Assessing threats to species at risk using stage‐structured state–space models: mortality trends in skate populations

Ecological Applications (2009)

Douglas P. Swain Ian D. Jonsen James E. Simon Ransom A. Myers

Population models are needed to assess the threats to species at risk and to evaluate alternative management actions. Data to support modeling is limited for many species at risk, and commonly used approaches generally assume stationary vital rates, a questionable assumption given widespread ecosystem change. We describe a modeling approach that can be applied to time series of length composition data to estimate vital rates and test for changes in these rates. Our approach uses stage-structured population models fit within a Bayesian state-space model. This approach simultaneously allows for both process and observation uncertainty, and it facilitates incorporating prior information on population dynamics and on the monitoring process. We apply these models to populations of winter skate (Leucoraja ocellata) that have been designated as "endangered" or "threatened." These models indicate that natural mortality has decreased for juveniles and increased for adults in these populations. The declines observed in these populations had been attributed to unsustainable rates of bycatch in fisheries for other groundfishes; our analyses indicate that increased natural mortality of adults is also an important factor contributing to these declines. Adult natural mortality was positively related to grey seal (Halichoerus grypus) abundance, suggesting the hypothesis that increased adult mortality reflected increased predation by expanding grey seal herds. Population projections indicated that the threatened population would be expected to stabilize at a low level of abundance if all fishery removals were eliminated, but that the endangered population would likely continue to decline even in the absence of fishery removals. We note that time series of size distributions are available for most marine fish populations monitored by research surveys, and we suggest that a similar approach could be used to extract information from these time series in order to estimate mortality rates and changes in these rates.

Volatile Constituents of Muskmelon (Cucumis melo cv. Mission)

HortScience (1996)

Liangli Yu Denys J. Charles Amots Hetzroni James E. Simon

The volatiles of muskmelon ( Cucumis melo L. reticulatis cv. Mission) were sampled by dichloromethane extraction and dynamic headspace methods and analyzed by gas chromatography (GC) and GC–mass spectroscopy (MS). A total of 34 constituents were identified, with esters contributing 8%–92% of the total volatiles. Butyl propionate, ethyl 3-methylpentanoate, hexadecanoic acid, methyl (methylthio)acetate, propyl butyrate, phenylpropyl alcohol, and vanillin, were recovered only by solvent extraction, while hexanal was only detected using dynamic headspace sampling. Methyl butyrate 35.2%, ethyl acetate 17.1%, butyl acetate 11.6%, ethyl propionate 8.3%, and 3-methylbutyl acetate 6.3% were the major constituents by solvent extraction sampling method. Butyl acetate 35.5%, 3-methylbutyl acetate 20.9%, ethyl acetate 7.3%, 2-butyl acetate 5.6%, and hexyl acetate 3.8% were the major constituents recovered by headspace sampling. Fruit tissue was also separated into five layers (exocarp, outer mesocarp, middle mesocarp, inner mesocarp, and seed cavity) and the volatile constituents differed significantly in content and composition by tissue.

Chemical characterization of basil (Ocimum spp.) based on volatile oils

Flavour and Fragrance Journal (2006)

Roberto F. Vieira James E. Simon

Essential oils extracted from basil (Ocimum spp.) by steam distillation are used to flavor foods, oral products, in fragrances and in traditional medicines. The genus Ocimum contains around 30 species native to the tropics and subtropics, with some species naturalized and/or cultivated in temperate areas. Inter- and intraspecific hybridization have created significant confusion in the botanical systematics of the Ocimum genus. The taxonomy of O. basilicum is further complicated by the existence of numerous varieties, cultivars and chemotypes within the species that do not differ significantly in morphology. The composition of volatile oil constituents was used to characterize the diversity among the most economically important Ocimum species. Using principal component analysis on the aromatic volatile oils, the Ocimum accessions could be separated into five groups, which do not correspond to the different species: (1) citral–spathulenol accessions; (2) linalool-rich accessions; (3) methylchavicol-rich accessions; (4) linalool–methylchavicol accessions; and (5) methyl(E)-cinnamate-rich accessions. The fact that the groups of Ocimum species are based on morphological characteristics does not correspond to the groups based on volatile oil constituents. Copyright © 2006 John Wiley & Sons, Ltd.

