Intra-varietal morphological variation in harumanis cultivar 109 despite its appealing qualities, harumanis is facing a problem which related to the production inconsistency due to phenotype variation which caused the flesh colour and sizes of the fruits to be varied although they are harvested from the same cultivation area.
Most of this variation is highly systematic: speakers of a language make choices in pronunciation, morphology, word choice, and grammar depending on a number of non-linguistic factors. These factors include the speaker's purpose in communication the relationship between speaker and hearer, the production circumstances, and various demographic.

In older, unlogged rainforest of hainan island, china, leaves of saplings were larger, and fine root systems of saplings were thicker with fewer root tips than in historically logged areas. These results were consistent among 15 angiosperm lineages, even though families differed widely in their leaf and root traits. How plant organ morphologies vary with environment is key for inferring plant.
The morphological variability of freshwater bivalve species, observed between and within river basins, may hamper their correct identification, even by experienced researchers. Shell length, height and thickness, or their ratios, are generally insufficient to distinguish populations and/or species.
1 u6 continuous variation across the geographical range of related populations matches the concept of gradual divergence.
Studies of morphometric variation make it possible to delimit species and geographic intraspecific variation, mainly in species with wide distribution ranges.
The single arterial valve found in hearts with common arterial trunk (cat) is known to show great morphological variability, with different numbers of leaflets and presenting frequently as dysplastic and insufficient or, more rarely, stenotic.
Variation in morphological processesvariation in all its facets affects morphological units and morphological processes, even the most productive ones such as inflection. Variation in derivationit is often the case that for creating words of a specific category, a derivational process may exploit more than one form of a particular unit.
Assessment of agro-morphological variability of dry-season sorghum cultivars in chad as novel sources of drought tolerance.
The five factors that can drive evolution mutation non-random mating migration into or out of the population small population size (leads to genetic drift).
Conversely, this morphological variation may have a genetic basis and be favored by the self-incompatible sex-ual reproduction system, which, along with vegetative propagation, is characteristic of this species (casas, 1997). Nevertheless, the variation in fruits could be also the result of manipulation of this.
The coefficient of variation (cv) and the principal component analysis (pca) are used to assess the variability among tree populations.
Morphological plasticity according to environmental variability is commonly found among many fish species, predominantly in freshwater fish species. Phenotypic variation according to environmental variability has been widely used by ichthyologists to differentiate among species and among populations.
We examined morphological variability and evolution of the baculum (os penis) across the mustelidae through allometric analyses and character mapping. Fifty-four species and 26 genera (including 2 fossil forms) were examined with numerous caniform out-group species.
The process applies in a few different morphological contexts. Ideally, the process applies to a few different morphological exponents. It would also be nice to know if the rate of variation is affected by the morphological structure it applies in/to.

It is well known that l2 learners exhibit optionality or variability in their use of verbal and nominal inflection and associated lexical items.
Pollen morphological diversity is mainly attributed to abiotic factors such as air temperature that influence both size and shape of pollen grain, giving it the ability to fold back on itself to decrease dehydration. Other factors such as animal pollinators and altitude also play a role in pollen morphological variability.

The most frequent morphology, and most clinically useful, was the medium-sized lobe with free-arched contour and eminent or cross-continuous modeling.
1 morphological variation morphology is the area of linguistics concerned with the internal structure of words. It is usually broken down to two types, inflectional and derivational.

In this paper, i investigate the phenomenon of morphological variability in the production of italian determiners, descriptive adjectives, and direct object pronouns by adult english learners of italian to determine whether morphological errors are the result of computational or representational difficulties.
The results indicate that the magnitude of size variation within chitinozoan species is larger than observed in fossil and modern eggs. Additionally, delicate morphological structures of chitinozoans, such as prosome and complex ornamentation, are inconsistent with the egg hypothesis.
Branches of and approaches to morphology the two branches of morphology include the study of the breaking apart (the analytic side) and the reassembling (the synthetic side) of words; to wit, inflectional morphology concerns the breaking apart of words into their parts, such as how suffixes make different verb forms.
Mar 22, 2019 most species of algae are single-celled micro-organisms living in aquatic environments.
The morphological variability of freshwater bivalve species, observed between and within river basins, may hamper their correct.
Morphometrics can be used to quantify a trait of evolutionary significance, and by detecting changes in the shape, deduce something of their ontogeny, function or evolutionary relationships. A major objective of morphometrics is to statistically test hypotheses about the factors that affect shape.
Morphological variability of the shape of striped red mullet mullus surmuletus in relation to stock discrimination between the bay of biscay and the eastern english channel.
Darwin's finches are a classic example of species diversification by natural selection. Their impressive variation in beak morphology is associated with the exploitation of a variety of ecological niches, but its developmental basis is unknown. We performed a comparative analysis of expression patterns of various growth factors in species comprising the genus geospiza.
For instance, in the figure below, branches that don't reach the top of the diagram represent extinct species (or taxa).
Objective until now, no study established a morphometric evaluation of the truncal valve dysplasia and a description of its different presentation patterns. Thus, authors conducted an anatomopathological study describing the gross features and histological findings of the truncal valve. Methods 50 common arterial trunk (cat) specimens were examined.
However, to our knowledge, no study has addressed this question directly. The aim of the present work was to compare the morpho-logical plastic responses of two perennial aquatic plant species, berula erecta (apiaceae) and mentha aquatica (lamiaceae), that co-occur along the same gradient of increasing.
We examined sources of morphological variability in second language (l2) learners of spanish whose native language (l1) is english, with a focus on l1-l2.
