Full textAbstract:
Abstract Study of long-term fire histories (from fire scars on old trees) helps determine if severe fires were characteristic of the ponderosa pine (Pinus ponderosa) forests in central Idaho before the arrival of Euroamericans. Before 1895, all sample sites had average fire intervals of 10 to 22 years, implying a pattern of light to moderate surface fire. After 1895, fire intervals lengthened considerably, and severe fires became relatively common. Factors apparently influencing this change were a reduction in uncontrolled fires started by American Indians and Euroamericans; heavy livestock grazing that removed fine fuels; establishment of a fire suppression program; accumulation of slash from early logging; and development of dense conifer understories (ladder fuels). Applications of prescribed burning might reduce the risk of severe wildfires. West. J. Appl. For. 1:16-18, Jan, 1986

Full textAbstract:
This paper details the results of an excavation undertaken at Brooyar Rockshelter, southeast Queensland during August 1987. The Rockshelter was excavated as part of a larger research project focused upon the adjacent coastal region of Cooloola (McNiven 1985). The excavation had two main aims. The first was to establish a chronological framework for backed blades in the Gympie-Cooloola region, thus providing insight into the antiquity of non-stratified open sites with backed blades in the region (e.g. sandblow sites at Cooloola - McNiven 1895:15, 26, 28) (cf. Hiscock 1986). The second aim was to obtain comparative information on subsistence activities located in the hinterland region of Cooloola.

Full textAbstract:
Since Barrande (1852) first illustrated a trilobite larva, aspects of trilobite ontogeny and early development have received a great deal of attention (see Beecher, 1895; Størmer, 1942; Whittington, 1957; Hu, 1971; Chatterton, 1980). Much of this literature, however, is purely descriptive and very little has been done to incorporate these works into a biological synthesis. During the past several decades a great deal has been learned about the role of larval ecology in monitoring biogeographic distributions, cohort survivorship and taxonomic longevity among modern marine invertebrates. This growing body of knowledge has provided the basis for many new insights regarding patterns of extinction and survivorship and macroevolution evident within the fossil record (see Jablonski, 1986; Jablonski and Lutz, 1983).

Full textAbstract:
A recent phylogenetic analysis demonstrated that the solifuge genus Eremocosta (Eremobatidae), although not monophyletic, formed a strongly supported group, rendered paraphyletic by the exclusion of E. acuitlapanensis, which we herein determine is misplaced in this genus. We revise the taxonomy of the genus Eremocosta. Nine species of the 13 currently placed in the genus are retained, E. bajaensis (Muma 1986), E. calexicensis (Muma 1951), E. formidabilus (Simon 1879), E. gigas Roewer 1934, E. gigasella (Muma 1970), E. spinipalpis (Kraepelin 1899), E. striata (Putnam 1883), and E. titania (Muma 1951). Eremocosta fusca (Muma 1986) and E. montezuma (Roewer 1934) are returned to the genus Eremorhax along with E. arenarum. Eremocosta hystrix and Eremocosta acuitlapanensis (Vázquez & Gaviño-Rojas 2000) are transferred to Eremobates. We re-evaluated E. nigrimana (Pocock 1895) and determined that, since the type shows the ventrodistal concavity (VDC) diagnostic for the genus Eremocosta, it should be retained in that genus; however, because the type locality is identified as Afghanistan, far outside the range of any Eremobatidae, its status and placement remain uncertain. Eremocosta robusta (Roewer 1934) was designated nomen dubium by Muma and we maintain this designation. We provide a key to the species of Eremocosta and provide a description of the female of E. gigas.

Época de relevo na produção nacional de mobiliário, o grupo de peças do Museu Medeiros e Almeida é representativo da excelente qualidade estética e técnica atingida neste período, o qual tantas vezes cruza a madeira exótica chegada do Brasil, com o gosto nacional da madeira entalhada, pouco profunda e seguindo padrões estéticos rococó em que as formas se contraem, desaparecendo o excesso de volumes, as ondulações acentuadas e a ostentação dourada características do barroco.
A colecção integra tipologias variadas que permitem observar a adesão aos padrões de gosto inglês e francês, cuja simbiose se revelou no móvel português.

