IPNI - International Plant Names Index Natural Perspective: Animal Kingdom The Animal Kingdom is at once the Kingdom most and least familiar to us. Almost all of the animals we commonly think of -- mammals, fish, and birds -- belong to a single subgroup within one of the 33 Phyla comprising the Animal Kingdom. On the other hand, over 100,000 species in some 25 animal phyla -- mostly small worms -- are so unfamiliar that they are virtually unknown to non-scientists. The same goes for several hundred thousand tiny insect-like species populating the Arthropoda phylum. All told, around 800,000 species have been identified in the Animal Kingdom -- most of them in the Arthropod phylum. Spinal Cords (Chordata) All animals having a spine, including fish, mammals, birds, reptiles, amphibians, sharks, and eels are grouped into Chordata. Because these animals are so familiar to us, biologists have come up with elaborate classification schemes including subphyla, superclasses, infraorders, and the like. Joint-Legs (Arthropoda) Soft Bodies = Mollusks (Mollusca)
Plant List Taxonomy Phylogeny Compadre-Plant trait database Botanists at Trinity College Dublin have launched a database with information that documents significant ‘life events’ for nearly 600 plant species across the globe. They clubbed together with like-minded individuals working across five different continents to compile the huge database of plant life histories, for which data have been gathered over a near 50-year span. At a time in which climate change and increasing human populations are rapidly re-shaping plant distributions, the researchers hope their COMPADRE Plant Matrix database will foster collaborations between scientists and allow them to better answer questions such as how we can conserve the species that are critical for ecosystem services, and which may provide food for billions. The botanists have just published an article in the prestigious international, peer-reviewed publication Journal of Ecology that describes the database. We rely on plants for some of our most basic needs like food, shelter and clothing. e!
Untitled 1 Useful Reading Campbell, Biology 6th Ed - Chapters 32 & 33, pgs 633-655, 661-662 Campbell, Biology 7th Ed - Chapter 32 & 33, pgs 626-650, 655-626 Vocabulary Symmetry – general, structured body plan. See radial and bilateral symmetry below. Coelom – fluid-filled body cavity surrounded by mesoderm-derived tissue. Diploblastic – having only two layers of cells during development: the endoderm and ectoderm. Triploblastic – having three layers of cells during development: the endoderm, ectoderm, and mesoderm. Heterotroph – an organism which gets its energy by ingesting food. Hermaphrodite – an individual which can produce both eggs and sperm. Classification In Kingdom Animalia, all taxa are eukaryotic and lack cell walls, multicellular, and generally heterotrophic. The traditional phylogeny is shown below. Presence / absence of true tissues Type of body symmetry Presence / absence of body cavity (coelom) Pattern of coelom development (acoelomate, pseudocoelomate or true coelomate) 1. 2. A. B.
Inside Wood The InsideWood project integrates wood anatomical information from the literature and original observations into an internet-accessible database useful for research and teaching. The InsideWood database contains brief descriptions of fossil and modern woody dicots (hardwoods) from more than 200 plant families, and is searchable by an interactive, multiple-entry key. This wood anatomy web site has over 40,000 images showing anatomical details. Note: Gymnosperm woods (softwoods) are not included. Become a fan of InsideWood on facebook to get information on additions to InsideWood, and occasional comments on how-to-use the website. Also on Twitter The Facebook photo albums listed below have slide sets with background information on InsideWood, including hints and cautions about searching the IW database. "About InsideWood" with information on source of the data and the images, how to export descriptions, caveats about database content. Support InsideWood by buying the "2017.
Morphobank.org - Homologies Global Genome Biodiversity Network A Collaborative Effort to Cryo-preserve and Provide Access to Genomic Samples from Across the Tree of Life The Global Genome Biodiversity Network (GGBN) is a global network of well-managed collections of genomic tissue samples from across the Tree of Life, benefiting society through biodiversity research, development and conservation. This network will foster collaborations among repositories of molecular biodiversity in order to ensure quality standards, improve best practices, secure interoperability, and harmonize exchange of material in accordance with national and international legislation and conventions. Goals Provide genome-quality samples from across the Tree of Life for research, training, and development, thereby contributing to the conservation of global genetic diversity for generations to come.
Famine Foods Website by Robert L. Freedman Orinda, California U.S.A. My interest in the study of famine food-plants began in 1966 when I was an undergraduate student in the anthropology department of the University of Arizona. In my last semester, I wrote a term paper on Native American food preparation techniques, for Professor Bernard Fontana's class, "History of the Indians of North America." This research became the catalyst for an interest in the socio-anthropological aspects of human food habits, which lasted for the next fifteen years. After exhaustively searching the ethnographic literature in the University of Arizona's anthropology and main libraries, I had 103 typewritten pages of food preparation information representing several dozen Native American and Native Canadian tribes. There is no documentation indicating when famine plants were first used. Between the research of those noteworthy Chinese botanists and the Twentieth Century, only two works stand out: PRATHER (1596) and PARMENTIER(1781).
IFPNI: Internatioal fossil plant names index Global registry of scientific names of fossil organisms covered by the International Code of Nomenclature for Algae, Fungi, and Plants (formerly International Code of Botanical Nomenclature) and International Code of Zoological Nomenclature Algae Cyanobacteria and allied prokaryotic forms Fungi Plants Problematica Protists related to algal phyla (‘ambiregnal organisms’) IFPNI provides an authoritative online, open-access, community-generated registry of fossil plant nomenclature as a service to the global scientific community. Dynamic data base documents all nomenclatural novelties (new scientific names of extinct organisms) and associated data, including registration of the scientific publications containing nomenclatural acts and authors generated taxonomic literature in palaeobotany and palaeontology in general, and allied disciplines.
