New and interesting Laboulbeniales parasitic on Brazilian Diptera

Three new Laboulbeniales occurring on Brazilian Diptera are described. These are Stigmatomyces cearensis, parasitic on Guttipsilopa (Nesopsilopa) stonei (Mathis & Wirth) (Ephydridae); Stigmatmyces gratiellae, parasitic on Cressonomyia meridionalis (Cresson) (Ephydridae); and Stigmatomyces litoralis, parasitic on Glenanthe caribea Mathis and Paraglenanthe bahamensis Wirth (both Ephydridae). Fifteen other dipterophilous Laboulbeniales are reported for the first time from Brazil. The synonomy between Stigmatomyces notiphilae Thaxt. and S. leucophengae Thaxt. also is proposed.

Hystrignathus ferox n.sp. and Xyo xiphacanthus n.sp. (Oxyurida: Hystrignathidae) with additional data on Carlosia tijucana Travassos & Kloss, 1957

Summary Two new species of hystrignathid nematode are described from passalid beetles in Trinidad, West Indies. Hystrignathus ferox n.sp., from the mid-gut caeca of Verres furcilabris (Esch.) is easily differentiated from H. rugosus Travassos & Kloss, 1958 and H. rescens Travassos & Kloss, 1958 on the character of the lateral alae. In H. rugosus the alae extend to the anus and in H. rescens to the vulva whereas in H. ferox n.sp. the alae are much shorter and terminate about two body-widths anterior to the vulva. Xyo xiphacanthus n.sp., from the mid-gut caeca of Veturius transversus var. trituberculatus (Esch.), is characterized by the cervical spines extending about an oesophagus length posterior to the basal bulb. No other nominal species of Xyo has the spines extending so far posteriorly. X. histrix Cobb, 1898 and X. histrix sensu Christie, 1934 are regarded as species inquirendae. Carlosia tijucana Travassos & Kloss, 1957 is illustrated and additional data provided. ac]19810415     

Soil texture as an influence on the distribution of the desert seed-harvester ants Pogonomyrmex rugosus and Messor pergandei

Summary Pogonomyrmex rugosus and Messor pergandei are ecologically similar species of desert seed-harvester ants that coexist in numerous areas throughout the Sonoran and Mohave Deserts. However, these two species also commonly segregate along physical gradients, with each species predominating in areas that differ in soil texture and/or topographic relief. Along gradients that included bajada and alluvial flat habitats, P. rugosus occurred alone in coarse-textured soils near mountains, while M. pergandei occurred alone in finer-textured soils further away. Conversely, along a vegetation gradient that included creosote bush and saltbush habitats, P. rugosus occurred alone in finer-textured soils than those occupied by either M. pergandei alone or both species in coexistence. However, in both situations clay content was significantly higher in areas occupied by P. rugosus alone, and at the latter site clay content was correlated with relative abundance of each species. Moreover, local distribution pattern of these two species may be related to the effects of clay on water retention, with retention being highest in areas occupied by P. rugosus alone. Differences in reproductive ecology may also affect these patterns as P. rugosus reproductive flights follow summer monsoon rains, while those of M. pergandei occur during the milder winter and spring.

New species, observations, and a list of new records of brown algae (Phaeophyceae) from the Hawaiian Islands

