Document Summary
Evolutionary biology- how individuals have evolved and adaped to their environment through interactions with other individuals, populations and other species. Behavioural ecology how an individuals behaviours contribute to their survival and reproductive success and in turn the abundance in that population. Physiological ecology the sudy of how organisms are physiologically adapted to their environment and how this limits their distribution patterns. Population ecology the study of groups of interbreeding individuals at the same place/time. Water is most dense at 4 c and its least dense as ice (increases density with salinity) Epimilimnion: warmed b the sun and mixed well by the wind. Thermocline: transition zone wehre temperature declines rapidly. Hypolimnion: cool layer too far below the surface to be warmed with low light levels. Two types of food webs: benthic based macrophytic, pelagic based microphytic. Cultural eutrophication: biological oxygen demand (bod, dissolved oxygen (do): Do same at all levels of the water.
