Abstract (sommario):

As medical technology has advanced, so too have our attitudes towards the level of control we can expect to hold over our procreative capacities. This creates a multi-dimensional problem for the law in terms of access to services which prevent conception, access to services which terminate a pregnancy and recompensing those whose choices to avoid procreating are frustrated. These developments go to the heart of our perception of autonomy. In order to evaluate these three issues in relation to reproductive autonomy, I set out to investigate how the Gewirthian theory of ethical rationalism can b

Abstract (sommario):

Surrogacy is an arrangement whereby a woman conceives in order to give birth to child or children for another individual or couple to raise. This thesis explores how commercial gestational surrogacy is culturally framed and socially organised in Russia and investigates the roles of the key actors. In particular it explores the experiences of surrogacy workers, including those who migrate or commute long distances within and to Russia for surrogacy work and the significance of their origin, citizenship, ethnicity and religion in shaping their experience. Ethnographic fieldwork was carried out i

Abstract (sommario):

This body of work examines law’s response to non-genetic families. I have always centred the experience of family formation and family life such that I have traversed and linked distinct legal sites and doctrines, examining access to family formation avenues, models for legal recognition of families once formed and, latterly, legal responses to information sharing and broader kinship practices among genetically related individuals in childhood and later life. In doing so I have made a major contribution to a body of scholarship centring ‘lived lives’ in the exploration of family, relationship

Abstract (sommario):

The reproductive justice movement gives a voice and representation to women of color whose experience of reproductive control is impacted by intersecting layers of oppression. This thesis uses an intersectional approach to develop the concept of racial reproductive control logics, which describes the relationship between racial logics and racial patterns of reproductive control. The study uses qualitative interviews and content analysis of organizational material to explore how the reproductive justice movement is influenced by racial reproductive control logics.

Abstract (sommario):

The motivation behind the research paper, “Between reproductive rights and access to reproductive healthcare services: Narratives of reproductive rights activists in South Africa” stems from the notion that civil society groups have often played a critical role in addressing social justice issues concerning women’s rights. Since 1996 after implementation of the Choice on Termination of Pregnancy (CTOP) Act, South Africa has frequently been praised for its progressive abortion laws that formally recognises women’s need for reproductive autonomy and equality. However, ineffective implementation

Abstract (sommario):

Cobia aquaculture began in Australia in 2007; however, expansion of commercial production has been limited, due in part to low and inconsistent supply of seed stock for ongrowing.

Abstract (sommario):

State regulation of assisted reproductive technology (ART) has been occurring since the inception of earlier technological advances such as artificial insemination to aid human reproduction. I provide a brief overview of the current regulation of ART in the U.S. and the literature on state regulation. Unlike previous studies of ART regulation which use content analysis or case studies of individual state laws I estimate ART regulation for the entire U.S. by using a series of random effects logistic regression models for the time period 1995-2006. To my knowledge this is the first quantitative

Abstract (sommario):

Viviparity has evolved multiple times within squamates. Eggshells are reduced in viviparous forms, which reduces calcium available to embryos during development. This study tested the hypothesis that reduced calcium impacts neonates of viviparous forms. Developmental series from oviparous and viviparous populations of Zootoca vivipara (reproductively bimodal) were cleared & stained to reveal bone development. Photographs (high magnification, calibrated to size) were used to obtain measurements of lengths of the body, humerus, femur, skull and lower jaw, and of ossified portions of limb bones.

El contexto reproductivo español ha sido descrito como de “infertilidad estructural” (Marre, 2009), a causa del descenso de la fecundidad desde mediados de los años 70, debido principalmente a las condiciones del mercado laboral (Marre, 2009), los discursos feministas que vinculaban la libertad de las mujeres con la no-maternidad (Marre, 2012 a Briggs et al., 2012) y a la falta de políticas públicas de apoyo a la maternidad (Comas d’Argemir et al., 2016).

I find that mean egg size decreases with increasing clutch size in <i>Daphnia, </i>and explore possible causes of this using a mathematical model. This pattern could be an adaptive response, if larger offspring have greater fitness advantages in food-limited environments. However, such

The proportion of resources which an organism devotes to reproduction has been assumed to be of great evolutionary and ecological significance.

An attempt was made to determine the 'best' method of measuring RA and then apply this to a range of species with differing ecological strategies.

In advanced eusocial hymenopteran societies workers have ovaries and can lay eggs, but are unable to mate. Workers are more related to their own offspring than to every other member of the colony. So worker reproduction contains both worker-worker and worker-queen conflict. The queen- worker conflict is discussed elsewhere, but if the queen mates with more than two males, worker policing should be selected to lower potential conflicts. However in the Cape honeybee it was predicted that worker policing is absent or less expressed than in other honeybee subspecies, because workers produce female

For example, fecund individuals may or may not be sexually active, may or may not be using contraception, which would in uence their degree of risk for pregnancy. In this context, fecundity

Organisms in temperate zones time reproduction to occur when conditions are optimal for raising offspring. However, individuals of many taxa vary in precise timing of breeding. The mechanisms underlying the existing variation are not well understood, particularly in females. I hypothesized that individual variation in daily (i.e., circadian) rhythms, which are highly conserved across taxa, are related to variation in reproductive timing. By measuring activity onset in two species of songbirds, we found that females beginning their day earlier also breed earlier. I further asked if sex-steroid

Although genomes are perhaps the single most important element of living systems, why they feature such striking variation and how this variation is maintained within and across natural populations remains unclear. One of the most common and important means by which genomic variation is generated is ploidy elevation. While polyploidy has been implicated in the remarkably successful radiations of angiosperms, teleost fish, and amphibians, the phenotypic consequences of changes in ploidy level are poorly understood, especially in animals.
