Temperate Biomes
| Term | Definition |
|---|---|
| Norther temperate zone (L) | Legacies of the last glaciation |
| Norther temperate zone (#) | Tremendous # of lakes |
| Norther temperate zone (B) | Many are in the boreal forest |
| Temperate biomes | four seasons, generally mild temperatures, and sufficient precipitation to support high rates of primary/secondary production |
| Costal wetlands | dominant feature of GL shorelines |
| Wetland types differ by | Geology Shoreline configuration Soil chemistry and texture Surface water input and water level fluctuations Groundwater |
| Seiches | standing wave in which the largest vertical oscillations are at each end of a body of water |
| Bioaccumulation | An increased concentration of a chemical within an organism over time |
| Biomagnification | accumulation of pollutants at successive levels of the food chain |
| Cultural eutrophication | Nutrients from agriculture and livestock |
| Pervasive changes | Bacteria to top level predators |
| eutrophication causes | Sewage pollution/runoff |
| Eutrophication | excessive richness of nutrients in a lake or other body of water |
| Stratification | is an annual process dependent on water temperature (density) and wind strength |
| 1. Epilimnion | the upper layer of water in a stratified lake. |
| 2. Metalimnion – Thermocline | thin but distinct layer in a large body of fluid in which temperature changes more drastically |
| 3. Hypolimnion | lower layer of water in a stratified lake, typically cooler and stagnant |
| 4. Monimolimnion | lower, dense stratum of a meromictic lake that does not mix with the waters above. |
| hypoxia | low levels of oxygen |
| Eutrophication and algae blooms | dead phytoplankton/zooplankton |
| Lake Erie stratified | Summer |
| Invasive species How did they get there? | Pet trade Plant nurseries |
| Predation | (+/-) |
| Interspecies competition | (-/-) |
| Functional responses | Fewer food = less feeding More food = more feeding |
| Numerical response | More food = calling over “friends” growing the population |
| Competition | Simultaneous demand for limited resources that impact fitness of the species |
| Interference competition | Direct interactions |
| Exploitation competition | Indirect interactions |
| Trophic web impacts | Trillions of zebra and quagga mussels filter the entire water volume of the Great Lakes every few weeks |
| zebra and quagga mussels | Water clarity doubled in the last 2 decades Reduced productivity at the bottom of the food web |
| Predatory zooplankters (B) | Bythotrephes |
| Predatory zooplankters (C) | Cercopagis |
| Predatory zooplankters (E) | Egg Predators |
| Trophic and ecological impacts | Sea Lamprey |
| Sea Lamprey | Crashed Lake Trout stocks Impacts salmon and other large species |
| Common reed | Likely introduced by soil ballast |
| Common reed - Multiple reproductive modes | Stolons Rhizomes |
| Extirpation of native wetland plants | • Reductions in wetland plant diversity • Changes in wetland function • Reduced processing of N |
| macroinvertebrate | larval or nymphal forms of otherwise terrestrial species |
| Ballast water treatment | Exchange/flushing |
| Revise Lacey Act | require screening of imported species for diseases/parasites |
| Asian carp colonization Silver Carp | phytoplankgtivore - 45kg |
| Asian carp colonization Bighead carp | zooplanktivore – 42kg |
| Asian carp colonization Black Carp | molluscivore – 35kg |
| Asian carp colonization Grass Carp | herbivore – 40kg |
| Asian carp colonization | Highly efficient Fecund Environmentally tolerant Few pelagic predators in the US are predators |
| The problem has developed | engineering solutions to connect the great lakes with the Gulf of Mexico |
| eDNA | tracking using left behind DNA |
| electric barriers | used to try and keep the carp out |
| eradication | is not feasible |
| Phragmites | Physical control |
| Lythrum | biological control |
| Phragmites & Lythrum | chemical |
| arboreal, pulmonate | What if the control misbehaves Bio-control – a warning |
| The most extensive invasive species control program in the GL is for | Sea Lamprey |
| Generalist species | r-selected species |
| Specialized species | K-selected species |
| r-selected species | Pest species |
| Short access | the specific thing it needs to leave |
| k-selected species | Short access |
| Niches | functional role of a species |
| N-dimensional hypervolume | Set of resource axes used by a species |
