scholarly journals Early entanglement of Nova Scotian marine animals in pre-plastic fishing gear or maritime debris: indirect evidence from historic ‘sea serpent’ sightings

Author(s):

Marine environmental historians and ethnobiologists have resorted to imaginative means with which to back-cast the temporal frame of reference in order to assess recent anthropogenic changes. The present study, in support of previous work from around the world, indicates that anecdotal accounts from eyewitnesses of purported sightings of sea serpents provides indirect evidence that marine animals in Nova Scotia have been subjected to anthropocentric pressure for a much longer period than commonly presumed. This involves not only direct fishery exploitation, but also perhaps from being bycatch due to entanglement in deployed gear.Key words: Unidentified marine object, entanglement, fishing gear

SummaryA difference in the prevalence of venous thromboembolism (TE) in major human groups has been described and an uneven distribution of FV Leiden mutation over the world has recently been reported.We investigated FV Leiden mutation in 584 apparently healthy sub#jects mostly from populations different from those previously investi#gated: 170 Europeans (Spanish, Italians), 101 sub-saharan Africans (Fon, Bariba, Berba, Dendi), 115 Asians (Indonesians, Chinese, Tharus), 57 Amerindians (Cayapa), 84 Afroamericans (Rio Cayapa, Viche), and 57 Ethiopians (Amhara, Oromo).The mutation was detected in only 1/115 Asian (Tharu) and in 5/170 Europeans (4 Italians, 1 Spanish).These data confirm that in non-Europeans the prevalence of FV mutation is at least 7 times lower than in Europeans and provide indirect evidence of a low prevalence not only of the FV Leiden gene but also of other genes leading to more severe thrombophilia. Finally, findings from the literature together with those pertaining to this study clearly show a marked heterogeneity among Europeans.

Perceptual input imposes and maintains an egocentric frame of reference, which enables orientation. When blindfolded, people tended to mistake the assumed intrinsic axes of symmetry of their immediate environment (a room) for their own egocentric relation to features of the room. When asked to point to the door and window, known to be at mid-points of facing (or adjacent) walls, they pointed with their arms at 180° (or 90°) angles, irrespective of where they thought they were in the room. People did the same when requested to imagine the situation. They justified their responses (inappropriately) by logical necessity or a structural description of the room rather than (appropriately) by relative location of themselves and the reference points. In eight experiments, we explored the effect on this in perception and imagery of: perceptual input (without perceptibility of the target reference points); imaging oneself versus another person; aids to explicit spatial self-consciousness; order of questions about self-location; and the relation of targets to the axes of symmetry of the room. The results indicate that, if one is deprived of structured perceptual input, as well as losing one's bearings, (a) one is likely to lose one's egocentric frame of reference itself, and (b) instead of pointing to reference points, one demonstrates their structural relation by adopting the intrinsic axes of the environment as one's own. This is prevented by providing noninformative perceptual input or by inducing subjects to imagine themselves from the outside, which makes explicit the fact of their being located relative to the world. The role of perceptual contact with a structured world is discussed in relation to sensory deprivation and imagery, appeal is made to Gibson's theory of joint egoreception and exteroception, and the data are related to recent theories of spatial memory and navigation.

Coral reefs harbor the extraordinary biodiversity and not only provide livelihoods for coastal communities but also play a crucial role in economic development generally. Unfortunately, they are in decline in Vietnam and around the world because mass coral bleaching events have become more common worldwide. However, little is discovered, about viruses that infect corals and their symbionts. Herein, we present metagenomic analyses of the viral communities in coral mucus associated with healthy and bleached coral Acropora formosa which was collected at Con Dao Island, Vietnam. Interestingly, the number of viral species in bleached specimens are higher than those in healthy status. Viruses similar to those that infect humans and some marine animals also appeared in the coral viral assemblage. The results indicated that the proportion of shared viruses were quite small, and represented extremely abundance. Among the phage identified, vibriophage and cyanophage were only presented in healthy and bleached coral, respectively. Therefore, coral-associated viruses could prospectively infect all constituents of the holobiont - coral, microalgal and microbial. Thus, we expect viruses to be illustrated prominently in the preservation and breakdown of coral health.

This article calls for the study of new immigrant destinations in a global context. Although the term “new immigrant destinations” has been primarily associated with the U.S., migration scholars of other regions and countries are examining new or emerging immigrant destinations and the implications of immigrant settlement in places that heretofore have had no notable foreign-born populations. This article argues that expanding the frame of reference for the study of new immigrant destinations provides greater insight into the ways that new geographies of immigrant settlement around the world are re-shaping dominant understandings of contemporary migration processes.

A survey of members of the Urban History Association (UHA) undertaken in March 2017 provides information about the character, views, and prospects of urban history in North America. Most UHA members are professional historians. Their age profile is balanced; women and minorities are underrepresented, though their age profile indicates that members will become more diverse. They are researching cities around the world, but focus mainly on the larger U.S. cities. Thematically, their main interests are in planning/design, race/ethnicity, politics, and housing, in that order. Most situate their work on U.S. cities within a national frame of reference; only half believe that there is something distinctively urban about cities. Those who do tend to highlight social, political, and cultural, as opposed to economic, effects. Their intellectual influences are primarily other urban historians rather than more theoretically oriented writers.

The Australasian region is home to the greatest diversity of cephalopods — squid, cuttlefish, octopuses — in the world. Yet, we know very little about these fascinating marine animals. This book provides insights into the biology and behaviour of more than 60 species. From the Giant Squid to the deadly Blue-ringed Octopus, the secret lives of cephalopods are revealed in a highly readable form with outstanding colour images and informative text. For each species there is a distribution map and identification notes which summarise the main features to look for. While the book focuses on species found in relatively shallow coastal waters, a few of the more bizarre deeper-water species are included. Naturalists, divers, reef-walkers and anglers will find the book authoritative, yet very easy to use. A comprehensive section illustrating cuttlebones will enable beachcombers to identify most of the species they are likely to encounter.

I want to dissent initially from the rather constricting frame of reference that Schubert has established in his paper. He has every right in the world to set rhetorical snares, but I have no intention of walking into them. If I may summarize, Schubert asserts that he is a spokesman for a radical new direction in the study of public law, claiming that the old ways are moribund. He further urges that we should look with envy at the creative function of the social psychologists who supplied the Supreme Court with the banners it carried in Brown v. Board of Education while we were bumbling around with historical and philosophical trivia. He concludes that instead of wasting our time with talmudic disputations on whether the Supreme Court reached the “right” or the “wrong” decisions in specific cases, we should settle down to build a firm “scientific” foundation for our discipline.Not the least amusing aspect of this indictment is that I find myself billed as the defender of the ancien régime, as the de Maistre of public law. Therefore, for the benetfit of the young and impressionistic, let me break loose from Schubert's rhetorical trap: I too think that much of the research done in public law—and, for that matter, in political science generally—has been trivial.

ABSTRACT Despite the strong emphasis on oil spill cleanup in the Oil Pollution Act of 1990, the United States still faces a major gap in its defenses against oil pollution: the lack of adequate professional ship salvage capability. Availability of preventive salvage capability would contribute to the most effective way of preventing a marine environmental catastrophe: keeping the oil, or chemicals, in the ship. This is especially important in view of the increasing age of the world tanker fleet.
