Vegetation, bird and soundscape characterization: a case study in Braulio Carrillo National Park, Costa Rica

Biota Colombiana, 2021
We assessed the structural complexity of vegetation, birds and soundscapes in two areas of Braulio Carrillo National Park, Costa Rica, with different road exposure, as baseline information for conservation and management. We measured vegetation structure

Time series methods for the analysis of soundscapes and other cyclical ecological data

Methods in Ecology and Evolution
Biodiversity monitoring has entered an era of ‘big data’, exemplified by a near‐continuous collection of sounds, images, chemical and other signals from organisms in diverse ecosystems.

Impact of acoustic index parameters on soundscape comparisons

Methods in Ecology and Evolution
Unprecedented ecosystem changes have prompted prioritisation of scalable and informative environmental monitoring. Ecoacoustics derives information from passive acoustic monitoring of soundscapes as a proxy to describe ecological processes.

Forest structural heterogeneity positively affects bird richness and acoustic diversity in a temperate, central European forest

Frontiers in Ecology and Evolution
IntroductionForests managed for timber production can also be managed for biodiversity conservation by retaining structures typical of old-growth forests, which provide heterogenous structures for forest-dwelling species, including birds.

Relationship between acoustic indices, length of recordings and processing time: a methodological test

Biota Colombiana, 2021
Ecoacoustic approaches have the potential to provide rapid biodiversity assessments and avoid costly fieldwork. Their use in biodiversity studies for improving management and conservation of natural landscapes has grown considerably in recent years ...

Biophony in a noisy tropical urban forest fragment

Biota Colombiana, 2021
Anthropogenic noise, which is part of an urban soundscape, can negatively affect the behaviour of wild animals. Here we investigated how biophony (animal sounds) was affected by noise in an urban Brazilian forest fragment.

Natural soundscapes as a disciplinary bridge in pursuit of sustainability: research themes and priorities

Ecosystems and People
Natural soundscapes, a blend of natural and human-made sounds, enhance human health by reducing stress, improving cognitive function, and increasing happiness. They foster a connection to nature and raise awareness of biodiversity loss.
