1) In 2017, 16 bison were released into Elk Island National Park. Within the next five years, 49 more bison will be released into the 1,200 km2 area. During the study period, it is expected that 45 calves will be born and 13 bison will die or be removed from the study area.



What is the expected per capita growth rate of the bison population during this study period?



Express your answer rounded to two decimal places. If the population is decreasing indicate this with a negative sign.






2) Three types of distribution patterns occur in wild populations of plants and animals. They are uniform, random, and clumped.

Choose from the drop down menus the statements and examples of populations provided to identify the correct distribution patterns.

Statements:
Organisms are grouped together; occurs in highly competitive environments.
No pattern exists in organism distribution; occurs in environments with little competition.
Organisms are equally spaced apart; occurs in artificial environments.
Examples:
Orange trees grow in rows on an orange plantation.
A large group of herring fish travel to their spawning grounds.
Oyster larvae are dispersed over hundreds of kilometres by strong sea currents.
