Changes in lactate dehydrogenase isozyme pattern during the developement of Xenopus laevis (Daudin)

Nitrogen excretion in the tadpoles of Xenopus laevis Daudin.

Botulinum C3 enzyme changes the lactate dehydrogenase isozyme pattern of primary culture of neurons.

Changes in the lactate dehydrogenase (LDH) isozyme pattern of primary culture of neurons treated with botulinum C3 enzyme were examined in order to elucidate the functional changes accompanying the morphological change that follows ADP-ribosylation of Rho protein. Primary neurons were prepared from the cerebrum of ICR mouse embryos on day 15. Neurons were cultured in MEM with 10% fetal calf ser...

The lateral line system at metamorphosis in Xenopus laevis (Daudin).

Marked changes in the anatomy of the lateral line system occur during the metamorphosis of Xenopus. The distribution of rows differs in larva and adult and the orientation and number of organs are modified at metamorphosis. Larval plaques are functional, as shown by recording from their nerves. Two classes of cells with polarized cilia are present in the tadpole well before the orientation of i...

Diet of feral Xenopus laevis (Daudin) in South Wales, U.K

African clawed frogs (Xenopus laevis) in a South Wales pond ate a wide variety and size range of prey. Zoobenthos and zooplankton made the greatest contribution to diets, both numerically and by weight. Terrestrial invertebrates made up a small proportion of the diet numerically but a large proportion of the diet mass during the spring and summer. Nektonic prey were present throughout the year ...

Invasive Populations of Xenopus Laevis (daudin) in Chile

Invasive populations of Xenopus laevis are known from the UK, USA and Chile, although there is poor documentation of the latter. Currently, four administrative Regions in Chile are reported as having established populations. Fieldwork during the austral winter of 2001 was conducted in order to assess the density and diet of X. laevis populations in two localities. At one site, fewer than 30 adu...
