A Very Brief Introduction to Ecology

This is a transcript of an information sheet I have knocking around. No idea where I got it from.

Ecology
from the Greek Oikos meaning ‘home’+ology meaning ‘study of’
Quick definition
the study of the distribution and abundance of organisms in their environment
Ecology as a science
employs the scientific method to establish principles and theories about the living world.
Sources of evididence
field observations and measurement; field manipulations and experiment; laboratory and microcosm experiments; computer simulations and models;historoc data;genetic data;commercial and official data

Levels of organisation

AutoEcology
the ecology of individual species in their environment
Population Ecology
processes determining growth, decline, fluctuation of stability in populations (groups of same species individuals)
Community Ecology
study of groups of organisms living together.
Ecosystem Ecology
study of groups of organisms and the non-biological environment in which they live
Related disciplines
evolutionary biology; conservation biology, restoration ecology; economics

Key Concepts

Root and Branch

In this wittily written piece in the Washington Post, by its Pakistan bureau chief Tim Craig, a diplomatic controversy concerning trees in Islamabad shades, as trees tend to, the presumably undisclosed reason why the US embassy there is expanding. This expansion is cleverly hidden like a nugget in the article, halfway down at least, after a charming picture is painted of the city as one of the greenest, where landowners must get state permission to remove trees, all set in a palace of alternating parkland.

The description of ecological regulations in the city didn’t surprise me but did seem slightly at odds with what I’d heard about some unchecked urban development and so on in, I guess, the rest of the country. Indeed, careful to avoid the impression of being a PR job for Pakistan’s ecological reputation the article concludes by drawing attention to Pakistan’s ecological problems; deforestation and the possible relationship with flooding.

Nevertheless this due journalistic diligence does seem a little like a segue away from the key question, only briefly considered in Mr Craig’s piece: what drives the US embassy to expansion, and is it really that secret?