Building a collaborative, university-based science-in-action video storytelling model that translates science for public engagement and increases scientists' relatability

Frontiers in Communication (2023)

Dena K. Seidel Xenia K. Morin Marissa Staffen Richard D. Ludescher James E. Simon

Collaborating scientists and storytellers successfully built a university-based science-in-action video storytelling model to test the research question: Can university scientists increase their relatability and public engagement through science-in-action video storytelling? Developed over 14 years, this science storytelling model produced more than a dozen high-visibility narratives that translated science to the public and featured scientists, primarily environmental and climate scientists, who are described in audience surveys as relatable people. This collaborative model, based on long-term trusting partnerships between scientists and video storytellers, documented scientists as they conducted their research and together created narratives intended to humanize scientists as authentic people on journeys of discovery. Unlike traditional documentary filmmaking or journalism, the participatory nature of this translational science model involved scientists in the shared making of narratives to ensure the accuracy of the story's science content. Twelve science and research video story products have reached broad audiences through a variety of venues including television and online streaming platforms such as Public Broadcasting Service (PBS), Netflix, PIVOT TV, iTunes, and Kanopy. With a reach of over 180 million potential public audience viewers, we have demonstrated the effectiveness of this model to produce science and environmental narratives that appeal to the public. Results from post-screening surveys with public, high school, and undergraduate audiences showed perceptions of scientists as relatable. Our data includes feedback from undergraduate and high school students who participated in the video storytelling processes and reported increased relatability to both scientists and science. In 2022, we surveyed undergraduate students using a method that differentiated scientists' potential relatable qualities with scientists' passion for their work, and the scientists' motivation to help others, consistently associated with relatability. The value of this model to scientists is offered throughout this paper as two of our authors are biological scientists who were featured in our original science-in-action videos. Additionally, this model provides a time-saving method for scientists to communicate their research. We propose that translational science stories created using this model may provide audiences with opportunities to vicariously experience scientists' day-to-day choices and challenges and thus may evoke audiences' ability to relate to, and trust in, science.

African Indigenous Vegetables Production and Consumption Behavior of Farmers in Zambia: An Econometric Analysis

Technium Social Sciences Journal (2020)

Surendran Arumugam Ramu Govindasamy James E. Simon Emil Van Wyk Kenneth Chali

African indigenous vegetables (AIVs) have recently received wide attention for their contribution toward food and nutrition security. Promoting the production and consumption of AIVs is likely to mitigate food insecurity and alleviate malnutrition in the African region. To document and analyze existing patterns of AIV production in Zambia, farmers were surveyed in person using a structured questionnaire. A total of 300 farmers were selected from Lusaka (50), Katete (50), Chipata (75), Lundazi (75), and Petauke (75). Analysis of the survey results using logit model identified that those who farm less than 10 acres of farming land, were concerned about nutrition quality of AIVs, reported that price of farm produce is fixed by buyers, were registered as a member of any community group or association, received training related to nutrition and health, saved money for unexpected expenses, and were single are more likely than other farmers to produce AIVs for home consumption. Whereas, those who visited the nearest market two times or more, traded agricultural produce through intermediaries, owned a TV, earned an income above 30,000 kwacha and has a University degree are less likely to produce AIVs for home consumption. These results indicate that interventions aimed at increasing AIV production for home consumption should target specific groups of farmers rather than all farmers. This survey also captures the most common AIVs that are grown in these regions in Zambia: Sweet potato leaves, amaranth and orange sweet potato.

In Vitro Propagation of Borage

HortScience (1987)

Jules Janick James E. Simon A. Whipkey

Abstract In vitro shoot proliferation of borage ( Borago officinalis L.) was achieved in a basal medium based on Murashige and Skoog salts supplemented with 17.6 μ m BA (4 mg·liter −1 ) plus 10% (v/v) coconut water. Rooting of in vitro-produced shoots occurred in basal media and increased in response to the addition of IBA. Rooted shoots were transferred successfully to soil. Immature zygotic embryos cultured in 4.5 μ m 2,4-D (1 mg·liter −1 ) plus coconut water (CW) produce asexual embryos directly from the cotyledonary surface and indirectly from callus. Chemical names used: N -(phenylmethyl)-1 H -purin-6-amine (BA); (2,4-dichlorophenoxy)acetic acid (2,4-D); 1 H -indole-3-butanoic acid (IBA).

Quality and Consumer Studies in the USA of African Herbal Teas for the Natural Product Industry Development in Sub-Sahara Africa

ACS symposium series (2009)

H. Rodolfo Juliani Yvonne Koelliker Michael Bucuk Cara Welch Beverly J. Tepper

In Africa, many plant products have been used over the centuries as herbal teas, and as popular local drinks used as refreshing beverages and for their perceived health and medicinal attributes. With the regionalization and globalization of foods, beverages and natural products, the introduction of new drinks such as African teas into other countries and even regions in Africa can provide new herbal teas to a wide range of new consumers. African herbal teas can also be exported outside the continent into Europe, North America and Asia and in doing so have potential to contribute to the economic development of those involved in the collection or production, processing, packaging and distribution of such products. Information on the quality, chemical analysis and health attributes, and consumer response to new products contribute to the commercialization and marketing success of any product. The aim of this study was to assess the quality parameters, proximate analysis of a few selected African herbal teas (Honeybush, Kinkeliba, Lemongrass, Lippia, Rooibos) during three consecutive years (2004 through 2006). This study also sought to conduct a consumer study to evaluate the intensity of color and flavor and liking ratings for four different African teas to an American college-based audience in the USA.
