Title:Ant Assemblages in Hemlock Removal Experiment at Harvard Forest since 2003 (Reformatted to a Darwin Core Archive)
Alternate Identifier:DOI PLACE HOLDER
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.lternet.edu/package/metadata/eml/edi/193/3, which was derived from the Level 0 data package found here: https://pasta.lternet.edu/package/metadata/eml/knb-lter-hfr/118/30. 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.

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 L1_to_L2_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.
