High levels of mercury have been detected in Florida's Indian River dolphins and the areas local human residents because they both consume the same seafood.
Deciduous trees along rivers and streams provide protection from damaging solar radiation and valuable foliage every autumn. Fallen leaves act as a vital food source for insects, and keeping insect populations healthy could ultimately help river ecosystems combat climate change, researchers reveal in a new study.
A deadly fish disease known as VHSv has plagued hundreds of freshwater fish in Lake Winnebago, in Wisconsin. While some older individuals have developed a resistance toward the disease, they could spread the disease to younger fish and cause another mass die-off in the future.
Caucasian Parsley Frogs (Pelodytes punctatus) feed on insects breeding in the feces of bats in remote limestone caves near Russia, researchers discovered. Their study sheds light on the importance of species conservation.
Marine food chains may crumble in the wake of warming oceans and acidification, according to a global marine analysis. Even the slightest environmental change could have a much broader impact on a wider range of species than we realize.
A seal riding atop a humpback whale – like this photo from Eden, New South Wales, shows illustrates an extremely rare occurence but other animals routinely help each other out.
Environmental changes large or small can have a significant impact, according to a recent study. This may help ecologists better understand a community's response to climate change.
The 2015 Coastal Shark Survey, one of surveys that have taken place every two to three years since 1986, recorded 2,835 sharks that were captured and tagged for monitoring.
In addition to the raging wildfires, the Pacific Northwest lowlands are experiencing devastation in mountain pond habitats as a result of climate change. According to recent forecast models, this just may be new norm that amphibians have to get used to.
Much like people living in packed cities, it may be now that animals of prey in Africa have a smaller number of offspring when living in crowded conditions. Turns out, this is affecting lions and other predators.
Jellyfish provide easy access to hunting grounds for some sea birds, since they attract small fish to hang around their tentacles in exchange for plankton.
The highly invasive New Guinea flatworm, which spreads quickly and upsets the food chain, has been sighted in Florida.
What would you say is most important to Africa's ecosystems? Is it isolation, stability, or maybe biodiversity? According to a new study of Africa's essential rivers, it's none of those, as hippo dung is actually the "life force" that keeps the region vibrant and alive.
It's no secret that climate change has been affecting our oceans, with things like warming surface temperatures and rising acidity affecting various species across the world. Now a new report has revealed that the West Coast of North America may be feeling changes so intense that it is altering the overall productivity of local waters, leading to a reduction in marine species spanning from seabirds to salmon.
Plants, ants, and bears, oh my! It seems that these three organisms are in an interesting war of influence, so to speak, in Colorado meadows. A war that researchers are calling a prime example of the largely unconsidered roles that top predators play in ecosystems.
