Effects of macrophyte architecture and leaf shape complexity on structural parameters of epiphytic algal community in a Pampean stream
(Springer, 2013-08-10)
Habitat heterogeneity is one of main factors determining distribution of organisms, and vegetation is of primary importance in shaping structural environment in aquatic systems. The effect of macrophyte complexity on ...

Forest management intensity affects aquatic communities in artificial tree holes
(Public Library of Science, 2016-05)
Forest management could potentially affect organisms in all forest habitats. However, aquatic communities in water-filled tree-holes may be especially sensitive because of small population sizes, the risk of drought and ...
Structure and variation of the Paraguay River phytoplankton in two periods of its hydrological cycle
(Springer, 2002-03)
The structure and distribution of the Paraguay River phytoplankton (between 16° 03′ and 26° 53′ S and between 57° 13′ and 58° 23′ W was studied during June-July/95 and December/95-January/96. Phytoplankton density values ...
Floral visitor assemblages related to coriander genotypes and sowing dates: relationship with volatile signals
(Elsevier, 2017-12)
Intraspecific diversity of crops producing volatile organic compounds could harbor different assemblages of flower visiting insects, improving agricultural landscape heterogeneity and thus, natural regulation of crop pests. ...
