Fires in the Amazon Region: Quick Policy Review

open access: yesDevelopment Policy Review, Volume 40, Issue 5, September 2022., 2022
Summary Motivation The combination of institutional weaknesses, climate change, and overexploitation is increasingly recognized as endangering the Amazon forest. These three factors made 2020 the worst year for forest fires recorded in the previous 60 years.

Flexible drought deciduousness in a neotropical understory herb

open access: yesAmerican Journal of Botany, Volume 109, Issue 8, Page 1262-1272, August 2022., 2022
Progression of leaf loss and growth between wet seasons. Abstract Premise Adaptive divergence across environmental gradients is a key driver of speciation. Precipitation seasonality gradients are common in the tropics, yet drought adaptation is nearly unexplored in neotropical understory herbs. Here, we examined two recently diverged neotropical spiral

GSK‐3β S9A overexpression leads murine hippocampal neural precursors to acquire an astroglial phenotype in vivo

open access: yesDevelopmental Neurobiology, Volume 81, Issue 5, Page 710-723, July/August 2021., 2021
Abstract The addition of new neurons to the existing hippocampal circuitry persists in the adult dentate gyrus (DG). During this process, named adult hippocampal neurogenesis (AHN), adult hippocampal progenitor cells (AHPs) give rise to newborn dentate granule cells (DGCs).

Thermal niche traits of high alpine plant species and communities across the tropical Andes and their vulnerability to global warming

open access: yesJournal of Biogeography, Volume 47, Issue 2, Page 408-420, February 2020., 2020
Abstract Aim The climate variability hypothesis (CVH) predicts that locations with reduced seasonal temperature variation select for species with narrower thermal ranges. Here we (a) test the CVH by assessing the effect of latitude and elevation on the thermal ranges of Andean vascular plant species and communities, and (b) assess tropical alpine ...

The Tariff Trap: Why Funding Health Programs Through Tariffs Harms Both Health and Democracy

open access: yesWorld Medical &Health Policy, Volume 18, Issue 2, June 2026.
ABSTRACT In 2025, the Trump Administration imposed significant tariffs on imports to the US as part of aggressive trade negotiations with other countries. Tariffs have important impacts on health that include increases in the prices that consumers and businesses pay for goods and potential damage to global supply chains.

Species Limits and Hybridization in Andean Leaf‐Eared Mice (Phyllotis)

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
Diversification of Phyllotis coincided with mid‐ to late‐Pleistocene climate change. Species delimitation revealed cryptic diversity within several nominal forms. Genomic analyses revealed evidence for introgressive hybridization. ABSTRACT Leaf‐eared mice (genus Phyllotis) are among the most widespread and abundant small mammals in the Andean Altiplano,

Diet of Andean Leaf‐Eared Mice (Phyllotis) Living at Extreme Elevations on Atacama Volcanoes: Insights From Metagenomics, DNA Metabarcoding, and Stable Isotopes

open access: yesEcology and Evolution, Volume 14, Issue 11, November 2024.
On the flanks of > 6000 m Andean volcanoes that tower over the Atacama Desert, leaf‐eared mice (Phyllotis vaccarum) live at extreme elevations that surpass known vegetation limits. We used a combination of metagenomics, DNA metabarcoding, and stable isotope analyses to investigate the diet of mice living in these extreme environments.

Scouts vs. usurpers: alternative foraging strategies facilitate coexistence between neotropical Cathartid vultures

open access: yesIbis, Volume 166, Issue 4, Page 1368-1383, October 2024.
Understanding how diverse assemblages of scavengers can coexist on shared ecological resources is a fundamental challenge in community ecology. However, current approaches typically focus on behaviour at carcass provisioning sites, missing how important differences in movement behaviour and foraging strategies can facilitate sympatric species ...
