PRO NATURA NOVARA ONLUS GRUPPO MALACOLOGICO NOVARESE (Gianfranco Vischi)
PRO NATURA NOVARA ONLUS GRUPPO MALACOLOGICO NOVARESE (Gianfranco Vischi) ([email protected]) n. 23 agosto 2015 La UMBILIA Armeniaca di R. Paolo Cesana Nella vasta famiglia delle Cypree, spiccano tra le ''medio-grandi'' forme australiane, quelle appartenenti alla ''tribù'' delle umbiliinae; consideriamo quindi il genere Umbilia armeniaca con le sue forme e/o sottospeci. La Umbilia armeniaca armeniaca (Verco, J. C. 1912) è la specie base, che vive sui fondali molli, in prevalenza tra le alghe, in acque profonde, sempre al di sotto dei 25 m. E' specie del sud e sud-vest dell'Australia, che va da Perth ad Adelaide. L'animale ha, sembra, una dieta mista, un po’ detritivora (detriti e residui) e un po’ spongivora. La sua conchiglia è simile a quella della sua cugina hesitata, ma più enflata e leggera, con la parte anteriore meno ''affusolata''. La fossula è più marcata, poco depressa; la dentatura è poco evidente e assente verso la estremità posteriore sul lato columellare, ben marcata invece nella parte anteriore; l'apertura è molto curvata verso l'estremità posteriore. La colorazione varia dal raro bianco al rosa salmone (tipico) con lievi maculature dorsali e sui lati, la base è sul beige-rosato o aranciato con un'rea più colorata dal lato columellare. La conchiglia ha una misura che varia tra i 65 e i 120 mm. circa. Passiamo ora alle poche sottospeci o ''forme'' che per le lievi differenze che si possono riscontrare fra loro, farò una breve carrellata di esse; - la Umbilia armeniaca westralica (Raibaudi Massilia, 1980) globosa, ha forma e caratteristica simile alle altre armeniache, la colorazione lucida varia dal bianco-giallastro al salmone rosato, al bruno, con sparse maculazioni varie sul dorso e i lati; come dice il suo nome, vive a sud ovest dell'Australia, la conchiglia è lunga circa 70 - 100 mm. -

Bossiaea Ensata
Bossiaea ensata Family: Fabaceae subfamily Faboideae Distribution: Woodland and open forest in south-east Queensland, eastern New South Wales and north-east Victoria. Common Sword bossiaea. Name: Derivation of Bossiaea... After Boissieu de la Martinière, a physician Name: and plant collector who participated in the expedition of Jean-Francois de La Perouse in 1785. ensata... From Latin ensatus, sword-like, referring to the flattened stems of this species. Conservation Not considered to be at risk in the wild. Status: General Description: Bossiaea is a genus of about 50 species all of which occur naturally only in Australia. They are found in all States and are small to medium shrubs. Bossiaea ensata Photo: Brian Walters Bossiaea ensata is a small shrub, often with a low, spreading habit and only rarely reaching about 1 metre high. It is generally leafless and has flattened, winged stems whose function takes the place of leaves (the leaves are actually reduced to small scales along the flattened stems). The stems are usually 3 to 10 mm in width (which distinguishes B.ensata from the similar B.scolopendria, which has winged stems up to 15 mm wide). True leaves are sometimes seen near the base of the plant or on juvenile stems - these true leaves are small and oval shaped. The flowers are yellow with a red centre and have the typical "pea" shape consisting of 4 petals; the "standard", the "keel" and two "wings", as shown in the diagram. They occur in the leaf "scales" in late spring and summer and are about 10-15 mm long. -
Comparative Floral Presentation and Bee-Pollination in Two Sprengelia Species (Ericaceae)
Comparative floral presentation and bee-pollination in two Sprengelia species (Ericaceae) Karen A. Johnson* and Peter B. McQuillan School of Geography and Environmental Studies, University of Tasmania, Private Bag 78, Hobart, Tasmania 7001, Australia. *Corresponding author. E-mail: [email protected] Abstract: Pollination by sonication is unusual in the Styphelioideae, family Ericaceae. Sprengelia incarnata and Sprengelia propinqua have floral characteristics that suggested they might be adapted to buzz pollination.Both species have florally similar nectarless flowers except that the stamens ofSprengelia propinqua spread widely after the flower opens, while those of Sprengelia incarnata cohere in the centre of the flower. To test whether sonication occurs, we observed bee behaviour at the flowers of both plant species, documented potential pollinators, and examined their floral and pollen attributes. We found that Sprengelia incarnata had smaller and drier pollen than Sprengelia propinqua. We found that Sprengelia incarnata was sonicated by native bees in the families Apidae (Exoneura), Halictidae (Lasioglossum) and Colletidae (Leioproctus, Euryglossa). Sprengelia propinqua was also visited by bees from the Apidae (Exoneura) and Halictidae (Lasioglossum), but pollen was collected by scraping. The introduced Apis mellifera (Apidae) foraged at Sprengelia propinqua but ignored Sprengelia incarnata. The two Sprengelia species shared some genera of potential pollinators, but appeared to have diverged enough in their floral and pollen characters to elicit different behaviours from the native and introduced bees. Cunninghamia (2011) 12 (1): 45–51 Introduction species, some Leucopogon species, Richea milliganii (Hook.f.) F.Muell., and Sprengelia incarnata Sm.

