Features and Conservation of the Brazilian Pantanal Wetland
Wetlands Ecology and Management 12: 547–552, 2004. 547 # 2004 Kluwer Academic Publishers. Printed in the Netherlands. Features and conservation of the Brazilian Pantanal wetland Arnildo Pott* and Vali Joana Pott Embrapa, Caixa postal 154, Campo Grande, MS, 79002-970 Brazil; *Author for correspondence (e-mail: [email protected]) Accepted in revised form 18 July 2003 Key words: Aquatic vegetation, Ecology, Floodable grassland, Neotropical wetland, Savanna, Vegetation dynamics Abstract The Pantanal is a 140,000 km2 sedimentary floodplain in western Brazil and one of the largest wetlands in the world. The main landscapes and phytophysiognomies, according to flood origin, are briefly described and some of the characteristic plant species are mentioned: (a) river flood (1–5 m) on clayey eutrophic soils with gallery forests, pioneer forests and scrub, Tabebuia and Copernicia parks, seasonal swamps, grasslands and oxbow lakes; and (b) rain flood (10–80 cm) mainly on dystrophic sandy soils (72% of the total area) with savanna (‘‘cerrado’’) grasslands and woodlands, with or without ponds. Regulating factors of the vegetation such as wet-and-dry cycle and management are considered. Dynamics of the vegetation, in particular the aquatic types, are shortly depicted. The role of grazing for conservation is discussed, and we suggest that 200 years of cattle ranching apparently did not cause major changes in the vegetation, except turning tall grass into short swards, as the domestic herd found a nearly empty niche. However, severe threats to the flora and fauna of the Pantanal originate outside the floodplain. Siltation of the Taquari river is pointed out as the worst environmental problem, changing the hydrology (wet-and-dry to wet), fauna and flora, e.g. -
CATALOGUE of the GRASSES of CUBA by A. S. Hitchcock
CATALOGUE OF THE GRASSES OF CUBA By A. S. Hitchcock. INTRODUCTION. The following list of Cuban grasses is based primarily upon the collections at the Estaci6n Central Agron6mica de Cuba, situated at Santiago de las Vegas, a suburb of Habana. The herbarium includes the collections made by the members of the staff, particularly Mr. C. F. Baker, formerly head of the department of botany, and also the Sauvalle Herbarium deposited by the Habana Academy of Sciences, These specimens were examined by the writer during a short stay upon the island in the spring of 1906, and were later kindly loaned by the station authorities for a more critical study at Washington. The Sauvalle Herbarium contains a fairly complete set of the grasses col- lected by Charles Wright, the most important collection thus far obtained from Cuba. In addition to the collections at the Cuba Experiment Station, the National Herbarium furnished important material for study, including collections made by A. H. Curtiss, W. Palmer and J. H. Riley, A. Taylor (from the Isle of Pines), S. M. Tracy, Brother Leon (De la Salle College, Habana), and the writer. The earlier collections of Wright were sent to Grisebach for study. These were reported upon by Grisebach in his work entitled "Cata- logus Plant arum Cubensium," published in 1866, though preliminary reports appeared earlier in the two parts of Plantae Wrightianae. * During the spring of 1907 I had the opportunity of examining the grasses in the herbarium of Grisebach in Gottingen.6 In the present article I have, with few exceptions, accounted for the grasses listed by Grisebach in his catalogue of Cuban plants, and have appended a list of these with references to the pages in the body of this article upon which the species are considered. -

Introduction in the Americas, Agreat Diversity of Bamboo Endemic Species Is Found in Brazil, North and Central Andes, Mexico and Central America
Theme: Environment: Ecology and Environmental Concerns Mexican national living bamboo collection ex situ conservation Ma. Teresa Mejia-Saulés and Rogelio Macías Ordóñez Instituto de Ecología A.C. Carretera antigua a Coatepec 351, El Haya, Xalapa, Ver. 91070 México. email: [email protected]@inecol.mx In the Americas, the highest bamboo diversity and endemism is found in Brazil, the northern and central Andes, Mexico and Central America. In 2003, there were 40 native species of bamboos described for Mexico in eleven bamboo genera. Recent work has brought this number to 56 species. More than the half (34) of the Mexican bamboo species are endemic. The Mexican bamboos grow in tropical dry and perennial forests, mixed pine-oak and pine-fire forests, pine forests, and cloud forests from sea level to 3,000 m elevation. Genera of described Mexican woody bamboos species (and spp number) are: Arthrostylidium(1), Aulonemia(1),Chusquea(22),Guadua(7),Merostachys (1),Olmeca(5),Otatea(11),Rhipidocladum(4). Herbaceous genera are Cryptochloa(1),Lithachne(1),Olyra(2). Many of them have a diversity of rustic uses such as material for roofs or walls, furniture, fences, baskets, walking sticks, handcrafts, beehives, agricultural tools as well as ornamental plants. Live collections at the Botanical Gardens that preserve plant genetic resources are curated for various purposes including scientific education and research. The Francisco Javier Clavijero Botanical Garden at the Instituto de Ecología, in Xalapa, Mexico, houses the Mexican national living bamboo collection. It was stablished in 2003 with the collaborative support of INECOL, Bamboo of the Americas, and the InstitutoTecnológico de Chetumal for the ex situ conservation of Mexican bamboo diversity, research and education. -

Morphological, Anatomical, and Taxonomic Studies in Anomochloa and Streptochaeta (Poaceae: Bambusoideae)
SMITHSONIAN CONTRIBUTIONS TO BOTANY NUMBER 68 Morphological, Anatomical, and Taxonomic Studies in Anomochloa and Streptochaeta (Poaceae: Bambusoideae) Emmet J. Judziewicz and Thomas R. Soderstrom SMITHSONIAN INSTITUTION PRESS Washington, D.C. 1989 ABSTRACT Judziewicz, Emmet J., and Thomas R. Soderstrom. Morphological, Anatomical, and Taxonomic Studies in Anomochloa and Streptochaeta (Poaceae: Bambusoideae). Smithsonian Contributions to Botany, number 68,52 pages, 24 figures, 1 table, 1989.-Although resembling the core group of the bambusoid grasses in many features of leaf anatomy, the Neotropical rainforest grass genera Anomochloa and Streptochaeta share characters that are unusual in the subfamily: lack of ligules, exceptionally long microhairs with an unusual morphology, a distinctive leaf blade midrib structure, and 5-nerved coleoptiles. Both genera also possess inflorescences that are difficult to interpret in conventional agrostological terms. Anomochloa is monotypic, and A. marantoidea, described in 1851 by Adolphe Brongniart from cultivated material of uncertain provenance, was rediscovered in 1976 in the wet forests of coastal Bahia, Brazil. The inflorescence terminates in a spikelet and bears along its rachis several scorpioid cyme-like partial inflorescences. Each axis of a partial inflorescence is subtended by a keeled bract and bears as its first appendages two tiny, unvascularized bracteoles attached at slightly different levels. The spikelets are composed of an axis that bears two bracts and terminates in a flower. The lower, chlorophyllous, deciduous spikelet bract is separated from the coriaceous, persistent, corniculate upper bract by a cylindrical, indurate internode. The flower consists of a low membrane surmounted by a dense ring of brown cilia (perigonate annulus) surrounding the andrecium of four stamens, and an ovary bearing a single hispid stigma. -
