描述----------Description----------

A dataframe in standard format due to Migliorini and Caruso presenting observations of oribatid mites.
一个数据框的标准格式,由于米廖里尼和卡鲁索甲螨观察。


用法----------Usage----------


data(caruso)



格式----------Format----------

Dataset caruso is a data frame with 194 observations on 5 variables.  Each row corresponds to a species; the observations (rows) are the species abundances in each of 5 habitats.
数据集caruso是一个数据框有194对5个变量的观察。每一行对应于一个物种的意见(行)5栖息地的物种丰度。

Following Migliorini et al 2002, the habitats were:
米廖里尼等人2002年之后,生境:

a pure beech woodland ("Beech")
一个纯粹的山毛榉林地(Beech)

a coppice woodland ("Coppice")
一个萌芽更新林地(Coppice)

grassland ("Grassland")
草原(Grassland)

heathland ("Heathland")
石楠(Heathland)

"Biancana" badlands ("Biancana")
“Biancana荒芜之地(Biancana)

详细信息----------Details----------

Oribatid mites are rather small and very interesting free living soil microarthropods.  They have a huge species diversity with populations characterised by highly aggregated distributions over multiple spatial scales ranging from a few centimetres to hundreds of meters.
甲螨是相当小的,非常有趣的生活土壤microarthropods。他们有一个巨大的物种多样性与族群,由高度集中的分布在多个空间尺度上,从几厘米到几百米不等。

Within each habitat, several soil samples were collected (five randomly located replicates per each month: see the paper Migliorini et al. 2002). So, actually, that is a network of small samples that make a single large sample.
在每个栖息地,土壤样品采集(每月的5个随机分布复制每米廖里尼等人的论文,2002年)。因此,实际上,这是一个网络,使一个单一的大样本的小样本。

The five study areas of this data set belong to five habitats that are very typical of that Mediterranean region.  These five areas also belong to a rather homogeneous biogeographical region (southern Tuscany).  On the ground of what is known on the biology and community patterns of Oribatida, several a-priori hypotheses can be made on expected changes in the diversity of their assemblages and immigration rates respectively between and within the five areas.  For instance, under the Neutral Model one might expect that the Beech forest should have the highest Theta and an immigration rate of about 1, while one might expect the opposite for the Biancana (a very arid habitat, a kind of gariga/garrigue with very patchy vegetation).
这组数据的五个研究领域属于5种生境,地中海区域是非常典型的。这五个领域还属于一个比较均匀的生物GEO区域(南托斯卡纳)。什么是已知的甲螨的生物学和社会模式,在地面上,一个先验的假设,可以预期变动的多样性之间的组合和移民率分别在五个方面。例如,在中性条件下模型中,人们可能会想到,榉木森林应具有最高的Theta和移民率约为1,而人们所预料的相反的Biancana(一个非常干燥的栖息地,种gariga /灌木丛非常斑块状植被)。
