An interesting talk from Dr Phil Stephens of the University of Durham. http://www.dur.ac.uk/philip.stephens/welcome.htm link to the university of Durham home page.
This afternoons talk gave an incite into mammalian population dynamics and the studies that go with them, The question of whether decline in prey plays a bigger role in carnivore abundance and declines.
Little is known about mammalian biology, compared to other animals (birds and butterflies) (Stephens, 2013). Improving the information on mammal species would provide important insights into their biology and physiology for conservation and management purposes.
mammal data comes from short scientific studies (less than 5 years) Also from long term studies. This bit of data sets comes from hunter. would there be a better way of collecting data rather than using data from hunters?
Long term data collecting can be expensive. Old data sets are often used, Could this lead to misleading information? Are the data sets correct?
To quote King (1997) “Data from old. possibly unreliable studies often results in the development of inaccurate conclusions regarding the empirical world”.
To gain an increased Knowledge of mammal populations perhaps previous studies should be carried out again, With the use of more up to date techniques?
I recently read an article addressing the impact on endangered species because of the increase in human populations
Researchers determined that by the end of the next decade the average growing nation should expect 3.3 percent more threatened species, a figure that will jump to 10.8 percent by 2050.
With this information, it then opens the question of Is the rise in human populations a major impact on mammalian populations?
