Zootecnia di precisione, la bioacustica identifica in porcilaia la posizione degli animali malati [PDF]

, 2006
Un nuovo strumento di zootecnia di precisione per monitorare lo stato di salute degli animali in tempo reale è la bioacustica. L’analisi del suono è stata impiegata per localizzare animali affetti da tosse in un contesto di campo. È possibile identificare l’esatta posizione della fonte sonora utilizzando la differenza di tempo di ricezione, di un ...

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 ...

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.

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?

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 ...

Torrent frogs have fewer macroparasites but higher rates of chytrid infection in landscapes with smaller forest cover

Ecosphere, Volume 11, Issue 6, June 2020., 2020
Abstract Deforestation can compromise ecological processes and biotic interactions, including the host–parasite relationship. While some parasites infect only one host, others require multiple hosts to complete their complex life cycles. In this context, different parasites may have different demands and traits and may have specific responses to ...
