Historical Mercury Pollution: Tree Rings Have the Receipts!

Mercury is a troublesome pollutant in the environment and while we know a lot more about where sources are today, we don’t know as much about where sources were in the past and how high pollution levels were. Luckily, trees can help us to figure that out! Using traces of mercury pollution stored in tree rings, scientists try to see how mercury pollution levels have changed as we’ve become more industrialized.

The Noble Sea Sponge and its Role in Global Carbon Cycling

Global cycling of chemicals and nutrients like nitrogen, phosphorus, and silicon (Si) drive one of the most important biological processes on our planet, primary production and the removal of carbon from our atmosphere. What happens when the largest carbon and silicon sink isn’t actually as big as scientists originally thought? Chemical oceanographers Manuel Maldonado and his colleagues have come up with a new way to study the oceans most important chemical cycles and the surprisingly important role of the simple sea sponge.

It Makes “Cents”: Generating Renewable Electricity Benefits Health and Climate

Replacing fossil fuel electricity generation with renewable technologies has measurable benefits to human health and the climate. Researchers recently developed a simulation tool that reveals benefits are higher in certain regions of the US than others. Read more to see where deploying renewables would have the biggest impact!

It’s all in the genes: how water pollution keeps silver carp at bay.

Silver carp are a notorious invasive fish that are spreading throughout the Mississippi River Basin. Despite their rapid-fire range expansion, silver carp have yet to make it to the Great Lakes. A recent study explores the possibility that polluted Chicago-area waters may be preventing the spread of silver carp into Lake Michigan and beyond.

What is “dark diversity” and how can we use it to guide conservation and restoration?

The core of ecology is devoted to studying the interactions among species and their environment. But why are some species present and others absent in an environment? Think of a region of forest that has been converted to an agricultural field. The species that were thriving in the forest now have become absent because they are not tolerant of the new environmental conditions imposed upon them in the agricultural field.

Only a subset of all species in a region can tolerate the ecological conditions of a given site (the site-specific species pool). Of those, not all are realized in the local species pool. These absent species form what is called the dark diversity of a community. Authors Lewis et al. (2017) believe that the dark diversity concept can be used to complement and further develop conservation prioritization and management decision

Teenagers feel less connected to nature than children and adults, study finds

Understanding trends about how connected to nature different age groups typically feel is critical because it could potentially help target conservation efforts in the future. If certain groups are losing connection to nature, how can educators or policymakers intervene to counteract that? If there is an age where connection to nature tends to increase, how can conservationists reinforce that trend? A recent study surveyed over two thousand people in the United Kingdom and found that teenagers tended to show lower levels of connection to nature than both children and adults.

Salty about coastal walls

Artificial barriers are one of humans favorite thing to build. We build them to keep ‘other’ people in or out. We build them to keep animals in or out. And of course we build them to keep the natural environment out or our AC in. Usually walls are just temporary solutions to a much deeper problem which is definitely true in the case of sea level rise. Coastal communities need walls to protect against flooding. But what happens when to the impounded ecosystem when mother nature crashes through the wall anyway?

Ecological grief: In my feelings along the Gulf Coast

Aldo Leopold stated “One of the penalties of an ecological education is that one lives alone in a world of wounds.” He meant that those of us with deep connections to the natural environment, whether that be a farmer, fisher, or ecologist, are more aware of declining ecological health. We notice that there are less birds. We notice all the dead turtles along the road. We notice that it hasn’t rained in weeks and all the plants are crying. The unprecedented changes stemming from climate change have gained an increasing amount of people’s attention leading to the formation of the term ecological grief. The verdict is out. Climate change is making many of us depressed.

Tweet tweet: Using social media to help bird conservation

Conservation areas are vital to maintaining biodiversity, and as a result, it’s important to know which conversation areas humans are most likely to visit. Looking at publicly available social media data, researchers analyzed how many people posted on Twitter and Flickr in over 12,000 Important Bird and Biodiversity Areas across the globe. Understanding how many people visit what areas is important for funding, and eco-tourism, but also to see which areas may have higher threats with so many visitors.
