Digestive morphology and enzyme activity in the Andean toad Bufo spinulosus: Hard-wired or flexible physiology?
(Elsevier Inc., 2005)
Gut plasticity is a trait with implications on animal performance. However, and despite their importance as study models in physiology, research on gut flexibility in amphibians is scarce. In the present work, we analyse ...
Individual diet specialisation in sparrows is driven by phenotypic plasticity in traits related to trade-offs in animal performance
(Blackwell Publishing Ltd, 2019)
© 2018 John Wiley & Sons Ltd/CNRS Individual diet specialisation (IS) is frequent in many animal taxa and affects population and community dynamics. The niche variation hypothesis (NVH) predicts that broader population ...
Phenotypic flexibility in the intestinal enzymes of the African clawed frog Xenopus laevis
(ELSEVIER SCIENCE INC, 2005-01)
The intestinal plasticity of digestive enzymes of amphibian species is poorly known. The goal of this study was to characterize digestive enzyme profiles along the small intestine of adult frogs, Xenopus laevis, in response ...
Are levels of digestive enzyme activity related to the natural diet in passerine birds?
(SOC BIOLGIA CHILE, 2011)
Digestive capabilities, such as the rates nutrient hydrolysis and absorption, may affect energy intake and ultimately feeding behavior. In birds, a high diversity in gut biochemical capabilities seems to support the existence ...
Digestive morphology and enzyme activity in the Andean toad, Bufo spinulosus: hard-wired or flexible physiology?
(ELSEVIER SCIENCE INC, 2005-02)
Gut plasticity is a trait with implications on animal performance. However, and despite their importance as study models in physiology, research on gut flexibility in amphibians is scarce. In the present work, we analyse ...
Simulation of Human Small Intestinal Digestion of Starch Using an In Vitro System Based on a Dialysis Membrane Process
(MDPI, 2020)
This work deepens our understanding of starch digestion and the consequent absorption
of hydrolytic products generated in the human small intestine. Gelatinized starch dispersions were
digested with -amylase in an in ...
Digestive and metabolic flexibility allows female degus to cope with lactation costs
(UNIV CHICAGO PRESS, 2008-11-01)
Lactation is the most energetically demanding period in the life
cycle of female mammals, and its effects on digestive flexibility
and the size of internal organs have been extensively studied in
laboratory mice and ...
Membrane-bound intestinal enzymes of passerine birds: Dietary and phylogenetic correlates
(2011)
Bird species exhibit great diversity in digestive tract morphology and enzymatic activity that is partly correlated with the chemical composition of their natural diets. However, no studies have assessed whether the ...
Morphophysiological aspects of the digestive tract in IV stage larvae of Bradysia impatiens (Diptera: Sciaridae).
(Universidad del ValleColombia, 2019-12-31)
The morphological, cytological and physiological aspects of the digestive tract of the siarid Bradysia impatiens fourth-instar larvae were studied using bright-field microscopy. The division of the digestive tract into the ...
Ontogenic development of intestinal disaccharidases in the precocial rodent Octodon degus (Octodontidae)
(Elsevier Inc., 2003)
We studied the ontogeny of the intestinal brush border disaccharidases sucrase and lactase in the precocial rodent Octodon degus. Sucrase hydrolyze sugars from plants while lactase hydrolyzes sugars from milk. Enzyme ...
