AGU 2016 Talks and Posters

AMERICAN GEOPHYSICAL UNION ANNUAL MEETING; DEC 12-16, 2016, SAN FRANCISCO, CA

CIRMOUNT-Sponsored Session, Dec 14, 2016:
Session title: Climate-Influenced Species Range Shifts: Where Are We Headed?

Under warming climates, poleward and upslope migration of biota is the widely projected and often observed response. However, as species range shifts are more closely investigated, more complex relationships are emerging. In some cases, there are long delays in poleward/upslope migration with warming. At shorter intervals, responses also include changes in demography, mortality, species interactions, community composition, structure, and species diversity. In other cases, responses include downslope shifts, movement to new aspects, movement or contraction into climate refugia, or no shift at all. These responses have been explained by a combination of forces related to climate and climate interactions with other abiotic and biotic factors. We invite contributions that explore climate-influenced range shifts from any taxonomic group, historical or contemporary cases, worldwide. We hope thereby to advance comprehensive understanding and improve projection of species range responses to warming.
