The Ovule Number Variation Provides New Insights into Taxa Delimitation in Willows (Salix subgen. Salix; Salicaceae)

Salix babylonica, S. alba and S. fragilis are closely related species characterized by the lanceolate, acuminate and serrulate leaves. The boundaries between them are defined by relatively few diagnostic characters, and their identification is not fully solved. Recent studies have demonstrated that the number of ovules present in the ovaries of the willow flower can assist in the identification of the species. The detailed ovule data, characteristic for flowers of each species, S. babylonica, S. alba and S. fragilis, and variation in the number of ovules per ovary were documented using many representatives of these species from various geographic regions. The data included the minimum and maximum number of ovules per valve and per ovary and the percentages of valves with a specific number of ovules in a catkin. Some intermediate genotypes and clusters with similar ovule indexes were observed. The important character for the identification of S. babylonica was the presence of valves with 1 or 2 ovules in the ovaries; S. fragilis had valves with 3 ovules while S. alba had the greater number (4–12)

Current Impediments for New England DOTs to Transition to Sustainable Roadside Practices for Strengthening Pollinator Habitats and Health

Government agencies whose work impacts the environment have sought more sustainable policy changes that require the use of native plants for revegetation. However, New England DOTs have encountered hurdles in attempts to transition from using cool-season turfgrass to implementing the more complicated management practices required to establish native plant communities. Two of the most significant barriers have been the slow transition to mainly using native plants for revegetation and the lack of genetically appropriate ecotypic native plant material (ENPM) produced in the Northeast. Growers of ENPM have resisted increasing production because they struggle to gauge demand due to substantial communication gaps between local producers and end users. Therefore, we organized focus groups with New England state DOTs, Departments of Environmental Protection, and Fish and Wildlife Services to determine their demand for ENPM and to explore their relationships with producers. We determined that the subcontracting of DOTs hinders their ability to develop relationships with producers because it leaves seed source selection in the hands of third parties. Another impediment was found to be the resistance of some maintenance departments to adopt sustainable management practices, such as reduced mowing. In summary, we determined that DOTs would benefit from establishing more direct relationships with producers to communicate their ENPM needs

Short Communication: IPC Salix Cultivar Database Proof-of-Concept

A variety of Salix L. (Willow) tree and shrub cultivars provide resources for significant commercial markets such as bioenergy, environmental applications, basket manufacturing, and ornamental selections. The International Poplar Commission of the Food and Agriculture Organization (IPC FAO) has maintained the Checklist for Cultivars of Salix L. (Willow) since 2015 and now lists 968 epithet records in a Microsoft Excel spreadsheet format. This Proof-of-Concept (POC) investigates using an SQL database to store existing IPC Salix cultivar information and provide users with a format to compare and submit new Salix cultivar entries. The original IPC data were divided into three separate tables: Epithet, Species, and Family. Then, the data were viewed from three different model perspectives: the original Salix IPC spreadsheet data, the Canadian (PWCC), and the Open4st database. Requirements for this process need to balance database integrity rules with the ease of adding new Salix cultivar entries. An integrated approach from all three models proposed three tables: Epithet, Family, and Pedigree. The Epithet and Family tables also included Species data with a reference to a website link for accepted species names and details. The integrated process provides a more robust method to store and report data, but would require dedicated IT personnel to implement and maintain long-term. A potential use case scenario could involve users submitting their Checklist entries to the Salix administrator for review; the entries are then entered into a test environment by IT resources for final review and promotion to a production online environment. Perhaps the most beneficial outcome of this study is the investigation of various strategies and standards for Epithet and Family recording processes, which may benefit the entire Populus and Salix communities
