The phrase "age transitions" is correct and usable in written English.
It can be used to refer to the changes or shifts that occur at different stages of life, often in discussions about development or aging.
Example: "Understanding age transitions is crucial for developing effective educational programs tailored to different life stages."
Alternatives: "life stage changes" or "developmental transitions".
The pollen record has allowed us to relate two cultural periods of changing, the Copper Age Early Bronze Age and Late Bronze Age Early Iron Age transitions, to abrupt climate disruptions, the so-called 4.2 and 2.8 ka cal BP events respectively.
To obtain homogeneous age transitions throughout the simulated period, initial week-ages are randomly assigned between 1 and 52.
Previous studies have highlighted social roles and age transitions to understand the impact of health on activity participation [ 49– 52].
In contrast, in male brains, only 5.4% of genes were significantly altered at this age transition.
The two erosive events, which reflect centennial-scale changes in the aggradation/degradation ratio, are chronologically constrained to the Eneolithic Bronze age transition (~ 3800 cal yr BP) and to the Bronze Iron age transition (2900 2800 cal yr BP), respectively.
Ants change careers as they age, transitioning from caretakers to cleaners and then foragers, according to a new study that tracked more than 1,000 ants for 41 days.
This is in stark contrast to several other pollen studies from the Bjäre Peninsula that record widespread woodland clearance and agricultural activity from the late Neolithic Bronze Age transition.
This 'regressive' trend, reflecting coastal progradation under nearly stable sea-level conditions, was interrupted by widespread swamp development close to the Iron Etruscan age transition.
We're already warming the Earth about 20 times faster than during the ice age transition, and over the next century that rate could increase to 50 times faster or more.
The last ice age transition saw about 4°C global warming over 10,000 years; humans are on pace to cause that much warming between 1900 and 2100 – a period of just 200 years, with most of that warming happening since 1975.
If we follow through with the Paris agreement and manage to limit global warming to 2°C over a 200-year period, in that best-case scenario the Earth would still warm 20 times faster than a natural ice age transition.
