WABAD: A world annotated bird acoustic dataset for passive acoustic monitoring. [PDF]

Ecology
Abstract Under the current global biodiversity crisis, there is a need for automated and noninvasive monitoring techniques that can gather large amounts of data cost‐effectively at various ecological scales, from local to large spatial scales. These data can then be analyzed to inform stakeholders and decision‐makers.

Automated detection of frog calls and choruses by pulse repetition rate. [PDF]

Conserv Biol, 2021
Abstract Anurans (frogs and toads) are among the most globally threatened taxonomic groups. Successful conservation of anurans will rely on improved data on the status and changes in local populations, particularly for rare and threatened species.

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 ...

Navigating scale and interdisciplinary dynamics in conservation social science. [PDF]

Conserv Biol
Abstract To better understand and address global human–environment crises, interdisciplinary collaborations across the natural and social sciences have become increasingly common in conservation. Within such collaborations, the question of scale can cause tensions: how to agree on the unit of measurement and analysis?

Insights on the functional composition of specialist and generalist birds throughout continuous and fragmented forests. [PDF]

Ecol Evol, 2019
Specialist birds had lower functional beta diversity in continuous forest than generalist birds. Generalist birds had lower functional beta diversity in forest fragments than specialist birds. Specialists were positively associated with more parameters of fragmentation than generalists.

The uses and implications of avian vocalizations for conservation planning. [PDF]

Conserv Biol, 2021
Abstract There is a growing recognition that animal behavior can affect wildlife conservation, but there have been few direct studies of animal behavior in conservation programs. However, a great deal of existing behavioral research can be applied in the context of conservation. Research on avian vocalizations provides an excellent example.

Deforestation alters species interactions

Natural Sciences, Volume 3, Issue 2, April 2023., 2023
Abstract Interspecific interactions are a major determinant of stability in ecological communities and are known to vary with biotic and abiotic conditions. Deforestation is the primary driver of the ongoing sixth mass extinction, yet its effect on species interactions remains largely unexplored.

Detecting and reducing heterogeneity of error in acoustic classification

Methods in Ecology and Evolution, Volume 13, Issue 11, Page 2559-2571, November 2022., 2022
Abstract Passive acoustic monitoring can be an effective method for monitoring species, allowing the assembly of large audio datasets, removing logistical constraints in data collection and reducing anthropogenic monitoring disturbances. However, the analysis of large acoustic datasets is challenging and fully automated machine learning processes are ...

Opportunistic predation of a colony of Polybia platycephala (Richards) (Hymenoptera, Vespidae) by Labidus praedator (Smith) (Hymenoptera, Formicidae)

Sociobiology, 2016
Social wasps have developed several defense mechanisms, especially against ants. Predator attacks are the main threat to their nests. The strategy adopted by the wasps, when attacked by ants, is to abandon the nest, thus preserving the adult population ...
