Invasive species attributes: rapid development to reproduction, high reproductive output, well-developed dispersal mechs. Invasion in the context of agriculture: mimicry, examples: weeding. Pulling out weeds that look different from crops. over time selection can alter phenotype: weeds adapt to resemble rice. Invasive species in ontario: zebra mussels, high fecundity, abundant, extensive damage to water intake pipes. effects households, electrical utilities and sport fishing: higher costs than benefits. benefit: filter feeder cleaner water: lead to high avian mortality www. notesolution. com.
