A Comparison of four Methods to Evaluate the Butterfly Abundance. Using a Tropical Community
(Journal of the Lepidopterists' Society 45(3), 1991, 241-243, 1991-03-18)In recent years. several transect methods to evaluate the abundance of butterflies have been proposed (Pollard, E. 1977, Biol. Conserv. 12:115—134; Feltwell, 3. 1982. Proc. Trans. Br. Entomol. Nat. Hist. Soc. 15:17—24). ... -
A genome‐wide quantitative trait locus (QTL) linkage scan of NEO personality factors in Latino families segregating bipolar disorder
(2017)Personality traits have been suggested as potential endophenotypes for Bipolar Disorder (BP), as they can be quantitatively measured and show correlations with BP. The present study utilized data from 2,745 individuals ... -
