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.

Bioaccumulation, Ecotoxicity, and Microbial Responses in Hoplobatrachus rugulosus Tadpoles Following Co-Exposure to Imidacloprid and Microplastics [PDF]
Agricultural organic pollutants have been identified as a key factor contributing to amphibian population decline, particularly during early developmental stages when tadpoles are frequently exposed to neonicotinoids (NEOs) and microplastics (MPs).

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.

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 ...

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.

The tadpole conjecture proposes that complex structure moduli stabilisation by fluxes that have low tadpole charge can be realised only at special points in moduli space, leading generically to (large) gauge symmetries.

Tadpole versus anomaly cancellation in D=4,6 compact IIB orientifolds [PDF]
It is often stated in the literature concerning D=4,6 compact Type IIB orientifolds that tadpole cancellation conditions i) uniquely fix the gauge group (up to Wilson lines and/or moving of branes) and ii) are equivalent to gauge anomaly cancellation. We
