Data from: Age-at-injury influences the glial response to traumatic brain injury in the cortex of male juvenile rats

Rachel Rowe, Tabitha Green, Sean Murphy & J. Bryce Ortiz
Glia influence neuronal development and aging. Few translational studies have examined how age at injury affects the glial response to traumatic brain injury (TBI). We hypothesized that rats injured before sexual maturity would exhibit a greater glial response, that persists into early adulthood, compared to rats injured near the onset of sexual maturity. Postnatal day (PND)17 and PND35 rats received midline fluid percussion injury or sham surgery. In three cortical regions (peri-injury, S1BF, perirhinal), we...

Drivers of global variation in land ownership - dataset

Patrick Kavanagh, Michael Gavin, Hannah Haynie, Geoff Kushnick, Bruno Vilela, Ty Tuff, Claire Bowern, Bobbi Low, Carol Ember, Kathryn Kirby & Carlos Botero
Land ownership shapes natural resource management and social–ecological resilience, but the factors determining ownership norms in human societies remain unclear. Here we conduct a global empirical test of long‐standing theories from ecology, economics and anthropology regarding potential drivers of land ownership and territoriality. Prior theory suggests that resource defensibility, subsistence strategies, population pressure, political complexity and cultural transmission mechanisms may all influence land ownership. We applied multi‐model inference procedures based on logistic regression to cultural...

Overlooked costs of coloniality: Mislaid eggs and the double Incubation of separate nests

Amanda Hund
The evolution of colonial breeding remains an outstanding question in evolutionary biology, in part due to our limited understanding of the costs and benefits of group living. We document 85 cases of Barn Swallows Hirundo rustica erythrogaster laying, and subsequently abandoning, eggs in empty, unclaimed nests located adjacent to active nests during a six-year study. The frequency of this behavior was positively correlated with total available nests, a metric that increases with colony size. In...

Data: Sex-specific effects of capital resources on reproductive timing and success in red squirrels

Jessica Haines, David Delaney, Andrea Wishart, Andrew McAdam, David Coltman, Jeffrey Lane, Ben Dantzer & Stan Boutin
Reproduction is an energetically expensive activity for both sexes. However, if males and females differ in their annual timing of reproduction, such that peak investment for one sex occurs during a more resource-limited period, there is an opportunity for sex-specific selection to act on the acquisition of energetic resources. Both male and female North American red squirrels (Tamiasciurus hudsonicus) cache conifer cones, although males typically have larger caches than females. Peak energetic investment in reproduction...

Data from: Microglia are necessary to regulate sleep after an immune challenge

Rachel Rowe & Tabitha Green
Microglia play a critical role in the neuroimmune response, but little is known about the role of microglia in sleep following an inflammatory trigger. Nevertheless, decades of research have been predicated on the assumption that an inflammatory trigger increases sleep through microglial activation. We hypothesized that mice (n = 30) with depleted microglia would sleep less following administration of lipopolysaccharide (LPS) to induce inflammation. Brains were collected and microglial morphology was assessed using quantitative skeletal...

Dataset associated with: The ERM-1 membrane-binding domain directs erm-1 mRNA localization to the plasma membrane in the C. elegans embryo

Lindsay Winkenbach, Dylan Parker, Robert Williams & Erin Osborne Nishimura
mRNA localization and transport are integral in regulating gene expression. In Caenorhabditis elegans' embryos, the maternally inherited mRNA erm-1 (Ezrin/Radixin/Moesin) becomes concentrated in anterior blastomeres. erm-1 mRNA localizes within those blastomeres to the plasma membrane where the essential ERM-1 protein, a membrane-actin linker, is also found. We demonstrate that the localization of erm-1 mRNA to the plasma membrane is translation dependent and requires its encoded N-terminal, membrane-binding (FERM) domain. By perturbing translation through multiple methods,...

