栖息地片段化是导致生物多样性丧失的最主要因素之一,身体大小是影响各种动物类群生活史特征、种内和种间关系等生态过程的重要的形态学特征,身体大小在空间和时间上的差异是动物普遍存在的环境适应结局。与大陆种群相比,许多动物类群的岛屿种群在形态及身体大小上会出现非常显著的变化。丁平教授课题组基于“岛屿规律”和动物形态快速进化等研究背景,以千岛湖片段化栖息地为研究平台,开展人类活动造成片段化栖息地中动物身体大...

A series of experiments was carried out to determine the possibility for the non-ionic surfactant (NIS) as a feed additive for ruminant animals. The effect of the NIS on (1) the enzyme distribution in...
We show that explicit mathematical and biological relationships exist among the scaling exponents and the allometric constants (a and b, respectively) of log–log linear tree-community size frequency d...
Relationships between probabilities of occurrence for fifteen diadromous fish species and environmental variables characterising their habitat in fluvial waters were explored using an extensive collec...
Two statistical modelling techniques, generalized additive models (GAM) and multivariate adaptive regression splines (MARS), were used to analyse relationships between the distributions of 15 freshwat...
Multiple-type branching processes that model the spread of infectious diseases are investigated. In these stochastic processes, the disease goes through multiple stages before it eventually disappears...
Abstract: The high-energy tail of the distribution of solute-solvent interaction energies is poorly characterized for condensed systems, but this tail region is of principal interest in determining th...
Abstract: The analysis of non-equilibrium steady states of biochemical reaction networks relies on finding the configurations of fluxes and chemical potentials satisfying stoichiometric (mass balance)...
Recent developments in extracting and processing biological and clinical data are allowing quantitative approaches to studying living systems. High-throughput sequencing, expression profiles, proteomi...
Commonly observed patterns typically follow a few distinct families of probability distributions. Over one hundred years ago, Karl Pearson provided a systematic derivation and classification of the c...
Distribution patterns of stress-tolerant coral symbionts suggest that maximum habitat temperatures can drive local scale adaptation of symbiont populations, but at regional scales other processes ca...
摘要 利用PCR技术和复合电泳银染技术检测奶牛和肉牛BM2113、BM1862、BMc701、BM2934、TGLA122、BM720等6个STR基因座的多态性分布,并计算该6个基因座的基因频率(Pi)、个体鉴别力(DP)、杂合度(H)、多态信息含量(PIC)、和非父排除概率(PE)。结果显示:6个STR基因座的基因型分布符合Hardy-Weinberg平衡,奶牛中6个STR基因座中BM2113...
利用多重PCR和四色荧光(5-FAM,JOE,NED和ROX)自动化检测技术调查上海地区汉族人群D3S1358、vWA、FGA、D8S1179、 D21S11、 D18S51、D5S818、D13S317、D7S820等9个STR基因座多态性分布并计算该9个基因座的基因频率(Pi)、个体鉴别力(DP)、无偏倚期望杂合性(H)、多态性信息含量(PIC)和非父排除概率(PE)。结果显示:9个STR基因...