Hubbard Glacier, the largest tide-water glacier in North America, has advanced since it was first mapped in 1895 by moving a protective submarine moraine into the entrance of Russell Fiord. In May 1986, a weak surge of the Valerie tributary of Hubbard Glacier caused the glacier to block the fiord entrance, converting the body of water into a large glacier-dammed lake. This lake filled to a height of 25.5 m and stored 5.4 km3 of water before it burst out on 8 October 1986, producing a peak flow of 105 000 m3 s−1 averaged for 1 h.Hubbard Glacier is expected to continue advancing because its accumulation area ratio (AAR) is 0.95, which is unusually large. Such an advance would undoubtedly block Russell Fiord again. If this happens, it is predicted that the lake will fill to a height of 39 m over a period of 1.1–1.5 years and then overflow into the Situk River near Yakutat. This, in turn, would increase the average flow of that small stream from ils present rate of between 10 and 15 ms−1 to an estimated annual average discharge of 230 m s−1. Such an increase in flow would be expected to flood and erode forest lands, fish habitats, subsistence fishing camps, archaeological sites, and roads. At the same time, the increased water depth in Russell Fiord could be expected to increase the calving rate of Hubbard Glacier, potentially threatening the stability of its calving terminus.

RESUMO Professora universitária de ciências e professora do ensino liceal, Seomara da Costa Primo (Lisboa, 1895 - Amadora, 1986) distinguiu-se como investigadora, autora (nomeadamente de manuais) e ilustradora. A sua ação incorporou também o associativismo docente, a participação na imprensa e missões de estudo no estrangeiro. Foi uma mulher do seu tempo, uma intelectual, que defendeu um papel ativo das mulheres na sociedade e lutou pela sua educação, afirmando-se num universo essencialmente masculino. O seu percurso vital demonstra que percorreu algumas das instituições de referência da época e dialogou em arenas significativas de debate, afirmando-se como uma personalidade ímpar que também circulou internacionalmente em missões científicas. A penumbra em que tem sido mantido o seu nome e a sua vida deve ser iluminada por uma recolocação na galeria das mulheres ilustres que representam um tempo e um modo de ocupar o espaço público e de afirmar a profissão docente.

Full textAbstract:
The tribe Meteorini includes two genera, Meteorus and Zele, which are koinobiont endoparasitoids of larval Lepidoptera and Coleoptera. More than 300 species are known, about one fifth of which occur in the Western Palearctic. Here, we revise the Western Palearctic species, based partly on traditional approaches and partly on molecular analysis of recent Swedish and Finnish material. For the analyses of phylogenetic relationships and cryptic species diversity, we coded 17 morphological characters and sequenced two markers, 28S D2 (649 bp) and CO1 (665 bp). More than 1 970 specimens representing 54 species of Meteorus Haliday and 5 species of Zele Curtis were studied; of these, 177 specimens representing 41 species were sequenced. Seven new species are described, all from the Fennoscandian material: Meteorus artocercus sp. nov., M. densipilosus sp. nov., M. eklundi sp. nov., M. longipilosus sp. nov., M. sibyllae sp. nov., M. stenomastax sp. nov., and M. subtilisulcus sp. nov. Four new synonyms are introduced: Z. chlorophthalmus (Spinola 1808), syn. nov. for M. pallidus (Nees 1812), M. punctifrons Thomson 1895, syn. nov. for M. varinervis (Tobias 1986), M. melanostictus Capron 1887, syn. nov for M. monachae (Tobias 1986), and M. tenellus Marshall 1887, syn. nov. for M. boreus (Tobias 1986). Meteorus tenellus is removed from synonymy with M. cinctellus. Sequence analysis indicated the presence of at least 12 additional cryptic species but these cannot be separated morphologically at this point and, therefore, we do not describe them here. The phylogenetic results suggest that Zele should be included within Meteorus but we refrain from formal changes of the generic classification until more comprehensive phylogenetic analyses of the tribe can be completed. A key to the known Western Palearctic species is presented.

Full textAbstract:
Ampelocalamus Chen et al. (1981: 332) and Drepanostachyum Keng (1983: 15) are two subtropical clumping genera in the tribe Arundinarieae Ascherson & Graebner (1902: 770) of the subfamily Bambusoideae Luerssen (1893: 451) in the Poaceae (Barnhart 1895: 7) (Bamboo Phylogeny Group 2012). These two genera were confused by the transfer of most species from Ampelocalamus to Drepanostachyum (Keng 1986, Yi 1993, Yi et al. 2008). Ampelocalamus differs from Drepanostachyum in several characters: Ampelocalamus has subscandent culms, a corky collar frequently present on the nodal sheath scars, pendulous spikelets, and adaxially distally glabrous culm sheaths, while Drepanostachyum has self-supporting culms, nodal sheath scars without a corky collar, erect or spreading spikelets, and adaxially distally scabrid culm sheaths (Chen et al. 1981, Keng 1983, Li 1997, Stapleton et al. 2005, Li & Stapleton 2006). Ampelocalamus comprises ca. 14 species distributed from the central Himalayan region to southern China with 13 species endemic to China (Li & Stapleton 2006).

