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

Entomologia 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

EPPO 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

Insect 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 ...

Ariadnema polymorpha gen. et sp. nov. (Scytonemataceae, Cyanobacteria): A new heterocytous cyanobacterium with true and false branching from ruins in the Brazilian Atlantic Forest

Journal of Phycology, EarlyView.
Abstract A novel heterocytous Cyanobacterium, Ariadnema polymorpha gen. et sp. nov., was observed in the northern Brazilian Atlantic Forest (BAF), a globally significant biodiversity hotspot that has microbiome diversity yet to be explored. Isolated from ancient sugarcane mill ruins within the BAF, the new genus (strain CCAPE130) exhibits a unique ...

Crawling under the radar: Two novel Paulinella species expand knowledge about the ecology and evolution of a primary plastid‐containing amoeba lineage

Journal of Phycology, EarlyView.
Abstract The genus Paulinella represents a rare, independent case of primary endosymbiosis, providing a unique system to study the early stages of organelle evolution. Here, we expand current understanding of primary plastid endosymbiosis through the discovery and characterization of two novel photosynthetic amoebae, Paulinella marae sp. nov.

Generating Masks for Image Segmentation in Digitized Herbarium Specimens

, 2019
Digitized herbarium images contain complex information unrelated to the shape and color of the specimens represented within them. This information can contribute a substantial amount of noise if one is to use the image as a proxy for pattern, shape, or ...

Circumscription of three new taxa of Merismopedia‐like Cyanobacteria shows how far convergent evolution can go

Journal of Phycology, EarlyView.
Abstract The genus Merismopedia (Merismopediaceae, Chroococcales), characterized by rectangular colonies with cells arranged in regular perpendicular rows and columns, represents a challenging study system due to its limited cultivability. The genus recently underwent taxonomic revision using cultivation‐independent techniques and a polyphasic approach.

Fletcheria gen. nov. (Ralfsiales, Phaeophyceae): A new crustose brown algal genus clarifying evolutionary relationships of Ralfsia pacifica

Journal of Phycology, EarlyView.
Abstract The genus Ralfsia was historically broadly circumscribed but has recently undergone significant taxonomic revision. Based on molecular data, a restricted Ralfsia sensu stricto was delineated that had many species reassigned to new genera and families.
