Seaweed as far as the eye can see

In the center of the Atlantic Ocean lies the Sargasso Sea. The brown seaweed, Sargassum, gives the Sea its name; However, in the past decade this belt of Sargassum has been exploding. During certain seasons, the Sargassum belt has expanded from West Africa to the Americas. Beached seaweed has led to numerous problems and concerns for much of the Caribbean, Central America, and South America. Research led by Dr. Mengqiu Wang from the University of South Florida used previous data to determine what makes these seaweeds take over the ocean in order to better predict when these blooms may occur.

Pharmaceutical and Personal Care Products Alter Lake Food Webs

The pharmaceutical and personal care products we use daily enter aquatic environments. Phytoplankton, or microscopic algae, are important pieces of the aquatic food chain. Phytoplankton exposed to pharmaceutical and personal care products in two Norwegian lakes responded quickly and dramatically – altering their community structure. The effects of these compounds on phytoplankton suggest these compounds have the potential to alter the food webs of entire aquatic ecosystems.

Chocolate beans and Brazilian birds

Global popularity of chocolate has led to intensive cacao bean cultivation, creating far-reaching environmental and social consequences. Agroforestry is a sustainable cultivation method that can reduce environmental impact. It is known to sustain native plants and animals more effectively than monocultures; but how do agroforestry areas compare to pristine forests?

Dead trees and utility poles partially offset the impacts of deforestation on birds

Mature trees serve as important habitats for a variety of species including insects and birds. Birds use trees for many purposes including nesting, perching, and foraging. Conservationists are exploring strategies to maintain bird populations in areas where mature trees are being lost due to agricultural expansion, wood production, and increased urbanization. In a recent study, scientists in Australia measured how utility poles and erected dead trees impacted the number and abundance of bird species in urbanized regions. The results suggest that artificial structures can offset some, but not all, of the bird loss due to deforestation.
