Eleven Species

Lizards from the Liolaemus lineomaculatus section are endemic to Patagonia, southern South America. Three main groups are recognized within this section, one of which, the L. kingii group includes eleven species. The two northernmost distributed species of this group, L. somuncurae and L. uptoni, are endemic to a small area that partly overlaps with the Provincial Protected Area Somuncurá Plateau (within the Somuncurá massif). Knowledge available for these species is based on limited sample sizes, and mostly limited to their original descriptions; also a recent molecular phylogenetic study showed evidence for a closely related candidate species (Liolaemus sp. 4). In this paper we morphologically and genetically characterize the species L. somuncurae, L. uptoni, and L. sp. 4, and present past demographic hypotheses. We studied eighty lizards, and collected morphological and genetic data for almost all of them. The specific status of L. somuncurae and L. uptoni is supported by molecular, morphological, and distributional evidence, as well as the status of L. sp. 4; for which we recommend further morphological comparisons with other species of the L. kingii group. We also identified two novel lineages from restricted areas south of the Chubut River that we propose as candidate species. We extend previously published evidence (from plants and rodents) supporting the role of the Chubut River as an allopatric barrier. Also, in agreement with previous results based on plants, we found evidence for two refugia in northwestern Chubut, for which we encourage conservation efforts.

Internal Transcribed Spacer Sequences

A molecular phylogenetic study based on nuclear ribosomal internal transcribed spacer sequences and plastid rps16 intron sequences on the status of the genus Gymnocarpos (Paronychioideae, Caryophyllaceae) is presented. Gymnocarpos decandrus and Sclerocephalus arabicus form a strongly supported clade within a well-supported group consisting also of G. przewalskii, and the rest of Gymnocarpos. Re-examination of morphological characters also supports this conclusion. Paronychia is found to be polyphyletic, with the subgenera Paronychia and Siphonychia forming a strongly supported sister group to Gymnocarpos, whereas P. kapela and P. chlorothyrsa (representing subgen. Anoplonychia) are found to be related to Herniaria and Philippiella. A key to the 10 species recognized in Gymnocarpos is presented, as well as synoptical information on nomenclature and distributions.

Summary Ditylenchus acantholimonis n. sp. is described based on morphological, morphometric and molecular characters. It was isolated from the rhizosphere soil of Acantholimon sp. in Golestan province, Iran, and is mainly characterised by having four lines in the lateral field, a pyriform to bottle-shaped offset pharyngeal bulb, post-vulval uterine sac 36.6-56.1% of the vulva to anus distance long, and a subcylindrical to conical tail with widely rounded tip. It is further characterised by short to medium-sized females, 480-617 μm long, with a fine stylet having small rounded knobs, V = 80.8-83.6, c = 11.0-13.8, c′ = 3.3-4.6, and males with 16.0-17.0 μm long spicules. The new species was morphologically compared with six species having four lines in their lateral field, rounded tail tip and comparable morphometric data namely: D. dipsacoideus, D. emus, D. exilis, D. paraparvus, D. sturhani, and D. solani. It was also compared with two species, D. ferepolitor and D. angustus, forming a maximally supported clade in the 18S tree. The phylogenetic analyses using the maximal number of Anguinidae and several Sphaerularioidea genera based upon partial 18S and 28S rDNA D2-D3 sequences revealed that Ditylenchus is polyphyletic. In the 18S tree, the new species formed a clade with D. ferepolitor (KJ636374) and D. angustus (AJ966483); in the 28S tree it formed a poorly supported clade with D. phyllobios (KT192618) and Ditylenchus sp. (MG865719).

AbstractThree traditional tribes of Fordini, Pemphigini and Eriosomatini comprise Pemphiginae, and there are two subtribes in Fordini and Pemphigini, respectively. Most of the species in this subfamily live heteroecious holocyclic lives with distinct primary host specificity. The three tribes of Pemphigini (except Prociphilina), Eriosomatini and Fordini use three families of plants, Salicaceae (Populus), Ulmaceae (Ulums) and Anacardiaceae (Pistacia and Rhus), as primary hosts, respectively, and form galls on them. Therefore, the Pemphigids are well known as gall makers, and their galls can be divided into true galls and pseudo-galls in type. We performed the first molecular phylogenetic study of Pemphiginae based on molecular data (EF-1α sequences). Results show that Pemphiginae is probably not a monophylum, but the monophyly of Fordini is supported robustly. The monophyly of Pemphigini is not supported, and two subtribes in it, Pemphigina and Prociphilina, are suggested to be raised to tribal level, equal with Fordini and Eriosomatini. The molecular phylogenetic analysis does not show definite relationships among the four tribes of Pemphiginae, as in the previous phylogenetic study based on morphology. It seems that the four tribes radiated at nearly the same time and then evolved independently. Based on this, we can speculate that galls originated independently four times in the four tribes, and there is no evidence to support that true galls are preceded by pseudo-galls, as in the case of thrips and willow sawflies.

