When it comes to finding protection and a safe feeding ground, fish rely on towering blades of seaweed, like kelp, to create a three-dimensional hiding space. Kelp forests have been shown to be one of the most productive systems in the ocean with high biodiversity and ecological function. However, in recent decades, many kelp habitats have been taken over and replaced by lower turf-dominated seaweed species. Researchers at the University of New Hampshire have found that this change in the seascape may impact the behavior of fish and could be leaving them less options for refuge and more vulnerable to predators.

The 2014 Ebola outbreak in West Africa killed more than 11,000 people and was the deadliest outbreak since the discovery of the virus in 1976.

A new study has uncovered when and why the native vegetation that today dominates much of Australia first expanded across the continent. The research should help researchers better predict the likely impact of climate change and rising carbon dioxide levels on such plants here and elsewhere. The dominant vegetation, so-called C4 plants, includes a wide variety of tropical, subtropical and arid-land grasses. , C4 plants also include important worldwide crops such as sugarcane, corn, sorghum and millet. The research has just been published online in the journal Geophysical Research Letters.

Industrial fisheries that rely on bottom trawling wasted 437 million tonnes of fish and missed out on $560 billion in revenue over the past 65 years, new UBC research has found.

More Canadian cities will experience damage from the emerald ash borer than previously thought. As a result of climate change and fewer days of extreme cold, the beetle may eat its way further north than originally estimated.

A new, unusually large virus that infects common marine algae has been characterized by researchers at the Daniel K. Inouye Center for Microbial Oceanography: Research and Education (C-MORE) at the University of Hawaiʻi at Mānoa‘s School of Ocean and Earth Science and Technology. Found in the coastal waters off Oʻahu, it contains the biggest genome ever sequenced for a virus infecting a photosynthetic organism.

New University of Alberta research on managing aquatic invasive species in Canada combines the power of machine learning with expertise in biology and statistics to build a simple, easy-to-use tool for environmental managers.

Many of the European mammals whose habitat is being destroyed by climate change are not able to find new places to live elsewhere.

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.

Goodbye, winter. Hello spring. Hello sunshine, blossoms, birdsong, … pollen, itchy eyes, runny nose …
