Algae field collection

For fungi and some algae fresh field-collected specimens often are a source of insects and mites. Not only can these arthropods destroy specimens, but they can also destroy a culture collection by contamination as they move from one tightly sealed culture to the next. Mites also are suspected vectors in horizontal gene transfer between Drosophila spp.,25 and perhaps this form of contamination may be detected in fungi and algae one day. 

Aggregates can be produced in the laboratory by using material from alga] cultures (23) or material collected in the field in locations where marine snow... 

The UCB group also performed triazine EIAs on samples from agricultural evaporation ponds in the San Joaquin Valley. These ponds collect drainage from fields where triazines may be used, and thus have the potential for accumulating these, and other pesticides. Metal ions, salts, and suspended solids accumulate in amounts up to 20 times those found in sea water, and various species of bacteria, algae and even brine shrimp may propagate in water from these...
