New PNAS paper: Intensive leaf cooling promotes tree survival during a record heatwave – Macrosystems Ecology Laboratory
A guest post by lead author and lab postdoc Brad Posch – The summer of 2023 in Phoenix, AZ, was (at the time) the hottest ever recorded. But it’s not just in the southwest United States where…
New paper in Ecology Letters: Predicting and Prioritising Community Assembly: Learning Outcomes via Experiments – Macrosystems Ecology Laboratory
We just put out a new paper focusing on a classic and challenging set of questions in community ecology. The first question is about predicting: how a community’s composition changes over tim…
New paper: Leaf venation network architecture coordinates functional trade-offs across vein spatial scales: evidence for multiple alternative designs – Macrosystems Ecology Laboratory
Lab postdoc Ilaine shares her new paper in New Phytologist! If you ever spend time looking at leaves of different species, you probably noticed that the way leaf veins are organized varies enormous…
New paper by postdoc Ilaine Matos: Negative allometry of leaf xylem conduit diameter and double-wall thickness: implications for collapse safety – Macrosystems Ecology Laboratory
Like a straw can collapse under the suction of a thirsty drinker, the xylem conduits in leaves can collapse as water potential declines during droughts (Figure 1). In collapsed conduits the water f…
New paper: Statistical inference methods for n-dimensional hypervolumes – Macrosystems Ecology Laboratory
Lab undergraduate student Dan Chen (now graduated!) just published a new methods paper on doing statistical inference on hypervolumes. It provides some important extensions to the hypervolume R pac…
New open-access book: Place-Based Scientific Inquiry: A Practical Handbook for Teaching Outside – Macrosystems Ecology Laboratory
Our new book just came out, building on a decade of K-12 education work at Sky School. You can buy the print version (all royalties donated), or also read the book freely online or download a PDF. …
Congratulations to Courtenay – the lab’s first graduating PhD student – Macrosystems Ecology Laboratory
Courtenay Ray is graduating this spring after starting in the lab in 2017. Her work has focused on plant community ecology and species interactions (especially those involving seeds) on Mt. Baldy i…
New paper: Climate lags and genetics determine phenology in quaking aspen (Populus tremuloides) – Macrosystems Ecology Laboratory
Why does tree phenology (spring leaf out and autumn leaf drop) vary across space and time? Most explanations focus on the role of climate on immediate physiology. However not all genotypes within a…
New paper: Predicting and controlling ecological communities via trait and environment mediated parameterizations of dynamical models – Macrosystems Ecology Laboratory
Can we leverage functional traits to predict or control the dynamics of species-rich communities? We just had a new paper come out exploring these ideas. You can read it at Oikos or download a PDF.…
New paper: Plant water use theory should incorporate hypotheses about extreme environments, population ecology, and community ecology – Macrosystems Ecology Laboratory
How and why do plants use water? We just wrote an opinion piece on this topic, calling for a broader appreciation for the multiple values of water to plants, beyond its utility for instantaneous ca…
New paper: Linking microenvironment modification to species interactions and demography in an #alpine plant community – Macrosystems Ecology Laboratory
(guest post by lab PhD student + lead author Courtenay Ray) Plants modify microenvironments by altering nearby abiotic conditions, such as ground temperatures, soil moisture, and nutrient availabil…
#AGU22: presentation by lab student Mickey Boakye on fern evolution/ecophysiology – Macrosystems Ecology Laboratory
This week at the AGU meeting in Chicago, lab PhD candidate Mickey Boakye will be presenting the work he did with lab honors undergraduate student Jason To on fern evolution, Please give his poster …
New paper: Bird extinctions threaten to cause disproportionate reductions of functional diversity and uniqueness – Macrosystems Ecology Laboratory
Jarome Ali just led a new paper on bird extinctions, using hypervolume methods to assess how functional diversity varies for almost all species of birds under different extinction risks. This wa…
