Afr J Ecol 46:3–13Īlmaraz-Almaraz ME, León-Cortés JL, Molina-Martínez A (2013) The population ecology and conservation of Pterourus esperanza (Insecta: Lepidoptera): an ancestral swallowtail butterfly in the Northern Sierra of Oaxaca, Mexico. It is a matter of urgency that should put in place monitoring schemes to assess occupancy and change so we can assess changes in the status of butterfly species in rapidly-expanding urban landscapes in tropical Mexico.Īkite P (2008) Effects of anthropogenic disturbances on the diversity and composition of the butterfly fauna of sites in the Sango Bay and Iriini areas, Uganda: implications for conservation. Furthermore, canonical correspondence analyses suggested significant associations for the values of butterfly abundance and microhabitat variables such as canopy cover, open areas, presence of grasses, bare soil or rocks. This was confirmed by IndVal analyses from which we identified 39 butterfly species as potential reliable land-cover indicators. Logistic regression analyses suggested that species with narrow geographic ranges could be associated to cloud-forest sites, and that species with relatively more widespread distributions in the Neotropics were more likely to be classified as occurring in mountain wetland habitats. A rarefaction curve analysis for local richness indicated that mountain wetland sites recorded the highest butterfly diversity. In total, we recorded 3630 individuals from 90 species at key sites spanning natural, semi-natural and urban areas. ![]() Cloud forest exhibited a minor positive expansion in area, mostly through forest regeneration. Between 20, mountain wetlands, secondary forest, and agro-pasture land, have declined significantly in area covered due to increasing housing activities and expansion of roads and conversion of land for cattle activity. Redistribution, derivative work, commercial use, and all other use is permitted.We examined the relationship between landscape structure and composition, geographic ranges, microhabitat characteristics and the diversity of butterflies (Papilionidae, Nymphalidae, Pieridae, Hesperiidae, Lycaenidae) in an expanding urban landscape in the highlands of Chiapas, Mexico. ![]() The copyright holder of this file allows anyone to use it for any purpose, provided that the copyright holder is properly attributed. ![]() High-resolution photos may be licensed from the Oregon State Archives.Īll photos from the collection are found in the source-category Category:Images from Oregon Historical County Records Guide.
