MULU NATIONAL PARK Limiting Factor
  1. Water
    1. All terrestrial organisms hae inimum water requirement, stress, dehydration & death will occur.
      1. Plants & animal become adapt to high-water environment ( lakes)
        1. When water excess, relatively dry environment present for organisms,plants.
          1. due to water - logging leads to oxygen stress in soils & reduce activity of other biogeochemical cycles.
            1. plants also shift water from soil which then moved into atmosphere in gaseous through transpiration.
              1. living organisms occupy an environment have evolved mechanisms.
              2. Climate
                1. During transition period (dec - march) & (may- october)
                  1. controlled largely by Indo-Australian monsoon system
                    1. rainfall generally at afternoon & night
                      1. remain high during north-east monsoon , the south-west moonsoon ( July - Sep)
                        1. minimum temperature around dawn
                        2. Trepanon
                          1. Predator exert significant control over herbivors
                            1. Predator attract the weaken and strengthen the prey to evolve of entire spctrum of anti-predator detection & define mechanism
                              1. when 'alien' predators introduced into different ecosystem it will be a severe results of extinction.
                              2. Soils
                                1. on level flat ground, drainage-poor & gley soils of Bijat family occur
                                  1. Bijat family soils have higher pH & base saturation than other family.
                                    1. some soils not typical of red-yellow podzolic soils
                                      1. dicterocarp forest site- soils are heavy, textured red-yellow podzolics with surface layer of reddish, brown fibrous organic matter.
                                        1. surface organize matter layers unusually thick & similar to those more often found in light-textured soils.
                                          1. forest over limestone site soils are very shallow, highly organize 7 black with mull humus form
                                          2. Competition
                                            1. Food & space utilised reduced by other competition.
                                              1. Tourism & recreation result on transfer of plants & animals to location they are not normally occur.
                                                1. The 'alien' plants species often t advantage because new environment usuallly devored of any natural controls that invades would evolved
                                                  1. introduction of 'alien' plants result in discruption & improverishment of natural plant community.
