The phrase "a source of morphological" is correct and usable in written English.
It can be used in contexts discussing linguistics, biology, or any field where morphology is relevant, indicating an origin or provider of morphological features or data.
Example: "The study identified a source of morphological variation in the species, shedding light on its evolutionary adaptations."
Alternatives: "an origin of morphological" or "a provider of morphological".
The description of L. terrestris by Sims [8] serves as a source of morphological details.
These results highlight the importance of hybridization as a source of morphological variation, diversity and evolutionary novelty.
MicroRNAs, based on their presence in bilaterians and their ability to regulate development, are considered to be accountable for morphological complexity as well as being a source of morphological innovations (Peterson et al. 2009).
The convergence of disparate systems on equivalent metric values (mechanical equivalence) has been highlighted as a source of potential morphological diversity under the assumption that morphology can evolve with minimal impact on function.
Modularity emerges as a source of novel morphological variation by its simple potential to combine different parts of the parental phenotypes into a novel offspring mosaic of modules.
Differences between true wild and captive wild boar highlight the influence of captivity as a primary source of morphological change, which may reflect those that occurred during the initial stages of domestication.
Basically, some have argued that noncoding cis-regulatory mutations are a primary source of morphological novelty because regulatory change is thought to be more likely to have spatially or temporally restricted effects than protein sequence change (Stern 2000, Carroll 2005).
On the other hand, many carnivoran species use their forelimbs for activities other than the ones involved in locomotion, such as grasping, climbing, or manipulating prey [ 28, 33, 43] and this could also be a potential source of morphological differences between the fore- and hind limbs.
In mouse-to-elephant comparisons, size differences could represent the largest source of morphological variation, and isometric scaling factors such as Fr can compensate for much of the variability.
SARPs have also been proposed as a source of genetic variation for rapidly evolving morphological traits [ 17, 18].
Based on our observations we suggest correcting for these types of morphological parameters, which may be a source of noise when used in predictions of cellular ostogenic potential.
