Data from: Molecular xenomonitoring using mosquitoes to map lymphatic filariasis after mass drug administration in American Samoa

Background: Mass drug administration (MDA) programs have dramatically reduced lymphatic filariasis (LF) incidence in many areas around the globe, including American Samoa. As infection rates decline and MDA programs end, efficient and sensitive methods for detecting infections are needed to monitor for recrudescence. Molecular methods, collectively termed ‘molecular xenomonitoring,’ can identify parasite DNA or RNA in human blood-feeding mosquitoes. We tested mosquitoes trapped throughout the inhabited islands of American Samoa to identify areas of possible...

Data from: Comparing rates of springtail predation by web-building spiders using Bayesian inference

Kelton D. Welch, Matthew R. Schofield, Eric G. Chapman & James D. Harwood
A major goal of gut-content analysis is to quantify predation rates by predators in the field, which could provide insights into the mechanisms behind ecosystem structure and function, as well as quantification of ecosystem services provided. However, percent-positive results from molecular assays are strongly influenced by factors other than predation rate, and thus can only be reliably used to quantify predation rates under very restrictive conditions. Here, we develop two statistical approaches, one using a...

Data from: Biodiversity conservation in agriculture requires a multi-scale approach

David J. Gonthier, Katherine K. Ennis, Serge Farinas, Hsun-Yi Hsieh, Aaron L. Iverson, Péter Batáry, Jörgen Rudolphi, Teja Tscharntke, Bradley J. Cardinale, Ivette Perfecto, D. J. Gonthier, B. J. Cardinale, S. Farinas, H.-Y. Hsieh, A. L. Iverson, I. Perfecto, J. Rudolphi, K. K. Ennis, P. Batary & T. Tscharntke
Biodiversity loss—one of the most prominent forms of modern environmental change—has been heavily driven by terrestrial habitat loss and, in particular, the spread and intensification of agriculture. Expanding agricultural land-use has led to the search for strong conservation strategies, with some suggesting that biodiversity conservation in agriculture is best maximized by reducing local management intensity, such as fertilizer and pesticide application. Others highlight the importance of landscape-level approaches that incorporate natural or semi-natural areas in...

Data from: Multiple endosymbiont infections and reproductive manipulations in a linyphiid spider population

Meghan Curry, Leocadia Paliulis, Kelton Welch, James Harwood & Jennifer White
In many arthropods, maternally inherited endosymbiotic bacteria can increase infection frequency by manipulating host reproduction. Multiple infections of different bacteria in a single host population are common, yet few studies have documented concurrent endosymbiont phenotypes or explored their potential interactions. We hypothesized that spiders might be a particularly useful taxon for investigating endosymbiont interactions, because they are host to a plethora of endosymbiotic bacteria and frequently exhibit multiple infections. We established two matrilines from the...

Data from: Predator-prey trophic relationships in response to organic management practices

Jason M. Schmidt, Sarah K. Barney, Mark A. Williams, Ricardo T. Bessin, Timothy W. Coolong & James D. Harwood
A broad range of environmental conditions likely regulate predator-prey population dynamics and impact the structure of these communities. Central to understanding the interplay between predator and prey populations and their importance is characterizing the corresponding trophic interactions. Here we use a well-documented molecular approach to examine the structure of the community of natural enemies preying upon the squash bug, Anasa tristis, a herbivorous cucurbit pest that severely hinders organic squash and pumpkin production in the...
