Biology Field Location

Description of the field Location

The field where our investigations were carried belonged to the region of Simijaca / Cundinamarca Colombia.  Simijaca has very template weather. It has sunny, dry and windy days, and cold, wet nights. We traveled several areas of Simijaca, such as high mountains; forestall paths which included rivers, tall trees and a variety of animal and plant species. We also spend time on plane areas where it was more common to see cattle herds rather than lots of plant variety species.

Depending on the area that we were located the abiotic and biotic factors changed. When we were on the plane area, the biotic factors present were:

  • The vegetation present. This includes grass, plant species (such as trees, flowers, bushes…) but in this case, was the cattle herd was located, only grass and some tress were present.
  • Competitors and predators, such as cows, dogs, or farm animals.
  •  Pathogens or parasites such as insects and small animals, which are responsible for decomposing the organic material such as the excrement from the cows.

By the other hand, the abiotic factors present in this area were:

  • The temperature, which was the same in every part of the field. As said before, it had sunny, dry and windy days. Wet and cold nights.
  • Wind, and because we were on a place that was located in a high altitude, the wind was stronger and colder.
  • Fire, which maintain the heat for species at night.
  • Humidity was present, but this area was more a dry place rather than a humid one.
  • Rain. It only rained at night, making it colder.
  • Light intensity. Bright sunny days.

Another area we were present was the forest were the river went by. The biotic factors for this area were:

  • Vegetation. Here, the vegetation varies, as there is an increase on plant and animals species. Here the soil has very different characteristics than the one where the cattle were, hence, different species grew. Here we could find a higher range of trees, flowers, bushes, and plant species.
  • Animals were founded but more insects, and arthropods.
  • Parasites, insects

The abiotic factors present were:

  • The river, in difference, from the plane area, here a river was found, and hence
  • Humidity, the humidity was higher at this place, but it not too much to notice the change on the air.
  • Rocks, many rocks that were product from the river were nearby.
  • Temperature, (the same as above)
  • Wind
  • Rain
  • Light intensity. Bright sunny in the day.

Finally, the last area that we visited was the mountains. Here the biotic factors changed a lot. We can see a difference not only because of the amount of vegetation but of species found on each area.  So the biotic factors were:

  • Vegetation. Had a huge variety of plant and animal species. The species that were found on the river were the ones that adapt better to those abiotic conditions. But here the species were so different and in a large quantity that it was easier to see bigger animals rather than only arthropods.
  • Animals. Animals here were very different as were the ones that adapted better to these conditions. There were found bigger animals, such as birds, or rats and obviously, arthropods, insects and small decomposers.
  • Parasites. Here the parasites and insects were found more than the other areas due to the higher range of plant species.

The abiotic factors were:

  • Temperature (same as the others)
  • Wind.( more wind due to altitude)
  • Humidity, no to much, the weather was more a dry weather than a humid one
  • Light intensity from the sun. Here sun rays were had more impact as the altitude allowed us to me near the sun rays.
  • Rain
