In the past few months Winkie Lennihan and Woody Woodward have been collecting aquatic plants, and providing you with samples which, I gather, you identified (or confirmed their identification). Now I must respond to a new request for an aquatic plant list, so I added Lennihan/W oodward observations to other plants on my previous list which were asterisked as "reported, no vouchers on file". That turned the single-page slide into a 2-page list, enclosed is a copy. I would appreciate it if you could examine this list and let me know of any errors.

  • Comparison of Swamp Forest and Phragmites Australis

    Comparison of Swamp Forest and Phragmites Australis

    COMPARISON OF SWAMP FOREST AND PHRAGMITES AUSTRALIS COMMUNITIES AT MENTOR MARSH, MENTOR, OHIO A Thesis Presented in Partial Fulfillment of the Requirements for The Degree Master of Science in the Graduate School of the Ohio State University By Jenica Poznik, B. S. ***** The Ohio State University 2003 Master's Examination Committee: Approved by Dr. Craig Davis, Advisor Dr. Peter Curtis Dr. Jeffery Reutter School of Natural Resources ABSTRACT Two intermixed plant communities within a single wetland were studied. The plant community of Mentor Marsh changed over a period of years beginning in the late 1950’s from an ash-elm-maple swamp forest to a wetland dominated by Phragmites australis (Cav.) Trin. ex Steudel. Causes cited for the dieback of the forest include salt intrusion from a salt fill near the marsh, influence of nutrient runoff from the upland community, and initially higher water levels in the marsh. The area studied contains a mixture of swamp forest and P. australis-dominated communities. Canopy cover was examined as a factor limiting the dominance of P. australis within the marsh. It was found that canopy openness below 7% posed a limitation to the dominance of P. australis where a continuous tree canopy was present. P. australis was also shown to reduce diversity at sites were it dominated, and canopy openness did not fully explain this reduction in diversity. Canopy cover, disturbance history, and other environmental factors play a role in the community composition and diversity. Possible factors to consider in restoring the marsh are discussed. KEYWORDS: Phragmites australis, invasive species, canopy cover, Mentor Marsh ACKNOWLEDGEMENTS A project like this is only possible in a community, and more people have contributed to me than I can remember.

    A WEED REPORT from the book Weed Control in Natural Areas in the Western United States This WEED REPORT does not constitute a formal recommendation. When using herbicides always read the label, and when in doubt consult your farm advisor or county agent. This WEED REPORT is an excerpt from the book Weed Control in Natural Areas in the Western United States and is available wholesale through the UC Weed Research & Information Center (wric.ucdavis.edu) or retail through the Western Society of Weed Science (wsweedscience.org) or the California Invasive Species Council (cal-ipc.org). Ludwigia spp. Waterprimroses Family: Onagraceae Range: Primarily in the coastal states, Washington, Oregon and California; creeping waterprimrose is also found in Arizona and New Mexico. Habitat: Slow-flowing rivers, lake and reservoir margins, and in the shallow waters of canals and floodplains. Origin: Most species are native to South America. L. peploides ssp. peploides is native to California, Arizona, New Mexico, Ludwigia peploides Texas, and Louisiana; ssp. glabrescens (Kuntze) Raven is native to the central and eastern U.S.; and ssp. montevidensis (Spreng.) Raven is introduced from southern South America. L. peploides is sometimes sold as an aquarium or pond ornamental. Impacts: Dense stands degrade natural communities, reduce water quality and floodwater retention, and prevent effective mosquito control. Plants can develop a tangled mat of stems that can reduce water flow in irrigation channels and drainage ditches. Western states listed as Noxious Weed: L. grandiflora, Washington California Invasive Plant Council (Cal-IPC) Inventory: L. hexapetala, High Invasiveness (Alert); L. peploides, High Invasiveness Waterprimroses are floating to emergent perennials with stems to 10 ft long.

    Use of Duckweed, Lemna Minor, As a Protein Feedstuff in Practical Diets for Common Carp, Cyprinus Carpio, Fry

    Turkish Journal of Fisheries and Aquatic Sciences 4: 105-109 (2004) Use of Duckweed, Lemna minor, as a Protein Feedstuff in Practical Diets for Common Carp, Cyprinus carpio, Fry Erdal Yılmaz1,*, øhsan Akyurt1, Gökhan Günal1 1 Mustafa Kemal University, Faculty of Fisheries and Aquaculture, 31034, Antakya, Hatay, Turkey. * Corresponding Author: Tel.: +90. 326 245 58 45/1315; Fax: +90. 326 245 58 17; Received 09 February 2005 E-mail: [email protected] Accepted 09 June 2005 Abstract The use of dried duckweed, Lemna minor, as a dietary protein source for Cyprinus carpio common carp fry reared in baskets was the topic of investigation in this study. Five diets with similar E:P ratios were fed to common carp fry with an average initial weight of 0.29 g for 90 days. A diet containing 5%, 10%, 15%, or 20% duckweed was substituted for the commercial 32% protein control-group diet, fed in normal rations to common carp. There was no significant difference between the growth performance of fish that were fed diets containing up to 20% duckweed and fish that were fed the control diet (P>0.05), except for the group of fish on the 15% duckweed diet. Also, no significant difference was observed among treatments with respect to feed utilization (P>0.05). While carcass lipid content increased, protein content of the fish fed a diet of 15% duckweed decreased compared to other groups (P<0.05). The results showed that a diet consisting of up to 20% content could be used as a complete replacement for commercial feed in diet formulation for common carp fry.
