...happened around 542 million years ago, of most major animal phyla, as demonstrated in the fossil record. 1. In the report of rates of Phenotypic and Genomic Evolution during the Cambrian Explosion, these seemingly impossibly fast rates of evolution implied by this Cambrian explosion have long been exploited by opponents of evolution. Moreover, the exact speed and nature of this grand adaptive radiation remain debated, and how to inferred from. Phenotypic differences among living organisms are addressed. Basically, the journal supposes that "Darwin's evolutionary theory" is correct first. Another hypothesis the report mentioned is that Cambrian radiation is perfectly consistent with Darwin's theory of evolution. The hypothesis is also assuming an Ediacaran origin for arthropods, phenotypic evolution was w4 times faster, andmolecular evolution w5.5 times faster, during the Cambrian explosion compared to all subsequent parts of the Phanerozoic. These rapid evolutionary rates are robust to assumptions about the precise age of arthropods(Michael S.Y. Lee, et al., 2013). 2. The research focused on arthropods (insects, crustaceans, arachnids and their relatives), that are the most diverse animal group in both the Cambrian period and present day. This study concerns arthropods, but the results are likely applicable to most of life. 3. In the report, the authors use records of fossils whose age is 515-million-year-old to present. These fossils lived during the Cambrian...

...invertebrates and vertebrates is crucial. Without it our society would be very different, fields like medicine and psychology would be almost nonexistent. To further understand the difference between these organisms it is important to note characteristics both common and uncommon among them, I have in the following paragraph written a synopsis of these differences to reveal what this lab report serves to investigate. Animal classification sorts out similarities and differences between animals as a means of placing animals in groups and then breaking those groups into subgroups. The whole process creates a hierarchy in which the large high-level groups sort out more obvious differences, while the low-level groups deal with more subtle differences. This labeling allows scientists to describe evolutionary relationships, identify shared traits, and highlight unique characteristics through the various levels of animal groups and subgroups. One of the most basic criteria used to sort animals is whether or not they possess a backbone. This single trait places an animal into one of just two groups: the...

Reconstructing Phylogenies • 1859-1950- No coherent empirical methods • 1950-1966- Emergence of Phylogenetic Systematics • Phylogeny by discovery of the order of evolutionary innovation Ribotyping • Fingerprinting or sequencing RNA • Many diseases have unknown causes • However, diseased tissues can be ribotyped. (Wiley Death Fish) • This process involves extracting DNA from diseased tissues and then sequencing the DNA that codes for rRNA. • If a disease agent such as a bacteria is present, then we will get ribosomal DNA sequences from the host (you) and the bacteria (the infection agent). Ribotyping: Phylogeny matching • Once we have the rDNA sequences, we can plug them into a sequence matrix of all life and see where our unknowns appear on the tree of life.

...structure of the earth took place during this time period. The Paleozoic Era is divided into six different subcategories which include: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. Early in the Paleozoic the continents were far apart but moving tectonic plates caused continents to move together into one large continent called Pangaea. Some of the significant geologic events that occurred during the Paleozoic era includes the evolution of a large number of animals, some of which are distant ancestors to modern organisms, between 530 and 520 million years ago. Also during this time period, there was an introduction to animals without backbones (invertebrates). Organisms such as corals, brachiopods, mollusks, and arthropods populated the early and middle parts of the Paleozoic era. A massive extinction event known as “The Great Dying” marked the end of the Paleozoic era. During this mass extinction, as many...

...1.1. INTRODUCTION:- Agriculture is the lynchpin of the Indian economy and contributes 18% to the GDP. Ensuring food security for more than 1.27 billions Indian populations with diminishing cultivable land resource is a herculean task. In the process of achieving the target pesticides play an important role in Indian agriculture. Pesticides, the agrochemicals, are one of the invaluable inputs in sustaining the agricultural production as substantial food production is lost due to insect pests, plant pathogens, weeds etc. However since the green revolution (1966) has been started in India, the application of these chemicals increased more than hundred times and causing tremendous loss to environment and human health. Internationally big effort is made to safe use of chemicals which are reflected in which identified the elements for the sound management of the chemicals. In India Nearly 65% of the workforce derives livelihood from agriculture and are therefore exposed to chemical pesticides (Asian Monitor Resource Centre). The rampant use of pesticides has played havoc with living beings and the environment as these chemicals persist and seep in environment for a long time because of more water solubility, tendency to adsorb to the soil (soil adsorption) and more half-life that is tendency to persistence in the environment. The term pesticide covers a wide range of compounds including insecticides, fungicides, herbicides, rodenticides, molluscicides, nematicides, plant growth...

...Pill Bug Lab Report DESIGN Research Question: Will a pill bug prefer fresh or decomposing tomatoes since both are present in their diet? Background: The Armadillidium vulgare (common pill bug) that we have seen as kids rolling into a ball when disturbed is a crustacea that belongs to an animal group called isopods. Pill bugs are crustaceans that have adapted to terrestrial habitats. According to Koehler (1994), “They are wingless, oval or slightly elongated arthropods about 12 inch in length and slate-gray with body segments resembling armored plates” (p. 1). Pill bugs lack tails and were given the name “rolly-pollies” to further describe their tendency to roll into a tight ball when frightened or in danger. Pill bugs crawl around on their...

