The Quarterly Review of Biology, 1960
Melanocytes may be regarded as unicellular, pigment-secreting glands, largely though not entirely confined to the epidermis, of which they are a constant though often un-recognized cellular component. Their numerical incidence, and their branching form, with numerous dichotomizing processes, are such as to form a reticular system within the epidermis ...

“Intelligent activity may reasonably be regarded as the key note of mammalian progress” (Romer 1962). This progress became possible with the acquisition of a neocortex, with its great analytic, associative and synthetic potential. Other mammalian characteristics, such as improvements in the circulation and in temperature regulation and, in most mammals,

Genetica, 1959
Eighteen new cases of colour mosaics are described. Previous reports of mosaics are collocated and briefly discussed. Various mechanisms are described which may engender three types of mosaicism. These are the (1) somatic, (2) the soma-gonadic and (3) the gonadic.

The Bulletin of Mathematical Biophysics, 1948
By considering the general energy balance between the energy of muscular contraction in the extremities, kinetic energy imparted to the animal and the energy lost in the lifting of the center of gravity and in the possible muscular viscosity, an expression is derived for the speed of an animal in terms of the constant which determine its shape and ...

Philosophical Psychology, 2006
Many traditional attempts to show that nonhuman animals are deserving of moral consideration have taken the form of an argument by analogy. However, arguments of this kind have had notable weaknesses and, in particular, have not been able to convince two kinds of skeptics.

Pharmacology & Therapeutics, 1992
It is not widely appreciated that mammals can be venomous in the manner of snakes and lizards. However, it was first demonstrated scientifically 50 years ago in the case of the American short-tailed shrew. Subsequently, similar evidence has been obtained from European shrews and the Haitian solenodon, but research in this area has been almost ...

Of the approximately 4,200 species of mammals inhabiting the earth, few are singularly adapted for existence in wetland environments. Yet wetland habitats provide important resources for many mammals that occupy broad ecological niches but are typically associated with other habitat types.

Mammals of Assam and the Mammal-Geography of India
1974The northeastern parts of India, comprising Assam, are of exceptional biogeographical interest. It is from this region that the obliteration of the Pre-Tertiary Tethys Sea began, producing in its wake a land connection between the Indian Peninsula and the main Asiatic mass to its north (see Chapters II, III & XX).
