Aquatic ecosystem An aquatic ecosystem is an ecosystem in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. — Wikipedia

Science

Marine biology is the scientific study of marine life, organisms in the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.

A large proportion of all life on Earth lives in the ocean. The exact size of this large proportion is unknown, since many ocean species are still to be discovered. The ocean is a complex three-dimensional world covering approximately 71% of the Earth’s surface. The habitats studied in marine biology include everything from the tiny layers of surface water in which organisms and abiotic items may be trapped in surface tension between the ocean and atmosphere, to the depths of the oceanic trenches, sometimes 10,000 meters or more beneath the surface of the ocean. Specific habitats include coral reefs, kelp forests, seagrass meadows, the surrounds of seamounts and thermal vents, tidepools, muddy, sandy and rocky bottoms, and the open ocean (pelagic) zone, where solid objects are rare and the surface of the water is the only visible boundary. The organisms studied range from microscopic phytoplankton and zooplankton to huge cetaceans (whales) 25–32 meters (82–105 feet) in length. Marine ecology is the study of how marine organisms interact with each other and the environment. — Wikipedia

Aquatic fungi: Forgotten conservation targets
on May 19, 2022 at 2:20 pm
They are always there, dwelling in the water, where they play a key role in food webs, in cycling of nutrients, matter and energy, and water purification. However, as happens with organisms that tend to be inconspicuous and often invisible to the naked eye, society mostly neglects them, and forgets their huge importance in providing support and stability of aquatic ecosystems. What is even more problematic, we also forget that they are exposed to a wide range of threats from human activities. […]

In a major step forward for monitoring the biodiversity of marine systems, a new study published today in Environmental DNA details how MBARI researchers are using autonomous underwater robots to sample environmental DNA (eDNA). eDNA allows scientists to detect the presence of aquatic species from the tiny bits of genetic material they leave behind. This DNA soup offers clues about biodiversity changes in sensitive areas, the presence of rare or endangered species, and the spread of invasive […]

It's no secret that Earth's biodiversity is at risk. According to the International Union for the Conservation of Nature, 26% of all mammals, 14% of birds and 41% of amphibians are currently threatened worldwide, mainly due to human impacts such as climate change and development.

It's not enough to understand what the effects of climate change are. Society needs ways to get ahead of these changes, to predict them before they actually happen. And when it comes to conservation, the approach scientists use to study species in the wild could be critical to these predictions, according to a recent research review led by biologist Stephanie Green and published in Proceedings of the Royal Society B: Biological Sciences.

Where do 'Hawaiian box jellies' come from?

Scientists discover the enzymes responsible for the production of one of the most toxic and fast-acting neurotoxins associated with freshwater harmful algal blooms in lakes and ponds. The discovery revealed that guanitoxin-producing cyanobacteria are more prevalent than originally known in the United States, opening the possibility for new molecular diagnostic testing to better inform and protect the public from this natural freshwater toxin.
