Macrophytes, phytobenthos and macroinvertebrates are the dominant communities in

littoral zone

profundal zone

pelagic zone

surface zone

Clear selection

Nome e número

When the water body has a lot of phosphorus in the water column, the dominant algae group is

greens

blue-greens

diatoms

flagellata

Clear selection

With a large precipitation in winter

conductivity decreases

conductivity increases

conductivy does not change

conductivity changes are dependent of the temperature

Clear selection

In eutrophic lakes on summer the variation in depth of the dissolved oxygen concentration and the temperature,

they do not vary in depth

have opposite curves of variation

have similar curves of variation

depend on the thermocline

Clear selection

In reservoirs, the dominant fish/fish sizes are

juveniles of barbel

diadromous species

adults of barbel

small cyprinids

Clear selection

the seuence of habitats in the figure is

riffle-pool

riffle-run-pool

riffle-run-canal

riffle-run-canal-pool

Clear selection

The figure can be used ro characterize a river network because *

it results from temperature variation

it measures river length and drainage area

the same numbers have the sae fish species

esach number has a different water volume

Highly productive reservoirs lead to the following fish distribution in summer

in the bottom layers

near the surface

throughout the water volume

in the tributaries

Clear selection

In a site large and with many submerse vegetation cover, the predominant macroinvertebrates are

scrappers

filterers

shredders

predators

Clear selection

Variables determining the habitats in the figure are

vegetation cover, turbulence and slope

velocity, slope and cover

velocity, depth and substrate

turbulence and dissolved oxygen

Clear selection

The vertical dimension of rivers refers to

the depth of the water

the connection to the aquifer and subterranean water level

thermal variation with depth

the bottom-dwelling organisms

Clear selection

Number of stratifications per year in portuguese large reservoirs

one

two

three

does not exist

Clear selection

In an oligotrophic reservoir in summer it is expected

accumulation of organic phosphorus in sediments

retention of total phosphorus in sediments

release of total phosphorus from sediments

release of organic phosphorus from sediments

Clear selection

Calcium, carbonates and sulfates are

evaporation derived components

rainfall derived components

small components from rocks

major water components

Clear selection

The animal depicted in the figure is

catadromous migratory

diadromous resident

potamodromous

it is not an inland species

Clear selection

In a small river with a lot of riparian vegetation, the predominant macroinvertebrate are

scrapers

filterers

schredders

deposit collectors

Clear selection

The width of the river channel is different from the river bed width in mediterranean areas most of the year because

aquifers are very deep

the valley is very dry

flow regime dictes fluctuations of water level

not true

Clear selection

In the aquatic biofilm

The dissolved and ultrafine organic matter flocculate

There are no macroinvertebrates but there are a lot of bacteria

the primary vegetation are plants

the dominant organic matter is the CPOM fraction

Clear selection

The concept of rivescape indicates that

fish populations must be sampled separately

fish conservation must be done at the segment and basin levels

we should give attention to downstream communities

fish species do not apply to the concept

Clear selection

The freshwater mussels is a threatened group because

over-exploitation for food

are very sensitive to organic pollution

it needs high flows

it has low resistence to climate change

Clear selection
