Studies on variation in interspecific hybrids of Saccharum

Sugar Tech, 2010
The extent and pattern of variation were studied in the seven crosses of F1 population of improved S. officinarum x Interspecific hybrids of Saccharum involving one cultivated S. barberi and two wild species S. spontaneum and S. robustum. The study revealed the superiority of all the crosses for cane population and presence of substantial variability ...

Absorption by the cecum of wild birds: Is there interspecific variation?

Journal of Experimental Zoology, 1989
The major functions proposed for the avian cecum--energy balance and osmoregulation--involve absorption of material from the cecum, yet little is known of these absorptive processes in wild birds. The magnitude of transport of compounds from the ceca depends on the concentrations of compounds in the ceca, the presence of transport pathways for those ...

Studies on variation in interspecific hybrids ofSaccharum

Sugar Tech, 2000
The extent and pattern of variation were studied in F1 population of improvedS. officinarum xS. spontaneum and commercial hybrids xS. spontaneum obtained from six crosses. The study revealed the superiority of all the crosses for cane population and presence of substantial variability for further effective selection and utilisation.

Interspecific variation in epicuticular waxes of Chionochloa

Phytochemistry, 1988
Abstract Interspecific variation in 19 species of Chionochloa was investigated by examining the major carbon chain lengths of fatty acids, alcohols, aldehydes, wax esters and alkanes of the epicuticular waxes. The chain lengths ranged from C24 to C32 in the acids, alcohol and aldehydes C21 to C33 in the alkanes and C34 to C52 in the wax esters.

A taximetric study of interspecific variation in Vitis

2017
A taximetric study, utilizing 71 plant characters for 21 species of Vitis has been completed. Phenetic similarities among the species were estimated by productmoment (r), distance (d) and divergence (D) coefficients. The unweighted pair-group method of clustering was used to graphically summarize the results in three phenograms.

Interspecific variation in leaf wax of Dudleya

Biochemical Systematics and Ecology, 1979
Abstract The distribution of the pentacylic triterpenoids, β-amyrin acetate and taraxerone, in the glaucous epicuticular wax of Dudleya subgenus Dudleya is correlated with both the geographic distribution and corolla tube length of a particular species. This is significant in a genus with many systematic problems.

Intra- and Interspecific Variation in Primate Gene Expression Patterns

Science, 2002
Although humans and their closest evolutionary relatives, the chimpanzees, are 98.7% identical in their genomic DNA sequences, they differ in many morphological, behavioral, and cognitive aspects. The underlying genetic basis of many of these differences may be altered gene expression.

Interspecific variation in products of animal mitochondrial protein synthesis

Nature, 1976
THE DNA of mammalian mitochondria (mtDNA) exists as a single class of circular molecules about 5 µm long1,2, and codes for two ribosomal RNA species and several transfer (4S) RNA components3,4. The function of the remaining 80% of the genome is unknown, although it has been suggested that the residual coding capacity provides messenger RNA (mRNA) which

Intra‐ and interspecific variation in macaque molar enamel thickness

American Journal of Physical Anthropology, 2014
ABSTRACTEnamel thickness has played an important role in studies of primate taxonomy, phylogeny, and functional morphology, although its variation among hominins is poorly understood. Macaques parallel hominins in their widespread geographic distribution, relative range of body sizes, and radiation during the last five million years.

Interspecific and environment-induced variation in hypoxia tolerance in sunfish

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2016
Hypoxia tolerance is a plastic trait, and can vary between species. We compared hypoxia tolerance (hypoxic loss of equilibrium, LOE, and critical O2 tension, Pcrit) and traits that dictate O2 transport and metabolism in pumpkinseed (Lepomis gibbosus), bluegill (L.
