Metabarcoding of trap nests reveals differential impact of urbanization on cavity‐nesting bee and wasp communities

open access: yesMolecular Ecology, Volume 32, Issue 23, Page 6449-6460, December 2023., 2023
Abstract Urbanization is affecting arthropod communities worldwide, for example by changing the availability of food resources. However, the strength and direction of a community's response is species‐specific and depends on species' trophic level. Here, we investigated interacting species at different trophic levels in nests of cavity‐nesting bees and

Assessing the Proteomic Activity of the Venom of the Ant Ectatomma tuberculatum (Hymenoptera: Formicidae: Ectatomminae)

open access: yesPsyche: A Journal of Entomology, Volume 2018, Issue 1, 2018., 2018
Ectatomma tuberculatum has one of the most toxic venoms known among ants but there is no detailed study on its characteristics. In light of this, knowing the venom’s chemical composition is of paramount importance in order to obtain information about the mechanisms of its components.

Species Composition and Visiting Frequencies of Flower Visitors of Chromolaena odorata in a Dry Zone Forest Patch of Sri Lanka

open access: yesPsyche: A Journal of Entomology, Volume 2016, Issue 1, 2016., 2016
Plant‐animal interaction has been a major theme in ecology as it has helped ecologists to rule out different patterns they observed in the surrounding environments. Chromolaena odorata is another plant species that is studied extensively as it has become a major troublesome weed in many parts of the tropics.

open access: yesPsyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
Pollination biology of the invasive plant sulfur cinquefoil (Potentilla recta L.) and it′s native cooccurring congener slender cinquefoil (P. gracilis Dougl. ex. Hook.) was studied from 2002–2004, at four sites in northeastern Oregon, USA The native cinquefoil flowered first for five weeks, followed by the invasive for five weeks, with two weeks ...

The Nest of Zethus otomitus (Hymenoptera: Eumenidae)

open access: yesThe Florida Entomologist, 1977
This is the first description and illustration of the nest of Zethus otomitus Saussure. Four nests were observed in a fallen log at Cola de Caballo in Nuevo Leon, Mexico. Several other nesting sites were seen in the same area. The nest suggests an intermediate nesting behavior between species utilizing abandoned insect burrows and the subsocial ...

When Bigger Is not Better: Corolla Length Increases Nectar Robbing in Aloe secundiflora Engl. (Asphodelaceae)

open access: yesAfrican Journal of Ecology, Volume 64, Issue 7, October 2026.
ABSTRACT Nectar robbing is a widespread but unevenly documented component of plant–pollinator interactions, and quantitative assessments from African savanna systems remain limited. Based on a short field survey conducted over two consecutive days, this study quantified the frequency and reproductive consequences of nectar robbing in a population of ...
