ISTITUTO COMPRENSIVO “L. DA VINCI”

Via Togliatti – 73020 Cavallino (Lecce)

  • OUR WORK METHOD

  • We have chosen following site to conduct our study

ANA LYSIS OF THE PROBLEM:

Study the biodiversitythrough the color of the flowers in differentenviroments to human disturbance.

We can use different colors or shapes of the corollis to menasure the biodiversity.

NULL HYPOTHESIS:

In enviroments more frequented or lessfrequentedthere are the sameflowers

The meadowaround the gym

The flowerbeddividing the road

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 photos

OUR RESULTES

BIO-DIFFERENT… MEADOWS!

During 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.

BIODIVERSITY IS… LIKE A PATCHWORK!

The hedge

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 hypothesis

The meadow around the gym

A meadow in the countryside

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
