Abstract:

A list of bee species recorded in the Caatinga region is presented, including literature and new data. Caatinga is a xerophilous vegetation characteristic of the semi-arid region of Northeastern Brazil. The species richness of its bee fauna is comparatively low with about 187 species and 77 genera (114 species and 45 genera of Apidae, 35 and 9 of Megachilidae, 18 and 7 of Halictidae, 13 and 9 of Colletidae, and 8 and 7 of Andrenidae). Some genera, that are well diversified and relatively common in the Cerrado, an adjacent but more humid biome also characterized by open vegetation, are not recorded or rare in the Caatinga, e.g. Epicharis, Monoeca, Paratetrapedia and Tetrapedia. By contrast the genera Diadasina, Melitoma and Leiopodus are relatively well diversified in the Caatinga.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
