Chapter 6 marine microbes
Marine microbes play many roles in marine ecosystems and include viruses, single-celled organisms, and fungi. Phytoplankton such as diatoms and dinoflagellates contribute to primary productivity through photosynthesis, while zooplankton such as foraminifera feed on other organisms. Diatoms have glass cell walls with geometric patterns and reproduce asexually. Dinoflagellates have two flagella, come in a variety of shapes, and can reproduce sexually or asexually. Foraminifera use pseudopods to move and feed and have shells, reproducing asexually or sexually.
The 5 kingdoms
The document discusses the 5 kingdoms of classification: plants, fungi, animals, bacteria, and protists. It provides details about the main groups within each kingdom. For plants it describes vascular and non-vascular plants as well as the main parts of flowering plants. Fungi are described as not containing chlorophyll and decomposing dead materials. The animal kingdom is divided into vertebrates and invertebrates. Bacteria are microscopic and found everywhere. Protists include protozoa and algae, with amoebas being the simplest protist.
microbial loop
This document provides an overview of the microbial loop in marine ecosystems. It discusses how bacteria consume dissolved organic matter released by phytoplankton and protozoans. These bacteria are then consumed by protozoans like flagellates and ciliates, recycling nutrients and carbon back into the food web. Approximately 60% of energy in marine food chains is estimated to pass through this microbial loop. The loop links dissolved organic matter to microbes and micrograzers, and is crucial to ecosystem function by transferring carbon and nutrients between trophic levels.

Algae
This document provides information about algae, including their definition, characteristics, habitats, and classification. Some key points:
i. Algae are chlorophyll-bearing microorganisms that can be unicellular or multicellular. They are mostly aquatic but also occur in soils, rocks, snow, and other habitats.
ii. Algae have simple plant-like bodies but lack vascular tissues and true roots/leaves. Reproduction occurs through mitosis or meiosis rather than embryogenesis.
iii. Algae are classified into 11 major groups, with the first four - cyanobacteria, green algae, diatoms, and yellow-green algae - commonly found in soils. Blue-green al

(12) Function Photosynthesis Treating wastewater Anaerobic digestion Mold Type of organisms b) The Tempe Town Lake, like a lot of water bodies (e.g. Lake Erie), has green water. What causes the color? What are the nutrients (elements) behind this phenomenon? (8)
Solution
Answer
2, (a) Photosynthesis - Macrophyte( plants) , Algae
Treating waste water - Bacteria
Anerobic digestion - Fungi, protozoa
Mold - Fungi
b) Lake color can tell you many things about the water body (e.g., including nutrient load, algal growth, and water quality) and also about the surrounding landscape.Green water lakes commonly have high concentrations of chlorophyll-containing algae which can give water a green color. That is Algae which gets formed on stagnant water. Algae needs nutrients, sunlight and water to form. A high concentration of Algae indicates water is rich in nutrients primarily phosphorus.
Green lakes are often eutrophic and typically contain more harmful algal blooms than other types of lakes. Activities such as farming or septic system failure can increase the green color of lakes through nutrient inputs which act as a fertilizer for algae. The high productivity of green lakes usually enables them to support more fish, but the poor water quality conditions can depress dissolved oxygen levels in hot summer months; these conditions can cause fish kills where oxygen drops too low for fish to survive.( Algal overgrowth due to eutrophication - caused by fertilizer runoff from fields and lawns.)
Nutrients causing eutrophication
The most common nutrients causing eutrophication are nitrogen and phosphorus . The main source of nitrogen pollutants is run-off from agricultural land, whereas most phosphorus pollution comes from households and industry, including phosphorus-based detergents. These nutrients enter aquatic ecosystems via the air, surface water or groundwater. Most of the commercially fixed nitrogen and mined phosphorus goes into production of fertilizer. The rising demand for fertilizer has come from the need to meet the nutritional demands of our rapidly expanding human population.

lichen1.ppt
Lichens are a symbiotic partnership between a fungus and a photosynthetic symbiont such as an alga or cyanobacterium. This relationship results in a stable structure called a thallus. Lichens can grow in a wide range of habitats and withstand environmental extremes. They are primary colonizers and play an important role in weathering rock and forming soil. Lichens are very sensitive to air pollution. Their fungal partners are typically ascomycetes which produce spores. Lichens reproduce through vegetative fragmentation or sexually through spores. They exist in crustose, foliose, fruticose or other forms depending on their structure and growth.

