1. Habitat fragmentation
General concept -
- an expansive ecosystem is carved up into smaller pieces by roads, buildings, other structures and human activity
- claim from somewhere - can't remember -
- In the USA you're never more than 40 miles from a road.
- Never more than 18 miles from a human built structure (radio tower, etc.)
- but the terms are used many ways
go through Fahrig
- the term is used many ways
- how is it used in practice - look at many articles
- if it's used too much and too loosely it looses meaning, that ability to differentiate or to add information
- ecology and especially environmental science are ill-structured domains of knowledge
this type of article makes a very important contribution
- review of what's been done
- synthesis and some evaluation/categorization
- others on problems, uncertainty, etc.
- makes it possible to bring more disciplines into address the question
Network description
- network parameters, in particular connectivity
- critical size using simulations
- forest fire metaphor - critical densitity and connectivity -
- intermediate connectivity is best (some disturbances keep it from becoming crystalline)
