Using Data From Index Herbariorum to Assess Threats to the World's Herbaria

open access: yes, 2018
During the past few years, natural disasters, political or social unrest and institutional actions have imperiled herbaria. The question has been raised multiple times whether or not the data gathered about herbaria in Index Herbariorum could be used to ...

HGTScanner: Detecting horizontal gene transfer at the fine scale using whole organelle genomes

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Horizontal gene transfer (HGT) has profoundly shaped eukaryotic organellar genomes like plant mitochondria. Yet no generalized tools are currently available to efficiently characterize HGT across these genomes due to both high structural complexity and low sequence divergence compared to prokaryotic HGTs.

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

open access: yesBoreas, EarlyView.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

Evolutionary framework and tribal circumscription of Amaranthaceae sensu stricto based on a comprehensive phylogenomic analysis

open access: yesCladistics, EarlyView.
Abstract The evolutionary history of Amaranthaceae sensu stricto (s.s.) has been shaped by multiple whole‐genome duplications and rapid radiations, producing an ecologically diverse lineage whose internal relationships have long remained unresolved.

Leveraging obligate mutualism to resolve the rare species modeling paradox

open access: yesConservation Science and Practice, EarlyView.
Species distribution models (SDMs) have emerged as vital tools for devising biodiversity conservation planning, yet modeling rare, data‐deficient species remains a significant challenge. To address this “rare species modelling paradox,” we propose a novel approach which posits that under the condition of significant niche overlap between the obligate ...

Accessing Information about Plants in the Region’s Herbaria

open access: yes, 2012
Herbaria are working together to providing online access to the information in their collections. The process involves databasing label and annotation data from individual specimens, georeferencing the collection locations, and (often) imaging the ...

Similar or Different? Configurations of Authenticity Across Museum Types

open access: yesCurator: The Museum Journal, EarlyView.
ABSTRACT Authenticity is traditionally regarded as playing a crucial role in museums, science centers, and memorials. However, despite this fact, authenticity has very different meanings in different (institutional) settings. This complicates shared communications across museum practices.

Biology of the Gall Midge Spanolepis selloanae (Diptera, Cecidomyiidae), a Candidate Biological Control Agent of the Invasive Grass Cortaderia selloana

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Spanolepis selloanae (Diptera, Cecidomyiidae) infests Cortaderia selloana (pampas grass). It lays eggs in the spikelets, where larvae feed on female parts. The high prevalence of the midge and its combined impact in seed production, condition and viability strongly reduces the reproductive output of C. selloana.

Broussonetia papyrifera (L.) L’Hér. ex Vent., Microstegium vimineum (Trin.) A.Camus and Parthenium hysterophorus L. imported into the Netherlands via potted ornamentals or their coco peat substrate

open access: yesEPPO Bulletin, EarlyView.
Abstract While the presence of invasive plants as contaminants in potted plants is a well‐known phenomenon, its significance as a potential phytosanitary risk remains frequently underestimated. Coco peat, often used as a growing medium for potted plants, is also imported as a standalone commodity, creating an additional pathway for introduction.

Species diversity and host plant associations of ambrosia beetles in Southeast Asian forests of Laos and Vietnam revealed by DNA barcoding

open access: yesInsect Conservation and Diversity, EarlyView.
Integrative DNA barcoding of ambrosia beetles and host plants revealed 27 beetle species across 16 genera and extensive, previously undocumented host plant diversity in Laos and Vietnam. Host specificity varied widely among ambrosia beetles, with Xylosandrus crassiusculus emerging as a dominant generalist associated with 19 host species from 12 plant ...
