Climate Generalist Butterflies Expected to be Winners Under Climate Change in Canada
Forecasting species responses to climate change is integral to the development of adaptive and practical conservation decisions. Butterflies are climate-constrained in at least two ways, as ectotherms, the climate has a defining role in dictating where butterflies can live. Additionally, a warming climate may have huge impacts on their host plant availability. These constraints could mean certain butterfly species may have to move north, or up in elevation, to stay within their preferred temperature range. Predicting how butterflies might respond to such temperature and host plant shifts could inform decisions involving conservation prioritization, species management, and natural resource management.
(English) A Giant Leap for a Butterfly in Vermont and Beyond
(English) In 2010 when the largest butterfly in North America fluttered among Ardys Fisher’s flowers at the end of July, she knew it was something neat. Now, our study published in Frontiers in Ecology and Evolution this week shows an unusually rapid northward range shift by the Eastern Giant Swallowtail over the last two decades.
Papillons : la quête du Saint-Graal
For every butterflier, I would be willing to bet that over the years, when out on field trips, you have had some ‘special’ butterflies in mind that you hope to come across – in other words, ‘Holy Grails’ or, simply, grails.