Full textAbstract:
The generic classification of Lymexylidae is reexamined, particularly with reference to the Australian fauna. The transfer of the Madagascar genus and species Alcestoma serropalpoides Fairmaire (1895) from Melandryidae to Lymexylidae, proposed by Nikitsky in Nikitsky et al. (1998), is confirmed and the genus is considered to be a senior synonym of Protomelittomma Wheeler (1986), syn. n. The occurrence of the genus Alcestoma in Australia is noted and a new species, Alcestoma queenslandicum, sp. n. is described from northern Queensland. The genus Arractocetus Kurosawa (1985) is also recorded for the first time from Australia, but the species is not described. A new genus, Leptonetron, gen. n., is described, based on the type species Atractocerus victoriensis Blackburn, 1891, which is considered to be a senior synonym of Atractocerus tasmaniensis Lea, 1917, syn. n. A key is provided for the Australian genera and species of Lymexylidae and the evolution of the family is briefly discussed.

Full textAbstract:
Cyliosoma Pocock, 1895, the oldest available genus name for Australian giant pill-millipedes, is revised with a redescription of its type species, Sphaerotherium angulatum Butler, 1878. All 16 species of Epicyliosoma Silvestri, 1917 are transferred to Cyliosoma, together with two species, Sphaerotherium fraternum Butler, 1872 and S. marginepunctatum Karsch, 1881, which are redescribed here. A new phylogenetic analysis of the Sphaerotheriida was conducted using 100 morphological characters and including two Cyliosoma species and four recently described or redescribed species of the family Zephroniidae. Most character states are illustrated for Cyliosoma, including the first SEM images of a member of the genus. Cyliosoma is neither closely related to the South African Sphaerotherium, nor to the other Australian genus, Procyliosoma, and is here placed in a new family, Cyliosomatidae. The monotypic Australian genus Cynotelopus Jeekel, 1986 is also referred to the Cyliosomatidae. The current position of the Cyliosomatidae is in a trichotomy including the South African Sphaerotheriidae and the Malagasy–Indian Arthrosphaeridae.

Current work on cone beetle molecular identification and semiochemicals requires a rapid and reliable method for sexing adult beetles. Head microsculpturation (Schwarz 1895; Wood 1982), overall beetle length, head width, and internal genital structures (or parts of them) visible when extruded through the genital opening (Lyons 1956) have been suggested as characters to sex adult Conophthorus. Herdy (1959) pointed out that abdominal tergite morphology could be used to distinguish males from females. The latter seems to be the most reliable, non-destructive way to sex Conophthorus specimens. Published illustrations (Kinzer and Ridgill 1972) have been found difficult to interpret by many researchers. To increase the reliability in sexing adult Conophthorus beetles, we prepared scanning electron micrographs (SEMs) of the terminal abdominal tergites of adult males and females, which we present here, clearly showing the diagnostic features of each sex.

AbstractRenewed popular interest in the Pinkertonovshchina – pre-Revolutionary, Western-styled detective fiction – invites a closer look at this fascinating phenomenon. An examination of the original serial's reception among young readers holds out clues to the psychological motivations of those who devour popular cultural genres in times of social flux. Memoirs and letters by Valentin Kataev (1897-1986), Leonid Borisov (1897-1972), and Sergei Esenin (1895-1925), who had all experienced the first Pinkerton craze as 10- and 12-year-olds, indicate that these colorful, readily accessible parables of Manichean justice in exotic locales allowed young readers to displace their own anxieties about an all-too-confusing domestic situation in the wake of the 1905 Revolution and the subsequent "Reaction". In this, the Russian Pinkertons of the 1900s and '10s functioned in much the same way as American comic books of the 1940s and '50s – another cheaply priced, fixed-format, violent, and markedly graphic (i.e., visual) genre which captivated young readers during a highly reactionary period in their nation's history.

