terrestrial eco P MT

practice for the terrestrial ecoststems mid-term at fleming college

QuestionAnswer
An event that changes the state of an ecosystem and influences ecological processes Ecosystem disturbance
The natural (or non natural) transition from one ecosystem state to another, characterized by biological and chemical processes and components Succession
Study of interactive relationships between fire and biota and chemical processes within an ecosystem Fire ecology
Fire, wind, water, polution, mechanical impact and pathogens Examples of ecosystems disturbances
In order for forest succession to start again there needs to be some sort of ______________ Disturbance
Climate soil nutrient status Seed disbursal capabilities Animal herbavory Allelopathy Site condition that are vital in species establishment
Highlight environments Increased temperature High wind velocity Low soil moisture High nutrients Shade intolerant plants Early succession
Lower light environments Thicker canopies Less soil nutrients Increased soil moisture Moderately shade tolerant plants Mid succession
Low light conditions Cooleer site temperatures Lower soil nutrients Moist soils Shade tolerant plants Late succession
Theoretically, should be highest in patch areas of forest typically, this is characteristic of early successional stages Diversity can increase with gap creation. Biological diversity
_______________ is often characterized by biological diversity because of abundance of resources Early succession
One of the most important initial steps for forest succession is fire Fire is a natural and neccessary part of the ecosystem Fire ecology
Fire is essential for ______________ forest regeneration Boreal
______________ reproduction is dependant on fire however fire intensity matters Jack Pine
When fire burns trees, what nutrients does it release? Nitrogen, mercury and sulpher
Dependant on fire for maintenance and structure If fire is excluded from the ecosystem, shrubs will invade, facilitating forest succession The relationship between Black oak savannah and fire
Have lower species richness and smaller populations Small forest fragments
Provides more channels for species to colonize Large islands/forests
What does MVP stand for? Minimum valuable population
Minimum threshold of individuals that will ensure that a population will persist in a viable state for a given time Ability of a species to resist a certain stressor and have the ability to recover their populations Minimum valuable population (MVP)
Not many offspring; many resources needed to survive K strategists
Many offspring; less resources to survive r strategists
Forests are fragmented, there is an increase in edge habitat Forest fragmentation
Transition zones between ecosystems; narrow Ecotone
Inherent/natural feature Inert edge
Found where two succession stages meet Short term phenomenon Induced edge
Can increase diversity and species richness but many of these species can be invasive species; intact edges provide more protection An edge
Refers to area Edge size
___________ from buffer zone is the interior of the forest 100M
All life on earth is created by _____________ energy The sun
Flora and fauna in terrestrial ecosystems adapt to these changes in ______________ inputs Solar radiation
Refers to a part of an ecosystems that traps carbon A carbon sink
Refers to a part of an ecosystem that releases carbon Carbon source
Total amount of carbon fixed by leaves Gross photosynthesis
Amount of carbon released via leaf metabolism Leaf respiration
Gross photosynthesis minus leaf resporation Net photosynthesis
Amount of carbon used by other parts of the plant or cell funtion Non leaf resporation
Photosynthesis used to create oxygen molecules Net primary production
NPP stands for Net primary production
NPP minus decomposiiton Live biomass acumulation
Growth and reproduction Net secondary production
How do we date the earth? Argon 40
