The purpose of the present study was to evaluate and assess the capability of Zataria multiflora, Geranium herbarium, and Eucalyptus camaldolensis essential oils in treating Saprolegnia parasitica-infected rainbow (Oncorhynchus mykiss) trout eggs. A total of 150 infected eggs were collected and plated on glucose-pepton agar at 24°C for 2 weeks. The antifungal assay of essential oils against S. ...

The application of DNA sequencing technology to the study of ancient DNA has enabled the reconstruction of past epidemics from genomes of historically important plant-associated microbes. Recently, the genome sequences of the potato late blight pathogen Phytophthora infestans were analyzed from 19th century herbarium specimens. These herbarium samples originated from infected potatoes collected...

Herbarium specimens are a vital resource in botanical taxonomy. Many herbaria are undertaking large-scale digitization projects to improve access and to preserve delicate specimens, and in doing so are creating large sets of images. Leaf characters are important for describing taxa and distinguishing between them and they can be measured from herbarium specimens. Here, we demonstrate that herba...

PREMISE OF THE STUDY Climate change has resulted in major changes in the phenology of some species but not others. Long-term field observational records provide the best assessment of these changes, but geographic and taxonomic biases limit their utility. Plant specimens in herbaria have been hypothesized to provide a wealth of additional data for studying phenological responses to climatic cha...

Heteroconium schimae sp. nov. is described and illustrated occurring on dead branches of Schima superba. The specimen was collected from tropical forests in Fujian province of China. The type specimen is deposited in HSAUP (Herbarium of the Department of Plant Pathology, Shandong Agricultural University) and HMAS (Mycological Herbarium, Institute of Microbiology, Chinese Academy of Sciences).

This contribution introduces the ongoing research on herbaceous bamboos started by the University of Florence (FT herbarium), the Universidad de Panama (PMA herbarium) and the Smithsonian Tropical Research Institute in 2011. The main goal of this project consists in collecting field data, in order to provide updated material to be used in a phylogenetic analysis to improve the knowledge of the ...

A method is described to construct magnetic fumicel packets for holding solid insect repellants (e.g., naphthalene and paradichlorobenzene) used in the herbarium. the fumicels are designed to attach magnetically to metal herbarium cabinets. they are made entirely of archival materials, and are inexpensive and easily assembled.
