Crossability relationships between Korean firs Abies koreana , A. nephrolepis and A. holophylla and some other representatives of the genus Abies

Artificial crossing experiments involving 3 Abies species native to Korean peninsula and 5 other representatives of Abies revealed a high hybridological affinity between Abies koreana and A. nephrolepis. Both these species are reproductively isolated from A. holophylla. All the three Korean species were found to exhibit incompatible relationships with the North American species A. concolor. The species A. holophylla and A. koreana differ also in their abilities to intercross with the Mediterranean firs. The former has been successfully crossed with A. nordmanniana, A. alba and A. cilicica exhibiting 19.1–55.3% crossability, whereas the latter produced filled seeds only with A. nordmanniana reaching 46.4% crossability. A considerable differentiation is postulated to exist between the pair of species A. koreana and A. nephrolepis on the one side and A. holophylla on the other side.     

Three new species of <Emphasis Type="Italic">Anthocephalum</Emphasis> Linton, 1890 (Cestoda: Tetraphyllidea) from dasyatid stingrays of the Gulf of California

Three new species of Anthocephalum Linton, 1890 are described from dasyatid stingrays collected in the Gulf of California. Anthocephalum michaeli n. sp. is described from Dasyatis longus (Garman). This species most closely resembles A. alicae Ruhnke, 1994, but differs from this species in proglottid number. A. lukei n. sp. is also described from D. longus. This new species is most similar to A. cairae Ruhnke, 1994, but differs from that species in marginal loculi number and number of proglottids. The third new species, A. currani n. sp., is described from D. brevis (Garman). This species is most similar to A. centrurum (Southwell, 1925) Ruhnke, 1994, but differs from that species in marginal loculi number, number of testes and ovarian length. Phyllobothrium kingae Schmidt, 1978 is also consistent in morphology with species of Anthocephalum and is transferred to this genus, forming the new combination Anthocephalum kingae n. comb. This species most closely resembles A. michaeli n. sp., but differs in testicular shape. This brings the total number of species of Anthocephalum to nine. The transfer of the species Phyllobothrium arctowskii Wojciechowska, 1991, P. georgiense Wojciechowska, 1991, P. rakusai Wojciechowska, 1991 and P. siedleckii Wojciechowska, 1991 to Anthocephalum is not warranted, as these four species lack a posteriorly recurved cirrus-sac and a sinuous vagina, and have vitelline follicles uninterrupted by the ovary. Of the nine known species, all are parasitic in batoid fishes, and six are found in species of Dasyatis Garman. The phylogenetic status of Anthocephalum species in relationship to Rhinebothroides Mayes, Brooks & Thorson, 1981, Pararhineothroides Zamparo, Brooks & Barriga, 1999 and other rhinebothriin taxa is discussed.

Two new species of night monkeys,genus Aotus (Cebidae,platyrrhini): A preliminary report on Aotus taxonomy

The nine allopatric species of Aotus recognized represent two natural groups distinguished by karyotype, color, and pelage patterns. Correlated with these group characters are reported differences in serum proteins and degrees of susceptibility or immunity to experimental infection with malarial parasites. The primitive gray-neck species group of Aotus contains A. brumbacki (new species), A. lemurinus (with subspecies lemurinus and griseimembra), A. trivirgatus, and A. vociferans. The derived red-neck group contains A. nancymai (new species), A. miconax. A. infulatus, and A. azarae (with subspecies azarae and boliviensis). Only the two new species are described but a key to the species and subspecies gives the diagnostic characters of each. The gray-neck group occurs almost entirely north of the Amazon, the red-neck group almost entirely south. The distributional exceptions are enclave populations resulting from river bend cutoffs. Formation of an enclave population of A. nancymai is discussed and available information on the biology of this species is reported.     

