.... Moreover, changes in movement parameters also cause changes in the dynamics of self-generated sensory stimuli, to which motion-detecting sensory systems have to adapt. Here, we examined head movements and swimming kinematics of Xenopus laevis tadpoles with a body length of 10–45 mm (developmental stage 46...

... to DTFs, tadpoles from habitats characterised by small DTFs would show greater plasticity in the thermal sensitivity of physiological processes than tadpoles from environments characterised by large DTFs. We tested the thermal sensitivity of physiological traits in tadpoles of three species that differ...

... during feeding. We used high-speed digital imaging (500 Hz) to observe tadpoles of six species from the anuran family Hylidae grazing on a standardized food-covered substrate. Tadpoles of these species vary in the number of labial tooth rows, belong to two different feeding guilds (benthic and nektonic...

...Brian P. Schmidt; Jeffrey M. Knowles; Andrea Megela Simmons SUMMARY Current flow is an important biological stimulus for larval anuran amphibians, but little is known about how it is perceived. We quantified behavioral responses to controlled water flow in the bullfrog tadpole ( Rana catesbeiana...

... not differ between tadpoles raised in stable or variable thermal conditions. Furthermore, the Q 10 values of each response variable were virtually unaffected by treatment when measured over the entire thermal range. Our results reveal that larval amphibians exhibit little plasticity in metabolic traits...

... of a pair of giant reticulospinal neurons in fish and amphibians. In support of the involvement of a Mauthner neuron, unilateral lesions of the caudal hindbrain eliminated escape activity on the operated side, but activity remained on the un-operated side. Behaviourally, tadpoles responded to temperature...

... of NO on the cardiac-like impulse generated by skin cells of the hatchling Xenopus tadpole. Skin cell impulses propagate from cell to cell via gap junctions and form an unusual sensory system, which triggers escape behaviour at early stages of amphibian development. We show that the NO donor S-nitroso- N...

...MARTIN E. FEDER; RICHARD J. WASSERSUG Tadpoles of Xenopus laevis Daudin can extract oxygen from both air and water. When these larvae have access to air, aerial oxygen uptake averages 16.6% of total oxygen consumption in normoxic water, and increases to 100% of net oxygen consumption in hypoxic...