Full textAbstract:
Lejeuneaceae is the largest family of the liverworts with about 1700 currently accepted species (He & Zhu 2011, He et al. 2012), but some of them are poorly known and their status is still unclear. Leptolejeunea himalayensis Pandé & Misra (1943: 168) is known only from India and previously suspected of belonging to one member of Lejeunea Libert (1820: 372) (Awasthi 1986). Leptocolea mirpurensis Khan (1957: 23) from Bangladesh has never been studied since its first description in 1957. Although the types of the two taxa were not available for our study, the original description and illustrations (Pandé & Misra 1943, Khan 1957) undoubtedly indicate that Leptolejeunea himalayensis and Leptocolea mirpurensis are conspecific with Lejeunea cocoes Mitten (1861: 114) and Cololejeunea raduliloba Stephani (1895: 251), respectively. Lejeunea cocoes has been reported for India (Singh & Nath 2007, Manju et al. 2012), and is also known in China, Indonesia, Malaysia, Papua New Guinea, and Sri Lanka (So & Zhu 1998, Zhu & So 2001, Lee 2013), furthermore from Chagos, Diego Garcia (Seaward et al. 2006) and from the Fiji Islands (Pócs et al. 2013). Cololejeunea raduliloba, a paleotropical species (Zhu & So 2001), is newly reported for Bangladesh.

Zootaxa 4873, no. 1 (November 6, 2020): 1–132. http://dx.doi.org/10.11646/zootaxa.4873.1.1.
Full textAbstract:
The genera Psalistops Simon, 1889, Trichopelma, Simon, 1888 and Cyrtogrammomma Pocock, 1895 are revised and included in cladistics analyses including almost all species of these genera. In order to test previous morphological hypotheses on the relationships of Barychelidae, Paratropididae and Theraphosidae and because of the controversial taxonomic position of Psalistops and Trichopelma, a set of terminal taxa representing all subfamilies of Paratropididae (Paratropidinae, Glabropelmatinae), Barychelidae (Barychelinae, Sasoninae, Trichopelmatinae) and most theraphosid subfamilies were included, as well as a diplurid, a nemesiid, and a pycnothelid, the later used to root the cladogram. The matrix with 66 terminal taxa, 2 continuous and 93 discrete characters was analysed with TNT 1.5. We found that Trichopelmatinae is not a monophyletic group, and Psalistops is transferred to Theraphosidae, as well as the barychelid genus Cyrtogrammomma and the paratropidid genus Melloina Brignoli. Cyrtogrammomma was retrieved as the sister group of Trichopelma, and Melloina as the sister group of Holothele Karsch. Psalistops was retrieved as the sister group of Reichlingia Rudloff, and the clade with these two genera is the most basal in Theraphosidae. Barychelidae was found to be monophyletic and the sister group of Theraphosidae. Paratropididae was retrieved as the sister group of Barychelidae + Theraphosidae. The relationship and possible synapomorphies of the three families are herein discussed. This is the first time since Raven (1985) that representatives of all barychelid (Barychelinae, Sasoninae, Trichopelmatinae), paratropidid (Paratropidinae, Glabropelmatinae) and most theraphosid subfamilies have been included in a morphological cladistic analysis. Psalistops comprises two species, P. melanopygius Simon, 1889 (type species) and P. colombianus sp. nov. Psalistops montigena Simon, 1889, P. tigrinus Simon, 1889 and P. zonatus Simon, 1889 are synonymized with P. melanopygius Simon, 1889. Psalistops fulvus Bryant, 1948, P. hispaniolensis Wunderlich, 1988 (fossil), P. maculosus Bryant, 1948, P. venadensis Valerio, 1986 and P. steini (Simon, 1889) are transferred to Trichopelma. Psalistops gasci Maréchal, 1996 is transferred to Hapalopus Ausserer (Theraphosidae); P. opifex (Simon, 1889) and P. solitarius (Simon, 1889) are transferred to Schismatothele Karsch, 1879 (Theraphosidae). Schismatothele solitarius (Simon, 1889) n. comb. is synonymized with Schismatothele lineata Karsch, 1879, n. syn. Psalistops nigrifemuratus Mello-Leitão, 1939 is probably a nemesiid or pycnothelid, and herein considered as nomen dubium in Pycnothelidae. Trichopelma comprises 22 species: Trichopelma nitidum Simon, 1888 (type species), T. coenobita (Simon, 1889), T. steini (Simon, 1889), T. affine (Simon, 1892), T. cubanum (Simon, 1903), T. maculatum (Banks, 1906), T. zebra (Petrunkevitch, 1925), T. banksia Özdikmen & Demir, 2012, T. insulanum (Petrunkevitch, 1926), T. fulvus (Bryant, 1948) n. comb., T. laselva Valerio, 1986, T. venadensis (Valerio, 1986) n. comb., T. huffi sp. nov., T. gabrieli sp. nov., T. tostoi sp. nov., T. goloboffi sp. nov., T. juventud sp. nov., T. laurae sp. nov., T.bimini sp. nov., T. loui sp. nov., T. platnicki sp. nov., and T. hispaniolensis Wunderlich, 1988 n. comb. (fossil). Trichopelma maculosus (Bryant, 1948) n. comb. is synonymized with P. fulvus Bryant, 1948; T. corozalis (Petrunkevitch, 1929) is synonymized with T. insulanum (Petrunkevitch, 1926). Trichopelma astutum Simon, 1889 is transferred to Euthycaelus Simon, 1889, and T. maddeni Esposito & Agnarsson, 2014 to Holothele Karsch, 1879 (Theraphosidae). Trichopelma flavicomum Simon, 1891 is transferred to Neodiplothele (Barychelidae, Sasoninae). The species T. illetabile Simon, 1888, T. spinosum (Franganillo, 1926), T. scopulatum (Fischel, 1927) and T. eucubanum Özdikmen & Demir, 2012 are considered as nomina dubia. Cyrtogrammomma comprises two species: C. monticola Pocock, 1895 (type species) and C. raveni sp. nov.

