Wide Variation in Post-Emergence Desiccation Tolerance of Seedlings of Fynbos Proteoid Shrubs ⁎ P.J
Available online at www.sciencedirect.com South African Journal of Botany 80 (2012) 110–117 www.elsevier.com/locate/sajb Wide variation in post-emergence desiccation tolerance of seedlings of fynbos proteoid shrubs ⁎ P.J. Mustart a, A.G. Rebelo b, J. Juritz c, R.M. Cowling a, a Botany Department, Nelson Mandela Metropolitan University, P.O. Box 77000, Port Elizabeth 6301, South Africa b Kirstenbosch Research Centre, South African National Biodiversity Institute, Private Bag X7, Claremont 7735, South Africa c Department of Statistical Science, University of Cape Town, Private Bag, Rondebosch 7700, South Africa Received 20 February 2012; received in revised form 13 March 2012; accepted 21 March 2012 Abstract Fynbos Proteaceae that are killed by fire and bear their seeds in serotinous cones (proteoids), are entirely dependent on seedling recruitment for persistence. Hence, the regeneration phase represents a vulnerable stage of the plant life cycle. In laboratory-based experiments we investigated the effect of desiccation on the survival of newly emerged seedlings of 23 proteoid species (Leucadendron and Protea) occurring in a wide variety of fynbos habitats. We tested the hypothesis that species of drier habitats would be more tolerant of desiccation than those from more moist areas. Results showed that with no desiccation treatment, or with desiccation prior to radicle emergence, all species germinated to high levels. However, with desiccation treatments imposed after radicle emergence, there were significant declines in seedling emergence after subsequent re-wetting. Furthermore, other than three species that grow in waterlogged habitats, germination responses could not be reliably modeled as a function of soil moisture variables. -

Are All Four-Day School Weeks Created Equal? a National Assessment of Four-Day School Week Policy Adoption and Implementation*
Are All Four-Day School Weeks Created Equal? A National Assessment of Four-Day School Week Policy Adoption and Implementation* Paul N. Thompson* John M. Schuna Jr. Assistant Professor of Economics Assistant Professor of Kinesiology School of Public Policy School of Biological and Population Health Oregon State University Sciences 340 Bexell Hall Oregon State University Corvallis, OR 97331 118H Milam Hall Corvallis, OR 97331 Katherine Gunter Emily J. Tomayko Professor and Extension Specialist Assistant Professor of Research School of Biological and Population Health Center for American Indian and Rural Health Sciences Equity Oregon State University Montana State University 247 Hallie E. Ford Center 308 Reid Hall Corvallis, OR 97331 Bozeman, MT 59715 Abstract: Four-day school weeks are used in over 1,600 schools across 24 states, but little is known about adoption and implementation of these types of school calendars. Through examinations of school calendars and correspondence with school districts, we have compiled the most complete four-day school week dataset to date. We use this unique database to conduct a comprehensive analysis of four-day school week policy adoption and implementation. We find adoption of four-day school weeks is often financially-motivated, and has generally remained a small, rural district phenomenon. These schedules feature a day off once a week – often Friday – with increased time in school on each of the remaining four school days that, on average, is nearly an hour longer than the national average among five-day schools. Four-day school week schedules average only 148 yearly school days, yielding yearly time in school that is below the national average for five-day schools despite the longer school days. -
Outline of Angiosperm Phylogeny
Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page. Basal Angiosperms (ANITA grade) Amborellales Amborellaceae, sole family, the earliest branch of flowering plants, a shrub native to New Caledonia – Amborella Nymphaeales Hydatellaceae – aquatics from Australasia, previously classified as a grass Cabombaceae (water shield – Brasenia, fanwort – Cabomba) Nymphaeaceae (water lilies – Nymphaea; pond lilies – Nuphar) Austrobaileyales Schisandraceae (wild sarsaparilla, star vine – Schisandra; Japanese -

