Researchers have identified the specific neural pathway through which the brain's circadian clock times and controls "torpor," a natural, reversible state of reduced body temperature and metabolism utilized by certain mammals to survive severe environmental stress.

Medaka fish kept in semi-natural outdoor environments experience reproductive clocks that are significantly out of sync with those kept in laboratory conditions, ovulating approximately 3.5 hours earlier.

The complete annual life cycle of the red-necked nightjar—including feeding, migration, and breeding—is strictly synchronized with the 29-day lunar cycle due to its reliance on moonlight for energy acquisition.

Researchers reproduced the simplest natural #circadian system found in blue-green algae (#cyanobacteria ) within a test tube, demonstrating how a single clock signal coordinates daily #gene switching.

🌅 Within you, billions of molecular clocks tick in coordinated patterns. From 90-minute sleep cycles to seasonal patterns in gene activity, your body orchestrates time across every scale.

Did you know your liver, heart, and skin each have their own circadian timing? ⚙️

@GrrlScientist - ooooh, gene expression and TIME! Disturbed by this while writing up my PhD in 1983 but there was so little to hold onto, back then (and I was supposed to be pinning decision to differentiation onto a phase of cell division, oooof). Sounds like there's not much more to grab nowadays, but wow what a fab field of study #Chronobiology

Anyone working in #agriculture knows how important #timing is, but did you know that plants have internal #rhythmic biological mechanisms that can influence the effectiveness of #agrochemical applications depending on the time of day?

Understanding these mechanisms and how to apply this knowledge in the field is still a challenge. Together with Carlos Hotta and Antony Dodd, we decided to present some ideas in this new article published in The New Phytologist Foundation—my first as first author. ✨

I’m very excited to share these ideas because they’re part of the topic of my doctoral thesis, which focuses on #plant sensitivity to #herbicides at different times of the day.

#Chronobiology is a relatively recent science, but its discoveries have already earned a Nobel Prize in 2017. Personally, I believe that studies in chronobiology applied to agriculture could lead to the emergence of a new scientific field: #chronoagronomy.

Chronoagronomy could focus on studying the effects of time in agriculture—understanding all temporal factors and how they affect production systems, from soil preparation and crop rotations to the final product price in the market—with the goal of optimizing outcomes through process synchronization and the application of #chronoculture or circadian agriculture.

#Agronomy has always relied on knowledge of temporal factors, but has never studied them systematically in all their dimensions. Understanding the role of #time might be the breakthrough we need to produce more, produce better, and avoid environmental disaster.

"We report clear associations between circadian gene expression, daily behavioral patterns, and fitness in free-living, urban-adapted individuals. The dose-dependent nature of the observed behavioral and genetic changes supports #UrbanPlanning measures, such as the reduction of #ALAN intensities to a level that preserves wildlife health."

Hm, also learning about the nasal cycle.

"The nasal cycle is the subconscious alternating partial congestion and decongestion of the nasal cavities in humans and other animals.

[...]

This cycle, which is controlled by the autonomic nervous system, has a mean duration of two and a half hours but varies widely with age, body-posture, and other conditions."

Phenology (Climatology 🌍)

Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors. Examples include the date of emergence of leaves and flowers, the first flight of butterflies, the first appearance of migratory birds, the date of leaf colouring and...
