Image‐based taxonomic classification of bulk insect biodiversity samples using deep learning and domain adaptation

open access: yesSystematic Entomology, Volume 48, Issue 3, Page 387-401, July 2023., 2023
We evaluated deep learning models for image classification under a realistic setting of biodiversity surveys, where models trained with global image sources predict samples from an unstudied target area. The accuracy of between‐datasets predictions (across disparate source–target pairs that do not share any species) was 82% and depended greatly on the ...

Modelling pollinator and nonpollinator selection on flower colour variation

open access: yesJournal of Ecology, Volume 111, Issue 4, Page 746-760, April 2023., 2023
Understanding the driving forces for evolution of flower colour variation is a central topic in floral biology. This paper uses a modelling approach to evaluate the role of pigmentation on this diversity assuming pigments can be jointly expressed in vegetative and flower tissue. In flowers, pigments influence flower attractiveness to pollinators, while

Multimodal floral cues resembling both generalized food sources and oviposition sites in Isotrema manshuriense (Aristolochiaceae) pollinated by flies. [PDF]

open access: yesPlant Biol (Stuttg)
The protogynous flowers of Isotrema manshuriense exhibit multimodal cues, resembling both generalized food sources and fly oviposition sites, with these cues varying across sexual phases. Abstract The genus Aristolochia is renowned for its kettle‐like trap flowers that temporarily retain visiting insects, primarily using trapping trichomes.

Changes in the Carpathian fauna of Malachiinae beetles (Coleoptera, Melyridae) in the context of temperature increase

open access: yesBiosystems Diversity, 2023
Over last century in Europe a tendency of change in species ranges has occurred for insects of different taxonomic groups. We analyzed the changes that have taken place in the distribution of some soft-winged beetles (Malachiinae, Melyridae) species in ...

Comparative morphology of the endophallic structures of the genus Laius (Coleoptera, Melyridae), with the descriptions of three new species

open access: yesEuropean Journal of Taxonomy, 2014
The endophallic structure of the genus Laius is studied and discussed based on the examination of 19 species from Asia to the Indian Ocean. The structure contains two primary sclerites (named gonoporal piece and ligula), a secondary sclerite on the basal
