In the years 1969-1970 the parasitie mycoflora of plants occurring in the littoral of 51 lakes of the Olsztyn and Mrągowo lake distriets and inthe Land of Great Lakes was examined. 132 species of parasitic fungi on the 150 vascular plants species were found, 6 of them for the first time in Poland, and 9 on hosts hitherto not observed in Poland. The influence of ecological factors such as the zone of the littoral, the position and irradiation of the coast etc. on the occurrence of pathogens was noted. The effect of some pathogenes on the transpiration, level of nitrogen and phosphorus, calorific value and yield of host plants wasalso examined, maily for <i>Phragmites communis</i> Trin.

The paper contains a list of 312 species of fungi which are parasites of vascular plants in areas which are now in the Piła and Bydgoszcz voivodships. They were collected by the author (who died in 1973) in the years 1968-1973. <i>Tilletia holci</i> and <i>Puccinia littoralis</i> were reported for the first time in Poland and several species were observed on host previously not noted in Poland.

Two uncommon species, Hydrellia tarsata Haliday and H. flaviceps Meigen, are recorded for the first time from Russia and from its north-western part, respectively. Larval habitats, host plants (Stratiotes aloides L.) and braconid parasitoids of both the species are indicated for the first time. H. tarsata is shown to develop abundantly within the lake littoral zone. The braconid Chaenusa opaca Stelfox is recorded from Russia for the first time.

The article presents data about 14 species of smut fungi that occur in the Nurata ridge. During analyzes confinement them to host plants revealed that they parasitize on 16 species of vascular plants belonging to 5 families. On family Poaceae was observed 10 species of smut fungi that constitute 71.4 % of the total of smuts of Nurata. 14 species of smut fungi observed in seasonal distribution were studied. Among them 2 species (Vankya heufleri, Antracoidea eleocharidis) found in the spring, only 1 species (Ustilago cyno-dontis) in spring-autumn period. Also smut fungi first time found on host plants of Carex stenophylla, Tulipa turkestanica, Thalictrum sultanabadense, Stipa capillata and Stipa lipskyi in Uzbekistan. Refs 7. Figs 5. Tables 3.

AbstractThis communication gives an overview of the relationships between four reactions that although related were not always perceived as such: SN2, Walden, Finkelstein, and Menshutkin. Binary interactions (SN2 & Walden, SN2 & Menshutkin, SN2 & Finkelstein, Walden & Menshutkin, Walden & Finkelstein, Menshutkin & Finkelstein) were reported. Carbon, silicon, nitrogen, and phosphorus as central atoms and fluorides, chlorides, bromides, and iodides as lateral atoms were considered. Theoretical calculations provide Gibbs free energies that were analyzed with linear models to obtain the halide contributions. The M06-2x DFT computational method and the 6-311++G(d,p) basis set have been used for all atoms except for iodine where the effective core potential def2-TZVP basis set was used. Concerning the central atom pairs, carbon/silicon vs. nitrogen/phosphorus, we reported here for the first time that the effect of valence expansion was known for Si but not for P. Concerning the lateral halogen atoms, some empirical models including the interaction between F and I as entering and leaving groups explain the Gibbs free energies.

New collections of vascular plants, bryophytes, lichen, and algae are reported for Cunningham Inlet on the north coast of Somerset Island, Nunavut. This list of 48 species of vascular plants, 13 bryophytes, 10 lichens, and five algae includes 136 specimens collected in 2013 and 39 previously unreported specimens from the National Herbarium of Canada at the Canadian Museum of Nature (CAN), Agriculture and Agri-Food Canada’s Vascular Plant Herbarium (DAO), and University of Alberta (ALTA). Ten vascular plants from previous collecting in 1958 are re-reported here to give a comprehensive account of the vascular plant flora of the region. Two vascular plants are recorded for the first time for Somerset Island: Smooth Draba (Draba glabella Pursh) and Edlund’s Fescue (Festuca edlundiae S. G. Aiken, Consaul & Lefkovitch).

The paper treats fifteen species of leaf-mining pygmy moths (Insecta, Lepidoptera, Nepticulidae) discovered in the Neotropics (British Virgin Islands, Belize, Costa Rica, Venezuela, and Ecuador), and Ando-Patagonian region (Argentina and Chile). Except for two species, all belong to Stigmella Schrank. Twelve species are new, and are named and described in the current paper: Stigmella apicibrunella Diškus & Stonis, sp. nov.; S. decora Diškus & Stonis, sp. nov.; S. unicaudata Remeikis & Stonis, sp. nov.; S. sanmartini Remeikis & Stonis, sp. nov.; S. patula Remeikis & Stonis, sp. nov.; S. torosa Remeikis & Stonis, sp. nov.; S. monstrata Remeikis & Stonis, sp. nov.; S. huahumi Remeikis & Stonis, sp. nov.; S. venezuelica Remeikis & Stonis, sp. nov.; S. virginica Remeikis & Stonis, sp. nov.; Fomoria miranda Diškus & Stonis, sp. nov.; and Hesperolyra robinsoni Stonis, sp. n. Newly discovered variation of male genitalia of the Andean Stigmella rudis Puplesis & Robinson, 2000 is briefly discussed, and the formerly poorly understood Stigmella hylomaga (Meyrick, 1931) is redescribed and documented with photographs for the first time. We also present more photographs and add some addtional information on Stigmella gallicola van Nieukerken & Nishida, a recently described gall-maker from Costa Rica.The paper also provides new host-plant data: some of the described (or redescribed) species are reported for the first time as leaf-miners on plants belonging to Euphorbiaceae (Acalypha padifolia Kunth), Salicaceae (Azara microphylla Hook. f.), Fabaceae (Inga spectabilis (Vahl) Willd. or I. edulis Mart.), Rhamnaceae (Colletia spinosissima J. F. Gmel.), Geraniaceae or Vivianiaceae (Rhynchotheca spinosa Ruiz & Pav.), and Asteraceae (Mutisia decurrens Cav.). All species treated in the paper are illustrated with photographs of the adults and genitalia, a distribution map, and also photographs of the leaf-mines and host plants when available.

The ecological factors controlling the distribution and abundance of the folivorous marsupials endemic to the rainforests of northern Australia are not understood. In this study, we surveyed folivore abundance at 40 sites stratified by altitude and geology in rainforests of the Atherton Tableland, north Queensland. All five species of folivore that inhabit the study area were more abundant in highland (800–1200 m) than in upland (400–800 m) forests. Allowing for the effects of altitude, four species of folivore were more abundant in forests on nutrient-rich basalts than in forests on nutrient-poor acid igneous or metamorphic rocks. The abundance of two folivore species also varied inversely with rainfall. Altitudinal variation in folivore abundance in the study area has been attributed to habitat destruction, Aboriginal hunting, the distribution of host plants and climate; however, none of these hypotheses has been tested. Variation in folivore abundance with geology is plausibly explained as a response to the nutritional quality of foliage. Foliage quality may also explain the inverse relationship between two of the folivores and rainfall. The results of this study show that only a relatively small proportion of north Queensland rainforests support abundant populations of the endemic folivorous marsupials.

Abstract New records of 110 species of the acalyptrate Diptera family Agromyzidae are given from Portugal, including Madeira, Porto Santo and the Azores. A quarantine plant pest, Nemorimyza maculosa (Malloch, 1913), was detected in the Old World for the first time. Details on Phytobia xylem- miners and a parthenogenetic Phytomyza species are recorded together with new distribution data. For certain species morphological and taxonomic notes and discussions on known or new host plants are added. A complete checklist of Agromyzidae of Portugal is presented.
