Checklist of the Liverworts and Hornworts of the Interior Highlands of North America in Arkansas, Illinois, Missouri and Oklahoma
Checklist of the Liverworts and Hornworts of the Interior Highlands of North America In Arkansas, Illinois, Missouri and Oklahoma Stephen L. Timme T. M. Sperry Herbarium ‐ Biology Pittsburg State University Pittsburg, Kansas 66762 and 3 Bowness Lane Bella Vista, AR 72714 [email protected] Paul Redfearn, Jr. 5238 Downey Ave. Independence, MO 64055 Introduction Since the last publication of a checklist of liverworts and hornworts of the Interior Highlands (1997)), many new county and state records have been reported. To make the checklist useful, it was necessary to update it since its last posting. The map of the Interior Highlands of North America that appears in Redfearn (1983) does not include the very southeast corner of Kansas. However, the Springfield Plateau encompasses some 88 square kilometers of this corner of the state and includes limestone and some sandstone and shale outcrops. The vegetation is typical Ozarkian flora, dominated by oak and hickory. This checklist includes liverworts and hornworts collected from Cherokee County, Kansas. Most of what is known for the area is the result of collections by R. McGregor published in 1955. The majority of his collections are deposited in the herbarium at the New York Botanical Garden (NY). This checklist only includes the region defined as the Interior Highlands of North America. This includes the Springfield Plateau, Salem Plateau, St. Francois Mountains, Boston Mountains, Arkansas Valley, Ouachita Mountains and Ozark Hills. It encompasses much of southern Missouri south of the Missouri River, southwest Illinois; most of Arkansas except the Mississippi Lowlands and the Coastal Plain, the extreme southeastern corner of Kansas, and eastern Oklahoma (Fig. -
Predictive Distribution Model for the Boreal Felt Lichen Erioderma Pedicellatum in Newfoundland, Canada
Vol. 15: 115–127, 2011 ENDANGERED SPECIES RESEARCH Published online November 10 doi: 10.3354/esr00374 Endang Species Res OPENPEN ACCESSCCESS Predictive distribution model for the boreal felt lichen Erioderma pedicellatum in Newfoundland, Canada Yolanda F. Wiersma1,*, Randolph Skinner1,2 1Department of Biology, Memorial University, St. John’s, Newfoundland A1B 3X9, Canada 2Present address: Atlantic Canada Conservation Data Centre, Corner Brook, Newfoundland A2H 751, Canada ABSTRACT: The worldwide population of the boreal felt lichen Erioderma pedicellatum is cur- rently listed as Critically Endangered by the IUCN, with over 95% of the current population resid- ing on the island of Newfoundland, Canada. Surveys of E. pedicellatum habitats and populations have primarily been opportunistic, rather than systematic, in nature. We used a geographic infor- mation system and compiled occurrence data and pseudo-absence data to develop the first pre- dictive spatial distribution model for E. pedicellatum in Newfoundland. Of the suite of 19 models using 4 different parameters examined, the model with distance from coastline and topographic aspect was the best candidate. The final model had low sensitivity (i.e. a low ability to predict false presence), but high specificity (a strong ability to predict true absence). The final predictive model can contribute to future species status assessments and provincial conservation management decisions that require information on probable species distribution. KEY WORDS: Habitat · Lichen · Predictive habitat model · Species distribution · Rare species · Generalized additive model · Newfoundland Resale or republication not permitted without written consent of the publisher INTRODUCTION Canada, E. pedicellatum has been listed as a species of special concern by the Committee on the Status of In conservation biology, determining the spatial Endangered Wildlife in Canada (COSEWIC), and distribution of rare species is a challenge. -

Unfortunately, the number of effective and accessible medicines for the prevention and treatment of these infections is limited. Therefore, in recent years, efforts have been intensified to develop new antiviral medicines or vaccines. In this review article, the structure and activity of the most promising antiviral cyanobacterial products are presented. The antiviral cyanometabolites are mainly active against the human immunodeficiency virus (HIV) and other enveloped viruses such as herpes simplex virus (HSV), Ebola or the influenza viruses. The majority of the metabolites are classified as lectins, monomeric or dimeric proteins with unique amino acid sequences. They all show activity at the nanomolar range but differ in carbohydrate specificity and recognize a different epitope on high mannose oligosaccharides. The cyanobacterial lectins include cyanovirin-N (CV-N), scytovirin (SVN), microvirin (MVN), Microcystis viridis lectin (MVL), and Oscillatoria agardhii agglutinin (OAA). Cyanobacterial polysaccharides, peptides, and other metabolites also have potential to be used as antiviral drugs. -

Abstract: Hypogymnia pulverata is a foliose macrolichen distinguished by its solid medulla and laminal soredia. Though widespread in Asia, it is considered rare in North America, where it is currently known from three widely separated locations in Québec, Oregon, and Alaska. We document the first report of this species from Alaska and from several new localities within south-central and southwestern Alaska. Collema leptaleum is a non-stratified, foliose cyanolichen distinguished by its multicellular, fusiform ascospores and a distinct exciple cell type. It is globally distributed, known most proximately from Kamchatka, Japan and eastern North America, but considered rare in Europe. It has not heretofore been reported from western North America. -

Morphological Diversity of Benthic Nostocales (Cyanoprokaryota/Cyanobacteria) from the Tropical Rocky Shores of Huatulco Region, Oaxaca, México

Box 70–474, México, Distrito Federal (D.F.), México 2 Posgrado en Ciencias Biológicas, Universidad Nacional Autónoma de México (UNAM). * Corresponding author (e–mail: [email protected]) Abstract The supratidal and intertidal zones are extreme biotopes. Recent surveys of the supratidal and intertidal fringe of the state of Oaxaca, Mexico, have shown that the cyanoprokaryotes are frequently the dominant forms and the heterocytous species form abundant and conspicuous epilithic growths. Five of the eight special morphotypes (Brasilonema sp., Myochrotes sp., Ophiothrix sp., Petalonema sp. and Calothrix sp.) from six localities described and discussed in this paper, are new reports for the tropical Mexican coast and the other three (Kyrtuthrix cf. maculans, Scytonematopsis cf. crustacea and Hassallia littoralis) extend their known distribution. Key words: Marine environment, stressful environment, Scytonemataceae, Rivulariaceae Introduction The rocky shore is a highly stressful habitat, due to the lack of nutrients, elevated temperatures and high desiccation related to tidal fluctuation (Nagarkar 2002). Previous works on this habitat report epilithic heterocytous species that are often dominant especially in the supratidal and intertidal fringes (Whitton & Potts 1979, Potts 1980; Nagarkar & Williams 1999, Nagarkar 2002, Diez et al. -

The present research, therefore, aimed to investigate, through a polyphasic approach, the differences in morphological and genotypic features of two cyanobacteria strains isolated from different agricultural and freshwaters areas in Kermanshah province (W Iran). In fact, identification and taxonomy of both Calothrix sp. N42 and Scytonema sp. N11 was problematic and confusing. Challenges arose when the two strains seemed to be Calothrix, because of early unbranched filaments, narrow cells and ending by heterocysts. Along with the progression of growth, branching arise. Therefore, molecular analysis was made and morphometric and genetic (16S rRNA) data were used to characterize the strains in liquid suspension cultures and solid media under photoautotrophic conditions. The results of sequencing the 16S rRNA fragment and phylogenetic comparison strongly indicated that, two strains fall into different phylogenetic clusters. They were named as Calothrix sp. -
