Measurements from the Fire Influence on Regional and Global Environments Experiment (FIREX) Fire Lab Mini Chamber Experiment

Christopher Cappa, Christopher Lim, David Hagan & Jesse Kroll
All experiments were conducted during the Fire Influence on Regional to Global Environments Experiment (FIREX) lab study, which took place at the Missoula Fire Sciences Lab in Missoula, MT, USA during November, 2016. Experiments focused on refining our understanding of emissions and short timescale processing. The focus was on measuring fuels or combustion conditions that are characteristic of the western U.S. that may be under-sampled by the fire research community. Numerous types of biomass were...

Root and shoot variation in relation to potential intermittent drought adaptation of Mesoamerican wild common bean (Phaseolus vulgaris L.)

Paul Gepts, Jorge Carlos Berny Mier Y Teran, Enéas R Konzen, Viviana Medina, Antonia Palkovic, Andrea Ariani, Siu M. Tsai & Matthew E. Gilbert
• Background Wild crop relatives have been potentially subjected to stresses on an evolutionary time scale prior to domestication. Among these stresses, drought is one of the main factors limiting crop productivity and its impact is likely to increase under current scenarios of global climate change. We sought to determine to what extent wild common bean (Phaseolus vulgaris) exhibited adaptation to drought stress, whether this potential adaptation is dependent on the climatic conditions of the...

Channel types predictions for the Sacramento River basin

Hervé Guillon, Colin F. Byrne, Belize Arela Albin Lane, Samuel Sandoval Solis & Gregory Brian Pasternack
Hydrologic and geomorphic classifications have gained traction in response to the increasing need for basin-wide water resources management. Regardless of the selected classification scheme, an open scientific challenge is how to extend information from limited field sites to classify tens of thousands to millions of channel reaches across a basin. To address this spatial scaling challenge, we leveraged machine learning to predict reach-scale geomorphic channel types using publicly available geospatial data.

Data from: Measuring behavior patterns and evaluating time sampling methodology to characterize brush use in weaned beef cattle

Kelsey Horvath, Rachel Toaff-Rosenstein, Cassandra Tucker & Emily Miller-Cushon
With growing interest in provision of brushes to cattle, and implications of brush use for behavioral development and welfare, there is a need to validate methodology for quantifying grooming behavior. Our objectives were to characterize patterns of brush use, including bouts, diurnal activity, and individual variability over 24-h periods and to validate time sampling methodologies to characterize these traits, including instantaneous recording at various time intervals and continuous recording for subsets of the day. Data...

Data from: Forests do not limit bumble bee foraging movements in a montane meadow complex

John Mola, Michael Miller, Sean O'Rourke & Neal Williams
Understanding the roles of habitat fragmentation and resource availability in shaping animal movement are integral for promoting species persistence and conservation. For insects like bumble bees, their movement patterns affect the survival and reproductive potential of their colonies as well as the pollen flow of plant species. However, our understanding of their mobility or the impact of putative barriers in natural environments is limited due to the technical difficulties of studying wild populations. We used...

Data from: Frequency-dependent fitness and reproductive dynamics contribute to habitat segregation in sympatric Jewelflowers

Kyle Christie & Sharon Y. Strauss
Coexistence results from a complex suite of past and contemporary processes including biogeographic history, adaptation, ecological interactions, and reproductive dynamics. Here we explore drivers of local micro-parapatry in which two closely related and reproductively isolated Streptanthus species (Jewelflower, Brassicaceae) inhabit continuous or adjacent habitat patches and occur within seed dispersal range, yet rarely overlap in fine-scale distribution. We find some evidence for abiotic niche partitioning and local adaptation, however differential survival across habitats cannot fully...

Data from: Comparisons of Late Ordovician ecosystem dynamics before and after the Richmondian Invasion reveal consequences of invasive species in benthic marine paleocommunities

Hannah Kempf, Ian Castro, Ashley Dineen, Carrie Tyler & Peter Roopnarine
A thorough understanding of how communities respond to extreme changes, such as biotic invasions, is essential to manage ecosystems today. Here we constructed fossil food webs to identify changes in Late Ordovician (Katian) shallow marine paleocommunity structure and functioning before and after the Richmondian Invasion, a well-documented ancient invasion. Food webs were compared using descriptive metrics and Cascading Extinction on Graphs models. Richness at intermediate trophic levels was underrepresented when using only data from the...

Data from: Fostering the use of zero and near zero emission vehicles in freight operations

Miguel Jaller, Leticia Pineda, Yasar Gueldas, Farzad Alemi & Irem Otay
California has put forward a number of goals to improve freight efficiency through the introduction and use of zero and near-zero emission vehicles. However, the technical and operational characteristics, market readiness, and other factors related to these technologies can be very different. Therefore, the most appropriate option for different uses (e.g., last mile, long-haul distribution) and users’ preferences is not necessarily clear. This study focused on analyzing the factors to foster the adoption of zero...

Bayesian total-evidence inference resolves the position of the ant genus Phaulomyrma (Hymenoptera, Formicidae)

Zachary Griebenow
Although molecular data have proven indispensable in confidently resolving the phylogeny of many clades across the tree of life, these data may be inaccessible for certain taxa. The resolution of taxonomy in the ant subfamily Leptanillinae is made problematic by the absence of DNA sequence data for leptanilline taxa that are known only from male specimens, including the monotypic genus Phaulomyrma Wheeler & Wheeler. Focusing upon the considerable diversity of undescribed male leptanilline morphospecies, the...
