Aluminium. Ein Leichtmetall, das schwer wiegt: Gewinnung, by Esra Bozcicek

By Esra Bozcicek

Facharbeit (Schule) aus dem Jahr 2013 im Fachbereich Biologie - Ökologie, word: Sehr intestine, , Sprache: Deutsch, summary: Viele Menschen sind sich nicht bewusst, wie schädlich Aluminium für den eigenen Körper sein kann, da die Hersteller dies den Verbrauchern vorenthalten.

Um diese Leichtigkeit im Umgang mit der Gefahr Aluminium in Frage zu stellen, werde ich mich mit dem Thema in dieser Facharbeit kritisch auseinandersetzen.

Im ersten Kapitel werde ich zunächst einmal klären, was once Aluminium überhaupt ist und wo wir – ob bewusst oder unbewusst – mit diesem konfrontiert werden.

Danach werde ich auf die Herstellung dieses Metalls eingehen, bevor ich die Auswirkungen des Aluminiums auf den Menschen untersuchen werde.

Anschließend werde ich noch die Auswirkungen des Aluminiums auf die Ökologie darlegen, um daraufhin durch einen praktischen Versuch nachzuweisen, ob das Leichtmetall einen sichtbaren Einfluss auf die Pflanze und ihr Wachstum hat.

Micropaleontology: Principles and Applications by Pratul Kumar Saraswati,M.S. Srinivasan

By Pratul Kumar Saraswati,M.S. Srinivasan

This booklet may help readers research the elemental abilities had to learn microfossils particularly these with no formal heritage in paleontology. It info key rules, explains the way to determine diverse teams of microfossils, and gives perception into their capability functions in fixing geologic difficulties. uncomplicated ideas are addressed with examples that discover the strengths and boundaries of microfossils and their geological documents. This evaluation offers an realizing of taphonomy and caliber of the fossil files, biomineralization and biogeochemistry, taxonomy, strategies of species, and easy techniques of ecology. Readers know about the most important teams of microfossils, together with their morphology, ecology, and geologic history.

Coverage comprises: foraminifera, ostracoda, coccolithophores, pteropods, radiolaria, diatoms, silicoflagellates, conodonts, dinoflagellates, acritarch, and spores and pollens. during this insurance, marine microfossils, and especially foraminifera, are mentioned in additional element in comparison with the opposite teams as they proceed to play an enormous function in so much medical investigations. one of the a variety of tracers of earth background, microfossils give you the so much different different types of info to earth scientists. This richly illustrated quantity can help scholars and execs comprehend microfossils, and supply perception on easy methods to paintings with them to higher comprehend evolution of lifestyles, and age and the paleoenvironment of sedimentary strata.

Homology: The Hierarchial Basis of Comparative Biology by Brian K. Hall

By Brian K. Hall

Homology, the similarity among organisms that's because of universal ancestry, is the significant notion of all comparative biology. despite the fact that, the appliance of this idea varies reckoning on the knowledge being tested. This quantity represents a cutting-edge therapy of the various functions of this unifying notion. Chapters care for homology on all degrees, from molecules to behaviour, and are authored via best individuals to systematics, common heritage, and evolutionary, developmental, and comparative biology.

  • Commemoration of the a hundred and fiftieth anniverary of Sir Richard Owen's seminal paper distinguishing homology from analogy
  • Contributors who're well known leaders in compative biology
  • Coverage that's either complete and interdisciplinary

Lake Ecology in Kashmir, India: Impact of Environmental by Mubashir Jeelani

By Mubashir Jeelani

This publication highlights the anthropogenic pressures at the clean water our bodies and particularly, the Dal and Anchar Lake. because of weather swap and worldwide warming there's a probability that the glaciers which feed those water our bodies might be lost.
The lakes mentioned during this quantity can turn out an important resource of knowledge on water and biodiversity in addition to the environmental good points. The certain exam of phytoplankton and zooplankton during this quantity will end up a key issue for destiny reports within the box of biology and ecology. An in-depth research at the physical-chemical houses of the lakes' water is usually presented.

