The importance of coupled herbivore-climate interactions in triggering and reinforcing shrub encroachment processes
Ecological insight through machine learning
In a new paper published in Methods in Ecology and Evolution, Jornada LTER scientists, led by Dr. Quiyan Yu, review salient methods in machine learning algorithms and evaluate their effect on successful ecological inference. A number of recommendations emerged, including the removal of spurious (correlated but not functionally important) variables from ML models, and the

The promise of distributed global ecology experiments
In a new piece in the journal BioScience (Yahdjian et al. 2021), ecologists with ties to the DroughtNet and LTER networks argue that coordinated distributed experiments, such as the DroughtNet International Drought Experiment and NutNet, should expand to cover more of the globe. Such experiments hold great promise for understanding ecosystem sensitivity to a range

One Day in the Desert
Join Mariana and her classmates from Las Cruces, New Mexico, as they take a field trip to the Chihuahuan Desert Nature Park. Mariana is concerned that she won’t be able to find anything interesting about the desert to tell her Eco Pen Pals from French Polynesia and the Pacific Northwest. However, after a series of

Long-Term Trends in Ecological Systems: A Basis for Understanding Responses to Global Change (EcoTrends book)
The EcoTrends Editorial Committee sorted through vast amounts of historical and ongoing data from 50 long-term research sites in the United States and Antarctica to present in a logical format the variables commonly collected. This work provides cross-site comparisons of ecological responses to global change drivers, as well as long-term trends in global change drivers
