Niche CD RP CEP

Coexistence through niche differentiation:

“Reduced competition” for coexistence through niche differentiation. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. A niche is the multidimensional set of abiotic conditions, resources, and biotic relationships under which a population can persist. The fundamental niche reflects physiological and resource limits, while the realized niche is modified by competitors, consumers, mutualists, and dispersal barriers. The remaining alternatives—“Competitive exclusion”, “Increased predation”, “Genetic dr

Semelparous herbs fall on which corner of growth-survival-fecundity triangle?

“Fecundity” for semelparous herbs fall on which corner of growth-survival-fecundity triangle. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Survivorship curves summarize age-specific mortality: Type I concentrates loss late in life, Type II approximates a constant hazard, and Type III concentrates loss early. They are empirical patterns, not rigid taxonomic rules. The remaining alternatives—“Growth”, “Survival”, “None”—refer to different states, processes, or scales and therefore do not express

Growth-survival-fecundity triangle classifies plants based on:

“Energy allocation patterns” for growth-survival-fecundity triangle classifies plants based on. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Selection favors the schedule that increases lifetime reproductive success under local mortality and resource conditions. Body size, development time, fecundity, parental investment, and generation length consequently tend to covary. The remaining alternatives—“Habitat structure”, “Ecological dominance”, “Nutrient concentration”—refer to different states,

Stress-tolerators are adapted to:

“High stress, low disturbance habitats” for stress-tolerators are adapted to. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Survivorship curves summarize age-specific mortality: Type I concentrates loss late in life, Type II approximates a constant hazard, and Type III concentrates loss early. They are empirical patterns, not rigid taxonomic rules. The remaining alternatives—“High resource, low stress habitats”, “Constant waterlogged environments”, “Periodic fire and drought”—refer to different
