Pinniped comparative survival data

Brusa Jamie
Survival rates are a central component of life-history strategies of large vertebrate species. However, comparative studies seldom investigate interspecific variation in survival rates with respect to other life-history traits, especially for males. The lack of such studies could be due to the challenges associated with obtaining reliable datasets, incorporating information on the 0-1 probability scale, or dealing with several types of measurement error in life-history traits, which can be a computationally intensive process that is...

Data from: Mammal-bearing gastric pellets potentially attributable to Troodon formosus at the Cretaceous Egg Mountain locality, Two Medicine Formation, Montana, U.S.A.

William Freimuth, David Varricchio, Alexandria Brannick, Lucas Weaver & Gregory Wilson Mantilla
Fossil gastric pellets (regurgitalites) have distinct taphonomic characteristics that facilitate inferences of behavioural ecology in deep time, despite their rarity in the fossil record. Using the taphonomic patterns of both extant and fossil small mammals from more recent geologic deposits as a guide, we assess the taphonomy of three unusual multi-individual aggregates of mammal skeletons from paleosols at Egg Mountain, a dinosaur nesting locality from the Upper Cretaceous Two Medicine Formation, Montana, USA. One aggregate...

Spatial dynamics of pathogen transmission in communally roosting species: Impacts of changing habitats on bat-virus dynamics

Tamika Lunn, Tamika Lunn, Alison Peel, Hamish McCallum, Peggy Eby, Maureen Kessler, Raina Plowright & Olivier Restif
1. The spatial organisation of populations determines their pathogen dynamics. This is particularly important for communally roosting species, whose aggregations are often driven by the spatial structure of their environment. 2. We develop a spatially explicit model for virus transmission within roosts of Australian tree-dwelling bats (Pteropus spp.), parameterised to reflect Hendra virus. The spatial structure of roosts mirrors three study sites, and viral transmission between groups of bats in trees was modelled as a...

35,000-year record of pollen, charcoal and NPP from Bass Strait, southeast Australia

Matthew Adeleye, Simon Haberle, David McWethy, Simon Connor & Janelle Stevenson
We reconstruct the last glacial vegetation (pollen record), fire (charcoal record) and lake levels (NPP record) for Bass Strait. Results show the Bass Strait area was characterized by Eucalyptus woodland and shrubland vegetation, with high fire activity and lake levels from 35,000 to 29,000 years ago. Grassland expanded at the expense of woodland after this period, with a decline in fire activity and lake levels.

Data in support of: Biomineralization of plastic waste to improve the strength of plastic-reinforced cement mortar

Seth Kane, Abby Thane, Michael Espinal, Kendra Lunday, Hakan Armağan, Adrienne Phillips, Chelsea Heveran & Cecily Ryan
The development of methods to reuse large volumes of plastic waste is essential to curb the environmental impact of plastic pollution. Plastic-reinforced cementitious materials (PRCs), such as plastic-reinforced mortar (PRM), may be potential avenues to productively use large quantities of low-value plastic waste. However, poor bonding between the plastic and cement matrix reduces the strength of PRCs, limiting its viable applications. In this study, calcium carbonate biomineralization techniques were applied to coat plastic waste and...

Differential learning by native versus invasive predators to avoid distasteful cleaning mutualists

Lillian Tuttle, Robert Lamb & Allison Stringer
1. Cleaning symbioses on coral reefs are mutually beneficial interactions between two individuals, in which a ‘cleaner’ removes and eats parasites from the surface of a ‘client’ fish. A suite of behavioural and morphological traits of cleaners signal cooperation with co-evolved species, thus protecting the cleaner from being eaten by otherwise predatory clients. However, it is unclear whether cooperation between cleaners and predatory clients is innate or learned, and therefore whether an introduced predator might...

Resource allocation effects on the timing of reproduction in an avian habitat specialist

Kyle Cutting, Jay Rotella, James Waxe, Aaron O' Harra, Sean Schroff, Lorelle Berkeley, Mark Szczypinski, Andrea Litt & Bok Sowell
Variation in nutrient allocation can influence the timing of breeding and ultimately reproductive output. Time and space constraints might exist, however, if fewer food resources are available to meet the costs of reproduction early during the reproductive season. Here, for the first time, we test whether nutrient allocation strategies for reproduction in a shrub-dependent avian species differs with timing of breeding in different ecoregions: a high-elevation landscape, containing spatially complex vegetation (Rocky Mountains) versus a...

Data from the article: Narrative Risk Communication as a Lingua Franca for Environmental Hazard Preparation

Eric D. Raile, Elizabeth A. Shanahan, Richard C. Ready, Jamie McEvoy, Clemente Izurieta, Ann Marie Reinhold, Geoffrey C. Poole, Nicolas T. Bergmann & Henry King
Incorporating narrative elements into risk communication may encourage preparation for environmental hazards in ways that scientific language alone does not. We integrate narrative theory, narrative persuasion, and risk theories into a Narrative Risk Communication Framework and then assess the effectiveness of character selection as a narrative mechanism in scientific risk communication as compared to conventional science messaging alone. We utilize a survey experiment with residents along the flood-prone Yellowstone River in Montana and analyze the...

