Pollen Analysis

Pollen Analysis. Correlate Quaternary stratigraphic units. Reconstruct vegetation history. To investigate the impact of human activities on late Quaternary vegetation and landscape in many parts of the world. Pollen Analysis. Pollen Characteristics. Resistant to decay .

Habitat Fragmentation

Habitat Fragmentation. Sometimes habitat is not lost nor converted, it is simply fragmented Fragmentation has 2 components: 1) a reduction in the area covered by a habitat type 2) a change in habitat configuration, with the remaining habitat apportioned into smaller and more isolated patches.

Community Assembly

Community Assembly. A pervasive theme in community ecology is that the species composition of a community is governed by deterministic “assembly rules” Typically these rules emphasize the importance of interspecific interactions (e.g. niche overlap, body size distributions). Community Assembly.

Speciation

Speciation. More about change over time…. Adaptations. All organisms have adaptations that help them survive and thrive. Some adaptations are structural.
