Niche theory niche n-dimensional hyper-volume Which defines the set of environmental conditions within which a species can (a exist/survive, (b)complete its life cycle potential niche realised niche physiological niche ecological niche
Niche theory niche = n-dimensional hyper-volume which defines the set of environmental conditions within which a species can (a) exist/survive, (b) complete its lifecycle potential niche realised niche physiological niche ecological niche
high Tolerance range Vigor of Plant can grow in plant growth these perera Mites and Plant will not grow competitive in these conditions, ablity outside tolerance CDnn as range low sCeGuerStn Environmental variable ( e.g. sunlight, temperature, water)
Modelling plant/animal distributions full niche specification difficult/impossible? potential environmental domain response to primary environmental regimes meso-scale climate response=> potential bioclimatic domain potential climatic distribution
Modelling plant/animal distributions full niche specification difficult/impossible? potential environmental domain = response to primary environmental regimes meso-scale climate response => potential bioclimatic domain potential climatic distribution