STL files and data to support: Improvements in methods for measuring the volume conductivity of electrically conductive carbon powders

Seth Kane, Cecily Ryan & Stephan Warnat
Electrically conductive carbon powders are commonly used as filler materials in polymers to create electrically semi-conductive composite materials for use in battery electrodes and anti-static applications. Current methods for characterizing the conductivity of these powders use two pistons to compress the powders. Two-piston methods are known to underestimate conductivity. This study develops a guard-electrode method based on ASTM D257 to better characterize the bulk conductivity and impedance spectra of electrically conductive powders. The conductivity and...

Influence of biomimicry structures on ecosystem function in a Rocky Mountain incised stream

James Reinert, Lindsey Albertson & James Junker
Rising levels of stream degradation have motivated a boom in restoration projects across the globe. However, post-restoration monitoring is still frequently lacking and does not always incorporate biotic responses to changes in the physical template. Beaver mimicry structures (BMS) are becoming a popular tool to restore degraded streams throughout the American West, but relatively little is known about how these installations influence both biotic and abiotic factors, with consequences for ecosystem functioning. We monitored basal...

Interspecific variation in evaporative water loss and temperature response, but not metabolic rate, among hibernating bats

Liam McGuire, Nathan Fuller, Yvonne Dzal, Catherine Haase, Brandon Klüg-Baerwald, Kirk Silas, Raina Plowright, Cori Lausen, Craig Willis & Sarah Olson
Hibernation is widespread among mammals in a variety of environmental contexts. However, few experimental studies consider interspecific comparisons, and for many unstudied (or understudied) species we must assume the underlying physiology of hibernation is comparable to the relatively few species that have been studied in detail. Studies of interspecific variation provide insight into general patterns of hibernation strategies. We studied 13 species of free-living bats, including populations spread over thousands of kilometers and diverse habitats....

Code in support of: Physical and chemical mechanisms that influence the electrical conductivity of lignin-derived biochar

Seth Kane, Rachel Ulrich, Abigail Harrington, Nicholas P. Stadie & Cecily Ryan
Lignin-derived biochar is a promising, sustainable alternative to petroleum-based carbon powders (e.g., carbon black) for electrode and energy storage applications. Prior studies of these biochars demonstrate that high electrical conductivity and good capacitive behavior are achievable. These studies also show high variability in electrical conductivity between biochars (~10^-2-10^2 S/cm). The underlying mechanisms that lead to desirable electrical properties in these lignin-derived biochars are poorly understood. In this work, we examine the causes of the variation...

Evolutionary sample size and consilience in phylogenetic comparative analysis

Jacob Gardner & Chris Organ
Phylogenetic comparative methods (PCMs) are commonly used to study evolution and adaptation. However, frequently used PCMs for discrete traits mishandle single evolutionary transitions. They erroneously detect correlated evolution in these situations. For example, hair and mammary glands cannot be said to have evolved in a correlated fashion because each evolved only once in mammals, but a commonly used model (Pagel’s Discrete) statistically supports correlated (dependent) evolution. Using simulations, we find that rate parameter estimation, which...

Analytic dataset informing modeling of winter species distributions of North American bat species

Sarah Olson, Meredith McClure, Catherine Haase, Carter Hranac, David Hayman, Brett Dickson, Liam McGuire, Daniel Crowley, Nathan Fuller, Cori Lausen & Raina Plowright
The fungal pathogen Pseudogymnoascus destructans and resultant white-nose syndrome (WNS) continues to advance across North America, infecting new bat populations, species, and hibernacula. Western North America hosts the highest bat diversity in the U.S. and Canada, yet little is known about hibernacula and hibernation behavior in this region. An improved understanding of where bats hibernate and the conditions that create suitable hibernacula is critical if land managers are to anticipate and address the conservation needs...

Dietary composition and fatty acid content of giant salmonflies (Pteronarcys californica) in two Rocky Mountain rivers

Michelle Briggs, Lindsey Albertson, Zach Maguire, Sophia Swart, Wyatt Cross, Cornelia Twining, Jeff Wesner, Colden Baxter & David Walters
Many aquatic invertebrates are declining or facing extinction from stressors that compromise physiology, resource consumption, reproduction, and phenology. However, the influence of these common stressors specifically on consumer-resource interactions for aquatic invertebrate consumers is only beginning to be understood. We conducted a field study to investigate Pteronarcys californica (i.e., the ‘giant salmonfly’), a large-bodied insect that is ecologically and culturally significant to rivers throughout the western U.S. We sampled gut contents and polyunsaturated fatty acid...
