Dream Interpretation in Ancient Civilizations

Dream interpretation was regarded by ancient peoples in Mesopotamia, Egypt, Greece, and Rome as an art requiring intelligence and, sometimes, divine inspiration. It became a motif in literature. It was treated as a science by philosophers and physicians. Dreams were thought to come either as clear messages, or as symbols requiring interpretation. In a method called incubation, the dreamer could sleep in a sacred place in expectation of a dream that would elucidate a problem for which the dreamer desired guidance. Dream-books listing images and their meanings were popular. Historians reported leaders' famous dreams that affected the course of events. Very few ancient writers were skeptical of dreams; Cicero was one. Dream interpretation was an honored profession with exponents such as Artemidorus of Daldis. Ancient dream traditions and beliefs can provide perspective for consideration of more recent theories of dream interpretation.

Intestinal capillariasis in New World monkeys

Two cases of intestinal capillariasis have been identified at necropsy in a squirrel monkey and a capuchin monkey born and raised in captivity. The parasites are described as far as possible from the histopathological slides or intestinal contents, and their relationship to other intestinal capillarids, especially those of primates, is discussed.     

Paternal Care in New World Primates

Extensive parental care is well developed in several generaof New World primates (genera aCallicebus, Aotus, Callimico,Calltthrix, Cebuella, Leontopithecus, Saguinus) including mostof the indirect and direct paternal care behaviors describedby Kleiman and Malcolm (1981). Paternal care is correlated witha monogamous (and perhaps polyandrous) mating system and a smallgroup size. Additionally, in genera (e.g., Callithrix) whichhave a higher reproductive rate and tolerate a larger groupsize, subadult and juvenile offspring of the breeding pair andperhaps unrelated individuals may contribute substantially tothe rearing of infants. Both within and across genera, there is considerable variabilityin the type, quantity, and distribution of care provided bythe mother, father, and other individuals in the family group.The purpose of this presentation is to examine the basis ofthis variability and to evaluate the degree to which we canmake statements about the evolution of paternal care in thisprimate radiation. There are few field studies of those species of monogamous NewWorld primates which exhibit extensive paternal care. Thus,it is currently impossible to correlate the observed variabilityin paternal care with ecological factors. Also, the taxonomyof the New World primates is in flux which makes phylogeneticinterpretation difficult (Rosenberg, 1981). As a result, thefollowing discussion will be based mainly on results from captivestudies, and will be concerned with defining those factors thatcreate variability in observed levels of paternal care, bothwithin and across genera.     

Endocrine neoplasia in New World primates

Abstract: Of 1,106 New World primates necropsied from the National Zoological Park (Washington, D.C.) and the Department of Comparative Pathology, Johns Hopkins University School of Medicine (Baltimore, Maryland) 22 (1.9%) animals were identified with 27 neoplasms. Of this group, nine animals (two females, seven males) had a total of 13 endocrine neoplasms. All animals were adults, with an age range of 2.7–25 years (average, 12.1 years). Seven were Callitrichidae and two were Cebidae. The adrenal gland was the most affected organ, with seven (53.8%) neoplasms, followed by the pituitary and thyroid gland with two (15.4%) cases each, and the pancreas and parathyroid gland with one tumor (7.7%) each. All neoplastic disorders were benign. Immunocytochemistry assays for growth hormone, adrenocorticotropic hormone, prolactin, follicle-stimulating hormone, luteinizing hormone, thyroid-stimulating hormone, and chromogranin A were performed on two pituitary neoplasms. Pheochromocytoma was the most frequent neoplasm, representing 5 (38.4%) of the 13 neoplasms. The remaining were thyroid cystadenoma (two, 15.4%), corticotrophic cell pituitary adenoma (two, 15.4%), adrenal ganglioneuroma (one, 7.7%), adrenal cortical adenoma (one, 7.7%), parathyroid chief-cell adenoma (one, 7.7%), and pancreatic islet-cell adenoma (one, 7.7%).     

Hybridization in large-bodied New World primates

Well-documented cases of natural hybridization among primates are not common. In New World primates, natural hybridization has been reported only for small-bodied species, but no genotypic data have ever been gathered that confirm these reports. Here we present genetic evidence of hybridization of two large-bodied species of neotropical primates that diverged approximately 3 MYA. We used species-diagnostic mitochondrial and microsatellite loci and the Y chromosome Sry gene to determine the hybrid status of 36 individuals collected from an area of sympatry in Tabasco, Mexico. Thirteen individuals were hybrids. We show that hybridization and subsequent backcrosses are directionally biased and that the only likely cross between parental species produces fertile hybrid females, but fails to produce viable or fertile males. This system can be used as a model to study gene interchange between primate species that have not achieved complete reproductive isolation.     

Density compensation in New World bat communities

Understanding the role of competitive interactions in shaping the structure of communities has been one the most unrelenting challenges to ecology. Traditionally, competitive interactions were assumed to be the most important agent of deterministic structure, with overdispersed morphological patterns based on body size and trophic status as their hallmark. However, models of community organization based solely on morphology have yielded only equivocal results for many taxa. Fortunately, morphological patterns may not be the only indications of competitively induced deterministic structure. Herein, we explore the degree to which the structure of five feeding guilds (aerial insectivores, frugivores, gleaning animalivores, molossid insectivores, and nectarivores) from 15 New World bat communities reflects density compensation. Nonrandom associations between abundance and morphological distance were detected in five communities, in three feeding guilds, and with respect to four competitive scenarios. Nonetheless, patterns consistent with the hypothesis of density compensation were neither pervasive nor consistent in New World bat communities. Competitively induced community structure may exist under only narrow temporal and environmental conditions, and may not be characteristic of organization in most situations.     

Origins of New World monkeys

Fossil ceboid evidence is reviewed with reference to the origins and affinities of the New World monkeys. This evidence indicates that the ceboids evolved from a North American primate of omomyid-like form. The events of continental drift apparently had little to do with the origin and dispersion of the New World monkeys and direct relationships to the Old World monkeys are not indicated. Three of the five extant New World monkey subfamilies are represented in late Miocene deposits of South America and it appears that evolutionary events leading to extant Ceboidea occurred within the South American continent.     

New World Monkeys and Color

The visual worlds of most primates are rich with potential color signals, and many representatives of the order have evolved the biological mechanisms that allow them to exploit these sources of information. Unlike the catarrhines, platyrrhines typically have sex-linked polymorphic color vision that provides individuals with any of several distinct types of color vision, including both trichromatic and dichromatic variants. In recent years, this polymorphism has been the target of an expanding range of research efforts. As a result, researchers now reasonably understand the proximate biology underlying the polymorphisms, and a number of ideas have emerged as to their evolution. Progress has also been made in illuminating how color vision capacities may be related to the particular visual tasks that New World monkeys face.
