EV-1.
Migration
in a changing world
Monday,
August 8,
7:15 PM - 10 PM, Meeting Rooms 513a-b, Level 5, Palais
des congrès de Montréal
Organizers:
Christopher Caudill, Christopher Peery
Description:
A
large number of species undertake one or more migrations among habitat types
during their life cycle. These migrations occur in marine, aquatic, and
terrestrial taxa, and include a large number of species of ecological, economic,
or conservation importance. However, human activities are altering habitats and
migration corridors at multiple scales. Consequently, a mechanistic
understanding of migration behavior and ecology is critical to identifying
important human drivers that negatively affect migratory species, and management
strategies that may minimize or reverse those impacts. After presenting a series
of case studies in a common conceptual context, we will have a roundtable
discussion that addresses synthetic questions such as: (1)
Do some migration events generally have greater effects on ? than others (e.g.,
subadult vs. prebreeding)? (2) Is migration performance affected to a greater
extent by direct human alterations of the migration environment or by indirect
effects influencing phenotypic traits at the outset of migration, such as
alterations to prestaging habitat? (3) Are the major alterations to migration
corridors local (e.g., dams) or regional (e.g., altered climate and thermal
regime) in extent?
