  • Scouring-Rush Horsetail Scientific Name: Equisetum Hyemale Order
    Common Name: Scouring-rush Horsetail Scientific Name: Equisetum hyemale Order: Equisetales Family: Equisetaceae Wetland Plant Status: Facultative Ecology & Description Scouring-rush horsetail is an evergreen, perennial plant that completes a growing season in two years. At maturity, scouring-rush horsetail usually averages 3 feet in height but can be range anywhere from 2 to 5 feet. It can survive in a variety of environments. One single plant can spread 6 feet in diameter. It has cylindrical stems that averages a third of an inch in diameter. Noticeably spotted are the jointed unions that are located down the plant. The stems are hollow and don’t branch off into additional stems. Also, scouring- rush horsetail has rough ridges that run longitudinal along the stem. Although not covered in leaves, tiny leaves are joined together around the stem which then forms a black or green band, or sheath at each individual joint on the stem. This plant has an enormous root system that can reach 6 feet deep and propagates in two ways: rhizomes and spores. Incredibly, due to the fact that this plant is not full of leaves, it is forced to photosynthesize through the stem rather than leaves. Habitat Scouring-rush horsetail is highly tolerant of tough conditions. It can survive and thrive in full sun or part shade and can successfully grow in a variety of soil types. It can also grow in moderate to wet soils, and can survive in up to 4 inches of water. Distribution Scouring-rush horsetail can be found throughout the United States, Eurasia, and Canada.

  • Ferns and Fern Allies
    PTERIDOPHYTES Ferns and Fern Allies The Pteridophytes (seedless vascular plants) consist of 4 Divisions circa 1993 (Flora of NA, V. 1) due to their similarities (discussed below) in anatomy and morphology and their differences from higher seed plants*. World-wide there are about 25 families, 255+ 1- Lycopodiophyta (Club-Mosses) genera, and perhaps 10,000+ species. In North America there are about 77 genera and 440+ 2- Psilotophyta (Whisk Ferns) species (Flora of North America, V.2). – see 3- Equisetophyta (Horsetails) next slide for more information. 4- Polypodiophyta (True Ferns) Reproduction is by spores (also by vegetative or asexual means) - no true flowers, fruits or seeds are present. They exhibit a life cycle of alternation of generations (sporophyte and gametophyte). The sporophyte generation is the larger phase that we commonly see in the field and produces haploid spores by meiosis. These spores disseminate mostly by wind (sometimes water), produce a Prothallus (gametophyte generation), a very small, free-living or independent phase, that produces both sperm (from antheridia) and eggs (from archegonia) – gametes or sex cells. The sperm swims to the egg on its own prothallus or on another (water must be present in most cases) and fertilization results with the production of the diploid generation from which a new sporophyte generation is produced. *Botanists today, due to DNA studies and many additional examples, believe that the Lycophytes branched early (forming a distinct Clade or branch of a phylogenetic tree) and the Pteridophytes form another later distinct Clade (or branch) that is closer to the seed plants (a revised classification is below).

    Palaeogeography, Palaeoclimatology, Palaeoecology 564 (2021) 110185 Contents lists available at ScienceDirect Palaeogeography, Palaeoclimatology, Palaeoecology journal homepage: www.elsevier.com/locate/palaeo Modern analogs reveal the origin of Carboniferous coal balls Gregory Retallack * Department of Earth Science, University of Oregon, Eugene, Oregon 97403-1272, USA ARTICLE INFO ABSTRACT Keywords: Coal balls are calcareous peats with cellular permineralization invaluable for understanding the anatomy of Coal ball Pennsylvanian and Permian fossil plants. Two distinct kinds of coal balls are here recognized in both Holocene Histosol and Pennsylvanian calcareous Histosols. Respirogenic calcite coal balls have arrays of calcite δ18O and δ13C like Carbon isotopes those of desert soil calcic horizons reflecting isotopic composition of CO2 gas from an aerobic microbiome. Permineralization Methanogenic calcite coal balls in contrast have invariant δ18O for a range of δ13C, and formed with anaerobic microbiomes in soil solutions with bicarbonate formed by methane oxidation and sugar fermentation. Respiro­ genic coal balls are described from Holocene peats in Eight Mile Creek South Australia, and noted from Carboniferous coals near Penistone, Yorkshire. Methanogenic coal balls are described from Carboniferous coals at Berryville (Illinois) and Steubenville (Ohio), Paleocene lignites of Sutton (Alaska), Eocene lignites of Axel Heiberg Island (Nunavut), Pleistocene peats of Konya (Turkey), and Holocene peats of Gramigne di Bando (Italy). Soils and paleosols with coal balls are neither common nor extinct, but were formed by two distinct soil microbiomes. 1. Introduction and Royer, 2019). Although best known from Euramerican coal mea­ sures of Pennsylvanian age (Greb et al., 1999; Raymond et al., 2012, Coal balls were best defined by Seward (1895, p.

