Acoustic indices are not useful for biodiversity research

Methods in Ecology and Evolution
Biodiversity assessment using passive acoustic monitoring has historically been challenging due to the limited availability of multi‐species acoustic detectors.

Listening to the City: Evaluating BirdNET Reliability and Bias in Urban Bird Community Assessments

Remote Sensing in Ecology and Conservation, EarlyView.
BirdNET substantially overestimates urban bird species richness, but seasonal filtering and local calibration meaningfully improve classification precision. ABSTRACT BirdNET is increasingly used for passive acoustic monitoring (PAM), yet its reliability in urban environments that have high levels of anthropogenic noise remains poorly understood.

Threat level and sound production mode modulate acoustic warnings and defensive biting in snakes

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Accurately assessing predation risk is important because it enables prey to match their defensive behaviours to the level of threat and avoid unnecessary investment in costly responses.

Efficient Masked Autoencoder for Birdsong Representation with Applications on Wild Bird Species Classification

Integrative Zoology, EarlyView.
Research on mosquito feeding preferences and the malaria parasites they transmit is essential for understanding the interactions between hosts, vectors, and parasites. In this study, vertebrate hosts were identified in 72 mosquitoes. Most blood meals (58.7%) came from birds, representing 25 species, while 40.0% came from mammals (13 species), and 1.3 ...

Amazonian manatee critical habitat revealed by artificial intelligence‐based passive acoustic techniques

Remote Sensing in Ecology and Conservation
For many species at risk, monitoring challenges related to low visual detectability and elusive behavior limit the use of traditional visual surveys to collect critical information, hindering the development of sound conservation strategies.

The Climate Niche Pressure on the Yunnan–Guizhou Plateau Predominates the Diversification of Advertisement Calls in Frogs (Leptobrachella)

Integrative Zoology, EarlyView.
The diversification of advertisement calls is largely driven by climatic niche differentiation. Our results provide acoustic evidence for studies on ecological speciation in anurans.

Implications of target signal choice in passive acoustic monitoring: an example of age‐ and sex‐dependent vocal repertoire use in African forest elephants (Loxodonta cyclotis)

Remote Sensing in Ecology and Conservation
Passive acoustic monitoring (PAM) is an effective remote sensing approach for sampling acoustically active animal species and is particularly useful for elusive, visually cryptic species inhabiting remote or inaccessible habitats.

The Effects of Noise on the Juvenile Life Stage of Crustaceans: Behavioral, Cellular, and Molecular Responses in Procambarus clarkii

Integrative Zoology, EarlyView.
Juvenile Procambarus clarkii exposed to noise exhibited behavioral changes, shifts in enzymatic activity, and altered expression of stress and immune genes. The findings highlight the sensitivity of invertebrate juveniles to anthropogenic acoustic pollution.

Post‐Release Survival and Behavioral Recovery of a Rehabilitated Short‐Finned Pilot Whale (Globicephala macrorhynchus) in the South China Sea Revealed Through Satellite Tracking

Ecology and Evolution
Post‐release monitoring is critical for evaluating the success of rehabilitating stranded cetaceans, yet such data are scarce for many species in the South China Sea (SCS).

BirdNET: Automated Detection for Monitoring Critically Endangered Lemurs from the Maromizaha Forest

Integrative Zoology, EarlyView.
In this study, we evaluated the effectiveness of integrating PAM with BirdNET, a convolutional neural network originally developed for avian vocalization detection, to monitor two critically endangered lemurs, Indri indri and Varecia variegata, in Madagascar's Maromizaha rainforest.
