Ecology Lab Final

3 TYPES OF SPATIAL DISPERSION PATTERNS

-aggregated

-uniform

-random

What abiotic/factors promote aggregated distribution?

-social protection

- mating season

-resource rich region (shared resource)

-group hunting

What abiotic/biotic factors promote uniform distribution?

-territory

-resource-poor regions chemically space for resource equally distributed

What abiotic/biotic factors promote random distribution?

- overabundance of resources

-seeds dispersed in wind

plot-based field sampling for spatial dispersion?

record the dispersion by make a 25x25 plot and visiting coordinates

plotless field sampling for spatial dispersion?

at random plot points measure distance to the closest tree for dispersion

How does geographic scale influence spatial dispersion pattern?

The more space, the more resources and availability of space

-if a regional climate altered dispersion maybe larger geographic scale would need to be studied

species _________ and ___________ are needed to calculate biodiversity of area

richness, evenness

How do Shannon-Wiener Index and Simpson's Diversity differ?

Shannon-Wiener does not account for species abundance in diversity index. All species considered to same esteem whether 1 or 100

What are the primary disturbances influencing wetland habitats in Florida

-flooding

-period of time with water

How does wetland size correlate to biodiversity

- change the species evenness?

-changes the ecosystem included

How do Florida's salt marsh and mangrove wetlands differ in terms of the structure and function? What other types of wetlands exist in Florida?

salt marsh contain cordgrass (cold-tolerant, high tide) and mangrove contain red mangroves (better in tropical weather, low tide)

According to info, what 3 components make an ecosystem?

scale, structure, and function

What are some example of ecosystem services that tidal wetlands provide?

-sequester carbon

-protection from soil erosion

-reduce impacts of storm surge