Phylogenetic relationships between two rare acacias and their common, widespread relatives in south-western Australia

Knowledge of phylogenetic relationships betweentaxa is particularly valuable for conservationmanagement of threatened taxa in anevolutionarily diverse flora such as that foundin the south-west of Western Australia. Acacia sciophanes and A. lobulata aretwo threatened species that have restricteddistributions at the edge of the range of theirwidespread relatives, A. anfractuosa andA. verricula respectively. The phylogenyof these species pairs was investigated usingRFLP analysis of cpDNA. Both restricted specieswere shown to be phylogenetically distinct.Acacia sciophanes and A. anfractuosaare sister species and display the characteristics of a relatively recent evolutionary lineage. In comparison A. lobulata shows significant divergence from A. verricula and is not closely related to the species group in which A. verricula is placed. Acacia lobulataappears to represent an ancient lineage and ismost likely a relictual species. Acaciaverricula also has characteristics of a moreancient evolutionary lineage than A.sciophanes and A. anfractuosa. Ifpriority setting processes based onphylogenetic principles were to be applied tothese species A. lobulata would have thegreater biodiversity value for conservationmanagement.

Why are there so many species of mining bees (Hymenoptera,Andrenidae)? The possible roles of phenology and Wolbachia incompatibility in maintaining species boundaries in the Andrena proxima-complex

The factors leading to the extraordinary diversity of the bees of the genus Andrena Fabricius, the second most speciose genus among bees, remain largely unknown. To examine the pattern of diversification in this genus, we investigate species boundaries within the controversial Andrena proxima-complex using a dataset of ultra-conserved elements and various species delimitation analyses (admixture analyses, BPP, DAPC). Our results confirm the presence of three separate species in this species group (Andrena proxima (Kirby), A. ampla Warncke and A. alutacea Stöckhert) and suggest very low levels of interspecific gene flow. Andrena proxima and A. alutacea are regularly found in sympatry, suggesting an advanced stage of speciation. By contrast, A. ampla shows a parapatric distribution with both other species. Andrena alutacea harbours a unique strain of Wolbachia Hertig, absent in the other two species, which are infected by the two same strains of Wolbachia. In addition, the three species have distinct phenologies, with A. proxima flying earlier in the season and A. alutacea significantly later; the phenology of A. ampla is intermediate. Our results suggest that Wolbachia-induced incompatibilities and phenological differences maintain species boundaries in this group. The most advanced stage of speciation is observed in the two species showing putatively incompatible strains of Wolbachia and strongly distinct phenologies, A. alutacea and A. proxima. We propose that the smaller differences in phenological differentiation between A. ampla and both other species may explain the observed pattern of parapatric distribution. We discuss how these factors may underlie the high diversification rate observed in other groups of Andrena, a genus characterized by particularly variable and short flying periods.     

Reproductive Ecology and Host Utilization of Four Sympatric Bitterling (Acheilognathinae,Cyprinidae) in a Lowland Reach of the Harai River in Mie,Japan

Bitterling are fishes that use freshwater mussels for oviposition. The reproductive ecology and pattern of mussel utilization of four sympatric species of bitterling, Acheilognathus rhombeus, A. tabira tabira, Tanakia lanceolata, and T. limbata, were investigated in a lowland river with seven sympatric mussel species. Three bitterling species are spring spawners with overlapping spawning seasons. A. rhombeus is an autumn-spawning species and is temporally isolated in its reproduction from the other species. Ovipositor length during oviposition of T. limbata and T. lanceolata was short, while those of A. tabira tabira and A. rhombeus were long. Most T. limbata inhabited near-shore areas, whereas the two other spring-spawning species were distributed across the entire river. All bitterling species used Inversidens brandti, Obovalis omiensis and Inversiunio jokohamensis as spawning hosts, but not the other mussel species available. T. lanceolata, A. tabira tabira and A. rhombeus showed spawning preferences for O. omiensis and I. brandti. However, T. limbata did not show clear preferences for any of the mussel species they used. A. t. tabira showed a significant preference for large I. brandti in offshore areas, while the other spring-spawning bitterling showed a preference for mussels inshore. These results are discussed in the context of reproductive resource partitioning.
