National Aquarium’s Post

Bladderwort Utricularia is an aquatic insectivorous plant, devoid of roots and bearing trapping vesicles. Each bubble is equipped with a hole, closed by a valve that opens inward, as a result of which small aquatic animals can freely penetrate into the bubble, but cannot swim back out. When they die, they serve as food for the plant. In 2011, researchers from France and Germany recognized bladderwort as the fastest predatory plant in the world: prey is drawn into a trap in less than a millisecond. Pemphigus is distributed throughout the world, being absent only in Antarctica and a number of oceanic islands. The plant overwinters in the form of spherical buds. In favorable conditions at home, it can stop feeding on living organisms and begin to develop a root system, in what!

Why do seagulls fly over the sea? Because if they flew over the bay, they’d be bagels! Har har. Jokes aside, did you know that there's no such bird as a "seagull"? This name refers to a variety of sea birds, most of which are gulls and terns! In the Chesapeake you might come across a herring gull, royal tern, or ring-billed gull, which we saw this Wednesday while collecting tidal samples! Results from this week's bacteria samples are listed below. Check out baltimorewaterwatch.org to see data on all of the stations monitored throughout Baltimore's watersheds.

According to the state of Maryland, it's unsafe to come into contact with surface waters with enterococcus levels greater than 130 MPN/100 mL.

Macro invertebrates such as larvae of stonefly, dragonfly, caddisfly, etc. and worms, leeches, snail, etc. are most suitable to derive saprobic score that determines the quality of water. #BioMonitoring #BioIndicators #Environment

Proper aeration is crucial for maintaining a balanced and healthy lake ecosystem. Our aeration services at Clarity Lake Management promote oxygen circulation, reduce algae growth, and support aquatic life, ensuring a vibrant lake environment.

Top tip from the team at Reef: “We find this quite often; expansion Vessels should installed vertically. By their nature they form dead-legs. When horizontal, it creates a proper sump of stagnant water, in which bacteria can proliferate” 📧 postbox@reefwater.co.uk #reefwatersolutions #orac #waterhygeine #watercompliance #southeast #southwest #nationwide #getintouch

Macroinvertebrates are recognized as the most suitable organisms for bio-monitoring as they have low mobility, are in contact with both sediments and the water column, thus being exposed to pollutants in both compartments, and display a wide range of tolerance to contaminants (including from highly sensitive species to species that are very tolerant to polluted conditions).Thus, environmental disturbances can modify the structure of Macroinvertebrates assemblages in response to several stressors. Currently learning to identify these benthic Macroinvertebrates to determine the level of pollution in water bodies. #research #bioindicators 

Diatomaceous earth (silicon dioxide) is composed of fossilized, pulverized aquatic organisms and is safe for people and pets. It leaches oil from the skeletons of insects, drying them out. Sprinkle this powder anywhere you see ants entering or moving in your house. Reapply often. It’s safe for children and pets.

Cleaning Water Naturally the Ancient Maya Way The Maya created constructed wetlands, which, as defined by the EPA “use natural processes involving wetland vegetation, soils, and their associated microbial assemblages to improve water quality.” No chemicals were needed like water treatment plants use today. In a constructed wetland, aquatic biota work together to maintain water quality. Aquatic plants like cattails, water hyacinths, reeds and others take up nutrients, while biofilms created by decomposing plants break down nutrients. Florin Batea https://lnkd.in/dWmAHDJi
