群落

A field experiment on the reproductive allocation of the annual plant Eragrostis poaeoides was carried out in the re-vegetated areas in Shapotou of the Tengger Desert.

繁殖是生命得以延续的唯一手段，它不仅是种群形成、发展和进化的核心问题之一，也是生物群落和生态系统演替的基础。

Most of the secondary forests in Zhuhai are dominated by the species of Lauraceae, Euphorbiaceae, and Theaceae. There are also many tropical taxa of Rubiaceae, Myrtaceae, and Moraceae.

珠海市的森林群落以樟科、大戟科和山茶科植物最为丰富，茜草科、桃金娘科和桑科等热带植物种类也比较丰富。

Dominant species were scrutinized, of which 8 species in spring, 7 in summer, 9 in autumn and 13 in winter. All the dominant species were eurythermic and euryhaline characteristic of sub-tropic community structure along seashore. The majority of dominant species were Thalassiosira pacirica , Skeletonema costatum , Nitzschia paradoxa , and Thalassiosira subtilis .

优势种共有37 种：春季8 种、夏季7 种、秋季9 种、冬季13 种，几乎全为广温广盐性沿岸种类，群落结构具有亚热带和沿岸性特征，主要优势种为太平洋海链藻 Thalassiosira pacirica 、中肋骨条藻 Skeletonema costatum 、奇异菱形藻 Nitzschia paradoxa f。

The results showed that intercropping with faba bean changed the ammonia-oxidizer community composition in Rhizosphere of wheat.

利用DGGE技术研究了不同间作和轮作种植体系对作物根际氨氧化细菌和固氮菌群落结构的影响。

A total of 26 tree species (DBH≥3.0cm) were recorded within 5 plots in the forest, which belong to 15 families and 21 genus. Fagaceae and Hamamelidaceae were dominant families. The vertical structure of the forest was simple, without obvious shrub and herb layers.

结果表明，5块样地内共出现树种26种，分属于15科21属，以壳斗科和金缕梅科为主；群落垂直结构简单，灌木层和草本层不甚明显。

Mainly Lauraceae, Fagaceae, Theaceae, magnolia Branch, Division of Hamamelidaceae evergreen broad-leaved trees such as the composition of the shrub layer are found to evergreen species, community structure is more complex.

主要由樟科、壳斗科、山茶科、木兰科、金缕梅科等科的常绿阔叶树组成，灌木层中亦多常绿种类，群落结构比较复杂。

The fruiting bodies of ectomycorrhizal fungi were abundant and diverse in intact forest dominated by Fagaceae. Only a few species of macrofungal bodies were found in the pine dominated forest and secondary broad-leaved forest and none were seen in grassland during the study.

外生菌根菌子实体在以壳斗科植物为优势种的原生性次生林中较多且种类丰富，在松林和次生阔叶林有少数种类，但次生草坡群落未见有外生菌根菌子实体。

Faunal assemblage are directly related to the depositional environment.

动物群落与沉积环境有直接关系。

Interactions between fertilizer addition, plants and the soil environment: Implications for soil faunal structure and diversity.

随着研究的深入发展，土壤动物群落生态学研究将不断与农业生态、环境生态、城市生态和恢复生态等应用生态学领域结合。
