Maria McCann paints a dark picture of masculinity and its effects in her novel As Meat Loves Salt (2001). The violent Jacob Cullen struggles with his masculinity as he faces the intricacies of religion, sexuality and politics in the midst of the English Civil War where he falls in love with fellow soldier Christopher Ferris. By using R.W. Connell and James Messerschmidt’s framework for the hierarchy of masculinities, I explore masculinities on local, regional and global levels and emphasized femininity in a close reading of McCann’s novel. My aim is not only to analyse the masculinities of the novel but also to use the framework to redefine toxic masculinity in order to make it a useable concept when analysing masculinities in literature. I redefine toxic masculinity because it lacks a clear definition anchored in an established framework used to study masculinity that does not see masculinity as inherently toxic. I believe that anchoring it to Connell and Messerschmidt’s framework will make it a useable concept. Due to the novel’s relationship to the Bible, I will use masculinity studies done on David and Jesus from the Bible to compare and reveal similarities with the masculinities in the novel, how they appear on the local, regional and global levels in the novel and its effects. I draw parallels between the love story in As Meat Loves Salt to the love story of David and Jonathan in the Bible by using queer readings of David and Jonathan in order to explore how masculinity affects the relationships and how the novel uses these two love stories as a study of toxic masculinity and how it relates it to hegemonic masculinity.

Central to animal studies is the question of words and how they are used in relation to wordless beings such as non-human animals. This issue is addressed by the writer D.H. Lawrence, and the focus of this thesis is the linguistic vulnerability of humans and non-humans in his novel Women in Love, a subject that will be explored with the help of the philosopher Jacques Derrida’s text The Animal That Therefore I Am. The argument is that Women in Love illustrates the human subjection to and constitution in language, which both enables human thinking and restricts the human ability to think without words. This linguistic vulnerability causes a similar vulnerability in non-human animals in two ways. First, humans tend to imagine others, including non-verbal animals, through words, a medium they exist outside of and therefore cannot be defined through. Second, humans are often unperceptive of non-linguistic means of expression and they therefore do not discern what non-human animals may be trying to communicate to them, which often enables humans to justify abuse against non-humans. In addition, the novel shows how this shared but unequal vulnerability can sometimes be dissolved through the likewise shared but equal physical vulnerability of all animals if a human is able to imagine the experiences of a non-human animal through their shared embodiment rather than through human language. Hence the essay shows the importance of recognizing the limitations of language and of being aware of how the symbolizing effect of words influences the human treatment of its others.

Propionate, a carbon substrate abundant in many prefermenters, has been shown in several previous studies to be a more favorable substrate than acetate for enhanced biological phosphorus removal (EBPR). The anaerobic metabolism of propionate by polyphosphate accumulating organisms (PAOs) is studied in this paper. A metabolic model is proposed to characterize the anaerobic biochemical transformations of propionate uptake by PAOs. The model is demonstrated to predict very well the experimental data from a PAO culture enriched in a laboratory-scale reactor with propionate as the sole carbon source. Quantitative fluorescence in-situ hybridization (FISH) analysis shows that Candidatus Accumulibacter phosphatis, the only identified PAO to date, constitute 63% of the bacterial population in this culture. Unlike the anaerobic metabolism of acetate by PAOs, which induces mainly poly-beta-hydroxybutyrate (PHB) production, the major fractions of poly-beta-hydroxyalkanoate (PHA) produced with propionate as the carbon source are poly-beta-hydroxyvalerate (PHV) and poly-beta-hydroxy-2-methylvalerate (PH2MV). PHA formation correlates very well with a selective (or nonrandom) condensation of acetyl-CoA and propionyl-CoA molecules. The maximum specific propionate uptake rate by PAOs found in this study is 0.18 C-mol/C-mol-biomass h, which is very similar to the maximum specific acetate uptake rate reported in literature. The energy required for transporting 1 carbon-mole of propionate across the PAO cell membrane is also determined to be similar to the transportation of 1 carbon-mole of acetate. Furthermore, the experimental results suggest that PAOs possess a similar preference toward acetate and propionate uptake on a carbon-mole basis. (c) 2005 Wiley Periodicals, Inc.

Ecological genetic studies have demonstrated that spatial patterns of mating dispersal, the dispersal of gametes through mating behaviour, can facilitate inbreeding avoidance and strongly influence the structure of populations, particularly in highly philopatric species. Elements of breeding group dynamics, such as strong structuring and sex-biased dispersal among groups, can also minimize inbreeding and positively influence levels of genetic diversity within populations. Rock-wallabies are highly philopatric mid-sized mammals whose strong dependence on rocky terrain has resulted in series of discreet, small colonies in the landscape. Populations show no signs of inbreeding and maintain high levels of genetic diversity despite strong patterns of limited gene flow within and among colonies. We used this species to investigate the importance of mating dispersal and breeding group structure to inbreeding avoidance within a 'small' population. We examined the spatial patterns of mating dispersal, the extent of kinship within breeding groups, and the degree of relatedness among brush-tailed rock-wallaby breeding pairs within a colony in southeast Queensland. Parentage data revealed remarkably restricted mating dispersal and strong breeding group structuring for a mid-sized mammal. Breeding groups showed significant levels of female kinship with evidence of male dispersal among groups. We found no evidence for inbreeding avoidance through mate choice; however, anecdotal data suggest the importance of life history traits to inbreeding avoidance between first-degree relatives. We suggest that the restricted pattern of mating dispersal and strong breeding group structuring facilitates inbreeding avoidance within colonies. These results provide insight into the population structure and maintenance of genetic diversity within colonies of the threatened brush-tailed rock-wallaby.

Many endangered species worldwide are found in remnant populations, often within fragmented landscapes. However, when possible, an understanding of the natural extent of population structure and dispersal behaviour of threatened species would assist in their conservation and management. The brush-tailed rock-wallaby (Petrogale penicillata), a once abundant and widespread rock-wallaby species across southeastern Australia, has become nearly extinct across much of the southern part of its range. However, the northern part of the species' range still sustains many small colonies closely distributed across suitable habitat, providing a rare opportunity to investigate the natural population dynamics of a listed threatened species. We used 12 microsatellite markers to investigate genetic diversity, population structure and gene flow among brush-tailed rock-wallaby colonies within and among two valley regions with continuous habitat in southeast Queensland. We documented high and signifcant levels of population genetic structure between rock-wallaby colonies embedded in continuous escarpment habitat and forest. We found a strong and significant pattern of isolation-by-distance among colonies indicating restricted gene flow over a small geographic scale (< 10 km) and conclude that gene flow is more likely limited by intrinsic factors rather than environmental factors. In addition, we provide evidence that genetic diversity was significantly lower in colonies located in a more isolated valley region compared to colonies located in a valley region surrounded by continuous habitat. These findings shed light on the processes that have resulted in the endangered status of rock-wallaby species in Australia and they have strong implications for the conservation and management of both the remaining 'connected' brush-tailed rock-wallaby colonies in the northern parts of the species' range and the remnant endangered populations in the south.