Full textAbstract:
AbstractThe following extracts come from a memoir of philosophical life between the wars and after, written in the 1970s by the Anglo-Scottish philosopher Louis Arnaud Reid (1895–1986).2 Today Reid is best known for his writings on aesthetics, and as the holder of the foundation chair in the philosophy of education at the University of London. Reid will also be familiar to those who have read A.J. Ayer's account of Ayer's appointment to the chair of philosophy at London, for Reid was the candidate strongly preferred by the philosophers on the selection committee.3 Reid regretted the rise of logical positivism in the later 1930s because it introduced a break with the earlier world of humane philosophical discourse.In these extracts, edited by his grandson, Reid begins by giving a sense of the breadth of topics covered in philosophical conferences in the 1920s, before sketching some of the characters involved. He mentions of course a number of figures still familiar to us, from Moore to Russell to Wittgenstein, but tries more generally to give an impression of a philosophical world which is now largely lost. These are themes he continues elsewhere in the book, where he discusses the people he knew at Edinburgh, Aberystwyth, Liverpool, Newcastle and London.

The ArgumentCarl Gottfried Neumann was born in Königsberg, Prussia, in 1832 and died in Leipzig in 1925. His father was the physicist Franz Neumann (1798–1895), notable for his contributions not only to the study of electricity and magnetism but also to the development of physics education in nineteenth-century Germany. Carl Neumann studied at the University of Königsberg and received his doctorate in 1855 with a work on the application of elliptic integrals to mechanics (Neumann 1856). In 1858 he became Privatdozent, and in 1863 Professor of Mathematics at Halle. Later that same year he moved to Basel, and in 1865 he became Ordinary Professor of Mathematics at Tübingen. Finally in 1868 he was appointed Professor of Mathematics at Leipzig, a post he held until he retired in 1911; of the two mathematics professorships at Leipzig, this was the one formerly held by F. A. Möbius, and it was officially devoted to “the higher mathematics, especially physics” (quoted in Jungnickel and McCormmach 1986, 1:181). So Neumann's academic career, along with his role as one of the founding editors of the Mathematische Annalen beginning in 1869, can be seen as reflecting the enormous advance in mathematical sophistication that German physics underwent in the latter part of the nineteenth century.

Full textAbstract:
AbstractA large sample (>100 specimens) of the fossil rodent Thisbemys Wood, 1959, from the early Eocene (late Bridgerian; Br3) Washakie Formation of Wyoming is described. Two species are recognized: a new species, T. intermedius n. sp., and Thisbemys cf. T. uintensis (Osborn, 1895). The large sample size of the former has allowed for a detailed study of variation in size and morphology within the species based on tooth-wear. As a result, some systematic changes in the species included in this genus are suggested: (1) T. brevicrista Ostrander, 1986, is limited to the holotype, and all specimens previously referred to T. brevicrista are likely referable to T. plicatus Wood, 1962; (2) statistical analysis supports the separation of T. plicatus from T. corrugatus Wood, 1959, based on its smaller size and less-crenulated cheek teeth, which corroborates their existence at different horizons (T. plicatus earlier Bridgerian [Br2], T. corrugatus late Bridgerian [Br3]); (3) Paramys delicatior Leidy, 1871, is suggested as the senior synonym of T. plicatus Wood, 1962; (4) T. perditus Wood, 1962, is limited to the early Eocene (Washatchian: Wa1-6); and (5) all specimens previously referred to T. nini Wood, 1962, except the holotype, are referred to T. perditus (fide Korth, 1984; contra Anderson, 2015).UUID: http://zoobank.org/59c101e2-cd55-4dce-aeea-3da48c4fbd53

