The present study analyzed the composition of the aquatic fauna associated to the mangrove forest in a southeastern Brazilian river. The composition of the macrofauna in the roots of the marginal vegetation located at three ...
Arbuscular mycorrhizae and dark-septate endophytes on Atriplex cordobensis in saline sites from Argentina
(Thammasat University Press, 2012-11)
Atriplex cordobensis occurs in salt works and saline soils of northern and central Argentina and is utilized as a forage source; however the mycorrhizal status of this salt bush is unknown. We studied the arbuscular ...
Neoformation of micas in soils surrounding an alkaline-saline lake of Pantanal wetland, Brazil
(ELSEVIER SCIENCE BV, 2010)
The mineralogy and origin of micas were investigated in incipient soils surrounding a modem alkaline-saline lake of Nhecolandia, a sub-region of Pantanal wetland. Soils were sampled along a toposequence and analyzed by ...
Distribution related to temperature and salinity of the shrimps Acetes americanus and Peisos petrunkevitchi (Crustacea: Sergestoidea) in the south-eastern Brazilian littoral zone

Influence of regional factors on zooplankton structure in a saline lowland river: the Salado River (Buenos Aires province, Argentina)
(Wiley, 2008-08)
Knowledge of regional factors influencing zooplankton structure in a semiarid river must include both the main channel and any tributaries in order to identify spatial and temporal patterns along with the main factor that ...
Occurrence and distribution of plankton-associated and free-living toxigenic Vibrio cholerae in a tropical estuary of a cholera endemic zone
(Springer, 2012-01)
Cholera epidemics are thought to be influenced by changes in populations of estuarine Vibrio cholerae. We investigated the abundance and distribution of this bacterium, as ‘‘free-living’’ (\20 lm fraction) and associated ...
