Migrations Flashcards
What is the Great Acceleration?
Steinbauer et al., 2018
Globally accelerating trends in societal development and human environmental impacts since the mid-twentieth century
What locations are particularly sensitive to ecological change?
Steinbauer et al., 2018
Mountains are particularly sensitive to ecological change and are experiencing some of the highest rates of warming under anthropogenic climate change.
The accelerated increase in species richness on mountain summits is likely to result from…
Steinbauer et al., 2018
an upward shift in the upper range limits of an
increasing number of species.
Plant altitudinal changes
Wolf et al, 2016
The differential responses of plant species to climate change are of great interest and concern for scientists and conservationists
Plant migrations to climate change
Parmesan, 2006
A global review shows that 41 % of species studied have shifted their species’ ranges poleward and/or upward.
Observed Impacts in range shifts in mammals
Rodnikova et al, 2011
Red fox (Vulpes vulpes) is expanding into the arctic habitats. Arctic fox (Vulpes lagopus) has contracted to Atlantic.
What is an ‘invasive’ species?
Masters & Norgrove, 2010
Invasive species are species that affect, economically, environmentally or ecologically, habitats where they have been introduced, either accidentally or deliberately, outside their normal past or present distribution
Invasive species and climate change
Pauchard et al., 2009
1) Mountain plant communities are not particularly resistant to invasion by exotic species.
2) New species, that may become invasive, will be entering regions due to climate change.
3) Climate induced stress in an ecosystem will facilitate invasive species arrivals
Geological record shows coral distributions have changed with changing climate
Precht and Aronson, 2004
Pleistocene regressions and transgressions – coral species moved ranges by 100s km in some regions as sea level changed and as ocean waters warmed and cooled.
