Mnemonic Memory Taxonomy
MNEMONIC MEMORY TAXONOMY Overview: In this lesson, students determine proper classification of organisms according to taxonomic levels, explore characteristics that determine classification, and create methods to recall ordered taxonomic terminology. Objectives: The student will: • describe the use and function of a taxonomy, specifically to order and classify living organisms; and • identify and list taxonomic levels of biological classification. Targeted Alaska Grade Level Expectations: Science [7] SC2.2 The student demonstrates an understanding of the structure, function, behavior, development, life cycles, and diversity of living organisms by identifying the seven levels of classification of organisms. [7] SA1.1 The student demonstrates an understanding of the processes of science by asking questions, predicting, observing, describing, measuring, classifying, makign generalizations, inferring, and communicating. Vocabulary: animalia— one of six kingdoms, including most living things that are able to move and digest food internally plantae –one of six kingdoms, including living things that generally manufacture their own food through the use of photosynthesis fungi – one of six kingdoms, mostly living things that are nonmobile and assist in the decomposition process, including yeasts, molds, and mushrooms binomial nomenclature – a scientific naming system that gives a unique name (“scientific name”) to each species, using organisms’ genus and species as its two parts (e.g., “Homo sapiens” for humans) class – a taxonomic rank below -

Alyssum) and the Correct Name of the Goldentuft Alyssum
ARNOLDIA VE 1 A continuation of the BULLETIN OF POPULAR INFORMATION of the Arnold Arboretum, Harvard University VOLUME 26 JUNE 17, 1966 NUMBERS 6-7 ORNAMENTAL MADWORTS (ALYSSUM) AND THE CORRECT NAME OF THE GOLDENTUFT ALYSSUM of the standard horticultural reference works list the "Madworts" as MANYa group of annuals, biennials, perennials or subshrubs in the family Cru- ciferae, which with the exception of a few species, including the goldentuft mad- wort, are not widely cultivated. The purposes of this article are twofold. First, to inform interested gardeners, horticulturists and plantsmen that this exception, with a number of cultivars, does not belong to the genus Alyssum, but because of certain critical and technical characters, should be placed in the genus Aurinia of the same family. The second goal is to emphasize that many species of the "true" .~lyssum are notable ornamentals and merit greater popularity and cul- tivation. The genus Alyssum (now containing approximately one hundred and ninety species) was described by Linnaeus in 1753 and based on A. montanum, a wide- spread European species which is cultivated to a limited extent only. However, as medicinal and ornamental garden plants the genus was known in cultivation as early as 1650. The name Alyssum is of Greek derivation : a meaning not, and lyssa alluding to madness, rage or hydrophobia. Accordingly, the names Mad- wort and Alyssum both refer to the plant’s reputation as an officinal herb. An infu- sion concocted from the leaves and flowers was reputed to have been administered as a specific antidote against madness or the bite of a rabid dog. -
Botanical Nomenclature: Concept, History of Botanical Nomenclature
Module – 15; Content writer: AvishekBhattacharjee Module 15: Botanical Nomenclature: Concept, history of botanical nomenclature (local and scientific) and its advantages, formation of code. Content writer: Dr.AvishekBhattacharjee, Central National Herbarium, Botanical Survey of India, P.O. – B. Garden, Howrah – 711 103. Module – 15; Content writer: AvishekBhattacharjee Botanical Nomenclature:Concept – A name is a handle by which a mental image is passed. Names are just labels we use to ensure we are understood when we communicate. Nomenclature is a mechanism for unambiguous communication about the elements of taxonomy. Botanical Nomenclature, i.e. naming of plants is that part of plant systematics dealing with application of scientific names to plants according to some set rules. It is related to, but distinct from taxonomy. A botanical name is a unique identifier to which information of a taxon can be attached, thus enabling the movement of data across languages, scientific disciplines, and electronic retrieval systems. A plant’s name permits ready summarization of information content of the taxon in a nested framework. A systemofnamingplantsforscientificcommunicationmustbe international inscope,andmustprovideconsistencyintheapplicationof names.Itmustalsobeacceptedbymost,ifnotall,membersofthe scientific community. These criteria led, almost inevitably, to International Botanical Congresses (IBCs) being the venue at which agreement on a system of scientific nomenclature for plants was sought. The IBCs led to publication of different ‘Codes’ which embodied the rules and regulations of botanical nomenclature and the decisions taken during these Congresses. Advantages ofBotanical Nomenclature: Though a common name may be much easier to remember, there are several good reasons to use botanical names for plant identification. Common names are not unique to a specific plant. -
Biology Assessment Plan Spring 2019
Biological Sciences Department 1 Biology Assessment Plan Spring 2019 Task: Revise the Biology Program Assessment plans with the goal of developing a sustainable continuous improvement plan. In order to revise the program assessment plan, we have been asked by the university assessment committee to revise our Students Learning Outcomes (SLOs) and Program Learning Outcomes (PLOs). Proposed revisions Approach: A large community of biology educators have converged on a set of core biological concepts with five core concepts that all biology majors should master by graduation, namely 1) evolution; 2) structure and function; 3) information flow, exchange, and storage; 4) pathways and transformations of energy and matter; and (5) systems (Vision and Change, AAAS, 2011). Aligning our student learning and program goals with Vision and Change (V&C) provides many advantages. For example, the V&C community has recently published a programmatic assessment to measure student understanding of vision and change core concepts across general biology programs (Couch et al. 2019). They have also carefully outlined student learning conceptual elements (see Appendix A). Using the proposed assessment will allow us to compare our student learning profiles to those of similar institutions across the country. Revised Student Learning Objectives SLO 1. Students will demonstrate an understanding of core concepts spanning scales from molecules to ecosystems, by analyzing biological scenarios and data from scientific studies. Students will correctly identify and explain the core biological concepts involved relative to: biological evolution, structure and function, information flow, exchange, and storage, the pathways and transformations of energy and matter, and biological systems. More detailed statements of the conceptual elements students need to master are presented in appendix A. -
Guide to Plant Collection and Identification
GUIDE TO PLANT COLLECTION AND IDENTIFICATION by Jane M. Bowles PhD Originally prepared for a workshop in Plant Identification for the Ministry of Natural Resources in 1982. Edited and revised for the UWO Herbarium Workshop in Plant Collection and Identification, 2004 © Jane M. Bowles, 2004 -0- CHAPTER 1 THE NAMES OF PLANTS The history of plant nomenclature: Humans have always had a need to classify objects in the world about them. It is the only means they have of acquiring and passing on knowledge. The need to recognize and describe plants has always been especially important because of their use for food and medicinal purposes. The commonest, showiest or most useful plants were given common names, but usually these names varied from country to country and often from district to district. Scholars and herbalists knew the plants by a long, descriptive, Latin sentence. For example Cladonia rangiferina, the common "Reindeer Moss", was described as Muscus coralloides perforatum (The perforated, coral-like moss). Not only was this system unwieldy, but it too varied from user to user and with the use of the plant. In the late 16th century, Casper Bauhin devised a system of using just two names for each plant, but it was not universally adopted until the Swedish naturalist, Carl Linnaeus (1707-1778) set about methodically classifying and naming the whole of the natural world. The names of plants: In 1753, Linnaeus published his "Species Plantarum". The modern names of nearly all plants date from this work or obey the conventions laid down in it. The scientific name for an organism consists of two words: i) the genus or generic name, ii) the specific epithet. -
Receptor-Like Kinases from Arabidopsis Form a Monophyletic Gene Family Related to Animal Receptor Kinases
Receptor-like kinases from Arabidopsis form a monophyletic gene family related to animal receptor kinases Shin-Han Shiu and Anthony B.

