"However, this study suggests that vertical climbing and arboreality
were not significant parts of their locomotor repertoire."
An engineering analysis of Archaeopteryx's reversed first toe (or 'hallux') seems to clinch the case for arboreality
, for this fully opposable digit is ideally suited to grasping branches, and is present in all modern perching birds from warblers to ravens.
torquatus has a larger degree of arboreality
, being found on bromeliad and tree trunks (Bergallo and Rocha, 1994).
Increased levels of stress caused by time spent in direct contact with humans, reduced arboreality
, and lack of a nutritious and normal diet may contribute to increased levels of infection (4).
The pattern and degree of divergence may also depend on other ecological characteristics, such as the degree of arboreality
, and taxa may respond to the river barrier, including its associated seasonally flooded margins, in different ways.
