CYPERACEAE Sauergrasgewächse SEDGES, aka BIESIES, SEGGEN Formally described in 1789 by De Jussieu. The family name is derived from the genus name Cyperus, from the Greek kupeiros, meaning sedge. Many species are grass-like, being tufted, with long, thin, narrow leaves, jointed stems, & branched inflorescence of small flowers, & are horticulturally lumped with grasses as graminoids. Archer (2005) suggests the term graminoid be used for true grasses, & cyperoid be used for sedges. (If physical anthropologists have hominoids & hominids, why don’t we have graminoids & graminids?) There are approximately 104 genera, 4 subfamilies, 14 tribes, & about 5000 species worldwide, with 27 genera & 843 species in North America (Ball et al 2002).

Other taxa have been added to the initial list of plants, so that, the total number of taxa registered by the authors in Rarău Massif amount to 1443 taxa (1133 species and 310 subspecies, varieties and forms). There was signaled out the alien taxa on the surveyed area (18 species) and those dubious presence of some taxa for the same area (17 species). Also, there were listed all the vascular plants, protected by various laws or regulations, both internal or international, existing in Rarău (i.e. 189 taxa). Finally, there has been assessed the degree of wild flora conservation, using several indicators introduced in literature by Nowak, as they are: conservation indicator (C), threat conservation indicator) (CK), sozophytisation indicator (W), and conservation effectiveness indicator (E). Key words: Vascular flora, Rarău Massif, Romania, conservation indicators. 1.

LATERIFLORUS GMEL. Clarke the Although saw type of Scirpus erectus Poir. in the Paris Herbarium he misapplied the name to a quite different species occurring in Madagascar, S. and E. Asia, and tropical Australia. Herein he was followed by Ridley, Merrill, Backer, and others. It has now generally been that the accepted correct name of this species is Scirpus juncoides Roxb. and that the name Scirpus erectus Poir. does not belong to its synonymy. After having examined the type of S. erectus I am convinced that the cleared Chermezon question was admirably up by (see Arch. Bot. 4, 1931, 26, and also in Humbert, Fl. Madag., fam. 29, 1937, 149). is much Scirpus erectus nearer to the European S. supinus L. than to S. juncoides Roxb. It differs from S. supinus by the larger spikelets, the larger, more distinctly mucronate glumes, the bristly appendage of the bifid and the connective, style, the larger, biconvex, only faintly wavy- ridged, elliptic or suborbicular nuts. It is an African species extending from the Mediterranean region through tropical Africa to Madagascar and Mauritius. There can be no doubt that Isolepis uninodis Delile is conspecific Delile’s with Scirpus erectus Poir. description is very accurate: “épis ovoïdes-lanceolés écailles deux cylindriques, ovales, aiguës ... stigmates ... graine lenticulaire, transversalement vers les bords.” The ... rugueux differences with Scirpus supinus are clearly indicated: “ses graines [du S. supinus] sont ovoïdes-cunéiformes, trigones, ridées transversalement sur toute leur surface; ses styles sont trifides.” Moreover, Delile’s excellent figure leaves no doubt whatever on the identity of his species.

    Salinity As the Major Factor Affecting Scirpus Maritimus Annual Dynamics Evidence from Field Data and Greenhouse Experiment

    Aquatic Botany 77 (2003) 111–120 Salinity as the major factor affecting Scirpus maritimus annual dynamics Evidence from field data and greenhouse experiment Ana I. Lillebø∗, Miguel A. Pardal, João M. Neto, João C. Marques Department of Zoology, University of Coimbra, Institute of Marine Research, Coimbra 3004-517, Portugal Received 6 June 2002; received in revised form 3 June 2003; accepted 6 June 2003 Abstract During the life cycle of Scirpus maritimus, ramets produce photosynthetic shoots that are active for a single growing season and only the belowground parts persist into the next year. Several authors have described that the growing season of S. maritimus in Europe and North America occurs between April and September of each year. In the Mondego estuary (western coast of Portugal) the life cycle of S. maritimus showed an opposite seasonal pattern, with a growing season from January to April/May. It was hypothesised that seasonal fluctuations in salinity, connected to salinity tolerance, could explain this contrasting annual cycle. This hypothesis was tested using a greenhouse experiment. Exposure to different salinities significantly affected plant survival. During the first 10 days, the survival curves were very similar, which suggested that the plants were able to tolerate high salinity for short periods. After 2 weeks of exposure, the plants started to show differences, with increased mortality following the increase in salinity. Results show that a peculiar seasonal variation of salinity in the Mondego estuary affected the S. maritimus life cycle in this ecosystem and may explain the differences between these western Portugese populations and other European and North American populations.

