Photo: J. * Priority habitat Seffer. Summary Species-rich Nardus grasslands are some of the most widespread habitats in the EU, occurring in 24 Member States and 6 different bioregions. They include a huge variety of sub-types, which may be found in very different ecological situations. It is generally an oligotrophic habitat, typical found mostly on species-poor soils throughout Europe. In spite of the fact that some types of Nardus grasslands can be considered as climax vegetation which do not require active ongoing management, the long-term existence of the habitat is in general closely with pastoral traditions and with extensive agriculture. The area of the habitat in Europe has declined in the last decades because of the intensification of agricultural practices on the one hand and land abandonment and too low an intensity of the use on the other. Mountain types are also threatened by tourism and skiing activities. Grazing and mowing are the most frequent recommendations for the management of the habitat. ‘Appropriateness’ as regards grazing intensity and organisation varies considerably in different European regions and countries. The habitat in general requires extensive grazing which prevents invasion by trees and scrub, but which is not so intensive as to cause the eutrophication of the habitat. Mowing is also feasible technique which is applied mostly

Donoghue, Yale University, New Haven, CT, and approved December 31, 2009 (received for review August 24, 2009) Grasslands cover more than 20% of the Earth's terrestrial surface, has provided a strong selection pressure for C4 evolution in and their rise to dominance is one of the most dramatic events of eudicots (4). Grasses have long been viewed as an interesting biome evolution in Earth history. Grasses possess two main photo- exception to this pattern (9). Significant positive correlations synthetic pathways: the C3 pathway that is typical of most plants between C4 grass abundance and growing season temperature and a specialized C4 pathway that minimizes photorespiration and have been documented at both continental and regional scales thus increases photosynthetic performance in high-temperature (10–13); C4 grasses dominate tropical grasslands and savannas and/or low-CO2 environments. C4 grasses dominate tropical and but are virtually absent from cool-temperate grasslands and subtropical grasslands and savannas, and C3 grasses dominate the steppes. Furthermore, both experimental measurements of world's cooler temperate grassland regions. This striking pattern photosynthetic light use efficiency (termed “quantum yield”), has been attributed to C4 physiology, with the implication that the and predictions of leaf models of C3 and C4 photosynthesis evolution of the pathway enabled C4 grasses to persist in warmer provide strong evidence that C4 grasses outperform C3 grasses at climates than their C3 relatives.

  • Hilu Paper (New)
    KEW BULLETIN 62: 355–373 (2007) 355 A century of progress in grass systematics Khidir W. Hilu1 Summary. This paper presents an overview of progress in grass systematics with a focus on the past century and assesses its current status and future outlook. In concert with systematic biology, progress in grass systematics has gone through some leaps caused by the introduction of new approaches or emphasis on existing ones. Chromosome cytology, anatomy and chemistry provided useful information, but major recent contributions have come from advances in bioinformatics and molecular biology. Consequently, grass systematics has moved from an initial intuitive classification and phylogenetics to one incorporating analytical phenetic approaches, and culminating in the current stage of analytic phylogeny. As a result, a refined picture of grass phylogeny is emerging with good resolution at the base, but the tree lacks robustness in some places such as the monophyly of the “BEP” subfamilies and the relationships within the PACCAD clade. Systematic structure of a number of subfamilies is better understood now, but further studies are needed. With the rapid advancement in molecular systematic and bioinformatic tools, and in conjunction with a wealth of literature available on structural characters, a more refined picture of grass taxonomy and evolution is expected. However, caution needs to be exercised in our interpretations to avoid hasty decisions that can translate into regress rather than progress. This is an exciting time in the history of grass systematics and, undoubtedly, is a period of collaborative rather than individual effort. Key words. Poaceae, grasses, systematics, phylogenetics, history, evolution. Introduction valuable resources used in furthering our Although the c.

Introduction The genus Cymbopogon belongs to the tribe Andropogoneae of the subfamily Panir and ir is represented by 24 species in the Indian sub-continent (Bor 1960). A number of species of Cymbopogon yie•d essential oils and are used in perfumery. The embryoIogy of C. martinii and C. nervatus has been worked out by Brown and Emery (1958) although of a preliminary nature. The present paper deals' with the embryology of Cymbopogon nardus (L.) Rendle var. Confertiflorus (Steud.) Stapf ex Bor, C. martinii (Roxb.) Wats var. Motia and C. parkeri Stapf, to find the nature of seed sterility observed in differcnt specics. 2.