  • The Joggins Fossil Cliffs UNESCO World Heritage Site: a Review of Recent Research
    The Joggins Fossil Cliffs UNESCO World Heritage site: a review of recent research Melissa Grey¹,²* and Zoe V. Finkel² 1. Joggins Fossil Institute, 100 Main St. Joggins, Nova Scotia B0L 1A0, Canada 2. Environmental Science Program, Mount Allison University, Sackville, New Brunswick E4L 1G7, Canada *Corresponding author: <[email protected]> Date received: 28 July 2010 ¶ Date accepted 25 May 2011 ABSTRACT The Joggins Fossil Cliffs UNESCO World Heritage Site is a Carboniferous coastal section along the shores of the Cumberland Basin, an extension of Chignecto Bay, itself an arm of the Bay of Fundy, with excellent preservation of biota preserved in their environmental context. The Cliffs provide insight into the Late Carboniferous (Pennsylvanian) world, the most important interval in Earth’s past for the formation of coal. The site has had a long history of scientific research and, while there have been well over 100 publications in over 150 years of research at the Cliffs, discoveries continue and critical questions remain. Recent research (post-1950) falls under one of three categories: general geol- ogy; paleobiology; and paleoenvironmental reconstruction, and provides a context for future work at the site. While recent research has made large strides in our understanding of the Late Carboniferous, many questions remain to be studied and resolved, and interest in addressing these issues is clearly not waning. Within the World Heritage Site, we suggest that the uppermost formations (Springhill Mines and Ragged Reef), paleosols, floral and trace fossil tax- onomy, and microevolutionary patterns are among the most promising areas for future study. RÉSUMÉ Le site du patrimoine mondial de l’UNESCO des falaises fossilifères de Joggins est situé sur une partie du littoral qui date du Carbonifère, sur les rives du bassin de Cumberland, qui est une prolongation de la baie de Chignecto, elle-même un bras de la baie de Fundy.

Abstract: The early vascular plants in the genus Selaginella, which is the sole genus of the Selaginel- laceae family, have an important place in evolutionary history, along with ferns, as such plants are valuable resources for deciphering plant evolution. In this study, we sequenced and assembled the plastid genome (plastome) sequences of two Selaginella tamariscina individuals, as well as Se- laginella stauntoniana and Selaginella involvens. Unlike the inverted repeat (IR) structures typically found in plant plastomes, Selaginella species had direct repeat (DR) structures, which were confirmed by Oxford Nanopore long-read sequence assembly.

Mohr, is a circumboreal, early seral, herbaceous facultative wetland species that occurs along streambanks, lake shores and in wetlands across the northern United States, Canada, and Alaska (USDA NRCS 2001; NatureServe 2001). Disjunct, isolated occurrences of variegated scouring rush in South Dakota, Utah, and Colorado may be relicts from the last Pleistocene glaciations. In Black Hills National Forest, variegated scouring rush is known only from Beaver Gulch in the Bear/Beaver Gulch Botanical Area. As a regional disjunct, boreal species, the Black Hills population is inherently less secure than populations in the core range of the species and may not be able to persist under warmer, drier climatic conditions in Black Hills National Forest. There do not appear to be any immediate risks to the currently known locations of the species, but their small populations and limited microsite habitats may make the species vulnerable to random stochastic events and human-caused disturbances.
