Synapomorphies - Study guides, Class notes & Summaries

LMU Entrance Exam (Evolutionary Bio, Ecology, and Systematics) Fecundity maximum reproductive output Semelparity : all offspring produced in single event (favored in stable and predictable environments) Iteroparity offspring produced in many events throughout life (favored by unstable environments) Grazers attack a large number of prey but cause little damage on the individual level (mosquitos leeches, flies are grazers) Parasites symbiotic relationship where hosts fitness decreased while paras...
