“With fisheries for example, seagrasses provide nursery habitat for juvenile fish and foraging grounds for about 25% of the world’s biggest fisheries. "We identified associations between pressures and measured changes in seagrass extent and found that seagrasses are especially under threat from poor water quality and destructive fisheries like trawling."
"Seagrasses are flowering plants that live submerged in salty water and perform vital ecosystem services that help us and the food-webs that rely on them. For example, seagrasses capture and store more atmospheric carbon (per unit area) than many terrestrial plants, they act as nursery areas for important fishery species, and provide coastal protection against things like erosion and storm surges," Dr Ryan Pearson.

Deep learning has fast become recognised as a powerful data processing tool for ecologists faced with vast amounts of image-based data. The ability of deep learning to accurately detect target species in videos and images unlocks [...]
By Sebastian Lopez-Marcano Read Time: 344 words, about 3 minutes. Studying animal movement is crucial. Animal movement research is conducted to monitor ecosystem health, understand ecological dynamics and address management and conservation questions. In marine environments, there are different methods to measure fish movement. From nets, tags and statistical modelling, the use of different techniques [...]
Rivers, lakes, and wetlands support extraordinary diversity. Such bodies of water host more species per square kilometre than forests or oceans. Yet they are losing this biodiversity two to three times faster than forests and oceans. Populations of freshwater animals, including river dolphins, sturgeon, beavers, crocodiles, and giant turtles, have already plummeted by 88%.

New tools (i.e. deep learning / computer vision) are allowing data to be processed at vast rates which is making data more accessible and useful. However, converting raw data into meaningful insights for ecological research can be challenging. Data nodes. Photo: Akamai. Through the years, ecologists have become familiar [...]
Dr Ryan Pearson Read Time: 503 words about 3 minutes. The effects of COVID-19 on the world has been profound. We're now re-evaluating intergovernmental, trade and personal relationships, and rethinking our consumer needs. Environmental groups have been encouraging people to 'eat more fish' in response to this pandemic. Consumer surveys during the pandemic have also highlighted [...]
