Effectiveness and Biases of Winkler Litter Extraction and Pitfall Trapping for Collecting Ground-Dwelling Ants in Northern Temperate Forests
TLDR
The application of both techniques should be considered if the aims of a study require estimation of community properties, such as relative abundance, and the combination of the two sampling techniques allowed for the collection of ≈90% of the ants expected in the surveyed area. Expand
Ant (Hymenoptera: Formicidae) diversity and community composition along sharp urban forest edges
TLDR
It is suggested that the edge effects are most pronounced within 25 m of the forest edge, which may have implications for the overall conservation of forest-dwelling fauna. Expand
New parasitoids of Saperda populnea (L.) (Col. Cerambycidae) in Bulgaria
TLDR
Four new species for the parasitoid complex of S. populnea in Bulgaria were recorded: Dolichomitus tuberculatus (Geoffroy), Xylophrurus lancifer (Gravenhorst), Gelis ornatulus (Thomson) and Dendrocerus serricornis (Boheman) (Hym., Megaspilidae). Expand
Selective Foraging on Ants by a Terrestrial Polymorphic Salamander
TLDR
The findings suggest selective foraging may be more common among generalist predators than previously considered, and it is proposed striped and unstriped morphs may represent a trophic polymorphism in P. cinereus. Expand

I update the last published list of Ohio ants to include 26 new species records and 38 name changes in species already on the list based on literature records, institutional collections, andExpand
Status of the exotic ant Nylanderia flavipes (Hymenoptera: Formicidae) in northeastern Ohio
TLDR
It is argued that this species’ high local abundance and ability to forage at cooler temperatures may give it a competitive advantage and thereby affect native ants through exploitative competition. Expand
Efficiency of the Winkler method for extracting ants (Hymenoptera: Formicidae) from temperate-forest litter
Winkler litter extraction is a commonly used collecting technique for sampling arthropods from leaf litter in forested areas. We evaluated the efficiency of the Winkler method for extracting antsExpand
Insects reared from stems and branches of goat willow (Salix caprea L.) in Bulgaria
TLDR
Seven xylophagous insect species were established in stems and branches of Salix caprea L. caprea during the period 1998–2003 in Bulgaria and two parasitoids had not previously been reported for the fauna of Bulgaria. Expand
Insect inhabitants of old larval galleries of Saperda populnea (L.) (Coleoptera: Cerambycidae) in Bulgaria
The complex of insect inhabitants of old larval galleries of Saperda populnea (L.) (Coleoptera: Cerambycidae) was studied during the period 2000–2003 in 18 localities in Bulgaria. As a result, 32Expand
DISTRIBUTION AND GEOGRAPHIC LIMITS OF THE ALTERNATIVE CYTOTYPES OF TWO MICROTUS VOLES IN EUROPEAN RUSSIA
TLDR
For the first time, hybrid karyotypes were observed in a local sample, providing evidence of natural hybridization in the arvalis - obscurus contact zone. Expand
