BiologieThema 6: Biodiversiteit en duurzame
ontwikkeling
Biodiversiteit: 3 niveaus
1) Op soortniveau: optelsom alle soorten in bepaald gebied
- Monoculturen nadelig weinig biodiversiteit want beperkte
levensgemeenschap
beperkte aantrekking planeteneters / predators + weinig variatie
voedselkeuze / nestgelegenheid / bescherming
- Chemische bestrijdingsmiddelen
gebruik van pesticiden / herbiciden / fungiciden
tast andere planten / insecten aan buiten de zone
vergiftigde prooidieren en kan zelfs effect hebben op toppredators
2) Op genetisch niveau: optelsom verschillen tussen genen
- Erfelijke kenmerken worden doorgegeven via DNA; genetische
diversiteit (= verscheidenheid aan genen binnen elke soort)
- Meer genetische diversiteit (bv. planten / huisdieren) gewenste
eigenschappen doorgeven + verbeteren
Belang genetische verscheidenheid?
- Motor van biodiversiteit
- Grote genetische biodiversiteit beter aanpassen
- Weinig genetische biodiversiteit kwetsbaar voor plagen
3) Op niveau van ecosystemen: optelsom ecosystemen
