Abstract:
<p> Life-history research explores how environmental variation and physiological constraints shift the energy allocation decisions to competing functions of the body among individuals and populations. Variation in the energy available across the environmental landscape is of particular interest as it dictates the amount energy available for organisms to acquire and allocate to their life-history. Additionally, individuals vary in their ability to capture and assimilate energy from the environment. This dissertation seeks to understand how environmental variation in energy availability and phy

Full text
Abstract:
A key aspect underpinning life-history theory is the existence of trade-offs. Trade-offs occur because resources are limited, meaning that individuals cannot invest in all traits simultaneously, leading to costs for traits such as growth and reproduction. Such costs may be the reason for the sub-maximal growth rates that are often observed in nature, though the fitness consequences of these costs would depend on the effects on lifetime reproductive success. Recently, much attention has been given to the physiological mechanism that might underlie these life-history trade-offs, with oxidative s

Abstract:
Animals trade-off limited resources among competing demands. Trade-offs are difficult to quantify because it is challenging to measure investment into disparate physiological systems using a common scale. Additionally, biologists desire methods to more precisely measure energy status in wild animals. I used stable isotopes to help solve both of these problems. I examined natural spatial and temporal variation in stable isotope signatures of wild lizards and found significant variation. In the lab, I was able to demonstrate the utility of nitrogen stable isotope ratios of uric acid pellets for

It is estimated that there are approximately 1030 ocean virioplankton (Suttle 2007; Parsons et al. 2012).

Recent advances in genomics has revealed such viruses encode a multitude of genes, often acquired horizontally, that act to redirect metabolism for their own gains (Mann et al. 2003; Lindell et al. 2004a; Millard et al. 2009; Sullivan et al. 2010; Hurwitz et al. 2013; Enav et al. 2014).

Terebrasabella heterouncinata is a small K-selected sabellid polychaete.

Despite its low fecundity, this worm has become problematic on abalone farms in South Africa. The present study was conducted to gain an understanding of the life history patterns of T. helerouncinata to determine how they contributed to the success of these worms under altered conditions.

(some col.)<br>In seasonal environments, the ability to take advantage of the favorable seasons and avoid or mitigate the effects of the unfavorable ones is essential for organismal fitness. Many polar and temperate organisms use photoperiod (length of day) to time seasonal life history events because photoperiod's regular annual cycle makes it a very reliable indicator of seasonality. This reliability allows organisms to anticipate and properly prepare for seasonal change. Although photoperiodism is widespread in polar and temperate vertebrates, little is known relative to

Este trabalho acompanha o desenvolvimento da filosofia de Condillac do Ensaio sobre a Origem dos Conhecimentos Humanos até o Tratado dos Animais, obra em que o autor se aplica à definição daquilo que é próprio do humano e que se pode considerar a mais completa descrição de seu sistema de pensamento. A partir da reconstrução da noção de Metafísica do abade, encontramos uma interessante articulação entre as discussões científicas da época e a tentativa de estabelecer um novo fundamento para todo discurso possível, apoiado nas noções de natureza, humano, língua e moral.

Abstract:
MacroH2A1.1 is one of the least understood histone variants and structural components of chromatin. Generated by alternative splicing, macroH2A1.1 differs from the other macroH2A1 isoform in its capacity to bind NAD+-derived metabolites in vitro. This observation intrigued us to speculate that macroH2A1.1 could link metabolic and epigenetic regulation. To test the importance of this observation, we turned to skeletal muscle as this tissue is expressing the highest levels of the metabolite-binding isoforms. We demonstrate a switch in macroH2A1 splicing from the metabolite non-binding isof

Ihre relativ einfache Kultivierbarkeit machte sie außerdem zu einen weit verbreiteten Modellorganismus limnologischer Grundlagenforschung.

Abstract:
Building on recent scholarship in the history of art which has started to reappraise the meaning of grotesque and scatological motifs, this thesis examines how digestion was conceived of as a model of creation, and how this was translated visually. Renaissance creativity was increasingly modelled on a series of natural processes like digestion, following a trend in favour of Aristotelian psychology. However, it has been largely overlooked in comparison to the bleeding, the pneumatic, and especially the procreative natural models, which have been extensively studied. The central argument of thi
