R. D. Greenonservation biogeography has increasingly been using functional diversity (FD) as an alternative metric to describe how trait diversity is distributed throughout space. FD can be promptly related to the function played by species in a community, better than taxonomic diversity. Here, we mapped multi

Though biogeographical studies with anurans in South America have been continuously performed during the last decades, most of them focus on specific clades and/or regions. Moreover, no systematic compilation has been performed since the first synthesis of patter

sp3 Carbon,In view of the established opinion [7] that only compounds containing ‘activated’ C—H groups are capable of hydrogen bond formation, this compound should be one of the most favourable for such studies. Indeed, the polarity of the C—Cl bond is greater than that of the other C—halogen bonds, with the

The wavenumber of this mode (3060–3100 cm.) was found to decrease when azine or dimethyl sulphoxide was added to a CCl. solution of any of t
