🍑My peach tree hasn't leafed out yet. In researching the matter, I learned about "Chill Hours." Chill hours are the accumulated hours of time spent below 45° & for fruit trees to be woken from #dormancy they require a particular amount of Chill Hours.

My #peach tree, for instance, requires 1100 #Chill Hours & this year it only got 850. Therefore, my peach tree is stuck in a semi-dormancy. This will delay growth by a couple of months. I'll eventually see leaves & fruit but they may be meager.

The London #plane (#Platanus × #hispanica) is frequently planted in major German cities due to its tolerance of urban climates, as seen here in park Rehberge, Berlin. Photos show the #fruit, a spherical cluster of nut-like achenes with wind dispersal. According to S. Zhang et al. (2019), three #FULlike #genes, PlacFL1/2/3, regulate flowering, #flowerdevelopment, and #dormancy.

"Researchers recently reported the discovery of a natural protein, named Balon, that can bring a cell’s production of new proteins to a screeching halt. Balon was found in bacteria that hibernate in Arctic permafrost, but it also seems to be made by many other organisms and may be an overlooked mechanism for dormancy throughout the tree of life."

Overall, these findings provide an explanation for the wide diversity in the physiological traits, ecological strategies, and #dormancy patterns of dormancy-capable endotherms! 😃

I am absolutely delighted to finally have this out and am looking forward to feedback! 4/4

In the present study, we performed a thorough #evolutionary analysis of the #dormancy capabilities of 737 mammalian and 601 avian species! We also compiled a dataset of 21 ecophysiological variables per species.

We show that:

➡️ daily torpor and hibernation are parts of a continuum rather than distinct dormancy states.

➡️ many ecophysiological variables correlate systematically with dormancy, but weakly so!

➡️ hibernation (and daily torpor) likely emerged multiple times in various lineages. 3/4

#Dormancy can be classified into 2 main types: daily torpor (lasting less than 24 hours) and #hibernation (lasting longer than that, up to multiple months).

To this day, we do not know if:

❓ these two types represent evolutionarily discrete states, or if they are parts of a continuum.

❓ dormancy capabilities can be accurately predicted from species' physiological traits or #ecological strategies.

❓ hibernation evolved once in #mammals (and #birds) or multiple times independently. 2/4

Many #endotherms 🦇🐦 respond to challenging environmental conditions (e.g., extreme temperatures 🌡️, low food availability) by entering #dormancy. That is, they greatly decrease their #MetabolicRate and body temperature and, by doing so, reduce their energy expenditure. 1/4

Second talk by Chris Gregg from UUtah, this time about #metabolism in disease. Excellent talk and nice to see some references to Anna Miller's work on tumor #dormancy . It was great seeing Chris and his work this week!

Leaf bud emergence on the "sprawlmonds" growing potted outside my trailer.

I took photos in the field as well, but these plants are so small it's much easier for me to get the right angle on things.

One of the brown bud scales on a dormant almond bud harvested in Nov. For scale, that's the tip of a bamboo skewer it's on.

More detailed file names and notes and photos during dissection means it takes even longer to get through a single dormant bud.

I wasn't happy with how the microscope cam didn't have the resolution to catch the light reflecting off these cells, so I switched to the iPhone. But I haven't mastered the after-market phone carriage yet so I haven't stacked the photos.

This is one of the outer bud scales of a dormant almond bud sampled last Nov.

What do you mean by inherent, innate, imposed, physical, physiological, morphological, primary, or secondary, ... dormancy?
How is dormancy released?
Is dormancy a bet-hedging strategy?

"While reviewing the literature on #fire-released #seed #dormancy (https://doi.org/10.1111/brv.12855) we became aware of limitations and disparities in current terminology ..." - Byron Lamont

So I helped Byron to make some clarification!

Does reduction of #seed #dormancy during ex situ cultivation affect #germination and establishment of #plants reintroduced into the wild?

https://besjournals.onlinelibrary.wiley.com/doi/abs/10.1111/1365-2664.14354

Interesting @JAppliedEcology paper by Ensslin et al. exploring this for Digitalis lutea. They show this can apply and can negatively affect outcomes. They conclude plant material from wild populations is best suited for #restoration, but perhaps another option may be to regularly refresh ex situ cultivations with wild source material?
