AllFishNoBrakes Posted March 29, 2023 Share Posted March 29, 2023 @Levi_Aquatics Yup, that’s what the article said. Apparently, the Great Salt Lake is responsible for 40% of the worlds brine shrimp supply and brine shrimp are 600,000 years old. Pretty cool stats 1 Link to comment Share on other sites More sharing options...
Streetwise Posted April 12, 2023 Share Posted April 12, 2023 Lake Tahoe’s best clarity in 40 years is the work of this ‘natural cleanup crew’ https://www.theguardian.com/us-news/2023/apr/11/lake-tahoe-clarity-visbility-zooplankton Partial quote: The dramatic change can be attributed to an uptick in the concentration of zooplankton, tiny critters that are specialized to consume particles that inhibit the lake’s visibility and an unexpected depletion in the numbers of Mysis shrimp that normally would eat those zooplankton. According to Schladow, the zooplankton, especially the Daphnia and Bosmina species, “largely disappeared from the lake after they were grazed down following the introduction of the Mysis shrimp in the 1960s”. 3 Link to comment Share on other sites More sharing options...
nabokovfan87 Posted June 26, 2023 Share Posted June 26, 2023 (edited) https://phys.org/news/2023-06-sharks-humans-california-coast-previously.html I will start with the above, pretty awesome to see new technology applied in this fashion, especially when we have access to really useful photo analysis tools. Quote In looking at their video, the research team found that humans and sharks were near one another more often than previously thought. They found, for example, that 97% of the time when a person was in the water at the two most popular beaches, there was a shark nearby. In most instances, they were white sharks, which are not known to be aggressive toward humans. The researchers also found that the sharks, most particularly juvenile sharks, tended to swim much closer to shore than previously thought, oftentimes venturing to within 50 to 100 meters from the beach. They also found that when sharks and humans were in proximity, the human did not appear to know that the shark was there. The researchers also found that there was only one account of a shark biting anyone in the areas where they were filming over the period of their study—and just 20 since 2000. They note that numbers did not appear to be rising despite more people venturing into the ocean along California's coast and rising numbers of sharks living in the area due to warming ocean temperatures. I will also put this here because it's kind of cool. Research trying to save whale sharks using tags, trying to find out where they go for juveniles (basically breeding ground) and finding them in a new location. I know this is immensely old. I would love to see a newer study or newer information based on the species. They are highly endangered and it's not looking good because of the size of the fish and the size of the fin....https://phys.org/news/2014-08-newly-juvenile-whale-shark-aggregation.html Here's two really cool brief articles showing whale sharks doing cool things 🙂 https://phys.org/news/2023-06-whale-shark-bottom-feeding.html https://phys.org/news/2023-05-whale-sharks-parasites.html Edited June 26, 2023 by nabokovfan87 added video 1 Link to comment Share on other sites More sharing options...
