  • How Illinois Kicked the Exotic Habit
    HOW ILLINOIS KICKED THE EXOTIC HABIT Francis M. Harty Illinois Department of Conservation 2005 Round Bam Road Champagne, IL 61821 Introduction For the purpose of this paper, an exotic species is defined as "a plant or animal not native to North America." The history of folly surrounding the premeditated and accidental introduction of exotic animals has been well-documented (DeVos et al. 1956, Elton 1958, Hall 1963, Laycock 1966, Ehrenfeld 1970, Bratton 1974/1975, Howe and Bratton 1976, Moyle 1976, Courtenay 1978, Coblentz 1978, Iverson 1978, Weller 1981, Bratton 1982, Vale 1982, and Savidge 1987). In 1963, Dr. E. Raymond Hall wrote, "Introducing exotic species of vertebrates is unscientific, economically wasteful, politically shortsighted, and biologically wrong." Naturalizing exotic species are living time bombs, but no one knows for sure how much time we have. For example, the ring­ necked pheasant (Phasianus colchicus), touted as the Midwestern example of a good exotic introduction, has recently developed a nefarious relationship with the greater prairie chicken (Tympanuchus cupido) in Illinois. Parasitism of prairie chicken nests by hen pheasants and harassment of displaying male chickens by cock pheasants are contributing to the decline of prairie chickens in Illinois (Vance and Westemeier 1979). The interspecific competition between the exotic pheasant (which is expanding its range in Illinois) and the native prairie chicken (which is an endangered species in Illinois) may be the final factor causing the extirpation of the prairie chicken from Illinois; it has already been extirpated from neighboring Indiana. In 1953, Klimstra and Hankla wrote, "In connection with the development of a pheasant adapted to southern conditions, the compatibility of pheasants and quail (Colinus virginianus) needs to be evaluated.

Dragan Tsankov, 1164 Sofia, Bulgaria; mstoyneva@uni-sofia.bg * Correspondence: buzunov@uni-sofia.bg Abstract: The review summarizes the available knowledge on toxins and their producers from rather disparate algal assemblages of aeroterrestrial, airborne and other versatile extreme environments (hot springs, deserts, ice, snow, caves, etc.) and on phycotoxins as contaminants of emergent concern in soil and plants. There is a growing body of evidence that algal toxins and their producers occur in all general types of extreme habitats, and cyanobacteria/cyanoprokaryotes dominate in most of them. Altogether, 55 toxigenic algal genera (47 cyanoprokaryotes) were enlisted, and our analysis showed that besides the “standard” toxins, routinely known from different waterbodies (microcystins, nodularins, anatoxins, saxitoxins, cylindrospermopsins, BMAA, etc.), they can produce some specific toxic compounds. Whether the toxic biomolecules are related with the harsh conditions on which algae have to thrive and what is their functional role may be answered by future studies. Therefore, we outline the gaps in knowledge and provide ideas for further research, considering, from one side, Citation: G¨аrtner, G.; the health risk from phycotoxins on the background of the global warming and eutrophication and, ¨а Stoyneva-G rtner, M.; Uzunov, B.

  • Adaptations of Cyanobacterium Nostoc Commune to Environ- Mental Stress: Comparison of Morphological and Physiological Markers
    CZECH POLAR REPORTS 8 (1): 84-93, 2018 Adaptations of cyanobacterium Nostoc commune to environ- mental stress: Comparison of morphological and physiological markers between European and Antarctic populations after re- hydration Dajana Ručová1, Michal Goga1, Marek Matik2, Martin Bačkor1* 1Department of Botany, Institute of Biology and Ecology, Faculty of Science, University of Pavol Jozef Šafárik, Mánesova 23, 041 67 Košice, Slovakia 2Institute of Geotechnics, Slovak Academy of Sciences, Watsonova 45, 040 01 Košice, Slovakia Abstract Availability of water may influence activities of all living organisms, including cyano- bacterial communities. Filamentous cyanobacterium Nostoc commune is well adapted to wide spectrum of ecosystems. For this reason, N. commune had to develop diverse pro- tection strategies due to exposition to regular rewetting and drying processes. Few studies have been conducted on activities, by which cyanobacteria are trying to avoid water deficit. Therefore, the present study using physiological and morphological param- eters is focused on comparison between European and Antarctic ecotypes of N. commune during rewetting. Gradual increase of FV/FM ratios, as the markers of active PS II, demonstrated the recovery processes of N. commune colonies from Europe as well as from Antarctica after time dependent rehydration. During the initial hours of rewetting, there was lower content of soluble proteins in colonies from Antarctica in comparison to those from Europe. Total content of nitrogen was higher in European ecotypes of N. commune. Significantly higher frequency of occurrence of heterocysts in Antarctic ecotypes was observed. The heterocyst cells were significantly longer in Antarctic ecotypes rather than European ecotypes of N. commune.

