Colonization, covariance and colour: Environmental and ecological drivers of diversity–stability relationships [PDF]
Journal of Theoretical Biology, 2013 Understanding the mechanisms that underlie the relationship between community diversity and biomass stability is a fundamental topic in ecology. Theory has emphasized differences in species-specific responses to environmental fluctuations as an important stabiliser of total biomass fluctuations.

Impact of Environmental Covariation in Growth and Mortality on Evolving Maturation Reaction Norms [PDF]
The American Naturalist, 2011 Maturation age and size have important fitness consequences through their effects on survival probabilities and body sizes. The evolution of maturation reaction norms in response to environmental covariation in growth and mortality is therefore a key subject of life-history theory.

Detecting the influence of environmental covariates on animal movement: a semivariance approach
Methods in Ecology and Evolution, 2016 Summary Movements of organisms are influenced by environmental variation. For example, the movement rates of animals in unsuitable habitats are often different from movement rates of animals foraging in high‐quality habitats. Different statistical methods to detect such effects exist, but they often rely on complete and regularly sampled data or ...

Predicting Imminent Cyanobacterial Blooms in Lakes Using Incomplete Timely Data
Water Resources ResearchToxic cyanobacterial blooms (CBs) are becoming more frequent globally, posing a threat to freshwater ecosystems. While making long‐range forecasts is overly challenging, predicting imminent CBs is possible from precise monitoring data of the underlying ...

The Effects of Spanking on Psychosocial Outcomes: Revisiting Genetic and Environmental Covariation
Journal of Experimental Criminology, 2020 The current research analyzed data from the Children of the National Longitudinal Survey of Youth (Study 1) and conducted simulation models using parameters from the literature (Study 2) to provide a summative evaluation of the psychosocial effects of spanking with regard to genetic and nonshared environmental covariation. Results of Study 1 replicated

Metagenomic Covariation Along Densely Sampled Environmental Gradients in the Red Sea [PDF]
The ISME Journal, 2016 Abstract Oceanic microbial diversity covaries with physicochemical parameters. Temperature, for example, explains approximately half of global variation in surface taxonomic abundance. It is unknown, however, whether covariation patterns hold over narrower parameter gradients and spatial scales, and extending to mesopelagic depths.

Environmental Covariate Representation of Seasonal U.S. Tornado Frequency [PDF]
Journal of Applied Meteorology and Climatology, 2019 AbstractThe significant tornado parameter is a widely used meteorological composite index that combines several variables known to favor tornadic supercell thunderstorms. This research examines the spatial relationship between U.S. tornado frequency and the significant tornado parameter (the predictor covariate) across four seasons in order to ...
