Document Summary
Interspecific interactions- as populations continues to grow, the effects of density- dependent interactions with other species increase. Parasitism, disease- detrimental organisms infesting or infecting a host species e. g. deer- cwd; bird- avian cholera; +/- interaction (benefit for the parasite) Interspecific interactions- interactions with other species may not be detrimental. Mutualism- both species are benefiting e. g. lichen-tree; fish-shrimp; ants- aphids; Honey badger- honey guide (bird); ambrosia beetles-fungus; animal-flower (pollinate); +/+ interaction. Limiting factors- the presence, absence, or magnitude of biotic and abiotic environmental factors can limit population growth. Commensalism- one species benefit the other doesn"t have effects e. g. limit nutrians to plants grow; ash-throated flycatcher and franklin"s gull both. Thresholds increase the chances of rapid environmental and ecological change percent forest cover on newt occurrence in ponds. What we deal with as conservationists is the applied ecology of populations of species surrounded by environments licing together inassenblages within communities within ecosystems.
