The venomous secrets of the web droplets from the viscid spiral of the orb-weaver spider Nephila clavipes (Araneae, Tetragnatidae)
(Wiley-Blackwell, 2006-01-01)
The capture web of N. clavipes presents viscous droplets, which play important roles in web mechanics and prey capture. By using scanning and transmission electron microscopy, it was demonstrated that the web droplets are ...
Ontogenetic shifts in the digestive tube and diet of Bryconamericus stramineus Eigenmann, 1908 (Osteichthyes, Characidae)
(2009-01-01)
Aim: Studies on feeding of early life stages are very important to the understanding of the biology and trophic ecology of fish species. Therefore, the aim of this work is to describe the development of the digestive tube, ...

(Biomed Central Ltd, 2015)
The role of multiple partners in a digestive mutualism with a protocarnivorous plant
(2013-01-01)
Background and aimsThe protocarnivorous plant Paepalanthus bromelioides (Eriocaulaceae) is similar to bromeliads in that this plant has a rosette-like structure that allows rainwater to accumulate in leaf axils (i.e. ...
Size-related shifts in dietary composition of Centropomus parallelus (Perciformes: Centropomidae) in an estuarine ecosystem of the southeastern coast of Brazil
(Wiley-Blackwell, 2009-06-01)
Size-related and seasonal evaluation of the dietary composition of fat snook (Centropomus parallelus Poey 1860) in the upper sector of an estuary of the southeastern coast of Brazil were carried out based on stomach analyses ...
Insect/Bt-cotton interactions: Are immunological variables and hemocyte ultrastructure in Podisus nigrispinus (Hemiptera: Pentatomidae) affected?
(2013-04-01)
Recent studies have shown that ingestion by the army worm Spodoptera frugiperda of Cry1Ac toxin from Bt cotton promotes histochemical and ultrastructural changes in the digestive cells of the predatory pentatomid bug Podisus ...
Enzymatic toxins from snake venom: structural characterization and mechanism of catalysis
(Wiley-Blackwell, 2011-12-01)
Snake venoms are cocktails of enzymes and non-enzymatic proteins used for both the immobilization and digestion of prey. The most common snake venom enzymes include acetylcholinesterases, l-amino acid oxidases, serine ...
Suplementação de enzimas exógenas em dieta microparticulada para larvicultura do pacu
(Sociedade Brasileira de Zootecnia, 2006-12-01)
Este experimento foi realizado para avaliar os efeitos da suplementação de enzimas exógenas (pancreatina suína) em microdietas sobre o crescimento, a sobrevivência e as alterações morfológicas do trato digestório de larvas ...
