Symposia

Island Biogeography (Monday, 8:00-10:15 am)
Organizer: Sandra Nogué

Islands have fascinated scientists since the times of Hooker and Darwin. They are often described as natural laboratories that provide model systems for the testing of biogeographic, ecological, and evolutionary theories. In this symposium, we will present and discuss the latest advances in island Biogeography covering a range of temporal scales and using examples from plants and animals.

The Biogeography of Cities – Biogeographic, ecological and evolutionary patterns and processes in urban areas (Monday, 10:45 am -12:30 pm)
Organizer: Susanne Renner

Some 56% of the world’s population live in cities, and by 2050, with the urban population more than doubling its current size, nearly 7 of 10 people in the world will live in cities (https://www.worldbank.org/en/home). Enhancing our understanding of the biota of cities therefore is crucial for making cities a more nature-inclusive environment. This symposium brings together research on city-dwelling trees, birds, and insects, bracketed by talks on historic, socioeconomic, and cultural drivers.

Network Biogeography: The Present and Future of Terrestrial Food Webs (Tuesday, 8:00 – 10:15 am)
Co-organizers: Laura Pollock (McGill University, Canada) and Núria Galiana Ibáñez (National Museum of Natural Sciences, Madrid, Spain)

Food webs, like other ecological networks, are dynamic in nature, allowing them to shift and re-wire in response to change. Food webs have survived periods of intense climate change, human defaunation, and mass extinctions, but the magnitude and speed at which contemporary climate change is occurring may outpace the ability of ecological networks, and the species that comprise them, to respond. This symposium focuses on how knowledge of past and present food web structure, and of their resilience, may help  to better protect them and perhaps predict their future.

The Ecological Consequences of Ecosystem Engineering Over the Past 600 Million Years (Tuesday, 10:45 am – 12:30 pm)
Co-organizers: S. Kathleen Lyons (University of Nebraska-Lincoln) and Amelia Villaseñor (The University of Arkansas)

The term ‘ecosystem engineers’ refers to organisms that can both create and eliminate niche space for other taxa and are thus a crucial control on local and regional diversity. Modern ecological theory recognizes the importance of ecosystem engineers in maintaining ecosystems and ecosystem services. This symposium extends the concept of ecosystem engineering to deep-time (>500 million years ago) and evolutionary contexts and showcases research from different disciplinary perspectives including ecology, paleoecology, geobiology, and anthropology.
