Primates have adapted to numerous environments and lifestyles but very few species are native to high elevations. Here, we investigated high-altitude adaptations in the gelada (Theropithecus gelada), a monkey endemic to the Ethiopian Plateau. We examined genome-wide variation in conjunction with measurements of haematological and morphological traits. Our new gelada reference genome is highly intact and assembled at chromosome-length levels. Unexpectedly, we identified a chromosomal polymorphism in geladas that could potentially contribute to reproductive barriers...

The evolution of multi-gene families and metabolic pathways in the evening primroses (Oenothera: Onagraceae): a comparative transcriptomics approach

Eunice Kariñho-Betancourt, Dave Carlson, Jesse Hollister, Axel Fischer, Stephan Greiner & Marc Johnson
The plant genus Oenothera has played an important role in the study of genome evolution and plant defense and reproduction. Here, we built on the 1kp transcriptomic dataset and developed a molecular resource of 63 transcriptomes and present a large-scale comparative study across 29 Oenothera species. We produced 2.3 million transcripts and 25.4 Mb of total length assembly per individual. We used this transcriptome resource to examine genome-wide evolutionary patterns and functional diversification by searching...

The biogeography of community assembly: latitude and predation drive variation in community trait distribution in a guild of epifaunal crustaceans

Collin Gross, Collin Gross, J Duffy, Kevin Hovel, Melissa Kardish, Pamela Reynolds, Christoffer Boström, Katharyn Boyer, Mathiew Cusson, Johan Eklöf, Aschwin Engelen, Klemens Eriksson, Joel Fodrie, John Griffin, Clara Hereu, Masakazu Hori, A Randall Hughes, Mikhail Ivanov, Pablo Jorgensen, Claudia Kruschel, Kun-Seop Lee, Jonathan Lefcheck, Karen McGlathery, Per-Olav Moksnes, Masahiro Nakaoka … & Jay Stachowicz
While considerable evidence exists of biogeographic patterns in the intensity of species interactions, the influence of these patterns on variation in community structure is less clear. Using a model selection approach on measures of trait dispersion in crustaceans associated with eelgrass (Zostera marina) spanning 30º of latitude in two oceans, we found that dispersion strongly increased with increasing predation and decreasing latitude. Ocean and epiphyte load appeared as secondary predictors; Pacific communities were more overdispersed...

Supplemental dataset from: Initial acoustoelastic measurements in olivine: Investigating the effect of stress on P- and S-wave velocities

Taryn Traylor, Pamela Burnley & Matthew Whitaker
It is well known that elasticity is a key physical property in the determination of the structure and composition of the Earth and provides critical information for the interpretation of seismic data. This study investigates the stress-induced variation in elastic wave velocities, known as the acoustoelastic effect, in San Carlos olivine. A recently developed experimental ultrasonic acoustic system, the Directly Integrated Acoustic System Combined with Pressure Experiments (DIASCoPE), was used with the D-DIA multi-anvil apparatus...

EcoPhyloMapper: an R package for integrating geographic ranges, phylogeny, and morphology

Pascal Title, Donald Swiderski & Miriam Zelditch
1. Spatial patterns of species richness, phylogenetic and morphological diversity are key to answering many questions in ecology and evolution. Across spatial scales, geographic and environmental features, as well as evolutionary history and phenotypic traits, are thought to play roles in shaping both local species communities and regional assemblages. By examining these geographic patterns, it is possible to infer how different axes of biodiversity influence one another, and how their interaction with abiotic factors has...

Data from: Integrating 3D models with morphometric measurements to improve volumetric estimates in marine mammals

Nathan Hirtle, Julia Stepanuk, Eleanor Heywood, Fredrik Christiansen & Lesley Thorne
1. Studies of body condition are key to understanding the health, bioenergetics, and ecological roles of marine mammals. Due to challenges in studying marine mammals at sea, body condition is often approximated using metrics representing the size of the dorsal surface visible from aerial imagery, but quantifying variability in body volume would enable a more holistic understanding of bioenergetics. Further, the number and location of measurements needed to accurately quantify body condition has received little...

