Fitness (often denoted or ω in population genetics models) is the quantitative representation of individual reproductive success. It is also equal to the average contribution to the gene pool of the next generation, made by the same individuals of the specified genotype or phenotype. Fitness can be defined either with respect to a genotype or to a phenotype in a given environment or tim… Web18 minutes ago · Butterflies and moths (Lepidoptera) are one of the most ecologically diverse and speciose insect orders, with more than 157,000 described species. However, the abundance and diversity of Lepidoptera are declining worldwide at an alarming rate. As few Lepidoptera are explicitly recognised as at risk globally, the need for conservation is …
