Remote Environments – envirobites

As you swim through a coral reef, you see parrot fish, clams and other colorful aquatic creatures swimming elegantly and going about their lives. While you, with your snorkel, are confined to the surface of the water and the occasional dive for as long and as deep as you can hold your breath, the fish “breathe” easily with their gills (or lungs in the cases of some evolutionarily interesting fish). But do they breathe that easily? Living in and getting oxygen from a high-pressure aquatic environment is difficult and metabolically demanding, and some fish have found special ways to make it easier.

Bring on the (prescribed) fire!!!

April 29, 2020April 29, 2020 Luiza Aparecido 0 Comments

Prescribed burns should be applied not only to avoid uncontrolled wildfires, but also to maintain open vegetation types and their biodiversity as fundamental pieces of savannas and grasslands, threatened by fire suppression or modified fire regimes. (Modified from Durigan et al. (2020))

Buried beneath the streambed is another environment home to a population of bugs more important to their local streams than ever before thought!

Unleashing Pollutants: Environmental Fate of Antarctica In a Warmer World

February 7, 2020 Anita Masse 0 Comments Antarctica, Climate Change, Global Warming, Pollution

Antarctica has been a depository for pollutants for decades. The brutal cold has kept them dormant and unable to inflict harmful effects on nature. As temperatures rise and ice melts, what is the fate of these pollutants in this unique landscape?

Fire Refugia are Critical for Conserving Biodiversity

January 25, 2020 Andrew Barton 0 Comments

“Fire refugia are landscape elements that remain unburned or minimally affected by fire, thereby supporting postfire ecosystem function, biodiversity, and resilience to disturbances.” (Meddens et al. 2018)

The Sound of Silence: Consequences of Man-made Noise on Humpback Whale Songs

May 24, 2019March 19, 2020 Laura Schifman 0 Comments BSC4052, marine systems, noise, noise pollution, whales

Male humpback whales sing loudly and for long durations during breeding season. A hundred years ago their voices did not have to compete with much man-made noise. These days they contend with underwater drilling, sonar, and the noise of thousands of cargo and passenger ships. This affects how and when they sing. The consequences of these changes are still largely unknown.

Voyage to Iceberg Alley

April 1, 2019April 4, 2019 Marlo Garnsworthy 0 Comments Antarctica, Ice Sheets, Iceberg Alley, icebergs, Pine Island Glacier, sea level rise, Southern Ocean, Thwaites Glacier

A couple of days ago, right around sunrise, we sailed out of the Straits of Magellan and into the southern Atlantic Ocean, bound for the Southern Ocean and the Antarctic waters known as Iceberg Alley. Giant petrels soared against a clear blue sky, and gentle waves rocked the ship—although we didn’t expect that to last! I am aboard the JOIDES Resolution, a research vessel and drilling ship, and we are intentionally sailing into some of the planet’s wildest seas and the area of greatest iceberg concentration in the Antarctic.

Animal Depopulation Due to Armed Conflict Can Drastically Alter Ecosystems For Decades

Armed conflict is one of the least-studied human activities that drastically affect the environment. A recent paper looks into the major changes in animal population patterns in Mozambique following decades of devastating war.

What gives glacier algae their wild colors?

March 21, 2019March 24, 2019 Abigail Lewis 0 Comments algae, color, sea level rise, snow

When a British expedition reported seeing pink mountain snow in 1818, the London Times said: “Our credulity is put to an extreme test upon this occasion, but we cannot learn that there is any reason to doubt the fact as stated.” Two hundred years later, we now can confirm that pink snow (“watermelon snow”) is real and it is caused by certain types of algae. But why is it that snow algae take on such distinctive red and purple colors? And how does this connect to melting glaciers or global sea level rise?

The Five Deeps Expedition: The first attempt to dive to the deepest point in five oceans

January 5, 2019January 6, 2019 Maddie Halloran 0 Comments Ocean

The Five Deeps Expedition is led by Victor Vescovo, an American attempting to visit the five deepest areas of the ocean in a manned submersible. In December of 2018, he became the first human to reach the bottom of the Puerto Rico Trench in the Atlantic Ocean. Read on to learn more about this expedition, and keep an eye out for the results of the remaining four dives in 2019!
