Michael Anderson, Mariska Te Beest, Colleen Begg, Keith Begg, Aurelie Bonin, Lackson Chama, Simon Chamaillé-Jammes, Eric Coissac, Joris Cromsigt, Margaret Demmel, Jason Donaldson, Jennifer Guyton, Christina Hansen, Christopher Imakando, Azwad Iqbal, Davis Kalima, Graham Kerley, Samson Kurukura, Marietjie Landman, Ryan Long, Isaack Munuo, Ciara Nutter … & Tyler Kartzinel
Ecological niche differences are necessary for stable species coexistence but are often difficult to discern. Models of dietary niche differentiation in large mammalian herbivores invoke the quality, quantity, and spatiotemporal distribution of plant tissues and growth-forms but are agnostic towards food-plant species identity. Empirical support for these models is variable, suggesting that additional mechanisms of resource partitioning may be important in sustaining large-herbivore diversity in African savannas. We used DNA metabarcoding to conduct a taxonomically...

Data from: High-resolution estimates of crossover and noncrossover recombination from a captive baboon colony

Jeffrey Wall, Jacqueline Robinson & Laura Cox
Homologous recombination has been extensively studied in humans and a handful of model organisms. Much less is known about recombination in other species, including non-human primates. Here we present a study of crossovers and non-crossover (NCO) recombination in olive baboons (Papio anubis) from two pedigrees containing a total of 20 paternal and 17 maternal meioses, and compare these results to linkage disequlibrium (LD) based recombination estimates from 36 unrelated olive baboons. We demonstrate how crossovers,...

Fire, grazers and browsers interact with grass competition to determine tree establishment in an African savanna

Jason Donaldson, Ricardo Holdo, T. Michael Anderson & Jeremia Sarakikya
In savanna ecosystems, fire and herbivory alter the competitive relationship between trees and grasses. Mechanistically, grazing herbivores favor trees by removing grass, which reduces tree-grass competition and limits fire. Conversely, browsing herbivores consume trees and limit their recovery from fire. Herbivore feeding decisions are in turn shaped by risk-resource trade-offs that potentially determine the spatial patterns of herbivory. Identifying the dominant mechanistic pathways by which fire and herbivores control tree cover remains challenging, but is...

Data from: First-year Acacia seedlings are anisohydric ‘water-spenders’ but differ in their rates of water use

Scott Cory
Premise of the study: The first-year tree seedling (FYS) life stage may be a critical demographic bottleneck in semi-arid, seasonally dry ecosystems such as savannas. Given the highly variable water availability and potentially strong FYS-grass competition for water here, FYS water-use strategies may play a crucial role in FYS establishment and, ultimately, tree-grass competition and coexistence. Methods: We examined drought responses in FYS of two tree species that are dominant on opposite ends of an...

Body mass index influence on lap belt position and abdominal injury in frontal motor vehicle crashes

Sydney Schieffer, Casey Costa, Rohin Gawdi, Karan Devane, Isaac N. Ronning, Thomas Hartka, R. Shayn Martin, Bahram Kiani, Anna N. Miller, Fang-Chi Hsu, Joel D. Stitzel & Ashley A. Weaver
As obesity rates climb, it is important to study its effects on motor vehicle safety due to differences in restraint interaction and biomechanics. Previous studies have shown that an abdominal seatbelt sign (referred hereafter as seatbelt sign) sustained from motor vehicle crashes (MVCs) is associated with abdominal trauma when located above the anterior superior iliac spine (ASIS). This study investigates whether placement of the lap belt causing a seatbelt sign is associated with abdominal organ...