...REPORT ON EUROTOWN DISASTER Introduction On the 14 Oct 11 the Municipalities Emergency Preparedness Group was in meeting. At 1000 hrs it was reported that there was a major electrical failure affected the greater part of Eurotown. No initial assumptions were made but the respective service agencies were contacted. At 1200 hrs the situation deteriorated with a serious fires starting in a factory units in Bromley Hill. A Major Incident was declared at 1205 hrs and the ‘Eurotown Emergency Plan’ was activated in accordance with the Civil Contingencies Act 2004. The following actions were undertaken: * Traffic Management plan implemented. * Emergency media plan implemented (and throughout all stages of the incident). * Multi-agency action plan implemented (mutual aid response). * Communication and co-ordination with ‘Tactical Coordination Group. * Impact of power outages on critical infrastructure. * Vulnerable groups such as schools and care homes were contacted. At 1330 hrs the fire had spread to adjacent properties which housed an LPG storage tank and 10 tonnes of chlorine. The risk of explosion and the release of a toxic plume were considered severe and priority was given to evacuating residential and business properties within 500 metres of the site around the LPG storage facility and evacuation of the personnel calculated to be effected by the plume. It was agreed that evacuation of both these groups should be co-ordinated and given equal priority...

...Introduction Zoonotic diseases are infectious diseases which can be transmitted from animals to man. Due to frequent contact and domestication of wildlife animals, zoonotic diseases are increasingly becoming more prevalent. Public parks and gardens are home to abundant populations of birds. One of the most frequent species known to thrive in such areas are feral pigeon (Columba livia). Although there are few reports of disease transmission between pigeons and humans, their close interaction with humans and ability to carry zoonotic pathogens make them a public health risk. In fact, these birds are present at very high densities (2,000 individuals per km2) and can cover a maximum distance of 5.29 km (Dickx et al., 2010). This may result in the increase risk of pathogen transmission among other birds and potentially to humans. Studies have shown that most infected pigeons do not show signs of clinical disease. These birds may therefore pose a public health risk to the human population. Pigeons, like many other bird species, can harbor diseases that can be zoonotic in nature. One of the pathogens most frequently carried by pigeons is Chlamydophila psittaci. C. psittaci is an obligate intracellular bacterium that causes a disease in birds known as Psittacosis or Avian Chlamydiosis. Psittacosis is highly contagious and often causes influenza-like symptoms, severe pneumonia and non-respiratory health problems. Birds can shed this bacterium in the environment when they are...

Navajas (2) (1) French National Institute for Agronomic Research (Institut National de la Recherche Agronomique - INRA), UMR 406 Abeilles et Environment (INRA/UAPV), Laboratoire Biologie et Protection de l’Abeille, Site Agroparc, Domaine Saint-Paul, 84914 Avignon Cedex 9, France (2) French National Institute for Agronomic Research (INRA), UMR CBGP (INRA/IRD/CIRAD/Montpellier SupAgro), Campus International de Baillarguet, CS 30016, 34988 Montferrier-sur-Lez Cedex, France Summary The European honey bee, Apis mellifera, is the most economically valuable pollinator of agricultural crops worldwide. Bees are also crucial in maintaining biodiversity by pollinating numerous plant species whose fertilisation requires an obligatory pollinator. Apis mellifera is a species that has shown great adaptive potential, as it is found almost everywhere in the world and in highly diverse climates. In a context of climate change, the variability of the honey bee’s lifehistory traits as regards temperature and the environment shows that the species possesses such plasticity and genetic variability that this could give rise to the selection of development cycles suited to new environmental conditions. Although we do not know the precise impact of potential environmental changes on honey bees as a result of climate change, there is a large body of data at our...

...occurred from 1960-1990 with the research and discovery of most of the roughly 500 species of obligate marine fungi. Much of said research was conducted from 1980-2000; this 30 year period saw the report of nearly half of the marine fungal species currently known (Jones et al. 2009; Jones, 2011). That being said, marine fungi are vastly understudied and under rated in comparison to marine plants, animals, and other microorganisms; frequently they are omitted or only briefly referenced in marine biodiversity and ecology text books (Jones and Pang, 2012). The cladistics of marine fungi is currently in a state of flux, with new taxa being discovered as molecular techniques such as DNA and RNA analysis via polymerase chain reactions, and gel electrophoresis are implemented (Ald et al 2005). Even though fungus-like organisms such as oomycetes are not fungi, marine mycologists often study them as they perform similar functions, and until recently most had been classified as fungi based on their morphological similarities (Jones, 2011). These fungus-like organisms are eukaryotic, heterotrophic, zoospores, have chitin containing cell walls, and similar life cycles to fungi (Neuhauser et al. 2012). Conventionally terrestrial or freshwater species are also included in the marine fungal group as facultative species; this is due to their active ecological role in the marine, and estuarine environment. Here is broad, but accepted definition for obligate, and facultative marine fungi from...