Psilidae: Chamaepsila tenebrica (Shatalkin, 1986) is a new addition to the West Palaearctic fauna (recorded from the Czech Republic and Slovakia); Ch. andreji (Shatalkin, 1991) and Ch. confusa Shatalkin & Merz, 2010 are recorded from the Czech Republic (both Bohemia and Moravia) and Ch. andreji also from Austria for the first time, and Ch. unilineata (Zetterstedt, 1847) is added to the fauna of Moravia. Also Homoneura lamellata (Becker, 1895) (Lauxaniidae) and Cremifania nigrocellulata Czerny, 1904 (Cremifaniidae) are first recorded from Moravia and Copromyza pseudostercoraria Papp, 1976 (Sphaeroceridae) is a new addition to faunas of both the Czech Republic (Moravia only) and Slovakia, and its record from Moravia represents a new northernmost limit of its distribution. Pseudoseps signata (Fallén, 1820) (Piophilidae), an endangered species in the Czech Republic, is reported from Bohemia for second time. Photographs of Chamaepsila tenebrica (male), Pseudoseps signata (living female), Homoneura lamellata (male), Cremifania lanceolata (male) and Copromyza pseudostercoraria (male) are presented to enable recognition of these species.

Full textAbstract:
Monstrilloids are copepods that live freely in plankton without feeding but have parasitic immature stages that develop within infected benthic molluscs and polychaetes. Because of their incompletely known life cycles and the difficulty of matching conspecific males and females, it has been difficult to assess their true diversity anywhere on earth. The monstrilloid fauna of the Mediterranean and Black seas (MBS) has been investigated for over 140 years, during which time four phases of study can be recognized. The initial list of MBS monstrilloids recorded during the first phase (1877–1893) grew only slowly for decades afterwards during the second phase (1895–1952) because of patchy sampling and a dearth of formal taxonomic descriptions. The third phase (1957–1986) featured little new work at all. During the most recent fourth phase since 1992, a reappraisal with heed to nomenclatural rules and upgraded descriptive standards has led to the realization that many nominal species of MBS monstrilloids are invalid or doubtful. Furthermore, some that have been frequently recorded, such as Monstrilla grandis, Cymbasoma longispinosum, and C. rigidum, may actually be undescribed representatives of widespread species groups. We provide an updated annotated checklist of MBS monstrilloids that includes 21 supposedly valid nominal species or species-groups. This rather high regional diversity will likely grow if future zooplankton surveys in the highly heterogeneous and extensive coastal systems of the MBS pay due attention to this intriguing group of copepods.

The First International Congress for Analytical Psychology was held in Zurich from 7 to 12 August 1958. On this occasion a small group of Israeli psychologists, represented by Erich Neumann, was accepted as a charter group member of the International Association for Analytical Psychology (IAAP), which marked the foundation of the Israel Association of Analytical Psychology. The history leading up to this official birth date is mainly associated with the efforts of Erich Neumann – and rightly so; however, a number of other therapists, scholars and patients have been forgotten or deleted from this historical narrative, to their detriment. While I was working on the edition of the correspondence between C. G. Jung and Erich Neumann I came across their names, which were often only casually mentioned re some episode, and I have since tried to find out their stories and what happened to them. In this article I discuss the contributions to the development of analytical psychology in British Mandate Palestine, later Israel, of two such figures, Max M. Stern (1895–1982) and Margarete Braband-Isaac (1892–1986). Both had been in personal contact with C. G. Jung and built a bridge between the isolated Jewish therapists in British Mandate Palestine and the Zurich circles. In Tel Aviv they collaborated for a while with Neumann, with whom for different reasons both fell out. The article shows the cause of these controversies with Neumann and tries to find out why those two characters were historically marginalized.

