Ichneumonid subfamily abundances from 38 datasets collected between 25°S and 81°N

Data from a study of latitudinal diversity gradients in the parasitoid wasp family Ichneumonidae, using subfamily abundance from 38 collections made between 25°S and 81°N. All collections in this study were made using Malaise traps.

Data for most of the collections were found in published papers (see below); data from Alberta was collected by Marla Schwarzfeld in association with the Ecoystem Management Emulating Natural Disturbance (EMEND) project; data from northern Canada was collected by Laura Timms in association with the Northern Biodiversity Program (NBP); data from Peru was collected by Ilari Sääksjärvi.

These data are associated with manuscript in review: Timms, L.L., Schwarzfeld, M., and Sääksjärvi, I.E. Extending understanding of latitudinal patterns in parasitoid wasp diversity.

This dataset has 44 columns and 38 rows of data, where each row is the information associated with one collection.

Column titles:

Collection = Abbreviation for the collection

Location = Geographic location (country, state, or province) where the collection took place

Year(s) = Year(s) during which the collection took place

Acae-Xori = these 28 columns contain the abundances 28 ichneumonid subfamilies; the four letter code title of each column is the first four letters of the subfamily name (except for Ortc = Orthocentrinae and Ortp = Orthopelmatinae)

TOT = the total abundance of all ichneumonids in each collection

Lat = latitude of the collection site (where negative values indicate southern hemisphere)

H1 = northern/southern hemisphere

Long = longitude of the collection site

H2 = eastern/western hemisphere

MAP =  mean annual precipitation at the collection site

LGP.mean = mean length of growing period (LGP) at each collection site, based on data from the FAO (http://www.fao.org/geonetwork/srv/en/main.home), where LGP is calculated based on the number of days with a temperature of at least 5°C and with enough moisture for plant growth. Note that LGP values are usually provided by the FAO in the form of ranges, the values given here are the midpoints of those ranges. Also note, the values for NBP.BKS and NBP.HAZ are equal to the mean number of days above 5°C according to the Environment Canada national climate archives; the FAO's LGP values for these regions were erroneously provided as 0.

TD.tot = total number of Malaise trap days in the collection

Traps = total number of Malaise traps used in the collection

dpt = days per trap; mean number of days each Malaise trap was deployed

dpt.lgp = days per trap divided by length of growing period; a measure of the proportion of the active season trapped

Ind.TD.tot = total number of individuals per trap day for the collection

iabd = abundance of idiobionts in the collection

kabd = abundance of koinobionts in the collection

Related reference(s) = associated literature reference(s) for the collection
