Sympatric song variant in mountain chickadees Poecile gambeli does not reduce aggression from black-capped chickadees Poecile atricapillus [PDF]

, 2016
When habitats overlap and species compete for resources, negative interactions frequently occur. Character displacement in the form of behavioural, social or morphological divergences between closely related species can act to reduce negative ...

The katydid country: bioacoustics and ecology of tettigoniid communities from the Indian subcontinent

Bioacoustics, 2022
The study provides the first description of acoustic communities from a subtropical rainforest in Northeast India and a previously unexplored site from the Western Ghats. We describe call structures of 15 katydid species from the Indian subcontinent. The

Automated bioacoustic identification of species [PDF]

Anais da Academia Brasileira de Ciências, 2004
Research into the automated identification of animals by bioacoustics is becoming more widespread mainly due to difficulties in carrying out manual surveys. This paper describes automated recognition of insects (Orthoptera) using time domain signal coding and artificial neural networks.

Global birdsong embeddings enable superior transfer learning for bioacoustic classification

Scientific Reports, 2023
Automated bioacoustic analysis aids understanding and protection of both marine and terrestrial animals and their habitats across extensive spatiotemporal scales, and typically involves analyzing vast collections of acoustic data. With the advent of deep

Sea Lice Are Sensitive to Low Frequency Sounds

Journal of Marine Science and Engineering, 2021
The salmon louse Lepeophtheirus salmonis is a major disease problem in salmonids farming and there are indications that it also plays a role in the decline of wild salmon stocks.

Management of acoustic metadata for bioacoustics

Ecological Informatics, 2016
AbstractRecent expansion in the capabilities of passive acoustic monitoring of sound-producing animals is providing expansive data sets in many locations. These long-term data sets will allow the investigation of questions related to the ecology of sound-producing animals on time scales ranging from diel and seasonal to inter-annual and decadal ...

Sound categorization by crocodilians

iScience, 2023
Summary: Rapidly sorting the information contained in a stream of stimuli is a major challenge for animals. One cognitive mechanism for achieving this goal is categorization, where the receiving individual considers a continuous variation of a stimulus ...

Assessing spatial variability and efficacy of surrogate species at an ecosystem scale. [PDF]

Conserv Biol
Abstract Preserving biodiversity is a central goal of conservation, but, in practice, monitoring biodiversity often involves assessing population trends for one or a handful of species that are presumed proxies for biodiversity. Despite the popularity of surrogate species strategies, the links between biodiversity and surrogate species are rarely ...
