An 1855 paper on the "introduction" of species, written by Alfred Russel Wallace, claimed that patterns in the geographical distribution of species and fossils could be explained if every new species always came into existence near an already existing, closely related species.

1855年，阿尔弗雷德·罗素·华莱士写了一篇物种"导言"的论文，声称如果每个新物种的开始存在往往总是挨近一个已经存在的、密切相关的物种，那么，物种和化石的地理分布模式就是可以解释的。

Zoo benthos species were observed,with 7 species of arthropod, species of mollusk,and species of annelid.

The result shows that in total 75.6% species are under the "10 × rule", 80.5% species possess unique DNA barcode sequences by which they could be identified. On the other hand, 19.5% species (including 8 species of Buteo) are difficult to be distinguished by DNA barcoding.

结果显示，75.6%的猛禽符合10×规则，且80.5%的猛禽均具有独特的DNA条形码可作为物种鉴定的依据，另有19.5%的猛禽（鵟属8种猛禽）由于种间差异太小，DNA条形码对它们的识别鉴定存在一定局限。

The richness center of the Theaceae plant species under study is located in the mountainous area of north Guaugdong (22.5°N, and 112~115°E). These plants species exhibited significant longitudinal difference (P=0.0012), and latitudinal variation (P=0.0049). Canonical Correspondence Analysis showed the distribution of plant species could be explained by caloric factors and moisture factors, and MAMI (mean annual minimum temperature) was the key factor determining the distribution pattern of Theaceae plant species richness in the study area.

对125种植物、72个网格和6个环境因子进行典范对应分析表明：CCA排序轴第1轴主要代表温度的变化梯度，第2轴主要代表水分的变化梯度，说明水分、温度等因素共同影响山茶科植物在广东的生长和分布，其中年均最低温度是影响广东省山茶科植物丰富度水平地带性格局的最大因子。

Altogether 24 species of helminths including 11 species of Trematoda, 9 species of Nematode, and 4 species of Cestode were found.

一个地区人畜共患寄生虫病的流行与传播，常常可以从动物种群中反映出来。

There are seven species of monkeys, including the drills; four galagos; two small antelopes; one species of porcupine; one species of tree hyrax; one species of pouched rat; and three species of scaly-tailed squirrels.

岛上聚居了来自非洲大陆的许多物种的分支种群：包括鬼狒在内的七种猴子、四种夜猴、两种小羚羊、豪猪、树岩狸、和三种尾巴上带鳞片的松鼠。

The results showed that the free-living marine nematodes were the dominant group the percentage of which in the total number of meiofauna ranging betwean 76.1%~96.3%. The abundance of meiofauna in old mangrove district was the least and in bare beach where waste water flows was the most. There were a total of 37 putative species in the samples. The total number of recorded species was the lowest in the new mangrove district, and highest in the old mangrove district. The species diversity indexes, species evenness indexes and richness indexes in old mangrove district were all higher than those in new mangrove district. The dominant species and feeding types were different in three types of habitats.

结果表明：海洋线虫是凤林红树林中小型底栖动物中的绝对优势类群，占到小型底栖动物的76.1%~96.3%；从丰度来看，旧区白骨壤林中小型底栖动物的数量较少，有污水流过的光滩数量较大；4个断面共鉴定出海洋线虫37种，其中新区秋茄林中的生物多样性指数较低，旧区白骨壤林中群落具有较高的物种多样性；从出现的物种来看，新区秋茄林、旧区白骨壤林和光滩上出现的优势种和摄食功能群的类型各不相同。

The results showed that the calorific values of the test plant species had no unified change pattern, which was possibly related to the partitioning ratio of calorific value in different plant organs and the timing when the reproductive period appeared. In general, spike had a higher calorific value than leaf and stem, and aquatic plants had obviously lower calorific value than mesophytes and wet mesophytes. Within a species, the change pattern of calorific value had certain relations to the phenophase, with approximately two lowest values and two highest values. Among the species, the differences in the calorific value were decided by the nature of the species themselves. Under the same habitat and climatic conditions, the species that contained more materials rich in energy could more easily accumulate calorific, and thus, more adaptable to grow under this environment.

结果表明：各物种的热值动态变化规律并不是统一的，这种变化可能与植物各器官热值的变化及生殖期出现的时间有关；各植物器官的热值普遍表现出穗的热值大于茎和叶；水生植物的热值明显小于中生性和湿中生性植物；种内热值变化随物候期变化有一定的规律，大约会出现2次低值、2次高值；种间热值差异是由于植物本身性质决定的，在相同生境和气候条件下，植物体中含能物质越多，就越易积聚热值，从而更适宜生长在此环境。
