Transgressive Little Pests: Hiker Descriptions of “Shelter Mice” on the Appalachian Trail

Running between Springer Mountain in the state of Georgia, and Mount Katahdin in Maine, the Appalachian Trail (AT) is a more than 2,000 mile long “wilderness” corridor in the United States. People aiming to undertake a trek of the entire length of the trail can expect to spend approximately six months of their lives on it, sleeping outdoors or in the rudimentary, three-sided shelters that are dotted along it. This paper looks at hiker narratives that described unpleasant encounters between themselves and the mice (Mus musculus and Peromyscus maniculatus) who inhabit these shelters. Many people who attempt to hike the entire length of the AT also choose to blog about their experiences on the trail, thereby creating a parallel community online of AT “thru hikers” as they are known. The data for this study were retrieved from blogs posted by AT thru hikers over the years 2015 and 2016. The most common response to shelter mice was one expressing deep discomfort. This paper asks what it was like to live in close proximity to a species that people usually avoid, what about mice meant that they were perceived as distasteful and even disgusting, and how hikers thought about these nonhuman animals and made sense of their encounters with them afterwards. It is found that hiker reactions to shelter mice were informed largely by their perception of them as being transgressive.     

“I Don’t See That as a Medical Problem”: Clinicians’ Attitudes and Responses to Requests for Cosmetic Genital Surgery by Adolescents

Labiaplasty is a form of genital surgery to reduce large or protruding labia minora. Internationally, the rates of this surgery among women and girls is increasing and is viewed as a worrying trend. Currently, the main clinical strategy is to reassure adolescents that they are normal by talking about the variation of labia size and appearance and showing pictures demonstrating the wide range of normal female genital appearance. For the most part, policy documents recommend against labiaplasty in adolescents, claiming that it is medically non-essential surgery. In this paper, we contrast findings from our interviews with clinicians with the existing literature and policy documents and we point out areas needing more thought. This is qualitative research using semi-structured interviews. We set out to find out on what basis clinicians decide how to treat or manage adolescent patients seeking labiaplasty. We interviewed clinicians who are likely to be approached by under-eighteens requesting labiaplasty. We use interpretive content analysis and thematic analysis to analyse the data. Our findings support the emphasis on education and reassurance as the first step for all patients, but other issues that have not figured previously in the literature that would alter clinical strategies for managing patients emerge as well. Key findings are that reassurance does not always work and that the distinction between functional and appearance concerns is not a solid foundation in itself for deciding whether surgery is ethically appropriate. We conclude that the distinction between functional and appearance concerns is not ethically relevant. It is open to different interpretations and is not regarded by all clinicians as the definitive factor in relation to surgery. The focus of clinicians should be on relieving distress whatever the cause. Appearance reasons may sometimes justify surgery but, also, functional reasons may sometimes not be sufficient justification for surgery.     

Studies on the Hypertrophic Disease of Cherry (Genus Prunus), So-called “Witch’s Broom” Caused by Taphrina wiesneri

Metabolites of Taphrina wiesneri (Rath.) Mix. were examined. Brassicasterol, stearic acid, and p-hydroxyphenylacetic acid were isolated in crystalline form. p-Hydroxybenzoic acid and vanillic acid were identified by paper chromatography and UV measurement. Palmitic acid was identified by gas-chromatography. The fungus produced usually these compounds on any one of four kinds of medium used. p-Hydroxyphenylacetic acid promoted germination of rape seeds at the concentration of 20 ppm in water and showed inhibition at 250 ppm.

Phenolic acids and their related compounds in Japanese flowering cherry leaves infected by Taphrina wiesneri were examined. In the acidic and neutral extracts of infected cherry leaves (I), eighteen compounds positive to diazotized sulfanilic acid and two fluorescent compounds were detected by paper chromatography. Of these compounds, coumarin, 3, 4-dihydrocoumarin, melilotic acid, o- and p-coumaric acids, p-hydroxybenzoic melilotic acid, ferulic acid and caffeic acid were identified. Melilotic acid and coumarin were obtained in crystalline form. The amount of melilotic acid in I was higher than that in healthy leaves independent of sample source, although increased with the growth of cherry leaves.     

