The tasks of categorization and category learning, for example, can be significantly simplified by exploiting the morphological constraints, sensory motor couplings and the interaction with the environment.
Due to genitalic morphological constraints between the two species, introgression is likely to be unidirectional with female L. sinapis potentially inseminated by male L. reali [ 36, 44].
Of course, in general there will be metabolic, bandwidth or morphological constraints, which can be readily incorporated in the constraints on sensor and actuator evolution.
Morphological constraints on the supply of oxygen, such as the structure of the lung, have previously been studied in birds.
The behavioral implications of these morphological constraints may be relevant to the use of active electro-orientation/navigation [20], [25], [27] among different species.
We argue that allodapine sociality has been maintained by ecological constraints and the benefits of alloparental care, as opposed to behavioural, genetic or morphological constraints to independent living.
Laternula species are conservative in shell form and habitat suggesting they share morphological constraints at different latitudes [ 32].
Such morphological constraints might also have led this group to further specialization of the scale eating habit.
Rhizomatous perennials with cylindrical leafless culms (common in genera such as Eleocharis, Juncus and Schoenoplectus), broad-leaved species such as Typha spp. and narrower-leaved genera such as Carex that may be variously tussock- or sward-forming have different morphological constraints controlling their depth responses, and hence may be difficult to compare directly in growth experiments.