1 Original Research Article 2 3 THE MALOIDEAE (ROSACEAE) STRUCTURAL AND FUNCTIONAL FEATURES 4 DETERMINING PASSIVE IMMUNITY TO MYCOSIS 5 6 7 With the help of microscopic methods the leaves and fruits surface tissues of plants of four 8 genera of the Maloideae subfamily were screened: Malus Mill., Pyrus L., Cydonia Mill., 9 Mespilus L., as model objects, and attempts were made to explain the dependence of mycosis 10 damage on microstructural features. The species composition of fungi that cause damage to the 11 Maloideae leaves and fruits in the Russia southern regions is analyzed. It is established that 12 among pathogens with different types of parasitism there are common excitants, as well as 13 highly specialized, more represented on Mespilus germanica. Higher resistance to the complex 14 of fungal diseases, in comparison with apple and pear, was found in quince and medlar. This 15 stability at the initial stage of the pathological process is associated with structural features such 16 as micromorphology of the fruits and stomata cuticle in the abaxial leaves epidermis. The leaves 17 stomatal cracks of the medlar are narrow with raised outgrowths, on the surface of the fruit – the 18 layered structure of the cuticular layer. Quince has a powerful continuous cuticular cover. 19 Compared with Malus and Pyrus, Cydonia and Mespilus also have a large (30 % or more) 20 polyphenol content in the pericarp outer layer cells. In addition to the gender-specific differences 21 in the microstructure of the integumentary tissues and the content of polyphenols affecting the 22 resistance to pathogens at the stage of their penetration, general patterns of leaf surface 23 formation, such as hypostomacy, anomocytic stomata, folded microrelief of the cuticular surface, 24 and the presence of single and multicellular trichomes are noted. -

Monocotyledons and Gymnosperms of Puerto Rico and the Virgin Islands
SMITHSONIAN INSTITUTION Contributions from the United States National Herbarium Volume 52: 1-415 Monocotyledons and Gymnosperms of Puerto Rico and the Virgin Islands Editors Pedro Acevedo-Rodríguez and Mark T. Strong Department of Botany National Museum of Natural History Washington, DC 2005 ABSTRACT Acevedo-Rodríguez, Pedro and Mark T. Strong. Monocots and Gymnosperms of Puerto Rico and the Virgin Islands. Contributions from the United States National Herbarium, volume 52: 415 pages (including 65 figures). The present treatment constitutes an updated revision for the monocotyledon and gymnosperm flora (excluding Orchidaceae and Poaceae) for the biogeographical region of Puerto Rico (including all islets and islands) and the Virgin Islands. With this contribution, we fill the last major gap in the flora of this region, since the dicotyledons have been previously revised. This volume recognizes 33 families, 118 genera, and 349 species of Monocots (excluding the Orchidaceae and Poaceae) and three families, three genera, and six species of gymnosperms. The Poaceae with an estimated 89 genera and 265 species, will be published in a separate volume at a later date. When Ackerman’s (1995) treatment of orchids (65 genera and 145 species) and the Poaceae are added to our account of monocots, the new total rises to 35 families, 272 genera and 759 species. The differences in number from Britton’s and Wilson’s (1926) treatment is attributed to changes in families, generic and species concepts, recent introductions, naturalization of introduced species and cultivars, exclusion of cultivated plants, misdeterminations, and discoveries of new taxa or new distributional records during the last seven decades. -

DIFFERENTIATION OF MESPILUS AND CRATAEGUS, EXPANSION OF ×CRATAEMESPILUS, WITH SUPPLEMENTARY OBSERVATIONS ON DIFFERENCES BETWEEN THE CRATAEGUS AND AMELANCHIER CLADES JAMES B. PHIPPS Department of Biology, The University of Western Ontario, London, Ontario N6A 5B7, Canada; email: [email protected] Abstract The paper argues the position for retaining a monotypic Mespilus, i.e., in the sense of M. germanica, the medlar. Recent cladistic papers lend support for Mespilus being sister to Crataegus, and there is a clear morphological distinction from Cra- taegus, emphasized by adaptation to carnivore frugivory. Mespilus secured, the paper then treats each of the known hybrids between Mespilus and Crataegus, making the new combination Crataemespilus ×canescens (J.B. Phipps) J.B. Phipps. Keywords: Crataemespilus ×canescens (J.B. Phipps) J.B. Phipps comb. nov.; inflorescence position; medlar; Mespilus a folk-genus; Mespilus distinct from Crataegus; Rosaceae; taxonomic history of Mespilus Introduction The author has a long-standing interest in generic delimitation in the Maloid genera of the Rosaceae (Maleae Small, formerly Maloideae C. Weber, Pyrinae Dumort.), as shown particularly in a series of papers with K. Robertson, J. Rohrer, and P.G. Smith (Phipps et al. 1990, 1991; Robertson at al. 1991, 1992; Rohrer at al. 1991, 1994) which treated all 28 genera of Maleae as recognised by us.
