Data from: Combinations of reproductive, individual, and weather effects best explain torpor patterns among female little brown bats (Myotis lucifugus)

Nicole K. Besler & Hugh G. Broders
Heterothermic mammals can use torpor, a state of metabolic suppression, to conserve energy during times of limited food and poor environmental conditions. Females may use torpor throughout gestation and lactation; however, there are associated physiological and ecological costs with potential fitness consequences. Previous studies have controlled for, but not quantified the impact of interindividual variation on torpor patterns and understanding this may provide insight on why certain thermoregulatory responses are employed. The objective of this...

Data from: Patterns of nitrogen-fixing tree abundance in forests across Asia and America

Symbiotic nitrogen (N)‐fixing trees can provide large quantities of new N to ecosystems, but only if they are sufficiently abundant. The overall abundance and latitudinal abundance distributions of N‐fixing trees are well characterised in the Americas, but less well outside the Americas. Here, we characterised the abundance of N‐fixing trees in a network of forest plots spanning five continents, ~5,000 tree species and ~4 million trees. The majority of the plots (86%) were in America...

Data from: Riverine transport and nutrient inputs affect phytoplankton communities in a coastal embayment

Josef D. Ackerman, Christopher R. Farrow, Ralph E. H. Smith & Dave Snider
1. Rivers often transport phytoplankton to coastal embayments and introduce nutrients that can enrich coastal plankton communities. We investigated the effects of the Nottawasaga River on the nearshore (i.e., within 500 m of shore) phytoplankton composition along a 10 km transect of Nottawasaga Bay, Lake Huron in 2015 and 2016. Imaging flow cytometry was used to identify and enumerate algal taxa, which were resolved at sizes larger than small nanoplankton (i.e., > 5 mm). Multivariate...

Data from: Variation in juvenile Chinook salmon (Oncorhynchus tshawytscha) transcription among and within eight population crosses from British Columbia, Canada

Shelby D. Toews, Kyle W. Wellband, Brian Dixon & Daniel D. Heath
Phenotypic differences among populations within a species have been reported for a variety of traits, ranging from life history to physiology to gene transcription. Population-level phenotypic variation has been attributed to genetic differences resulting from genetic drift and/or local adaptation as well as environmental differences resulting from plasticity. We studied population- and family-level variation in gene transcription for 22 fitness-related genes, comprising immune, growth, metabolic, and stress processes in Chinook salmon (Oncorhynchus tshawytscha). We created...

Data from: Mean and variance of phylogenetic trees

Daniel G. Brown & Megan Owen
We describe the use of the Fréchet mean and variance in the Billera-Holmes-Vogtmann (BHV) treespace to summarize and explore the diversity of a set of phylogenetic trees. We show that the Fréchet mean is comparable to other summary methods, and, despite its stickiness property, is more likely to be binary than the majority-rules consensus tree. We show that the Fréchet variance is faster and more precise than commonly used variance measures. The Fréchet mean and...

Peatland vegetation: field and laboratory measurements of carbon dioxide fluxes and spectral reflectance

K.J. Lees, J.M. Clark, T. Quaife, R.R.E. Artz, M. Khomik & J. Ritson
This dataset includes laboratory and field measurements of carbon fluxes and spectral reflectance for peatland vegetation including Sphagnum species. It also includes satellite data relating to the development and use of a Temperature and Greenness (TG) model, and an annual Temperature, Greenness and Wetness (TGWa) model. The laboratory data includes Gross Primary Productivity (GPP) and respiration data from samples of Sphagnum capillifolium and Sphagnum papillosum which were collected from the Forsinard Flows RSPB reserve (Northern...

Data from: Stochastic and deterministic processes drive wetland community assembly across a gradient of environmental filtering

Jody Daniel-Simon, Jennifer Erin Gleason, Karl Cottenie & Rebecca C Rooney
The role of deterministic and stochastic processes in community assembly is a key question in community ecology. We evaluated the effect of an abiotic filter (hydroperiod) on the partitioned diversity of three taxonomic groups (birds, vegetation, macroinvertebrates) from prairie pothole wetlands in Alberta, Canada, which naturally vary in water permanence. We observed that alpha and gamma diversity were higher in permanent than temporary wetlands (16-25% and 34-47% respectively, depending on the taxon). This suggests an...

Data from: Concordance in wetland physicochemical conditions, vegetation, and surrounding land cover is robust to data extraction approach

Adam J. Kraft, Derek T. Robinson, Ian S. Evans & Rebecca C. Rooney
Concordance among wetland physicochemical conditions, vegetation, and surrounding land cover may result from the influence of land cover on the sources of plant propagules, on physicochemical conditions, and their subsequent determination of growing conditions. Alternatively, concordance may result if differences in climate, soils, and species pools are spatially confounded with differences in human population density and land conversion. Further, we expect that land cover within catchment boundaries will be more predictive than land cover in...

What is Queer Game Studies?

Jason Lajoie
Addressing a lacuna in games studies, Jason Lajoie makes a case for why a queer games studies is needed, and he shows how these two areas of study are united in Bonnie Ruberg's and Adrienne Shaw's collection.
