Easter Island is a small 63-square-mile patch of land — more than a thousand miles from the next inhabited spot in the Pacific Ocean. In A.D. 1200 (or thereabouts), a small group of Polynesians — it might have been a single family — made their way there, settled in and began to farm. When they arrived, the place was covered with trees — as many as 16 million of them, some towering 100 feet high.
These settlers were farmers, practicing slash-and-burn agriculture, so they burned down woods, opened spaces, and began to multiply. Pretty soon the island had too many people, too few trees, and then, in only a few generations, no trees at all.
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.
