Intensifying land use and accelerated erosion has resulted in increased delivery and deposition of fine terrestrially derived sediment to coastal ecosystems, increasing sediment mud content in estuarine ecosystems. This change in the sedimentary environment is known to have negative consequences for ecosystem functioning. Yet indirect and cyclical relationships between species and the environment are rarely investigated, despite being crucial for understanding ecosystem resilience. We investigate changes in intra- and inter-specific interactions between two key intertidal species (Austrovenus stutchburyi and Macomona liliana) with different but overlapping environmental preferences.
This dataset contains the results of a survey for Austrovenus stutchburyi and Macomona liliana at the Wairoa River estuary, Auckland, undertaken in November 2018. Results include species abundance for juveniles and adults, as well as sediment data (shell, mud, organic matter content) and microphytobenthic biomass at each core site.
The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 29 records.
2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
The table below shows only published versions of the resource that are publicly accessible.
