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

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

Studies of social wasp diversity in Brazil: Over 30 years of research, advancements and priorities
The first records of social wasps in Brazil were made during expeditions that focused on the taxonomy and distribution of the species in the country. From the 70s there was a change in the essence of publications on the diversity of social wasps, which ...
