Mentally “exhausted” honey bees—petroleum exhaust makes bees learn slower and forget faster

Scent pollution from exhaust fumes could disrupt the relationship between honey bees and the flowers they feed from and pollinate. The smell of flowers invites pollinators to come and feast on their nectar. But exhaust masks those smells, making it harder for bees to learn and remember the floral scents that cue them in to flowers.

Poison Ivy’s Pervasiveness

Are you part of the 80% of the population that is allergic to poison ivy? What do we really know about poison ivy beyond its potential to cause an itchy rash on our skin? Poison ivy can actually adapt to its environment and exploit a variety of habitats, which helps explain its ubiquitous distribution. A future climate with greater carbon dioxide concentrations is expected to expand its distribution and increase its toxicity – bad news.

The Future of Seafood: Integrated Multitrophic Aquaculture

Aquaculture has long been revered as a benefit to the seafood industry by increasing food availability for developing nations and taking pressure off of overexploited wild fish stocks. However, aquaculture has also been cited for its negative environmental impacts. Integrated Multitrophic Aquaculture (IMTA) is a solution that combines species of different trophic levels to be grown together in the same aquaculture setting, reducing environmental impacts and increasing overall production.

Islands and Alleles: How genetics can help protect endangered species

When talking about diversity in the natural world, we often think of the bright colors and bold patterns of fish gliding among a reef, or the variety of flying, creeping, and crawling critters found in the layers of a rainforest canopy. However, diversity even within a single species is an important indicator of a population’s health and stability. This type of diversity can be invisible to us when contained in the form of genes that control which traits organisms possess. In this study, scientists helped us to see the invisible diversity of an endangered skink and learn how to more effectively conserve this diversity.

Mother of dragons in the city

City habitats are often much warmer due to lower forest cover and an increased density of manmade surfaces which retain heat. Increased temperatures can greatly affect animals that develop as male or female depending on the incubation temperature of the eggs. Read on to find out how mothers of eastern water dragons deal with living in the warm cities of Australia.

Hidden fish populations protect us from ourselves!

We raise cows, chickens, and pigs on farms, but we still commonly hunt wild populations for one type of animal protein- seafood. Many fish populations are overexploited, but scientists found that despite this, Atlantic flounder populations were in better shape than expected. Why? How can we ensure that this stability continues?

Microplastics take flight—how mosquitoes move microscopic pollutants from water to land

Discarded plastics aren’t only disrupting the ocean, they accumulate in freshwaters too. And the impacts may not end there. Aquatic insects eat microplastics and, when they become adults, carry the polluting particles from water onto land and potentially into the stomachs of their predators.

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.
