Preliminary assessment of cavity‐nesting Hymenopterans in a low‐intensity agricultural landscape in Transylvania [PDF]

open access: yesEcology and Evolution, 2021
In this study, our aim was to assess several traits of cavity‐nesting Hymenopteran taxa in a low‐intensity agricultural landscape in Transylvania. The study took place between May and August 2018 at eight study sites in the hilly mountainous central part

The role of wild bees and cavity‐nesting wasps as ecological indicators of the last traditionally managed meadows in Eastern Europe [PDF]

open access: yesEcology and Evolution
The number of wild bees and cavity‐nesting wasps is abundant in agricultural areas and they contribute significantly to ecosystem services. Due to their specialization in nesting sites and food sources, these groups are sensitive to habitat condition ...

No evidence for environmental filtering of cavity‐nesting solitary bees and wasps by urbanization using trap nests [PDF]

open access: yesEcology and Evolution, 2022
Spatial patterns in biodiversity are used to establish conservation priorities and ecosystem management plans. The environmental filtering of communities along urbanization gradients has been used to explain biodiversity patterns but demonstrating ...

On the systematics of Trypoxylon scrobiferum Richards and T. anapaike Amarante with the recognition of a new species group in the subgenus Trypoxylon (Hymenoptera: Crabronidae: Trypoxylini)

open access: yesPapeis Avulsos De Zoologia, 2005
The males of Trypoxylon scrobiferum Richards and T. anapaike Amarante are described for the first time and their genitalia illustrated. These species are demonstrated to represent a monophyletic group, and the scrobiferum species group is established for

Molecular characterization of constitutive heterochromatin in three species of Trypoxylon (Hymenoptera, Crabronidae, Trypoxylini) by CMA3/DAPI staining [PDF]

open access: yesComparative Cytogenetics, 2011
Previous cytogenetic analyses in Trypoxylon Latreille, 1796 have been basically restricted to C-banding. In the present study, base-specific CMA3 and DAPI fluorochrome staining were used to characterize the constitutive heterochromatin in three ...
