Chapter
We present the historical development of cross-site/inter-site comparisons and synthesis by the Long Term Ecological Research (LTER) Network from 1980–2015. Comparative ecosystem research began to flourish after John Brooks of the National Science Foundation (NSF) challenged the LTER community in 1986 to function as a collaborating network of sites...
Chapter
The chapter explores a series of overlapping discussions from the 1960s to the mid-1970s concerning the need to preserve natural areas for ecological research and observation, as well as the need for ecologists to be advocates for ecological science in the light of modern environmental problems. The U.S. Forest Service was also actively promoting t...

Article
Full-text available
Trait-based ecology claims to offer a mechanistic approach for explaining the drivers that structure biological diversity and predicting the responses of species, trophic interactions and ecosystems to environmental change. However, support for this claim is lacking across broad taxonomic groups. A framework for defining ecosystem processes in term...
Article
Full-text available
The metabolic theory of ecology assumes that rates of selection and adaptation for organisms are functions of temperature. Niche theory predicts that strong selection pressure should simplify assemblages as species are extirpated and taxa pre-adapted for the new environment thrive. Here, we use closed mesocosms to test the prediction that higher te...

Humans are both fertilizing the world and depleting its soils, decreasing the diversity of aquatic ecosystems and terrestrial plants in the process. We know less about how nutrients shape the abundance and diversity of the prokaryotes, fungi, and invertebrates of Earth's soils. Here we explore this question in the soils of a Panama forest subject t...
Article
Full-text available
The Abundance-Adaptation Hypothesis argues that taxa with more individuals and faster generation times will have more evolutionary “experiments” allowing expansion into, and diversification within, novel habitats. Thus, as older taxa have produced more individuals over time, and smaller taxa have higher population sizes and faster generation times,...
