Quantifying the effect of forest edge on tropical fauna using explainable ecoacoustics metrics [PDF]

Tropical forests are biodiversity hotspots but increasingly fragmented by human activities, multiplying forest edges that alter microclimates and species dynamics. While edge effect on plants is well documented, its impact on fauna remains less ex-plored.

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

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.

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.
