The butterflies of Mona Island (Puerto Rico) and an approach to their origins and phenology
En: CARIBBEAN JOURNAL OF SCIENCE, 30 (1-2) June 1994: 95-103. bibl. il. tabla.
Revista: Caribbean journal of science, vol. 30, núm. 1-2; June 1994
Resumen: The butterfly fauna of Mona Island, situated between Puerto Rico and Hispaniola, is discussed in the context of its origin and phenology. Fifty-three species are known from the island, and the easterly bias in their origin, seen in butterflies that have diverged subspecifically on Hispaniola and Puerto Rico, is attributed to wind asymmetry.
Resumen: Question of vagrancy and colonization in present faunal structure are discussed. Records from seven visits suggest varied phenological patterns; factors that may determine distribution and abundance or rarity are considered, and the need for long-term work on population biology is emphasized.
Resumen: The level of endemism of Mona's biota, together with its geological history and geographical position, stress its unique importance in the Caribbean area for studies on island biogeography and evolutionary divergence.
