Biology of shallow marine ichnology: a modern perspective

Modern Biology: A

In the past twenty years, one has heard much talk of a biological revolu.tion and ‘of its consequences for mankind--no’t only in medical and economic achievement but in the nature of man itself. Man may soon be able b influence his own heredity directly, rather than only by the indirect process of eugenics. Scientists and soience writers discuss suoh prospects with ;~n uneasy mixture of optimis...

The ‘mediotype’: a powerful tool for modern ichnology based on 3D models

Vertebrate tracks are subject to a wide range of morphological variation. A single trackmaker may be associated with a range of tracks reflecting individual pedal anatomy and behavioural kinematics mediated through substrate properties which may vary both in space and time. Accordingly, the same trackmaker can leave substantially different morphotypes something which must be considered in creat...

Bathymetry and body size in marine gastropods: a shallow water perspective

Spatial patterns of species body size across major environmental gradients are being quantified for terrestrial organisms, but similar efforts are largely lacking for marine invertebrates. Bathymetry represents a major environmental gradient in the oceans, and existing theoretical models predict that species body size should decrease with increasing depth, especially for deep-sea species. Previ...

The ‘mediotype’: a powerful tool for modern ichnology based on 3D models (#18800)

Origins of Modern Biology

The new book has three parts, consisting of bacterial physiology, im-munology, and virology. The aim is to provide a text for college and graduate students taking general microbiology or immunology. It reduces the bulk and expense of the parent volume by deleting chapters on antimicrobial defences of the host and pathogenic bacteria, fungi, and viruses. The main emphasis is on molecular genetic...
