Leaving a Legacy: Plants leave “memories” in the soil that can affect future generations

It’s easy to drive by grasslands, forests, and deserts without thinking too deeply about how and why they have developed to be unique from one another. Still, most of us have an intuition of how community drivers work, such as recognizing that sandy soils and very hot climates encourage the growth of cacti instead of oaks. As an ecologist that has done a lot of work with restoration projects, I am particularly interested in thinking about all of the environmental “ingredients” that go into the recipe for each unique plant community. The day that I found out that plants can leave “memories” in soil which change communities long term, I immediately began thinking about how we could harness this knowledge for good and whether or not humans play a role in the development of these legacies.

Rich bird, poor bird: urban street trees support native birds across a socioeconomic gradient

If you’ve jumped on the bird-watching bandwagon to pass time during the pandemic or tuned in to #BlackBirdersWeek, you might have a new-found awareness of the birds outside your window or in your local park. What you may not have noticed is that urban birding experiences can differ greatly among neighborhoods.

Earth’s largest water reservoir could be 1,800 miles beneath the surface

When Jules Verne first published his story “Journey to the Center of the Earth”, it was fantasy that one could sail across a vast ocean deep below the surface of the earth, but many became fascinated by what could exist thousands of miles beneath our feet. These fantasies remain even today as we are unable to study the innermost layers of our planet directly, but new research techniques reveal the Earth’s core may be more like Verne’s version after all.

Accidental Breakthrough: An Unexpected Laboratory Hybrid of a Critically Endangered Fish Species

Sometimes scientific breakthroughs happen by sheer accident. That was certainly the case with scientists studying the Russian sturgeon. An unexpectedly successful cross-species breeding experiment resulted in the first documented surviving hybrids of Russian sturgeon and American paddlefish. This opens new doors and frontiers for fish genetics, aquaculture, and potential survival strategies for critically endangered sturgeon species.

A way forward: an ecological hypothesis to understand and predict disease spillover events

It is critical that we understand all of the pieces of spillover events so that they can be predicted and ideally prevented. Scientists at Auburn University recently considered the two main hypotheses for spillover, and asked how do pathogens with the potential to spillover from wildlife to humans arise in damaged or altered landscapes?

California Electrification – what buildings, the grid, and the environment need in an age of energy transition and climate change

A team of energy scientists from California tackle the big question of what will electricity demand look like in a changing climate? By analyzing the evolution of the electric grid to supply an increasing demand under the state’s climate action plan AND the increasing demand to make people comfortable in a variable and changing climate, these researchers have given imperative insight into the future of California electrification.

COVID-19 Watch: Wastewater Edition

The COVID-19 global pandemic has changed the world as we know it. As a society, this pathogenic virus presents challenges not only in preventing its spread and treating its victims, but also in monitoring its growth and/or decline throughout the population. In this study, researchers discuss utilizing wastewater as a possible pathway for tracking the presence/evolution of the SARS-CoV-2 pathogen in residential areas.
