Flower visitors and pollination in the Oriental (Indomalayan) Region

Current knowledge of flower visitors and pollination in the Oriental Region is summarised. Much less is known about pollination than seed dispersal and the coverage of habitats and taxa in the region is very uneven. The available evidence suggests that pollination in lowland forests is dominated by highly social bees (mainly Trigona and Apis species), with beetles probably the next most important group, followed by other bees and flies. In comparison with the better-studied Neotropics, large solitary bees, moths, Lepidoptera and vertebrates are relatively less important. These differences are greatest in the canopy of the lowland dipterocarp forests of Southeast Asia, where they probably reflect the unique temporal pattern of floral resource availability resulting from 'general flowering' at supra-annual intervals. Apis bees (but not Trigona species) are also important in most montane, subtropical and non-forest habitats. Apart from the figs (Ficus spp.), there are few well-documented examples of plant species visited by a single potential pollinator and most plant-pollinator relationships in the region appear to be relatively generalised. The small sizes of most pollinators and the absence of direct human exploitation probably make pollination mutualisms less vulnerable to failure as a result of human impacts than dispersal mutualisms, but more subtle impacts, as a result of altered gene flows, are likely to be widespread. On current evidence, pollination systems in the Oriental Region do not require any specific conservation action, but this review reinforces arguments for making the preservation (or restoration) of habitat connectivity the major focus of Oriental conservation.     

Frugivory and seed dispersal by vertebrates in the Oriental (Indomalayan) Region

Current knowledge of frugivory and seed dispersal by vertebrates in the Oriental Region is summarized. Some degree of frugivory has been reported for many fish and reptile species, almost half the genera of non-marine mammals and more than 40% of bird genera in the region. Highly frugivorous species, for which fruit dominates the diet for at least part of the year, occur in at least two families of reptiles, 12 families of mammals and 17 families of birds. Predation on seeds in fleshy fruits is much less widespread taxonomically: the major seed predators are colobine monkeys and rodents among the mammals, and parrots, some pigeons, and finches among the birds. Most seeds in the Oriental Region, except near its northern margins, are dispersed by vertebrate families which are endemic to the region or to the Old World. Small fruits and large, soft fruits with many small seeds are consumed by a wide range of potential seed dispersal agents, including species which thrive in small forest fragments and degraded landscapes. Larger, bigger-seeded fruits are consumed by progressively fewer dispersers, and the largest depend on a few species of mammals and birds which are highly vulnerable to hunting, fragmentation and habitat loss.     

Revision of Gangesia (Cestoda: Proteocephalidea) in the Indomalayan Region: Morphology,Molecules and Surface Ultrastructure

Tapeworms of Gangesia Woodland, 1924 (Cestoda: Proteocephalidea) parasitic in freshwater fishes in the Indomalayan Region were critically reviewed. Evaluation of type specimens and newly collected materials from Bangladesh, Cambodia and India, as well as critical examination of extensive literature have shown that only the following four species, instead of 48 nominal species of Gangesia and Silurotaenia Nybelin, 1942 reported from this region (36 new synonymies proposed), are valid: Gangesia bengalensis (Southwell, 1913), type-species of the genus and most common parasite of Wallago attu (Siluridae), G. macrones Woodland, 1924 typical of Sperata seenghala (Bagridae), both species characterized by the possession of two circles of hooks on the rostellum-like organ and several rows of hooklets on the anterior margins of suckers; G. agraensis Verma, 1928 from W. attu (typical host), which has the scolex with only one circle of hooks and 1–3 incomplete rows of tiny hooklets on the suckers; and G. vachai (Gupta and Parmar, 1988) n. comb. from several catfishes, which possesses 4–6 circles of hooks and 5–11 rows of hooklets on the anterior half of suckers. Scolex morphology, including surface ultrastructure (microtriches), of all but one species (G. vachai) is described for the first time using scanning electron microscopy. A phylogenetic analysis based on the partial sequences encoding the large nuclear ribosomal subunit RNA gene has shown that three Indomalayan species, namely G. bengalensis, G. macrones and G. vachai, form a monophyletic group within Gangesia, whereas G. agraensis tends to form a clade with the Palaearctic species of the genus. A table with differential characters of all species from the Indomalayan Region is also provided together with a key to identification of genera of the subfamily Gangesiinae. The present study demonstrates that species of Silurotaenia do not occur in the Indomalayan region.     

