Elements of natural and built environment project one(2)

  1. 1. INTRODUCTIONThis is our first project of Elements of Natural andBuilt Environment a.k.a ENBE.The main purpose of this project is to let us toexplore and know our nature before going for builtenvironment as we know that an area beforeconstruction is one part of the nature.As we known that basic is very important, beforeunderstanding the built environment, we learnabout how it was before first.
  2. 2. SITE VISIT : 15 – 16 APRIL, RIVERSTONE ECORESORT.The first part of our project starts by going for a site visit inRiverstone Eco Resort. It was a very natural place that allowsus to expose to the nature.There’s only electricity during 7pm-12am, no air-conditioner, water heater as well as internet.The place is surrounded by forest, river and lake and our taskhere is to search and choose a place with measurement of10m x 10m to do our researches for our project.This site visit allows us to see and to feel the nature byourselves instead of doing research all from the internet orbooks.Well, it was surely a interesting and exciting experience for uswho lives in city with all the technological equipments.
  3. 3. THE SITE VISIT :With the site visit brief that ourlecturers, Ms. Norma and Ms. Delliyaprepared for us, we are able to checkwhether we bring all the things neededand get well prepared before going tothe site .
  4. 4. We gathered in Taylor’s University at 7am and departedat 8:30am. The journey was by bus and we reached ataround 10am.Everyone did duringthe journey to the siteis having enough restbefore starting theproject ! :Arrived in theresort.
  5. 5. The Riverstone Eco Resort !!!After a short brief fromMs. D, we went toexplore around theresort search for a placefor our site .
  6. 6. Our dorm.Well it was quite dirty because thepillows and bed sheets were full ofdust but after they changed them itwe are satisfied with it.
  7. 7. SITE SELECTING.We went around the resort and finally we had chosen the stream asour site.Why? This is because we loved the environment here at the firstpoint, then we discovered there’s a quite variety of species that wecould research on here.The place we selected is where the water flows at a slowerspeed which allows us to do our research easier and safe.
  8. 8. IN OUR SITE : THE STREAM.It was a very enjoyful experience researching at the stream as theair condition here was quite humid and the mangrove treesacting as natural umbrellas which blocks most of the sunlight.The water was cold and clear that u could see under the sandsbeneath easily. The rocks that shows its head out of the waterwere natural chairs for us.With the fresh air with a lil bit salty smell, we felt relieved and sorefreshing that made our mind extraordinary concentrating.The sounds from the nature such as bird chirping, water flowing andleaves swirling in the wind made a soft music without any vocals.The land which is in dark brown and the sands in the water which islight brown makes us curious on what mades them different. Thebamboo with thin and straight stem and the mangrove tree withthick trunks with rough textures on it makes a bright difference intheir appearance although they both were plants.
  9. 9. In our site, I’ve tried the taste of the riverwater too, it taste likenormal mineral water to me but it was fresh compared tonormal ones.Besides, I’ve tasted the sands in the water too ! Well it tastes abit salty.The texture of the rock is rough except the area which grewmoss, has a slippery texture.
  10. 10. PICTURES : SITEPictures fromdifferentangle.
  11. 11. OUR FINDINGS : PLANTSRoots of mangrove treeMossAlgaeRhodes GrassFungus
  12. 12. OUR FINDINGS : ANIMAL / INSECTWater Strider ( itwas very sensitiveand moving veryfast so I couldn’tcapture a clearphoto of it :c )Some kind of prawnwith fur that we found .Mealybug.Leech ( wecouldn’t capturethe one we sawin our site butwe captured theone that bite oneof our coursemate.
  13. 13. RESEARCH: WATER STRIDER ( GERRIDAE )Sorry this is theclearest picture that Icaptured it :cThis is a spider like insect which lives onthe surface of water. They generally inhabitin freshwater area with calm water flow.They mostly lives in groups. When thesurrounding environment is unflavored tothem, they will fly to another area by usingthe small wings they had.Why did I choose this Insect to research on :Well the first time I saw this insect then I was caught by it. I’m prettycurious what it was actually. It looks like a spider but it did not behavelike a spider. Besides, It lives on water which is the main thing that Iwant to know bout : how it stay on water all the time?Well this is the main reason that brings me to the research on it .
  14. 14. Body of the Strider :How they look in close.AntennaeMiddle Legs :Use for paddling.Hind leg :Act as brakeand forsteering.Front legs :To catch prey.ThoraxAbdomenHeadSketched by myself.
  15. 15. DIET OF WATER STRIDER1. The front legs of water strider acts as sensors tofeel the vibration of water.2. When an insect fall onto the water surface andthen struggling, the water strider will be attractedby the vibration produced by the ripples in thewater.3. They go to the prey and grab onto the prey andthen puncture its body with its claws.4. Lastly they suck out the sustenance in a methodcalled suction feeding.
  16. 16. PREDATORS :As a insect living on the surface of river, waterstriders are hunted upon largely by birds, frogs andfishes but they are not the main food source forthem.Water strider’s front leg only able to detect vibrationsfrom the surface on water where made them unableto detect movements in the water and on the air.This made them unable to escape from gettinghunted by these animals.
