Abstract:

This data package is formatted as a Darwin Core Archive (DwC-A, event core). For more information on Darwin Core see https://www.tdwg.org/standards/dwc/. This Level 2 data package was derived from the Level 1 data package found here: https://pasta-s.lternet.edu/package/metadata/eml/edi/557/4, which was derived from the Level 0 data package found here: https://pasta-s.lternet.edu/package/metadata/eml/edi/556/4. The abstract below was extracted from the Level 0 data package and is included for context:

Ants comprise a considerable amount of animal biomass in terrestrial ecosystems and play major roles in ecological processes ranging from seed dispersal to soil turnover. Invasion by the hemlock woolly adelgid will transform late-successional hemlock forests into earlier successional mixed hardwood - white pine forests or red-maple wetlands. Understanding how ant assemblages vary in different habitat types allows for predictions of how hemlock decline could alter the composition of ant assemblages, with implications for a wide range of ecosystem processes. As part of the Hemlock Removal Experiment at the Simes Tract, we annually monitor ant species composition and abundance.

Definition:

Row identifier

An identifier for the set of information associated with an Event (something that occurs at a place and time). May be a global unique identifier or an identifier specific to the data set.

The name identifying the data set from which the record was derived.

The name of, reference to, or description of the method or protocol used during an Event.

The date-time or interval during which an Event occurred. For occurrences, this is the date-time when the event was recorded. Not suitable for a time in a geological context.

The geographic latitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are north of the Equator, negative values are south of it. Legal values lie between -90 and 90, inclusive.

The geographic longitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are east of the Greenwich Meridian, negative values are west of it. Legal values lie between -180 and 180, inclusive.

Notes or comments about the spatial description determination, explaining assumptions made in addition or opposition to the those formalized in the method referred to in georeferenceProtocol.

Definition:

Row identifier

An identifier for the set of information associated with an Event (something that occurs at a place and time). May be a global unique identifier or an identifier specific to the data set.

An identifier for the Occurrence (as opposed to a particular digital record of the occurrence). In the absence of a persistent global unique identifier, construct one from a combination of identifiers in the record that will most closely make the occurrenceID globally unique.

The specific nature of the data record.

The full scientific name, with authorship and date information if known. When forming part of an Identification, this should be the name in lowest level taxonomic rank that can be determined. This term should not contain identification qualifications, which should instead be supplied in the IdentificationQualifier term.

An identifier for the set of taxon information (data associated with the Taxon class). May be a global unique identifier or an identifier specific to the data set.

The reference to the source in which the specific taxon concept circumscription is defined or implied - traditionally signified by the Latin sensu or sec. (from secundum, meaning according to). For taxa that result from identifications, a reference to the keys, monographs, experts and other sources should be given.

An identifier for the nomenclatural (not taxonomic) details of a scientific name.

Methods and protocols used in the collection of this data package

Description:

This data package is a child (Level 2) of the parent data package (Level 1) listed in the dataSource element below. This Level 2 data package was created using the convert_to_dwca() function of the ecocomDP R library: https://github.com/EDIorg/ecocomDP. Methods of the Level 0 (original source dataset) are included for context:

Description:

A permanent 10 x 10-m grid with 25 equally-spaced sample stations was established near the center of each of the 8 plots in the Hemlock Removal Experiment. Pitfall traps (200-ml cups) are buried flush with the soil surface at each point and capped. Caps are removed for sampling - in June, July, and August in 2003-2005; July and August in 2006; and July only since 2007 - 10 ml of soapy water placed in each cup, and cups left open for 48 hours in dry weather. Trap contents are removed and caps replaced after 48 hours. After pitfall trapping is complete, baits (30 g of crumbled Pecan Sandies cookies on white index cards) are placed at the 25 points and allowed to accumulate ants for 1 hour. Representative individuals are collected from each bait station. Three 3-L litter samples are collected from random locations in the large plots, outside of the sample grid, and sifted in the field. Any ants found in the sifted litter are collected. Plots are walked haphazardly for 1 person-hour and additional foraging ants encountered are collected.
