Mosquitoes are important vectors for pathogens that infect humans and other vertebrate animals. Some aspects of adult mosquito behavior and mosquito ecology play an important role in determining the capacity of vector populations to transmit pathogens. Here, we re-examine factors affecting the transmission of pathogens by mosquitoes using a new approach. Unlike most previous models, this framework considers the behavioral states and state transitions of adult mosquitoes through a sequence of activity bouts. We developed...

Temporal dynamics of migration-linked genetic variation are driven by streamflows and riverscape permeability

Suzanne Kelson, Michael Miller, Tasha Thompson, Sean O'Rourke & Stephanie Carlson
The permeability of landscapes is often explored spatially, but may also vary across time. For example, highways are more passable with low traffic, and mountain landscapes are more passable once snow-free. Landscape permeability especially influences migratory animals. Partial barriers are features that are passable in some conditions. Partial barriers are common in rivers due to the two-dimensional nature of river networks: aquatic organisms cannot circumvent in-river barriers. Barriers in river networks include waterfalls, logjams, or...

Phylogeny and biogeography of Acaena (Rosaceae) and its relatives: Evidence of multiple long-distance dispersal events across the globe

Javier Jauregui Lazo & Daniel Potter
Acaena Mutis ex L. (Rosaceae) is the most complex and ecologically variable genus in the subtribe Sanguisorbinae. Although it has been the subject of several taxonomic treatments, the largest phylogenetic analysis to date only sampled a small fraction of the total global diversity (five to seven out of 45 to 50 species). This study included most of the species to elucidate the phylogenetic relationships of Acaena and biogeographic patterns in Sanguisorbinae. Phylogenetic analyses of non-coding...

Data from: Predators can influence the host-parasite dynamics of their prey via non-consumptive effects

Nicolette Zukowski, Devin Kirk, Kiran Wadhawan, Dylan Shea, Denon Start & Martin Krkosek
Ecological communities are partly structured by indirect interactions, where one species can indirectly affect another by altering its interactions with a third species. In the absence of direct predation, non-consumptive effects of predators on prey have important implications for subsequent community interactions. To better understand these interactions, we used a Daphnia-parasite-predator cue system to evaluate if predation risk affects Daphnia responses to a parasite. We investigated the effects of predator cues on two aspects of...

Data from: Indirect genetic control of migration in a salmonid fish

Suzanne Kelson, Stephanie Carlson & Michael Miller
The paper titled "Indirect genetic control of migration in a salmonid fish" examines the genetic architecture of migration in a partially migratory salmonid fish, Oncorhynchus mykiss. We assess the shared genetic basis between early life growth and migration, and find a shared allelic basis on the Omy05 region of the genome. We then test if early life growth differs among resident/migratory genotype juvenile fish in streams in the South Fork Eel River watershed, in Northern...

Long-term evidence shows crop-rotation diversification increases agricultural resilience to adverse growing conditions in North America

A grand challenge facing humanity is how to produce food for a growing population in the face of a changing climate and environmental degradation. Though empirical evidence remains sparse, management strategies that increase environmental sustainability, like increasing agroecosystem diversity through crop rotations, may also increase resilience to weather extremes without sacrificing yields. We used multilevel regression analyses of long-term crop yield datasets across a continental precipitation gradient to assess how temporal crop diversification affects maize...