Ethnomycology Among the Nuaulu of the Moluccas: Putting Berlin’s “General Principles” of Ethnobiological Classification to the Test

Ethnomycology among the Nuaulu of the Moluccas: Putting Berlin’s “General Principles” of Ethnobiological Classification to the Test. Berlin's (Ethnobiological Classification: Principles of Categorization of Plants and Animals in Traditional Societies. Princeton University Press, New Jersey, 1992) universal theories of ethnobiological classification have provided an indispensable common rubric to compare data from diverse sources. This paper examines these principles with respect to the naming of mushrooms by the Nuaulu on the eastern Indonesian island of Seram, a people for whom mushrooms have only marginal significance. Concordance to Berlin’s principles is noted in some respects, but the small proportion of overall mycological diversity that is treated, the lack of consistently labeled intermediate rankings, the conflation between specific and generic levels, and the importance of utilitarian considerations challenge Berlin's hierarchically ranked “general purpose” (i.e., natural) model of folk biological taxonomy. A comparative review of the literature on other, mostly tropical ethnomycological classifications, is also included.     

Parasitism of the “Fuller’s rose weevil” Naupactus cervinus by Microctonus sp. in Argentina

We report the occurrence of an unidentified species of the wasp Microctonus Wesmael (Hymenoptera: Braconidae) parasitizing adults of the Fuller’s rose weevil Naupactus cervinus (Boheman) (Coleoptera: Curculionidae), a widespread pest of economically important crops included in the South American tribe Naupactini. Cytochrome c oxidase subunit I-based phylogenetic analysis indicates that the parasitoid is closely related to Microctonus hyperodae Loan. Their first instar larvae show slight morphological differences with this species. Superparasitism by first instar larvae occurred at low frequency. Some teratocytes were observed. Microctonus sp. and its host were infected with different strains of the reproductive parasite Wolbachia pipientis Hertig (Rickettsiales: Rickettsiaceae), although the bacterial lineage harbored by the wasp coincides with that infecting most parthenogenetic Naupactini. This multipartite association (weevil bearing both Wolbachia and Microctonus, and Microctonus bearing Wolbachia) opens challenging perspectives for future research on biological interactions and biological control.     

Response by H. H. Pattee to Jon Umerez’s Paper: “Where Does Pattee’s “How Does a Molecule Become a Message?” Belong in the History of Biosemiotics?”

Umerez’s analysis made me aware of the fundamental differences in the culture of physics and molecular biology and the culture of semiotics from which the new field of biosemiotics arose. These cultures also view histories differently. Considering the evolutionary span and the many hierarchical levels of organization that their models must cover, models at different levels will require different observables and different meanings for common words, like symbol, interpretation, and language. These models as well as their histories should be viewed as complementary rather than competitive. The relation of genetic language and human language is the central issue. They are separated by 4 billion years and require entirely different models. Nevertheless, these languages have in common a unique unlimited expressive power that allows open-ended evolution and creative thought. Understanding the nature of this expressive power and how it arises remains a basic unsolved problem of biosemiotics.     

Reply to Manger’s Commentary on “A quantitative test of the thermogenesis hypothesis of cetacean brain evolution,using phylogenetic comparative methods”

In his Commentary (Manger PR. 2009. Subglacial cetaceans and other mathematical mysteries: a Commentary on “A quantitative test of the thermogenesis hypothesis of cetacean brain evolution, using phylogenetic comparative methods” by C. Maximino. Mar Fresh Behav Physiol. 42: 359–362) on my paper (Maximino C. 2009. A quantitative test of the thermogenesis hypothesis of cetacean brain evolution, using phylogenetic comparative methods. Mar Freshwater Behav Physiol. 42:1–17), Dr Paul Manger noted four errors in the quantitative analysis of the relationship between cetacean encephalization quotients (EQs) and water temperatures, which I suggested was a test of his thermogenesis hypothesis (Manger PR. 2006 Manger, PR. 2006. An examination of cetacean brain structure with a novel hypothesis correlating thermogenesis to the evolution of a big brain. Biol Rev Camb Philos Soc, 81: 293–338.  [Google Scholar]. An examination of cetacean brain structure with a novel hypothesis correlating thermogenesis to the evolution of a big brain. Biol Rev Camb Philos Soc. 81:293–338). These referred to incorrect raw data on water temperatures for two species, odd use of midpoint temperatures as independent variable, lack of inclusion of data on Mysticeti and the use of a differently derived EQ and midpoints instead of the EQs proposed by Manger and temperature ranges; Dr Manger proposed that these errors invalidate the analysis, with special emphasis in an observation that, since my paper did not address the relationship between EQs and temperature range, it did not actually test the thermogenesis hypothesis. In this Reply, I apologize for the mistakes which were made, and show that re-analysis using all the proposed alterations do not qualitatively or quantitatively alter the final result. I also argue that the relationship between phylogenetically correct EQs and midpoint temperatures is a better test of the thermogenesis hypothesis than the relationship between non-phylogenetic EQs and temperature ranges.