Meyerowitz, California Institute of Technology, Pasadena, CA, and approved July 6, 2001 (received for review March 22, 2001) Plant receptor-like kinases (RLKs) are proteins with a predicted tionary relationship between the RTKs and RLKs within the signal sequence, single transmembrane region, and cytoplasmic recognized superfamily of related eukaryotic serine͞threonine͞ kinase domain.

Since T. acetoethylicus is the type species of Thennobacteroides, its removal invalidates the genus. As a consequence, the remaining species Thennobacteroides proteolyticus is proposed as the type species of the new genus Coprothennobacter gen. nov., as Coprothennobacter proteolyticus comb. nov.

Re-Description of the Sauropod Dinosaur Amanzia (“Ornithopsis
Schwarz et al. Swiss J Geosci (2020) 113:2 https://doi.org/10.1186/s00015-020-00355-5 Swiss Journal of Geosciences ORIGINAL PAPER Open Access Re-description of the sauropod dinosaur Amanzia (“Ornithopsis/Cetiosauriscus”) greppini n. gen. and other vertebrate remains from the Kimmeridgian (Late Jurassic) Reuchenette Formation of Moutier, Switzerland Daniela Schwarz1* , Philip D. Mannion2 , Oliver Wings3 and Christian A. Meyer4 Abstract Dinosaur remains were discovered in the 1860’s in the Kimmeridgian (Late Jurassic) Reuchenette Formation of Moutier, northwestern Switzerland. In the 1920’s, these were identifed as a new species of sauropod, Ornithopsis greppini, before being reclassifed as a species of Cetiosauriscus (C. greppini), otherwise known from the type species (C. stewarti) from the late Middle Jurassic (Callovian) of the UK. The syntype of “C. greppini” consists of skeletal elements from all body regions, and at least four individuals of diferent sizes can be distinguished. Here we fully re-describe this material, and re-evaluate its taxonomy and systematic placement. The Moutier locality also yielded a theropod tooth, and fragmen- tary cranial and vertebral remains of a crocodylomorph, also re-described here. “C.” greppini is a small-sized (not more than 10 m long) non-neosauropod eusauropod. Cetiosauriscus stewarti and “C.” greppini difer from each other in: (1) size; (2) the neural spine morphology and diapophyseal laminae of the anterior caudal vertebrae; (3) the length-to-height proportion in the middle caudal vertebrae; (4) the presence or absence of ridges and crests on the middle caudal cen- tra; and (5) the shape and proportions of the coracoid, humerus, and femur. -
