Changing Timing of Life Bleeding Fertility Out of Nature

Early arrival of spring disrupts the mutualism between plants and pollinators,
Hokkaido University, July 12, 2019.

MAIN POINTS

Bummer for Jap Bumblers & Flowers…
"...demonstrated that early snowmelt results in the spring ephemeral Corydalis ambigua flowering ahead of the emergence of its pollinator, the bumblebee."

The Situation
"Global warming has affected the phenology of diverse organisms, such as the timing of plant flowering and leafing, animal hibernation and migration. This is particularly so in cold ecosystems, increasing the risk of disturbing mutual relationships between living organisms. It could also affect the relationship between plants and insects that carry pollen, but few studies have been conducted and the subject remains largely unknown." (We explore recent research through the links below...)

Natural Perfection
"The researchers examined Corydailis ambigua growing in cold-temperature forests in Hokkaido in northern Japan, and bumblebees, which collect nectar from the flowers. Usually the bloom of the flowers and emergence of the bumblebees are in sync."

Damn!
"They monitored the plant and insect for 19 years in a natural forest of Hokkaido..."

The, "...bumblebees, which hibernate underground during winter..."

Study Proves…
"When the snowmelt is early, flowering tends to occur before the bees emerge, creating a mismatch. The wider the mismatch, the lower the seed-set rate due to insufficient pollination."

Mismatch
"Studying how this phenological mismatch will affect the reproduction and survival of plants and insects could give us clues to the larger question of how global warming is affecting the overall ecosystem."

 

Bottom Line

This mismatch driven by our unbalancing climate, weather, and ecosystems is typical of the changes we can see lobotomizing Nature all around the Northern Hemisphere...

 

Definition of Phenology

"Phenology is a key component of life on earth. Many birds time their nesting so that eggs hatch when insects are available to feed nestlings. Likewise, insect emergence is often synchronized with leaf out in host plants. For people, earlier flowering means earlier allergies. Farmers and gardeners need to know the schedule of plant and insect development to decide when to apply fertilizers and pesticides and when to plant to avoid frosts. Phenology influences the abundance and distribution of organisms, ecosystem services, food webs, and global cycles of water and carbon. In turn, phenology may be altered by changes in temperature and precipitation.

Changes in phenological events like flowering and animal migration are among the most sensitive biological responses to climate change. Across the world, many spring events are occurring earlier—and fall events are happening later—than they did in the past. However, not all species are changing at the same rate or direction, leading to mismatches. How plants and animals respond can help us predict whether their populations will grow or shrink – making phenology a “leading indicator” of climate change impacts."

An American Bumbler in Jack Main Canyon, Just to compare with the Jap Bumbler... The Jap Bumbler looks smooth & refined, compared to the rough look of this American Dude... This sucker was scraping layers of salt off my skin, balling it up, and stashing it. It tickled.

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

I NEED HELP!
If you feel these efforts are valuable, I'm cordially inviting you to support them, here:

 

 

I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
