| Summary: | We present the geographical and altitudinal distribution of the Gerridae family on the western slopes of the Western Cordillera of Andes in southwestern Colombia. The specimens were captured in different water bodies, eight sampling sites, during 2009 and 2010. Taxonomic composition was analyzed with respect to geographical and altitudinal range, biomes and the similarity between areas. The geographical distribution of the Gerridae is related to geographic area, foothills and Plain Pacific, altitudinal range (0-2000 masl) and features of type of biome. The communities of Gerridae from Pacific Plain are in the same zonobioma but differ in taxonomic composition due to differences in water bodies and microhabitats own. On the other hand we show the inverse relationship between altitude and species richness.
ANÁLISIS DE LA DISTRIBUCIÓN GEOGRÁFICA DE LAS GERRIDAE (HEMIPTERA, GERROMORPHA) EN LOS ANDES DEL SUROESTE DE COLOMBIA
Se presentan la distribución geográfica y altitudinal las Gerridae en la vertiente occidental de la Cordillera Occidental, suroccidente de los Andes de Colombia. La captura de especimenes se realizó en cuerpos de agua en ocho sitios de muestreo, durante los años 2009 y 2010. Se analizó la composición taxonómica respecto al rango geográfico y altitudinal, los biomas y la similitud entre áreas. La distribución geográfica de las Gerridae esta relacionada con el área geográfica, rango altitudinal (0-2000m) y tipo de bioma. Las especies de la Planicie del Pacífico a pesar de encontrarse en el mismo Zonobioma difieren en su composición taxonómica debido a diferencias en los cuerpos de agua y michohábitats característicos. Se evidencia la relación inversa entre la altitud y la riqueza de especies. |
