A unique Early Iron Age brooch from Somló Hill

open access: yesCommunicationes Archaeologicae Hungariae
The aim of this paper is to present an important addition to our knowledge about the Early Iron Age of Somló Hill. In early February 2023, during a metal detector survey of the hill volunteer detectorist Roland Moklovsky found a bronze brooch decorated ...

A case of budding speciation in the California Floristic Province and infraspecific divergence in Abronia villosa

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Budding speciation occurs when peripheral populations adapt to local ecological conditions and “bud” off from a widespread progenitor species. Traditionally regarded as rare because of its sympatric and parapatric nature, budding speciation is largely understudied.

Adult male bagworm moths from Ukrainian and Baltic Eocene amber (Psychidae, Lepidoptera) [PDF]

open access: yesZitteliana
Psychid moths from Ukrainian and Baltic amber are described for the first time by male adults. Recognition was possible by their pectinate antennae and reduced mouthparts at first.

Expanded application to plant reproductive tissues of a branched DNA probe‐based in situ hybridization method

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Detecting clear tissue‐ and organ‐specific patterns of gene expression is key to understanding the genetic mechanisms that control plant development. In situ hybridization (ISH) of mRNA is one of the most precise, yet most challenging approaches to gene expression assays.

Enabling the study of gene function in gymnosperms: Virus‐induced gene silencing in Ephedra tweedieana

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the

Turning a new leaf: PhenoVision provides leaf phenology data at the global scale

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Plant phenology dictates many aspects of community function and ecosystem dynamics. Yet, global phenology data are still limited, especially in areas lacking monitoring programs. Here we present a new data resource, PhenoVision–Leaf, which extends a computer vision pipeline utilizing iNaturalist digital image vouchers to produce global‐

Museum libraries: how digitization can enhance the value of the museum [PDF]

open access: yes, 2011
It is the responsibility of the museum library to enhance the understanding of the museum collection and the role of museum objects as cultural documents. For many reasons, this role is only partially fulfilled, if at all. This is because in practice the

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

open access: yesThe Anatomical Record, EarlyView.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...