  • The Genus Astragalus (Fabacaeae) in Illinois
    Transactions of the Illinois State Academy of Science received 7/14/03 (2003), Volume 97, #1, pp. 11-18 accepted 11/9/03 The Genus Astragalus (Fabacaeae) in Illinois William E. McClain, Adjunct Research Associate in Botany Illinois State Museum, Springfield, Illinois 62706 and John E. Ebinger, Professor Emeritus of Botany Eastern Illinois University, Charleston, Illinois 61920 ABSTRACT Herbarium and field searches were made to determine the former and current distribution of the five Astragalus species (milk vetch) known from Illinois. Of these, the adventive A. agrestis Doug. has been reported once from the state. The native species A. crassicar- pus Nutt., A. distortus Torrey & Gray, A. tennesseensis Gray, and A. canadensis L. have experienced population declines due to habitat destruction. Astragalus canadensis is a widely distributed species of high quality prairie remnants, A. crassicarpus is known primarily from glacial drift prairies in Macoupin County, A. tennesseensis is known from a single site in Tazewell County, while only six small colonies of A. distortus survive, all from wind blown sand and loess deposits in Cass, Mason and Scott counties. Astragalus crassicarpus and A. tennesseensis are presently listed as endangered in Illinois, and endangered status is recommended for A. distortus. INTRODUCTION The genus Astragalus L., (milk vetch) is represented by more than 2,000 species in the Northern Hemisphere including 375 that occur in the United States (Isely 1998). Many are prairie and plains species of the western United States and Canada, but some occur in woodlands, barrens, and glades in the eastern United States (Gleason and Cronquist 1991). As members of the Fabaceae (Legume or Pulse Family), the genus belongs to the tribe Galegeae.

(2015): Seed of the threatened annual legume, Astragalus contortuplicatus, can survive over 130 years of dry storage. – Preslia 87: 319–328. Long-term seed viability is of crucial importance for short-lived species, since persistent seed banks can buffer the fluctuations in the establishment of plants from year to year. Temporarily flooded habitats are an unpredictable environment for plants, and for some species the only chance they have of surviving is the formation of persistent seed banks. Astragalus contortuplicatus is an annual species of periodically flooded habitats and is considered an endangered species in Hungary. Alto- gether 1993 seeds of this species were tested in a germination experiment: 1200 were freshly har- vested and 793 were collected from herbarium specimens of various ages.

Phylogenetic analysis indicates that it belongs to a Nostoc sensu stricto clade, which contains strains identified asN. commune. Nostoc cf. commune is found in two close areas: Site I (protected from direct sunlight by a wall), where it forms biofilms on mortar with Trentepohlia aurea; and Site II, where it grows on exposed stucco with the accompanying organism Scytonema guyanense. Over the year, in a habitat dictated by alternating wet and dry seasons, the organisms vary in appearance. Its life cycle comprises two seasonally–determined developmental stages (growth during the wet season and dormancy during the dry season) and two transitional stages (preparation for the dry season, and rehydration and recovery). At the beginning of the wet season the resistant stages from the previous dry season are rehydrated and form propagula, that adopt a colonial shape surrounded by a gelatinous sheath.

  • Abstract Phylogenetic Analysis of the Symbiotic
    ABSTRACT PHYLOGENETIC ANALYSIS OF THE SYMBIOTIC NOSTOC CYANOBACTERIA AS ASSESSED BY THE NITROGEN FIXATION (NIFD) GENE by Hassan S. Salem Members of the genus Nostoc are the most commonly encountered cyanobacterial partners in terrestrial symbiotic systems. The objective of this study was to determine the taxonomic position of the various symbionts within the genus Nostoc, in addition to examining the evolutionary relationships between symbiont and free-living strains within the genus by analyzing the complete sequences of the nitrogen fixation (nif) genes. NifD was sequenced from thirty-two representative strains, and phylogenetically analyzed using the Maximum likelihood and Bayesian criteria. Such analyses indicate at least three well-supported clusters exist within the genus, with moderate bootstrap support for the differentiation between symbiont and free-living strains. Our analysis suggests 2 major patterns for the evolution of symbiosis within the genus Nostoc. The first resulting in the symbiosis with a broad range of plant groups, while the second exclusively leads to a symbiotic relationship with the aquatic water fern, Azolla.