Reproductive Characters

Several genera of Nyctaginaceae, currently merged under Pisonia, have been described for the Indo-Pacific region. Results from a recent molecular phylogenetic study of tribe Pisonieae showed that Pisonia is non-monophyletic and comprises three well-supported lineages: one including typical Pisonia and allies (Pisonia s.str.), a clade of species which corresponds to the original description of Ceodes and a third lineage whose single representative was formerly treated under the monotypic genus Rockia. Thus, as part of an effort to achieve a natural classification for tribe Pisonieae, this work proposes to re-establish Ceodes and Rockia to accommodate taxa with inconspicuous glands on anthocarps, recognising 21 species (20 for the former and one for the latter), of which 16 are new combinations: Ceodes amplifoliacomb. nov., Ceodes artensiscomb. nov., Ceodes austro-orientaliscomb. nov., Ceodes browniicomb. nov., Ceodes caulifloracomb. nov., Ceodes coronatacomb. nov., Ceodes diandracomb. nov., Ceodes gigantocarpacomb. nov., Ceodes gracilescenscomb. nov., Ceodes lanceolatacomb. nov., Ceodes merytifoliacomb. nov., Ceodes muellerianacomb. nov., Ceodes rapaensiscomb. nov., Ceodes sechellarumcomb. nov., Ceodes taitensiscomb. nov. and Ceodes wagnerianacomb. nov. A general distribution of each species recognised in this work is also included, along with line drawings and colour pictures of representative species of Ceodes, Pisonia and Rockia and an updated dichotomous key based on reproductive characters for the nine genera (Ceodes, Cephalotomandra, Grajalesia, Guapira, Neea, Neeopsis, Pisonia, Pisoniella and Rockia) comprising the tribe Pisonieae. Résumé Plusieurs genres de Nyctaginaceae actuellement fusionnés sous Pisonia ont été décrits pour la région Indo-Pacifique. Les résultats d’une récente étude phylogénétique moléculaire de la tribu Pisonieae ont montré que Pisonia est non monophylétique et comprend trois lignées bien supportées: une comprenant Pisonia typique et ses alliés (Pisonia s.str.), un clade d’espèces qui correspond à la description originale de Ceodes et une troisième lignée dont l’unique représentant était auparavant traité sous le genre monotypique Rockia. Ainsi, dans le cadre d’un effort pour parvenir à une classification naturelle de la tribu Pisonieae, ce travail proposons de rétablir les Ceodes et Rockia pour accueillir des taxons avec des glandes discrètes sur les anthocarpes, reconnaissant 21 espèces (20 pour les premières et une pour les dernières), dont 16 sont de nouvelles combinaisons: Ceodes amplifoliacomb. nov., Ceodes artensiscomb. nov., Ceodes austro-orientaliscomb. nov., Ceodes browniicomb. nov., Ceodes caulifloracomb. nov., Ceodes coronatacomb. nov., Ceodes diandracomb. nov., Ceodes gigantocarpacomb. nov., Ceodes gracilescenscomb. nov., Ceodes lanceolatacomb. nov., Ceodes merytifoliacomb. nov., Ceodes muellerianacomb. nov., Ceodes rapaensiscomb. nov., Ceodes sechellarumcomb. nov., Ceodes taitensiscomb. nov. et Ceodes wagnerianacomb. nov. Une distribution générale de chaque espèce reconnue dans ce travail est également incluse, ainsi que des dessins au trait et des images en couleur des espèces représentatives de Ceodes, Pisonia et Rockia, et préparé une clé dichotomique mise à jour basée sur les caractères reproductifs des neuf genres (Ceodes, Cephalotomandra, Grajalesia, Guapira, Neea, Neeopsis, Pisonia, Pisoniella et Rockia) comprenant la tribu Pisonieae.

New Industry

AbstractGaslight emerged as a new industry after 1800 in Britain, but not in other countries in Europe where the technology existed as well. Among the many groups trying, it was only the firm of Boulton & Watt that succeeded in commercializing the invention for two important reasons. The first was that they possessed skills and experience related to ironworking and to making scientific instruments, both of which they used as they developed gaslight apparatus. This development involved an extensive series of experiments that ultimately had its root in James Watt's own work with pneumatic chemistry. The second reason was that they possessed many resources such as access to capital, their existing network of industrial customers, and their abilities to publicize their work. As with the steam engine, the firm proved adept at advertising. Boulton & Watt did not give their full attention to gaslight except in two spurts between 1805 and 1809, and by around 1812 they had lost almost all interest in the technology. By this time, however, they had solved many problems associated with scaling up gaslight apparatus for industrial use, they had trained many people who would go on to do further important work in the early years of the industry, and they had drawn extensive public attention to the new invention. Finally, their advertising involved elevating the status of William Murdoch as an inventor while minimizing the role of the firm.
