Automated Detection and Monitoring of Ground‐Nesting Bee Nests Using Drone Imagery and Deep Learning
Ecology and Evolution, Volume 16, Issue 1, January 2026.We demonstrate the feasibility of integrating drone‐based image acquisition with deep learning to accurately detect soil mounds produced by ground‐nesting bees, indicating nest presence, and reliably distinguish them from other soil surface deposits. This approach has the potential to gain new insights into bee nesting biology and population dynamics ...

UAV‐based remote sensing of bee nesting aggregations with computer vision for object detection
Journal of Applied Ecology, Volume 63, Issue 1, January 2026.Our novel application of UAV imagery and object detection models for mapping and censusing ground nesting bee aggregations represents a rapid, cost‐effective solution for overcoming limitations in traditional manual methods. This workflow has applications for bee conservation, management and research such as monitoring bee nesting populations before ...

The Socio‐Political Dimension of Hysteria and Melancholia—Between Revolution and Stagnation
International Journal of Applied Psychoanalytic Studies, Volume 22, Issue 4, December 2025.ABSTRACT This paper explores the psychoanalytic distinction between hysteria and melancholia as mechanisms of trauma processing and their implications for socio‐political dynamics. Through an examination of Freud and Klein, with reference to Lacan, Deleuze and Sartre, this study proposes a regression‐oscillation hypothesis, arguing that subjects move ...

A faunistic study on digger wasps of Iran (Hymenoptera)
Natura Somogyiensis, 2018 Abstract: This paper deals with distribution data of 53 species of Iranian digger wasps from 27 genera and three families, Ampulicidae (single species), Crabronidae (28 species, 16 genera) and Sphecidae (24 species, 9 genera). Eight species are new records for the fauna of Iran: Bembix diversipes F.

Communal Nesting in the Digger Wasp Cerceris australis (Hymenoptera : Sphecidae)
Australian Journal of Zoology, 1982 Study of 39 nests of Cerceris australis at nine localities in eastern Australia has demonstrated that most nests are occupied by two or three successive generations of wasps and may ultimately contain well over 100 cells. Nests are dug deep in the soil and are provisioned with scarab beetles, which are allowed to accumulate in the burrow before from ...

New genus and two new species of the Lower Cretaceous Digger Wasp from Spain (Hymenoptera: Sphecidae: Angarosphecinae) [PDF]
, 2000 One new genus and two new species, Ilerdosphex wenzae RASNITSYN n.gen. and n.sp. and Pompilopterus montsecensis RASNITSYN n.sp., are described in the digger wasp subfamily Angarosphecinae (Sphecidae) from the Lower Cretaceous (possibly Barremian ...

Ecology, Volume 106, Issue 12, December 2025.Abstract Understanding the stable coexistence of species despite resource competition has been a central topic in ecology. Ant communities are particularly enigmatic as various species coexist despite resource overlap. Community ecology theory predicts stable species coexistence when intraspecific competition is stronger than interspecific competition,

Sting microsculpture in the digger wasp Bembix rostrata (Hymenoptera, Crabronidae) [PDF]
Journal of Hymenoptera Research, 2011 The sting microsculpture of the digger wasp Bembix rostrata (Fabricius, 1781) (Hymenoptera, Crabronidae) is studied with the scanning electron microscope (SEM) for the first time. As in many other hymenopterans, the second valvifer of B. rostrata possesses two fields of styloconic sensilla (hair plates) of proprioceptive function.

Functional Ecology, Volume 39, Issue 12, Page 3487-3503, December 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Many broad‐scale studies along spatial and habitat gradients show that organisms' traits can strongly influence community assembly by facilitating dispersal and environmental filtering.

Oocyte size, egg index, and body lipid content in relation to body size in the solitary bee Megachile rotundata [PDF]
, 2014 Females of solitary, nest-provisioning bees have relatively low fecundity, but produce large eggs as part of their overall strategy of investing substantially in each offspring.
