Bio Test final
| Question | Answer |
|---|---|
| Species Richness | the number of species in a community |
| Species Diversity | the relative abundance of individuals within a species |
| Evenness | similar frequencies of each species |
| Dominance | one or two species greatly outnumbering others |
| Climax community | a stable group of plants and animals that is the end result of the succession process |
| Early Succession Traits | dispersal capability and the ability to withstand harsh conditions |
| Species arrival | Animal dispersed, wind dispersed, sea dispersed |
| Equilibrium | species number defined by available resources (habitats, niches) and maintained by colonization and extinction |
| Ecology | the study of interactions between organisms and their environment |
| Anthropocene | Scientists are starting to refer to this new human-altered period |
| Ecosystem | consists of the multiple communities of organisms that live in an area, in association w/ its abiotic components (soil, climate, water,atmosphere)- flow of energy and nutrients |
| Hubbard Brook Ecosystem Study | A herculean collaborative project to understand forest ecosystems by actually manipulating them at the scale of whole watersheds |
| Erode GPP efficiency | 1. chlorophyll pigments can’t absorb, 2. deciduous plants, needled plants, 3. cold temps limit photosynthetic enzymes, 4. hot/dry weather closes stomata |
| Rule of 10 | Due to inefficiencies only 10% of energy passes to the next trophic level (cold blooded animals are better at conserving) |
| FACE | free-air CO2 enrichment experiments |
| Conservation Science | the discipline of studying and managing nature (species or habitats) with the aim of maintaining or returning their numbers/health to viable status |
| Long-term resource | Plants & wildlife are renewable natural resources. Meaning they replenish their populations through biological processes. |
| Management | Manipulation or protection of a population to achieve a goal |
| Value judgments | What to do? |
| Technical judgments | What actions are most likely to achieve those goals? |
| Conserving species | drugs, pollination, indicators, |
| Ecosystem Services | benefits that humans Conservation Biology receive from natural environment from a functioning ecosystem (provisioning, regulating, cultural) |
| Bio-prospecting | the process of discovering new biological compounds or resources that are useful for some problem… with an eye towards commercialization |
| Instrumental value | economic, ecological or wellbeing-related importance |
| Intrinsic value | nature has value as an end in itself |
| GPP | Gross Primary Productivity |
| NPP | Net Primary Productivity |
| NDVI | Normalized Difference Vegetation Index- remote sensing metric that measures plant health and density by analyzing light absorption |
| Fluxes | Processes: photosythesis, respiration, decomposition, combustion |
