One of the Oregon Biodiversity Information Center's main tasks is to list and rank rare, threatened, and endangered species in Oregon. Using our Biotics biodiversity database of species occurrences throughout the state and by consulting with agencies, specialists, academics, and the public, ORBIC reviews and publishes this list every two to three years. Eucephalus gormanii × Eucephalus ledophyllus is a rare F1 hybrid encountered in the Cascade Mts. of Oregon. The hybrid is morphologically intermediate between the two parental species E. gormanii and E. ledophyllus and has pink rays. Eucephalus, a relatively well-marked western North American group, has been treated as a section of Aster or as a distinct genus. Recent molecular evidence places Eucephalus, together with the eastern North American Doellingeria, at the base of the North American clade of Astereae. 2. Eucephalus elegans Nuttall, Trans. Amer.

Migration Patterns of lstiophoridae in the Pacific Ocean as Determined by Cooperative Tagging Programs JAMES L. SQUIRE, JR.' ABSTRACT Since , billfish have been tagged by cooperative marine game fish tagging programs in many of the major sportfishing areas of the Pacific. Major locations of tagging have been off southern California, U.S.A., Baja California Sur and mainland Mexico, Panama.

  Apristurus platyrhynchus and four related species were reviewed taxonomically.A. sibogae from Indonesia andA. micropterygeus from the South China Sea were valid species.A. verweyi from the Philippines andA. acanutus from the South China Sea were junior synonyms ofA. platyrhynchus. A. platyrhynchus was re-described, and its new biological information was by: 5. Giant clams (genus Tridacna) are iconic coral reef animals of the Indian and Pacific Oceans, easily recognizable by their massive shells and vibrantly colored mantle Tridacna species are listed by CITES and the IUCN Redlist, as their populations have been extensively harvested and depleted in many regions. Here, we survey Tridacna crocea and Tridacna maxima from the eastern Indian Cited by: Taxonomic characters to identify Orius species (Heteroptera: Anthocoridae) are pronotum (presence of setae in corners, shape of callus), ostiolar peritreme (although more useful at generic level. Synergus complex of species support the monophyly of the large genus Synergus and the smaller Synophrus, while the monophyly of Saphonecrus was rejected. These results are also supported by the new molecular phylogeny which we propose in this thesis. Objective of studies.
