          Abstract

          Este estudio describe los patrones de diversidad y distribución de la subfamilia Satyrinae en la cuenca del río Coello (4º 17’ 08’’ N y 74º 35´ 36" W; 1 899.31 km²), en un gradiente altitudinal de 433 a 3 600 m.s.n.m, con el fin de determinar la diversidad y composición regional y local de este grupo de mariposas y su posible uso como indicador biológico de zonas montanas y de Páramo. Se establecieron 11 estaciones de muestreo las cuales incluyen distintas zonas de vida. Las muestras se recolecciónron durante un periodo de 11 días en marzo, mayo, julio y octubre de 2003, en tres tipos de hábitat (bosque, borde de bosque y pradera). La recolección fue al azar en transectos de longitud no definida, entre las 09:00 y las 15:00 hr, empleando para ello redes lepidopterológicas de 0.5 m de diámetro y 1.20 m de longitud. Para el análisis de datos se calculó el índice de riqueza de Margalef (D) y se registró el porcentaje de abundancia relativa para las especies. La diversidad total por localidad y por hábitat se analizó a través del índice de Shannon (H’). De las matrices de presencia-ausencia se obtuvo índices de similitud entre estaciones, según coeficiente de Jaccard. Se recolectó un total de 239 individuos de 13 géneros y 34 especies. Las especies más abundantes fueron especialmente del género Pedaliodes, representando el 41.4%. La riqueza y diversidad, presentaron un comportamiento similar, mostrando altos valores en zonas montanas y de Páramo (> 2000 m.s.n.m). En cuanto a la diversidad por hábitat, se observó la mayor diversidad en el borde de bosque. El análisis de similitud evidenció dos grupos claramente definidos. El primer grupo contempla especies propias de zonas cálidas (Euptychia hesione y Hermeuptychia hermes) y templadas (Pseudohaetera hypaesia y Taygetis celia), mientras el segundo presenta especies exclusivas de zonas montanas y de Páramo (Lymanopoda obsoleta, Pedaliodes polusca y Eretris calisto).

          Diversity and distribution of Satyrinae butterflies (Lepidoptera: Nymphalidae) in the Coello river basin, Colombia. We describe the patterns of diversity and distribution of the subfamily Satyrinae in the Coello river basin (4º 17’ 08’’ N - 74º 35’ 36’’ W; 1 899.31 km²) from 433 to 3 600 m. Eleven sampling stations were located, in several ecosystems. The samples were collected during a period of 11 days, in March, May, July and October 2003, in three types of habitat (forest, forest edge and meadow). We collected at random, between 09:00 and 15:00 hr, using entomological nets. A total of 239 individuals (13 genera, 34 species) were collected. The most abundant species were in the genus Pedaliodes (41.4 %). Richness and diversity had high values in mountainous zones and paramo (> 2 000 m). The greater diversity was measured in the forest edge. The similarity analysis produced two groups: species from warm (Euptychia hesione and Hermeuptychia hermes) and middle (Pseudohaetera hypaesia and Taygetis celia) climate zones; and species from mountain and paramo (Lymanopoda obsoleta, Pedaliodes polusca and Eretris calisto).

          The elevational gradient in altitudinal range: an extension of Rapoport's latitudinal rule to altitude.

          G Stevens (1992)
          For trees, mammals, birds, reptiles, insects, and amphibians, the species richness on mountaintops is generally less than that of lowland areas. Coincident with this decline in species richness with increasing elevation is an increase in the altitudinal range of species. This pattern is analogous to the relationship between the latitudinal range of species and latitude (Rapoport's latitudinal rule). Both of these Rapoport phenomena, the latitudinal and the new elevational rule discussed here, can be explained as being results of differences in the breadth of climatic conditions organisms experience along the geographical gradients. The influence of latitudinal or altitudinal range size on local species richness is poorly understood, but the tendency for range margins to fall in species-rich, rather than species-poor, areas may mean that species-rich communities contain many species that are maintained only through immigration. The presence of these persistent but locally non-self-maintaining populations may explain the increased number of species found in rich communities as compared to species-poor communities without the need to invoke other differences in local species interactions.
