Collembolans are small hexapods characterized by the presence of a ventral tube
and a jumping organ known as a furcula, for which they are called springtails. Although
more than 700 species are recorded from the Neotropics, ...
Potential of fungal endophytes from Thalassia testudinum Bank ex K.D. Koenig as producers of bioactive compounds.
(2008)
Sea grass beds of Thalassia testudinum provide an essential habitat for marine species of economic importance. Previous studies have demonstrated the presence of mycelial endophytic fungi from undamaged tissue of T. ...

Characterization and detection by In situ gene amplification of marine denitrifying bacteria
(2003)
Recent studies suggest that the oceanic nitrogen budget is unbalanced, primarily
due to a high nitrogen removal in contrast to the fixation rate. This imbalance likely
results from denitrification activity in continental ...
