Regular logistic growth - Answer-Goes up exponentially then plateaus Niche - Answer-The range of abiotic and biotic conditions an organism can tolerate/handle Fundamental niche - Answer-the range of abiotic conditions under which a species can persist Realized niche - Answer-the range of abiotic and biotic conditions under which the species can persist fundamental/realized niche of american chestnut - Answer--Fundamental niche: Is climatic and soil conditions throughout eastern USA. - Real...

Give an example of spatial heterogeneity of ecosystems in a region. Human land-use change has fragmented landscapes, shifting the balance so that managed patches become the matrix in which small fragments of less managed lands persist What are biogeochemical hotspots and what type of biogeochemical hotspot is a beaver pond? have high process rates. Beaver ponds have high methane emissions. Give an example of variation patch shape, configuration, connectivity, and metapopulations in a real ecos...

Characteristics of mainland-island model CORRECT ANSWERS: mainland doesn't go extinct one way dispersal from mainland to island no movement between islands Model assumptions for classic metapopulations CORRECT ANSWERS: homogenous patches, all patches likely to be colonized, each patch has own local dynamics (C and E are asynchronous) Doubling time CORRECT ANSWERS: tdouble= ln2/r when lambda constant pop grows CORRECT ANSWERS: lambda= Nt+1/Nt relating lambda to r CORRECT ANS...

What are Metapopulations? - ️️Isolated 'populations' that are connected by immigration / emigration (via dispersal) What is a sub-population? - ️️Each distinct component of a metapopulation. What is a disturbance? - ️️A temporary change in environmental conditions that causes a pronounced change in an ecosystem (extent, severity, frequency) What are some types of disturbances? - ️️1. Fire 2. Insect Outbreaks 3. Windstorms 4. Volcanoes What is primary succession? ...

If Earth had no oceans, would temperatures at the equator be hotter or colder than they are now? Temperatures would be hotter Temperatures would be colder. Temperatures would remain the same. This question can't be answered without additional information. - ANSWER-Temperatures would be hotter If the Earth spun on an axis that was perfectly perpendicular to the equator, then the poles would receive the same amount of solar energy as the equator. true false - ANSWER-false If the Earth...
