Identification of students' mental models about the milk transformation in yogurt [PDF]

open access: yes, 2017
A review of the scientific literature reveals that there are still few researches on the conceptions of secondary school students about chemical reactions involving microorganisms, especially those related to the mental models that students use in their ...

Long‐term trends of epibionts reflect Mediterranean striped dolphin abundance shifts caused by morbillivirus epidemics

open access: yesJournal of Animal Ecology, Volume 95, Issue 3, Page 553-569, March 2026.
This original research piece demonstrates, through empirical and theoretical modelling approaches, that the epibionts of striped dolphins indicate dolphin abundance shifts caused by epidemics of dolphin morbillivirus (DMV). In addition, we provide the first SIR model to investigate the epidemiology of DMV in western Mediterranean striped dolphins ...

The making of novel ecosystems: A process‐based framework for measurement, analysis and application

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 3, Page 683-704, March 2026.
Abstract Ecological novelty is emerging rapidly due to global change drivers such as climate shifts, species introductions, defaunation, and land‐use transformation. These changes challenge how we assess, understand and manage ecosystems in the Anthropocene.

Selective Formation of Pd‐DNA Hybrids Using Tailored Palladium‐Mediated Base Pairs: Towards Heteroleptic Pd‐DNA Systems

open access: yesAngewandte Chemie, Volume 136, Issue 11, March 11, 2024.
The selective creation of Pd‐DNA supramolecular structures using the [Pd(Aqa)] complex (Aqa=8‐amino‐4‐ hydroxyquinoline‐2‐carboxylic acid) highlights its enhanced affinity for cytosine compared to the previously reported [Pd(Cheld)] (Cheld=chelidamic acid).

Advancing Water Security in the Tropical and Subtropical Regions: An Integrative Topic Modeling Approach

open access: yesWorld Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,
