    OUR WORK METHOD

    We have chosen following site to conduct our study

    . A meadow in the countryside The meadow around the gym

    ANA LYSIS OF THE PROBLEM:

    Study the biodiversity through the color of the flowers in different enviroments to human disturbance.We can use different colors or shapes of the corollis to menasure the biodiversity.

    NULL HYPOTHESIS:

    In enviroments more frequented or less frequented there are the same flowersISTITUTO COMPRENSIVO L. DA VINCIVia Togliatti 73020 Cavallino (Lecce)RESEARCH GAME We have decided to visit the three areas three times in four different weeks during the month of march.Every time we have used two samples of 2 m2 for each areas.During each sample we have observed the different flowers, written notes and observations and taken photosOUR RESULTES

    OUR CONCLUSIONS

    We can observe that in site n 3 the species are more than in the other sites. So we can say that , in the areas we have studied, biodiversity is not the same; this fact, probably, depends on different anthropic trouble.

    Therefore we can reject the null hypothesisBIO-DIFFERENT MEADOWS!

    BIODIVERSITY IS LIKE A PATCHWORK!The flowerbed dividing the roadThe hedgeThe meadow around the gymA meadow in the countrysideDuring our sampling, we have observed that some flowers are more common; we have found them in all areas. On the contrary, other flowers are specific of one area.For example, latte di gallina grows only in the meadow in the contryside, while the tarassaco is present in all areas.

    So we can recognise GENERALIST species, that live in each area, and SPECIALIST species that live only in one area.Giorgio Armillis Carla Gigante Nicola Lezzi Davide Olibardi - Alessio Pizzolante - Noemi Spera Mariaandrea Scardino Sara Totaro Aprile We can represent the biodiversity in the areas we have studied with a patchwork. It has a rectangular shape whose sides are 1 meter per 2 meters. We have subdivided it into 24 squares and in each of them we have put one of the species we have found

    SITE CHARACTERISTICN.1 : The hedge that divides the road in front of the school. The area is sunny There are trees (pinus) The ground is hard, compact and reddish High anthropic trouble : car traffic; school students.

    N.2 : The meadow around the gym outside of school. The area is sunny. The ground is reddish-brown. Threre is a fencing wall. There are cultivated plants. Middle anthropic trouble: students who use the sports field.

    N.3 : A meadow in the countryside away from roads and houses. The area is sunny. The ground is soft and reddish-brown. There are little olive trees. There arent fences. It is little frequented by people. Low anthropic trouble.
