Vocalizations of anuran amphibians have received much attention in studies behavioral ecology and physiology, but also provide informative characters for identifying delimiting species. We here review the terminology variation frog calls from a perspective integrative taxonomy, hands-on protocols recording, analyzing, comparing, interpreting describing these sounds. Our focus is on advertisement calls, which serve as premating isolation mechanisms and, therefore, convey important taxonomic...
Species distributed across vast continental areas and major biomes provide unique model systems for studies of biotic diversification, yet also constitute daunting financial, logistic political challenges data collection such regions. The tree frog Dendropsophus minutus (Anura: Hylidae) is a nominal species, continentally in South America, that may represent complex multiple each with more limited distribution. To understand the spatial pattern molecular diversity throughout range this...
Jansen, M., Bloch, R., Schulze, A. & Pfenninger, M. (2011). Integrative inventory of Bolivia’s lowland anurans reveals hidden diversity. — Zoologica Scripta, 40 , 567–583. We conducted an integrative species and re‐evaluated the taxonomic status anuran populations from Bolivia that we putatively ordered to 59 a priori species. The analyses own published data mtDNA (16S), bioacoustics, adult tadpole morphology, however, revealed total number 69 divergent lineages. With at hand, assignment...
Abstract Motivation We generated a novel database of Neotropical snakes (one the world's richest herpetofauna) combining most comprehensive, manually compiled distribution dataset with publicly available data. assess, for first time, diversity patterns all as well sampling density and biases. Main types variables contained three databases species occurrences: downloaded from Global Biodiversity Information Facility (GBIF), verified built through taxonomic work specialized literature,...
Rapid environmental change in highly biodiverse tropical regions demands efficient biomonitoring programmes. While existing metrics of species diversity and community composition rely on encounter-based survey data, eDNA recently emerged as alternative approach. Costs ecological value eDNA-based methods have rarely been evaluated regions, where high richness is accompanied by functional (e.g., the use different microhabitats life stages). We first tested whether estimation frogs' structure...
The last decades have witnessed a rapid increase in our knowledge about amphibian diversity, and growing number of studies focused on anuran larval stages. Tadpoles can provide key information for conservation issues the understanding evolution. Moreover, research tadpoles has potential to advance species delimitation diverse still understudied Neotropical fauna. In this study we present morphological tadpole characterisations 41 lowland illustrated by detailed imagery (mainly live...
Factors driving the spatial configuration of centres endemism have long been a topic broad interest and debate. Due to different eco‐evolutionary processes, these highly biodiverse areas may harbour amounts ancient recently diverged organisms (paleo‐ neo‐endemism, respectively). Patterns still need be measured at distinct phylogenetic levels for most clades and, consequently, little is known about distribution, age causes such patterns. Here we tested presence with high (PE) in diverse...
We developed the WildLIVE platform to enable curation, analysis and mobilization of data from high-throughput biodiversity monitoring for European global cross-domain space pro-grams. The implements “webby” FAIR Digital Objects leveraging on RO-Crate Signposting foster self-contained operation machines contained digital resources (machine actionability).
Genetic data in studies of systematics Amazonian amphibians frequently reveal that purportedly widespread single species reality comprise complexes. This means real richness may be significantly higher than current estimates. Here we combine genetic, morphological, and bioacoustic to assess the phylogenetic relationships boundaries two Dendropsophus leucophyllatus group: D. triangulum. Our results uncovered existence five confirmed four unconfirmed candidate species. Among species, three...
Scinax fuscomarginatus, parkeri, trilineatus, lutzorum, and pusillus are morphologically similar species with controversial taxonomy associated open formations of South America east the Andes. We used external morphology, advertisement call, molecular sequences to assess these species. Phylogenetic analysis data showed a well-supported monophyletic group divided into two main clades several subclades. Specimens Hyla madeirae (synonym S. fuscomarginatus) those from Serra do Cachimbo...
The outstanding species richness of Amazonia has fascinated biologists for centuries. However, the records actual numbers and distribution forming its ecosystems are so incomplete that understanding historical causes regional determinants this diversity remain speculative. Anuran clades have repeatedly been documented to harbour many unnamed in region, notably Boana albopunctata group. Considering ecology group, we hypothesized it diversified via successive trans-riverine dispersals during...
Zoologists have widely acknowledged the utility of classification systems for characterising variation in anuran egg and clutch types, tadpole morphotypes, embryonic development, amplexus types reproductive modes. These facilitated unambiguous communication between researchers, often working completely different fields (e.g. taxonomy, ecology, behaviour), as well comparisons among studies. A syntactic system, classifying call guilds, is so far lacking. Based on examination calls 1253 species...
Character displacement is commonly observed when species occur in secondary contact zones and traits related to resource competition or reproduction diverge sympatry. However, few studies have considered the factors determining delimiting direction of character evolution this context. We studied advertisement calls two hylid frogs from allopatric sympatric populations, both which call with similar frequencies but differ substantially temporal parameters. found asymmetrical sympatry, as only...
Two new species of Pseudopaludicola from midwestern Brazil are described. One them, distributed in Bolivian and Brazilian areas within the Upper Paraguay Guaporé river basins, is characterized by presence a conspicuous conical tubercle on each heel, T-shaped terminal phalanges, so belongs to formally recognized pusilla group. The advertisement call composed series 14–720 notes with concatenated pulses—each lasting for 5–25 ms—and mean dominant frequency 5071 ± 242 Hz. second species,...
The growing public interest in biodiversity monitoring has led to a significant increase initiatives that unite citizen scientists, researchers, and machine learning technologies. In this context, we introduce WildLIVE!, dynamic biomonitoring science project. participants analyze vast array of images from long-term camera trapping project Bolivia investigate the impacts shifting environmental factors on wildlife. From 2020 2023, more than 850 registered for contributing nearly 9,000 hours...
Camera traps and passive acoustic devices are particularly useful in providing non-invasive methods to document wildlife diversity, ecology, behavior, conservation. The application of autonomous Internet Things (IoT) sensors is constantly developing opens up new possibilities for research nature conservation such as taxon identification based on real-time audio processing the field (Höchst et al. 2022). Furthermore, amount associated recorded digital photos, videos, files growing at a rapid...
We describe a new species of Xenopholis from the Chiquitano Region in eastern lowlands Bolivia. The can be identified as member genus by its vertebral morphology. differs other two unique, uniform dorsal color pattern. It further X. scalaris having prefrontals and narrow septum within each neural spine perpendicular to long axis. For we present records Bolivia, including highest altitudinal record for (Serranía Beu Pilón Lajas Reserve, Department La Paz, 1500 m).
During an inventory and ecological study of amphibians in the lowlands Bolivia, we recorded two populations a largerepresentative Leptodactylus pentadactylus species group (sensu Heyer 1979, 2005) formerly assigned to L.labyrinthicus. However, analyses morphology, advertisement call, Bayesian inference mitochondrial DNA (16S)provided evidence for heterospecific status regard L. labyrinthicus. Using integrative taxonomic approach weherein assign these tentatively vastus. This poses range...
Abstract Large carnivores such as the jaguar Panthera onca are particularly susceptible to population decline and local extinction a result of habitat loss. Here we report on long-term monitoring in mixed land-use area eastern lowlands Bolivia from March 2017 December 2019. We recorded 15 individuals four reproduction events (five offspring three females), suggesting that our study harbours resident breeding population. Seven iterations spatially explicit capture–recapture models provided...
