Estructura de las comunidades de lepidopteras en función de variables climáticas y hábitat natural y antrópico mediante análisis de interdependencia, Altos Mirandinos Venezuela, 2013.

Abstract

The objective was to discriminate, through interdependent techniques, the change in the structure of the lepidoptera communities based on climatic variables, natural and anthropic habitat in Altos Mirandinos Venezuela, 2013. The Lepidoptera are reliable guides to the state and diversity of the environment. However, the constant climatic changes and the anthropic behavior have become influential factors of the presence of the communities of these living beings. The information provided was obtained through a direct search with a manual entomological network, resulting in the discovery of 1680 Lepidoptera. The taxon with the highest abundance of Lepidoptera was Nymphalidae (50.5%), and the month with the highest presence of Lepidoptera was March (19.8%). The interdependence techniques used were principal components analysis, correspondence analysis and mixed factorial analysis. The Principal Component Analysis (PCA) showed that the first two components explain 92% of the variability of the information demonstrating a relationship between the climate and the presence of the Lepidoptera, on the other hand the Correspondence Analysis (CA) concluded that the only variable that discriminates the abundance of Lepidoptera is the changeable month, finally the Mixed Factorial Analysis showed a factor 1 called meteorological elements with the variables temperature, humidity and rainfall, and a factor 2 called atmospheric phenomena grouped into the variables atmospheric pressure, burst of wind and average wind speed; However, the habitat did not provide more information about the concurrence of these insects, despite the changeable weather, family (Papilionidae) and host (in flight) reflected the variability of their presence. Additionally, the importance of carrying out more studies with statistical support in the ecological area is highlighted as these studies will allow the implementation of strategies and policies that include the conservation of different insects.
