Bio final

QuestionAnswer
organismal explores the morphological, physiological, and behavioral adaptations that allow individual organisms to live successfully in a particular area
population group of individuals of the same species that live in the same area
community species that interact with one another within a particular area
ecosystem consists of all the organisms in a particular region, along with nonliving or abiotic components
global encompassed by the biosphere, the thin zone surrounding the earth where all the life exists
conservation biology effort to study, pressure, and restore threatened population, communities and ecosystems
biogeography study of how organisms are distributed geographically
biotic factors interactions with other organisms, competition, reproductive requirements, parasitism
abiotic factors weather, temperature, moiture, seasons-sunlight, wind
Tropical Wet Forest favorable year-round growing conditions very abundant plant growth, leading to high above ground biomass
subtropical dessert high average annual temperatures, very low precipitation species adapt to extreme temperature, slow growing rate
Temperate grasslands to dry to enable tree growth or encroaching trees are burned by fires, plant growth: spring, summer, and fall months
temperate forest monthly temperature all below freezing and plant growth stops, precipitation is moderately high and constant
Boreal Forest Subartic lands south of Arctic Circle, very cold winters, short cool summers Species-long-lived
Arctic Tundra arctic regions and sold are perenially frozen (permafrost) growing season: 10-12, dominated by small woody shrubs, lichens, and herbaceous plants, low productivity
Anthropogenic Biome Farming, logging and urban development
lakes and ponds driven by wind and changes in temperature, cyanobacteria, and algae
Wetlands shallow-water habitats where soil is saturated with water for at least part of the year.
Bogs low nonexistent water flow, acidic ad nonproductive
Streams movec constantly in one direction; Creeks- small streams, rivers are large
Estuaries where rive meets the ocean and fresh water mixes with salt water -saline marshes - species cope with variations in salinity
oceans continuous body of salt water
Photic intertidial of sunlit regions of the neritic, oceanic and benthic zones
Aphotic areas that do not receive sunlight
Interidal zone beach
Neritic zone gently sloping, submerged portion of continental shelf
Oceanic zone deep water region
Benthic Zone bottom of the ocean
Which zones are the most productive? Interitidial and Neritic
Which one corresponds to the deep open ocean? Benthic Zone
Metapopulation population of populations connected by migration
How does it affect the population dynamics? more species are being forced into a metapopulation structure
How demographic changes? populations grow due to birth and immigration populations decline due to death and emigration
survivorship portion of offspring produced that survive on average to a particular age
Type 1 curve high survivorship, mot approach a max life span (humans)
Type 2 curve most experience constant survivorship (songbirds)
Type 3 curve high death rates, early life (plants)
Fecundity number of female offspring produced by each female in population
trade-off fecundity grow quickly, reach sexual maturity at a young age, produce small eggs and seeds
what factors affect the population cycles? density-independence and density dependent factor
Zero population growth is a condition of demographic balance where the number of people in a specified population neither grows nor declines, considered as a social aim by some
biodiversity tree of life
what are the two factors that affect biodiversity? speciation, extinction
3 types of diversity genetic diversity species diversity ecosystem diversity
where is biodiversity the highest? Tropical Rain Forest
What are endemic species? species that are found in a particular area and nowhere else.
What is biodiversity hotspot Regions that contain at least 1500 endemic plant species that are found in a particular area and nowhere else.
what are endangered species? a species of animal or plant that is seriously at risk of extinction.
Habitat Fragmentation breakup of large, contiguous ares of natural habitat into small, isolated pieces
overexploitation Any unsustainable removal or wildlife from the natural environment of use by humans
invasive species nonnative species that is introduced to a new area
Resistance measure of how much a community is affected by a disturbance
Resilience measure of how quickly a community recovers following a disturbance
benefits of biodiversity resource use efficiency facilitation camping effects
How can we achieve conservation sustainability management plans seed banks conservation wildlife corridors
