Light-related photosynthetic characteristics of lotic macroalgae
(Kluwer Academic Publ, 2004-09-01)
Photosynthetic characteristics in response to irradiance were analysed in 42 populations of 33 macroalgal species by two distinct techniques (chlorophyll fluorescence and oxygen evolution). Photosynthesis-irradiance (PI) ...

In the present study, specimens of Anacroneuria (Plecoptera: Perlidae) from the Mucugê Municipal Park, Bahia State, Brazil were studied. The association between Anacroneuria bahiensis nymph and adult was possible because ...
Comparative study of the chemical composition, fatty acid profile, and nutritional quality of Lophiosilurus alexandri (Siluriformes: Pseudopimelodidae), a Brazilian carnivorous freshwater fish, grown in lotic, lentic, and aquaculture environments
(Soc Brasileira Ictiologia, 2019-01-01)
Lophiosilurus alexandri is a carnivorous freshwater fish endemic of Sao Francisco basin and an endangered species. In this study, we analysed the chemical composition (moisture, protein, ash and lipid), fatty acid profile, ...
Evidence on Night Movements of Macroinvertebrates to Macrophytes in a Pampean Stream
(Scientific Research Publishing, 2014-07)
Nocturnal invertebrate abundance peaks in lotic systems are usually associated to drift, however, diel migrations other than drift may be important in slow-flowing systems. Then, macroinvertebrate distribution on macrophytes ...
