This work details the diversity and distribution of the genus Pisione Grube, 1857, Family Pisionidae Southern, 1914, on the Portuguese continental shelf. The study reports the first records for this region of the species P. guanche, P. inkoi and P. parapari, where previously P. remota was the only species reported. A detailed morphological study of the four species is presented, with a discussion of habitat preferences and biogeographic issues related to their distributional ranges. A total of 692 specimens were recorded at 48 sites. The four species coexist, with P. remota and P. parapari being the most abundant. A multivariate analysis based on morphological descriptors of 75 specimens showed a good separation of the four species. Pisione guanche and P. inkoi are characterized by a protruding notoacicula, longer in P. inkoi. These two species can be differentiated by the proportional length of the dorsal cirrus on parapodia 2 compared to parapodia 3, much longer in P. guanche, and by the number of distal teeth in the supra-acicular simple chaetae, bidentate in P. guanche and unidentate in P. inkoi. Of the four species, P. remota is the only one with an infra-acicular simple chaeta. The smallest intra-specific variability was found in P. parapari and the highest in P. guanche. The variability within species was much lower than the inter-specific variability which validated the four species of Pisione occurring in the Iberian Peninsula. This work set the meridional limit of P. inkoi and P. parapari, respectively in the western and the southern sector of the Portuguese continental shelf and the northern limit of P. guanche off the south margin of the Nazaré Canyon. Pisione guanche is here recorded for the first time in the Lusitanian biogeographic province, increasing to five the number of species known for European continental waters. A taxonomic key for the European Pisione species is given.

A new species, Goniolimon africanum is described and illustrated from Algeria and Tunisia (North Africa). This study, based on investigations of herbarium specimens and data from literature, highlights the fact that this species was collected for the first time by Ernest Cosson and provisionally named ‘Goniolimon luteolus’ nom. nud., while it was later attributed to G. tataricum. A detailed morphological study, carried out on some related European species of Goniolimon, has emphasized that African populations are taxonomically well differentiated from European ones. Its distribution, ecology and relationships are also examined. A table comparing the new species with the closest allied European species of Goniolimon is provided.

AbstractThe last-instar nymph of the nabid Lasiomerus annulatus (Reuter) is described for the first time and a diagnosis of the adult is presented. Its geographical distribution is detailed and the northern limit of its range in North America is established at 45 °37′N latitude. New phenological and ecological information is provided based on collections made in Québec from 1979 to 1985 and the bioecology is discussed, especially with regard to habitat preferences and phenological cycle.

The annotated list of hepatics of the Sochi National Park includes 80 taxa. It is based on literature records and identification of 250 specimens collected by the authors. Scapania obcordata (Berggr.) S. W. Arnell and Calypogeia fissa (L.) Raddi var. intermedia (C. E. O. Jensen) Jorg. are new for the Caucasus, 17 taxa are new for Krasnodar Territory, 41 hepatics are reported for the first time for the park. New localities of 3 red-listed European species and of 6 species included in the Red Data Book of Krasnodar Territory are cited, indicating significant conservation value of the reserve.

AbstractThe lichen genus Lecanactis Körb. in Tasmania comprises six species: L. abietina (Ach.) Körb., which is widespread and pan-temperate; L. latispora Egea & Torrente and L. neozelandica Egea & Torrente, both shared with New Zealand and with the former recorded here from the Auckland Islands for the first time; L. mollis (Stirt.) Frisch & Ertz, shared with Victoria and New Zealand; L. aff. dilleniana (Ach.) Körb., a European species recorded provisionally for Tasmania on the basis of several sterile collections; L. scopulicola Kantvilas, which is described here as new to science and apparently a Tasmanian endemic. This new taxon occurs in rocky underhangs and is characterized by a thick, leprose thallus containing schizopeltic acid, and 3-septate ascospores, 19–30 × 4.5–6 μm. Short descriptions and a discussion of distribution and ecology are given for all species. A key for all 11 Australian species of the genus is provided, including L. subfarinosa (C. Knight) Hellb. and L. tibelliana Egea & Torrente, which are recorded for Australia for the first time, and L. platygraphoides (Müll.Arg.) Zahlbr., a first record for New South Wales. Lecanactis spermatospora Egea & Torrente and L. sulphurea Egea & Torrente are also included.

For the first time the International Court of Justice has squarely faced and ruled upon the right of a third state to intervene in a case to which two other states are parties. The litigation was the Case Concerning the Continental Shelf (Tunisia/Libyan Arab Jamahiriya), Application of Malta for Permission to Intervene, Judgment of April 14, 1981. The Court unanimously denied permission to intervene, but three judges appended separate opinions which contain matters of considerable interest.

During the taxonomic study of the genus Bothriochloa from India, B. ewartiana was reported for the first time in Asia from India. Earlier, it was known only from Australia, Lesser Sunda Island (Sumbawa, Timor), Philippines (Luzon), and Papua New Guinea (Madang). We have discussed about its amphitropical disjunct distribution over a vast continental gap with respect to some variability reported in the morphological attributes. A hypothesis behind its seclusion from Far East is also discussed. The images of the habitat and habit of B. ewartiana along with its detailed comparison with a close species B. woodrovii are provided. The taxonomic limits of each Indian species of Bothriochloa along with their ranges of morphological variations and distribution have been discussed in a detail. The Indian endemic B. parameswaranii (synonym nova) has been relegated, based on the morphological study, as a new taxonomic synonym of B. insculpta. Moreover, keys to identify closely allied genera and the species of Bothriochloa in India are provided. At the end, identification, taxonomic notes and the range of variations of Dichanthium foulkesii, D. jainii & D. concanense have been discussed in a detail.

Zerumbone (ZER) isolated fromZingiber zerumbetwas previously encapsulated with hydroxypropyl-β-cyclodextrin (HPβCD) to enhance ZER’s solubility in water, thus making it highly tolerable in the human body. The anticancer effects of this new ZER-HPβCD inclusion complex via apoptosis cell death were assessed in this study for the first time in liver hepatocellular cells, HepG2. Apoptosis was ascertained by morphological study, nuclear stain, and sub-G1 cell population accumulation with G2/M arrest. Further investigations showed the release of cytochrome c and loss of mitochondrial membrane potential, proving mitochondrial dysfunction upon the ZER-HPβCD treatment as well as modulating proapoptotic and anti-apototic Bcl-2 family members. A significant increase in caspase 3/7, caspase 9, and caspase 8 was detected with the depletion of BID cleaved by caspase 8. Collectively, these results prove that a highly soluble inclusion complex of ZER-HPβCD could be a promising anticancer agent for the treatment of hepatocellular carcinoma in humans.
