Данные проекта

Human induced rapid environmental changes (HIREC) are drastic and widespread, often putting organisms into evolutionary novel situations. Although most species do not tolerate well these environmental changes, a few not only do well but may also become dominant and widespread. Such a dynamic in species turnover and changes in species richness may reduce biotic distinctness. This phenomenon known as biotic homogenization is important because could erode ecosystem services with significant consequences for ecological and human wellbeing. Two forms of HIREC appear central and mutually reinforcing biotic homogenization: the habitat loss associated with urbanization and the introduction of non-indigenous species by human activities. Despite taxonomic homogenization has been widely reported, the underlying mechanisms remain controversial. Besides, mounting evidences shows that species diversity influences ecosystem functions, however what determines the magnitude of its effects is species identity with their phylogenetic characteristics, which are often overlooked. In this project, we investigate whether and how the urbanization process favors taxonomic, and phylogenetic homogenization in birds due to the interplay between loss of native species (little tolerant to urbanization process) and additions of non-indigenous species by human-assisted introductions. In a scenario of increasing globalization, where most of human populations live in cities and invasive species are increasingly introduced, understanding the processes that drive biotic homogenization is crucial to develop informed strategies of adaptation to an human dominated world. Altogether, the results of this proposal are critical premises to forecast future evolutionary trajectories of an urbanizing planet.

Методы сбора

we perform bird counts and behavioural observations across different environments that vary in urban development. We use a standardised point count method during the early morning counting all individuals from all species observed in a 5 minutes period. To deal with pseudoreplication and spatial autocorrelation we considered a minimum distance between point counts of 250 meters, trying to maximize the number of points and recording the spatial coordinates to be incorporated in statistical analyses. Each site was sampled twice a year during the breeding season (first sample: October-November, and second sample: January– February) for two years (i.e. two breeding seasons), to incorporate both seasonal and year-to-year variation in species composition.
