Scattered small stands of Nothofagus truncata occur in the upper Taramakau catchment, Arthur's Pass National Park, beyond the previously assumed range of the species in north Westland. Restricted to older soils on stable north to north-west slopes, the N. truncata stands are surrounded by N. fusca dominated forest and their upper altitudinal limits at 370-500 m border N. fusca-N. menziesii or N...

The morphological and molecular differentiation of the Micrasterias truncata (Corda) ex Bréb species complex was investigated. In total, 17 strains traditionally assigned to M. truncata were isolated from different European localities (Czech Republic, southwest France, Ireland), and obtained from public culture collections. In addition, strains of the morphologically similar species, M. decemde...

The Phora of Costa Rica were reviewed and three species, all belonging to Schmitz's Group III, were recognized: P. americana Schmitz and Wirth, P. truncata new species and P. paramericana new species. Of the three species, P. americana is by far the most abundant, with the other two species being rarely collected. All specimens were collected in the central highlands of the country. The previou...

BACKGROUND Photosynthetic eukaryotes with a secondary plastid of red algal origin (cryptophytes, haptophytes, stramenopiles, dinoflagellates, and apicomplexans) are hypothesized to share a single origin of plastid acquisition according to Chromalveolate hypothesis. Recent phylogenomic analyses suggest that photosynthetic "chromalveolates" form a large clade with inclusion of several non-photosy...

The possible effects of ocean acidification on growth, organic tissue and protein profile in the bryozoan Myriapora truncata (Pallas, 1766) were studied in samples transplanted along a gradient of different pH conditions in an area of natural volcanic CO2 vents at Ischia Island (Tyrrhenian Sea, Italy). Living colonies from normal (mean pH 8.10), intermediate (pH 7.83) and low (pH 7.32) pH sites...

Organochlorine compounds (OC) were determined in Arctic bivalves (Mya truncata, Serripes groenlandicus, Hiatella arctica and Chlamys islandica) from Svalbard with regard to differences in geographic location, species and variations related to their size and age. Higher chlorinated polychlorinated biphenyls (PCB 101-PCB 194), chlordanes and α-hexachlorocyclohexane (α-HCH) were consistently detec...

In the present paper I propose the following taxonomic changes: Anthaxia (Haplanthaxia) bosdaghensis Obenberger, 1938 (= cavazzutii Bílý, 1980 syn. nov.); A. (Anthaxia) ephippiata Redtenbacher, 1850 (= kreuzbergi Richter, 1944 syn. nov.); A. (H.) pleuralis Faimaire, 1883 (= parapleuralis Obenberger, 1929 syn. nov.); A. (H.) scylla Levey, 1985, removal from synonymy (= aprutiana Gerini, 1955 una...
