Socioeconomic roots of academic faculty

Tenure-track faculty are up to 25 times more likely to have a parent with a Ph.D. Moreover, this rate nearly doubles at prestigious universities and is stable across the past 50 years.

Women, non-native English speakers & those form low-income countries are disadvantaged in science but by how much? We found that women with non-English first languages from low-income countries publish up to 70% fewer in English than their counterparts. 1/5

Equity in science is a beautiful lie β€” and I’m done pretending | Nature Science isn’t really moving towards equity; institutions are just perfecting the appearance of equity. We need to build an alternative system. Science isn’t really moving towards equity; institutions are just perfecting the appearance of equity. We need to build an alternative system.

I wrote my new Nature World View in this transition β€” one last reflection before leaving Colombia. It explains why inequities persist in science, even when dressed up as inclusion, and why we must stop mistaking access for change. πŸ‘‰ rdcu.be/eGEun

A new study in Nature Climate Change shows contrasting biological production trends over land and ocean. Led by Yulong Zhang at Duke. I am glad to be part of the team. The last study that looked at production over both land and ocean was published in 1998.

How do tropical #trees deal with droughts? The answer is published today in @science.org

Our pantropical #treering analysis revealed 2.5% growth reduction during #drought years. Yet, growth declined by >10% in 1/4 of 500 study sites, and in hotter & drier regions.

Tree methane exchange in a changing world Nature Reviews Earth & Environment, Published online: 19 June 2025; doi:10.1038/s43017-025-00692-9Tree methane exchange is an important component of the terrestrial and global methane budget. This Perspective explores the mechanisms underlying why wetland trees are a net source of methane to the atmosphere and upland trees are a net sink, and the effect environmental changes will have on these processes.

New in @sciencemagazine, a review on Scaling plant responses to heat (www.science.org/doi/10.1126/...). Increased temperature along with acute heat waves threaten the ability of terrestrial vegetation to act as a carbon sink, but predicting how plants will respond to heat is challenging.

Deforestation in Colombia increased in 2024 after two years of decline, just as the environment ministry had warned since April last year.

Experts fear that the increase will continue in 2025 and that armed groups will continue to hinder the progress of conservation strategies with communities.

Our new research shows that forest recovery from tree mortality has slowed in recent decades. This reduction is primarily associated with rising temperatures and increased water scarcity. Recovery of forest canopy water content lags behind that of vegetation greenness
