为了解决羊体尺参数测量中存在的测量困难、应激反应、人畜共患病等问题,寻找体尺参数测点显得尤为重要。试验基于图像对测点检测开展研究。首先,通过多尺度Retinex算法增强羊体图像;然后,利用图割算法识别羊体信息,并优化羊体轮廓;接着,提取羊体的包围盒,并划分为相等的4个区域,依据测点特征依次寻找7个测点;最后,基于测点计算羊体长、体高、臀高、胸深等4个参数。结果表明:体长、体高、臀高、胸深的相对误差分别为2.10%、2.05%、1.70%、0.81%,精度较高。这说明试验方法能够克服传统中存在的测量问题,实现零接触的羊体尺参数的获取,为羊生长发育及评估提供了可靠、快速和精准的信息。

Based mainly on TOGA-COARE data, that is, the CTD data from R/V Xiangyanghong No. 5 (Pu et al., 1993), the temperature and current data from the Woods Hole mooring and other deep current data, the layered numerical profiles of buoyancy frequency and mean current components are figured out. A numerical method calculating internal wave dispersion relation without background shear current, used by Fliegel and Hunkins (1975), is improved to be fit for the internal wave equation with mean currents and their second derivatives. The dispersion relations and wave functions of the long crested internal wave progressing in any direction can be calculated conveniently by using the improved method. A comparison between the calculated dispersion relation in the paper and the dispersion relation in GM spectral model of ocean internal waves (Garret and Munk, 1972) is performed. It shows that the mean currents are important to the dispersion relation of internal waves in the western equatorial Pacific Ocean and that the currents make the wave progressing co-directional with (against) the currents stretched (shrink). The influence of the mean currents on dispersion relation is much stronger than that of their second derivatives, but that on wave function is less than that of their second derivatives. The influences on wave functions result in the change of vertical wavenumber, that is, making the wave function stretch or shrink. There exists obvious turning depth but no significant critical layer absorption is found.

Aims Much recent theory has focused on the role of neutral processes in assembling communities,but the basic assumption that all species are demographically identical has found little empirical ***,we show that the framework of the current neutral theory can easily be generalized to incorporate species differences so long as fitness equivalence among individuals is maintained through trade-offs between birth and *** Our theory development is based on a careful reformulation of the Moran model of metacommunity dynamics in terms of a non-linear one-step stochastic process,which is described by a master *** Findings We demonstrate how fitness equalization through demographic trade-offs can generate significant macroecological diversity patterns,leading to a very different interpretation of the relation between Fisher’s a and Hubbell’s fundamental biodiversity *** model shows that equal fitness(not equal demographics)significantly promotes species diversity through strong selective sieving of community membership against high-mortality species,resulting in a positive association between species abundance and per capita death *** important implication of demographic trade-off is that it can partly explain the excessively high speciation rates predicted by the neutral theory of the stronger *** equalization through demographic trade-offs generalizes neutral theory by considering heterospecific demographic difference,thus representing a significant step toward integrating the neutral and niche paradigms of biodiversity.

为保护中国特有种多鳞杜鹃,调查了多鳞杜鹃群落的生境状况、物种组成、生活组成、结构特点和物种多样性分析。结果表明,多鳞杜鹃分布范围广,分布在海拔1 800 m~3 200 m区域,为林内生态幅度较宽的植被类型。三个不同海拔梯度多鳞杜鹃群落共分布22科、35属、47种植物。多鳞杜鹃有多种生活型植物组成,其中以高位芽植物和地上芽植物为主,从垂直结构看,多鳞杜鹃群落分布有乔、灌、草层,分层现象明显,多鳞杜鹃和丰实箭竹为灌木层优势种。多鳞杜鹃群落以草本层的生物多样性最高,在高海拔区域乔木层的优势种明显随海拔降低呈降低趋势。不同海拔梯度下多鳞杜鹃群落各项多样性指数表明多鳞杜鹃群落各层次的物种丰富度指数、多样性指数、优势度指数、均匀度指数均表现出草本层>灌木层>乔木层一致性特征。物种多样性与物种丰富度成正比,物种多样性越高代表群落稳定性越好。