Data from: A migratory divide spanning two continents is associated with genomic and ecological divergence

Sheela Turbek, Drew Schield, Elizabeth Scordato, Andrea Contina, Xin-Wei Da, Yang Liu, Yu Liu, Emilio Pagani-Núñez, Qing-Miao Ren, Chris Smith, Craig Stricker, Michael Wunder, David Zonana & Rebecca Safran
Migratory divides are contact zones between breeding populations with divergent migratory strategies during the non-breeding season. These locations provide an opportunity to evaluate the role of seasonal migration in the maintenance of reproductive isolation, particularly the relationship between population structure and features associated with distinct migratory strategies. We combine light-level geolocators, genomic sequencing, and stable isotopes to investigate the timing of migration and migratory routes of individuals breeding on either side of a migratory divide...

Data from: Decoding the dynamics of dental distributions: insights from shark demography and dispersal

Sora Kim, Justin Yeakel, Juergen Kriwet, Meghan Balk, Jaelyn Eberle, Sarah Zeichner & Dina Fieman
Shark teeth are the most abundant vertebrate fossil, and because tooth size generally correlates with body size, their accumulations document the size structure of populations. Understanding how ecological and environmental processes influence size structure, and how this extends to influence these dental distributions, may offer a window into the ecological and environmental dynamics of past and present shark populations. Here we examine the dental distributions of sand tigers, including extant Carcharias taurus and extinct Striatolamia...

Data from: Convergent evolution of disordered lipidic structural color in the fruits of Lantana strigocamara (syn. L. camara hybrid cultivar)

Miranda Sinnott-Armstrong, Yu Ogawa, Gea Van De Kerkhof, Silvia Vignolini & Stacey Smith
Research conducted: The majority of plant colors are produced by anthocyanin and carotenoid pigments, but coloration obtained by nanostructured materials (i.e., structural colors) is increasingly reported in plants. Here, we identify a multilayer photonic structure in the fruits of Lantana strigocamara and compare it to a previously described origin in Viburnum tinus. Methods: We used a combination of transmission electron microscopy, serial EM tomography, scanning force microscopy, and optical simulations to characterize the photonic structure...

Black capped and mountain chickadee nestling fecal samples

Kathryn Grabenstein
Urban and suburban ecosystems are growing in size and number as the human population continues to increase. Not all cities are built the same, however, and it is still unclear how resident organisms are faring in increasingly urban habitats and whether cities are ecological sinks. To investigate how urbanization is affecting breeding success in insectivorous birds, we studied two species of chickadee, the black-capped and mountain chickadee[KG1] , along an urban-rural gradient in Boulder County,...

Black-capped and mountain chickadee range-wide condition

Kathryn Grabenstein, Scott Taylor, Ken Otter & Theresa Burg
Both abiotic and biotic drivers influence species distributions. Abiotic drivers, such as climate, have received considerable attention, even though biotic drivers, such as hybridization, often interact with abiotic drivers. We sought to explore the (1) costs of co-occurrence for ecologically similar species that hybridize and (2) associations between ecological factors and condition to understand how abiotic and biotic factors influence species distributions. For two closely related and ecologically similar songbirds, black-capped and mountain chickadees, we...

Numerical model simulating the sea ice and ocean conditions in the Amundsen Sea over the period Jan. 1, 2006 to Dec. 31, 2013

Pierre St-Laurent, Eileen E. Hofmann, Robert M. Sherrell, Sharon E. Stammerjohn, Patricia L. Yager, Mathew Biddle & Amber D. York
Numerous coastal polynyas fringe the Antarctic continent and strongly influence the productivity of Antarctic shelf systems. Of the 46 Antarctic coastal polynyas documented in a recent study, the Amundsen Sea Polynya (ASP) stands out as having the highest net primary production per unit area. Incubation experiments suggest that this productivity is partly controlled by the availability of dissolved iron (dFe). As a first step toward understanding the iron supply of the ASP, we introduce four...

Data from: Comparisons of quantitative approaches for assessing microglial morphology reveal inconsistencies, ecological fallacy, and a need for standardization

Rachel Rowe, Tabitha Green & Sean Murphy
Microglia morphology is used as a measure of neuroinflammation and pathology, but different methods to quantify microglia morphology are frequently employed across neuroscience. For reliable inference, it is critical that microglial morphology is accurately quantified and that results can be easily interpreted and compared across studies. We applied five of the most commonly used ImageJ-based methods for quantifying the microglial morphological response to a stimulus to identical photomicrographs and isolated microglial cells, which allowed for...
