Breeding Timing Changing

Early Breeding Season for Some Arctic Seabirds Due to Global Warming,
University of Barcelona, October 7, 2019.

MAIN POINTS

Dramatic Changes
"The Arctic is one of the most sensitive areas to the global warming effects. Ice melting and the continuous rise of temperatures -higher than the average worldwide- are dramatically altering the structure of the Arctic ecosystems."

10 Days Earlier Breeding
Earlier Springs
"...surface-feeding seabirds in the north of the Pacific Ocean are moving their breeding season to an earlier timing than the rest of species -about ten days before for over the last thirty-five years- due the ocean's temperature rise and ice melting, which are signs of Spring onset in the Arctic."

The Arctic
Most Sensitive Environment
"In Arctic regions, the time period with optimal conditions for the reproduction of seabirds is quite limited."

Most Sensitive Inhabitants
"Birds, and specially seabirds, represent one of the most threatened taxonomic groups due the effects of global warming and the human activity impact (fishing, etc,). "

Narrow Arctic Window
"Arctic seabirds only reproduce during a particular time in Spring, when light and temperature conditions as well as food availability are optimal. However, this temporary window with optimal conditions does not last long, and if these animals are not able to adapt, they can fail when trying to reproduce"

"Regarding the Arctic birds, the changes we observe can have severe consequences in populations, especially if we think about the species with less abilities to adapt the environmental changes due global warming."

Contradictory Effects
"...not all evidence points out to the same direction. Sometimes we find results or evidence that could be contradictory."

"...some species that have not shown a response..."

"Changes in the breeding season seem less in species that dive to catch preys, such as the Atlantic puffin (Fratercula arctica), the rhinoceros auklet (Cerorhinca monocerata), the tufted puffin (Fratercula cirrhata), the horned puffin (Fratercula corniculata), and the crested auklet (Aethia cristatella)."

Nonetheless
"This can only mean there is still a lot to find out about how species respond to the environmental changes that are occurring and the consequences of these responses. Therefore, we have to take these changes, which are taking place in natural ecosystems in general and the arctic ones specifically, very seriously."

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!
