Microbial Endolithic Community at Meteor Crater

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Postimpact recovery and evolution in response to climate changes produced a modern ecosystem at Meteor Crater dominated by a grassland and woodland of piñon and juniper, which has been used to evaluate floral and megafaunal consequences of impact cratering during the Phanerozoic Eon of complex life.

Comparative efficacy and studies of mode of action of minerals from diatoms against three species of filth flies

open access: yesMedical and Veterinary Entomology, EarlyView.
Mortality for diatomaceous earth was observed as early as 2 h after exposure with 50% and 90% mortality at 3.5 and 4.6 h (LT50 and LT90, respectively) for Musca domestica. The LT50 and LT90 increased when the size of the fly species increased (M. domestica to Cochliomyia macellaria to Sarcophaga bullata) and increased for all three from 50 to 70 ...

The unicellular green microalga Botryosphaerella sudetica links plant‐like light protection with an algal lifestyle

open access: yesNew Phytologist, EarlyView.
Summary Nonphotochemical quenching (NPQ) mechanisms fine‐tune light utilisation in the photosynthetic antenna, for example, in response to excess light, to prevent photodamage. NPQ comprises distinct mechanisms, all contributing to photoprotection but acting on different time scales.

Role of extracellular carbonic anhydrase in the polar diatom Fragilariopsis cylindrus

open access: yesNew Phytologist, EarlyView.
Summary Diatoms are major primary producers in productive polar oceans, where cold temperatures and high CO2 solubility raise questions as to whether they rely on the CO2‐concentrating mechanism (CCM) to saturate photosynthesis. Knowledge of CCM function will help better predict the sensitivity of diatom primary production to warming and acidifying ...
