Identification key for anuran amphibians in a protected area in the northeastern Atlantic Forest

open access: yesPapéis Avulsos de Zoologia, 2021
The identification of anuran amphibians is still a challenge in megadiverse assemblages. In the Neotropics, the Atlantic Forest harbors more than 600 anuran species, and many studies in this ecoregion report anuran assemblages surpassing 30 species ...

From Gondwana to the Yellow Sea, evolutionary diversifications of true toads Bufo sp. in the Eastern Palearctic and a revisit of species boundaries for Asian lineages

open access: yeseLife, 2022
Taxa with vast distribution ranges often display unresolved phylogeographic structures and unclear taxonomic boundaries resulting in hidden diversity.

Delineating the anuran axial skeleton

open access: yesThe International Journal of Developmental Biology, 2021
The axial skeleton of the anurans has undergone an evolutionary reduction of its bone elements. This structural plan is strongly preserved throughout the order and would have emerged as a highly specialized anatomical adaptation to its locomotor jumping pattern.

CHORUSING PATTERNS OF A DIVERSE ANURAN COMMUNITY, WITH AN EMPHASIS ON SOUTHERN CRAWFISH FROGS (LITHOBATES AREOLATUS AREOLATUS) [PDF]

open access: yes, 2016
Wildlife surveys have a critical role in conservation efforts and the collection of life history data. For anuran amphibians these surveys often focus on calling males.

Watson-Crick conjugates of words and languages [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
In this work, we explore the concept of Watson-Crick conjugates, also known as $θ$-conjugates (where $θ$ is an antimorphic involution), of words and languages.

CALL BROADCASTING AND AUTOMATED RECORDERS AS TOOLS FOR ANURAN SURVEYS IN A SUBARCTIC TUNDRA LANDSCAPE [PDF]

open access: yes, 2014
Relatively little is known about population ecology of anurans in arctic and subarctic tundra regions, in part because it is difficult to survey anurans in these landscapes.

USING CALLING ACTIVITY TO PREDICT CALLING ACTIVITY: A CASE STUDY WITH THE ENDANGERED HOUSTON TOAD (BUFO [ANAXYRUS] HOUSTONENSIS) [PDF]

open access: yes, 2015
Understanding anuran calling activity patterns is important for maximizing efficiency and value of call survey data collection and analyses. Previous studies have primarily focused on identifying and quantifying abiotic variables that influence anuran ...

Broadcasting on Random Directed Acyclic Graphs

open access: yes, 2020
We study a generalization of the well-known model of broadcasting on trees. Consider a directed acyclic graph (DAG) with a unique source vertex $X$, and suppose all other vertices have indegree $d\geq 2$.

Development and characterization of novel microsatellite loci in the native tree frog species, Polypedates braueri and cross-species amplification in the alien species, P. megacephalus, in Taiwan [PDF]

open access: yesBiodiversity Data Journal
Polypedates megacephalus is an alien species first recorded in 2006 in Taiwan. The expanding population of P. megacephalus poses potential threats to the native frog species, especially to the closely-related species P. braueri.

Frog origins: inferences based on ancestral reconstructions of locomotor performance and anatomy [PDF]

open access: yes, 2016
Frogs are the most species-rich and ecologically diverse group of amphibians and are characterized by a unique body plan including long legs, elongated ilia, and fused caudal vertebrae.