Effects of muscle quantity and bone mineral density on injury and outcomes in older adult motor vehicle crash occupants

William Armstrong, Casey Costa, Luis Poveda, Anna N. Miller, Alexander Ambrosini, Fang-Chi Hsu, Bahram Kiani, R. Shayn Martin, Joel D. Stitzel & Ashley A. Weaver
Objectives: Quantify the independent and combined effects of abdominal muscle quantity and lumbar bone mineral density (BMD) on injury risk and in-hospital outcomes in severely injured motor vehicle crash (MVC) occupants ages 50 and older. Methods: Skeletal muscle area measurements of MVC occupants were obtained through semi-automated segmentation of an axial computed tomography (CT) slice at the L3 vertebra. An occupant height-normalized Skeletal Muscle Index (SMI) was calculated - a defining metric of sarcopenia and...

CONUS VPD and soil moisture thresholds for suboptimal vegetation function

Lauren Lowman
The dataset contains minimum and maximum vapor pressure deficit (VPD) and soil moisture parameters that define the range of suboptimal vegetation function (i.e., between uninhibited photosynthesis and complete shutdown). The ranges were estimated using the Dynamic Canopy Biophysical Properties model (DCBP; Lowman & Barros 2018), which consists of a phenology forecasting model based on the growing season index (GSI), which provides a unitless measure of the potential phenologic state of vegetation based on the concurrent...

Phylogenetic divergence and ecophysiological variation in the disjunct Kalmia buxifolia (Sand-myrtle, Ericaceae)

Ellen Quinlan, Katherine Mathews, Beverly Collins & Robert Young
Kalmia buxifolia (sand-myrtle, Ericaceae) is disjunctly distributed across the high-elevation rock outcrops of the southern Appalachians, upper monadnocks and pine savannas of the Carolina Piedmont and Coastal Plain, and the New Jersey Pine Barrens. Here, we sampled plants from each region and reconstructed the phylogeographic history of K. buxifolia to test a rock-outcrop Pleistocene refugium hypothesis, estimate the potential direction(s) and timing of migration, and date divergence from its alpine sister species, K. procumbens. We...

Salomão, Leandro Valle Ferreira, Dário Dantas Do Amaral, Nigel C.A. Pitman, Corine Vriesendorp, Tim R. Baker, Roel Brienen, Marcelo De Jesus Veiga Carim … & Flávia R.C. Costa
Tree diversity and composition in Amazonia are known to be strongly determined by the water supplied by precipitation. Nevertheless, within the same climatic regime, water availability is modulated by local topography and soil characteristics (hereafter referred to as local hydrological conditions), varying from saturated and poorly drained to well-drained and potentially dry areas. While these conditions may be expected to influence species distribution, the impacts of local hydrological conditions on tree diversity and composition remain...

Improving landscape-scale productivity estimates by integrating trait-based models and remotely-sensed foliar-trait and canopy-structural data

Daniel Wieczynski, Sandra Diaz, Sandra Duran, Nikolaos Fyllas, Norma Salinas, Roberta Martin, Alexander Shenkin, Miles Silman, Gregory Asner, Lisa Bentley, Yadvinder Malhi, Brian Enquist & Van Savage
Assessing the impacts of anthropogenic degradation and climate change on global carbon cycling is hindered by a lack of clear, flexible, and easy-to-use productivity models along with scarce trait and productivity data for parameterizing and testing those models. We provide a simple solution: a mechanistic framework (RS-CFM) that combines remotely-sensed foliar-trait and canopy-structural data with trait-based metabolic theory to efficiently map productivity at large spatial scales. We test this framework by quantifying net primary productivity...

Woodpecker drum evolution: an analysis of covariation in elements of a multicomponent acoustic display among and within species

Nicole M Moody, Emma K Vivlamore & Matthew J Fuxjager
Multicomponent signals are found throughout the animal kingdom, but how these elaborate displays evolve and diversify is still unclear. Here, we explore the evolution of the woodpecker drum display. Two components of this territorial, sexually selected signal, drum speed and drum length, are used by territory holders to assess the threat level of an intruding drummer. We explore the coevolution of these display components both among and within species. Among species, we find evidence for...
