Despite a century of research into the factors that generate and maintain biodiversity, we know remarkably little about drivers parasite diversity. To identify mechanisms governing diversity, combined surveys 8100 amphibian hosts with an outdoor experiment tested theory developed for free-living species. Our analyses revealed diversity increased consistently host due to habitat (i.e. host) heterogeneity, secondary contributions from colonisation abundance. Results experiment, in which was...
Illuminating the ecological and evolutionary dynamics of parasites is one most pressing issues facing modern science, critical for basic global economy, human health. Extremely important to this effort are data on disease-causing organisms wild animal hosts (including viruses, bacteria, protozoa, helminths, arthropods, fungi). Here we present an updated version Global Mammal Parasite Database, a database ungulates (artiodactyls perissodactyls), carnivores, primates, make it available...
Free-living species vary substantially in the extent of their spatial distributions. However, distributions parasitic have not been comprehensively compared this context. We investigated which factors most influence geographical mammal parasites. Using Global Mammal Parasite Database we analysed 17 818 individual geospatial records on 1806 parasite (encompassing viruses, bacteria, protozoa, arthropods and helminths) that infect 396 carnivore, ungulate primate host species. As a measure each...
Abstract Forest pathogens are important drivers of tree mortality across the globe, but it is exceptionally challenging to gather and build unbiased quantitative models their impacts. Here we harness rare data set matching spatial scale pathogen invasion, host, disease heterogeneity estimate infection for four most susceptible host species Phytophthora ramorum , an invasive that drives biological cause in a broad geographic region coastal California southwest Oregon. As 2012, current field...
The challenges posed by observing host-pathogen-environment interactions across large geographic extents and over meaningful time scales limit our ability to understand manage wildland epidemics. We conducted a landscape-scale, longitudinal study designed analyze the dynamics of sudden oak death (an emerging forest disease caused Phytophthora ramorum) hierarchical levels ecological interactions, from individual hosts up community broader landscape. From 2004 2011, we annually assessed status...
Abstract Widespread observations of malformed amphibians across North America have generated both concern and controversy. Debates over the causes such malformations—which can affect >50% animals in a population—have continued, likely due to involvement multiple causal factors. Here, we used 13‐year dataset encompassing 53,880 frogs toads from 422 wetlands 42 states conterminous USA test hypotheses relating abnormalities four categories potential drivers: (i) chemical contaminants, (ii)...
The latitudinal diversity gradient (LDG) - in which species richness decreases from the equator toward poles is among most fundamental distributional patterns ecology. Despite expectation that of parasites tracks their hosts, available evidence suggests many exhibit reverse gradients or no pattern, yet rarity large-scale datasets on host-parasite interactions calls into question robustness such trends. Here, we collected parasitological data a host group conservation importance...
Many cooperatively breeding birds exhibit fine-scale spatial genetic structure as a result of restricted dispersal and habitat specialization. Sitta pusilla (Brown-headed Nuthatch) is bird to mature pine-dominated forests the southeastern United States has been undergoing population declines across most its range. We used five polymorphic microsatellite loci developed for this species examine within site in northern Florida well broader among two other sites (a second one southern Georgia)....