Stukalinia, a new substitute generic name for fossil crinoid Lobocrinus Stukalina non Wachsmuth and Springer 1897 (Echinodermata: Crinoidea)

A new generic name, Stukalinia nom. nov., is proposed for a fossil Ordoviacian crinoid that currently has the preoccupied fossil generic name Lobocrinus Stukalina 1982 non Wachsmuth and Springer (1897), along with a new family name, Stukaliniidae nom. nov., instead of the illegitimate family name Lobocrinidae Stukalina (1982).     

New myrmicine ant genera from the Oriental Region Hymenoptera: Formicidae

Abstract. Four new myrmicine ant genera are described from the Oriental Region. Vombisidris gen.n. (twelve species) is predominantly an arboreal genus that ranges from India to Queensland, with the majority of species in Malaysia and Indonesia. Rotastruma gen.n. (two species) is known from China, Singapore, and East Malaysia and is also arboreal. Tetheamyrma gen.n. is monotypic and known only from a single leaf litter sample from East Malaysia. The three species of Kartidris gen.n. are terrestrial and have been found in mountainous areas in southern China. Thailand and India.     

Heckerocrinus, a new substitute generic name for fossil crinoid Bockia Hecker 1940 (Echinodermata: Crinoidea) non Reisinger 1924 (Vermes: Turbellaria)

Heckerocrinus nom. nov., a new generic name of fossil Ordovician crinoid, is proposed for preoccupied fossil generic name Bockia Hecker 1940 non Reisinger 1924 [Vermes: Turbellaria??Typhloplanidae-Protoplanellinae]. Illegitimate family name Bockiidae Ubaghs 1972 is replaced with a new valid family name Heckerocrinidae nom. nov.     

New substitute name for the genus Poliocoris Slater, 1994 (Hemiptera,Heteroptera, Rhyparochromidae)

Neopoliocoris nom. n., a new substitute name is proposed for Poliocoris Slater, 1994 (Hemiptera: Heteroptera: Rhyparochromidae), preoccupied by Poliocoris Kirkaldy, 1910 (Hemiptera: Heteroptera: Pentatomidae). A new combination, Neopoliocoris umbrosus (Slater, 1994), comb. n. is proposed for Poliocoris umbrosus Slater, 1994.     

Plasmanate: a new plasma substitute for pediatric therapy

Plasmanate(R), a human-serum protein solution, appears to have all the attributes of an ideal plasma expander. Freedom from infection, immediate availability in a clear, stable solution and the apparent absence of antigenic properties are particularly valuable qualities. The efficacy and safety of Plasmanate was clinically demonstrated in the treatment of 125 infants and children. This solution seems especially effective in the treatment of acute shock states and for the physiologic correction of hypoproteinemia. Comparison with other plasma expanders makes Plasmanate the agent of choice in the initial treatment of shock states in pediatrics.     

PNAD-CSS: a workbench for constructing a protein name abbreviation dictionary

MOTIVATION: Since their initial development, integration and construction of databases for molecular-level data have progressed. Though biological molecules are related to each other and form a complex system, the information is stored in the vast archives of the literature or in diverse databases. There is no unified naming convention for biological object, and biological terms may be ambiguous or polysemic. This makes the integration and interaction of databases difficult. In order to eliminate these problems, machine-readable natural language resources appear to be quite promising. We have developed a workbench for protein name abbreviation dictionary (PNAD) building. RESULTS: We have developed PNAD Construction Support System (PNAD-CSS), which offers various convenient facilities to decrease the construction costs of a protein name abbreviation dictionary of which entries are collected from abstracts in biomedical papers. The system allows the users to concentrate on higher level interpretation by removing some troublesome tasks, e.g. management of abstracts, extracting protein names and their abbreviations, and so on. To extract a pair of protein names and abbreviations, we have developed a hybrid system composed of the PROPER System and the PNAD System. The PNAD System can extract the pairs from parenthetical-paraphrases involved in protein names, the PROPER System identified these paris, with 98.95% precision, 95.56% recall and 97.58% complete precision. AVAILABILITY: PROPER System is freely available from http://www.hgc.inc.u-tokyo.ac.jp/service/tooldoc /KeX/intro.html. The other software are also available on request. Contact the authors.

Enemy-free space: a new name for an ancient ecological concept

While the importance of enemy-free space in structuring animal communities well merits the attention recently given to it, the concept is far more ancient than has been suggested. Far from Charles Darwin being "the first to argue this", as recently claimed, it has long been known that "major aspects of species' lifestyles are moulded by the impact of natural enemies". Examples from the literature spanning a period of more than two millenia, some of them far more specific than Darwin's comment, are cited.
