We analyzed the diversity of geometrid moths in the Chilean Coastal Range, between the Copiapó river and Chiloé Island. The distribution patterns of the species were studied by analyzing endemicity under the optimization criterion, using the NDM / VNDM software. Eleven endemism areas recovered, and grouped into 5 consensus areas, which were conside...

Conservation efforts should be focused on the most threatened species and their habitats; frequently, these species are endemic to small areas. We conducted a review of vascular plants, vertebrates and some orders of invertebrates that are endemic to the ecosystems of the Temperate Chilean Coastal forests. We established that 45 species of vascular...

In the more developed Pterygotas, such as Lepidoptera, the sternal apophyses are much closer and they tend to be held by a medium inflection of the sternum (the furca). In this way, the coxas (cx) become more ventral than in the original condition. Using the metafurcasternum as a morphological character is restricted as a phylogenetic relationship...

Although the degree of mate competition, given extreme differences in sex ratio, explains much of the pattern of male-biased size dimorphism among diverse taxa, it fails for some species which have potential for intense male competition for mates and yet exhibit little or no sexual size dimorphism (SSD). This fact suggest that species with low SSD...

Full-text available
Bees and wasps could exhibit shape and size sexual dimorphism, and most of their morphological variation could depend on phenotypic responses due to environmental pressure during ontogenetic development. More complex measurement techniques related to size and shape rather than simply to mass and length should be required to analyze such a complex s...

When the environmental conditions change locally, the organisms and populations may also change in response to the selection pressure, so that the development of individuals may become affected in different degrees. There have been only a few studies in which the patterns of wing morphology variation have been looked into along a latitudinal gradie...

Insects in many species vary greatly in the expression of secondary sexual traits, resulting in sexual dimorphism, which has been proposed to be a consequence of differences in sexual selection. In this study, we analyze the occurrence of sexual shape dimorphism and the correlation between geometric body size in males and females and sex ratio in t...
