Buzzle – Zoology Terms – Glossary of Biology Terms and Definitions http://www.buzzle.com/articles/biology-terms-glossary-of-biology-terms-and- definitions.html#ZoologyGlossary Biology is the branch of science concerned with the study of life: structure, growth, functioning and evolution of living things. This discipline of science comprises three sub-disciplines that are botany (study of plants), Zoology (study of animals) and Microbiology (study of microorganisms). This vast subject of science involves the usage of myriads of biology terms, which are essential to be comprehended correctly. People involved in the science field encounter innumerable jargons during their study, research or work. Moreover, since science is a part of everybody's life, it is something that is important to all individuals. A Abdomen: Abdomen in mammals is the portion of the body which is located below the rib cage, and in arthropods below the thorax. It is the cavity that contains stomach, intestines, etc. Abscission: Abscission is a process of shedding or separating part of an organism from the rest of it. Common examples are that of, plant parts like leaves, fruits, flowers and bark being separated from the plant. Accidental: Accidental refers to the occurrences or existence of all those species that would not be found in a particular region under normal circumstances. Acclimation: Acclimation refers to the morphological and/or physiological changes experienced by various organisms to adapt or accustom themselves to a new climate or environment. Active Transport: The movement of cellular substances like ions or molecules by traveling across the membrane, towards a higher level of concentration while consuming energy. -

RED ALGAE · RHODOPHYTA Rhodophyta Are Cosmopolitan, Found from the Artic to the Tropics
RED ALGAE · RHODOPHYTA Rhodophyta are cosmopolitan, found from the artic to the tropics. Although they grow in both marine and fresh water, 98% of the 6,500 species of red algae are marine. Most of these species occur in the tropics and sub-tropics, though the greatest number of species is temperate. Along the California coast, the species of red algae far outnumber the species of green and brown algae. In temperate regions such as California, red algae are common in the intertidal zone. In the tropics, however, they are mostly subtidal, growing as epiphytes on seagrasses, within the crevices of rock and coral reefs, or occasionally on dead coral or sand. In some tropical waters, red algae can be found as deep as 200 meters. Because of their unique accessory pigments (phycobiliproteins), the red algae are able to harvest the blue light that reaches deeper waters. Red algae are important economically in many parts of the world. For example, in Japan, the cultivation of Pyropia is a multibillion-dollar industry, used for nori and other algal products. Rhodophyta also provide valuable “gums” or colloidal agents for industrial and food applications. Two extremely important phycocolloids are agar (and the derivative agarose) and carrageenan. The Rhodophyta are the only algae which have “pit plugs” between cells in multicellular thalli. Though their true function is debated, pit plugs are thought to provide stability to the thallus. Also, the red algae are unique in that they have no flagellated stages, which enhance reproduction in other algae. Instead, red algae has a complex life cycle, with three distinct stages. -
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). -

Abstract: The main problem in increasing the production of seaweed cultivation of Kappaphycus alvarezii is the availability of quality seeds. One of the causes is because the seeds are susceptible to infectious diseases. Tissue culture is one of the techniques to produce Specific Pathogen and Epiphyte Free /SPE Nevertheless, the presence or absence of contamination needs to be analyzed to determine the cause of contamination,, morphology of contaminating organisms, and changes of morphological cell of tissue culture which can be used to prevent contamination during the next tissue culture and cultivation at the sea. Based on the results, it could be revealed that the occurring contamination caused by bacteria and fungi as well as caused by the less sterill culture process. Thallus morphology affected by the disease has slower growth. There were also black spots, cotton-like substance as contaminated fungi (Saprolegnia sp and phytopthora), and the fading of green and slimy pigment as bacteria contamination. In addition, the morpology of ill seaweed cells has smaller cells and shrinked tissue compared to the healthy ones with their bigger cells and no shrinkage. 1 INTRODUCTION not specifically examine occuring contamination and identify the contaminant species.

However, many current trade names do not reflect the evolutionary species and updated taxonomy, this is especially the case for eucheumatoid seaweeds that are highly variable in morphology and pigmentation. Genetic variation is also not known for the cultivated eucheumatoids in Indonesia. Therefore, this study aimed to determine the species and the level of genetic variation within species of cultivated eucheumatoids from various farms across Indonesia, spanning 150-1500 km, using the DNA barcoding method. Samples of seaweed were randomly collected at 14 farmed locations between April 2017 and May 2018. For this study the 5- prime end (~ 600 bp) of the mitochondrial-encoded cytochrome oxidase subunit one (COI) was amplified and sequenced. -

Invasive Alien Plants an Ecological Appraisal for the Indian Subcontinent
Invasive Alien Plants An Ecological Appraisal for the Indian Subcontinent EDITED BY I.R. BHATT, J.S. SINGH, S.P. SINGH, R.S. TRIPATHI AND R.K. KOHL! 019eas Invasive Alien Plants An Ecological Appraisal for the Indian Subcontinent FSC ...wesc.org MIX Paper from responsible sources `FSC C013604 CABI INVASIVE SPECIES SERIES Invasive species are plants, animals or microorganisms not native to an ecosystem, whose introduction has threatened biodiversity, food security, health or economic development. Many ecosystems are affected by invasive species and they pose one of the biggest threats to biodiversity worldwide. Globalization through increased trade, transport, travel and tour- ism will inevitably increase the intentional or accidental introduction of organisms to new environments, and it is widely predicted that climate change will further increase the threat posed by invasive species. To help control and mitigate the effects of invasive species, scien- tists need access to information that not only provides an overview of and background to the field, but also keeps them up to date with the latest research findings. This series addresses all topics relating to invasive species, including biosecurity surveil- lance, mapping and modelling, economics of invasive species and species interactions in plant invasions. Aimed at researchers, upper-level students and policy makers, titles in the series provide international coverage of topics related to invasive species, including both a synthesis of facts and discussions of future research perspectives and possible solutions.
