Central Processing of Plant Odor Mixtures and Single Odorants in the Moth Heliothis virescens
(Master thesis, 2012)SamandragInsekt nyttar luktesansen til mange formål som er avgjerande for overlevnad og reproduktiv suksess. Ein veksande kunnskapsbase tyder på at miksturar av nokre få biologisk relevante plantevolatiler kan vekke ... -
Does human activities affect stress level in Serengeti elephants (Loxodonta africana)?
(Master thesis, 2011)African elephants play a vital role in the Serengeti ecosystem, with the opportunity to alter the entire ecosystem by their sheer number. Management of these animals with the ambition of improving their welfare is therefore ... -
Effect of experimentally increased adult foraging effort on the offspring in black legged kittiwakes (Rissa tridactyla)
(Master thesis, 2011)The Black legged Kittiwake (Rissa tridactyla) is one of the more extensively studied seagull species, and much of their nesting behaviour and physiology concerning the breeding period has already been examined to a high ... -
Effects of Crude Oil Water Accommodated Fractions (WAF) on the Escape Behaviour in Calanus finmarchicus Gunnerus (Copepoda)
(Master thesis, 2012)SammendragDen dominerende planktonorganismen i Atlanterhavet og Barentshavet er den calanoide kopepoden Calanus finmarchicus. Den er en nøkkelart i den marine næringskjeden, og har evnen til å lagre store mengder fett, som ... -
Effects of different live feed on larval growth and development in ballan wrasse (Labrus bergylta Ascanius, 1767): - A metabolomics study
(Master thesis, 2012)The use of ballan wrasse (Labrus bergylta) for the treatment of salmon lice (Lepeophtheirus samonis) in salmon farming is rapidly growing due to resistance to chemical treatments. The demand for high quality and large ... -
Fysisk prestasjon hos kvinnelige langrennsløpere i kulde og varme.: Termoregulatoriske og metabolske responser
(Master thesis, 2011)Bakgrunn: Langrennsutøvere blir utsatt for veldig varierende termisk stress. Termisk stress er vist å ha negativ effekt på prestasjonen til mannlige utholdenhetsutøvere. Prestasjon under fysisk aktivitet i kulde er mindre ... -
GABA Immunostaining of the Olfactory Pathway in the Heliothine Moth Brain
(Master thesis, 2012)γ-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in all known nervous systems, and it is widely distributed in the olfactory circuit as well as other parts of the invertebrate brain. In order to further ... -
Morphological Characterization of Descending Neurons and Determination of Output areas in the Brain of the Moth Heliothis virescens
(Master thesis, 2012)Knowledge on how an insect s behavior changes in response to chemical substances in the environment can ultimately contribute to the development of biologically harmless pest controls. One of the links between sensory ... -
Oksygenforbruk, stressrespons og stress under Aqui-S sedasjon hos bergnebb (Ctenolabrus rupestris) i transportrelaterte forsøk
(Master thesis, 2011)Dagens problem med lakselus på atlantisk laks (Salmo salar) er betydelig, og bakgrunn for store økonomiske tap. Fiskeridirektoratet anslår at 80 % av tap i matproduksjon av atlantisk laks er forårsaket av lakselus. ... -
Physiological Characterization of Protocerebral Neurons in the Olfactory Network of the Moth, Heliothis virescens
(Master thesis, 2011)In the sensory systems of insects, the primary olfactory centre in the antennal lobe has been one of the major areas of interest for the last two decades. Considerable progress has been made in understanding this earlier ... -
Plasma melatonin profiles in Common carp (Cyprinus carpio) exposed to indoor photoperiods
(Master thesis, 2011)An intervention against extreme poverty and hunger was introduced in year 2000, when all members of the United Nations agreed on the Millennium Development Goals (MDG). Today, 1.4 billion people live in poverty and hunger, ... -
Plasma melatonin profiles in copper mahseer (Neolissochilus hexagonolepis) kept under natural and manipulated photoperiods
(Master thesis, 2011)Abstract In many countries around the world, health problems related to food access are an increasing threat, and many people today still don t have access to sufficient protein and energy in their diet. In poor countries ... -
Plasma melatonin profiles in mrigal carp (Cirrhinus mrigala) kept under natural and manipulated photoperiods
(Master thesis, 2012)One major challenge in Asian aquaculture is the limited availability of carp fries. In order to establish out of season supply of fries, knowledge about the pineal melatonin clock and calendar function, and its influence ... -
Plasma melatonin profiles in silver carp (Hypophthalmichthys molitrix) during natural and manipulated photoperiods
(Master thesis, 2012)Photoperiodic manipulation of reproductive events in fish is suggested to secure all-year supply of fish fry in the Nepalese aquaculture. This could significantly improve food security and decrease poverty in Nepal. In ... -
Processing of Gustatory Information by Protocerebral Neurons in the Moth Heliothis virescens
(Master thesis, 2012)Insects are guided to potential host plants by visual and olfactory signals. Upon arrival they encounter various taste stimuli, ultimately deciding whether the plant is a proper food or oviposition source. The detection ...
