Interspecific combat in anurans: a case of Hypsiboas faber (Wied-Neuwied, 1821) (Hylidae) and Rhinella pombali (Baldissera-Jr, Caramaschi & Haddad, 2004) (Bufonidae) [PDF]

open access: yesBiotemas, 2010
We report an interspecific combat involving the tree frog Hypsiboas faber and the toad Rhinella pombali in southeastern Brazil. Since the observation occurred after the beginning of the interaction, either one of the species may have started the fight ...

Warming increases activity in the common tropical frog Eleutherodactylus coqui

open access: yesClimate Change Ecology, 2021
Tropical ecosystems are expected to experience climate warming, with predicted increases in drying and heat extremes in the coming years. Understanding how these changes will affect terrestrial vertebrates such as amphibians is limited.

Comparative High-Density Linkage Mapping Reveals Conserved Genome Structure but Variation in Levels of Heterochiasmy and Location of Recombination Cold Spots in the Common Frog

open access: yesG3: Genes, Genomes, Genetics, 2017
By combining 7077 SNPs and 61 microsatellites, we present the first linkage map for some of the early diverged lineages of the common frog, Rana temporaria, and the densest linkage map to date for this species.

The food spectrum analysis of Rana temporaria and Bufo bufo in anthropogenically transformed habitats of the Ukrainian Roztochchia

open access: yesБіологія тварин, 2023
As a result of the research, 109 individuals of two amphibian species: the common frog (Rana temporaria) and the common toad (Bufo bufo) were selected. These two species are the most numerous among other species of amphibians within the studied territory,

Presence of an alien turtle accelerates hatching of common frog (Rana temporaria) tadpoles [PDF]

open access: yesNeoBiota, 2022
The presence of a predator affects prey populations either by direct predation or by modifying various parts of their life history. We investigated whether the hatching time, developmental stage, and body size at hatching of common frog (Rana temporaria)

Periodic words, common subsequences and frogs

open access: yesThe Annals of Applied Probability, 2022
Let $W^{(n)}$ be the $n$-letter word obtained by repeating a fixed word $W$, and let $R_n$ be a random $n$-letter word over the same alphabet. We show several results about the length of the longest common subsequence (LCS) between $W^{(n)}$ and $R_n$; in particular, we show that its expectation is $γ_W n-O(\sqrt{n})$ for an efficiently-computable ...

Trophic ecology and microhabitat utilization by the Bufo gargarizans, Rana guentheri, and Rana limnocharis in southwestern China

open access: yesZoologia (Curitiba), 2012
We studied the trophic ecology and microhabitat use of the Asiatic toad, Bufo gargarizans Cantor, 1842; Guentheri frog, Rana guentheri (Boulenger, 1882); and the Ricefield frog, Rana limnocharis (Boie, 1834).
