Larval Adaptation to Salinity Shock in Cane Toads (Rhinella marina) From Coastal French Guiana [PDF]
Many habitats not only differ in mean conditions but also in the degree to which these conditions fluctuate through time. Therefore, local adaptation to both mean abiotic conditions and habitat variability can enhance organismal viability.

Editors' Note: Dr. Egan inquires about the possibility of Tournay phenomenon in Kawasaki and Mayer's "Tadpole pupil." Dr. Charles, in reference to "Disease-modifying drugs for multiple sclerosis in pregnancy: A systematic review," suggests that it might be appropriate to continue glatiramer acetate in women trying to conceive given the lack of evidence

The trade-off between offspring size and number is central to life history strategies. Both the evolutionary gain of parental care or more favorable habitats for offspring development are predicted to result in fewer, larger offspring.

Polyculture of bullfrog tadpoles and Nile tilapia fry
Two experiments were carried out to test better stocking proportion according to animal size for tilapia (Oreochromis niloticus) and tadpole (Lithobates catesbeianus).

Is hypoxia a stressor to American bullfrog tadpoles? [PDF]
The aim of this study was to evaluate alterations to the physiological profile of cortisol in pro-metamorphose phase tadpoles of Lithobates catesbeianus exposed to hypoxia stressor in a capture experiment and in a crowding experiment.

Evaluation of the Effect of Ecological Factors on Cannibalism in Pelophylax bedriagae (Pallas, 1771) (Amphibia: Anura) [PDF]
Marsh frog, Pelophylax bedriagae tadpoles habituate in temporary wetlands where intraspecific aggression has been observed. In this study, we examined the independent and interactive effects of predator cues, water level and density on head width size ...

Abstract We examine the mechanism of moduli stabilization by fluxes in the limit of a large number of moduli. We conjecture that one cannot stabilize all complex-structure moduli in F-theory at a generic point in moduli space (away from singularities) by fluxes that satisfy the bound imposed by the tadpole cancellation condition ...

The Tadpole Pupil: Case Series With Review of the Literature and New Considerations
Tadpole pupil is a rare phenomenon in which segmental spasm of the iris dilator muscle results in a tadpole-shaped pupil. The pupillary distortion is usually unilateral, lasts several minutes, and can recur in clusters.
