A Cold Stress‐Activated Endocrine Sentinel Chemical Hormone Promotes Insect Survival via Mitochondrial Adaptations Through the Adipokinetic Hormone Receptor

open access: yesAdvanced Science, EarlyView.
Seasonal cold adaptation is vital for insect survival, yet the molecular mechanisms linking diapause to mitochondrial resilience remain largely unresolved. We identify ascaroside C9 (asc‐C9) as a key endocrine signal that enhances diapause survival during cold stress by activating the AKHR–PGC1α–UCP4 axis, thereby driving cold‐induced lipolysis and ...

The effect of methionine and folic acid administered in ovo on the hematological parameters of chickens (Gallus gallus domesticus)

open access: yesPoultry Science, 2020
Methionine (Met), an essential amino acid in poultry diets, when overdosed may cause hyperhomocysteinemia, which is mainly a trigger for cardiovascular diseases in humans.

The impact of fire on habitat use by the short-snouted elephant shrew ('Elephantulus brachyrhynchus') in North West Province, South Africa [PDF]

open access: yes, 2008
Several studies have investigated the response of small mammal populations to fire, but few have investigated behavioural responses to habitat modification. In this study we investigated the impact of fire on home range, habitat use and activity patterns

Genomics Insights Into High‐Latitude Adaptation of Tibetan Macaques

open access: yesAdvanced Science, EarlyView.
Tibetan macaques exhibit unique adaptations to cold, high‐latitude environments, including shortened tails and enhanced fat storage. Genomic analyses reveal a species‐specific TBX6 mutation linked to tail reduction and selection on lipid metabolism genes.

Arctic introgression and chromatin regulation facilitated rapid Qinghai-Tibet Plateau colonization by an avian predator

open access: yesNature Communications, 2022
The Qinghai-Tibet Plateau is as cold as the Arctic, but presents unique hypoxia and high ultraviolet conditions. Here the authors find that gene flow from Arctic gyrfalcons aids plateau saker falcons’ cold adaptation, and independent non-coding genomic ...

Lipid Droplet‐Localized Spindle Apparatus Coiled‐Coil Protein 1 Regulates Lipid Droplet Distribution

open access: yesAdvanced Science, EarlyView.
SPDL1‐L, a long isoform of SPDL1, is identified as a bona fide lipid droplet‐associated protein that acts as a dynein adaptor to drive perinuclear clustering of lipid droplets. By linking lipid droplets to the microtubule network, SPDL1‐L extends the function of SPDL1 beyond mitosis and contributes to lipid droplet organization and nuclear remodeling ...

Variation in plasma oxidative status and testosterone level in relation to egg-eviction effort and age of brood-parasitic common cuckoo nestlings [PDF]

open access: yes, 2012
To avoid competition for parental care, brood-parasitic Common Cuckoo (Cuculus canorus) nestlings evict all of the host's eggs and nestlings within a few days after hatching.

The Gut Microbiota Regulates Motor Deficits via Butyrate in a Gnal+/− Mouse Model of DYT25 Dystonia

open access: yesAdvanced Science, EarlyView.
The present study provides compelling evidence for a modulatory role of the gut microbiota in the pathology of DYT25 dystonia, and butyrate supplementation alleviates the motor deficits of dystonia in Gnal+/− mice. Abstract Dystonia is the third most common movement disorder, following essential tremor and Parkinson's disease. The underlying mechanisms
