Red Algae (Bangia Atropurpurea) Ecological Risk Screening Summary
Red Algae (Bangia atropurpurea) Ecological Risk Screening Summary U.S. Fish & Wildlife Service, February 2014 Revised, March 2016, September 2017, October 2017 Web Version, 6/25/2018 1 Native Range and Status in the United States Native Range From NOAA and USGS (2016): “Bangia atropurpurea has a widespread amphi-Atlantic range, which includes the Atlantic coast of North America […]” Status in the United States From Mills et al. (1991): “This filamentous red alga native to the Atlantic Coast was observed in Lake Erie in 1964 (Lin and Blum 1977). After this sighting, records for Lake Ontario (Damann 1979), Lake Michigan (Weik 1977), Lake Simcoe (Jackson 1985) and Lake Huron (Sheath 1987) were reported. It has become a major species of the littoral flora of these lakes, generally occupying the littoral zone with Cladophora and Ulothrix (Blum 1982). Earliest records of this algae in the basin, however, go back to the 1940s when Smith and Moyle (1944) found the alga in Lake Superior tributaries. Matthews (1932) found the alga in Quaker Run in the Allegheny drainage basin. Smith and 1 Moyle’s records must have not resulted in spreading populations since the alga was not known in Lake Superior as of 1987. Kishler and Taft (1970) were the most recent workers to refer to the records of Smith and Moyle (1944) and Matthews (1932).” From NOAA and USGS (2016): “Established where recorded except in Lake Superior. The distribution in Lake Simcoe is limited (Jackson 1985).” From Kipp et al. (2017): “Bangia atropurpurea was first recorded from Lake Erie in 1964. During the 1960s–1980s, it was recorded from Lake Huron, Lake Michigan, Lake Ontario, and Lake Simcoe (part of the Lake Ontario drainage). -

The Origin and Evolution of Model Organisms
REVIEWS THE ORIGIN AND EVOLUTION OF MODEL ORGANISMS S. Blair Hedges The phylogeny and timescale of life are becoming better understood as the analysis of genomic data from model organisms continues to grow. As a result, discoveries are being made about the early history of life and the origin and development of complex multicellular life. This emerging comparative framework and the emphasis on historical patterns is helping to bridge barriers among organism-based research communities. Model organisms represent only a small fraction of the these species are receiving an unusually large amount of biodiversity that exists on Earth, although the research attention from the research community and fall under that has resulted from their study forms the core of bio- the broad definition of “model organism”. logical knowledge.

Carl Peter Thunberg and Japanese Natural History
ISSN: 2186-8476, ISSN: 2186-8468 Print Vol. 2 No. 2, June 2013 CARL PETER THUNBERG AND JAPANESE NATURAL HISTORY Bertil Nordenstam Department of Phanerogamic Botany, Swedish Museum of Natural History, Box 50007, SE-10405 Stockholm, SWEDEN. 1 [email protected] ABSTRACT Carl Peter Thunberg (1743-1828) was the most famous of Linnaeus’s pupils and became known as the `Linnaeus of Japan`. However, he was a zoologist almost as much as a botanist and should be remembered also for his lasting contributions to zoology, especially entomology. He published about 160 zoological papers, 90 of which dealt with insects, and he described more than 1,500 new species of insects. One of his first scientific papers dealt with the new grasshopper genus Pneumora from South Africa. Thunberg’s insect collections amount to 36,000 specimens and are largely intact as today. He was also the author of several mammals, such as the Brown Hyaena, and a number of reptiles and fishes, including several new species from Japan. Keywords: Thunberg, Japanese natural history, Entomology, Linnaean disciple, Taxonomy, History of science INTRODUCTION We tend to think of Linnaeus and many of his foremost pupils as botanists. Linnaeus has been famed as ‘ Princeps botanicorum’ , and his perhaps most successful disciple, Carl Peter Thunberg (1743—1828; Fig. 1), has been named the ‘Father of South African Botany’ and also the ‘Linnaeus of Japan’. However, most of the Linnaean apostles, like Linnaeus himself, were medical doctors and zoologists as well – in fact they are better labeled as naturalists, or natural history scientists. Their academic positions were not in botany, but rather in medicine and botany, and similar combinations. -

