Natural selection drives micro-evolutionary changes.
Most studies focus on morphology rather than traits of the entire organism.
Ecological context also needs to be considered.
Morphology influences locomotor performance in organisms such as running, swimming, or flying.
It is usually single traits that are studied rather than multiple traits and their complex interactions leaving a gap in the research that has been done.
Different traits allow for niche partitioning when habitat is shared by lizards with different morphologies
Caribbean Anolis have been the subject of many morphology studies
Lizards were captured on an island
Perch size/diameter were recorded to use in the study as a baseline
Hind limb length was measured. Standards for the recording were established, a caliper was used, and all measurements were taken by the same individual to avoid errors in the data collection.
Lizards were tagged using injections of colored elastomer dye in specific color combination for easy continued identification over the span of the experiment.
Does morphology, performance, and habitat interact to influence fitness?
Anoles with longer limbs preferred broader perches
Anoles with shorter limbs preferred narrower perches
Sprint sensitivity; faster on brad surfaces (10 cm) and slower on narrow surfaces (2.5 cm)
Sprint sensitivity: slower on broad surfaces (10 cm) and faster or no decline in speed on narrow surfaces (2.5 cm)
Their research showed that there was a significant difference exhibited in the experiment.
Questions???
If morphology of the "entire organism is supposedly important than why wasn't reproductive preferences included in causes for morphology
Does habitat influence the natural selection of the morphhology or does the morphology influence the type of habitat chosen by the anoles? Could the niche chosen be personal preference for the lizards?
