We describe here two new species of oegopsid squids. The first is an Asperoteuthis (Chiroteuthidae), and it is based on 18 specimens. This new species has sucker dentition and a funnel–mantle locking apparatus that are unique within the genus. The second new species is a Promachoteuthis (Promachoteuthidae), and is based on a unique specimen. This new species has tentacle ornamentation which is unique within the genus. We also describe a new genus and a new species of sepioid squid in the subfamily Heteroteuthinae (Sepiolidae) and it is based on four specimens. This new genus and species exhibits unique modifications of the arms in males.  相似文献

Anticipating a complete revision of the genus Xanthophyllum , which will be printed in Blumea within two years, one new subgenus, 17 new species, one new subspecies and two new varieties are described, and for three names a new status is proposed. This is done for nomenclatural reasons, validating the new names in W. C. Dickison's study of the leaf anatomy of Xanthophyllum , published elsewhere in this Journal.  相似文献

On prediction of genetic values in marker-assisted selection.   总被引:13,自引:0,他引:13  
C Lange  J C Whittaker 《Genetics》2001,159(3):1375-1381
We suggest a new approximation for the prediction of genetic values in marker-assisted selection. The new approximation is compared to the standard approach. It is shown that the new approach will often provide substantially better prediction of genetic values; furthermore the new approximation avoids some of the known statistical problems of the standard approach. The advantages of the new approach are illustrated by a simulation study in which the new approximation outperforms both the standard approach and phenotypic selection.  相似文献

强直性脊柱炎(Ankylosing spondylitis, AS)是以骶髂关节和脊柱病变为主的炎性疾病。其特征性病理表现为炎症和新骨形 成。近年来使用肿瘤坏死因子(Tumor necrosis factor,TNF)抑制剂控制AS 炎症已卓有成效,却无法阻止影像学进程,其病理性新 骨形成可致残,严重影响患者健康生活,但其机制尚不完全清楚。目前研究认为复杂的新骨形成机制与Wnt/beta-catenin信号通路及 其调控因子、炎症介质密切相关。本文结合当前国内外的研究就AS 新骨形成机制进展展开综述,为深入研究新骨形成机制提供 新思想。  相似文献

麻竹不同造林方式对当年新竹生长的影响   总被引:2,自引:0,他引:2  
994~1996年在福建南靖县进行麻竹(DendrocalamuslatiflorusMunro)扦插苗造林和移栽母竹造林试验,扦插苗造林发笋数比移栽母竹造林发笋数多025个/丛,新竹直径大121cm。扦插苗造林后,当年萌动新竹越多,新竹直径呈增大的趋势,随着新竹萌发的先后顺序,扦插苗造林的新竹平均直径也有相应增大的趋势。移栽母竹造林当年,新竹的大小受新竹数和母竹直径的影响显著,新竹直径与母竹直径呈正相关,新竹越多,新竹直径呈减小的趋势,其新竹平均直径随萌发先后也呈依次减小的趋势。  相似文献

A review is presented of the history and recent trends in the exploration and development of food plants in southern Africa. The opportunities for developing new crops and new products for local and international markets are discussed. More than 120 species with potential as new food and beverage products (including functional foods, herbal teas and new flavours) are listed and a subjective rating of the commercial potential is provided for each of them. Some noteworthy examples are discussed and illustrated, including several indigenous fruits and vegetables that are as yet poorly known. There is a growing awareness of the importance of indigenous plants in new product development and numerous new products are already being developed. Basic research in botany (to guide genotype selection), horticulture (to develop new crops), food science (to focus on nutritional analyses) and marketing (to understand and develop new marketing approaches) is mentioned as important priorities.  相似文献

In anticipation of the publication of full revisions, a diagnosis of a new species of Droguetia is presented together with two new combinations for subspecies of Droguetia iners , a new combination for a species and a variety on Didymodoxa and a new combination for a subspecies of Australina pusilla . The name Elatostema trinerve Hochst. (1845) is shown to be conspecific with and antedate Urera cameroonensis Wedd. (1869). The new combination Urera trinervis is therefore made.  相似文献