Algae introduction
The term "algae" covers many different organisms capable of producing oxygen through photosynthesis (the process of harvesting light energy from the sun to generate carbohydrates).
Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis. Certain algae are familiar to most people; for instance, seaweeds (such as kelp or phytoplankton), pond scum or the algal blooms in lakes. However, there exists a vast and varied world of algae that are not only helpful to us, but are critical to our existence.

PDC+++ Module 3 Class 1 The Soil
We could say that the destructo-culture, based on industrialized agriculture, carries a basic dysfunction, which is to see the soil as an inanimate thing, a resource to be exploited, & even something that can be seen as 'property' of human beings.
This paradigm has to change because it is at the base of great injustices & of the destruction of the most important base for life on Earth.
In this class we meet the soil as a living being, an organism of enormous complexity & importance, studying how it works in detail, from the microscopic to the global level.
To know soil intimately is fundamental for any sustainable design & to have a direct & vital relationship with this great organism helps us re-connect, physically as well as emotionally, with the Planet.
Soil as a natural resource
Soil is considered to be the “skin of the earth". Soil is capable of supporting plant life and all life on earth. Soils are complex mixtures of 5 major components. The importance of soils as natural resource are highlighted in this module.
Man and his Environment
This document discusses various types of ecosystems and their components. It begins by defining an ecosystem as a biological community of interacting organisms and their physical environment. It then describes three major classes of ecosystems: freshwater, terrestrial, and oceanic. Each section provides details on the characteristics and examples of ecosystems within these classes. The document also discusses abiotic and biotic components of ecosystems, including producers, consumers, decomposers, and food chains/webs. It focuses specifically on carbon, nitrogen, phosphorus, and water cycles, as well as symbiotic, parasitic, predatory, and competitive relationships between organisms within ecosystems.
Vermiculture techniques and advantages
This document provides information about different types of composting, including bin composting, tumbler composting, sheet composting, anaerobic composting, and vermicomposting. It discusses materials that can and cannot be composted, how to determine when compost is finished, and the benefits of various composting methods. Vermicomposting, or composting with worms, is described as harnessing worms to convert organic materials into usable compost and fertilizer, with earthworms improving soil structure, aeration, moisture retention, and nutrient content.

Observations
1
Water clean, clear and no smell
2
Water remains clear, veggie oil floats on top of water its light yellow on top and clear on bottom, no smell
3
Looks a little foggy and smell like vinegar
4
Water turned light blue and smell like laundry detergent
5
Turned a little dark but no smell
6
Water turned darker brown, but no smell.
7
Water turned a darker brown, smells like vinegar and all water came through the soil
8
Water turned very dark, all water came through soil, still smell like laundry detergent
1. What effects did each of the contaminants have on the water in the experiment? Use Table 1 for reference.
Answer = Some of the water remained clear with no smell. When water was mixed with oil the oil floated to top and water remained clear at the bottom. Water looked foggy when mixed with vinegar and smelled like vinegar as well.
2. What kinds of human activities could cause oil, acids, and detergents to contaminate the water supply?
Answer = Oil spills can contaminate nearby water sources Improperly disposing oil, acids and detergents can also cause water contamination. Houses septic tank, and pipes not properly installed fan cause nearby water contamination.
3. What are the differences in color, smell, visibility, etc. between the “contaminated” water and the “treated” water?
Answer = The contaminated water is dark, dirty color and the treated water is a light brown clearer than contaminated water. I wasn’t able to smell anything from contaminated or treated water.
4. From the introduction to Lab 2, you know that there are typically five steps involved in the water treatment process. Identify the processes (e.g., coagulation) that were used in this lab and describe how they were performed.
Answer = First thing I did to purifying the contaminated was water was adding the 10grams of alum mixing it with water, which is call coagulation. This caused the dirt to clump up and sink to bottom and separated from the water that was separated from the water. Secondly was sedimentation, when I poured the water that was separated from the dirt into the filter and the marked beginning of the filtration process. While the water was filtering, the water also slowed down while trying to pass through the filter which was made of charcoal, gravel and sand. The filter worked because the water was cleaner in the beaker below the funnel. Lastly was the purifying, a sma ...
Soil as microbial habitat
The document discusses microbial ecology and the composition of soil as an environment for microorganisms. It notes that soil is a complex ecosystem containing a vast array of microbes, plants, and animals. The lithosphere is composed of weathered rock, humus, and nutrients. The rhizosphere around plant roots contains associated bacteria, fungi, and protozoa. Microbes play important roles in soil, including nutrient provision, decomposition, nitrogen fixation, and preventing pathogens. Bacteria, actinomycetes, and fungi are the dominant microbial groups in soil and influence processes like nutrient cycling and plant growth.

