Effects of TcFLA‐1BP and TcGP72 Deletion on the Infectivity and Survival of Trypanosoma cruzi in Cell Cultures

Cell Biology International, Volume 49, Issue 11, Page 1395-1410, November 2025.
ABSTRACT Chagas disease, caused by the protozoan Trypanosoma cruzi, is a neglected tropical disease with limited treatment options and no available vaccine. Understanding the role of proteins in the parasite's biological cycle is critical for advancing vaccine development and optimizing therapies.

Monitoring population extinction risk with community science data

Journal 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

Methods 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 ...

Sample size for morphological traits of pigeonpea

Semina: Ciências Agrárias, 2015
The objectives of this study were to determine the sample size (i.e., number of plants) required to accurately estimate the average of morphological traits of pigeonpea (Cajanus cajan L.) and to check for variability in sample size between evaluation ...

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

Clinical 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 ...

Spatially nested species distribution models (N‐SDM): An effective tool to overcome niche truncation for more robust inference and projections

Journal of Ecology, Volume 113, Issue 7, Page 1588-1605, July 2025.
N‐SDMs are key tools to develop untruncated regional climate change forecasts of species distributions at fine resolution over restricted extents. While several N‐SDM approaches were proposed, there is currently no universal solution suggesting that further developments and testing are crucial if we are to derive robust future projections of species ...

TinyCO2: High‐performance, low‐cost CO2 enrichment for field‐grown plants

Methods in Ecology and Evolution, Volume 16, Issue 7, Page 1389-1396, July 2025.
Abstract Rising atmospheric CO2 levels place terrestrial ecosystems under novel environmental conditions, and research in field settings is key to understanding how real plant communities will respond. Despite decades of progress in elevated CO2 (eCO2) experiments, major gaps persist in our knowledge of plant responses to interacting influences of ...
