查询词典 type species

On the other hand,there has been so far no mapping method and software that can be used to map dominant-recessive markers obtained from F2 population of lepidopteran species.To resolve this problem,two-point and three-point maximum likelihood methods for mapping dominant-recessive markers using F2 population of this type of species were developed in this paper.At,the same time:we also gave a general method for constructing the gene linkage map of this type of species using F2 population.

另外，目前还没有任何方法和软件可以用杂交F2群体来作图鳞翅目类昆虫，如家蚕等连锁图谱，为了解决这一问题，本文发展了用F2群体作图这类昆虫连锁图谱的两点和三点极大似然法，同时还给出了大群体作图形态基因连锁图谱的一般方法。

There were 22 pollinating insect species belonging to 4 orders and 11 families, among which, native bee species Megachile abluta, M. spissula, Xylocopa valga, Andrena parvula and Anthophora melanognatha were the main pollinators. M. abluta, M. spissula and X. valga were of uni-peak type with diurnal foraging activities trom 11:30 to 15:30, while A. parvula and A. melanognatha were of double-peak type with diurnal foraging activities on 9:30-11:30 and 16:30-18:30, indicating a complementary relationship among the pollinators. The main pollinators had significant differences in their tripping frequency and landing time, and their foraging behaviors were correlated with their body sizes.

结果表明：苜蓿访花昆虫共计22种，分别属于4个目，11个科，根据弹花效率初步确定鳞地蜂、黑颚条蜂、净切叶蜂、细切叶蜂和紫木蜂为河西地区主要传粉昆虫；主要传粉昆虫的日活动规律出现单峰型和双峰型2种，净切叶蜂、细切叶蜂和紫木蜂属于前者，只在11：30-15：30出现一个活动高峰，而鳞地蜂与黑颚条蜂则为双峰型，在9：30-11：30和16：30-18：30分别出现访花高峰，不同的传粉昆虫之间存在互补关系；主要传粉昆虫的弹花频率和小花停留时间存在显著差异，且访花行为与野生蜂体型紧密相关。

The representative families are Dryopteridaceae, Athyriaceae, Polypodiaceae, Thelypteridaceae, Selaginellaceae and Aspleniaceae. The main genera are Dryopteris, Selaginella, Asplenium, Arachniodes, Pteris, Allantodia and Plagiogyria. The top families' distribution types are cosmopolitan and pantropic ones, the main genera are pantropical ones, while species distribution type belong to the east Asia type and represents the feature of subtropics transition to warm temperated areatype. As for the order of closeness, the sequence of pteridophytes floristic relations between Songyang and the adjacent regions goes as Southwest China, South China, Central China, Japan, North China, Northwest China and Northeast China. The six upland pteridophytes next to Songyang can be put into the same natural flora because of its closest relationship. But compared with other 11 upland fern flora in China, fern in Songyang is not rich enough. There are 37 species endemic to China in Songyang.
