Temporal and spatial variability in availability bias has consequences for marine bird abundance estimates during the non-breeding season

This study investigates variability in availability bias for marine birds during the non-breeding season and presents species- and area-specific correction factors to improve abundance estimates.

Spatial refuges and nutrient acquisition predict the outcome of evolutionary rescue in evolving microbial populations

This study shows spatial refuges can rescue microbial populations from stress when nutrients are high, but may limit adaptations to other environmental factors.

CRISPR Screening in Tandem with Targeted mtDNA Damage Reveals WRNIP1 Essentiality

The paper uses mtDNA-damaging agents and CRISPR screening to identify genes essential for mtDNA damage response, finding WRNIP1 essential for mtDNA repair and mitochondrial turnover.

Public goods exploitation is reduced in species-rich microbial communities

The paper shows that in diverse microbial communities, siderophore exploitation by non-producers is reduced due to the presence of key species that inhibit non-producer growth.

SCF-FBXW7 regulates G2-M progression through control of CCNL1 ubiquitination

This study identifies CCNL1 as a new substrate of SCF-FBXW7 and shows its role in regulating G2-M progression through ubiquitination, revealing a potential therapeutic target in cancer.

Transposable temperate phages promote the evolution of divergent social strategies in Pseudomonas aeruginosa populations

This study shows transposable phages drive divergence in social strategies of Pseudomonas aeruginosa by promoting extreme siderophore production phenotypes in iron-limited environments.

Ecological selection of siderophore-producing microbial taxa in response to heavy metal contamination

The paper examines how heavy metal contamination influences siderophore production in microbial communities, finding increased production in contaminated environments.
