The brown tree frog (Litoria ewingii) is a relatively widespread, commonly encountered pelodryadid from south-eastern Australia, known for its characteristic whistling call. distribution of Litoria ewingii spans over more than 350,000 km2, encompassing range moist temperate habitats, and fragmented by well-known biogeographic barriers. A preliminary analysis mitochondrial DNA sequences revealed evidence deep phylogenetic structure between some these populations. In this study, we sought to re-evaluate the systematics taxonomy sensu lato analysing variation in nuclear DNA, adult morphology male advertisement calls throughout species range.

Systematic evaluation of molecular genetic, morphological and acoustic variation reveals three species in the Litoria revelata complex (Anura: Pelodryadidae)

Zootaxa, Journal Year: 2025, Volume and Issue: 5584(3), P. 301 - 338

We used a combination of nuclear and mitochondrial genetic data, body measurements colouration, male advertisement calls to analyse the systematic implications variation in whirring treefrog Litoria revelata complex, which occurs three allopatric populations—north-eastern New South Wales/south-eastern Queensland, mid-eastern northern Queensland. The populations each form divergent lineages for both (single nucleotide polymorphisms; SNP) datasets are diagnosable also on basis morphology calls. In combination, we use these lines data recognise species: L. north-eastern eungellensis sp. nov. resurrected corbeni provide preliminary conservation assessment species, with latter two species being localised very small upland areas warranting listing attention.

The iNaturalist platform as a source of data to study amphibians in Brazil

Anais da Academia Brasileira de Ciências, Journal Year: 2023, Volume and Issue: 95(1)

Published: Jan. 1, 2023

Based on debilitating recent budget cuts for science, Brazilian researchers had to find alternative ways continue scientific production. Here we provide a perspective the use of citizen-science data deposited in iNaturalist platform as an source support biodiversity research. Observations contributed by volunteers can be analyzed at large spatial and temporal scales respond questions behavioral population ecology. We this potential through example amphibians, group that is less studied worldwide than birds. In fact, our knowledge, only two studies have been published are based amphibians. At time writing, has over 14,800 research grade observations from Brazil, representing 698 species, number increasing daily. Compared other species-rich countries, volunteer-collected datasets Brazil cover relatively high taxonomic diversity (61%), providing plethora valuable data. Despite potential, there gaps sampling Brazil. encourage established budding herpetologists not retrieve data, but also contribute actively, with new observations, well identifying species existing records.

Anuran accents: Continental‐scale citizen science data reveal spatial and temporal patterns of call variability

Ecology and Evolution, Journal Year: 2020, Volume and Issue: 10(21), P. 12115 - 12128

Published: Oct. 6, 2020

Abstract Many animals rely on vocal communication for mating advertisement, territorial displays, and warning calls. Advertisement calls are species‐specific, serve as a premating isolation mechanism, reinforce species boundaries. Nevertheless, there is great deal of interspecific variability advertisement Quantifying the among individuals within across critical to understand call evolution boundaries, may build foundation further research in animal communication. However, collecting large volume recordings geographic area has traditionally posed logistical barrier. We used data from continental‐scale citizen science project FrogID investigate spatial temporal patterns characteristics six Australian frog species. found intraspecific both duration peak frequency Using resampling methods, we show that was related number recorded, encompassed by those individuals, intra‐annual time difference between recordings. conclude order accurately variation, or “anuran accents,” sample must be numerous ( N ≥ 20), encompass relative species' range, collected throughout calling season.

Anthropogenic habitat modification alters calling phenology of frogs

Anthropogenic habitat modification significantly challenges biodiversity. With its intensification, understanding species' capacity to adapt is critical for conservation planning. However, little known about whether and how different species are responding, particularly among frogs. We used a continental-scale citizen science dataset of >226,000 audio recordings 42 Australian frog investigate calling-a proxy breeding-phenology varied along an anthropogenic gradient. Calling started earlier breeding seasons lengthened with increasing intensity. Breeding averaged 22.9 ± 8.25 days (standard error) longer in the most modified compared least regions, suggesting that activity was sensitive modification. also examined calls gradient by analysing temporal spectral properties advertisement from subset 441 three broadly distributed species. There no appreciable effect on any measured call variables, although there high variability. continued modification, may shift towards seasons, largely unknown ecological consequences terms proximate ultimate fitness.

Assessment of the acoustic adaptation hypothesis in frogs using large‐scale citizen science data

Journal of Zoology, Journal Year: 2023, Volume and Issue: 320(4), P. 271 - 281

Published: June 6, 2023

Abstract Acoustic communication is vital to the survival and fitness of many vertebrates. While successful reliant on acoustic signals reaching an intended receiver maintaining content fidelity, propagating are attenuated by environmental factors such as habitat type. The adaptation hypothesis (AAH) predicts that properties selected for optimal transmission in habitats which they propagate. To date, consistent evidence support theory lacking, but studies have typically been primarily based localized datasets with small sample sizes. Citizen science emerging a potential means overcome challenges associated broad‐scale sampling, allowing us assess validity AAH frogs continental scale. We analysed male advertisement calls 674 individual banjo ( Limnodynastes dorsalis , L. dumerilii interioris terraereginae ) from across their range, pairing these citizen data remotely sensed measures complexity. we detected considerable variation structure within among frog species, this was not strongly correlated Thus, found no AAH. However, our study spanning area over 1.7 million km 2 conducted largest‐scale test contributing global understanding signal evolution.
