Document Summary
There is a sexual dimorphism among the polyandrous spotted sandpiper - the female is larger and defends the territory. There can be up to three males incubating. They can lie up to five clutches, four eggs, 20 eggs, 40 days, 4 times her weight: there is a high probability that the eggs would be lost, they lay many eggs because of the inclement weather. At higher altitudes, there is a lower oxygen concentration in the air: there were also more blood cells, and thus more hemoglobin, the molecule that stimulates the increase in the number of red blood cells is erythropoietin. Acclimatization is a phenotypic change that occurs in an individual in response to a short-term change in environmental conditions. The ability to di this is an adaptation. To review acclimatization: it would be an individual in response to environmental change. To review adaptation: it is something that it a trait in the population, and passed over time.
