When species that are not closely related develop similar traits as a result of adaptations to similar environments, it is called:
adaptations
convergent evolution
trophic interactions
allopatric speciation
The páramo ecosystem has high levels of endemism. What ecological factors could the plants be responding to? (select all that apply)
intense ultraviolet radiation
drying effect of wind
rapid heating and cooling of climate
heavy grazing of alpacas
These alpacas are standing in what type of páramo?
subpáramo
superpáramo
grass páramo
pasture páramo
Some páramo plant species retain their dead leaves. Why?
tussock grasses
freezing avoidance mechanism
decrease biomass accumulation
to provide homes for insects
What are the two most important benefits of the páramo?
organic carbon storage
pastures for grazing
surface water
the views
Which of the following ecosystems has the highest carbon storage capacity?
rainforest
cloud forest
páramo
dry forest
mangrove forest
Island biogeography theory tells us that smaller islands closer to the mainland will have higher species richness.
True
False
What is this graph telling us about the relationship between species richness and area?
bigger areas have more species
bigger areas have fewer species
smaller areas have more species
smaller area have fewer species
Near islands have more species than far islands.
True
False
Islands experience immigration and extinction. When immigration equals extinction, the island has reached an:
equilibrium point
species richness point
a point of no return
an island biogeography
When an ecosystem is subdivided into patches (of varying areas) and is isolated to some degree from other patches it is called:
island biogeography theory
allopatric speciation
deforestation
habitat fragmentation
Select all that apply to edge effects:
changes in light, humidity, temperature, wind speed at edge
changes in biological processes (litter decomposition, nutrient cycling, structure and composition of vegetation)
changes in access to forest
changes in landscape conversion
The hydrologic cycle is driven by...
wind
evaporated water
oceans
solar energy
Mangrove forests are a transitional zone between...
mountains and ocean
dry forest and ocean
land and ocean
rivers and lakes
The term "mangrove" is not a taxonomic term but rather a term based on the physiological adaptations of a group of plants.
True
False
Mangroves are strongly adapted to life in:
the fast lane
shaded forest
salt water
rivers
Select all of the following benefits/ecosystem services of mangrove forests.
improved water quality
reduces erosion
protects shoreline
essential habitat for many fish species
carbon storage
In mainland Ecuador, what has done the most damage to mangrove forests?

alternative source of photosynthesis
green is in fashion
low absorption of solar radiation
Some animals in the dry forest go into "summer hibernation" which is called:
sleeping
