The phrase "amphibians involves the" is not correct in written English due to subject-verb agreement issues.
It can be used in a context discussing the involvement of amphibians in a particular process or study, but it needs to be rephrased for grammatical accuracy.
Example: "The study of ecosystems often involves the role that amphibians play in maintaining biodiversity."
Alternatives: "amphibians are involved in" or "the involvement of amphibians in".
Larval development towards the completion of metamorphosis in amphibians involves two directional processes: growth in body size and the differentiation and remodeling of tissues and organs [17].
Folding of the brain in amphibians involves progressive apical constriction coordinated with changes in cell height.
This transformation of the larval intestine to the adult form during amphibian metamorphosis involves the removal of larval epithelium and de novo formation of the adult epithelium with concurrent maturation of the other intestinal tissues in a process similar to the maturation of the mammalian intestine around birth [ 1– 5].
Mechanisms underlying road effects on amphibians involve direct mortality, behavioral barriers to movement, and reduction in the quality of roadside habitats.
Most tests for Bd in native amphibians involved animals caught in traps set in water for X. laevis.
The buccal pump mechanism, which involves the pushing of air between the lungs and the closed mouth, is present in amphibians and some groups of fishes.
In the case of progress and evolution, these might involve the examples cited above of how amphibians and reptiles benefit from an incompletely divided heart, or the fact that skulls and spines have become simpler rather than progressively more complex.
The final two phases involve the use of fish/amphibian and mammalian in vivo models.
Recent microarray analyses of anurans and salamanders show that amphibian metamorphosis involves thousands of gene expression changes, involving many biological processes that have previously received little attention [ 9, 10].
Because of the general structural similarity with other amphibian glands involved in pheromone production, the gular gland of hyperoliids is likely to serve a similar function; however, the mode of transmission remains unclear so far, and will be experimentally tested in future studies.
