Relationships among wood-boring beetles, fungal endophytes and saprotrophs, and the decomposition of forest biomass.

James Skelton, Michelle Jusino, Paige Carlson, Katherine Smith, Mark Banik, Daniel Linder, Jonathan Palmer & Jiri Hulcr
A prevailing paradigm in forest ecology is that wood-boring beetles facilitate wood decay and carbon cycling, but empirical tests have yielded mixed results. We experimentally determined the effects of wood borers on fungal community assembly and wood decay within pine trunks in the southeastern United States. Pine trunks were made either beetle-accessible or inaccessible. Fungal communities were compared using culturing and high-throughput meta-barcode sequencing of DNA and RNA. Prior to beetle infestation, living pines had...

Effects of social structure and management on risk of disease establishment in wild pigs

Anni Yang, Peter Schlichting, Bethany Wight, Wesley Anderson, Sarah Chinn, Mark Wilber, Ryan Miller, James Beasley, Raoul Boughton, Kurt VerCauteren, George Wittemyer & Kim Pepin
1. Contact heterogeneity among hosts determines invasion and spreading dynamics of infectious disease, thus its characterization is essential for identifying effective disease control strategies. Yet, little is known about the factors shaping contact networks in many wildlife species and how wildlife management actions might affect contact networks. 2. Wild pigs in North America are an invasive, socially-structured species that pose a health concern for domestic swine given their ability to transmit numerous devastating diseases such...

Bumble bees in landscapes with abundant floral resources have lower pathogen loads

Darin McNeil, Elyse McCormick, Ashley C. Heimann, Melanie Kammerer, Margaret R. Douglas, Sarah C. Goslee, Christina M. Grozinger & Heather M. Hines
AbstractThe pollination services provided by bees are essential for supporting natural and agricultural ecosystems. However, bee population declines have been documented across the world. Many of the factors known to undermine bee health (e.g., poor nutrition) can decrease immunocompetence and, thereby, increase bees’ susceptibility to diseases. Given the myriad of stressors that can exacerbate disease in wild bee populations, assessments of the relative impact of landscape habitat conditions on bee pathogen prevalence are needed to...