    YELLOWSTONE THE FIRST NATIONAL PARK THE HISTORY BEHIND YELLOWSTONE Long before herds of tourists and automobiles crisscrossed Yellowstone’s rare landscape, the unique features comprising the region lured in the West’s early inhabitants, explorers, pioneers, and entrepreneurs. Their stories helped fashion Yellowstone into what it is today and initiated the birth of America’s National Park System. Native Americans As early as 10,000 years ago, ancient inhabitants dwelled in northwest Wyoming. These small bands of nomadic hunters wandered the country- side, hunting the massive herds of bison and gath- ering seeds and berries. During their seasonal travels, these predecessors of today’s Native American tribes stumbled upon Yellowstone and its abundant wildlife. Archaeologists have discov- ered domestic utensils, stone tools, and arrow- heads indicating that these ancient peoples were the first humans to discover Yellowstone and its many wonders. As the region’s climate warmed and horses Great Fountain Geyser. NPS Photo by William S.

    River Bulrush Bolboschoenus fluviatilis (Torr.) Sajak State Status: None Federal Status: None Description: River Bulrush (Bolboschoenus fluviatilis) is a robust, leafy, perennial sedge (family Cyperaceae) of river shores, inland marshes, and freshwater to brackish tidal wetlands. It often grows in dense, sometimes entirely vegetative stands. Aids to identification: River Bulrush has a sharply triangular stem, or culm, 0.6 to 1.5 m (2–5 ft.) in height, which arises from an elongate rhizome, and bears numerous leaves. The leaf blades are 6 to 22 mm (0.24– 0.9 in.) in width, and have a sheath with a papery convex (or sometimes concave) orifice. The reduced flowers are each subtended by overlapping translucent scales, arranged in brown, ovoid (egg-shaped) to lance-ovoid spikelets, 12 to 25 mm (0.5–1 in.) in length. The inflorescence is umbel-like, with 10 to 40 terminal spikelets; most are borne on 4 to 7 slender, drooping rays, but some are sessile, forming a central cluster.

Strong OBL Common Name Growth Form Sturdy Bulrush Emergent, rhizomatous perennial Synonym Habitat Scirpus robustus Pursh Intermixed with marsh plants Group in elevated saline and brackish marshes Monocotyledon Family Cyperaceae Schoenoplectus robustus 1 Seed Collection Observe inflorescence development of Schoenoplectus robustus in the field. In coastal Mississippi and along the northern Gulf of Mexico this generally occurs between July and September (Eleuterius and Caldwell 1984); however, this may vary from year to year depending on weather conditions. The inflorescence of Schoenoplectus robustus is composed of ovoid to cylindric shaped spikelets with dark reddish-brown scales. Inside most of the mature spikelets there is a shiny brown indehiscent (remaining closed at maturity) dried fruit, called an achene, that contains a single seed. The seeds can be harvested in the field by cutting the stems above and below the inflorescence and placing them into plastic bags. Not all inflorescences may mature at the same time. Repeated site visits may be necessary to collect inflorescences that ripen at different times. 2 Seed Preparation The Schoenoplectus robustus spikelets (which contain the achenes) should be processed as soon as possible after collection. The achenes can be released from the spikelets by rubbing the spikelets by hand. Small amounts of the collected achenes can then be spread out on white paper and the remaining undesirable material is removed with forceps (tweezers). This is a time-consuming process, but essential to the successful storage conditions of the seeds. Garbisch and McIninch (1992) have reported there are approximately 170,000 achenes per pound dry weight.

Paleontology, University of Alberta, 2009 Submitted to the graduate degree program in Ecology & Evolutionary Biology and the Graduate Faculty of the University of Kansas in partial fulfillment of the requirements for the degree of Doctor of Philosophy. Chair: Benjamin Sikes Mark Holder Ari Jumpponen Leonard Krishtalka Jennifer Roberts Date Defended: 04 December 2018 ii The dissertation committee for Ashley A Klymiuk certifies that this is the approved version of the following dissertation: Microbiological insights into ecology and taphonomy of prehistoric wetlands. Chair: Benjamin Sikes Date Approved: 7 December 2018 iii Abstract In the course of this dissertation, I present investigations of the microbial constituents of fossil plants preserved at an anatomical level of detail, and detail the results of an ecological survey of root-endogenous fungi within the cosmopolitan emergent macrophyte, Typha. These studies together elucidate processes in the taphonomy of fossil plants. Biostratinomy is addressed through descriptions of saprotrophic communities within the Eocene Princeton Chert mire assemblage, and within a Carboniferous fern which previous studies had suggested contained fossilized actinobacteria. Re-investigation of the ‘actinobacteria’ suggests instead that the structures are disordered ferrous dolomites, raising implications for the contribution of sulfate- reducing bacteria to the early-diagenesis mineralization of plants preserved in carbonaceous concretions. The fossilized remains of saprotrophic and putatively endophytic fungi within roots of in-situ plants from the Princeton Chert also provide insight into early diagenesis. Some of the fungi described herein are preserved in several co-occurring developmental phases, providing evidence that early phases of silicification in this assemblage were rapid.
