Cellular Morphometric Analysis (CellMorph)—a comprehensive imaging‐based tool for quantifying cellular phenotype heterogeneity and dynamics across biological processes

open access: yesThe FEBS Journal, EarlyView.
CellMorph is a groundbreaking tool that allows researchers to analyze multiple features from single cells, including cell size and shape, cytosolic staining and subcellular texture, nuclear staining, and morphometry. By evaluating images from both bright‐field and fluorescence microscopy, it also tracks changes in living cells during key processes such

Lack of Compliance in Gillnet Fisheries Regulations Increases Risk to a Vulnerable Species

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT This article presents an analysis of regulatory compliance in a Brazilian gillnet fishery, based on Vessel Monitoring System (VMS) tracking data. Satellite transmissions records, interpreted as proxies for gillnet haulings events, were analyzed and classified using a neural network to assess the level of compliance of the gillnet fleet.
