Infanticide: Comparative and Evolutionary Perspectives by Glenn Hausfater

By Glenn Hausfater

contemporary box experiences of a number of mammalian species display an incredibly excessive frequency of infanticide - the killing of unweaned or in a different way maternally established offspring. equally, reports of birds, fish, amphibians, and invertebrates display egg and larval mortality in those species, a phenomenon at once analogous to infanticide in mammals. during this assortment, Hausfater and Hrdy draw jointly paintings on animal and human infanticide and position those experiences in a large evolutionary and comparative perspective.Infanticide provides the theoretical heritage and taxonomic distribution of infanticide, infanticide in nonhuman primates, infanticide in rodents, and infanticide in people. It examines heavily intercourse allocation and intercourse ratio thought, surveys the phylogeny of mammalian interbirth periods, and reports info on resources of egg and larval mortality in quite a few invertebrate and reduce vertebrate species. facing infanticide in nonhuman primates, chapters significantly research facts on infanticide in langurs and its broader theoretical implications. via reviewing resources of boy or girl mortality in populations of small mammals and new laboratory analyses of the motives and outcomes of infanticide, this paintings explores such concerns because the ontogeny of infanticide, proximate cues of babies and women which elicit infanticidal habit in men, the genetical foundation of infanticide, and the hormonal determinants.Hausfater and Sarah Blaffer Hrdy, via their number of fabrics for this e-book, evaluation the frequency, motives, and serve as of infanticide. old, ethnographic, and up to date info on infanticide are surveyed. "Infanticide" summarizes present examine at the evolutionary origins and proximate causation of infanticide in animals and guy. As such it will likely be critical examining for anthropologists and behavioral biologists in addition to ecologists, psychologists, demographers, and epidemiologists.

Gliomas: Current Concepts in Biology, Diagnosis and Therapy by J. Hekmatpanah

By J. Hekmatpanah

while i used to be requested by way of the melanoma educating Committee of the college of Chicago to establish a Symposium on mind Tumors, I welcomed the chance to take action. yet I felt that "Brain Tumors" used to be a ways too huge a subject matter to hide in an afternoon and a part assembly. moreover, up to now decade, there were a very good many papers and symposiums on technical developments within the therapy of benign mind tumors. however, whereas gliomas make up someplace round 50% of all mind tumors, there have definitely been a ways fewer communications approximately them. accordingly i presumed that it might be hugely important to ask many of the prime investigators to percentage with us their adventure with gliomas. The wish used to be to profit the present recommendations approximately those tumors biologically and therapeutically, particularly to determine what we're doing and the place we're entering into those respects. certainly all facets couldn't be coated. however, it was once a greatly expressed opinion by way of the audio system that they too realized whereas they got here to coach. it truly is as a result was hoping that the booklet in their works and concepts via this mono­ graph can also be helpful for the reader. lots of the manu­ scripts have been passed in on the time of the Symposium, and some have been despatched later. apart from minor editorial alterations the phrases are completely these of the audio system and authors.
