Data from: Contact and contagion: bighorn sheep demographic states vary in probability of transmission given contact

Kezia R. Manlove, E. Frances Cassirer, Raina K. Plowright, Paul C. Cross & Peter J. Hudson
1. Understanding both contact and probability of transmission given contact are key to managing wildlife disease. However, wildlife disease research tends to focus on contact heterogeneity, in part because probability of transmission given contact is notoriously difficult to measure. Here we present a first step toward empirically investigating probability of transmission given contact in free-ranging wildlife. 2. We used measured contact networks to test whether bighorn sheep demographic states vary systematically in infectiousness or susceptibility...

Data from: Analysis of local-scale background concentrations of methane and other gas-phase species in the Marcellus Shale

J. Douglas Goetz, Anita Avery, Ben Werden, Cody Floerchinger, Edward C. Fortner, Joda Wormhoudt, Paola Massoli, Scott C. Herndon, Charles E. Kolb, W. Berk Knighton, Jeff Peischl, Carsten Warneke, Joost A. De Gouw, Stephanie L. Shaw & Peter F. DeCarlo
The Marcellus Shale is a rapidly developing unconventional natural gas resource found in part of the Appalachian region. Air quality and climate concerns have been raised regarding development of unconventional natural gas resources. Two ground-based mobile measurement campaigns were conducted to assess the impact of Marcellus Shale natural gas development on local scale atmospheric background concentrations of air pollution and climate relevant pollutants in Pennsylvania. The first campaign took place in Northeastern and Southwestern PA...

Data from: Age-specific infectious period shapes dynamics of pneumonia in bighorn sheep

Superspreading, the phenomenon where a small proportion of individuals contribute disproportionately to new infections, has profound effects on disease dynamics. Superspreading can arise through variation in contacts, infectiousness or infectious periods. The latter has received little attention, yet it drives the dynamics of many diseases of critical public health, livestock health and conservation concern. Here, we present rare evidence of variation in infectious periods underlying a superspreading phenomenon in a free-ranging wildlife system. We detected...

Data from: A new subfamily classification of the Leguminosae based on a taxonomically comprehensive phylogeny

Clark, Manuel De La Estrella, Peter Gasson, GeoffreyC. Kite, BenteB. Klitgaard, GwilymP. Lewis, Danilo Neves, Gerhard Prenner, María De Lourdes Rico-Arce, ArianeR. Barbosa, Maria Cristina López-Roberts, Luciano Paganucci De Queiroz, PétalaG. Ribeiro … & Tingshuang Yi
The classification of the legume family proposed here addresses the long-known non-monophyly of the traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies. This new classification uses as its framework the most comprehensive phylogenetic analyses of legumes to date, based on plastid matK gene sequences, and including near-complete sampling of genera (698 of the currently recognised 765 genera) and ca. 20% (3696) of known species. The matK gene region has been the most...

Data from: Predictors and immunological correlates of sublethal mercury exposure in vampire bats

Daniel J. Becker, Matthew M. Chumchal, Alexandra B. Bentz, Steven G. Platt, Gábor A. Czirják, Thomas R. Rainwater, Sonia Altizer & Daniel G. Streicker
Mercury (Hg) is a pervasive heavy metal that often enters the environment from anthropogenic sources such as gold mining and agriculture. Chronic exposure to Hg can impair immune function, reducing the ability of animals to resist or recover from infections. How Hg influences immunity and susceptibility remains unknown for bats, which appear immunologically distinct from other mammals and are reservoir hosts of many pathogens of importance to human and animal health. We here quantify total...

Data from: Disentangling competitive versus climatic drivers of tropical forest mortality

Michiel Pillet, Emilie Joetzjer, Camille Belmin, Jérôme Chave, Philippe Ciais, Aurélie Dourdain, Margaret Evans, Bruno Hérault, Sebastiaan Luyssaert & Benjamin Poulter
1. Tropical forest mortality is controlled by biotic and abiotic processes, but how these processes interact to determine forest structure is not well understood. Using long-term demography data from permanent forest plots at the Paracou Tropical Forest Research Station in French Guiana, we analyzed the relative influence of competition and climate on tree mortality. We found that self-thinning is evident at the stand level, and is associated with clumped mortality at smaller scales (< 2...

Data from: Modern pollen from small hollows reflects Athrotaxis cupressoides density across a wildfire gradient in subalpine forests of the Central Plateau, Tasmania, Australia

Philip E. Higuera, Jesse L. Morris, Simon Haberle & Cathy Whitlock
Pollen assemblages from 50 small hollows were used to resolve fire-caused vegetation patterns in a ~2-km2 subalpine landscape on the Central Plateau of Tasmania, Australia. Sites were characterized by varying abundance of the dominant tree species, Athrotaxis cupressoides, reflecting mortality from a wildfire that occurred 53 years prior to sampling. Sites were classified a priori based on fire-related Athrotaxis mortality as burned (100% standing dead), unburned (<5% standing dead), and mixed (intermediate proportions). Non-parametric analysis...

Data from: Intraspecific variability and reaction norms of forest understory plant species traits

Julia I. Burton, Steven S. Perakis, Sean C. McKenzie, Caitlin E. Lawrence & Klaus J. Puettmann
1.Trait-based models of ecological communities typically assume intraspecific variation in functional traits is not important, though such variation can change species trait rankings along gradients in resources and environmental conditions, and thus influence community structure and function. 2. We examined the degree of intraspecific relative to interspecific variation, and reaction norms of 11 functional traits for 57 forest understory plant species, including: intrinsic water-use efficiency (iWUE), Δ15N, 5 leaf traits, 2 stem traits and 2...
