Q

What is the Great Acceleration?

Steinbauer et al., 2018

A

Globally accelerating trends in societal development and human environmental impacts since the mid-twentieth century

2
Q

What locations are particularly sensitive to ecological change?

Steinbauer et al., 2018

A

Mountains are particularly sensitive to ecological change and are experiencing some of the highest rates of warming under anthropogenic climate change.

3
Q

The accelerated increase in species richness on mountain summits is likely to result from…

Steinbauer et al., 2018

A

an upward shift in the upper range limits of an

increasing number of species.

4
Q

Plant altitudinal changes

Wolf et al, 2016

A

The differential responses of plant species to climate change are of great interest and concern for scientists and conservationists

5
Q

Plant migrations to climate change

Parmesan, 2006

A

A global review shows that 41 % of species studied have shifted their species’ ranges poleward and/or upward.

6
Q

Observed Impacts in range shifts in mammals

Rodnikova et al, 2011

A
Red fox (Vulpes vulpes) is expanding into the arctic habitats.
Arctic fox (Vulpes lagopus) has contracted to Atlantic.
7
Q

What is an ‘invasive’ species?

Masters & Norgrove, 2010

A

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

8
Q

Invasive species and climate change

Pauchard et al., 2009

A

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

9
Q

Geological record shows coral distributions have changed with changing climate

Precht and Aronson, 2004

A

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.
