A new feather mite species of the genus Ingrassia (Acariformes: Xolalgidae) from the Jacksnipe Lymnocryptes minimus (Charadriiformes: Scolopacidae) in Faroe Islands Open
A new feather mite species Ingrassia lymnocrypti sp. n. is described from the Jacksnipe, Lymnocryptes minimus (Brünnich), collected in Faroe Islands. The new species is close to I. limnodromi Vasyukova and Mironov, 1986 and readily differs…

A new feather mite species of the genus Temnalges (Acariformes: Psoroptoididae) from coots, Fulica spp. (Gruiformes: Rallidae) Open
A new feather mite species, Temnalges fulicae sp. n. (Psoroptoididae: Pandalurinae), is described from two species of coots, Fulica americana Gmelin, 1789 (type host), in Canada, and F. atra Linnaeus, 1758, in Denmark. The new species is c…

A new species of Rhinonyssidae (Mesostigmata) nasal mite (Ptilonyssus simplex n. sp.) from the Bohemian waxwing in Denmark. Open
A new species of nasal mite, Ptilonyssus simplex n. sp. is described and illustrated based on material from Bohemian waxwing, Bombycilla garrulus (Linnaeus, 1758) (Bombycillidae). The bird host was collected in a residental area in Hirtsha…

Hymenopteran parasitoids reared from European gall midges (Diptera, Cecidomyiidae) Open
We report the results of investigations 2010 through 2023 of hymenopteran parasitoids associated with gall midges in Europe. A total of 242 collections of gall midges were made, from each of which one to several parasitoid species emerged,…

Terrestrial Parasitengona mites (Trombidiformes) of Denmark – new data on parasite-host associations and new country records Open
An updated list of terrestrial Parasitengona mites of Denmark, containing 34 species aggregated in eight families, is presented and compared to existing records from Fennoscandia. Five parasitengone species, Charletonia cardinalis, Leptus …

Simple attributes predict the value of plants as hosts to fungal and arthropod communities Open
Fungal and arthropod consumers constitute the vast majority of global terrestrial biodiversity. Yet, the link from richness and composition of producer (plant) communities to the richness of consumer communities is poorly understood. Funga…

Simple attributes predict the importance of plants as hosts to the richness of fungi and arthropods Open
Consumers constitute the vast majority of global terrestrial biodiversity. Yet, local consumer richness is poorly understood. Plant species richness offers a simple hypothesis to how the diversification of carbon substrates may promote the…

Comparison of Two Chemically-Induced Colitis-Models in Adult Zebrafish, Using Optical Projection Tomography and Novel Transcriptional Markers Open
Crohn’s disease and ulcerative colitis—inflammatory bowel diseases (IBD)—are chronic conditions with an inadequately understood pathogenesis. Employing a set of novel molecular markers in a gene expression assay (qPCR), we have used adult …
