BIOMES EGYPT

Egypt's major biome is desert. South Africa's latitude and longitude is 26° 00' N and 30° 00' E

Abiotic factors:

  • Temperature:In the coastal region average annual temperatures range from a maximum of 37° C (99° F) to a minimum of 14° C (57° F). Wide variations of temperature occur in the deserts, ranging from a maximum of 46° C (114° F), during daylight hours, to a minimum of 6° C (42° F) after sunset. During the winter season desert temperatures often drop to 0° C (32° F).
  • Annual precipitation is 200 mm
  • Deserts are generally close to the equator, therefore the sun permeates the soil causing the water to evaporate and the nutrients to die. This causes few plants able to withstand these harsh environments
  • Sand that has low bacterial activity

KEYSTONE SPECIES
Honeybees are considered to be a keystone species in Egypt and many other parts of the world. If the honeybee population continues to decline at the current rate, honeybees will cease to exist by 2035. There is no artificial substitute for pollination that would be able to counteract the extinction of honeybees. If honeybees became extinct, most of the land ecosystems of the world would collapse and a good part of humanity would perish along with them.

DANGERS TO THE NILE RIVER IN EGYPT
Due to heavy human extraction and high evaporation, the Nile river basin and its inhabitants are especially sensitive to climate change. Current water withdrawal for irrigation is so high, that despite its size, in dry periods, the river does not reach the sea. Climate warming models provide diverging pictures of future river flows in the Nile from a 30% increase to a 78% decrease. In addition, saltwater intrusion into coastal freshwater resources (including aquifers) is likely to increase as a result of sea-level rise due to climate warming and would further reduce the availability of freshwater in the delta region.The Nile basin traverses the largest number of countries of any basin in Africa; changes in the timing and availability of water under climate change may lead to tension, insecurity and management problems.

BIOMES SOUTH AFRICA

Biomes include Savanna, Thicket, Grassland, Forest, Fynbos, Nama Karoo, Succulent Karoo and Desert. South Africa's latitude and longitude is 29° 00' S and 24° 00' E

Abiotic factors:

  • Average Temperature 20-30 degrees C
  • Annual precipitation is 100-150 cm
  • Few natural barriers causing high winds
  • Rainfall is concentrated 6-8 months of the year
  • Porous soil with rapid drainage of water
  • Rolling grassland

Major Autotrophs:

  • Proteas
  • Fynbos
  • Ericas

Major Heterotrophs:

  • Elephants
  • Lions
  • Rhinos
  • Leopards
  • Buffalo

Decomposers:

  • Earthworms
  • Protozoa
  • Nematoda

KEYSTONE SPECIES
African rhinos are considered to be a keystone species in South Africa due to new research that shows they selectively browse on certain grass species, which leaves room for others that otherwise could not compete to move in and promotes more diverse edible plants.

DANGERS TO SOUTH AFRICAN GRASSLAND
The grassland area in South Africa is home to several animal species including 15 (45%) of South Africa’s endemic mammal species, 10 globally threatened bird species, 52 of the 122 Important Bird Areas in South Africa, and some endemic fish species. The biodiversity and the ecosystem services that the grasslands produce, are under significant pressure. Of the 80 vegetation types in the South African grassland biome, 2 are listed as critically endangered. Without this biodiversity, multiple other species will begin to decline, potentially leaving the grassland areas with hardly any species at all.

Keystone Species:
The African Lion is a keystone species in Nigeria. Its helps maintain a healthy ecosystem by regulating the populations of large herbivores such as buffalo, zebra, and wildebeest. This helps to ensure that the vegetation is maintained and not over-eaten. The lion is also a cultural symbol of Africa and the Savannah.

Dangers to Nigerian rainforest:
Nigeria's tropical rainforest are home to a wide variety of species including chimpanzees, leopards, cross river gorillas, elephants, monkey, parrots, and a wide variety of other animal and plant species. The rainforest in Nigeria are suffering from logging, agricultural fragmentation, fires, and the expansion of human populations. Many species found in the rainforest are suffering from forest degradation. If deforestation is continued at the current rate in Nigeria, there will be no more rainforest in Nigeria by 2020. Many habitats are still unprotected by the government and are continually degrading. One of the main rainforest preserves in Nigeria is the Cross River Preserve, which holds 50% of what is left of Nigeria's rainforest.