Elias Magnus Fries Och Carl Adolph Agardh Om Vetenskaplig Metodik Och Möjligheten Att Konstruera Ett Naturligt System Inom Botaniken
Elias Magnus Fries och Carl Adolph Agardh om vetenskaplig metodik och möjligheten att konstruera ett naturligt system inom botaniken Lunds universitet Magnus Krook Språk- och litteraturcentrum Magisteruppsats LATM04 Lund 2014 Handledare: Professor Arne Jönsson Abstract Kring sekelskiftet 1800 dominerades den svenska botaniska forskningen av Carl von Linnés vetenskapliga gärning som hos hans omedelbara efterföljare stelnat i ortodoxi och brist på kreativitet. Den från Tyskland emanerande romantiska naturfilosofin med Friedrich Wilhelm Joseph von Schelling som förgrundsgestalt gav efterhand avtryck även inom den svenska naturvetenskapen. Botanikerna Carl Adolph Agardh (1785-1859) och Elias Magnus Fries (1794-1878) var båda djupt påverkade av den romantiska filosofin i sina vetenskapliga arbeten. En av romantikens centrala idéer var att det bakom de olika naturalstrens mångfald fanns en enhet för naturforskaren att upptäcka, och både Agardh och Fries omfattade denna tanke fullt ut. Agardh var huvudsakligen specialiserad på alger, Fries ägnade sig åt svampar och lavar. Linné hade åstadkommit ett artificiellt system för växterna som fått stor spridning, men hans ouppfyllda mål var att upprätta ett naturligt system. Agardh och Fries tog vid där Linné slutade. Med utgångspunkt från den romantiska filosofin angriper de växtvärldens systematisering från var sin ände. Fries börjar med de högst utvecklade växterna och arbetar sig nedåt. Genom en strikt logisk metod delar han in växtvärlden i allt mindre enheter. Agardh avvisar däremot logikens användning inom biologin. Han utgår från de lägst utvecklade växterna och arbetar sig uppåt, en process där de empiriska erfarenheterna bit för bit fogas samman till en helhet. Agardh och Fries företrädde utvecklingstankar som stod i stark motsättning till den moderna evolutionsteorin. -
Proposal for Practical Multi-Kingdom Classification of Eukaryotes Based on Monophyly 2 and Comparable Divergence Time Criteria

There are multiple available classification 12 systems that all suffer from differences in naming, incompleteness, presence of multiple non- 13 monophyletic entities and poor correspondence of divergence times. These issues render 14 taxonomic comparisons across the main groups of eukaryotes and all life in general difficult 15 at best. By using the monophyly criterion, roughly comparable time of divergence and 16 information from multiple phylogenetic reconstructions, I propose an alternative 17 classification system for the domain Eukarya to improve hierarchical taxonomical 18 comparability for animals, plants, fungi and multiple protist groups. Following this rationale, 19 I propose 32 kingdoms of eukaryotes that are treated in 10 subdomains. These kingdoms are 20 further separated into 43, 115, 140 and 353 taxa at the level of subkingdom, phylum, 21 subphylum and class, respectively (http://dx.doi.org/10.15156/BIO/587483). -

N eUMANN Botany Department, 3190 Maile Way, University of Hawai‘i, Honolulu, Hawai‘i 96822 USA; email: [email protected] As part of the Hawaiian Freshwater Algae Biodiversity Survey (2009 –2012) we have been documenting algae (with a focus on macroalgae) associated with numerous habitats, including high elevation bogs on the main Hawaiian islands. Bogs represent a very dif - ferent environment from streams, where most of our collections originated, in that they have much lower (or absent) water flow, lower temperatures due to high elevation, and usually acidic pH conditions. This paper provides an updated taxonomic checklist for high elevation bog-associated algae in Hawai‘i and compares our identifications to historical literature records. Hawaiian bog ecosystems are characterized as small, isolated and permanently wet areas, which tend to be scarce (only 1 –2 present on each large island), consisting of hum - mocks of native sedges and dwarf individuals of native plant species (Ziegler 2002). in general, bogs represent acidic, dystrophic environments that have a very characteristic lit - toral flora (Wetzel 2001).
