Among different approaches to exploring and describing the ecological complexity of natural environments, soundscape analyses have recently provided useful proxies for understanding interpreting dynamic patterns processes in a landscape. Nevertheless, study soundscapes remains new field with no internationally accepted protocols. This work provides first guidelines monitoring three tropical areas, specifically located Atlantic Forest, Rupestrian fields, Cerrado (Brazil). Each area was...
Abstract Consistent and well‐defined criteria for the classification measurement of humpback whale song features are essential robust comparisons between investigators. Song structure terminology has been well‐established used by many authors, though at times inconsistently. This review discusses development nomenclature describing explores potential significance often‐overlooked variation in patterns. Within hierarchical definition song, most problematic issues arise from inconsistent...
Until recently, freshwater turtles were thought to be silent reptiles, neither vocalizing nor hearing very well. We recorded individuals in nature, captivity, and during interactions between adults hatchlings show that adult turtles, Podocnemis expansa, produce sounds out of the water. Sounds emitted by inside egg, open nests, river, captive conditions. Adult females producing while basking, nesting, captivity. Females river approaching responding hatchling sounds. detected 2,122 sounds,...
The application of acoustic indices is incipient and still needs validation before it can reliably characterize soundscapes monitor rapidly disappearing hot-spot areas as the Brazilian tropical savanna (Cerrado). Here we investigate which six better correlate with 24 h zoophony richness insects, anurans, birds, mammals. We sampled one minute every 30 minutes for seven days on three sites in Serra da Canastra National Park (Minas Gerais state, Brazil) extracted sonotype based recordings a...
The social behavior of turtles during the nesting season can be attributed to a series functions such as reducing predation, increasing hatchling survivorship, and information exchange between females. However, mechanism(s) used remain in group different phases has yet explained. objective this study is document sounds produced by Giant South American River Turtle, Podocnemis expansa, period, identify how acoustic mechanisms might facilitate aggregation period. From September 2009 October...
Acoustic communication is a way of information exchange between individuals, and it used by several animal species. Therefore, the detection, recognition correct understanding acoustic signals are key factors in effective communication. The priority effectiveness rather than perfection, being avoids affecting sound-based system One that can affect overlap time frequency during signal transmission, known as masking. type sound cause masking anthropogenic noise, which currently increasing due...
An eight year summary of opportunistic sightings small cetaceans in Abrolhos Bank, eastern Brazil, is provided with reference to species distribution, habitat use and group size. Data were gathered from 1997 2004 during research cruises (more than 500 days sampling effort) aiming study the biology humpback whales, analyzed using a geographic information system (GIS). Dolphin identified on 151 sightings: estuarine dolphin, Sotalia guianensis – 49%; roughtoothed Steno bredanensis 16%;...
There are only a few studies documenting acoustic communication in chelonians; here we provide additional evidence that sound plays an important role the interchange of information this group. We recorded 12 nests Dermochelys coriacea during March 2012 at Barra de la Cruz Beach, Oaxaca, Mexico. Four types sounds were identified from recordings after 51 d incubation; our results reinforce idea to coordinate group behavior turtles.
Advances in technologies for data acquisition, storage and analysis have boosted Acoustic Ecology studies, but protocols are still lacking. There is a need of more research to understand which methodologies can be applied answer ecological questions different environments with varying temporal spatial dynamics. Tropical forests generally complex than temperate ones, both terms use acoustic space species diversity. The seasonally dry tropical forest (SDTF) Brazil, known as Caatinga,...
Recordings were made in nests of Eretmochelys imbricata and 107 samples 10-min recordings revealed 575 sounds that classified manually into 4 categories. Our results show hawksbill turtles vocalize within the nest, especially during after eclosion, which suggests vocalizations are important for communication among hatchlings to synchronize emergence from nest.
<title>Abstract</title> Under the current global biodiversity crisis, there is a need for automated and non-invasive monitoring techniques that are able to gather large amounts of information cost-effectively at scales. One such technique passive acoustic monitoring, which commonly coupled with automatic identification animal species based on their sound. Automated sound analyses usually require training detection algorithms. These algorithms annotated datasets mark occurrence sounds...
The "Sphyrna Odyssey 2019-2020" mission combined passive acoustic monitoring and environmental DNA (eDNA) to monitor marine mammals in the Mediterranean, focusing on areas impacted by heavy traffic. Sphyrna autonomous vessels, equipped with hydrophones, provided real-time detection of vocalizing species [1], while eDNA sampling from surface waters captured genetic traces over larger spatial areas, including busy shipping lanes [4]. Acoustic data species, detected even absence vocalizations,...
<title>Abstract</title> BirdNET is a popular machine learning tool for automated recognition of bird sounds. Here we evaluate how settings affect the model performance both at vocalization and species levels, using 4,225 one-minute recordings from 67 recording locations worldwide. Giving equal importance to recall precision, low confidence score threshold (0.1-0.3) appears optimal detecting vocalisations, whereas higher thresholds (around 0.5) are more suitable characterising communities....
