Question

list the four properties that scientists use to predict population sizes. Also, include the definition of each of the properties. Define the type of scientists that study populations.

Answer 1

well they are called Demographers and study of population is called demography
current population species

- genetic diversity (e.g. cheetahs have a low genetic diversity, however they have evolved to minimise the effect this has on birth defects, however low genetic diversity typically makes a population less resislent to viruses)

- habitat fragmentation/contiguity (i.e. can the population move to other habitats, either for breeding, migration, feeding, or because of loss of habitat)

- climate (and perhaps climate change) (e.g. if temperatures warm will the populations increase/decrease, if rainfall declines will the species persist - especially important for plant populations - also could be a factor if fires are a related side effect, as
many species have evolved to a particular fire regime and changes in this fire regime may affect populations)

topography (e.g. elevation, aspect, terrain) (I did a study on predicted the distribution of a tree species, and statistically topography was important, as the species was able to outcompete other species at a higher attitude and the inverted tree line also limited the species population)
- influence of predators or competition (e.g. if fox populations are modelled to increase the rabbit population could be modelled to have a short-term decline) :D
