(2006)
Digit length ratios are organized during embryonic development and may show sexual dimorphism related to steroid exposure. The second-to-fourth digit length ratio (2D:4D) has received the most attention. In the present ...
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). ...
Fresh biochar application provokes a reduction of nitrate which is unexplained by conventional mechanisms

(2017)
Panama is still far from completing its orchid flora inventories, where large genera such as Lepanthes (Pleurothallidinae) reveal novelties regularly. Here, we describe and illustrate two new species of Lepanthes. Lepanthes ...
Genetic diversity in the endangered tropical tree, Guaiacum sanctum (Zygophyllaceae)
