Document Summary
Sexual reproduction via spores, some strategies: diversity + dispersion, recent niches fungi have made for themselves, medical niche: immunocompromised humans, cryptococcus has its own recent niche too: idiot hikers in forest. Asexual reproduction/anamorph: methods, binary fission, budding (yeast, asymmetrical, spore production: (cid:2) arthrospores (cid:2) conidia (cid:2) sporangiospores (cid:2) chlamydospores (ascomycota, but used as a last resort, like bacterial spores) Both asex and sex spores need to be dispersed. Insect vectors in stinkhorn, cordyceps: motile gametes in chytrids, passive + cooperatively generated wind, fungal artillery: active, solar-guided hydrostatic cannon, pilobolus: sheppard"s fave fungus. Reservoir in cow colon, grows and spreads via cow fungus: predaceous fungi: Dactylaria sp. , arthrobotrys sp: live in soil, often symbiose w/ plants (cid:2) eat nematodes (plant enemies), catch via traps: (cid:2) sticky knobs or nets or rings (nooses) made of hyphae. In eu most bats are immune: destructans (ascomycota) conidia. Bats are an insect controller, and pollinators (esp for agave cactus, avocadoes)