Better Than A Bag Of Bricks
Presented by Sean Bonner at SCAQMD "Making Sense of Sensors" conference, Sept 2017. Diamond Bar, CA
Safecast has been called "the most successful citizen science project yet." Started in March, 2011 in response to the Fukushima Daiichi Nuclear Powerplant accident, it initially focussed on collecting and publishing independent radiation measurements from affected areas in Japan but quickly achieved global scale. The open Safecast radiation database now contains over 75 million measurements, the largest of it's kind ever. In addition to gaining influence within the IAEA and other corners of the radiation expert community, it has become the subject of research by data analysis and visualization specialists. This presentation will describe key aspects of the Safecast project, its primary principles, and lessons learned that may be of relevance to others seeking to implement similar environmental monitoring projects.
What Safecast does: A quick overview of the Safecast project, and some of the key milestones we’ve passed along the way.
Why open?: Openness is built into every aspect of the Safecast project. Why is this important?
Plan for success: Why it’s important to plan ahead for massive scaling of environmental datasets.
People, not devices: Without an active community, the devices are just chunks of plastic.
Agility: Safecast’s tiny development teams punch way above their weight. How do we do it?
Education is the best communication: People participate because they want to know, and once they do, they want to share it.
On the horizon: We have a few new things in the works.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Ishimaru (Kodomomirai): Why caesium is detected in food; Safecast symposium presentation
- 1. List of main reasons of why radioactive cesium is detected from food A. The detected amount of cesium is proportional to its density in the soil However the contamination amount is different by many reasons. B. High level of contamination by concentrated radioactive materials When the contamination is highly concentrated, there are higher possibility of food high level contamination as well 1. Directly exposed to radioactive materials (especially absorbed by surface in March 2011) Example: Citrus, tea leaves and wheat cropped in 2011 2. Seeds and leaves of perennial plants (especially evergreen trees) etc. Example: Plums, citrus, tea leaves, chestnuts and kiwis 3. Foods that are high in potassium Example: bamboo shoot, tea leaves, rice bran, soya beans, herb,edible wild plants and so on. 4. Foods that grow in non-clay soil Example: all kinds of mushrooms and buckwheat (plant in Kuroboku-soil) 5. Foods that grow in acid soil Example: buckwheat, blue berries that grow in peat moss 6. Exchange between ammonium and cesium (beans’ root nodule bacteria, ammonium fertilizer) Example: Soya beans 7. Foods that grow inside soil (Many of them are not contaminated, or low contaminated) Example: Sweet potatoes 8. Foods that grow in water or mad (example:Rice that grew in water which contained 0.1Bq/L was contaminated as 76Bq/kg) Example: rice, lotus root 9. Foods that have shallow roots (cesium have higher contamination in the surface layer) Example: edible wild plants, herbs 10. Wild plants and animals that eat them Example: edible wild plants, mushrooms, moss, deer and wild pig 11．Foods that grow in immature compost Example: bamboo shoot 12.Seafood inhabit in the bottom of coastal area, they make an excursion in highly contaminated areas and also they are on top of the food chain Example: madara cod ,flatfish and so on 13.Freshwater fish contains minerals therefore they contain cesium easily Example: most kinds of freshwater fish (This document was made by KODOMOMIRAI Radiation Measuring Center)
