BIOEE 1610- Prelim 2 Study Guide Exam Questions and answers () 6 types of species interactions - exploitation (+/-), competition (-/-), mutualism (+/+), neutralism (0/0), commensalism (+/0), amensalism (-/0) compeition - species interaction where two organisms compete for any limited resource (can be context dependent- ex. temperature, humidity, etc. can affect species behavior/performance) intraspecific competition - competition among individuals of the same species (as population size increases, infraspecific competition increases) interspecific competition - competition among individuals of different species exploitative competition (resource competition) - indirect competition reducing availability of shared resources interference competition - direct competition for scarce resources by one denying access to the resource by another competitive exclusion - When two species are very similar, they may not be able to coexist (strong competition can lead to poor competitor going randomly locally extinct) Resource Utilization Curve - shows utilization of types of resources amongst different species Niche Concept - the range of environmental conditions and resources within which individuals of a species survive, grow, and reproduce Fundamental Niche - full hyper volume or range of environmental factors permitting a species to survive and reproduce (abiotic) Realized Niche - the conditions under which an organism actually exists, after limitations (competition, disease, predators, etc. / Biotic / smaller than fundamental niche) Niche dimensions - temperature, humidity, prey size n-dimensional hypervolume - n = number of environmental factors and resources important to the survival and reproduction of the species (n can define multiple biotic and abiotic resource axes)
