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

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 collembo..., Data Collection
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.
Data Processing
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 communit..., , # Variations of collembolan communities in drained and diked salt marsh and adjacent farmland in coastal Southeastern China
