A community ecologist who is counting the number of Richness
different bird species in a park is measuring:
Evenness
Richness
Shannon index
Relative abundance
Which of the following is an example of an indirect effect Willow trees growing more densely due to wolves preying on elk
in a community?
A coyote catching and eating a rabbit
A bee pollinating a flower while gathering nectar
Two species of barnacles competing for space on a rock
Willow trees growing more densely due to wolves
preying on elk
A research team is studying a population of crested microevolution
anoles (Anolis cristatellus) living in cities. They found that
the anoles have evolved longer limbs for sprinting across
open areas. Using whole-genome sequencing, they
found that the physical changes are correlated with
selection on certain genes. This change in populations is
an example of
artificial selection
sexual selection
macroevolution
microevolution
, Genetic drift always leads to the adaptation of a False
population to its environment.
True
False
The Shannon Index differs from measuring richness by Including relative abundance values
Incorporating differences in species identities between
communities
Including relative abundance values
Weighting abundant species more highly than rare
species
Requiring three or more communities for comparison
Match the interaction type with its correct +/- notation. +/+ , +/0 , -/- , +/-
Mutualism
Commensalism
Competition
Predation
A keystone species is best defined as a species that: Substantially affects the structure of a community in comparison to other taxa
Is the most abundant organism in the environment
Substantially affects the structure of a community in
comparison to other taxa
Has the highest number of direct interactions in the food
web
Is the first species to colonize an area after a major
disturbance
Select the examples that represent ecotones: The edges of a recently burned patch
The deep zone of the open ocean The riparian zone where a forest meets a river
The edges of a recently burned patch
The riparian zone where a forest meets a river
The core of a large, contiguous tropical rainforest
