• Defined biodiversity, species, and the types of diversity
(ecosystem/community/habitat, genetic and species)
• Biodiversity conservation requires a firm understanding of
• where species and populations occur,
• species interactions with other species and the environment
• Measures of species diversity (Alpha, Gamma, Beta- self study)
• Habitat loss and fragmentation
• Drivers of habitat loss and fragmentation (self study)
,
,Habitat loss’ impact on Africa’s ecosystems
, • Loss and fragmentation impact most of the earth’s major biomes
from tropical and temperate forests to grasslands and from
wetlands to rivers
• Quantifying the extent of this loss and fragmentation is difficult
• One major problem is determining what vegetation existed
historically to establish a benchmark for comparisons
• Another issue is determining the extent that change is caused by
humans versus natural forces
