We used two different methods to quantify variation, which are based on different measures of morphological distance: Procrustes distance and Mahalanobis distance [27].
Microalgae are classified in groups based on different characteristics, with huge morphological variations such as round, oval, cylindrical, and fusiform cells, as well as projections like thorns, cilia, etc.
These results suggest that cartilage defects in Hoxc8- or Hoxd4-transgenic mice, while similar at the morphological level, may be based on different molecular mechanisms.
In this article, we attempt to classify hepatic lymphomas based on the different morphological patterns seen on imaging at presentation and discuss the various other more common hepatic lesions that need to be differentiated from lymphoma.
However, the estimated K-scores indicated that the three distance-optimized trees based on the different morphological datasets were almost congruent in topology and branch lengths, implying similar changes on nodes between the trees.
Selection of different foci was based on differences of histological and morphological phenotypes and was performed and controlled on the basis of HE stainings and P63/AMACR double immunostainings.
Samples were selected based on morphological differences and collected from different regions with a range of ecological and altitudinal variations.
Based on subtle morphological differences, Minckley (1969, 1971) redescribed the two taxa as different subspecies, P. o. occidentalis (Gila topminnow) and P. o. sonoriensis (Yaqui topminnow).
According to Galluzzi et al. [ 44], cell death can be classified into four different types based on the morphological characteristics of the dying cells: apoptosis (Type 1), autophagy (Type 2), necrosis (oncosis, Type 3), and mitotic catastrophe.
