Forests worldwide are increasingly exposed to soil drought under climate change, with their fates depending on the ability to maintain essential fu...

Background tree mortality is the ambient, natural death of trees that occurs without major disturbances. Using data from more than 24,000 forest plots across Canada and the United States, we found th...

The authors integrate dendrochronological records with range shifts to show that shifts in montane tree species are tightly linked to tree hydraulic properties. While climate-sensitive species track w...

Different tropical tree species can vary in their ability to withstand drought — and so too, it seems, can distinct populations of the same tree species.

Birds may have been burying Jeffrey pine seeds up high for thousands of years. But now that they’re sprouting, this new species of subalpine tree may change the playing field.

Satellite observations reveal accelerating aboveground biomass loss across Europe’s forests since 2018, increasingly driven by natural disturbances. These trends weaken the forest carbon sink and chal...

The authors combine satellites, repeat airborne lidar, dynamic global vegetation models and field plot monitoring across the conterminous USA to show widespread continued carbon accumulation in mature...

In this role, you will:Lead the oversight of a dendrochronology laboratory in collaboration with the Director, including the mentoring, training,...

We deployed automated point dendrometers on 35 trees representing three life history strategies in an everwet subtropical forest with 3500 mm rain annually and no pronounced dry season. Contrary to t....

This study explores climate-driven tree mortality risk beyond summer drought. It links rising tree mortality in France to distinct seasonal climate anomalies, including winter and spring warming, diff...

Long-term carbon sequestration as woody biomass in oaks is decoupled from photosynthesis and more sensitive to climate change.

Examples of cross-sectional images of branchlets at 4× and 40×.

The Trump administration has spent months investigating the lab after a Chinese postdoc was charged with smuggling biological material into the country.

Biology department chair Armin Moczek said experiments are being aborted every day during the shutdown, including projects months in the testing.

Move comes after Roger Innes complained about the government’s prosecution of Chinese postdocs

Variations of oxygen isotopes δ18O in tree rings provide critical insights into past climate and tree physiological processes, yet the mechanisms shaping the intra-annual δ18O signals remain incompl...

Tree crown damage from disturbance events strongly influences forest demography, yet its effect on stem growth remains poorly quantified, with both...

Precipitation trends toward less frequent and more intense wet days are broadly co-located across land surfaces Trends toward less frequent and more intense wet days are one of the most, if not t...

The browning or loss of tree leaves that can be observed during droughts may be a coping mechanism to deal with dry circumstances by avoiding additional water stress.

Boreal forests provide considerable global land carbon storage and uptake, but they are being rapidly transformed to managed secondary forests, with poorly quantified implications for ecosystem carbon...

***PhD and MSc openings – Movement ecology and conservation*** I will periodically support graduate students, postdocs, and other staff through the Biology Department at the University of New…

Tree-ring δ18O from Abies guatemalensis in Central America captures interannual variations in boreal summer rainfall Lighter δ18O years are associated with a weakening of the Caribbean Low-Level ...

Explore plant interactions in forest environments at all levels from micro- to macro-scales and across the whole spectrum of plant biology.

A study published this week shows that how trees store and use radiocarbon left over from ancient solar storms can tell scientists a lot about these ancient storms and help them refine estimates of…

This study finds that native tree extinctions and alien naturalizations are pushing forests towards fast-growing, resource-demanding species. This global shift could affect carbon storage and ecosyste...

Tree longevity is thought to increase in harsh environments, but global evidence of drivers is lacking. Here, the authors find two different pathways for tree longevity: slow growth in resource limite...