Full textAbstract:
Giesbrecht (1895) was the first to report that the luminescence produced by marine copepods was produced by certain ‘skin glands’. In Pleuromamma abdominalis he described specific sub-cuticular cells which were responsible for the production and secretion of luminous material; such cells always contained a greenish-yellow secretion whilst non-photogenic cells were colourless. The only published histological study of luminous cells in copepods is that by Clarke et al. (1962). These authors reported numerous paired cells in the head of Metridia longa, each pair opening through a common pore, the distribution of which was correlated with areas of fluorescence. Clarke et al. (1962) further showed that the cells in each pair had different staining characteristics, and suggested that each of the two cell types produced a different component of the luminescent system, proposed as ‘luciferin’ and ‘luciferase’ respectively. They hypothe-sized that when stimulated, each cell secreted its contents, generating light as the materials combined in the surrounding seawater. Although there has been much work carried out on the physical characteristics and kinetics of copepod luminescence (e.g. David & Conover, 1961; Clarke et al., 1962; Barnes & Case, 1972; Bityukov & Evstigneev, 1982; Herring, 1983, 1988; Evstigneev, 1983, 1984, 1986; Latz et al., 1988) there is still little known of the comparative distribution of luminous cells in a range of copepod species, and even less is known of their detailed structure.

AbstractHubbard Glacier is the largest tidewater glacier in North America. In contrast to most glaciers in Alaska and northwestern Canada, Hubbard Glacier thickened and advanced during the 20th century. This a typical behavior is an important example of how insensitive to climate a glacier can become during parts of the calving glacier cycle. As this glacier continues to advance, it will close the seaward entrance to 50 km long Russell Fjord and create a glacier-dammed, brackish-water lake. This paper describes measured changes in ice thickness, ice speed, terminus advance and fjord bathymetry of Hubbard Glacier, as determined from airborne laser altimetry, aerial photogrammetry, satellite imagery and bathymetric measurements.The data show that the lower regions of the glacier have thickened by as much as 83 m in the last 41 years, while the entire glacier increased in volume by 14.1 km 3. Ice speeds are generally decreasing near the calving face from a high of 16.5 md −1in1948 to11.5 md −1in 2001. The calving terminus advanced at an average rate of about 16 m a−1 between 1895 and 1948 and accelerated to 32 m a−1 since 1948. However, since 1986, the advance of the part of the terminus in Disenchantment Bay has slowed to 28 m a−1. Bathymetric data from the lee slope of the submarine terminal moraine show that between 1978 and 1999 the moraine advanced at an average rate of 32 m a−1, which is the same as that of the calving face.

Abstract. Trace-element analysis of ostracod shells has been shown to be a powerful tool in Quaternary palaeoenvironmental reseach (e.g. Chivas et al., 1986). Particular use has been made of Sr/Ca and Mg/Ca ratios in ostracod shells as palaeosalinity and palaeotemperature indictors. However, work on trace elements such as Cd, Zn, Cu and Ba in benthic foraminifera (e.g, Boyle, 1981) has shown that chemical cleaning of the shell is necessary to remove surface-bound contaminants, so that only the lattice-bound elements are analyzed. This note describes the application of selected cleaning methods to non-marine ostracod shells and evaluates their effect on shell chemistry with particular reference to Sr, Mg, Mn and Fe.Samples of ostracod shells were taken from late Quaternary lacustrine marls from Wallywash Great Pond, Jamaica. Adult valves of the genus Cypretta Vàrva 1895 were selected at random and subjected to one of three cleaning methods as follows.Method A: shells cleaned thoroughly with a clean nylon paint brush (0000) and deionised water, until all visible particles (under x40 magnification) had been removed. Shells cleaned by methods B and C were also initially treated in this way.Method B: shells cleaned in a basic hydroxylamine hydrochloride solution at 80°C for 30 minutes and then rinsed in deionised water (Boyle, 1981).Method C: shells cleaned in a basic sodium dithionite complexing reagent at 80°C for 30 minutes and then rinsed with deionised water (Boyle, 1981).Nine individual valves were cleaned using each method. Once cleaned, the valves were individually dissolved in 3ml. . .

Full textAbstract:
A large (est. volume 2.8 × 106 m3) landslide occurred in sensitive Leda clay on the east bank of the South Nation River at Lemieux, Ontario (45.4°N, 75.06°W), on June 20, 1993. The earthflow involved an area of about 17 ha and retrogressed a total of 680 m, 555 m into the flat plain above the river. No lives were lost but a motorist was injured when he drove into the landslide crater. The 1993 landslide occurred 4.5 km downstream of the well-known 1971 South Nation River landslide along a stretch of river that had experienced other historical landslides in 1895 and 1910. A band of earlier, undated, retrogressive sliding, between 100–130 m in width, was present at the base of the slope that failed in 1993, and the earthflow was probably triggered by a reactivation of these failures. Borehole information obtained in 1986 and 1987 in the vicinity of the landslide indicates that a zone of soft, sensitive marine clay existed beneath the flat farmland, which was overlain by a stiffer cap consisting of laminated marine-estuarine sands and deltaic silts and sands. The morphology of the debris suggests a mechanism that involves the fluidization of much of the landslide mass and subsidence, translation, and rotation of cap blocks. The stability number for the site was approximately 9.6, suggesting that the flow could have occurred as a result of extrusion of the soft sensitive clay layer due to undrained cap loading. Landslide debris temporarily blocked the South Nation River, causing flooding upstream and adversely affecting water quality downstream. Key words : landslide, earthflow, sensitive clay, debris hazards, water quality.

