Document Summary
We can observe similar species and environments across the world in different continents. We can look at phylogenic trees to see relationships between species. Ecology helps to predict distribution shifts in response to global change. For example, algae blooms are monitored and predicted. Predicting blooms is related to the interactions between species and the environment. *complications include having different species of algae and their different relationships with their environment. *as temperature increases, the window of possible algae blooms increases drastically. Usual window is from july-sept; +2c increase leads to window from june-oct. *timescales demonstrate how long-term certain variables affect algae bloom. Parasitic relationships parasites (mistletoe) and mesquite trees. Parasites are less likely to kill their host than just independent competitors. Predator: predator consumes resource in one moment: death happens in an instant. Parasitoids: partially consume resources initially, but then later kill their hosts.
