Накратко на български
Тропическите влечуги и земноземни се изследват чрез запис на техните звуци, за да се разбере как климатичните промени влияят върху размножаването им. Това е важно, защото тези животни са силно застрашени и трябва да се оцени рискът от тяхното изчезване.

Eavesdropping on the tropics: assessment of climate change impacts on amphibians through passive acoustic monitoring
Current climate change is a major threat for biodiversity conservation. Global warming has caused shifts in species distributions, the timing of biological processes, and may be involved in regional and major extinctions. Providing original knowledge relevant to predict, mitigate, and perhaps prevent these impacts is a key and urgent challenge for current biology. The effects of climate change are considered to be significantly deleterious in amphibians, which are the most endangered group of vertebrates, with more than 40% of its species classified as threatened. According to emerging hypotheses, tropical amphibians are prone to considerably higher risk of decline by environmental warming than temperate zone amphibians. Therefore, in addition to other threats, climate change is likely exacerbating the vulnerability of amphibian diversity, particularly in the world’s most biologically diverse region. Acoustic communication plays a prominent role in mate choice and reproduction in amphibian anurans, and hence is crucial for individual fitness. However, sound production is strongly influenced by environmental factors and few studies have explored whether recent climate change may compromise the performance of calling activity in amphibians. Animal sounds are generally species-specific and therefore embed a signature of animal diversity. Based on this principle, new acoustic technologies have recently developed to automatically monitor animal populations and communities. These powerful tools provide non-invasive and inexpensive methods expected to facilitate biodiversity assessments at large spatio-temporal scales. Therefore, the overall objectives of the present project are the following: ASSESS the effects of climate change on reproductive behaviour and geographical distribution of amphibian species and communities through a new approach based on the integration of bioacoustics and biogeography DEVELOP, TEST and DISSEMINATE new acoustic techniques for non-invasive biodiversity assessments and the study of animal species and communities CONTRIBUTE to public awareness of the threat of climate change as well as to environmental policies aimed at the mitigation or prevention of its impacts on biodiversity

Цел на проекта
Recent climate change is a major threat for conservation of amphibian diversity, the most endangered group of vertebrates. Species distribution models derived from functional traits have been proposed to provide more robust predictions of future climate-induced shifts in environmental suitability than commonly used correlative models. The proposed project aims, for the first time, to examine species vulnerability to climate change through a novel integration of two scientific disciplines, bioacoustics and biogeography, thanks to the use of new tools in acoustic monitoring, signal processing and species distribution modelling. We will first explore how a key and environment-dependent behavioural trait in amphibian anurans (i.e., reproductive calling behaviour) responds across climatic gradients and subsequently expand these findings into larger temporal and spatial scales through mechanistic approach at two levels of organisation, species and community. The MSCA is proposed as a 3-year GF. One of the most cited research groups in ecology (UFG) will host the fellow during the outgoing phase in Brazil, where data collection, first analyses, and training in biogeography will be conducted. The third year of return to the host organisation in France, with a leading group in bioacoustics and signal processing (MNHN), will be devoted to training in acoustic diversity indices, software development, and most transfer and dissemination activities. The MSCA will enable the fellow to be one of the first researchers with expertise in both bioacoustics and biogeography and hence will open up the best career possibilities for him and new collaboration opportunities for the host organisations. As the first using this novel approach, the MSCA is expected to provide advances in these two disciplines as well as to promote new scientific pathways. A series of outreach activities will also contribute to public education and awareness of amphibian decline and climate change threats.
