Navigating the seven seas of arthropod collection protocols: Metabarcoding arthropod diversity in a tropical forest

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2395-2407, October 2025.
Abstract Insects and other arthropods represent one of the most diverse groups of life on Earth, with an estimated 70% of species awaiting discovery. Advances in DNA‐based tools have accelerated species discovery, while high‐throughput sequencing has enabled large‐scale biodiversity surveys.

calibrar: An R package for fitting complex ecological models

Methods in Ecology and Evolution, Volume 16, Issue 3, Page 507-519, March 2025.
Abstract The fitting or parameter estimation of complex ecological models is a challenging optimisation task, with a notable lack of tools for fitting complex, long runtime or stochastic models. calibrar is an R package that is dedicated to the fitting of complex models to data.

Modelling alternative management strategies of invasive tree species at the expansion front: Ligustrum lucidum as a case study

Ecological Solutions and Evidence, Volume 6, Issue 1, January–March 2025.
The management of invasive non‐native species is a global challenge, particularly for long‐lived trees. Individual‐based models (IBMs) and expert knowledge are valuable tools for evaluating different strategies to control the population dynamics and range expansion of invasive species.

An open‐source LED lamp for use with the LI‐6800 photosynthesis system

Applications in Plant Sciences, Volume 13, Issue 1, January-February 2025.
Abstract Premise Controlling light flux density during carbon dioxide assimilation measurements is essential in photosynthesis research. Commercial lamps are expensive and are based on monochromatic light‐emitting diodes (LEDs), which deviate significantly in their spectral distribution compared to sunlight.

Parents' illness representations of their child with anorexia nervosa: A systematic review of qualitative studies using the common‐sense model

International Journal of Eating Disorders, Volume 57, Issue 5, Page 1049-1068, May 2024.
Abstract Objective Research indicates that parents experience distress while caring for a child with anorexia nervosa. Applying the Common Sense Model of Self‐Regulation (CSM), a framework to describe responses to illness may help to understand the antecedents of parental distress, which could inform how to support parents in treatment. The aim of this

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on the microbiological criteria for Vibrio cholerae, as additional control measures at border control posts, applicable to imported frozen prawns and other fishery products

Food Risk Assess Europe, Volume 2, Issue 2, April 2024.
Abstract In recent years, an increase in the presence of Vibrio spp. in fishery products has been detected as a result of phenomena associated with climate change, international trade and the development of new detection and diagnosis methods. Specifically, it is the serogroups of V.
