Conservation Conundrum: Is Focusing on a Single Species a Good Strategy?

Conservationists often criticize state fish and game departments for focusing single-mindedly on one species to the detriment of everything else — for instance, improving habitat for elk, which then browse down habitat for songbirds. But what if conservationists — who don’t have that traditional hook-and-bullet mindset — nonetheless inadvertently do much the same thing?

Marine Animals Have Been Following Their Preferred Climate for Millions of Years

Current global warming has far-reaching ecological consequences, also for the Earth’s oceans. Many marine organisms are reacting by migrating towards the poles. Researchers at Geozentrum Nordbayern at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have now discovered that marine animals have been migrating for millions of years when the temperature on Earth increases or decreases (https://onlinelibrary.wiley.com/doi/full/10.1111/geb.12732).

Small Birds Almost Overheat While Feeding Their Young

For decades, researchers have thought that access to food determined the brood size of birds. Now, biologists at Lund University in Sweden have discovered a completely new explanation: the body temperature of small birds can increase by more than 4°C to exceed 45°C when they are feeding their young. Larger broods would require more work, resulting in even higher body temperatures - something the birds would probably not survive.

Global Temperature Rise of 2°C Doubles the Population Exposed to Multiple Climate Risks Compared to a 1.5°C Rise

New research identifying climate vulnerability hotspots has found that the number of people affected by multiple climate change risks could double if the global temperature rises by 2°C, compared to a rise of 1.5°C.

Hippo Waste Causes Fish Kills in Africa’s Mara River

Ecologists have long known that agricultural and sewage pollution can cause low oxygen conditions and fish kills in rivers. A study published today in Nature Communications reports that hippo waste can have a similar effect in Africa’s Mara River, which passes through the world renowned Maasai Mara National Reserve of Kenya, home to more than 4,000 hippos.
