View article: General predictions for the effects of warming on competition
General predictions for the effects of warming on competition Open
Understanding the effects of climate change on communities has been hindered by a lack of general theory for how temperature affects competition. To fill this knowledge gap, we integrated Modern Coexistence Theory and the Metabolic Theory …

Ecological acclimation: A framework to integrate fast and slow responses to climate change Open
Ecological responses to climate change occur across vastly different time‐scales, from minutes for physiological plasticity to decades or centuries for community turnover and evolutionary adaptation. Accurately predicting the range of ecos…

Mean daily temperatures predict the thermal limits of malaria transmission better than hourly rate summation Open
Temperature shapes the geographic distribution, seasonality, and magnitude of mosquito-borne disease outbreaks. Models predicting transmission often use mosquito and pathogen thermal responses measured at constant temperatures. However, mo…

Harnessing open science practices to teach ecology and evolutionary biology using interactive tutorials Open
Open science skills are increasingly important for a career in ecology and evolutionary biology (EEB) as efforts to make data and analyses publicly available continue to become more commonplace. While learning core concepts in EEB, student…

Biotic interactions structure zooplankton metacommunity dynamics following a summer heatwave Open
Despite the key role of biotic interactions in structuring ecological communities, their influence is often overlooked in predictions of how communities respond to environmental change.Here, we present an experimental test of hypotheses ba…

Temperature dependence of competitive ability is cold‐shifted compared to that of growth rate in marine phytoplankton Open
The effect of climate warming on community composition is expected to be contingent on competitive outcomes, yet approaches to projecting ecological outcomes often rely on measures of density‐independent performance across temperatures. Re…

Temperate species underfill their tropical thermal potentials on land Open
Understanding how temperature determines the distribution of life is necessary to assess species’ sensitivities to contemporary climate change. Here, we test the importance of temperature in limiting the geographic ranges of ectotherms by …

Rethinking disaster risk for ecological risk assessment Open
While disaster events are consequential, they are rare. Ecological risk assessment processes tend to estimate risk through an “expected value” lens that focuses on the most probable events, which can drastically underappreciate the importa…

Effects of thermal fluctuations on biological processes: a meta-analysis of experiments manipulating thermal variability Open
Thermal variability is a key driver of ecological processes, affecting organisms and populations across multiple temporal scales. Despite the ubiquity of variation, biologists lack a quantitative synthesis of the observed ecological conseq…
