Digestive Phenotypic Flexibility in Post-Metamorphic Amphibians: Studies on a Model Organism
(Sociedad de Biología de Chile, 2004)
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 ...
Physiological and microbial adjustments to diet quality permit facultative herbivory in an omnivorous lizard
(Company of Biologists, 2016-06)
While herbivory is a common feeding strategy in a number of vertebrate classes, less than 4% of squamate reptiles feed primarily on plant material. It has been hypothesized that physiological or microbial limitations may ...
The association between breast density and gut microbiota composition at 2 years post-menarche: a cross-sectional study of adolescents in Santiago, Chile
(Frontiers Media, 2021)
The gut microbiome has been linked to breast cancer via immune, inflammatory, and hormonal mechanisms. We examined the relation between adolescent breast density and gut microbial composition and function in a cohort of ...
Plasticity in food assimilation, retention time and coprophagy allow herbivorous cavies (Microcavia australis) to cope with low food quality in the Monte desert
(Elsevier Inc, 2010-03)
Energy balance depends on the efficiency with which organisms make use of their trophic resources, and has direct impact on their fitness. There are environmental variations that affect the availability as well as the ...
Physiological flexibility in the Andean lizard Liolaemus bellii: seasonal changes in energy acquisition, storage and expenditure
(Springer, 2008)
According to the "barrel model", an organism may be represented by a container, with input energy constraints (foraging, digestion, and absorption) symbolized by funnels connected in tandem, and energy outputs (maintenance, ...
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 ...
Gut size flexibility in rodents: what we know, and don't know, after a century of research
(Sociedad de Biología de Chile, 2008)
Residence time distribution in holding tubes using generalized convection model and numerical convolution for non-ideal tracer detection
(ELSEVIER SCI LTD, 2010)
A procedure is proposed for the determination of the residence time distribution (RTD) of curved tubes taking into account the non-ideal detection of the tracer. The procedure was applied to two holding tubes used for milk ...
