Distribution of 18S rDNA clusters in Central European harvestmen of the suborder Eupnoi (Arachnida: Opiliones)

open access: yesEuropean Journal of Entomology, 2020
rDNA clusters are an important cytogenetic marker for studying karyotype evolution and chromosomal changes. The variability of this cytogenetic characteristic is, however, still almost unknown in the karyotypes of the entire class Arachnida (Arthropoda ...

Response of ground-dwelling harvestman assemblages (Arachnida: Opiliones) to European beech forest canopy cover

open access: yesEuropean Journal of Entomology, 2017
We studied the effects of the overstory canopy cover on ground-dwelling harvestmen communities in European beech forests in the Western Carpathian Mts.

Do sexually dimorphic glands in the harvestman Gryne perlata (Arachnida: Opiliones) release contact pheromones during mating?

open access: yesEuropean Journal of Entomology, 2016
There are records of glands that produce sexual pheromones that are released into the environment or applied directly on sexual partners. Within Opiliones (Arachnida), several harvestmen in the suborder Laniatores have sexually dimorphic glands on legs I

The quality of aphids as food for generalist predators: implications for natural control of aphids

open access: yesEuropean Journal of Entomology, 2005
The paper reviews existing data on the food quality of cereal aphids for generalist predators. Data are presented for spiders, harvestmen, carabid and staphylinid beetles, cockroaches, ants and one species of bird.

Phylogenomic resolution of paleozoic divergences in harvestmen (Arachnida, Opiliones) via analysis of next-generation transcriptome data.

open access: yesPLoS ONE, 2012
Next-generation sequencing technologies are rapidly transforming molecular systematic studies of non-model animal taxa. The arachnid order Opiliones (commonly known as "harvestmen") includes more than 6,400 described species placed into four well ...

Arthropod distribution on an alpine elevational gradient: the relationship with preferred temperature and cold tolerance

open access: yesEuropean Journal of Entomology, 2001
The distribution of arthropod species on a 400 m elevational gradient (equivalent to a temperature decrease of 2.5°C) on Snowdon, North Wales, was examined and compared with the British distribution.

Insufficient Logging Intervals Impede Upper Soil Recovery in Temperate Beech Forests: Insights From Two Case-Studies in Poland. [PDF]

open access: yesEcol Evol
This study examined the effects of forest operations on soil microarthropod biodiversity and litter decomposition in temperate beech forests, comparing disturbed and undisturbed soils across different harvesting timelines. While litter decomposition remained unaffected, significant soil disturbances were found in areas impacted by machine passage, with

A Model for Phylogenetic Chemosystematics: Evolutionary History of Quinones in the Scent Gland Secretions of Harvestmen

open access: yesFrontiers in Ecology and Evolution, 2017
By the possession of unique exocrine scent glands, Opiliones (harvestmen) arise as a perfect model for studies on the evolutionary history of secretion chemistry.

Metabarcoding Reveals the Dietary Patterns of Bats Within a Unique European Habitat, the Pasture-Dominated Landscapes of Ireland. [PDF]

open access: yesEcol Evol
We investigated the diets of two common insectivorous bat species, Plecotus auritus and Pipistrellus pygmaeus, across the pastureland‐dominated landscape of Ireland. Using metabarcoding and next‐generation sequencing, we analysed 4627 faecal samples collected over three years from twelve maternity roosts during gestation, lactation, and post‐lactation ...
