Current Analogues of Future Climate Indicate the Likely Response of a Sensitive Montane Tropical Avifauna to a Warming World
Climate change represents the most significant threat to tropical flora and fauna in the mountains of Australia. Alexander Anderson, our lecturer, mention there is an urgent need to project gradients and thermal tolerances that make tropical ecosystems vulnerable. For instance, species distribution modeling can be used to predict possible impacts of climate change on biodiversity. He discussed that over past years climate change has been associated with many modifications in distributions and abundances species. The study he presented us was performed by analyzing the density of rainforest through gradients of the north east part of Australia regarding temperature. This was accomplished in order to assess the absence of historical data, shift detections and possible growth or decay of bird species. Results showed a habitat shift of species ranged from endemic, insectivorous and furgivores. It was really interesting to see how some future projection of populations decline while others increase because of temperature changes. After the discussion, results offer an opportunity to test responses of bird species regarding the climate change.
