Document Summary
Bioc63fall2013 lecture 17: species and landscape approach to conservation. Mvp: best generalized estimate of minimum population size to survive catastrophic events into the future. Mvp affected by natural catastrophes, genetic factors, environmental uncertainty, demographic stochasticity. It is a rough estimate 8500 individuals for one species to survive, can estimate that for another species, with similar needs, a similar number of individuals would be required in order for the species to survive. Pva: fate of a population or species over a specified time period based on the growth rate assessed. Mvp uses past data whereas pva predicts future. At the landscape level what comes more into play is the heterogeneity of the landscape. Landscape approach landscape approach example: change would need to be made at the whole landscape level (greed shaded area) in order to change something in the delta. Most meaningful approach but hardest to implement.