Evolutionary determinants of non-seasonal breeding in wild chacma baboons

Jules Dezeure, Lugdiwine Burtschell, Alice Baniel, Alecia J. Carter, Bernard Godelle, Cowlishaw Guy & Huchard Elise
Animal reproductive phenology varies from strongly seasonal to non-seasonal, sometimes among closely related or sympatric species. While the extent of reproductive seasonality is often attributed to environmental seasonality, this fails to explain many cases of non-seasonal breeding in seasonal environments. We investigated the evolutionary determinants of non-seasonal breeding in a wild primate, the chacma baboon (Papio ursinus), living in a seasonal environment with high climatic unpredictability. We tested three hypotheses proposing that non-seasonal breeding has...

Using GBIF to Demonstrate Colonial Legacies on Biodiversity Data

Ryan S. Mohammed, Melissa Kemp, Michelle J. LeFebvre, Alexis M. Mychajliw, Grace Turner, Kelly Fowler, Michael Pateman, Maria A. Nieves-Colón, Lanya Fanovich, Siobhan B. Cooke, Liliana M. Dávalos, Scott M. Fitzpatrick, Christina M. Giovas, Myles Stokowski & Ashley A. Wrean
Biologists recognize the Caribbean archipelago as a biodiversity hotspot and employ it for their research as a “natural laboratory”, but do not always appreciate that these ecosystems are in fact palimpsests shaped by multiple human cultures over millennia. We discuss two case studies of the Caribbean’s fragmented natural history collections, the effects of differing legislation and governance by the region’s multiple nation states. We use digital natural history specimen data from GBIF to demonstrate how...

A role for myosin II cluster and membrane energy in cortex rupture for Dictyostelium discoideum cells

Emmanuel Asante-Asamani, Daniel Grange, Devarshi Rawal, Zully Santiago, John Loustau & Derrick Brazill
Blebs, pressure driven protrusions of the cell membrane, facilitate the movement of eukaryotic cells such as the soil amoeba Dictyostelium discoideum, white blood cells and cancer cells. Blebs initiate when the cell membrane separates from the underlying cortex. A local rupture of the cortex, has been suggested as a mechanism by which blebs are initiated. However, much clarity is still needed about how cells inherently regulate rupture of the cortex in locations where blebs are...

Structure-from-motion-generated imagery, nest location coordinates and counts for Adelie, chinstrap, gentoo and macaroni penguins on the South Sandwich Islands, from December to February, 2019-2020.

Tom Hart, Sarah Manthorpe, Gemma Clucas & Heather Lynch
This dataset contains penguin survey data and imagery from unmanned aerial vehicles (UAV) across the South Sandwich Islands, from December 2019 to February 2020. It comprises orthotiff images (orthotiffs) and digital elevation models (DEMS) of surveyed sites, geographic penguin colony outlines, nest coordinates for individual species, mixed species' sub-colonies and groups where species-level identification was not possible. Finally, it also includes the total count for these different categories for each individual site, alongside an estimate...

Recombination experiments with inversion heterozygotes

Spencer Koury
Recombination suppression in chromosomal inversion heterozygotes is a well-known but poorly understood phenomenon. Surprisingly, recombination suppression extends far outside of inverted regions where there are no intrinsic barriers to normal chromosome pairing, synapsis, double-strand break formation, or recovery of crossover products. The interference hypothesis of recombination suppression proposes heterozygous inversion breakpoints possess chiasma-like properties such that recombination suppression extends from these breakpoints in a process analogous to crossover interference. This hypothesis is qualitatively consistent with...

Why the long teeth? Morphometric analysis suggests different selective pressures on functional occlusal traits in Plio-Pleistocene African suids

Deming Yang, Asli Pisano, Joan Kolasa, Tea Jashashvili, Job Kibii, Ana Gomez Cano, Laurent Viriot, Frederick Grine & Antoine Souron
Neogene and Pleistocene African suids displayed convergent evolutionary trends in the third molar (M3) morphology, with increasingly elongated and higher crowns through time. While these features can prevent premature loss of masticatory functionality and potentially increase long-term reproductive success, changes in dental occlusal traits such as enamel complexity and thickness can also improve chewing efficiency and increase short-term energetic return. While both long-term and short-term benefits can contribute to the thriving of a lineage, the...
