Download A Cybernetic View of Biological Growth: The Maia Hypothesis by Tony Stebbing PDF

By Tony Stebbing

Maia is the tale of an concept, and its improvement right into a operating speculation, that offers a cybernetic interpretation of the way progress is managed. development on the lowest point is managed by means of regulating the speed of development. entry to the output of regulate mechanisms is supplied via perturbing the transforming into organism, after which filtering out the implications to development fee. The output of the expansion keep watch over mechanism is then available for interpretation and modeling. Perturbation experiments were used to supply interpretations of hormesis, the neutralization of inhibitory load and bought tolerance to poisonous inhibition, and catch-up development. The account starts off with an creation to cybernetics overlaying the legislation of development and inhabitants raise in animals and guy and describes this new method of entry the regulate of development strategies. This ebook is appropriate for postgraduate scholars of organic cybernetics and researchers of organic progress, endocrinology, inhabitants ecology and toxicology.

Light and plant development

Dwelling organisms are topic to fluctuating environmental stipulations. while so much animals may be able to stream clear of destructive stipulations, vegetation are sessile and so needs to focus on no matter what comes their method. Of the entire environmental cues that problem the constructing plant, mild can most likely be thought of to be an important.

Plasticity, Robustness, Development and Evolution

How will we comprehend and clarify the obvious dichotomy among plasticity and robustness within the context of improvement? do we determine those complicated tactics with out resorting to 'either/or' ideas? Written by means of leaders within the box, this can be the 1st ebook to completely get to the bottom of the complexity of the topic, explaining that the epigenetic techniques producing plasticity and robustness are in reality deeply intertwined.

Atlas of Zebrafish Development

Zebrafish are broadly thought of an outstanding model system for vertebrate improvement. The embryo is obvious, thereby permitting visualization and use of labelling and transgenic techniques. additionally, a result of ease of inducing new mutations in zebrafish and similarity with the human genome, this organism can be utilized successfully for affliction reviews.

Environmental sex differentiation in fish

Fish represent a tremendous typical renewable source and any aid of their skill to propagate because of human interference could have major socioeconomic results. The detrimental influence of human task on intercourse differentiation and reproductive output in fish is so different that it's been tough to surround it in one booklet.

4), it can be seen how the relative rate declines and generation time increases in approximate order of size. The graph of relative growth rate against generation time produces a remarkable result: the fastest-growing animals, with the shortest generation time, tend to be smaller and simpler organisms, while the slower-growing animals with longer generation times tend to be larger and more complex organisms. 4. 5). progress from small to large, from simple to complex, and from shortlived to long-lived.

These precious samples were among the first to be brought up from the ocean deeps, and provided an early glimpse of life in the abyss. The samples were passed to Huxley for microscopic analysis. He was soon able to show that for 1,700 miles across the North Atlantic, the abyssal plain at 3,000 metres deep was covered by fine calcareous sediments packed with the shells of globigerinae, such that the mud – known as ‘globigerine ooze’ – was found to cover nearly 50% of the deep-sea floor. It consisted almost exclusively of calcium carbonate derived from the remains of planktonic life forms that had settled after the death of the plankton living in the surface waters far above.

The Plague of Frogs that followed may have been caused by rotting fish driving the amphibians from the water. The Plague of Flies is thought to have been Stomoxys calcitrans, which multiplied rapidly on the accumulated fish and frog corpses. The Plague of Gnats were likely to have bred in the flooded fields in late autumn, while the Plague of Livestock Death was a disease of domesticated animals, possibly due to the flies of the earlier plague acting as carriers of the Anthrax bacillus. The Plague of Boils that followed may have been due to skin anthrax in both humans and animals.
