Microbial Ecology 1
Micro Ecology Class
| Term | Definition |
|---|---|
| Progenote | Extant life is what has survived extinction;pre-prokaryote ancestor |
| Microbial Acutecology | the study of microorganisms in the their environment |
| Environmental (Abiotic) conditions | Temperature, pressure, salinity, oxygen state, pH, UV radiation |
| Microbial Synecology | the interaction of populations with each other |
| Resources | Subject to competition and consumption;space habitat, water, oxygen, light, nutrients, carbon etc |
| Oligotroph | An organism that can live under conditions with very little nutrients |
| Copiotroph | An organism that lives under conditions with high amounts of nutrients |
| Photo/chemo-taxis | biochemical sensing of the environment |
| Allochthonous Microbs | Microbes that are foreign and not typical found in the habitat in question. Allo meaning foreign |
| Autochthonous Microbs | Microbs that are local and are always found in that particular habitat |
| Terrestrial Lithic Habitats | Rock surfaces: cyanos and lichens Cryptoendolithic communities: inside rocks |
| Soil Texture types | Silt, Clay, Sand |
| Soil Microbes | Mostly Gram-negatives: Pseudomonads,Agrobacteria,Myxobacteria Some Spore formers: Bacillus, actinomycetes Crenarchaeota; Fungi:saprophytes and mycorrizae Protist:protoza and algae |
| Phytoplankton | Primary aquatic producers |
| bacterioplankton | Secondary aquatic producers |
| Microzooplankton | Secondary/tertiary producers |
| Limnology | Study of Freshwater habitats |
| Lentic | Still waters such as ponds and lakes |
| Lotic | Running waters such as rivers |
| Oceanography | Study of ocean: Open ocean vs Near shore |
| Neuston | Surface layer film of microbes that forms under calm conditions such as algae |
| BOD | Biochemical Oxygen Demand-Measure of organic material that can be respired |
| Thermocline | physical separation between the warm surface waters and the deep cold waters |
| DOM | Dissolved Organic Material |
| Epipelagic | Surface layer of the ocean, warmer temps more light |
| Marine Snow | Particles that drop to sea floor made up of organic material |
| Aquatic Microbes | mostly gram negative:motives pseudomonas,flavobacteria Fungi: yeasts Protists: flagellates Viruses |
| Barophiles | bacteria that can only survive under pressure |
| White Smokers | marine hydrothermal vents that emit white smoke. only up to 73 degrees |
| Black Smokers | marine hydrothermal vents that emit black smoke. Up to 400 degrees |
| Thermophilic |