Jervis Bay Territory Page 1 of 50 21-Jan-11 Species List for NRM Region (Blank), Jervis Bay Territory
Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect. All species names have been confirmed as valid species names, but it is not possible to confirm all species locations. -

Alternative Translation Initiation Codons for the Plastid Maturase Matk: Unraveling the Pseudogene Misconception in the Orchidaceae Michelle M
Barthet et al. BMC Evolutionary Biology (2015) 15:210 DOI 10.1186/s12862-015-0491-1 RESEARCH ARTICLE Open Access Alternative translation initiation codons for the plastid maturase MatK: unraveling the pseudogene misconception in the Orchidaceae Michelle M. Barthet1,2* , Keenan Moukarzel3, Kayla N. Smith1, Jaimin Patel3 and Khidir W. Hilu3 Abstract Background: The plastid maturase MatK has been implicated as a possible model for the evolutionary “missing link” between prokaryotic and eukaryotic splicing machinery. This evolutionary implication has sparked investigations concerning the function of this unusual maturase. Intron targets of MatK activity suggest that this is an essential enzyme for plastid function. The matK gene, however, is described as a pseudogene in many photosynthetic orchid species due to presence of premature stop codons in translations, and its high rate of nucleotide and amino acid substitution. Results: Sequence analysis of the matK gene from orchids identified an out-of-frame alternative AUG initiation codon upstream from the consensus initiation codon used for translation in other angiosperms. We demonstrate translation from the alternative initiation codon generates a conserved MatK reading frame. We confirm that MatK protein is expressed and functions in sample orchids currently described as having a matK pseudogene using immunodetection and reverse-transcription methods. We demonstrate using phylogenetic analysis that this alternative initiation codon emerged de novo within the Orchidaceae, with several reversal events at the basal lineage and deep in orchid history. Conclusion: These findings suggest a novel evolutionary shift for expression of matK in the Orchidaceae and support the function of MatK as a group II intron maturase in the plastid genome of land plants including the orchids. -
Rare Or Threatened Vascular Plant Species of Wollemi National Park, Central Eastern New South Wales
Rare or threatened vascular plant species of Wollemi National Park, central eastern New South Wales. Stephen A.J. Bell Eastcoast Flora Survey PO Box 216 Kotara Fair, NSW 2289, AUSTRALIA Abstract: Wollemi National Park (c. 32o 20’– 33o 30’S, 150o– 151oE), approximately 100 km north-west of Sydney, conserves over 500 000 ha of the Triassic sandstone environments of the Central Coast and Tablelands of New South Wales, and occupies approximately 25% of the Sydney Basin biogeographical region. 94 taxa of conservation signiicance have been recorded and Wollemi is recognised as an important reservoir of rare and uncommon plant taxa, conserving more than 20% of all listed threatened species for the Central Coast, Central Tablelands and Central Western Slopes botanical divisions. For a land area occupying only 0.05% of these divisions, Wollemi is of paramount importance in regional conservation. Surveys within Wollemi National Park over the last decade have recorded several new populations of signiicant vascular plant species, including some sizeable range extensions. This paper summarises the current status of all rare or threatened taxa, describes habitat and associated species for many of these and proposes IUCN (2001) codes for all, as well as suggesting revisions to current conservation risk codes for some species. For Wollemi National Park 37 species are currently listed as Endangered (15 species) or Vulnerable (22 species) under the New South Wales Threatened Species Conservation Act 1995. An additional 50 species are currently listed as nationally rare under the Briggs and Leigh (1996) classiication, or have been suggested as such by various workers. Seven species are awaiting further taxonomic investigation, including Eucalyptus sp.
