Document Summary

Generalists: species are associated with a broad range of environmental conditions. Specialists: found in a very narrow range of conditions only. Brine shrimp: invertebrates phylum arthropoda aquatic crustaceans genus artemia live in high salinity environments like shallow salt lakes and evaporation ponds generalists. Habitat selection/habitat preference: preference for particular level of environment. Sigma ( ) indicates that you need to sum the values to the right of the sigma. Observed the number of an organism counted. Expected the number you expect to find in the same section if h0 is true. The larger the x2 the lower the probability the difference between o and e frequencies are due to random variation in the data. 5 df [total number of categories] 1. X2 calc > x2 crit so p < 0. 05 and we can rejecr ho. Divided into two groups: basal animals: phylum porifera (sponges) have no true tissues, eumetazoa: true animals that have true tissues.
