Накратко на български

Пасивният акустичен мониторинг следи как се променят групи от видове в планините, например от ниските гори до високите ливади. Това помага да се разбере как животните реагират на климатичните промени и екстремните условия в реално време.

Listening to change: acoustic monitoring of multi-trophic community dynamics in the face of increasingly variable and extreme environmental conditions

Species are often predicted to lag behind the unprecedented pace of ecological changes imposed by current human activities. Such changes result not only in modification of the mean environmental values in an ecosystem but also in increasingly extreme and variable environmental conditions. These extreme and variable conditions operate at fine spatio-temporal scales. Passive Acoustic Monitoring (PAM) is a rapidly growing field of research that allows for an unparalleled temporal resolution and a wide taxonomic diversity of sound producing species in terrestrial and aquatic environments. In this context, I will use PAM to understand fine scale spatio-temporal community dynamics in response to climate change. For that I plan to study elevational gradients along mountain ranges. This will allow to cover a variety of environmental conditions along different elevations from low altitude forests to high altitude meadows. Moreover moutain environments are warming up twice as fast as the rest of the earth so they are under particularly strong constraints. With this research, I aim to understand community dynamics at unprecedented spatio-temporal resolution.

Цел на проекта

Species are often predicted to lag behind the unprecedented pace of ecological changes imposed by current human activities. Such changes result not only in modification of the mean environmental values in an ecosystem but also in increasingly extreme and variable environmental conditions. These extreme and variable conditions operate at fine spatio-temporal scales. A mechanistic understanding of these dynamics in response to new environmental conditions thus requires monitoring, analysing and modelling at such fine spatio-temporal resolution. Passive acoustic monitoring (PAM) is a rapidly growing field of research that allows for an unparalleled temporal resolution and a wide taxonomic diversity of sound producing species in terrestrial and aquatic environments. In this context, I will use PAM to understand fine scale spatio-temporal community dynamics in response to increasingly extreme and variable environmental conditions. For that I plan to develop a methodological and conceptual framework to understand community dynamics at unprecedented spatio-temporal resolution. First, I will use unsupervised learning to characterise acoustic community composition, creating acoustic groups that I will ecologically identify. I will then use these groups to assess spatio-temporal variation of community composition in these environments and their associations using network models. Finally, I will use different change scenarios to investigate the potential impact of these changes on community dynamics. This research will increase our understanding of the importance of extreme and variable environmental conditions in driving community dynamics.
