Plant-soil feedbacks (PSFs) have been shown to strongly affect plant performance under controlled conditions, and PSFs are thought to have far reaching consequences for plant population dynamics and the structuring of plant communities. However, thus far the relationship between PSF and plant species abundance in the field is not consistent. Here, we synthesize PSF experiments from tropical forests to semiarid grasslands, and test for a positive relationship between plant abundance in the field and PSFs...

Footprints of local adaptation span hundreds of linked genes in the Atlantic silverside genome

Aryn Wilder, Stephen Palumbi, David Conover & Nina Overgaard Therkildsen
The study of local adaptation in the presence of ongoing gene flow is the study of natural selection in action, revealing the functional genetic diversity most relevant to contemporary pressures. In addition to individual genes, genome-wide architecture can itself evolve to enable adaptation. Distributed across a steep thermal gradient along the east coast of North America, Atlantic silversides (Menidia menidia) exhibit an extraordinary degree of local adaptation in a suite of traits, and the capacity...

Chromonomer: a tool set for repairing and enhancing assembled genomes through integration of genetic maps and conserved synteny

Julian Catchen, Angel Amores & Susan Bassham
The pace of the sequencing and computational assembly of novel reference genomes is accelerating. Though DNA sequencing technologies and assembly software tools continue to improve, biological features of genomes such as repetitive sequence as well as molecular artifacts that often accompany sequencing library preparation can lead to fragmented or chimeric assemblies. If left uncorrected, defects like these trammel progress on understanding genome structure and function, or worse, positively mislead this research. Fortunately, integration of additional,...

Latitudinal gradients in population growth do not reflect demographic responses to climate

Megan Peterson, Graham Bailes, Lauren Hendricks, Laurel Pfeifer-Meister, Paul Reed, Scott Bridgham, Bart Johnson, Robert Shriver, Ellen Waddle, Hannah Wroton, Daniel Doak, Bitty Roy & William Morris
Spatial gradients in population growth, such as across latitudinal or elevational gradients, are often assumed to primarily be driven by variation in climate, and are frequently used to infer species’ responses to climate change. Here, we use a novel demographic, mixed model approach to dissect the contributions of climate variables vs. other latitudinal or local site effects on spatiotemporal variation in population performance in three perennial bunchgrasses. For all three species, we find that performance...

Data from: Phylogeographic estimation and simulation of global diffusive dispersal

Stilianos Louca
The analysis of time-resolved phylogenies (timetrees) and geographic location data allows estimation of dispersal rates, for example for invasive species and infectious diseases. Many estimation methods are based on the Brownian Motion model for diffusive dispersal on a 2-dimensional plane, however the accuracy of these methods deteriorates substantially when dispersal occurs at global scales because Spherical Brownian Motion (SBM) differs from planar Brownian Motion. No statistical method exists for estimating SBM diffusion coefficients from a...

Dynamics of gaze control during prey capture in freely moving mice

Angie Michaiel, Elliott Abe & Cristopher Niell
Most studies of visual processing are conducted under head- and gaze-restricted conditions. While this provides experimental control, it radically limits the natural exploration of the visual world which is typically achieved through directed eye, head, and body movements. As such, less is known about how animals naturally sample the external visual world to acquire relevant visual information in natural contexts. To determine how mice target their gaze and sample the visual world during natural behavior,...

Climate manipulations differentially affect plant population dynamics within versus beyond northern range limits

Paul Reed, Megan Peterson, Laurel Pfeifer-Meister, William Morris, Daniel Doak, Bitty Roy, Bart Johnson, Graham Bailes & Aaron Nelson
Predicting species’ range shifts under future climate is a central goal of conservation ecology. Studying populations within and beyond multiple species’ current ranges can help identify whether demographic responses to climate change exhibit directionality, indicative of range shifts, and whether responses are uniform across a suite of species. We quantified the demographic responses of six native perennial prairie species planted within and, for two species, beyond their northern range limits to a three-year experimental manipulation...

Archaeological mitogenomes illuminate the historical ecology of sea otters (Enhydra lutris) and the viability of reintroduction

Hannah Wellman, Rita Austin, Nihan Dagtas, Madonna Moss, Torben Rick & Courtney Hofman
Genetic analyses are an important contribution to wildlife reintroductions, particularly in the modern context of extirpations and ecological destruction. To address the complex historical ecology of the sea otter (Enhydra lutris) and its failed 1970s reintroduction to coastal Oregon, we compared mitochondrial genomes of pre-extirpation Oregon sea otters to extant and historical populations across the range. We sequenced the first complete ancient mitogenomes from archaeological Oregon sea otter dentine and historical sea otter dental calculus....

Popocatepetl ash charge as function of humidity and temperature

Joshua Méndez Harper
Here, we provide the absolute charge collected by volcanic ash (Popocatepetl) in the range of 250-500 microns through frictional interactions as a function of relative humidity (RH) and temperature. The range of RH is 0-50% (at 25 C) and the range of temperature is -20-40 C (at 30 % RH). Particles were charged triboelectrically and the charge was measuirend on individual particles using a miniature Farday cup. All values are reported in pico-Coulombs.

Data from: Local adaptation to herbivory within tropical tree species along a rainfall gradient

Andrew Muehleisen, Bettina Engelbrecht, F. Andrew Jones, Eric Manzané-Pinzón & Liza Comita
In tropical forests, insect herbivores exert significant pressure on plant populations. Adaptation to such pressure is hypothesized to be a driver of high tropical diversity, but direct evidence for local adaptation to herbivory in tropical forests is sparse. At the same time, herbivore pressure has been hypothesized to increase with rainfall in the tropics, which could lead to differences among sites in the degree of local adaptation. To assess the presence of local adaptation and...

Data from: Cryptic patterns of speciation in cryptic primates: microendemic mouse lemurs and the multispecies coalescent

Jelmer Poelstra, Jordi Salmona, George Tiley, Dominik Schüßler, Marina Blanco, Jean Andriambeloson, Olivier Bouchez, C. Ryan Campbell, Paul Etter, Amaia Iribar-Pelozuelo, Paul Hohenlohe, Kelsie Hunnicutt, Eric Johnson, Peter Kappeler, Peter Larsen, Sophie Manzi, Jose Ralison, Blanchard Randrianambinina, Rodin Rasoloarison, David Rasolofoson, Amanda Stahlke, David Weisrock, Rachel Williams, Lounes Chikhi, Ed Louis … & Anne Yoder
Species delimitation is ever more critical for assessing biodiversity in threatened regions of the world, especially when undescribed lineages may be at risk from habitat loss. Mouse lemurs (Microcebus) are an example of a rapid radiation of morphologically cryptic species that are distributed throughout Madagascar in its rapidly vanishing forested habitats. Here, we focus on two pairs of sister lineages that occur in a region in northeastern Madagascar that shows high levels of microendemism. We...

Public opinion about management strategies for a low-profile Species across multiple jurisdictions: whitebark pine in the northern Rockies

Elizabeth Shanahan, Eric Raile, Helen Naughton, Michael Wallner & Kendall Houghton
1. As public land managers seek to adopt and implement conservation measures aimed at reversing or slowing the negative effects of climate change, they are looking to understand public opinion regarding different management strategies. 2. This study explores drivers of attitudes toward different management strategies (i.e., no management, protection, and restoration) for a low-profile but keystone tree species, the whitebark pine (Pinus albicaulis), in the Greater Yellowstone Ecosystem. Since the whitebark pine species has a...
