The toxin–antitoxin complex Fic‐1–AntF functions as a deAMPylase that regulates the activity of DNA gyrase

mLife, EarlyView.
Abstract Toxin–antitoxin (TA) systems found in diverse bacteria play important roles in their adaptation to changing environments. The toxin of the Fic‐1–AntF TA pair from Pseudomonas bijieensis strain 2P24 inhibits bacterial DNA replication by attacking the subunit B of DNA gyrase (GyrB) via AMPylation, while the antitoxin AntF blocks its enzymatic ...

Diet and Oral Health of Scythian Populations in Ukraine (700–200 bce): Evidence for Grain Consumption and Food Processing

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT We examined whether Scythian‐era populations living in different ecological zones had distinctive oral health patterns during the Iron Age. Our interdisciplinary approach should clarify whether these populations had different diets or behavioral practices.

The dominance of non‐native plants over native plants increases with the number of global change factors

Oikos, EarlyView.
Global environmental change and plant invasion are both recognized as key indicators of the Anthropocene. Still, how the number of co‐acting global change factors (GCFs) influence invaded plant communities remains unclear, even though in nature GCFs usually act together rather than alone.

Benthic megafauna and the functioning of macroalgal forests and urchin barrens

Oikos, EarlyView.
Two temperate rocky reef food‐web models, representing the trophic diversity of the Mediterranean rocky reef communities, were built for the two stable states: macroalgal forests and barren grounds, which are characterized by opposite amounts of erect macroalgal biomass.

Understanding the effects of patch‐burn grazing management on aboveground grassland invertebrate biodiversity

Oikos, EarlyView.
Landscape heterogeneity is widely recognized as a driver of biodiversity, yet its consequences for above‐ground, foliage‐dwelling insect communities under active grassland management remain underexplored. Patch‐burn grazing (PBG), which rotates fire across patches within a grazed landscape, is designed to promote spatial and temporal heterogeneity by ...
