Natural selection affects the scope of the niche of a given species. Moreover, trade-offs are associated with differences in traits that also may affect the niche of a species.
<h3>Natural selection and trade-offs </h3>
Natural selection refers to the differential survival or reproduction of individuals in particular environmental conditions.
The different niches occupied by species are mainly a consequence of differential trade-offs among species, i.e., by differential phenotypic features that generate negative correlations among species.
Grime’s Triangle is based on the associations (trade-off) between adaptation to productivity and/or competition, stressful environments (habitats) and disturbance.
