Differential effects of habitat isolation and landscape composition on wasps, bees, and their enemies [PDF]

open access: yes, 2018
Habitat loss and fragmentation are major threats to biodiversity and ecosystem functioning. Effects of these usually intercorrelated processes on biodiversity have rarely been separated at a landscape scale.

Insect–flower interactions, ecosystem functions, and restoration ecology in the northern Sahel: current knowledge and perspectives

open access: yesBiological Reviews, Volume 100, Issue 2, Page 969-995, April 2025.
ABSTRACT Actions for ecological restoration under the Great Green Wall (GGW) initiative in the northern Sahel have been plant focused, paying scant attention to plant–animal interactions that are essential to ecosystem functioning. Calls to accelerate implementation of the GGW make it timely to develop a more solid conceptual foundation for restoration

Evolving perspectives in Hymenoptera systematics: Bridging fossils and genomes across time

open access: yesSystematic Entomology, Volume 50, Issue 1, Page 1-31, January 2025.
Advances in sequencing and phylogenomic methods reveal unresolved deep phylogenetic nodes with variable age estimates in Hymenoptera, including, for example, Eusymphyta and Proctotrupomorpha. Conflicting morphological and molecular data hinder consensus in Hymenoptera systematics.

A teratological case in antenna of Nysson tridens Gerstäcker, 1867 (Hymenoptera: Crabronidae)

open access: yesActa Biologica Sibirica
A case of asymmetry and hypertrophy on the right antenna in the kleptoparasite wasp Nysson tridens Gerstaecker, 1867 is described from Russia. This is the first antennal teratology in the family Crabronidae (Hymenoptera).

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

open access: yesEcology and Evolution, Volume 14, Issue 10, October 2024.
The role of wild bees and cavity‐nesting Hymenopteran species as indicators was examined, along the unique combination of high nature value and traditional land use habitats. The different taxonomic groups of wild bees and cavity‐nesting Hymenopterans showed differences in their habitat affinities.

Two new synonyms in Oriental Crabronidae (Hymenoptera)

open access: yesJournal of Hymenoptera Research, 2011
Malaygorytes konishii Nemkov, 1999 (now Argogorytes konishii) from Western Malaysia is synonymized with Argogorytes matangensis (Turner, 1914) from Eastern Malaysia. Cerceris bantamensis van der Vecht, 1964 from Java is synonymized with Cerceris ferox F. Smith, 1856 (which also occurs in Sumatra and Malaysia).

Multi‐method approach to assessing the floral‐visiting insect assemblage of rare, ambophilous plant Baccharis vanessae in Southern California

open access: yesEcology and Evolution, Volume 14, Issue 10, October 2024.
In this study, we compare the accuracy of two different methods of monitoring to assess the insect assemblage of Encinitas Baccharis (Baccharis vanessae): focal observations and video recordings from camera traps. The insect vectors identified were as expected given B. vanessae pollination syndrome.

Insights from the first phylogenomic analysis of flat wasps (Hymenoptera, Bethylidae) reveal two new subfamilies

open access: yesCladistics, Volume 40, Issue 5, Page 510-525, October 2024.
Abstract Despite significant advances in alpha level taxonomy in the past few decades, the higher‐level phylogeny of flat wasps (Hymenoptera, Bethylidae) remains poorly explored. Herein we provide the first phylogenomic assessment of the family based on data from ultraconserved elements for 96 species in 61 genera of the family, with material from 29 ...
