■居住在土壤表面的凋落物与土壤的有机矿物基质中的孔隙之间的空间-称为空隙。这些生物在土壤生态系统功能中起着举足轻重的作用,例如有机物的分解和分解,细菌和真菌孢子的扩散和生物栖息地的转化。这些功能,反过来,有助于更广泛的生态系统服务,如碳和养分循环,土壤有机质调控与化学和物理土壤肥力。这项研究提供了与一系列土壤生物大小有关的形态学数据,特别是在滚动潘帕斯地区农业活动水平不同的Argiudol土壤中,世界上最广阔和肥沃的平原之一。主要重点是土壤微节肢动物-即,Acari(螨虫)和Collembola(跳尾)-身体宽度小于2毫米。这些生物构成了复杂的土壤孔隙网络中的大部分生命。此外,该研究记录了蚯蚓的种类(Oligochaeta,Crassiclitelata),被公认为生态系统工程师,因为他们有能力在土壤基质中创建物理通道并分配有机物。此外,这项研究包括测量土壤居住的“大型动物”(身体宽度大于2毫米的生物)的形态特征,这也与各种土壤生态系统功能有关。这些包括顶点捕食者的人口调节,有机物分解,生物结构形成,营养动员和食草动物。
■在本文中,我们报告了7,000多个标本的地理位置和关键形态性状的个体测量,覆盖了一系列土壤生物。这些包括春尾(Entognatha,Collembola),螨虫(花生,Acari),蚯蚓(Oligochaeta,Crassiclitellata)和其他大型土壤动物。所有标本均来自位于三个不同农业系统中的典型Argiudol土壤,其特征是土地利用强度水平不同。据我们所知,没有其他数据集可以为阿根廷的Pampas提供此信息。
UNASSIGNED: Soil-dwelling organisms populate the spaces-referred to as interstices-between the litter on the soil surface and the pores in the soil\'s organo-mineral matrix. These organisms have pivotal roles in soil ecosystem functions, such as the breakdown and decomposition of organic matter, the dispersal of bacterial and fungal spores and biological habitat transformation. These functions, in turn, contribute to broader ecosystem services like carbon and nutrient cycling, soil organic matter regulation and both chemical and physical soil fertility.This study provides morphological data pertaining to a range of soil organism sizes, specifically in Argiudol soils subjected to varying levels of agricultural activity in the Rolling Pampas Region, one of the world\'s most extensive and fertile plains.The primary focus is on soil microarthropods-namely, Acari (mites) and Collembola (springtails)-with a body width of less than 2 mm. These organisms constitute the majority of life in the intricate soil pore network. Additionally, the study documents species of earthworms (Oligochaeta, Crassiclitelata), recognised as ecosystem engineers for their ability to create physical channels in the soil matrix and to distribute organic matter. Moreover, the study includes measurements of morphological traits of soil-dwelling \"macrofauna\" (organisms with a body width greater than 2 mm), which are also implicated in various soil ecosystem functions. These include population regulation by apex predators, organic matter decomposition, biogenic structure formation, nutrient mobilisation and herbivory.
UNASSIGNED: In this paper, we report both the geographical locations and individual measurements of key morphological traits for over 7,000 specimens, covering a range of soil-dwelling organisms. These include springtails (Entognatha, Collembola), mites (Arachnida, Acari), earthworms (Oligochaeta, Crassiclitellata) and additional soil macrofauna. All specimens were collected from typical Argiudol soils located in three distinct agricultural systems characterised by varying levels of land-use intensity. To our knowledge, no other dataset exists providing this information for the Argentinian Pampas.
