Toxicity testing with the collembolans Folsomia fimetaria and Folsomia candida and the results of a ringtest

Annex 3

Bibliometric statistics

An impression of the accumulated knowledge available on collembolans was obtained by searching for common collembolan species names in Science Citation Index (ISI Web of Knowledge/Web of Science accessed Jan 2008). Thus, whenever a species name occurred in a title, abstract or keyword of papers it was counted as a citation. To indicate the attention papers on a certain species have received, the average number of citations was included as a “citation rate” (auto-citations excluded).

Species	ISI indexed papers	Citations	Citation rate
F. candida	398	2082	5
Orchesella cincta	109	1025	9
Onychiurus armatus/Protaphorura armata^[1]	85	919	11
F. fimetaria	63	401	6
Parisotoma notabilis and Isotoma notabilis	42	467	11
Proisotoma minuta	38	155	4
Onychiurus arcticus/Megaphorura arctica	37	381	10
Isotoma viridis/anglicana	36	250	7
Sminthurus viridis	36	115	3
Folsomia quadrioculata	27	225	8
Isotomiella minor	20	138	7
Isotomurus palustris / I. prasinus	18	134	7
Sinella curviseta	13	50	4

Paronychiurus kimi²	5	5	1
Onychiurus folsomi / Orthonychiurus folsomi^[2]	2	9	5

Some species is present under more than one name either because the genus name has been changed or because a species complex has been illuminated and a new species name has been given to a member of a species complex.

[1] The similar onychiurid pair Onychiurus fimatus/Protaphorura fimata was mentioned 26 times, and cited 219 times, so the species group are similarly “popular” than O. cincta.

[2] Due to its association with Onychiurinae it should be considered together with the other members of this subfamily, which will make the subfamily Onychiurinae the second most commonly published species group.
