Christine, an undergraduate Biology student, set out to collect invertebrates in ephemeral ponds of varying longevities at Breakneck Creek, Kent. Here are some photos of her sites. The yellow/greenish dusting over the water is pollen from surrounding trees: apparently pollen was heavy in North Eastern Ohio, just as it was record breaking in Atlanta this Spring.
Some standards and polar extractives used to determine total phenolic content in litter samples.
Because 60 small (50 mL) flasks look cool.
Add concentrated sulfuric acid and produce an oxidized slurry of organic matter.
Dilute the acid with distilled water, cover and autoclave the slurry
Pre-weigh glass fiber filters
Vacuum-filter slurry onto the pre-weighed filters
Dry and reweigh filters.
