Evolution, 2021
Aposematic coloration is traditionally considered to signal unpalatability or toxicity. In mammals, most research has focused on just one form of defense, namely, noxious anal secretions, and its black-and-white advertisement as exemplified by skunks.

In his theory of ageing Professor Bullough suggests that in mammals it is stress which delays cell death through its effect on the chalone mechanism.

Nature, 1953
POLYSPERMY—the entry of more than one sperm into the vitellus at fertilization—is commonly regarded as a pathological process in mammals, with the implication that it leads to early degeneration of the embryo, and this opinion has been expressed by such authorities as Lams1, Wilson2, and Hartman3.

The Quarterly Review of Biology, 1977
This review considers the behavioral, ecological, and reproductive characteristics of mammals exhibiting monogamy, i.e., mating exclusivity. From a discussion of the life histories of selected species of monogamous primates, carnivores, rodents and ungulates, several trends emerge. Two forms of monogamy occur, Type I, facultative, and Type II, obligate.

Abstract In comparison to birds, magnetoreception in mammals has been understudied. This negligence has historical and methodological causes. We summarize the paradigms that have been applied in the study of magnetoreception in mammals. We also provide an overview of mammalian taxa in which magnetoreception has been studied and indicate potential ...

Microbes and Infection, 2000
Microsporidia are small, single-celled, obligately intracellular parasites that have caused significant agricultural losses and interference with biomedical research. Interest in the microsporidia is growing, as these organisms are recognized as agents of opportunistic infections in persons with AIDS and in organ transplant recipients. Microsporidiosis

Mammals and mammal-like robots
2018Mammals are warm-blooded tetrapod vertebrates that evolved from reptilian ancestors during the late Triassic period around 225 million years ago. This chapter focuses on some of the most distinctive mammalian characteristics and on integrated robotic systems that seek to capture these capabilities in biomimetic artifacts.

Mesozoic Mammals and the Polyphyletic Origin of Mammals
Evolution, 1959This is, in one way, a poor time to review the iViesozoic mammals and the origin of mammals. Discoveries and studies announced but not yet published fully, if at all, are extraordinarily rich and important. They include: late Cretaceous mammals from Wyoming (McKenna and associates at the University of California) ; Triassic mammals or very advanced ...
