Duck broods are more resilient than expected in the face of oil and natural gas extraction

The Bakken Formation, a unique geological feature in the midwestern US and Canada, is a mecca for oil reserves and duck habitat. Scientists aimed to better understand how increased oil production has impacted the establishment and survival of duck broods.

Which Wetland? National Dataset Helps Reduce Flood Risk

Flooding is an expensive and dangerous problem across the globe. Freshwater wetlands can help reduce flood risk and damage. During large storm events, wetlands hold extra water allowing it more time to flow downstream or into the soil. In order to help communities understand where to spend their time and resources to utilize these important landscape features, researchers created a national dataset that identifies the wetlands that would be best for mitigating flood risk.

Trees, Tempests, and Time: What trees can tell us about weather in the past

For storms along the Gulf Coast, first-person recordings are only reliable for the past 150 years. But knowing more about when storms happened in the past helps us understand how the climate is changing and how to reduce storm risks for coastal communities. To do that, we have to use even more unusual records: tree rings.

Preserving Culturally-Important Xochimilco Wetlands Requires Policy and Personal Change

Created by the Aztecs in 500 CE for agriculture, Xochimilco is an area of culturally important wetlands in southern Mexico City. Despite its cultural and economic importance, this area is experiencing wetland degradation and loss due to urban development and water quality issues. Even with a high level of local concern about wetland degradation, little effort will be made toward conservation without a change in public policies regarding local infrastructure and development.

Growing Conditions Improve with a Pinch

Salt marshes are full of crustacean inhabitants. In particular, fiddler crabs and purple marsh crabs of New England modify these coastal ecosystems by burrowing beneath the waterlogged soils, chewing up plants, and increasing nutrient exchange rates. But it is uncertain to what extent each species contributes to the modification of a salt marsh. Research by Alexandria Moore found the presence of crabs had a significant effect on multiple aspects of salt marsh health and that the herbivore, purple marsh crab, modifies salt marsh ecosystems beyond eating plants.

Where the mangrove grows

A 65 meter tall mangrove. Imagine that. A tree growing in saltwater that is 20 stories tall. Considering the only mangroves I have seen look like shrubs, I couldn’t believe that some mangroves could reach such heights. But then I saw some photos on Twitter and talked with a scientist who is using new technology to estimate the enormous amount of carbon stored by these beastly coastal trees. Mind Blown.

Sinking Rails

Coastlines and estuaries are often densely populated with a wide diversity of birds. Many species have adapted to the salty coast and thrive in its waves, beaches and marshes. However, sea-level rise is changing the coast. Researchers, representatives from both universities and governmental agencies of southern California collaborated to predict what habitat for the Ridgway’s rail may look like in the next ten, twenty, thirty years all the way until the year 2110 with several predicted rates of sea-level rise. As sea levels increase, more habitat may become available; but too much flooding could destroy habitat as well.
