Aquatic Insect Final
| Question | Answer |
|---|---|
| Functional Feeding Groups | Type of food, the way it is acquired and the different subdivisions of consuming |
| Scrapers | insects that consume periphyton and epiphyton |
| Peircers | insects that consume material inside cytoplasm of cells on filamentous algae and macrophytes |
| Collectors Gatherers | insects that feed on FPOM on sediment surfaces |
| Scraper Mouthparts | blade-like inner margin on mouth, brushes, rakes, combs, excavators |
| Piercer Mouthparts | asymmetric cutting blade on mandible, forelegs to hold onto plant matter, large abdomens and larger stomach |
| Collector Mouthparts | brushes and feathery combs (simular to scraper) |
| Shredders | insects that shred organic matter for food (prefer bacteria on the leaves) |
| Shredder Mouthparts | microbial symbiotes (to maximize poor nutrition source), large gut, picky eaters, alkaline gut |
| Xylophages | insects that feed on wood. Wood biofilm is more important |
| Xylophage Mouthparts | heavily sclerotized mandibles and gut microbial symbiotes |
| Periphyton | microalgae growing on submerged surfaces in the water |
| Epiphyton | biofilm growing on stems and leaves of aquatic plants |
| Biofilm | complex community of diatoms, other algae, and bacteria and fungi |
| Collector Filterers | Insects that collect suspended organic matter |
| Encounter | being in the same place at the same time |
| Active Predation | predatory encounters that result in higher quality food, and are dependent on both the prey and predators activity |
| Ambush Predation | predatory encounter that is only linked to prey mobility |
| Engulfing | swallow prey whole or in solid lumps |
| Engulfing Mouthparts | hooked and long maxillae for holding, mouthparts are cupped and larger |
| Piercers (predator) | suck body fluids or products of external digestion. Able to eat organisms much larger than themselves |
| Piercer (predator) Mouthparts | raptorial or prehensile appendages, long siphon |
| Spatial Refugia | avoidance strategy that includes hiding in substrate not accessible to predators |
| Temporal Refugia | avoidance strategy that includes existing at a different time than predators |
| Non-consumptive Effects | predator-induced changes in prey traits |
| Consumptive Effects | effect of predator consumption on prey density |
| Disturbance | any discrete event in time that removes individuals from a space or opens up space and creates opportnity |
| Hydroperiod | schedule of filing/drying |
| Desiccation-resistant Stage | eggs that are laid in plant stems or in gelatinous coatings to prevent drying |
| Subsidy-stress Hypothesis | Increase in resources leads to an abundance of organisms, but as the algae develops it becomes inedible and begins to cause damage |
| Oligotrophic | low nutrients, light can reach bottom of the water column |
| Bioonitoring | use of living organisms or their response to determine the quality of an aquatic environment |
| Hilsenhof Biota Index | assigns tolerance scores to aquatic insects to determine how an environment is impacted |
| Allochthonous Resources | energy derived from primary production occurring outside the ecosystem |
| Cross ecosystem subsidy | movement of energy and nutrients across ecosystem boundaries that provide benefits to recipient consumers |
