The document discusses biodiversity and taxonomy. It defines a species as a group of organisms that share genes and lineage, and are adapted to particular environmental resources. There are millions of species, many not yet identified. Taxonomy is the science of classifying species in a hierarchical system, from broad kingdoms to specific genera and species, to indicate natural relationships. This ordering system, developed by Linnaeus, helps organize the vast number of species and provides a standardized naming convention. The document also discusses how biodiversity supports ecosystem functions and is declining due to human-caused extinction rates being much higher than background rates.
3. There are multiple definitions.
2 useful ones for our purposes...
A set of organisms adapted to a
particular set of resources in the
environment

A group of organisms
that share a lineage,
and thus, genes at
some significant level
8. Keeping track
The science of naming and
classifying species in an ordered
system that indicates natural
relationships
9. Taxonomy assigns each animal in
a hierarchical classification system
First, identify a new species
Second, determine if the species already has a name
Third, assign a new, unused, name to the species
Fourth, notify a name authority of the new species
A system founded on the principles of Carl Linnaeus

32. Future of biodiversity
"There is medium confidence that
approximately 20-30% of species assessed so
far are likely to be at increased if increases in
global average warming exceed 1.5-2.5 deg C
(relative to 1980-1999). As global average
temperature increase exceeds about 3.5 deg C,
model projections suggest significant
extinctions (40-70% of species assessed)
around the globe."