Two new species of brown algae (Phaeophyceae), Padina moffittiana Abbott et Huisman, sp. nov. and Cutleria irregularis Abbott et Huisman, sp. nov., are described from the Hawaiian Islands (between 19°04′N, 155°35′W and 28°25′N, 178°20′W). In addition, the new combination Cutleria canariensis is proposed for Aglaozonia canariensis. New observations are presented on Nereia intricata Yamada, a species described 67 years ago and known only from its type specimen. New records of a further 14 species are given for the Hawaiian Islands. These 17 taxa bring the total number of species of brown algae recorded for the Hawaiian Islands to 55, an increase of 28%. Of the 15 new records, two are recent ‘accidental’ introductions: Dictyota flabellata (Collins) Setchell et Gardner and Sargassum muticum (Yendo) Fensholt from California. Six records are notable because of their great distances from previously known collections: Nereia intricata Yamada from the Ryukyu Is., Japan; Discosporangium mesarthrocarpum (Meneghini) Hauck, from the Adriatic, Mediterranean, warm Atlantic and southern Australia; Distromium flabellatum Womersley, Spatoglossum macrodontum J. Agardh, and Sporochnus moorei Harvey, from Australia; Desmarestia ligulata (Lightfoot) Lamouroux from temperate and colder waters in the Pacific and Atlantic. A comparison with some Japanese species of Padina confirms that Padina japonica Yamada should be subsumed with Padina sanctae‐crucis Børgesen, as proposed earlier.

Tre nuove specie di Stigmatomyces (Ascomycetes,Laboulbeniales) parassite di Ditteri italiani

Abstract

New species of Stigmatomyces (Ascomycetes, Laboulbeniales) parasitic on Italian Diptera. – Three new Laboulbeniales parasitic on Italian Diptera are described: Stigmatomyces asteiae, parasitic on Asteia amoena Meig. (Asteiidae), Stigmatomyces athyroglossae, parasitic on Athyroglossa glabra (Meig.) (Ephydridae), and Stigmatomyces geomyzae, parasitic on Geomyza tripunctata Fall. (Opomyzidae).     

TWO NEW AUSTRALIAN SPECIES OF PREDAEA (NEMASTOMATACEAE,RHODOPHYTA) WITH TAXONOMIC RECOMMENDATIONS FOR AN EMENDED NEMASTOMATALES AND EXPANDED HALYMENIALES1

Two new species of the red algal genus Predaea are described from Australia. The first, Predaea aurora Kraft et G.W. Saunders, sp. nov., is unusual in its cool‐temperate distribution and in a number of anatomical attributes, most notably the rhizoid‐like habit of the nutritive filaments associated with the auxiliary cells. The second species, Predaea tumescens Kraft et G.W. Saunders, sp. nov., inhabits a coral reef habitat more typical of the genus but nonetheless differs in a number of anatomical details from other reported species. Nuclear small subunit rDNA sequences have confirmed the affinity of P. aurora to other species currently included in this genus. Molecular analyses further indicate that Predaea belongs in the Nemastomataceae and that the Nemastomataceae and Schizymeniaceae are sister taxa in an independent clade of “lineage 4” florideophyte algae. As such, a proposal is made to resurrect the Nemastomatales Kylin emend. G.W. Saunders et Kraft to accommodate these two families. Within the Schizymeniaceae, the Australian‐endemic Platoma australicum and Platoma foliosum were only distantly related to the other included Platoma, Schizymenia, and Titanophora spp. We therefore propose Wetherbeella G.W. Saunders et Kraft, gen. nov., to accommodate these two species. An additional outcome of our molecular analyses is that the genus Tsengia is not a member of the Nemastomataceae (where it is currently placed) but rather forms an independent lineage in the Halymeniales that we now designate as the Tsengiaceae G.W. Saunders et Kraft, fam. nov. Finally, the South African Nemastoma lanceolatum J. Agardh is transferred to Tsengia.     

The content of protein,fibre and minerals of leaves of selected Acacia species indigenous to north-western Tanzania

