Since the pioneering efforts of Eric Denton and John Gilpin-Brown (1966), much has been learned about the buoyancy system of the chambered Nautilus. It seems timely, therefore, to evaluate critically what is known and not known about the buoyancy sys

We describe the ultrastructure of type-I salivary-gland acini in two argasid and two ixodid species. The basic cell types in the agranular or type-I acini, and their associations, are very similar in argasids and ixodids; therefore, we propose an ana

A kidney from the budgerigar (budgie, parakeet; Melopsittacus undulatus) is composed of cortical reptilian-type nephrons (without loops of Henle) and mammalian-type nephrons (with loops) grouped together in medullary cones. The loop of the mammalian-

Our observations of wintering house sparrows ( Passer domesticus ) feeding on cracked corn at feeders placed at different distances from a brushpile and in positions differentially exposed to the wind supported the hypothesis that where food patches

Physiological changes associated with pronounced capture stress in freshwater drum (Aplodinotus grunniens) were studied. Increasing the exposure of exercised freshwater drums to low-oxygen water resulted in increasing degrees of skin reddening and pa

The chamber formation cycle in externally shelled, chambered cephalopods consists of mural ridge formation, secretion of the siphuncular connecting ring, septal calcification, and cameral liquid removal. Radiographic observation of the chamber format

The siphuncle of the chambered nautilus (Nautilus spp) can transport cameral liquid against osmotic pressure gradients, and is presumed to be able to transport against hydrostatic pressure gradients. It is hypothesized that the mechanism of such tran
