Abstract

This book contains the proceedings of the International Symposium on the Mechanisms of Sexual Reproduction in Animals and Plants, where many plant and animal reproductive biologists gathered to discuss their recent progress in investigating the shared mechanisms and factors involved in sexual reproduction. This now is the first book that reviews recent progress in almost all fields of plant and animal fertilization. It was recently reported that the self-sterile mechanism of a hermaphroditic marine invertebrate (ascidian) is very similar to the self-incompatibility system in flowering plants. It was also found that a male factor expressed in the sperm cells of flowering plants is involved in gamete fusion not only of plants but also of animals and parasites. These discoveries have led to the consideration that the core mechanisms or factors involved in sexual reproduction may be shared by animals, plants and unicellular organisms. This valuable book is highly useful for reproductive biologists as well as for biological scientists outside this field in understanding the current progress of reproductive biology.

Abstract

The Great Lagoon is a central part of the Szczecin Lagoon, a major component in the Odra River estuary system. It is also an important European natural heritage site and one of the largest resting places for migratory birds in the Baltic Sea area. The first part of Wolnomiejski's and Witek’s book gives a thorough overview of the most up-to-date knowledge of this region, including the assessment of its biological production. Based on these findings authors develop a food web model of the Polish part of the Szczecin Lagoon, identifying a total of 45 trophic-functional components. The model describes a variety of features ranging from the magnitude of consumption, to the amount of unassimilated food and export of individual system components, and serves as an invaluable source, helping researchers to estimate various ecological indicators of The Great Lagoon’s ecosystem.

Abstract

In this chapter, I develop a set of concepts and methodological principles that researchers might draw on as they try to elucidate the processes by which the engagement of humans with their social worlds, material environments, and historical cultures results in the formation of a self in subject, corporeal, and biological dimensions. I forge a conceptual language and rules for analysis that may enable scholars to negotiate converging accounts of how the social norms, lived environments, and power relations through which people develop a sense of self are bound up with processes through which biological organisms compose and recompose themselves over time.

Abstract

The rules by which anatomical size and shape are generated have intrigued scientists&#xD;for centuries. In 1638, Galileo suggested a mathematical relationship between proportional&#xD;changes in the shape of bones as animals increase in size, which he argued&#xD;was a functional necessity for weight bearing (1914). The formalism of Galileo,&#xD;whereby, physical forces and mathematical laws became integrated with studies&#xD;of size and shape in biology, was most conspicuously encapsulated over a hundred&#xD;years ago in the 1917 monumental tome by D’Arcy Thompson entitled, On Growth&#xD;and Form (Thompson 1917). In a breathtakingly comprehensive manner, Thompson&#xD;synthesized the observations of numerous predecessors and contemporaries, and&#xD;through countless examples built a theoretical and experimental framework for&#xD;describing changes in morphology that persists to this day (Stern and Emlen 1999;&#xD;Arthur 2006).

Abstract

Most infections and traumatic injuries are cleared or repaired relatively rapidly and metabolic homoeostasis is soon restored. However, there is a broad range of inflammatory&#xD;diseases which involve chronic activation of the immune system and, as a result, chronic&#xD;persistent inflammation. We have been studying the metabolic consequences of chronic&#xD;inflammatory diseases with the aim of identifying metabolic fingerprints which may&#xD;provide clues about why the localised tissue disease persists.

Abstract

Ageing is a complex process that affects all living organisms. Senescence is not only conceivable in multicellular organisms, but also in unicellulars. Unlike certain diseases that&#xD;have specific morbidity rates, ageing is a physiological process that affects all individuals&#xD;that live long enough (unaffected by i.e. predation or famine) to experience senescence.

Abstract

"Contemporary biology is called to accommodate the idea that while DNA is involved in the formation of an individual, the other constituents of the organism or of its environment are also determining factors. Nothing is ""programmed"" as such, and the challenge is to understand how the whole is assembled and structured. Five researchers from different scientific horizons here provide new and complementary insights into the singularity and auto-organization of living systems.&#xD;The book includes a discussion glossary covering around thirty key notions, from adaptation to variability."&#xD;

Abstract

Ecklonia radiata is one of the most widespread kelps globally, dominating temperate reefs throughout&#xD;much of Australasia and southeastern Africa. Throughout much of its range, it is the only laminarian&#xD;kelp and hence plays a key role in facilitating biodiversity and driving food webs, and it underpins&#xD;immense ecological and socioeconomic values. This review synthesises the growing literature on&#xD;E. radiata from its phylogeny and distribution through to its biology, ecology and recent changes. It provides an assessment of the state of knowledge and identifies gaps in our understanding of this&#xD;important species. Despite being tolerant of a wide range of abiotic conditions, recent environmental&#xD;change has caused direct and indirect loss of E. radiata forests, with extensive areas transitioning to&#xD;turf and urchin barrens. Ongoing climate change may require application of multifaceted and novel&#xD;strategies to increase its resistance and resilience to future conditions. By integrating variation across&#xD;space, time and environmental change, this review provides a description of the current status and&#xD;possible future trajectories of E. radiata forests.

Abstract

Since the discovery of the Warburg effect in the 1920s cancer has been tightly associated with the genetic and metabolic state of the cell. One of the hallmarks of cancer is the alteration of the cellular metabolism in order to promote proliferation and undermine cellular defense mechanisms such as apoptosis or detection by the immune system. However, the strategies by which this is achieved in different cancers and sometimes even in different patients of the same cancer is very heterogeneous, which hinders the design of general treatment options.Recently, there has been an ongoing effort to study this phenomenon on a genomic scale in order to understand the causality underlying the disease. Hence, current “omics” technologies have contributed to identify and monitor different biological pieces at different biological levels, such as genes, proteins or metabolites. These technological capacities have provided us with vast amounts of clinical data where a single patient may often give rise to various tissue samples, each of them being characterized in detail by genomescale data on the sequence, expression, proteome and metabolome level. Data with such detail poses the imminent problem of extracting meaningful interpretations and translating them into specific treatment options. To this purpose, Systems Biology provides a set of promising computational tools in order to decipher the mechanisms driving a healthy cell’s metabolism into a cancerous one. However, this enterprise requires bridging the gap between large data resources, mathematical analysis and modeling specifically designed to work with the available data. This is by no means trivial and requires high levels of communication and adaptation between the experimental and theoretical side of research.
