Data from: Arctic and boreal paleofire records reveal drivers of fire activity and departures from Holocene variability

Tyler Hoecker, Philip Higuera, Ryan Kelly & Feng Sheng Hu
Boreal forest and tundra biomes are key components of the Earth system because the mobilization of large carbon stocks and changes in energy balance could act as positive feedbacks to ongoing climate change. In Alaska, wildfire is a primary driver of ecosystem structure and function, and a key mechanism coupling high-latitude ecosystems to global climate. Paleoecological records reveal sensitivity of fire regimes to climatic and vegetation change over centennial-millennial time scales, highlighting increased burning concurrent...

Honey bee virus causes context-dependent changes in host social behavior

Adam Dolezal, Tim Gernat, Geffre Amy, Gyan Harwood, Beryl Jones, Adam Hamilton, Bryony Bonning, Amy Toth, Gene Robinson & Deisy Morselli Gysi
Anthropogenic changes create evolutionarily novel environments that present opportunities for emerging diseases, potentially changing the balance between host and pathogen. Honey bees provide essential pollination services, but intensification and globalization of honey bee management has coincided with increased pathogen pressure, primarily due to a parasitic mite/virus complex. Here, we investigated how honey bee individual and social phenotypes are altered by a virus of concern, Israeli acute paralysis virus (IAPV). Using automated and manual behavioral monitoring...

Genomic evidence for correlated trait combinations and antagonistic selection contributing to counterintuitive genetic patterns of adaptive diapause divergence in Rhagoletis flies

McCall Calvert, Meredith Doellman, Jeffrey Feder, Glenn Hood, Peter Meyers, Scott Egan, Thomas Powell, Mary Glover, Cheyenne Tait, Hannes Schuler, Stewart Berlocher, James Smith, Patrik Nosil, Dan Hahn & Gregory Ragland
Adaptation to novel environments often results in unanticipated genomic responses to selection. Here, we illustrate how multifarious, correlational selection helps explain a counterintuitive pattern of genetic divergence between the recently derived apple- and ancestral hawthorn-infesting host races of Rhagoletis pomonella (Diptera: Tephritidae). The Apple host race terminate diapause and emerge as adults earlier in the season than the hawthorn host race to coincide with the earlier fruiting phenology of their apple hosts. However, alleles at...
