Interpretable and Predictive Models Based on High‐Dimensional Data in Ecology and Evolution

Joshua P. Jahner, C. Alex Buerkle, Dustin G. Gannon, Eliza M. Grames et autres

The proliferation of high-dimensional data in ecology and evolutionary biology raises the promise of statistical and machine learning models that are highly predictive and interpretable. However, high-dimensional data are commonly burdened with an inherent trade-off: in-sample prediction of outcomes will improve as …

When and Where We Can Expect to See Early Warning Signals in Multispecies Systems Approaching Tipping Points: Insights from Theory

Amy C. Patterson, Alexander Strang, Karen C. Abbott

AbstractEarly warning signals (EWSs) have the potential to predict tipping points where catastrophic changes occur in ecological systems. However, EWSs are plagued by false negatives, leading to undetected catastrophes. One reason may be because EWSs do not occur equally for all species …

Becoming common: Lack of competitors and of herbivores is not enough to explain invasiveness in Lamiaceae, the mint family

Amy C. Patterson

After habitat loss, exotic species are considered the greatest threat to biodiversity. However, some studies show that exotic species have minimal effects on biodiversity at large spatial scales. Here, we ask whether there is a fundamental difference between the reason exotic and …

Mechanisms of Invasion: How Invasive Species Eclipse the Competition

Amy C. Patterson

In an increasingly globalized world, invasive exotic species pose one of the greatest threats to native ecosystems. However, not all exotic species are invasive, which leads to a pressing question: what traits do certain exotic plants have that lead to invasiveness? One …
