SnapShot: Microbial Extremophiles

open access: yesCell, 2020
Extremophiles are remarkable examples of life's resilience, thriving in hot springs at boiling temperatures, in brine lakes saturated with salt, and in the driest deserts. We review the biogeography, currently known limits of life, and molecular adaptations to extremes. See the online interactive map for additional detail on biogeography, environmental

Casanovas are liars : behavioral syndromes, sperm competition risk, and the evolution of deceptive male mating behavior in live-bearing fishes [version 2; referees: 2 approved, 1 approved with reservations] [PDF]

open access: yes, 2013
Male reproductive biology can by characterized through competition over mates as well as mate choice. Multiple mating and male mate choice copying, especially in internally fertilizing species, set the stage for increased sperm competition, i.e., sperm ...

The extremophile Picrophilus torridus carries a DNA adenine methylase M.PtoI that is part of a Type I restriction-modification system

open access: yesFrontiers in Microbiology, 2023
DNA methylation events mediated by orphan methyltransferases modulate various cellular processes like replication, repair and transcription. Bacteria and archaea also harbor DNA methyltransferases that are part of restriction-modification systems, which ...
