Competition from Below for Light and Nutrients Shifts Productivity Among Tropical Species
Competition from below for light and nutrients shifts productivity among tropical species John J. Ewela,1 and Mari´a Julia Mazzarinob aDepartment of Biology, University of Florida, Gainesville, FL 32611; and bConsejo Nacional de Investigaciones Científicas y Te´cnicas de Argentina, Universidad Nacional del Comahue, 8400 Bariloche, Argentina Edited by Christopher B. Field, Carnegie Institution of Washington, Stanford, CA, and approved October 3, 2008 (received for review July 24, 2008) Chance events such as seed dispersal determine the potential canopy: Hyeronima alchorneoides, Cedrela odorata, and Cordia composition of plant communities, but the eventual assemblage is alliodora; 1 alien palm, Euterpe oleracea, which has a native determined in large part by subsequent interactions among spe- congener; and 1 native, giant perennial herb, Heliconia imbricata cies. Postcolonization sorting also affects the ultimate composition (all species are referred to hereafter by genus). The intent was of communities assembled by people for restoration, horticulture, to encompass some of the variability within the broad category or conservation. Thus, knowledge of the mechanisms controlling of canopy-tree life form while holding the identity of the interspecific interactions in plant communities is important for monocots (palm and herb) constant. Among other differences, explaining patterns observed in nature and predicting success or Hyeronima (like the 2 monocots) is never leafless whereas the failure of utilitarian combinations. Relationships among species, other 2 tree species are deciduous after attaining age 5–7 yr, especially those from studies of biological diversity and ecosystem Cedrela in the dry season and Cordia in the wet season.

Chris Pires Dr. Lori Eggert Dr. Candace Galen Dr. Rose‐Marie Muzika ACKNOWLEDGEMENTS I am indebted to many people for their assistance during the course of my graduate education. I would not have derived such a keen understanding of the learning process without the tutelage of Dr. Sandi Abell. Members of the Pires lab provided prolific support in improving lab techniques, computational analysis, greenhouse maintenance, and writing support. Team Monocot, including Dr. Mike Kinney, Dr. Roxi Steele, and Erica Wheeler were particularly helpful, but other lab members working on Brassicaceae (Dr. Zhiyong Xiong, Dr. Maqsood Rehman, Pat Edger, Tatiana Arias, Dustin Mayfield) all provided vital support as well. I am also grateful for the support of a high school student, Cady Anderson, and an undergraduate, Tori Docktor, for their assistance in laboratory procedures. Many people, scientist and otherwise, helped with field collections: Dr. Travis Columbus, Hester Bell, Doug and Judy McGoon, Julie Ketner, Katy Klymus, and William Alexander. Many thanks to Barb Sonderman for taking care of my greenhouse collection of many odd plants brought back from the field. -

Antioxidant System Is Insufficient to Prevent Cell Damages in Euterpe Oleracea Exposed to Water Deficit
Emirates Journal of Food and Agriculture. 2017. 29(3): 206-211 doi: 10.9755/ejfa.2016-09-1217 http://www.ejfa.me/ REGULAR ARTICLE Antioxidant system is insufficient to prevent cell damages in Euterpe oleracea exposed to water deficit Maria Antonia Machado Barbosa1, Allan Klynger da Silva Lobato1*, Thaís Soares Pereira1, Gélia Dinah Monteiro Viana1, José Ricardo Santos Barbosa1, Kelly Nayara Nascimento Coelho1 1Núcleo de Pesquisa Vegetal Básica e Aplicada, Universidade Federal Rural da Amazônia. Paragominas, Pará, Brazil ABSTRACT This study aimed to determine whether antioxidant enzymes are efficient to control the oxidative stress and consequent cell damages on leaves and roots in Euterpe oleracea plants exposed to water deficiency. This study was assembled under an experimental design completely randomized with two water conditions (water deficit and control) combined by four evaluation dates (0, 6, 12, and 18 days). Progressive water deficit promoted significant increases in electrolyte leakage and glutathione in both tissue types, and hydrogen peroxide and malondialdehyde were increased in the leaf. Antioxidant enzyme activities showed similar behaviours, with initial increases and subsequent decreases. Our results revealed that the cell damage observed in leaves and roots was induced by multiple effects related to overproduction of oxidant compounds, such as hydrogen peroxide, and by insufficient CAT, APX, and GPX activities in E. oleracea plants exposed to progressive water deficit.

Barnard University of California, Berkeley, USA Abstract This article presents an ethnographic study of ‘freegans’, individuals who use behaviors like dumpster diving for discarded food and voluntary unemployment to protest against environmental degradation and capitalism. While freegans often present their ideology as a totalizing lifestyle which impacts all aspects of their lives, in practice, freegans emphasize what would seem to be the most repellant aspect of their movement: eating wasted food. New Social Movement (NSM) theory would suggest that behaviors like dumpster diving are intended to assert difference and an alternative identity, rather than make more traditional social movement claims. -
Political Process, Activism, and Health Dissertation
POLITICAL PROCESS, ACTIVISM, AND HEALTH DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Anne E. Haas, M.A. ***** The Ohio State University 2005 Dissertation Committee: Approved by Professor Vincent Roscigno, Advisor Professor Timothy Curry ________________________ Professor Steven Lopez Sociology Graduate Program ABSTRACT Conventional women are saturated with mass media images depicting very thin, attractive women. These images impose ideals that are impossible for most women to meet in a healthy way. This study examines the substantive issue of women's body appearance, aging, and related health outcomes, including eating disorders, and how these might be mediated and improved by activist political process. Concepts from social movements and social-psychological perspectives are integrated into what I call the political process model—a model that delineates how activists become socialized and immersed in alternative political networks that influence subsequent activities, ideas, and identities. I use this model to test the ability of activists to sustain commitment to their causes, including those that relate to women’s bodies, over time. The process that connects the concepts in this model (i.e., pivotal events, collective identity, pivotal departures, empowerment, and health) provides the conceptual framework to which my analytic strategy derives. I address four research expectations using triangulated quantitative and qualitative methods, and draw original data sources. Original survey data on female activists and non-activists are used to test whether the two groups differ in their politics, daily routines, and several dimensions of health (e.g., use of conventional versus non-conventional medical care, eating habits, etc.). -

However, only a few species have significant economic potential. These palms occur essentiallyin seasonal swamp forests on waterlogged soils covering vast areas in Peruvian Amazonia, or on sandy soils. Three especially promising species- Jessenia bataua, Mauritia flexuosa and Euterpe pre- catoria-constitute dense populations on these soils, which are generally considered as unfit for agriculture. The management of promising palm populations will contribute to increasing -

(EO), popularly known as açaí, belongs to the Arecaceae family and grows abundantly in Brazil. The fruit of this palm tree is widely used because of its anti-inflammatory and antioxidant properties. In this review, a search for literature and patent technological prospecting has been performed on the use of EO to treat and prevent diseases as well as to prepare pharmaceutical formulations. EO leaves, fruits, and oil stand out for their large number of pharmacological activities such as anti-inflammatory, antioxidant, antimicrobial, antinociceptive, anticancer, anti-atherogenic, and healing activities, protection against metabolic syndromes such as diabetes, hypertension, and hyperlipidemia, and protection of organs such as lung, kidney, liver, heart, and nervous system. While the phytochemical composition is intrinsically linked to identified biological activities, discoveries of the past decade concerning the use of this species have shown pharmacological alternatives mainly in the treatment and prevention of breast cancer and metabolic syndromes. -
