What do we mean by diversity?

The extinction rate increases with increasing species number. This is expected because more species implies greater comp ...

Fishhook Waterflea *Detected in Michigan*

The long tail spine and barbs make this zooplankton less appealing to planktivorous fish, so population regulation from predation is unlikely to occur. This could have a serious effect on planktivore f ...

... Distribution refers to how individuals in a population are spaced out. There are three recognized distribution types: 1. Random- Spaced out sporadically in an area (flowers in a field) 2. Uniform- Set distance between each (nesting sites) 3. Clumped- tightly packed pods or groups (school of fish) ...
