Heat acclimation mediates cellular protection via HSP70 stabilization of HIF-1α protein in extreme environments.

Heat acclimation (HA) is an evolutionarily conserved trait that enhances tolerance to novel stressors by inducing heat shock proteins (HSPs). However, the molecular mechanisms underlying this phenomenon remain elusive. In this study, we established a HA mouse model through intermittent heat stimulation.

Background: Global climate change significantly impacts ecosystems, particularly through temperature fluctuations that affect insect physiology and behavior. As poikilotherms, insect pests such as the globally devastating diamondback moth (DBM), Plutella xylostella, are especially vulnerable to rising temperatures and extreme heat events, necessitating effective adaptive mechanisms.
Results: Here we demonstrate the roles of zinc finger proteins (ZFPs) in mediating thermal adaptability in DBM.
Comprehensive genomic and phenotypic characterization of thermophilic bacterium Sinimarinibacterium thermocellulolyticum sp. nov. HSW-8, a cellulase-producing bacterium isolated from hot spring water in South Korea.

A thermophilic cellulase-producing bacterium, strain HSW-8, isolated from hot spring waters in South Korea, was subjected to a taxonomic analysis. Cells of strain HSW-8 were gram-stain-negative, facultatively anaerobic, rod-shaped, with optimum growth at 45 °C, pH 7.0, in the presence of 0% (w/v) NaCl.

The sustainability of livestock systems is widely acknowledged to be threatened by climate change on a worldwide scale. There are worries about the effects this phenomenon may have on the productivity and performance of native livestock species due to its influence on environmental stresses, such as the frequency and severity of unfavorable weather occurrences and the ongoing changes in the agro-ecological landscape. Among the most climatically tolerant livestock animals, goats can survive in a range of environments, from deserts to alpine areas.

Compound soil drought and heat extremes are expected to occur more frequently with global warming, causing wide-ranging socio-ecological repercussions. Vegetation modulates air temperature and soil moisture through biophysical processes, thereby influencing the occurrence of such extremes. Global vegetation cover is broadly expected to increase under climate change, but it remains unclear whether vegetation greening will alleviate or aggravate future increases in compound soil drought-heat events.
