Data from: Female American black bears do not alter space use or movements to reduce infanticide risk

D. Cody Norton, Jerrold L. Belant, John G. Bruggink, Dean E. Beyer, Nathan J. Svoboda & Tyler R. Petroelje
Infanticide occurs in a variety of animal species and infanticide risk has large implications for the evolution of behavior. Further, the sex hypothesis of sexual segregation predicts that for species in which infanticide occurs, females with dependent young will avoid males to reduce risk of sexually-selected infanticide. Infanticide risk-avoidance behavior has been studied primarily in social species, but also occurs in some solitary species. We used generalized linear mixed models to determine if space use...

Data from: Target gene enrichment in the cyclophyllidean cestodes, the most diverse group of tapeworms

Hao Yuan, Jiamei Jiang, F. Agustín Jiménez, Eric P. Hoberg, Joseph A. Cook, Kurt E. Galbreath & Chenhong Li
The Cyclophyllidea is the most diverse order of tapeworms, encompassing species that infect all classes of terrestrial tetrapods including humans and domesticated animals. Available phylogenetic reconstructions based either on morphology or molecular data lack the resolution to allow scientists to either propose a solid taxonomy or infer evolutionary associations. Molecular markers available for the Cyclophyllidea mostly include ribosomal DNA and mitochondrial loci. In this study, we identified 3,641 single-copy nuclear coding loci by comparing the...

Data from: Environmental context and contaminant biotransport by Pacific salmon interact to mediate the bioaccumulation of contaminants by stream-resident fish

1.The extent to which environmental context mediates the bioaccumulation of biotransported contaminants by stream-resident organisms is poorly understood. For example, it is unclear the extent to which contaminant type, instream characteristics, or resident fish identity interact to influence the uptake of contaminants deposited by Pacific salmon (Oncorhynchus spp.) during their spawning runs. 2.To address this uncertainty, we sampled four stream-resident fish species from 13 watersheds of the Laurentian Great Lakes in locations with and without...

Data from: Multi-scale quantification of tissue behavior during amniote embryo axis elongation

Bertrand Benazeraf, Mathias Beaupeux, Martin Tcherknookov, Allison Wallingford, Tasha Salisbury, Amelia Shirtz, Andrew Shirtz, David Huss, Olivier Pourquie, Paul Francois & Rusty Lansford
Embryonic axis elongation is a complex multi-tissue morphogenetic process responsible for the formation of the posterior part of the amniote body. How movements and growth are coordinated between the different posterior tissues (e.g. neural tube, axial and paraxial mesoderm, lateral plate, ectoderm, endoderm) to drive axis morphogenesis remain largely unknown. Here, we use quail embryos to quantify cell behavior and tissue movements during elongation. We quantify the tissue-specific contribution to axis elongation by using 3D...

Regional climates shape the biogeographic history of a broadly distributed freshwater crab species complex

Boyang Shi, Da Pan, Yufang Sun, Hongying Sun, Neil Cumberlidge, Xiulin Lv & Xiaorui Liu
Aim: The evolutionary importance of paleoclimate regimes has been noted in biogeographic studies. However, little is known about how paleoclimate differences shaped the biogeographic pattern and diversification history of the freshwater fauna in important zoogeographical boundary regions. Here, we aim to investigate how past regional climatic differences have shaped the biogeographic history of the inland aquatic fauna in China using an endemic freshwater crab species complex found on both sides of the Qinling Mountains–Huaihe River...

Taxon pulse dynamics, episodic dispersal, and host colonization across Beringia drive diversification of a holarctic tapeworm assemblage

Genevieve Haas, Eric Hoberg, Joseph Cook, Heikki Henttonen, Arseny Makarikov, Sarah Gallagher, Nikolai Dokuchaev & Kurt Galbreath
Aim: We test the predictions of the Stockholm Paradigm, a synthesis of eco-evolutionary theory explaining the nature of faunal assembly, host range and parasite diversification. Faunal diversification and assembly, manifested in patterns of host colonization, co-adaptation and parasite speciation, is predicted to emerge as a consequence of alternating episodes of ecological disruption and stability. Specifically, for a diverse cestode genus (Arostrilepis), we evaluate the number and direction of Pleistocene dispersal events across Beringia, the number...

Leveraging genomics to understand threats to migratory birds

Brenda Larison, Alec R. Lindsay, Christen Bossu, Michael D. Sorenson, Joseph D. Kaplan, David C. Evers, James Paruk, Jeffrey M. DaCosta, Thomas B. Smith & Kristen Ruegg
Understanding of how risk factors affect populations across their annual cycle is a major challenge for conserving migratory birds. For example, disease outbreaks may happen on the breeding grounds, the wintering grounds, or during migration, and are expected to accelerate under climate change. The ability to identify the geographic origins of individuals impacted, especially outside of breeding areas, might make it possible to predict demographic trends and inform conservation decision making. However, such an effort...
