Astonishing Photo of Millions of Monarch Butterflies Wins 2024 European Wildlife Photographer of the Year Contest – Starting out the gleanings list this week with beautiful images from nature.

Iceberg A-68: The story of how a mega-berg transformed the ocean - Scientists following A-68's birth and demise were able to track just what such giant icebergs do to the surrounding ocean. For its short, transient life as an iceberg, A-68 became a frozen lifeboat for a wide range of species. Over its three-and-a-half-year journey since it broke away from the Antarctic ice shelf, A-68 lost 802 billion tons of ice as it thinned from an average thickness of 770ft (235m) to 551ft (168m). Over a three-month period at the end of 2020 and start of 2021, it dumped an estimated 152 billion tons of fresh water into the ocean – that is equivalent to almost 61 million Olympic-sized swimming pools. At the peak of its breakup, around 1.5 billion tons of fresh water was gushing into the ocean every day. The crushing weight of the freshwater from A-68a as it melted may have helped force carbon-based material down more quickly, to depths where it was less likely to be eaten.

Salmon Make a Long-Awaited Return to the Klamath River for the First Time in 112 Years, After Largest Dam Removal in U.S. – Four dams blocked the salmon’s migration between the Klamath basin and the Pacific Ocean…but now the dams have been removed, and the fish are returning. The first salmon in the river since 1912 were spotted less than two months after the last dam was removed.

Avian architects: weaver birds in Africa have unique building styles – The African white-browed sparrow weavers build nests that look like pompoms in acacia trees. Some families build roosts that are very long, with long entrance and exit tubes; others will build roosts that are much shorter, with hardly any tubes. Essentially, it looks like different white-browed sparrow weaver families have different architectural styles. Researchers excluded all environmental and genetic explanations for the differences in the structures built by different families. Maybe, like humans, some species of birds have their own architectural traditions passed on across generations through social interactions.

Huge! A Roman Engineering Marvel Reaching Across a Spanish City - In Segovia, the Romans built an aqueduct that stands as arguably their greatest architectural legacy from six centuries in Spain. After drawing water from the Frio River, the aqueduct runs underground for some 10 miles before appearing in Segovia as a grand, elegant beast that strides for nearly 2,400-feet across the town. Comprised of more than 20,000 blocks of granite and erected without a lick of mortar, at its highest point the aqueduct reaches more than 90-feet high with narrow, double arches. It remained in use until the late 1970s.

Life-saving spongelike 'bandage' rapidly stops hemorrhaging and mitigates risk of infection - A liquid gel comprised of siloxanes (silicon and oxygen) that is delivered via a special two-chamber syringe which rapidly expands into a spongy foam upon exposure to each other within the wound in under one minute. The sponge applies pressure to restrict the hemorrhage at the delivery site while also serving as an antibacterial agent because of the silver oxide in it.

Learning in the Environment: The Importance of Expanding Outdoor Education Across the United States - Although environmental discussions are expanding in schools, students often lack the opportunity to interact with the natural world through outdoor education, including place-based learning located in nature. The widespread decline of green spaces, especially in densely populated areas, restricts youth engagement with the environment. Interacting with the outdoors helps students to understand not only the environment itself but the role they can play in protecting it.

Chickpeas: Sustainable and climate-friendly foods of the future - Chickpeas are a drought-resistant legume plant with a high protein content that can complement grain cultivation systems even in urban areas. I have discovered that roasted chickpeas is my favorite ‘crunch’ topping for soups and salads!

Photo Contest Celebrates Excellence in Architectural Photography – I haven’t done much architectural photography…but maybe it is something to consider…when I am not able to do nature photography (which is my favorite).

Grasslands live in the climate change fast lane - The rapid shifts in grassland communities involve not only the gain of some hotter, drier species but also the loss of some cooler, wetter species. These shifts might have negative consequences such as dominance by non-native species and loss of biodiversity.

Gleanings of the Week Ending December 9, 2023

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Restored Glass Negatives Capture Daily Life in 19th-Century New England – Photographs taken from the 1860s to 1930s….Massachusetts…different photographers.

As Temperatures Rise, Dengue Fever Spreads and Cases Rise – The mosquitos that carry dengue viruses are extending their range. There were 0.5 million cases in 2000…5.2 million in 2019. In recent years, dengue has popped up in places it had never been seen, including Afghanistan, parts of Southern Europe, and, this year, Chad. An additional 2 billion people would be at risk of dengue exposure by 2080, compared to 2015. Areas unfamiliar with dengue may be hard hit even if case numbers aren’t high as people won’t have immunity from previous exposure to the virus, and public health systems may not be strong enough to cope with dengue outbreaks.

The World’s Largest Iceberg Is Drifting Three Miles Into the Ocean Each Day - The world’s largest iceberg, which had been grounded on the seafloor since the mid-1980s, is moving away from Antarctica and picking up speed. It could disrupt the foraging of seals, penguins and other seabirds. Called A23a, the iceberg measures around 1,500 square miles—more than 20 times the size of Washington, D.C.—and it’s roughly 1,300 feet thick, making it two and one-third times the height of the Washington Monument. It weighs nearly one trillion metric tons.

Landscape Photography Awards Rewards Authenticity in Photography – My favorite was “Little Leaves”….maybe because it didn’t have time to see a lot with fall foliage this year.

Expansive Alexander Calder Exhibition Opens in Seattle – Take a look at the museum’s site for the exhibit at well.

Bird Photography Contest Celebrates the Unique Diversity of Australia’s Wildlife - Nine winners were singled out for their work, rising above more than 6,000 images that were submitted. My favorite of this group is “Jambalaya on the Bayou.”

Volcano Monitoring Can Be A Risky Business: How Scientists Work Safely - Common PPE used in the field by HVO staff include respirators to filter volcanic gases, gas badges to monitor sulfur dioxide (SO2) concentrations, along with helmets and eye protection.  When molten lava sampling, crews will carry a face shield, fire-resistant clothing, and gloves to protect the wearer from radiating heat.

Best of 2023: Top 42 Photographs From Around the World – I have two favorites in this group of photos: the bald eagles and the dancing mantises!

African Penguins Tell Each Other Apart by Their Polka Dot Patterns – Evidently the chest plumage is unique to each bird….and the birds recognize the dots of their partners!

Photographer Chronicles the Enchanting Life of a Wild Red Fox for 8 Months – A Hungarian photographer’s project at his cottage in the forest after he noticed a fox running under the window one night.
