Seed germination, phenology, and antiedematogenic activity of
Background Peperomia pellucida is popularly known as coraçãozinho in the Brazilian northeast and is used in the treatment of abscesses, furuncles, and conjunctivitis. Our work aimed to determine the term of the development stages and the species cycle in the four seasons of the year (complete development, beginning of bloom, complete bloom, and seed set), verifying the plant's therapeutic profile during the four distinct development phases in order to detect differences in its potency. Pharmacological tests were performed to observe the anti-inflammatory activity. Results Phenological observations were accessed for a 12 month-period, from the Brazilian summer of 1999/2000 to fall 2000. On average the plantules' emergence occurred 15 days after seeding. All plantules grew in a similar manner up to 25 days after transplantation in all seasons. Starting on the 25th day, we observed faster growth during spring, with plants reaching a height of about 60 cm after 100 days of transplantation, unlike other seasons, in which plants reached heights of 40, 40, and 35 cm during winter, summer, and fall, respectively. The P. pellucida aqueous extract showed significant anti-inflammatory activity during phenophases 1 and 2 of winter and spring. Depending on the plant's phenophase there was variation in the potency of edema inhibition. Conclusion P. pellucida has a phenological cycle of approximately 100 days. It is recommended that the P. pellucida aqueous extract is used as an antiedematogenic only during phenophases 1 and 2 of winter and spring.

Invasive Plant Inventory and Early Detection Prioritization Tool for Stewart B. McKinney NWR
공공데이터포털
In 2010-2013, the U. S. Fish and Wildlife Service (USFWS) partnered with Utah State University to conduct invasive plant prioritization workshops and inventories on selected National Wildlife Refuges across the United States. The purpose of these workshops and subsequent inventories was to inform and improve the process of planning and implementing invasive plant inventories or early detection. These workshops highlighted the need for an objective, transparent and documented process for deciding which invasive plant species should be a focus of inventory or early detection (and ultimately management) and where. A result of this partnership is the Invasive Plant Inventory and Early Detection Prioritization Tool (IPIEDT) and associated user's guide. The tool is a Microsoft Access database (2010 or later) that utilizes site-specific knowledge and harnesses existing invasive plant information (invasive species risk rankings) to identify priority species and areas for inventory or early detection. The tool produces a ranked list of areas and invasive plant species to consider for inventory or early detection. Once the location and abundance of priority invasive plants are understood, this information can be used to decide what specific management strategies should be employed and where. Interior 1 Regional and Refuge staff used the database developed by Utah State and the Pacific Southwest Region to prioritize invasives species at Stewart B. McKinney. The attached products are the result of that prioritization.
