Annual climatic fluctuations and short-term genetic variation in the eastern spadefoot toad [PDF]

open access: yesScientific Reports, 2021
In addition to variations on the spatial scale, short- and long-term temporal variations, too, can impose intense selection on the overall genetic diversity and composition of a population.

Herpetofauna Richness, Diversity, and Occurrence at the Northern Ecotone of Longleaf Pine. [PDF]

open access: yesEcol Evol
The longleaf pine ecosystem is recognized for its value in providing habitat to a variety of specialist and endemic species, especially herpetofauna; however, at the northernmost ecotone of longleaf pine (in southeastern Virginia) little is known about the denizen reptiles and amphibians.

Competition's Role in Shaping Cryptic Genetic Variation. [PDF]

open access: yesEvol Dev
Novel and stressful environments can lead to the expression of previously cryptic genetic variation. Using spadefoot tadpoles, we show that the expression of cryptic genetic variation depends on interacting environmental factors, such as diet and competition, suggesting that it contributes to evolutionary change only under specific environmental ...

Estimating Area of Occupancy From Incomplete Occurrence Records: Reproducible Workflow Illustrated on a Comprehensive Dataset of Georgian Snakes. [PDF]

open access: yesEcol Evol
The workflow is presented that helps to optimize grid‐cell size by breakpoint search and to estimate the area of occupancy (AOO) more precisely, if the occurrence data are incomplete. The model was validated on 13 colubrid snakes found in Georgia. The scripts in R and full statistical workflow are provided in the paper and the Supporting Information ...

Long‐term monitoring of common spadefoot toad activity in a European steppe using barn owl pellets [PDF]

open access: yesJournal of Biological Research - Thessaloniki, 2021
Background One third of the worldwide amphibian species are threatened, therefore, efficient monitoring efforts are needed. Amphibians which adopt a hidden lifestyle, such as the common spadefoot toad, are often missed with standard surveying efforts ...

Hurricane Toads

open access: yesEDIS, 2020
Eastern spadefoots are a common but largely unappreciated species of native toad in Florida. Following torrential rains they emerge from hiding and breed in shallow pools.

The eastern boundary of the geographic range of the Pallas’ spadefoot Pelobates vespertinus (Anura, Amphibia) is limited by overwintering temperatures [PDF]

open access: yesHerpetozoa, 2020
We studied the relationship between the geographic distribution of the Pallas’ spadefoot (Pelobates vespertinus) and the soil temperature regime at the eastern boundary of this species’ range (south-western West Siberia and northwest Kazakhstan).

The effect of habitat and climatic on microsatellite diversity and allele length variation

open access: yesFrontiers in Ecology and Evolution, 2022
Microsatellite loci have been shown to vary according to environment. We studied allelic length variation and diversity in eight microsatellite loci along a sharp climatic and habitat gradient in Israel, using the eastern spadefoot toad (Pelobates ...

Call a spade a spade: taxonomy and distribution of Pelobates, with description of a new Balkan endemic [PDF]

open access: yesZooKeys, 2019
The genomic era contributes to update the taxonomy of many debated terrestrial vertebrates. In an accompanying work, we provided a comprehensive molecular assessment of spadefoot toads (Pelobates) using genomic data.

Assortative mixing in eastern spadefoot (Scaphiopus holbrookii) spatial networks is driven by landscape features

open access: yesEcosphere, 2022
Biotic and abiotic factors drive assortative mixing (preference for or sorting with individuals with similar characteristics) in animal populations on a landscape, with implications for dispersal, population structuring, and other ecological and ...
