Abstract Research on urban noises affecting acoustic communication of animals is a growing area study and conservation concern. However, the consequences aircraft noise anuran have been explored restricted basis to date. In this study, we investigated impact overflights individual chorus performance signalling in Pedregal frog ( Eleutherodactylus grandis ), microendemic threatened species from Mexico City. During summer 2021, recorded signals male individuals conducted monitoring analyse how social interactions change due overflights. For purpose, evaluated properties call, including call duration, dominant frequency, amplitude, repetition rate. Additionally, measured amplitude environmental by means two types complementary methodological approaches. Our results show changes with longer lower higher overflights, while rate did not vary. Furthermore, decrease number calls within was observed during overflight. Overall, these that causes plastic between conspecifics decrease, thus adding new disturbance already suffers other anthropogenic noises, habitat fragmentation.

Influence of conspecifics and road noise on the properties of the advertisement call of Phyllodytes luteolus (Anura, Hylidae)

Abstract Acoustic communication in animals can be affected by multiple biotic (intra and interspecific) abiotic (e.g., wind rain) natural noises. In addition, human beings produce additional novel sources of noise, which reduce or inhibit the reception acoustic signals conspecifics, leading to behavioral changes. this study, we investigated whether sound conspecifics road noise additively affect parameters advertisement call males a Yellow Heart‐tongued Frog ( Phyllodytes luteolus ). We hypothesized that vocalize choruses (males calling nearby) areas close highways (anthropic noise) will increase their temporal spectral parameters, respectively, avoid signal masking. recorded vocalizations 38 environments N = 18) distant 20) from different social contexts (many few individuals nearby). Contrary our expectation, results indicated had lower dominant frequency calls than those (far highways), density chorus no influence on parameters. Furthermore, found positive relationship between body size intensity, indicating larger emit reach greater distances. The has high frequency, with little overlap anthropic noises (roads), may explain its presence reproductive success species bromeliads urbanized areas.

This research aims at teaching solfeggio and ear training in college music proposes a method for note recognition that combines the musical instrument digital interface (MIDI) hidden Markov models (HMM). The experiment showcases after preprocessing frequency sample signal using HMM model, it achieves target accuracy 20 times of training. From transition probability matrix diagram estimated from all data sets, can be seen is close to diagonal matrix. indicates its high transfer efficiency. study compares model with other two algorithms, results show rate about 99.56%. insertion errors elimination 0.52% 2.58%. superior algorithms. In summary, proposed has extremely strong performance feature universities provide better methods.

Anthropogenic sounds induce escape behaviour in southern stingrays Hypanus americanus

Marine Ecology Progress Series, Год журнала: 2022, Номер 694, С. 125 - 132

Elasmobranchs are an important component of the marine ecosystem that face obvious anthropogenic threats through habitat degradation and overfishing, but impact sounds on these animals is less remains unclear. Using a Y-maze behavioural set-up with sound presentation one side pen, we exposed southern stingrays Hypanus americanus to 4 types sounds: 2-stroke boat, 4-stroke cruise ship airplane. While did not have preference, they exhibit increase in escape behaviours during all treatments. To our knowledge, this first study examine impacts airplane any aquatic animal, found exhibited responses most often sounds. We demonstrate affect response further state more efforts needed determining or physiological elasmobranchs.

Anuran communities increase aggregations of conspecific calls in response to aircraft noise

Current Zoology, Год журнала: 2024, Номер 71(2), С. 223 - 232

Опубликована: Авг. 16, 2024

Abstract Noise pollution has been shown to affect wild animals in various ways, but little is known about its consequences at the community level. Investigating animals’ overall vocal responses noise across multiple sympatric species can reveal complex nature of impacts challenging. In this study, we employed social network analysis (SNA) evaluate how anuran communities and populations vary their calling behaviors response aircraft noise. SNA revealed that conspecific individuals increase aggregation spectral (i.e., minimum frequency, maximum dominant frequency), temporal (call duration, call rate, effort), spectral–temporal features as an airplane passes through. also anurans could interindividual similarity characteristics Furthermore, our traits effect whose behavior did not change previous separate analyses each single traits. This study suggests may pattern combined acoustic properties Our findings highlight importance integrated methods theories for understanding ecological future studies.