Abstract

Browse tree leaves of six species of Acacia (A. angustissima L., A. drepanolobium L., A. nilotica L., A. polyacantha L., A. senegal L., A. tortilis L.) were screened for chemical composition, including minerals and trace elements. Crude protein (CP) varied among the species from 145 (A. senegal) to 229 g/kg DM (A. angustissima). The species had moderate to high levels of minerals. The concentrations of Ca, P, Mg and S varied among the species from 14.6 – 31.5, 3.5 – 4.9, 1.4 – 3.0 and 1.7 – 2.8 g/kg DM, respectively. The forages showed relatively low concentrations of trace elements. Content of trace elements varied among the species from 4.5 – 23.8, 99.4 – 173.6, 146.2 – 432, 41.0 – 90.1, 10.9 – 22.2 and 0.05 – 0.65 mg/kg DM for Cu, Mo, Fe, Mn, Zn and Co, respectively. All leaves of browse species would meet the normal requirements for Ca, P, Mg and S in ruminants, although some species had higher levels of Ca than tabulated mineral requirements in livestock. Assayed Cu, Mn, Zn and Co would satisfy the lower range of recommended requirements of trace elements depending on their bioavailability. Therefore, browse leaves from Acacias could form good sources of CP and mineral supplements to ruminants.     

MOLECULAR DIVERSITY OF MARINE PHYTOPLANKTON COMMUNITIES BASED ON KEY FUNCTIONAL GENES1

The phylogeny and diversity of two key functional genes were investigated as the basis for improved understanding of the community structure of natural phytoplankton assemblages in marine environments. New partial NR (encoding eukaryotic assimilatory nitrate reductase) and rbcL (encoding LSU of RUBISCO) sequences from 10 cultured phytoplankton strains are reported. Phytoplankton community composition from Monterey Bay (MB), a coastal upwelling site on the California coast, and the Western English Channel (EC), a North Atlantic spring bloom environment, was elucidated based on NR and rbcL sequences. Diatoms were by far the most frequently detected group in both environments, consistent with their importance as a major bloom‐forming group. Both NR and rbcL libraries contained sequences representing cosmopolitan types such as Emiliania huxleyi (Lohmann) W. W. Hay et H. P. Mohler, Phaeocystis, and Pseudo‐nitzschia. The NR and rbcL libraries also contained sequences from other chromophytic algal groups and the Dinophyceae (alveolates). Sequences showing identity with key bloom‐forming organisms including E. huxleyi, Phaeocystis pouchetii (Har.) Lagerh., Pseudo‐nitzschia sp., and Thalassiosira sp. in the rbcL libraries confirm previous studies from these environments based on traditional approaches. Diversity/pattern analyses detected significant compositional differences among the libraries, which were consistent with patterns identified by phylogenetic analysis, but these patterns were not strongly correlated with obvious environmental variables such as temperature and nitrate concentration. Many new and divergent NR and rbcL sequences are reported, but the extent to which they represent unknown types cannot be determined until greater effort is made to sequence the existing culture collections.     

SOME PIECES OF THE AFRICAN GENOME PUZZLE IN HIBISCUS SECT. FURCARIA (MALVACEAE)

New chromosome counts are reported for four African diploid species of Hibiscus L. sect. Furcaria DC: H. greenwayi Bak. f., H. hiernianus Exell et Mendonça, and H. mechowii Garcke, n = 18; and H. berberidifolius A. Rich., 2n = 36. Chromosome behavior is described in seven new hybrid combinations. Hibiscus greenwayi is shown to carry an A genome. Hibiscus hiernianus and H. mastersianus have similar genomes which are not homologous with that of H. mechowii. New and earlier data are integrated to elucidate genome relationships among 13 taxa–each of the four tetraploid species has a different formula encompassing 2 of 6 mutually nonhomologous genomes, A, B, G, H, X and Y (H. acetosella Welw. ex Hiern = AABB; H. meeusei Exell = AAXX; H. sabdariffa L. = AAYY; H. rostellatus Guill. et Perr. = GGHH). Diploid donors of A, B, G, X and Y are proposed on the basis of plant, flower and pollen morphology. Diploid carriers of A (H. asper Hook. f., H. cannabinus L., H. greenwayi), B (H. surattensis L.) and G (H. sudanensis Hochr.) have been verified cytologically. Cytological confirmation of X (H. hiernianus, H. mastersianus Hiern) and Y (H. mechowii) carriers is incomplete. No putative diploid carrier of H is at hand. Genome affinities of H. berberidifolius are unknown.