Desertifikation. Erscheinungsformen, Entwicklung und by Christiane Weiner

By Christiane Weiner

Studienarbeit aus dem Jahr 2004 im Fachbereich Biologie - Ökologie, notice: sehr intestine, Universität Bremen (Ökologie), Veranstaltung: Grundwissen Umweltschutz, 14 Quellen im Literaturverzeichnis, Sprache: Deutsch, summary: Der Begriff „Desertifikation“ kommt aus dem Lateinischen „desertus facere“, used to be verwüsten bedeutet. Unter Desertifikation versteht guy die anthropogen verursachte Ausbreitung wüstenähnlicher Verhältnisse in Gebiete hinein, in denen sie zonal-klimatisch eigentlich nicht existieren. Nach der UNCOD 1977 (United countries convention on Desertification) wird Desertifikation folgendermaßen definiert: “Desertification is the impoverishment of arid, semi-arid and a few subhumid ecosystems through the impression of man`s task [..] Desertification is the results of land abuse.” (UN 1977)
Nicht durch den Menschen verursachte Ausbreitung wüstenhafter ökologischer Verhältnisse, die vor allem am Zustand des Bodens und der crops sichtbar werden, bezeichnet guy als Desertion.
Der heute weltweit verwendete Terminus „Desertifikation“ wurde erst durch die oben genannte UN-Konferenz allgemein bekannt. Diese wurde 1977 als Folge einer verheerenden Dürrekatastrophe in der Sahelzone nach Nairobi einberufen. Die von 1969-1974 andauernde Dürre im südlichen Randbereich der Sahara und die in der Folge verstärkt auftretende Ausbreitung wüstenhafter Bedingungen in dieser ursprünglichen Dornsavannenregion warfare allerdings nur ein point, das die Initiierung bzw. Beschleunigung des Desertifikations-prozesses steuerte. Andere, und nicht weniger wichtige Auslöser und Steuerfaktoren dieses Geschehens waren Nutzungsfehler der in dieser zone wirtschaftenden Menschen, insbesondere auf dem agrarischen Sektor.

Estuarine Nutrient Cycling: The Influence of Primary by Søren Laurentius Nielsen,Gary T. Banta,Morten Foldager

By Søren Laurentius Nielsen,Gary T. Banta,Morten Foldager Pedersen

It is a well known proven fact that eutrophication of coastal waters explanations major adjustments within the species composition of the first manufacturers. frequently a shift from an environment ruled via sea grasses or huge brown algae to an atmosphere ruled by way of fast-growing eco-friendly algae or phytoplankton is saw. whereas this shift has been documented in a couple of learn papers and books, the implications of this shift are much less popular. This e-book makes a speciality of the results of such adjustments for nutrient biking.


The target is to enquire how forms of basic manufacturers impression nutrient biking in coastal marine waters, and the way nutrient biking alterations qualitatively and quantitatively because of the adjustments within the fundamental manufacturer group because of eutrophication. many of the chapters handle particular ecological approaches corresponding to grazing, decomposition, burial and export of biomass from the environment. The booklet is meant for researchers and pros operating within the box of coastal marine ecology and estuarine ecology and for complicated scholars during this field.

Lessons from Amazonia: The Ecology and Conservation of a by Richard Bierregaard Jr.,Mr. Claude Gascon,Thomas E.

By Richard Bierregaard Jr.,Mr. Claude Gascon,Thomas E. Lovejoy,Ms. Rita Mesquita

Deforestation is going on at an alarming cost in lots of components of the area, inflicting destruction of normal habitat and fragmentation of what continues to be. Nowhere is that this challenge extra urgent than within the Amazon rainforest, that's speedily vanishing within the face of large strain from people to take advantage of it.
