Biomass production of tropical trees across space and time: The shifting roles of diameter growth and wood density

open access: yesJournal of Ecology, Volume 113, Issue 11, Page 3141-3158, November 2025.
Diameter growth is an important and good indicator of forest carbon production. However, size‐related changes in wood density, which are usually neglected, are critical for accurate short‐ and long‐term carbon assessments, especially in tropical humid sites.

Monitoring population extinction risk with community science data

open access: yesJournal of Applied Ecology, Volume 62, Issue 9, Page 2133-2147, September 2025.
Our modelling framework provides a robust, computationally efficient and easy‐to‐apply tool for monitoring local persistence probability that can support global conservation efforts. This will complement the monitoring of species population viability in places where standardized monitoring is still lacking, but community science observations are common.

Using aerial thermography to map terrestrial thermal environments in unprecedented detail

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 8, Page 1688-1702, August 2025.
Abstract The accurate quantification of thermal environments is crucial for predicting the impacts of climate change across ecosystems. Two major obstacles exist in mapping biologically relevant thermal landscapes: (1) overcoming the mismatch between the scale at which environmental data are typically collected and the scale at which a particular ...

Co-expression gene module analysis in response to attenuated cercaria vaccine reveals a critical role for NK cells in protection against Schistosoma mansoni

open access: yesParasites & Vectors
Background Despite decades of research, an effective schistosomiasis vaccine remains elusive. The radiation-attenuated (RA) cercarial vaccine remains the best model for eliciting high levels of protection.

Detection of canine external ear canal lesions using artificial intelligence

open access: yesVeterinary Dermatology, Volume 36, Issue 4, Page 424-432, August 2025.
Background – Early and accurate diagnosis of otitis externa is crucial for correct management yet often can be challenging. Artificial intelligence (AI) is a valuable diagnostic tool in human medicine. Currently, no such tool is available in veterinary dermatology/otology.

ESR1 Variants and Subcontinental Genomic Ancestry: Insights from the 1000 Genomes Project and Native American Populations

open access: yesClinical Pharmacology &Therapeutics, Volume 118, Issue 1, Page 232-241, July 2025.
The ESR1 gene is relevant in breast cancer treatments in the pharmacogenetics context. However, Native, African, and mixed populations are known to be underrepresented in genomic studies. This is particularly important given that the difference in variants' frequencies among different populations can lead to population‐specific clinical implications ...
