palm oil uses
food
pharmaceuticals
biofuels
1999-2008
56% increase in palm oil tree area
replacing dry dipterocarp forest
75-90 years
replacing peat swamp forest
600 years
functional diversity
quantifies the range and abundance of functional roles played by species within a community
examples of functional roles
food type (feeding guild)
body size
foraging strategy
bill shape
functional richness
volume of functional trait space occupied by a set of species
ecosystem services
the provision of a natural resource or process that is valued by humankind
higher functional richness equals
higher levels of ecosystem functioning
more efficient resource use by community
improved services that benefit humankind e.g. higher carbon storage with higher functional diversity
species climate niche
the specific range of climatic requirements that enables a species to survive and reproduce
bioclimate envelope models
help to understand species climate niches across earth and how they may change
5 steps to making a bioclimate envelope model:
- collect records of locations
- map current species distribution
- use distribution to infer environmental requirements
- predict a species distribution from its environmental requirements
- use BEM to predict future distributions under changing climates
phenology
the timing of seasonal activities of animals and plants
how has climatic warming impacted phenology
date of arrival of migrants
first and duration of appearance
first breeding
benefits of change in phenology due to warming
exploit favourable climates earlier in the year
early access to best nest sites and abundance of food = improved survival of young
potential to make more breeding attempts
