FRESHWATER SWAMP FOREST Freshwater swamp forests‚ or flooded forests‚ are forests which are inundated with freshwater‚ either permanently or seasonally. They normally occur along the lower reaches of rivers and around freshwater lakes. Freshwater swamp forests are found in a range of climate zones‚ from boreal ecosystem through temperate and subtropical to tropical. 23 Freshwater swamp forest in the World: Afrotropic • Eastern Congolian swamp forests (Democratic Republic

Water pollution through urban and rural land use and freshwater allocation in New Zealand New Zealand has 425‚000 kilometres of rivers and streams‚ almost 4‚000 lakes larger than 1 hectare in size‚ and about 200 groundwater aquifers (Ministry for the Environment‚ 2010). By international standards‚ freshwater in New Zealand is both clean and in good supply. However‚ some aspects of water quality are getting worse in areas dominated by intensive land use. Demand for water is increasing‚ particularly

to be well evaluated. Acid precipitation has a long-term effect especially on the living organisms in many lakes and streams which sometimes causes extinction. Related Studies On the study of Schindler during 1988‚ Effects of Acid Rain on Freshwater Ecosystems‚ it was stated that there is an increase in number of areas most likely to be affected by acid. The study presented the biological damage caused by the acid rain‚ which includes the disappearance mostly of small fishes that are considered

because of increased water temperatures and runoff of silt from the land. 2. The two major aquatic life zones are saltwater (marine) and freshwater life zones. 3. Phytoplankton (plank plankton) are multiple types of algae; Zooplankton (animal plankton) are primary and secondary consumers which feed off phytoplankton (primary consumers) or other zooplankton (secondary consumers); these range from protozoa to large invertebrates such as jellyfish. Ultraplankton are much smaller plankton that may

The average salinity of ocean water is 35 parts per thousand. Ocean water is always more dense than freshwater. Density in the ocean gets greater the deeper you go. The Neritic zone is made up of the surface zone and transition zone. Applying the rule that density in the ocean gets greater the deeper you go you can safely assume that the density in the

An integrated study of the Mpenjati estuary-beach system. (Biological component) Abstract A study was carried out to find the abundances of animal organisms between both sides of the Mpenjati estuary. Zooplankton‚ Macro fauna‚ Meiofauna and Fish was sampled .Each of the species that reside in the estuary contribute to the diversity of the area and are essentially driving forces‚ ensuring optimal functioning of the ecosystem. The purpose of sampling such ecosystems is to find out how the interactions

Gerking (1994) also state that some fishes prefer phytoplankton and zooplankton (eg: plankton predator) and benthic predator more prefer pondweed and invertebrates living on the bottom as their nourishment. These show that food habits of the fishes fall into three categories‚ which is herbivorous‚ carnivorous and omnivorous

Zooplankton‚ a much smaller organism than the gray tree frog; the zooplankton wasn’t not able to survive in the water with high levels of salt. If the zooplankton die out then the body of water’s algae contented would increase but not only that‚ the fish that feed on zooplankton would die out‚ creating an imbalance in the food chain. The zooplankton get stressed in the high salt environment‚ just like humans get dehydrated

Each of these aquatic ecosystems can be defined by variables such as temperature‚ the presence or absence of light‚ and the availability of nutrients. Aquatic biomes cover almost all the world (around 75% of the surface) and only 3% of them are freshwaters. Freshwater ecosystems This ecosystem
