Effects of mosquitofish (Gambusia affinis) cues on wood frog (Lithobates sylvaticus) tadpole activity

open access: yesActa Herpetologica, 2011
We examined the changes in activity of wood frog (Lithobates sylvaticus) tadpoles exposed to combinations of visual, chemical, and mechanical cues of the invasive mosquitofish (Gambusia affinis).

Making friends: social attraction in larval green and golden bell frogs, Litoria aurea. [PDF]

open access: yesPLoS ONE, 2013
Socio-ecological models combine environmental and social factors to explain the formation of animal groups. In anurans, tadpole aggregations have been reported in numerous species, but the factors driving this behaviour remain unclear.

LOCAL TADPOLE GALAXIES [PDF]

open access: yesThe Astrophysical Journal, 2012
Tadpole galaxies have a giant star-forming region at the end of an elongated intensity distribution. Here we use SDSS data to determine the ages, masses, and surface densities of the heads and tails in 14 local tadpoles selected from the Kiso and Michigan surveys of UV-bright galaxies, and we compare them to tadpoles previously studied in the Hubble ...

Metamodulation of a spinal locomotor network by nitric oxide [PDF]

open access: yes, 2004
Flexibility in the output of spinal networks can be accomplished by the actions of neuromodulators; however, little is known about how the process of neuromodulation itself may be modulated.

The development of free-swimming in Xenopus laevis larvae [PDF]

open access: yes, 2013
In Xenopus laevis frog tadpoles, highly self-motive, free-swimming behaviour emerges at the onset of feeding. This is in contrast to the earlier post-hatched larval form, which is capable of escape swimming when stimulated, but normally lies dormant.

Behavioral responses of tadpoles of Duttaphrynus melanostictus (Anura: Bufonidae) to cues of starved and fed dragonfly larvae

open access: yesPhyllomedusa: Journal of Herpetology, 2020
Behavioral responses of tadpoles of Duttaphrynus melanostictus (Anura: Bufonidae) to cues of starved and fed dragonfly larvae. Tadpoles of Duttaphrynus melanostictus use chemoreception to detect kairomonal cues and excretory metabolites from predatory ...

Antipredator pheromones in amphibians: a review

open access: yesVeterinární Medicína, 2006
Specific chemosignals (pheromones) have an important role in the antipredator behaviour in amphibians and other vertebrates. However, relatively little is known about the occurrence of chemical alarm cues just in amphibians.

Distribution of tadpoles of large wrinkled frog Nyctibatrachus major in central Western Ghats: influence of habitat variables

open access: yesActa Herpetologica, 2009
The relationship between habitat variables and the distribution and abundance of adults and tadpoles of Nyctibatrachus major (large wrinkled frog) in 35 forest streams in central Western Ghats is detailed in this paper.

Bilateral tadpole pupils [PDF]

open access: yesNeurology, 2016
A 19-year-old man with congenital erythropoietic protoporphyria and without family history or prior migraine attacks had recurrent seizures, which were controlled on propofol. Eye examination performed while awake revealed nonreacting bilateral tadpole pupils (TPs) (figure), without other neurologic deficits.

Spatio‐Temporal Assessment of Fish Biodiversity in High‐Density Cascade Dam Rivers Using Environmental DNA Metabarcoding

open access: yesBiological Diversity, EarlyView.
This study employed eDNA technology for biodiversity surveys and conducted high‐density spatiotemporal eDNA sampling to evaluate ecosystem‐scale patterns across temporal, spatial, and habitat dimensions. We identified 97 fish species from 12 orders, 29 families, and 71 genera using eDNA technology. Spatially, fish diversity indices were correlated with
