Abstract:

<p>Brown seaweeds lack lignin and have a low cellulose content. Thus, seaweeds should be an easier material for biological degradation than land plants. However, seaweeds have a complex composition, and complete degradation of the material necessitates the presence of microorganisms with a broad substrate range. During anaerobic degradation of organic material, energy carriers such as methane and ethanol may be produced. This is a study of two particular species of brown seaweeds; <i>Laminaria hyperborea</i> and <i>Ascophyllum nodosum</i>, which are the most abundant Norwegian species and also

Abstract:

Obesity is associated with insulin resistance, dyslipidemia, and cardiovascular disease. The current obesity epidemic is the result of surplus energy consumption. Excess energy is stored in expanding adipose tissue. Adipose tissue growth entails the enlargement of existing adipocytes, the formation of new fat cells from preexisting progenitors, and the coordinated development of supporting vasculature. Identifying adipocyte progenitors and the mechanism of adipose tissue expansion is crucial for the development of new strategies to combat obesity and its complications. Though important progres

The aim of this thesis is to use a cross-match between WISE, 2MASS and SDSS to identify a large sample of M dwarfs. Through the careful characterisation and quality control of these M dwarfs I aim to identify rare systems (i.e. unresolved UCD companions, young M dwarfs, late M dwarfs and M dwarfs with common proper motion companions). Locating ultracool companions to M dwarfs is important for constraining low-mass formation models, the measurement of substellar dynamical masses and radii, and for testing ultracool evolutionary models. This is done by using an optimised method for identifying M

The aim of this study was to investigate the molecular mechanisms of olfaction in the light brown apple moth, Epiphyas postvittana.

Abstract:

North American black bears and brown bears can be difficult to distinguish in the fossil record due to similar dental and skeletal morphologies. Challenges identifying ursid material from Oregon Caves National Monument (ORCA) called for an accurate tool to distinguish the species. This study utilized a large database of lower tooth lengths and ratios in an attempt to differentiate black and brown bears in North America. Further, this project examined how these linear measurements differ geographically. Analysis of variance (ANOVA) found significant differences between black and brown bears fro

Abstract:

This thesis demonstrates that many frog species, when stressed or challenged, produce odours that are associated with the skin gland secretions, and that the source of these odours can vary. The role of many of these odorous compounds is still unknown. However, it would appear that some odorous compounds have a defensive function and are important components of the secretions.<br>Thesis (Ph.D.) - University of Adelaide, Dept. of Environmental Biology and Dept. of Soil and Water, 2002

Abstract:

Acoustic communication in anurans plays a critical role in species recognition, defending territories and resources, and finding a mate. Anurans use a number of different call note types to communicate, from which the most notable are advertisement- and aggression calls. Optimum weather conditions are a precursor to the commencement of the breeding season for all frog species and their calling behaviour is therefore readily influenced by atmospheric conditions. Male frogs within a chorus also tend to call from territories within a specific range of distances from one another. The objectives of

碩士<br>國立臺北教育大學<br>自然科學教育學系碩士班<br>98<br>To understand the reproductive ecology and population abundance Rana longicrus among allopatric populations, I conducted my study at Pei-pu area. The study was started from November 2008 to November 2009 and conducted with the mark-recapture method. In this period, we had been caught 152 individuals (303 times) and the sex ratio was 1:2.38. The highest number of individual we had caught were75 (80 times) in December 2008. The recapture rate was 44.1% for the whole year and the ratio of female was 44.4% which was close to that of male (43.9%). In terms of

Abstract:

Current literature suggests that little, if any, research has been conducted in South Africa to determine the impact of alien invasive trout on indigenous amphibian biodiversity. The primary aim of the research project was to establish whether waterfalls are seasonally important in protecting the indigenous Natal Cascade Frog Hadromophryne natalensis tadpole populations from predation by alien rainbow trout Oncorhynchus mykiss and brown trout Salmo trutta at two sampling areas located at Injesuthi and Monk‟s Cowl Nature Reserve within the uKhahlamba Drakensberg Park World Heritage Site (UDPWHS
