caribou (Rangifer tarandus caribou) calves depredated by two predators with different life histories in Newfoundland, Canada. Black bears (Ursus americanus) are capable of chasing calves at high speeds over...

Data from: Consequences of climatic thresholds for projecting fire activity and ecological change

Adam M. Young, Philip E. Higuera, John T. Abatzoglou, Paul A. Duffy & Feng Sheng Hu
Aim: Ecological properties governed by threshold relationships can exhibit heightened sensitivity to climate, creating an inherent source of uncertainty when anticipating future change. We investigated the impact of threshold relationships on our ability to project ecological change outside the observational record (e.g., the 21st century), using the challenge of predicting late‐Holocene fire regimes in boreal forest and tundra ecosystems. Location: Boreal forest and tundra ecosystems of Alaska. Time period: 850–2100 CE. Major taxa studied: Not...

Data from: Convergent evolution of the army ant syndrome and congruence in big-data phylogenetics

Marek L. Borowiec
Army ants are a charismatic group of organisms characterized by a suite of morphological and behavioral adaptations that includes obligate collective foraging, frequent colony relocation, and highly specialized wingless queens. This “army ant syndrome” underlies the ecological success of army ants and its evolution has been the subject of considerable debate. It has been argued to have arisen once or multiple times within the ant subfamily Dorylinae. To address this question in a phylogenetic framework...

Data from: Climate will increasingly determine post-fire tree regeneration success in low-elevation forests, Northern Rockies, USA

Kerry B. Kemp, Philip E. Higuera, Penelope Morgan & John T. Abatzoglou
Climate change is expected to cause widespread shifts in the distribution and abundance of plant species through direct impacts on mortality, regeneration, and survival. At landscape scales, climate impacts will be strongly mediated by disturbances, such as wildfire, which catalyze shifts in species distributions through widespread mortality and by shaping the post‐disturbance environment. We examined the potential for regional shifts in low‐elevation tree species in response to wildfire and climate warming in low‐elevation, dry mixed‐conifer...

Data from: Prolonged exposure to manure from livestock administered antibiotics decreases ecosystem carbon-use efficiency and alters nitrogen cycling

Carl Wepking, Brian Badgley, Jeb Barrett, Katharine Knowlton, Jane Lucas, Kevan Minick, Partha Ray, Sarah Shawver & Michael Strickland
Microbial communities drive soil ecosystem function but are also susceptible to environmental disturbances. We investigated whether exposure to manure sourced from cattle either administered or not administered antibiotics affected microbially-mediated terrestrial ecosystem function. We quantified changes in microbial community composition via amplicon sequencing, and terrestrial elemental cycling via a stable isotope pulse-chase. Exposure to manure from antibiotic-treated cattle caused: i) changes in microbial community structure; and ii) alterations in elemental cycling throughout the terrestrial system....

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...

Data from: Extensive allopolyploidy in the neotropical genus Lachemilla (Rosaceae) revealed by PCR ‐based target enrichment of the nuclear ribosomal DNA cistron and plastid phylogenomics

Diego F. Morales-Briones & David C. Tank
PREMISE OF THE STUDY: Polyploidy has been long recognized as an important force in plant evolution. Previous studies had suggested widespread occurrence of polyploidy and the allopolyploid origin of several species in the diverse Neotropical genus Lachemilla (Rosaceae). Nonetheless, this evidence has relied mostly on patterns of cytonuclear discordance, and direct evidence from nuclear allelic markers is still needed. METHODS: Here we used PCR target enrichment in combination with high throughput sequencing to obtain multiple...
