Amphibian populations fluctuate naturally in size and range and large datasets are required to establish trends in species dynamics. To determine population trends for the endangered Suweon Treefrog (Dryophytes suweonensis), we conducted aural surveys in 2015, 2016, and 2017 at each of 122 sites where the species was known to occur in the Republic of Korea. Despite being based on individual counts, the focus of this study was to establish population trends rather than population size estimates…

Korean endemic species no more: on the occurrence of Pelophylax chosenicus in China
Understanding species distribution is the first requirement to work on their behaviour, conservation, and phylogeography. Over the last decades, the number of species described on the Korean

Defining Conservation Requirements for the Suweon Treefrog (Dryophytes suweonensis) Using Species Distribution Models
Numerous amphibian species are declining because of habitat loss and fragmentation due to urbanization of landscapes and the construction of roads. This is a mounting threat to species restricted to
A new method for the estimation of minimum adult frog density from a large-scale audial survey
This study suggests that lek-breeders would be more suitable than explosive-breeding taxa for minimum population size estimates from audial data, and demonstrates a method for obtaining minimum adult population sizes from vocalising anuran counts by using sex ratios, life history and vocalising behaviour parameters from other studies.
Update on Distribution and Conservation Status of Amphibians in the Democratic People’s Republic of Korea: Conclusions Based on Field Surveys, Environmental Modelling, Molecular Analyses and Call Properties
It is argued that species relying on agricultural wetlands such as rice paddies are not under imminent threat due to the enduring presence of extensive agricultural landscapes with low rates of chemical use and mechanisation.
Driven to the edge: Species distribution modeling of a Clawed Salamander (Hynobiidae: Onychodactylus koreanus) predicts range shifts and drastic decrease of suitable habitats in response to climate change
The current habitat suitability model generated using the maximum entropy algorithm was highly consistent with the known distribution of the species and had good predictive performance, and further ecological studies and population monitoring should be conducted across the range of O. koreanus.
Interspecific Variation in Seasonal Migration and Brumation Behavior in Two Closely Related Species of Treefrogs
Differences in seasonal migration and hibernation habitats between Dryophytes suweonensis and D. japonicus are demonstrated and highlight different ecological requirements between the two species, which may result from their segregated evolutionary histories.
Yellow sea mediated segregation between North East Asian Dryophytes species
While comparatively few amphibian species have been described on the North East Asian mainland in the last decades, several species have been the subject of taxonomical debates in relation to the
Large-Scale Hybridisation as an Extinction Threat to the Suweon Treefrog (Hylidae: Dryophytes suweonensis)
A generalised, bi-directional, and geographically widespread hybridisation is revealed between the spatially restricted D. suweonensis and the widespread D. japonicus.


Description of a seminatural habitat of the endangered Suweon treefrog Hyla suweonensis
The habitat characteristics of a seminatural site for H. suweonensis, a treefrog species endemic to Korea, have a large percentage of rice paddies with a very low percentage of urban areas, a feature consistent with findings of a previous study.
Introduced bullfrogs are associated with increased Batrachochytrium dendrobatidis prevalence and reduced occurrence of Korean treefrogs
The presence of L. catesbeianus can now be added to the list of factors responsible for the decline of D. suweonensis populations, and the endangered Dryophytes suwe onensis displays a significantly higher Bd prevalence than the more abundant D. japonicus.
Estimating population size in the European tree frog (Hyla arborea) using individual recognition and chorus counts
It is shown that there is no simple relationship between maximum or mean chorus size and modelled male population sizes estimated from CMR study and that population trends inferred from chorus counts are likely to be biased to an unknown extent.
Annual Surveys of Larval Ambystoma cingulatum Reveal Large Differences in Dates of Pond Residency
This analysis suggested that the primary dates of hatching occurred in late February 2005 and early January 2006, a difference that corresponds to that seen in the residency of the latest larval stages.
Surveys of Calling Amphibians in North Dakota
Amphibians have received increased attention in recent years from the scientific community and general public alike. Many populations throughout the world have declined or have been extirpated, often
Abiotic effects on calling phenology of three frog species in Korea
Studying the seasonal and diel calling activities of anuran species in a wetland in central Korea to determine the calling season and to evaluate the effects of abiotic factors on male calling determined R. nigromaculata to be a summer caller independent of weather.
There is a general paucity of information about natural amphibian populations under normal conditions and this information is needed to understand why declines in population number occur.
Environmental factors influencing calling in sympatric anurans
This work examines the relationship between multiple abiotic environmental variables – specifically, air and water temperature, rainfall, barometric pressure, relative humidity and wind velocity – and the calling activity of five species in an anuran community in New Brunswick, Canada and found that each species responded to a unique combination of meteorological variables.
Variations in boldness, behavioural and physiological traits of an endangered and a common hylid species from Korea
The correlation between the endangered D. suweonensis with a narrow ranges and depressed boldness, in comparison to the widespread and closely related D. japonicus is highlighted, making the later species more fit to its environment, allowing for faster escape and wider dispersal capabilities.
