Differences In Butterfly (nymphalidae) Diversity Between Hillsides And Hilltop Forest Patches In The Northern Andes

Andean montane butterflies have unique diversity patterns in each mountain system, and the knowledge on how their community diversity changes at local scale has potential important implications on designing regional conservation strategies. The multiplicative partition of the diversity and the effective number of species provides a useful tool in studying the patterns of diversity in heterogeneous Andean cloud forest habitats. Here, we evaluated diversity in three nearby sites in the Andean Central Cordillera of Colombia, two hillsides – on western (Cauca canyon) and eastern (Aburrá valley) slopes – and one hilltop. We collected a total of 1039 individuals belonging to 55 species of butterflies. Alpha diversity differs between hillsides and the hilltop. Beta diversity in the three areas show differences in richness (q0) and in diversity of the order of magnitude of q1 and q2, with the major differences between hillsides and hilltop. This study shows important differences in butterfly (Nymphalidae) assemblages on a local scale, and suggests that any efforts directed towards comprehensive protection of a given area in a heterogeneous mountain landscape must be focused on the complete forested area, not being limited to a hilltop or to a single hillside. © 2015 Taylor & Francis.503194203BIOCON08_021, Fundación BBVAAdams, M., Speciation in the pronophiline butterflies (Satyridae) of the northern Andes (1985) J Res Lepid, Suppl 1, pp. 33-49Adams, M., Pronophiline butterflies (Satyridae) of the three Andean Cordilleras of Colombia (1986) Zool J Linn Soc, 87, pp. 235-320Brehm, G., Pitki, L.M., Hilt, N., Fiedler, K., Montane Andean rain forests are a global diversity hotspot of geometrid moths (2005) J Biogeogr, 32, pp. 1621-1627Brehm, G., Süssenbach, D., Fiedler, K., Unique elevational diversity patterns of geometrid moths in an Andean montane rainforest (2003) Ecography, 26, pp. 456-466Brown, K.S., Jr., Geologic, evolutionary, and ecological bases of the diversification of neotropical butterflies: implications for conservation (2005) Tropical rainforest: past, present and future, pp. 166-201. , Bermingham E., Dick C.W., Moritz C., (eds), Chicago (IL): University of Chicago PressCasner, K.L., Pyrcz, T.W., Patterns and timing of diversification in a tropical montane butterfly genus, Lymanopoda (Nymphalidae, Satyrinae) (2010) Ecography, 33, pp. 251-259Chao, A., Chazdon, L.R., Colwell, R.K., Shen, T.-J., Abundance-based similarity indices and their estimation when there are unseen species in samples (2006) Biometrics, 62, pp. 361-371Chao, A., Colwell, R.K., Lin, C.-W., Gotelli, N.J., Sufficient sampling for asymptotic minimum species richness estimators (2009) Ecology, 90, pp. 1125-1133Chao, A., Jost, L., Chiang, S.C., Jiang, Y.-H., Chazdon, R.L., A two-stage probabilistic approach to multiple-community similarity indices (2008) Biometrics, 64, pp. 1178-1186Chao, A., Shen, T.-J., Nonparametric estimation of Shannon’s index of diversity when there are unseen species in sample (2003) Environ Ecol Stat, 10, pp. 429-443Charney, N., Record, S., (2012) Vegetarian: jost diversity measures for community data [Internet].