  17. 17. MATING BEHAVIORSex recognization of water strider is determined by the ripplefrequency produced by the male strider. The male striderpredominantly produces 3 kind of communication frequencysignal which is 25 Hz as a repel signal, 10 Hz as a threatsignal, and 3 Hz as a courtship signalWhen a male strider approaches another strider, it will firstproduce a repel signal, if the another strider doesn’t reply withsignal, then it knows that it’s a female strider and changes intoa courtship signal.Then, the female strider will lower its abdomen and allow themale strider to mount and mate.
  18. 18. LIFE CYCLE ( MAIN THEME OF INFOGRAPHIC)Egg StageInstar Stage( 5 times )Adult StageApproximately 60-70daysLarval Stage.Takes around10-15days untilinstar stage.The development stages is highly correlated to thesurrounding temperature where the egg was.Eachinstarstagetakesaround 7-10days.
  19. 19. Water striders are insects that skate around on the surface ofwater. The life cycle of water striders begins when an adultfemale lays eggs, generally on rocks or aquatic vegetation.When the eggs hatch, they enter into a nymph stage in whichthey look much like an adult but only smaller. The final stageof a water strider is when they are capable of reproducingafter entering their adult phase. Some other insects that sharea similar life cycle as that of water striders include box elderbugs and grasshoppers.
  20. 20. RESEARCH : RHODES GRASSWe had a smaller bunch of rhodes grass in our site but it wasnot clear to be seen, so I decided to use the picture of a bigbunch of rhodes grass near our site.
  21. 21. RHODES GRASS :Why did I choose to rhodes grass to researchon?This is because rhodes grass is a very common plantthat we can see it everywhere but we don’t reallyknow what does it called and what it is.So, I decided to research on it.
  22. 22. INFO’S : RHODES GRASS Has a scientific name of Chloris gayana Kunth. An erect almost hairless, stoloniferous or tufted, summergrowing perennial grass 0.5 to 1.2 m tall. Stems: Smooth and shiny; creeping stems 4 - 5mmdiameter, and upright stems 2 - 4mm diameter. Leaves: Leaf blades are hairless except at the basenear the stem and usually of the order of 30 - 40cm longand 3 - 5mm wide, tapering to a point. Seedhead: Mostly a single (sometimes double) circleof radiating light, greenish brown (ripening to darkerbrown) branches 4 - 15cm long. Seeds: Light and fluffy, 3.5 mm long, each bearing along or short awn; 4 million or 7 - 10 millionseeds/kg. Seeds contain a small dark brown grain, with2 million caryopses/kg.
  23. 23. LIFE CYCLE : RHODES GRASS Rhodes grass is a tropical grass, growing over thefrost-free months and flowering in summer andautumn. It can grow prolifically following summerrains. It can be perennial or occasionally annual. Seed germinates 1-7 days after planting or inSpring and it grows rapidly over summer. Stolons may form in the first and subsequentsummers to spread the plant.In our country Malaysia which has a tropical rainforestclimate, it can grow free without stopping due to the lack ofother unflavored seasons such as spring, autumn andwinter where Malaysia is summer all the time.
  24. 24. HABITATThey prefers open sunny situations, openwoodlands, grasslands, river and lake margins, seasonallywaterlogged areas.SOILPrefers red earths and loams but grows on a widerange of soils from clays through to sands.TEXTURESmooth surface on the leaves.The side of leave blade is quite sharp that could cut awound on hand.Rough surface on the root and stolon stem.
  25. 25. ROOTS : It has fibrous roots. Well developed deep root system. Roots to 4.7 m deep but few roots extend beyond2.4 m.Due to its high survivability it is one of the pioneerspecies that changes the quality of the soil until itbecome more favorable to other species of plants.
  26. 26. 16 ARPIL 1PMBefore leaving the resort, we took a group photo of allof us !
  27. 27. REFLECTIONS :At first what I was thinking before going to the site was just enjoyand have fun! But after reaching the site, checked-in our dormand saw the dirtiness and the daily things we used to have ismissing, but then when i think rationally, it was right, I came forlearning not enjoying life ! Then I stopped complaining about thedorm.In our site, I found that how clear a river was, how peaceful annatural habitat could be. I started thinking why are we destroyingour nature? It was the best gift for us ! Unfortunately we humanskept doing things to ruin it ! I realised that I should do more tohelp our nature, at least not causing anymore pollutions to ournature !The creatures in the ecosystem is all linked to each other, a changein one of the population could make a big change to all otherpopulation related to it ! Example, an great increase in amount ofmealy bug might cause the many of the mangrove trees in thearea died because that mealy bug is the pest of it! So, we shouldconserve our ecosystem to prevent the extinction of wildlife tomaintain the balance of ecosystem .
  28. 28. INFOGRAPHIC POSTERAfter the researches, we combined all our findingsand made it into an infographic poster with a themeof Life Cycle.
