Algae might seem easy to ignore, but they are the ultimate source of all organic matter that marine animals depend upon. Humans are increasingly dependent on algae, too, to suck up climate-warming carbon dioxide from the atmosphere and sink it to the bottom of the ocean. Now, by using a combination of satellite imagery and laboratory experiments, researchers have evidence showing that viruses infecting those algae are driving the life-and-death dynamics of the algae’s blooms, even when all else stays essentially the same, and this has important implications for our climate.

Compromise solutions must be found when it comes to roads built through sensitive tropical and subtropical areas, say experts writing in the Cell Press journal Current Biology on August 18. While developing nations need to deploy adequate transportation infrastructure to develop mineral and energy resources, the researchers write, governments too often put development ahead of wildlife without thinking about the long-term consequences.

The selective logging of trees in otherwise intact tropical forests can take a serious toll on the number of animal species living there. Mammals and amphibians are particularly sensitive to the effects of high-intensity logging, according to researchers in the Cell Press journal Current Biology on July 31 who conducted a meta-analysis of almost 50 previously published studies from around the world.

Many studies have shown the potential for global climate change to cut food supplies. But these studies have, for the most part, ignored the interactions between increasing temperature and air pollution — specifically ozone pollution, which is known to damage crops.

New research from North Carolina State University shows that urban “heat islands” are slowly killing red maples in the southeastern United States. One factor is that researchers have found warmer temperatures increase the number of young produced by the gloomy scale insect – a significant tree pest – by 300 percent, which in turn leads to 200 times more adult gloomy scales on urban trees.

The future health of the world’s coral reefs and the animals that depend on them relies in part on the ability of one tiny symbiotic sea creature to get fat—and to be flexible about the type of algae it cooperates with. In the first study of its kind, scientists at The Ohio State University discovered that corals—tiny reef-forming animals that live symbiotically with algae—are better able to recover from yearly bouts of heat stress, called “bleaching,” when they keep large energy reserves—mostly as fat—socked away in their cells.
