How can policymakers and researchers develop effective insect resistance management guidelines? A quantitative and qualitative study of Brazilian farmers' perspectives and attitudes

PLANTS, PEOPLE, PLANET, Volume 5, Issue 5, Page 722-735, September 2023., 2023
Today, over 80% of the US and Brazil row crop acreage has plants expressing insecticidal proteins to prevent the damage caused by caterpillars. These plants (crops expressing Bacillus thuringiensis, Bt, toxins) have brought several benefits to farmers, the environment, and society.

Multilingualism for pluralising knowledge and decision making about people and nature relationships

People and Nature, Volume 5, Issue 3, Page 874-884, June 2023., 2023
Abstract The need for a pluralistic approach to biodiversity conservation science and policy is increasingly being recognized. We argue that plural perspectives require multilingualism in the sources and processes. Unless the linguistic bias and the related issues in terms of legitimacy and validity, resistance to inclusion, and knowledge coproduction ...

estar: An R package to measure ecological stability

Methods in Ecology and Evolution, Volume 17, Issue 4, Page 1090-1100, April 2026.
Abstract Assessing ecological stability is a key task in biodiversity monitoring and conservation. Quantifying stability is not trivial because its different aspects can be measured with various properties. However, to date, no software enables measuring different stability properties on ecological time‐series data.

GNPS Untargeted GC‐MS Metabolomic Analysis of Essential Oils From Duguetia lanceolata and Evaluation of Antimicrobial Activity

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.
Untargeted metabolomic analysis of the essential oil of D. lanceolata leaves collected in winter revealed that they are mostly composed of sesquiterpenes, while those collected in autumn showed a predominance of monoterpenes. Both essential oils displayed antimicrobial activity against bacterial and fungal species.

Structured Promoter Variability in Epigenetically Regulated Operons Contributes to Surface Adaptation in Salmonella

Microbial Biotechnology, Volume 19, Issue 2, February 2026.
We discovered that Salmonella uses structured, recurrent variation in epigenetically regulated promoter regions to fine‐tune gene expression, revealing a novel evolutionary strategy for surface adaptation. ABSTRACT Bacterial adaptation to dynamic and hostile environments often relies on the ability to modify surface structures, which are subjected to ...
