Early Eocene climates were globally warm, with ice-free conditions at both poles. Early 16 Eocene polar landmasses supported extensive forest ecosystems of a primarily temperate biota, 17 but also with abundant thermophilic elements such as crocodilians, and mesothermic taxodioid 18 conifers and angiosperms. The globally warm early Eocene was punctuated by geologically brief 19 hyperthermals such as the Paleocene-Eocene Thermal Maximum (PETM), culminating in the 20 Early Eocene Climatic Optimum (EECO), during which the range of thermophilic plants such as 21 palms extended into the Arctic. Climate models have struggled to reproduce early Eocene Arctic 22 warm winters and high precipitation, with models invoking a variety of mechanisms, from 23 atmospheric CO2 levels that are unsupported by proxy evidence, to the role of an enhanced 24 hydrological cycle to reproduce winters that experienced no direct solar energy input yet remained 25 wet and above freezing. -
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. -

These functions are facilitated by the morphological and anatomical structures of the root, formed by the activity of the root apical meristem (RAM) and consecutive patterning and differentiation of specific tissues with distinct functions. Despite the importance of this plant organ, its evolutionary history is not clear, but fossils suggest that roots evolved at least twice, in the lycophyte (clubmosses and their allies) and in the euphyllophyte (ferns and seed plants) lineages. Both lycophyte and euphyllophyte roots grow indeterminately by the action of an apical meristem, which is protected by a root cap.

Rettig ABSTRACT. The minute, reduced plants of family Lemnaceae have presented a formidable challenge to systematic inves- tigations. The simpli®ed morphology of duckweeds has made it particularly dif®cult to reconcile their interspeci®c relation- ships. A comprehensive phylogenetic analysis of all currently recognized species of Lemnaceae has been carried out using more than 4,700 characters that include data from morphology and anatomy, ¯avonoids, allozymes, and DNA sequences from chloroplast genes (rbcL, matK) and introns (trnK, rpl16). All data are reasonably congruent (I(MF) , 6%) and contributed to strong nodal support in combined analyses. Our combined data yield a single, well-resolved, maximum parsimony tree with 30/36 nodes (83%) supported by bootstrap values that exceed 90%. Subfamily Wolf®oideae is a monophyletic clade with 100% bootstrap support; however, subfamily Lemnoideae represents a paraphyletic grade comprising Landoltia, Lemna,and Spirodela. Combined data analysis con®rms the monophyly of Landoltia, Lemna, Spirodela, Wolf®a,andWolf®ella. -

FDA Has No Questions
Valentina Carpio-Téllez Parabel Ltd. 7898 Headwaters Commerce Street Fellsmere, FL 32948 Re: GRAS Notice No. GRN 000742 Dear Ms. Carpio-Téllez: The Food and Drug Administration (FDA, we) completed our evaluation of GRN 000742. We received Parabel’s notice on November 8, 2017 and filed it on December 19, 2017. Parabel submitted amendments to the notice on February 19, 2018; April 16, 2018; June 12, 2018; and August 1, 2018. The amendments included revisions to the dietary exposure assessment. The subjects of the notice are duckweed powder (DWP) and degreened duckweed powder (DDWP) for use as a source of protein in food at levels ranging from 3-20%.1 The notice informs us of Parabel’s view that this use of DWP and DDWP is GRAS through scientific procedures. Our use of the terms “duckweed powder” and “degreened duckweed powder” in this letter is not our recommendation of those terms as appropriate common or usual names for declaring the substances in accordance with FDA’s labeling requirements. Under Title 21 of the United States Code of Federal Regulations (CFR) 101.4, each ingredient must be declared by its common or usual name. In addition, 21 CFR 102.5 outlines general principles to use when establishing common or usual names for nonstandardized foods. Issues associated with labeling and the common or usual name of a food ingredient are under the purview of the Office of Nutrition and Food Labeling (ONFL) in the Center for Food Safety and Applied Nutrition. The Office of Food Additive Safety (OFAS) did not consult with ONFL regarding the appropriate common or usual name for “duckweed powder” and “degreened duckweed powder.” Duckweeds are aquatic plants in the Lemnoideae subfamily of the plant family Araceae.2 The notifier intends to use multiple species from the genera Landoltia, Lemna, Wolffia, and Wolfiella.3 Although the products may derive from different duckweed species, the 1 Excluding products regulated by the United States Department of Agriculture. -
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. -
Growth Response of Lemna Gibba L. (Duckweed) to Copper and Nickel Phytoaccumulation Effet De L’Accumulation De Cu Et Ni Sur La Croissance De Lemna Gibba L

Khellaf, M. Zerdaoui Laboratory of Environmental Engineering, Faculty of Engineering, Badji Mokhtar University, P.O. Box 12, 23000 Annaba, Algeria (E-mail: [email protected] (N. Khellaf); [email protected] (M. Zerdaoui)) RÉSUMÉ Pour déterminer la tolérance et la capacité de phytoaccumulation du cuivre (Cu) et du nickel (Ni) par une espèce de lentilles d’eau, Lemna gibba L., les plantes sont exposées à différentes concentrations de Cu et Ni (0,1 à 2,0 mg/L) dans une solution de Coïc et Lesaint dilué à 1/4. Le pH est maintenu constant à 6,0 (± 0,1) et le flux de lumière est de 12 h/jour. Le cuivre et le nickel sont tolérés par L. gibba à des concentrations ≤ 0,3 mg/L et ≤ 0,5 mg/L, respectivement. Cependant, la croissance des plantes diminue de 50% (I50) quand le milieu de culture contient 0,45 mg/L de Cu ou 0,75 mg/L de Ni. La plus faible concentration causant une inhibition complète (LCI) est de 0,5 et 1,0 mg/L respectivement en présence de Cu et Ni. Les résultats de l’analyse du métal dans les tissus des plantes révèlent une grande accumulation de Cu et une faible accumulation de Ni dans les tissus végétaux (pour la concentration ne causant aucune inhibition dans la croissance). Une diminution de la concentration de métal dans l’eau est également observée.
