Such importance is underlined by the fact that evolutionary studies enable future conservation plans to take into consideration their findings (Heywood et at ). Consequently, there is a view in contemporary biology that, other than preserving species and ecosystems. The Notre Dame Institute for Advanced Study (NDIAS) supports research that is directed toward, or extends inquiry to include, ultimate questions and questions of value, especially as they engage the Catholic intellectual tradition.

Dalam biologi, genus (jamak genera) atau marga adalah salah satu bentuk pengelompokan dalam klasifikasi makhluk hidup yang secara hierarki tingkatnya di atas spesies, tetapi lebih rendah daripada sistem tata nama binomial, nama suatu spesies makhluk hidup terdiri atas dua kata, yaitu nama genusnya (diawali dengan huruf kapital) dan nama penunjuk spesiesnya dengan ditulis atau. Seed morphology of 29 taxa including 9 subgenera belonging to the genus Veronica was compared using scanning electron microscopy to assess their diagnostic value for systematic studies. Subgenus Beccabunga is the largest in this study represented by nine taxa. Seed surface often varies from ridged reticulate or verrucose/granulate reticulate to rugose‐reticulate. A revision of the genus Capparis has been carried out in New Caledonia, a global biodiversity hotspot with a high rate of endemism in its vascular flora. The taxonomic treatment of Capparis in this area required study because of some incompletely known taxa and deviating forms. Based on morphological and distributional investigations carried out on historical and recent herbarium collections.

Description: GENUS is an online and print peer-reviewed Journal of Population Sciences published by the University of Rome “La Sapienza” with the support of the Department of Statistical has adopted an interdisciplinary approach to population studies. It publishes articles of “pure” demography and articles aiming to further a better knowledge of the interrelationship. The Genus Meconopsis is the first major revision of the genus since and the only monograph on the genus in existence. This fully revised text incorporates the discovery of nearly thirty new species with decades of new scholarship. The book is extensively illustrated with striking color photographs and botanical paintings.   The plant genus Erythroxylum encompasses over species and has been cultivated and used by South American communities for thousands of years. E. coca is included as one of the oldest cultivated. Bees play an important and necessary role in the pollination of agricultural crops grown for fruit and seed and of forage and browse plants important in range management for production of both livestock and game animals. Nea different kinds of bees are now known, some, like the imported honey bee, the bumble bees, and the stingless bees of the tropics, are social and live together in.

The family Cannabaceae now includes Cannabis, Humulus, and eight genera formerly in the ng Cannabis, Humulus, and Celtis actually goes back years. Print fossil of the extinct genus Dorofeevia (=Humularia) reveals that Cannabis lost a sibling perhaps 20 million years.

The genus of a connected, orientable surface is an integer representing the maximum number of cuttings along non-intersecting closed simple curves without rendering the resultant manifold disconnected. It is equal to the number of handles on it.

Alternatively, it can be defined in terms of the Euler characteristic χ, via the relationship χ = 2 − 2g for closed surfaces, where g is the genus. The Cape Floristic Region is the most diverse of the Mediterranean climate floras.

Cliffortia (Rosaceae) is one of the ten largest genera within the Cape Flora with species currently recognised, of which are endemic to the region. So if genus refers to any kind of thing, then primates, bovines and animals are all genus. In that case, oxes and humans share the genus animal but do not share the genus primate or bovine.

Perhaps Aristotle means to claim that the most specific genus possible must be shared in order to say that they have the same genus. Systematics of the genus Cliffortia L. [Rosaceae] Introgression is interesting for plant evolutionary studies because it yields significant numbers of new genotypes, thus increasing genetic.

The present studies based on field observations and on the materials deposited in CAL and ASSAM clearly show that the genus is represented in India by 10 species.

Materials and methods A large number of specimens from all over India and abroad (in CAL and ASSAM) have b› examined. 1 Introduction. The genus Elymus L.

(Triticeae, Poaceae) is a wild relative of several economically important grasses (e.g., wheat, barley, and rye) and may be therefore a valuable genetic resource for improving grain crops.

Moreover, many species of the genus have long been investigated as model organisms in studies on reticulate evolution, genome dynamics, and chromosome organization.

The genus level classifications are very valuable when the fossil studies are concerned, as the details of understanding the organisms up to species is not always possible. Two organisms from one genus might or might not produce an offspring with sexual fertility, but it is very certain that organisms from two different genera (plural of genus.

The genus Heliopsis is a member of the tribe Heliantheae of the family Compositae. It is represented by thirteen species, all of which are restricted to the western hemisphere. Although some of the species, particularly those of the United States, have received attention recently, there has been a great deal of.
