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. -

Marine microorganism will be an opportunity to further understand ourselves and to seek for new Ois the host of ocean in all ages. We should learn from them humbly. methods of fighting old infections. Marine microorganism is tightly bond with human during the history of evolution and nowadays’ environment pollution. Along with industrial revolution, our marine ecosystem suffered serious pollutions. Microplastics are tiny plastic particles (<5 mm) (Figure 1B), Although the topic is still in debate, life is probably originated from which poison marine lives. Because these microplastics are very hard to be submarine in hydrothermal vent systems (1). In the journey of evolution, our degraded, it is predicted that there will be more microplastics than fish in biosphere was completely dominated by microbes for a very long time (Figure ocean by the year 2050 (7). Since marine sediments are considered as the sink 1A). Human being evolves with those microorganisms. Consequently, of microplastics and marine microbes are key dwellers of marine sediments, the influences of microorganisms can be found in all aspects of human more attention should be paid on the interactions between microplastics biology. More than 65% of our genes originated with bacteria, archaea, and and marine microbes. Actually, a call for this has been published in 2011 unicellular eukaryotes, including those genes responsible for host-microbe (8). -

The examination will be conducted in English. Faculty examiner: Professor Matthias Horn (Department of Microbial Ecology and Ecosystem Science, Division of Microbial Ecology). Abstract García-Montaner, A. 2020. Genome evolution of a bee-associated bacterium. Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1953. 80 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-513-0986-6. The use of large-scale comparative genomics allows us to explore the genetic diversity and mechanisms of evolution of related organisms. This thesis has focused on the application of such approaches to study Lactobacillus kunkeei, a bacterial inhabitant of the honeybee gut. We produced 102 novel complete genomes from L. kunkeei, which were used in four large comparative studies. In the first study, 41 bacterial strains were isolated from the crop of honeybees whose populations were geographically isolated. Their genome sequences revealed differences in gene contents, including the mobilome, which were mostly phylogroup- specific. However, differences in strain diversity and co-occurrence between both locations were observed. In the second study, we obtained 61 bacterial isolates from neighboring hives at different timepoints during the summer. -
Phytoplankton As Key Mediators of the Biological Carbon Pump: Their Responses to a Changing Climate
sustainability Review Phytoplankton as Key Mediators of the Biological Carbon Pump: Their Responses to a Changing Climate Samarpita Basu * ID and Katherine R. M. Mackey Earth System Science, University of California Irvine, Irvine, CA 92697, USA; [email protected] * Correspondence: [email protected] Received: 7 January 2018; Accepted: 12 March 2018; Published: 19 March 2018 Abstract: The world’s oceans are a major sink for atmospheric carbon dioxide (CO2). The biological carbon pump plays a vital role in the net transfer of CO2 from the atmosphere to the oceans and then to the sediments, subsequently maintaining atmospheric CO2 at significantly lower levels than would be the case if it did not exist. The efficiency of the biological pump is a function of phytoplankton physiology and community structure, which are in turn governed by the physical and chemical conditions of the ocean. However, only a few studies have focused on the importance of phytoplankton community structure to the biological pump. Because global change is expected to influence carbon and nutrient availability, temperature and light (via stratification), an improved understanding of how phytoplankton community size structure will respond in the future is required to gain insight into the biological pump and the ability of the ocean to act as a long-term sink for atmospheric CO2. This review article aims to explore the potential impacts of predicted changes in global temperature and the carbonate system on phytoplankton cell size, species and elemental composition, so as to shed light on the ability of the biological pump to sequester carbon in the future ocean. -
