Erratum     
The Table of Contents in the January 1997 issue, AJPA 102:1, did not differentiate between articles published as part of an edited symposium, and other research papers published in that issue. Five of the first six articles (pp. 1-77) in volume 102:1 were originally presented at the 63rd AAPA annual meeting (1994) as part of a symposium entitled “Social and Political-Economic Perspectives in Biological Anthropology.” The organizers of the symposium, and its counterpart published in AJPA 102:1, were T.L. Leatherman and A.H. Goodman.  相似文献

Foreword     
The Eighth International Symposium on Tardigrada was hosted by the Department of Invertebrate Zoology, Zoological Museum, University of Copenhagen and held at the August Krogh Institute from 30 July to 5 August 2000. There were 65 participants at the symposium. Like its predecessors, the symposium presented oral presentations and posters on a wide variety of tardigradological themes, and several invited speakers gave special keynote lectures about molecular biology, computer cladistics, phylogeny, cryptobiosis and palaeontology. Fifty four abstracts were published in the “Booklet of Abstracts” edited by Jesper G. Hansen. The 41 papers appearing in this special issue of Zoologischer Anzeiger represent most of the contributions presented in Copenhagen. Furthermore, a workshop on Arctic Tardigrades was held at Danish Arctic Station, Qeqertarsuaq, Greenland from, 7 to 18 August 2000. There were 15 participants on this Greenlandic Adventure.  相似文献

Biological distance analysis, the dominant type of skeletal biological research during the 19th century, has become less visible in recent years. Although the proportion of American Journal of Physical Anthropology articles and published abstracts focusing on biodistance has remained fairly constant over the three decades between 1955 and 1985, the proportion of biodistance contributions relative to other skeletal biology studies has decreased. Emphasis in skeletal biology has shifted from the analysis of biological variation to investigations of health and diet, and within biodistance studies methodological issues have assumed prominence over purely analytical approaches. This paper investigates trends in biological distance analysis through a survey of articles and meetings abstracts published in the American Journal of Physical Anthropology from 1955 to 1985. The survey provides the historical context for five symposium papers on skeletal biological distance presented at the 1986 meeting of the American Association of Physical Anthropologists.  相似文献

In this study we asked whether growth hormone (GH) and one of its key mediators, insulin-like growth factor I (IGF-I), influence spinal motoneuron size in conjunction with whole body size. We present evidence that GH has such a role, possibly without the mediation of IGF-I. Both lumbar motoneuron and body size were found to be increased relative to littermate controls in transgenic mice overexpressing GH, while body size, but not motoneuron size, was increased in mice overexpressing IGF-I. GH overexpression coordinately increased nucleolar, nuclear, and cell body size in lumbar spinal motoneurons, so that their normal size relationships were preserved in the transgenic mice. In addition, spinal cord and brain weights were significantly increased in both types of transgenic animal. We conclude that GH can regulate motoneuron, central nervous system, and body size in the same animal, and that IGF-I can mimic the effects of GH on at least two of these three parameters. © 1997 John Wiley & Sons, Inc.

An index of coat condition can be a non‐invasive tool for tracking health and stress at population level. Coat condition in ringtailed lemurs, Lemur catta, was recorded during September–November birth seasons of 1996, 1997, 1999, and 2001–2006 at Berenty Reserve, Madagascar. Condition was scored on a scale from 0: full, fluffy coat with guard hairs present, to 5: half or more of body hairless. Adult males did not differ overall from adult females. Coats were worse in adults than in 2‐year‐old subadults; 1‐year‐old juveniles were intermediate. Mothers and adult males lost coat condition as the season progressed: non‐mother females maintained condition. Years 1999–2002 scored better coats than either 1996–1997 or 2003–2006. Lemurs in high population density areas had worse coats than in natural forest, but tourist presence had less effect than density. Monitoring coat condition in an apparently healthy population reveals differences between population segments, and in a forest fragment with limited immigration or emigration it can track progressive changes, correcting impressions of progressive improvement or degradation over time. Above all it gives a baseline for response to climate changes or eventual pathology. Am. J. Primatol. 71:191–198, 2009. © 2008 Wiley‐Liss, Inc.  相似文献

The objective of the study was to develop a method for artificial insemination (AI) in the common marmoset, a New World primate species. For AI to be successful, sperm must be deposited at an appropriate site and time in the female reproductive tract, details of which are currently not available for Callitrichid species. Epididymal sperm were deposited in the cervix of 18 marmoset monkeys (Callithrix jacchus) around the time of expected ovulation using either 3, 2, or 1 inseminations. Six out of 18 females conceived, resulting in the first reported births following AI in this species. These pregnancies show that the presence of coagulum in the vagina and the stimulus of the female reproductive tract by natural mating are not essential for effective sperm transport in this species. Although 3 different timing regimes for sperm deposition relative to ovulation were employed, no protocol was demonstrably better than the others in terms of number of conceptions. The proportions of motile, live, and morphologically normal sperm in the suspensions used for AI were comparable with published values for ejaculates from fertile male macaques. These preliminary results indicate that births are possible following AI in marmosets: the technique could be used to aid effective genetic management of the species and possibly to facilitate captive breeding of endangered Callitrichids.

In many viviparous vertebrates, pregnant females sustain their developing embryos and provide them with nutrients by means of placentas and a diversity of other types of specializations. With this article, we introduce a virtual (online) issue of the Journal of Morphology that presents 12 recent papers on fetal maintenance in viviparous vertebrates. We also outline the history of research in this area and document the central role of morphology in helping to explain the function and evolution of specializations for fetal nutrition. This virtual issue of the Journal of Morphology is an outgrowth of a symposium held under auspices of the International Congress of Vertebrate Morphology. The included papers reflect a diversity of taxa, research methods, and biological issues. To celebrate the publication of this virtual issue of the Journal of Morphology, the publisher is making freely available to readers a number of other relevant papers published in the journal over the past 128 years.

Samadder, P., Xicohtencatl-Cortes, J., Saldaña, Z., Jordan, D., Tarr, P.I., Kaper, J.B., & Girón, J.A. The Escherichia coli ycbQRST operon encodes fimbriae with laminin-binding and epithelial cell adherence properties in Shiga-toxigenic E.coli O157:H7. Environmental Microbiology, 11, 1815–1826. https://doi.org/10.1111/j.1462-2920.2009.01906.x The above article, published online 1 July 2009 on Wiley Online Library ( wileyonlinelibrary.com ), has been retracted by agreement between the authors, the journal Editor-in-Chief, Applied Microbiology International and John Wiley & Sons Ltd. The retraction has been agreed due to concerns raised by a third party regarding the appearance of Figures 2 and 7. Figure 7D appears to be digitally manipulated while Figure 7F is a duplication of Figure 2, Lane 4. The raw data were not available upon request. As a result, the data and the conclusions are considered unreliable.  相似文献

We report the first quantitative ultrastructural analysis of newly formed acetylcholine receptor aggregates. Aggregates were induced in Xenopus muscle cell cultures with agrin, labeled with gold particles, and detected using high resolution scanning electron microscopy. Aggregates are readily discernible at the ultrastructural level within 2 h of stimulation by agrin. The size and density profiles of the developing aggregates show that receptors reach maximal density very quickly in small “nano-aggregates” and that the aggregation process is not limited by the diffusion rate of the receptor. Quantitative analysis of label locations indicates that the receptor distribution within aggregates is nonrandom. Instead, the newly aggregated receptors appear to be bound to a localized scaffold conforming to a hexagonal (close-packed) geometry with a spacing of approximately 9.9 nm. © 1997 John Wiley & Sons, Inc.
