To help save the mountain lion population from local extinction, an $87m (63m) wildlife bridge is planned over the 101 highway north of LA, which would be the largest in the world. This means that in order to get food and nutrition, these protists must eat/ingest food from their environment.

The algae that causes the region's blooms, Alexandrium catenella, mostly lingers in two offshore locales. Cysts are highly resistant cells that typically form in large numbers as blooms terminate. Everyone can see that a cow eats grass and hay, a lion attacks and eats a gazelle, and an oak tree's leaves convert the sun's light into glucose for energy, etc. It contains some of the dinoflagellate species most harmful to humans, because it produces toxic harmful algal blooms (HAB) that cause paralytic shellfish poisoning (PSP) in humans. 2021 Feb;102:101989. doi: 10.1016/j.hal.2021.101989.

However, Colin and Dam (Colin and Dam, 2003) found that the depression of feeding rate of copepods exposed to high concentration of Alexandrium fundyense could be alleviated if copepods were exposed to low concentrations of A. fundyense before the test, which indicates that the negative response of ephyrae exposed to high concentrations of A. catenella might be alleviated if ephyrae were acclimated to low concentration in the coastal waters. Blooms of the highly toxic dinoflagellate Alexandrium catenella (previously referred to as tamarense group 1) were first detected off eastern Tasmania in 2012 and have since been responsible for incidences of human paralytic shellfish poisoning and extended closures (up to 25 weeks) of mussel, oyster, scallop, abalone and rock lobster industries (up to 150 mg/kg PST in mussels).
