Data Records

The data in this occurrence 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 58 records.

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.

Geographic Coverage

The data collected is situated on the largest island of Fiji, Viti Levu under the provinces of Navosa (17.9865° S, 177.6581° E) and Namosi (18.0864° S, 178.1291° E).

Taxonomic Coverage

Fijian endemic cicada that emerges once every eight years. Species Raiateana knowlesi (Fijian cicada), "nanai" as natively known in Fiji.

Temporal Coverage

Project Data

Previously recorded from the village of Matokana in the Navosa Province and then in the Garrick Forest reserve in Namosi in 2009, the emergence showed the distribution of the Fijian Cicada.

Sampling Methods

-Record the Call of the Nanai: Use the Bug Bag 1. Place bag over an emerging Nanai 2. Capture adult 3. Take to a quiet place and record the call -Sample of Nanai 1. Recently crawled out nymph 2. Recently abandoned shell 3. Emerging adult 4. Recently emerged adult 5. Full adult - Note the Habitat and vegetation type as well as its time and date of emergence,mating, eggs hatching, when the Nanai started crawling out of the ground, when they started singing and when they died.

Method step description:

1. Directions for Digging •Find locations where last emergence was most dense •Check branches of trees for egg scars •If you find egg scars, start digging below that area/branch •Identify the tree species at which you found egg scars • Cut through squares of Earth with the blade of the shovel and carefully pull up the soil nymphs can be found within 30cm of the surface, but they can be found deeper. Directions to set up plot i.Create square meter plots under the trees with egg nests ii.Label with a permanent label and stake at each corner iii.Enrich these plots with hatching Cicada from an adjacent area iv.Count the number of egg nests. Place a quantity of twigs in a pile inside each plot. The eggs will hatch, nymphs will jump out of the branches and crawl into the ground. v.Create replicate plots with different densities of nymphs. vi.Sample nymphs once or twice a year using a standard protocol. vii.Compare nymphal growth rates under different density conditions. Alternatively, all plots can be supplemented with the same densities of nymphs, increasing the density of egg nests in a plot will increase the probability of finding nymphs in that plot in later years.
