Chocó-Darien is an important biogeographic realm, as it a terrestrial biodiversity hotspot and the southern limit of Caribbean reefs. However, to date there are no compiled data on reef fish assemblage this region. We provide updated checklist marine fishes from system (Colombia), with comments their geographic distribution conservation status. Peer-reviewed studies, unpublished in situ visual ...

The successive interference cancellation tree algorithm with first success (SICTA/FS) was specifically designed as a random access protocol over noisy collision channels. Given J users with an infinite buffer and subject to Poisson arrivals, SICTA/FS achieves throughputs as high as 0.6 if packet losses are allowed (up to 20%), while without packet losses its throughput quickly degrades as the n...

Fixation of (14)CO(2) by synchronized cultures of Ankistrodesmus braunii was highest for young growing cells, low for mature cells, and lowest for dividing cells. The amount of (14)C excreted during photosynthesis followed the same trend. Cells at the end of the growing phase, after 10 hours of a 16-hour light phase, excreted nearly 35% of the total (14)C fixed as one product, glycolate. Dividi...
