Data from: Comparing process-based and constraint-based approaches for modeling macroecological patterns

Xiao Xiao, James P. O'Dwyer & Ethan P. White
Ecological patterns arise from the interplay of many different processes, and yet the emergence of consistent phenomena across a diverse range of ecological systems suggests that many patterns may in part be determined by statistical or numerical constraints. Differentiating the extent to which patterns in a given system are determined statistically, and where it requires explicit ecological processes, has been difficult. We tackled this challenge by directly comparing models from a constraint-based theory, the Maximum...

Data from: Warming alters food web-driven changes in the CO2 flux of experimental pond ecosystems

Trisha B. Atwood, Edd Hammill, Pavel Kratina, Hamish S. Greig, Jonathan B. Shurin & John S. Richardson
Evidence shows the important role biota play in the carbon cycle, and strategic management of plant and animal populations could enhance CO2 uptake in aquatic ecosystems. However, it is currently unknown how management-driven changes to community structure may interact with climate warming and other anthropogenic perturbations to alter CO2 fluxes. Here we showed that under ambient water temperatures, predators (three-spined stickleback) and nutrient enrichment synergistically increased primary producer biomass, resulting in increased CO2 uptake by...

Data from: Olfaction contributes to pelagic navigation in a coastal shark

Andrew P. Nosal, Yi Chao, John D. Farrara, Fei Chai & Philip A. Hastings
How animals navigate the constantly moving and visually uniform pelagic realm, often along straight paths between distant sites, is an enduring mystery. The mechanisms enabling pelagic navigation in cartilaginous fishes are particularly understudied. We used shoreward navigation by leopard sharks (Triakis semifasciata) as a model system to test whether olfaction contributes to pelagic navigation. Leopard sharks were captured alongshore, transported 9 km offshore, released, and acoustically tracked for approximately 4 h each until the transmitter...

Data from: Habitat monitoring and projections for threatened Canada lynx: linking the Landsat archive with carnivore occurrence and prey density

Erin M. Simons-Legaard, Daniel J. Harrison & Kasey R. Legaard
Habitat degradation is the leading threat to US federally listed species, but monitoring changes in habitat extent, fragmentation or quality is not generally included in species recovery plans. Consecutive satellite images of the same area through time are commonly used to assess landscape changes, and image data are increasingly used to generate predictor variables for species–habitat models. A time series of satellite images has, however, rarely been used in conjunction with a species–habitat model to...

Data from: Sex ratio variation shapes the ecological effects of a globally introduced freshwater fish

David C. Fryxell, Heather A. Arnett, Travis M. Apgar, Michael T. Kinnison & Eric P. Palkovacs
Sex ratio and sexual dimorphism have long been of interest in population and evolutionary ecology, but consequences for communities and ecosystems remain untested. Sex ratio could influence ecological conditions whenever sexual dimorphism is associated with ecological dimorphism in species with strong ecological interactions. We tested for ecological implications of sex ratio variation in the sexually dimorphic western mosquitofish, Gambusia affinis. This species causes strong pelagic trophic cascades and exhibits substantial variation in adult sex ratios....
