Climate Change Reduces Forest Regrowth After Wildfires

Forest are struggling to comeback after wildfires, but does anyone know why? A research team discovered climate change may be straining young saplings’ abilities to reestablish themselves after a wildfire. A warmer and drier climate does not provide the right temperature or water resources a sapling needs to regrow a forest. With wildfires growing larger and more intense, this issue needs to be addressed and extinguished to sustain our forests!

George Washington: General, Founding Father, and … Ecologist?

Before George Washington became the military general and Founding Father we know today, he spent years traveling the wilderness and helping divide up land for colonial settlement. His meticulous notes about the natural landscapes have been preserved over time because of his later prominence as a political figure. Today, these documents can be used to reconstruct what forests looked like over 250 years ago.

How Pre-Industrial Charcoal Changed the Soils Under Our Feet

Tragically, when some people look at the soil beneath our feet, they only see ‘dirt’. They are missing the fact that soils contribute so much to nature and our lives. But, what happens when humans alter soils from their natural state? Researchers from Cottbus, Germany, aimed to find out how charcoal production in the Northeastern US during the mid 1800s impacted the soils and ecology of the forests that we see today. Surprisingly, the answer is a little bit below the surface.

Evidence from the sediment: Lake Baikal diatom community changes in response to shifting environmental conditions

Located in Siberia, Russia, Lake Baikal is the deepest lake in the world (Figure 1). Similar to other waterbodies around the world, both big and small, Lake Baikal is exhibiting changes in the community composition of its primary producers in response to climate change induced changes in surface temperatures and nutrient inputs. In this study, scientists examine community composition shifts in a group of primary producers known as diatoms and examine the influence of climate change on this shift.

Is there space for nature in man-made jungle?

We humans are responsible for not just shaping existing environments, but for creating new ones as well. Urban and industrial areas can sometimes be seen as “unnatural” but new research has shown that a ton of new species want to be neighbors. On top of that- they’re thriving. Read on to learn more!

Alaskan Megathrust Earthquakes: Sedimentary records provide new data and a look 2000 years into the past

In 1964, a historically unprecedented magnitude 9.2 earthquake struck the Aleutian Islands of Alaska. The earthquake prompted scientists to figure out that the Aleutians lie along a unique form of fault, now known as a “megathrust” fault. During a megathrust earthquake, large swaths of land suddenly rise or sink, depending on their location relative to the fault rupture. Over long periods of time, as tectonic plates slide under one another, compression causes the top plate to buckle and rise up along the coast. When enough energy is accumulated, a slip eventually occurs. In places that were being uplifted, the land suddenly falls a few meters as the strain is released, otherwise known as an earthquake. It has been thought that areas of uplift and subsidence remain constant, always rising or falling in exactly the same place with every earthquake. However, a recent study suggests that these areas are not constant, further complicating our understanding of how “megathrust” earthquakes occur.

津波: The Story of the Wave

If you’re lucky, there are five minutes between when a tsunami alarm sounds and when the wave hits. Too often those five minutes are not enough, and the fate of a coastline is at the tsunami’s mercy. Understanding tsunami cause and occurrence is vital for coastal communities. Read on to learn more about tsunami records and how they play a role in shaping natural disaster planning.

What’s driving changes in cod spawning grounds: climate or fishing?

Northeast Arctic Cod perform seasonal migrations from their feeding grounds to their spawning grounds. Recent evidence suggests that the distribution of cod between spawning grounds is changing. Two hypotheses have been proposed to explain why fish spawning grounds are changing: climate and fishing pressure. In order to determine which of these hypotheses may be the driving force in changing Northeast Arctic Cod populations, a team of scientist from Europe investigated fishery data from 2008-2016. Their results suggests that climate is driving changes in the distribution of Northeast Arctic cod spawning grounds.

Soil in the Succotash Marsh, Rhode Island: Coring for clues to past coastal storms

When you think of a saltmarsh, what comes to mind? Maybe a place that smells bad and you prefer to avoid? A place to fish? Turns out, salt marshes hold clues to the past. Scientists along the East Coast of the United States, for example, can use the information in salt marsh soils to reconstruct past storms and determine the past sea levels. As scientists in Rhode Island, we were able to easily try and replicate the findings of a previously published study from the Succotash Marsh also located in Rhode Island.

Seeing the Forest for the Trees

Satellites have changed our ability to see the globe. We can now use satellite data is to monitor change in the amount of land covered by forests, and determine the reasons for that change. In this article, we discuss recent findings global forest monitoring and the impact of supply chain decisions by corporate actors.