Abstract. The Little Ice Age maximum extent of glaciers in Iceland was reached about 1890 AD and most glaciers in the country have retreated during the 20th century. A model for the surface mass balance and the flow of glaciers is used to reconstruct the 20th century retreat history of Hoffellsjökull, a south-flowing outlet glacier of Vatnajökull, which is located close to the southeast coast of Iceland. The bedrock topography was surveyed with radio-echo soundings in 2001. A wealth of data are available to force and constrain the model, e.g. surface elevation maps from ~1890, 1936, 1946, 1986, 2001, 2008 and 2010, mass balance observations conducted in 1936–1938 and after 2001, energy balance measurements after 2001, and glacier surface velocity derived by DGPS and correlation of SPOT5 images. The 21% volume loss of this glacier in the period 1895–2010 is realistically simulated with the model. After calibration of the model with past observations, it is used to simulate the future response of the glacier during the 21st century. The mass balance model was forced with an ensemble of temperature and precipitation scenarios from a study of the effect of climate change on energy production in the Nordic countries (the CES project). If the average climate of 2000–2009 is maintained into the future, the volume of the glacier is projected to be reduced by 30% with respect to the present at the end of this century, and the glacier will almost disappear if the climate warms as suggested by most of the climate change scenarios. Runoff from the glacier is predicted to increase for the next 30–40 years and decrease after that as a consequence of the diminishing ice-covered area.

Full textAbstract:
In January 1986, a 133 m ice core, with an estimated age at the bottom of 300-350 years, was collected (using an electromechanical drill) on Dolleman Island (70° 35.2′S, 60°55.5′ W; 398 ma.s.l.; 10 m temperature −16.75°C). The site lies on the east coast of the Antarctic Peninsula and has a continental-type climate dominated by perennial sea ice in the Weddell Sea. The core is being analysed for a range of chemical impurities, in order to assess their potential as indicators of past climate.High-resolution (10-15 samples a−1) continuous profiles of the anionic species Cl−1, NO3− and SO42−, together with the cation Na+, have been measured on a section of the core from 26 to 71 m depth. The core has previously been dated between 0 and 32 m depth using the δ18O profile (Peel and others 1988). Lack of δ18O data for the section 32-71 m forced us to seek an alternative method of dating.Biogenic outgassing of sulphurous gases from the ocean and subsequent photochemical oxidation contribute an excess of sulphate over that derived from the marine aerosol. We show that excess sulphate, calculated as(concentrations in Eq. 1−1 and assuming that all measured Na+ is derived from sea salt), is highly seasonal in character, and annual horizons are well preserved over the whole of the core. This enabled us to determine the chronology to 71 m depth, and date the bottom of this section as 1844 ± 5 years.Cl− is derived mainly from sea salt. Its profile in the core is also seasonal in character, with peaks that tend to occur in late summer, reflecting the period of minimum sea-ice extent in the Weddell Sea, and therefore maximum source area for the uptake of sea salt. From instrumental meteorological records, Limbert (1974) showed that there were three extended periods of warm or cold weather in the Antarctic Peninsula between 1903 and 1944. During the two 4 year cold periods, when the summer break-up of sea ice in the Weddell Sea is likely to have been reduced, we found that the annual flux of Cl− to the Dolleman Island snow-pack was lower than the average. Conversely, the 3 year warm period showed a peak in the values of annual flux of Cl−. We therefore propose that Cl− can be used as a palaeoclimatic indicator for sea-ice extent.Extending our chloride data into the latter half of the nineteenth century (before the earliest continuous instrumental records for the Antarctic), we found three distinct peaks in the values of annual flux of Cl−. We suggest that the period 1850-60 was marked by a decrease in Weddell Sea ice extent (due perhaps to a warm period), followed by an extended period of increased sea ice. There were then two periods of much-reduced sea ice during (approximately) 1885-1890 and 1895-1900, with an intervening period of greatly increased ice coverage. These events are in good agreement with the warm and cold periods which Aristarain and others (1986) identified in the deuterium profile from James Ross Island.
