Despite a 1944 publication questioning the misconception that Eastern Spadefoots (Scaphiopus holbrookii) and other Scaphiopodidae are ‘secretive’ outside of rain-induced migration and breeding aggregations, confirmation bias has perpetuated this fallacy. As a result, S. holbrookii is one of the least studied frogs in the United States. Amassing a large

MORPHOLOGICAL DIFFERENTIATION OF EASTERN SPADEFOOT TOAD (PELOBATES SYRIACUS) POPULATIONS
Israel Journal of Zoology, 2002We studied morphological differentiation of the eastern spadefoot toad (Pelobates syriacus) in fourteen population samples from Serbia, Macedonia, Bulgaria, and Turkey.

Abstract The eastern spadefoot toad ( Scaphiopus holbrookii ) is listed as endangered in Connecticut, having only one viable population in the state. Efforts to investigate their distribution in Connecticut are frustrated by their rarity, as well as their nocturnal and fossorial habits.

Conservation Genetics Resources, 2010
We isolated and characterized 10 microsatellite loci from the eastern spadefoot toad, Scaphiopus holbrookii. Loci were screened in 24 individuals from two schools of tadpoles in a single isolated wetland in South Carolina, USA. The number of alleles per locus ranged from 4 to 12, observed heterozygosity ranged from 0.200 to 0.875, and the probability ...

Copeia, 2013
The way animals allocate resources to growth and reproduction is of major importance in understanding life-history trade-offs. Because the investment in reproduction of the two sexes differs, comparing the costs and the reproductive strategies adopted offers an insight into the evolutionary forces that shaped them.

Amphibia-Reptilia, 2010
AbstractAmphibians exhibit plasticity in the timing of metamorphosis, and tadpoles of many species respond to pond drying by accelerating their development. In the present study we investigated the phenotypic plasticity of the developmental response to water volume reduction in tadpoles of Eastern spadefoot toad Pelobates syriacus.

Molecular Ecology, 2010
AbstractSeveral hypotheses are available to predict change in genetic diversity when approaching peripheral populations. We used the eastern spadefoot toad in Israel as a model system to examine these hypotheses using population genetics analyses and network theory. Our results contradicted most of the predictions from the ‘abundant centre’ model, that

Abstract There is a paucity of empirical results regarding many aspects of the movement ecology and upland habitat use and preferences of the Eastern Spadefoot Toad (Scaphiopus holbrookii), an ephemeral, wetland-breeding anuran that is rare throughout a number of states in the northern portion of its range.

Abstract Eastern Spadefoots (Scaphiopus holbrookii) are probably one of the least-understood amphibian species in the United States. In New England, populations are localized and it is likely that some populations go undocumented because of the species' cryptic habits.
