Document Summary
Co-evolution: reciprocal evolutionary interaction: a evolves in response to b, b in response to a. antagonistic co-evolution within a species (e. g. water striders having spines). Diffuse co-evolution: interaction between pollinators and hosts: not 1:1 (many bees and flowers). Specific co-evolution: fig and a fig wasp, this is more 1:1. Acoustic mimicry in a predator-prey interaction: behaviour of predator changes learns to stop taking moth (aposematism). Tiger moths jam bat sonar: found something that fits in the network of jamming. ***mountain pine beetle spread: due majorly to climate change (perlman) or old forest/ lack of fire (lindgren). Diapause: arrested development vs quiescence: boundaries aren"t clear. Quiescence vs diapause: diapause is very hard to turn back on instead of quiescence. Quiescence: put flies in an incubator at 12 degrees, they"ll slow down. Diapause: harder to go back to the original. Fitness of male-killing: symbionts maternally inherited males are an evolutionary dead end.
