title: Variations of collembolan communities in drained and diked salt marsh and adjacent farmland in coastal Southeastern China

description: Drained and diked salt marshes (DDSM) habitats, a typical form of coastal
 wetland, are undergoing ecological recovery, offering valuable insights
 into strategies for restoring and protecting biodiversity in reclaimed
 coastal wetlands. Richness, abundance, and composition of the collembolan
 community is expected to vary in response to changes in plant and soil in
 DDSM habitats and agricultural farmlands. However, knowledge on these
 variations remains limited. Therefore, we aimed to reveal the
 species richness, abundance, and composition of the collembolan community
 and the effect exerted by plant and soil variables in DDSM and
 agricultural farmlands. Soil samples were collected
 in coastal DDSM (northern enclosure and
 southern enclosure) and wheat farmland areas in Ningbo City, southeastern
 China, in April 2023. Species richness, rather than abundance, of the
 collembolan community, was significantly lower in DDSM habitats than in
 wheat farmlands. The collembolan community composition differed
 significantly between these two habitats. Ceratophysella
 skarzynskii Weiner (1996), Desoria sp12, Isotoma
 pinnata Fabricius (1781), and Sinella sp. were
 exclusively in DDSM habitats. Instead, the genera Arrhopalites,
 Heteraphorura, and Parisotoma preferred wheat farmlands. Plant
 coverage and height were important variables affecting collembolan
 community composition in DDSM habitats. DDSM habitats can sustain specific
 collembolan species, and their soil biodiversity warrants attention,
 particularly following rigorous reclamation measures. This study provides
 important information for restoring and protecting biodiversity in
 reclaimed coastal wetlands.
description: <em>Data Collection</em> Soil
 samples were collected in April 2023 from two types of habitats in Ningbo
 City, southeastern China: (1) drained and diked salt marshes (DDSM),
 including the northern enclosure and southern enclosure, and (2) adjacent
 wheat farmlands. Ten plots were selected to represent typical ecological
 conditions of each habitat. At each plot, three soil samples were
 collected to capture soil Collembola. Collembolan communities were
 extracted from the soil samples using Tullgren method, and species
 richness, abundance, and composition were recorded. Additionally, plant
 coverage and height were measured at each plot to assess their potential
 influence on collembolan communities. <em>Data
 Processing</em> The collected soil samples were
 processed in the laboratory to extract and identify collembolan species.
 Species identification was conducted using morphological characteristics
 under a microscope, following established taxonomic guidelines. Data on
 species richness, abundance, and community composition were compiled and
 analyzed. Plant and soil variables (e.g., plant coverage, height) were
 recorded and included in the dataset to assess their relationship with
 collembolan community dynamics. Statistical analyses were performed to
 compare collembolan communities between DDSM habitats and wheat farmlands,
 and to identify key environmental variables influencing community
 composition.
