it could be unappealing for play or more costly to clean for drinking. But the color changes wouldn’t necessarily mean that the lakes are any less healthy. “Humans don’t value lots of algae in a lake, but if you’re a certain type of fish species, you might be like ‘this is gr...
To the detriment of those benefits, however, coral reefs have been deteriorating since the 1970s under a cascade of human impacts. Overfishing disrupts their complex communities of large predators, smaller prey species and “grazers” such as parrotfish and urchins that clean large algae off corals...
"The new species of cichlids adapted to use all the available food resources in thelake. Some feed on insect larvae, others zooplankton or algae. Some newly discovered fish are predators with large teeth, which we named 'large-tooth serranchromines'." Many people assume fish are all the sa...
Forty juvenile rainbow trout were obtained from the Cold Lake Fish Hatchery, Alberta, 2 weeks before the start of the experiment. At our field site, trout and crayfish were housed separately in 100-gal black troughs filled with well water, while the lesser beetle larvae and water tigers were...
Microbial structuring of an estuary sediment. Dissolved organic matter is almost exclusively taken up by bacteria and respired as CO2or re-introduced into the classical food chain (phytoplankton, zooplankton and fish). This, in turn, alters the carbon cycle that influences the microbiome as well ...

Like plants, algae such as the marine diatom Pseudo-nitzschia multiseries can release L-tryptophan, which can be converted by bacteria into IAA to stimulate algal growth [96]. Chlamydomonas can secrete tryptophan [97], providing symbiotic microbes with the appropriate substrate for IAA production. ...
