Data from: The effects of phylogeny, habitat, and host characteristics on the thermal sensitivity of helminth development

Jessica Phillips, Juan Vargas Soto, Samraat Pawar, Janet Koprivnikar, Daniel Benesh & Péter Molnár
Helminth parasites are part of almost every ecosystem, with more than 300 000 species worldwide. Helminth infection dynamics are expected to be altered by climate change, but predicting future changes is difficult due to lacking thermal sensitivity data for greater than 99.9% of helminth species. Here, we compiled the largest dataset to date on helminth temperature sensitivities and used the Metabolic Theory of Ecology to estimate activation energies (AEs) for parasite developmental rates. The median...

Anna's hummingbird (Calypte anna) physiological response to novel thermal and hypoxic conditions at high elevations

Austin Spence, Hannah LeWinter & Morgan Tingley
Many species have not tracked their thermal niches upslope as predicted by climate change, potentially because higher elevations are associated with abiotic challenges beyond temperature. To better predict if organisms can continue to move upslope with rising temperatures, we need to understand their physiological performance when subjected to novel high elevation conditions. Here, we captured Anna’s hummingbirds – a species expanding their elevational distribution in concordance with rising temperatures – from across their current elevational...

Redwood Creek Chinook salmon life cycle model code and data

Emily Chen, Nicholas Som, John Deibner-Hanson, David Anderson & Mark Henderson
Understanding the spatial and temporal habitat use of a population is a necessary step for restoration decision making. For Chinook salmon (Oncorhynchus tshawytscha), variation in their migration and habitat use complicate predicting how restoring habitats will impact total recruitment. To evaluate how juvenile life history variation affects a population’s response to potential restoration, we developed a stage-structured model for a Chinook salmon population in a northern California river with a seasonally closed estuary. We modeled...

Evolutionary history constrains heat tolerance of native and exotic tropical Zingiberales

Georgia G. Hernández, Timothy M. Perez, Oscar M. Vargas, W. John Kress, Ramón Molina-Bravo, Roberto A. Cordero & Carlos García-Robledo
Tropical wet forest plants experience relatively stable temperatures throughout the year. However, tropical forests represent a mosaic of habitats characterized by different temperatures. Heat tolerances are expected to be adapted to temperatures specific to their habitats. Although the heat tolerance of species sharing similar environments is expected to be similar, it is also possible that heat tolerance is constrained by evolutionary history because closely related species usually display similar physiologies. When exotic species are introduced...

Effects of community richness and competitive asymmetry on protozoa evolution in Sarracenia purpurea leaves

Thomas Miller, Abigail Pastore, Catalina Cuellar-Gempeler, Erin Canter & Olivia Mason
Predicting evolution in natural systems will require understanding how selection operates in multispecies communities. We predicted that the amount that traits evolve in multispecies mixtures would be less than the amount that would be predicted from the additive contributions of the pair-wise interactions and that subordinate species will be more likely to evolve in competitive systems than dominant species. We conducted an experimental test of these predictions using a guild of protozoans found in the...

A tail of plumage colouration: disentangling geographic, seasonal, and dietary effects on plumage colour in a migratory songbird

Sean Mahoney
Plumage ornamentation in birds serves critical inter- and intra-sexual signaling functions. While carotenoid-based plumage colouration is often viewed as a classic condition dependent sexually selected trait, plumage colouration can be influenced by a wide array of both intrinsic and extrinsic factors. Understanding the mechanisms underlying variation in colouration is especially important for species where the signaling function of ornamental traits is complex or the literature conflicting. Here, we examined variation in the yellow/orange tail feathers...

The effects of a half century of warming and fire exclusion on montane forests of the Klamath Mountains, California, USA

Melissa DeSiervo & Erik Jules
These files are the raw data used in the manuscript "Effects of a half century of warming and fire exclusion on montane forests of the Klamath Mountains, California, USA" Manuscript authors: Erik S. Jules, Melissa H. DeSiervo, Matthew J. Reilly, Drew S. Bost, and Ramona J. Butz Climate warming and altered disturbance regimes are changing forest composition and structure worldwide. Given that species often exhibit individualistic responses to change, making predictions about the cumulative effects...
