"National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment. -

Entre ellos, las abejas constituyen un eslabón esencial en la polinización de angiospermas que durante millones de años desarrollaron estrategias cada vez más específicas para atraerlas. De esta forma se establece una relación muy fuerte entre am- bos, planta-polinizador, y cuanto mayor es la especialización, tal como sucede en un gran número de especies de orquídeas y cactáceas entre otros grupos, ésta se torna más vulnerable ante cambios ambientales naturales o producidos por el hombre. De esta forma, el estudio de este tipo de interacciones resulta cada vez más importante en vista del incremento de áreas perturbadas o modificadas de manera antrópica en las cuales la fauna y flora queda expuesta a adaptarse a las nuevas condiciones o desaparecer. -
Effects of Model-Mimic Frequency on Insect Visitation and Plant Reproduction in a Self-Mimicry Pollination System

AoB PLANTS 9: plx044; doi: 10.1093/aobpla/plx044 Abstract. The proportion of mimics and models is a key parameter in mimetic systems. In monoecious plants with self-mimicry pollination systems, the mimic-model ratio is determined by the floral sex ratio. While an equal sex ratio (1:1) could provide the perfect balance between pollen donors and stigma surfaces able to receive the pollen, an unequal ratio could increase pollination by production of a greater number of rewarding, model flowers. The aim of the present study is to test the differences in visitation frequency and reproductive rates of different mimic and model flower arrays in order to assess the efficacy of the mimetic system in a Begonia cucullata population. -

India *Corresponding Author E-mail: [email protected] Received: 12.09.2018 | Revised: 9.10.2018 | Accepted: 16.10.2018 ABSTRACT The reniformis nematodes of the genus Rotylenchulus (Haplolaimidae: Nematoda) are sedentary semi-endoparasites of numerous crops. There are ten species out of which R. reniformis and R. parvus are important, and three species (R. amanictus, R. clavicadatus, R. leptus) are monophagous: two on monocots and one on Rosids. In general, Rotylenchulus species are capable of feeding from very primitive Magnoliids to plants of advanced category. Preference was distinctly observed towards the plants in Rosids (42.779%) followed by monocots (23.949%) and Asterids (21.755%). The SAI values were also higher for these groups of plants. The study on lineages further revealed intimate affinity to febids (25.594%), followed by commelinids (18.647%), malvids (16.088%), lamiids (11.883%), and campanulids (9.141%). Poales contribution within commelinids was 65.353%. Maximum affinity of Rotylenchulus species was observed by their association with plants from families Poaceae (7), followed by Fabaceae (6), Malvaceae (6), Asteraceae (4), Oleaceae (4), Soanaceae (4) and so on.

Corrected 30-XI-2010. Accepted 07-I-2011. Abstract: Neotropical aquatic ecosystems have a rich aquatic flora. In this report, we have listed the aquatic flora of various habitats of the upper Paraná River floodplain by compiling data from literature and records of our own continuous collections conducted during the period 2007-2009. Our main purposes were to assess the macrophyte richness in the Paraná floodplain, to compare it with other South American wetlands and to assess whether the number of species recorded in South American inventories has already reached an asymptote. We recorded a total of 153 species of macrophytes in the Upper Paraná River floodplain, belonging to 100 genera and 47 families. In our comparative analysis, a clear floristic split from other South American wetlands was shown, except for the Pantanal, which is the closest wetland to the Paraná floodplain and, therefore, could be considered a floristic extension of the Pantanal. -
Conservation of Begonia Germplasm Through Seeds: Characterization of Germination and Vigor in Different Species
CONSERVATION OF BEGONIA GERMPLASM THROUGH SEEDS: CHARACTERIZATION OF GERMINATION AND VIGOR IN DIFFERENT SPECIES THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By: Steven Robert Haba, B.S. Graduate Program in Horticulture and Crop Science The Ohio State University 2015 Thesis Committee: Dr. Pablo Jourdan, Advisor Dr. Mark Bennett Dr. Claudio Pasian Dr. Mark Tebbitt Copyrighted by Steven Robert Haba 2015 ABSTRACT Begonia is one of the most speciose genera of angiosperms, with over 1500 species distributed throughout tropical and subtropical regions; it is also a very important ornamental group of plants displaying a high degree of morphological diversity. This genus is a priority for conservation and germplasm development at the Ornamental Plant Germplasm Center located at The Ohio State University, which currently holds approximately 200 accessions, maintained primarily as clonal plants. In an effort to expand germplasm work in seed storage of Begonia, and in response to a scarcity of published information about begonia seed biology we initiated a project to develop baseline information about germination, dormancy, and stress tolerance of begonia seeds. Because of the extremely small size of begonia seeds (ca. 200 µm) I adapted germination and viability testing protocols typical of Arabidopsis research, to develop relatively efficient quantitative protocols for seed studies. Using this methodology seeds can be routinely germinated on 1% agar plates at 25°C and 16 hours light. To examine the variation in seed characteristics among Begonia accessions in the collection, I selected six species from diverse environments and from different sections of the genus for which we had abundant seed and compared their germination patterns in response to temperature and light, tolerance to high humidity/high temperature stress, and dormancy. -

Jag vill först och främst tacka handledarna Eva Jansson och Karin Martinsson för alla idéer och all tid som ni lagt ner på min uppsats. Dessutom vill jag tacka personalen på Alnarpsbiblioteket, som plockat fram allt material i form av gamla firmakataloger som finns samlade där. Ett särskilt tack vill jag ge till begoniasamlaren Ann-Sofie Asplind, som tålmodigt svarat på mina frågor. Till sist vill jag tacka Sofie Andersson, som parallellt med mig skrivit om fuchsiautbudet i Sverige. Tack för ditt stöd och alla givande diskussionsstunder! 2 Sammanfattning I denna uppsats undersöks det svenska begoniasortimentet mellan 1850 och 1950 med hjälp av gamla priskuranter från handelsträdgårdar och fröfirmor. Syftet med uppsatsen är att undersöka hur begoniasortimentet såg ut och förändrades i Sverige under den aktuella perioden. Genomgången av de gamla priskuranterna har resulterat i en art- och sortlista. I listan finns sammanlagt 62 begoniaarter och primärhybrider samt 280 begoniasorter. Mellan 1860 och 1890 var det vanligare att firmorna sålde arter och primärhybrider än sorter. Efter 1890 såldes fler sorter än arter och primärhybrider i priskuranterna. Rex-begoniorna orsakar en stor sortökning mellan 1890 och 1909. Semperflorens- och Tuberhybrida-grupperna står för den största sortökningen efter 1930 med många sorter som visar sig vara storsäljare. Idag finns det ett intresse för att försöka kartlägga vad som odlats förr i Sverige, något som hittills varit dåligt dokumenterat. För att råda bot på detta har bland annat det nationella Programmet för Odlad Mångfald (POM) startats. POM har som mål att långsiktigt bevara och hållbart utnyttja kulturväxterna i Sverige. -
