Estimating distances to desertification points from dryland ecosystem images

The paper estimates the distance to degradation points in dryland ecosystems from images, validated on simulated landscapes and applied to a global dataset to identify fragile sites.

Self-supervised learning to predict intrahepatic cholangiocarcinoma transcriptomic classes on routine histology

This paper develops a self-supervised learning model to predict iCCA transcriptomic classes from histological images, achieving good to very good performance in multiple validation sets.

The interplay of facilitation and competition drives the emergence of multistability in dryland plant communities

This study identifies three types of multistability in dryland plant communities driven by facilitation and competition under varying stress levels.

Telling mutualistic and antagonistic ecological networks apart by learning their multiscale structure

The paper distinguishes between mutualistic and antagonistic ecological networks using multiscale structure analysis and machine learning, finding structural differences beyond global metrics.

Quality matters: stoichiometry of resources modulates spatial feedbacks in aquatic-terrestrial meta-ecosystems

The paper models how resource stoichiometry in aquatic-terrestrial ecosystems affects spatial feedbacks and production through subsidy flows.

Landscape structure and dispersal rate drive large scale catastrophic shifts in spatially explicit metapopulations

This study shows that landscape structure and dispersal rate influence the occurrence and reversibility of catastrophic shifts in spatially structured metapopulations.

Do closely related species interact with similar partners? Testing for phylogenetic signal in bipartite interaction networks

The paper evaluates two methods for detecting phylogenetic signal in bipartite interaction networks and recommends using network permutations for significance testing.

Genomic and epidemiological evidence of a dominant Panton-Valentine leucocidin-positive Methicillin Resistant Staphylococcus aureus lineage in Sri Lanka with spread to the United Kingdom and Australia

The paper conducts genomic analysis of MRSA in Sri Lanka, identifying a dominant PVL-positive ST5-MRSA-IVc lineage that spreads internationally.

Methicillin resistant Staphylococcus aureus emerged long before the introduction of methicillin in to clinical practice

This study shows that MRSA emerged in the mid-1940s, long before methicillin was introduced, due to prior use of first-generation beta-lactams.
