Classifying Freshwater Biota
This is the most productive of the functional groups found in freshwater lakes.
Producers
This is the open water area of a lake, below the thermocline, where the light does not penetrate.
Profundal zone
These are the primary reactants of photosynthesis
CO2, water and light
This copepod is carnivorous, has 2 egg sacs and a single eye spot.
Cyclopoid
This order of macroinvertebrates includes dragonflies and damselflies.
Odonata
This "approach" to classifying freshwater biota focuses on species as the functional unit. It is not as functional in limnology.
The taxonomic approach
This is the zone of a pond where you would find the fringing community.
Littoral Zone
These unicellular organisms are responsible for bioluminescence en la isla de encanta (Puerto Rico)?
Dinoflagellates
This is why zooplankton migrate away from the light and toward the thermocline every day.
Predator avoidance
This organism has a complex life history that requires the parasitic attachment to fish gills and fins as larvae.
Mussels
This functional group can be both/either autotrophic and heterotrophic. They truly are more than meets the eye.
Transformers
This group of organisms can be pathogenic and include malaria.
Protists
In temperate regions, this algal group is the first and last to dominate lake systems in eutrophic systems.
Diatoms
This is the smallest of the zooplankton groups.
Rotifers
These three orders are commonly used to assess the biotic integrity in a river reach.
Ephmeroptera, plecoptera, trichoptera
This is the functional group of large, motile swimming organisms in freshwater systems.
Nekton
This is the functional group that includes mosquito larvae.
Hyponeuston
This is the compound that replaces water, allowing sulfur to act as the final electron acceptor in the electron transport chain.
Hydrogen sulfide
This is the name of the dormant egg that cladocerans create to survive periods of disturbance.
Ephippia
This large "true bug" hemipteran is known for eating fish, snakes, and the occasional human toe.
Giant water bug
This German term refers to the entire "attached" community of organisms.
Aufwuchs
Organisms with this functional feeding "measure" are expected to increase in disturbed systems.
Omnivores and scavengers
This hepatotoxin is produced by these cyanobacterial species: Anabaena, Microcystis, and Aphanizomenon
Microcystin
This is the process by which cladocerans create morphological defenses from predators (helmets, neck teeth).
Cyclomorphosis
This is the family that includes sunfish/panfish that we use for sport and food.
Centrarchidae
