Tausche Sex gegen Nahrung: Eine Untersuchung über das gleichgeschlechtliche soziosexuelle Verhalten weiblicher Bonobos (Pan paniscus) bei der Nah
ISBN: 9783656251187 / Niemiecki / Miękka / 62 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Examensarbeit aus dem Jahr 2010 im Fachbereich Psychologie - Biologische Psychologie, Sprache: Deutsch, Abstract: Das Teilen von Nahrung ist kein seltenes Phanomen unter Primaten. Meist kann dieses Verhalten auf Basis der Verwandtschaftsselektion erklart werden. Betrachtet man jedoch das Teilen von Nahrung bei Bonobos, fallen zwei Besonderheiten auf. Erstens teilen am haufigsten die aufgrund der patrilinearen Gruppenstruktur nicht oder nur entfernt verwandten Weibchen die Nahrung miteinander (Kano, 1980), was die Frage aufkommen lasst, welche Faktoren dieses Verhalten zwischen...

Encyclopedia of Metagenomics
ISBN: 9781461446743 / Angielski / Twarda / 1528 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Metagenomics has taken off as one of the major cutting-edge fields of research. The field has broad implications for human health and disease, animal production, and environmental health. Metagenomics has opened up a wealth of data, tools, technologies and applications that allow us to access the majority of organisms that we still cannot access in pure culture (an estimated 99% of microbial life). Numerous research groups are developing tools, approaches and applications to deal with this new field, as larger data sets from environments including the human body, the oceans and soils are...

Hippodamia convergens
ISBN: 9783659001918 / Angielski / Miękka / 172 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This study aimed to investigate the population fluctuations of aphids and their associated predators in alfalfa, faba bean, cantaloupe and apricot trees at Ismailia Governorate, Egypt. Obviously, Hippodamia convergens Guerin-Meneville was the dominant predator associated with aphid infestations on all studied crops. In biological studies, data indicated that temperature had a significant influence on the development, feeding consumption, immature survival, adult longevity, ovipositional periods, and fecundity of Hippodamia convergens. Moreover, prey type affected development, feeding...

Host type and textures on the survival of Tribolium castaneum
ISBN: 9783659135514 / Angielski / Miękka / 104 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Worldwide losses in stored products, caused by insects, have been estimated to be between five and ten percent. Heavier losses occurring in the tropics may reach 30% and the net value of losses in storage in the United States has been placed at over $200 million annually. Such loss may reach up to 40%, in countries where modern storage technologies have not been introduced like Ethiopia. These and other factors mentioned in the introductory part of this book are evidences that indicate the relevance of both primary and secondary insect pests as pests of stored products. Therefore, there is a...

ISBN: 9783848484928 / Angielski / Miękka / 116 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Beta lactamases are the group of enzymes which are produced by some bacteria and they hydrolyze the β-lactam ring of the β-lactam antibiotics. Different strains of gram negative bacteria were isolated from these samples and identified as E. coli, Enterobacter and Klebsiella. Sensitivity of these bacterial strains was checked against different classes of antibiotics e. g. aminoglycosides, cephalosporins, carbapenems and trimethoprim-sulfamethoxazole by disc diffusion technique. These strains were analyzed for the production of beta lactamases which was then confirmed by double disc...

This experience was conducted to test and study the pig behavior and welfare in their competition for the facilities, analyzing as much as possible the drinking, feeding and rooting behaviors in two different pen sizes and animal densities. Under the EU regulations and having in mind that welfare is already an imperative issue, an overlook in this subject matter could help farmers in their future orientations. Nevertheless, behavior measurements are a difficult subject to analyze and reach definitive conclusions.
