    AUSTRALIAN NATIVE PLANTS SOCIETY (Australia) Jnc. EPACRIS STUDY GROUP Group Leader: Gwen Elliot, P.O.Box 655 Heathmont Vic. 3135 NEWSLETTER NO. 30 (ISSN 1038-6017) Greetings to all Epacris Study Group members, Regular readers of our Newsletters will have noticed the following note which was added to page 1 of our Autumn 2010 issue, just prior to it going to press. NOTE: I have just received in the post an envelope addressed to the Epacris Study Group, posted from Hobart on May Znd, 2010. Unfortunately the envelope was slit along the bottom and was totally empty. There was no information regarding the sender, but ifyou have sent such a letter in recent days, please let me know, and perhaps cancel any cheque sent. Fortunately all turned out well in the end, as the next morning an Epacris Study Group renewal form was delivered with a $5 note stapled to the corner. Our very nice Post Office manager advised that it had been found on the floor of the district sorting office. He went on to explain that many of today's envelopes have a very effective self-sealing strip and if there is any air left in the envelope when the seal is fastened envelopes can 'pop' at the bottom as they go through the rollers of the sorting machines. This is certainly something I had not personally considered previously, but I felt it is very useful information for us all to be aware of. All of my letters will be squashed down firmly in future to avoid this potential problem.

  • Budawangia* an E-Newsletter for All Those Interested in the Native Plants of the Nsw South Coast
    BUDAWANGIA* AN E-NEWSLETTER FOR ALL THOSE INTERESTED IN THE NATIVE PLANTS OF THE NSW SOUTH COAST Contact: Dr Kevin Mills – [email protected] No. 48 - March 2016 Aims: To connect those interested in the native flora of the NSW South Coast, to share up to date information on the flora of the region and to broaden the appreciation of the region’s native plants. Editorial With continuing warmer oceans around Australia, El Nino has deepened during the last two months, and our dry conditions continued into mid-March when some reasonable rain finally came. We can only be thankful that the severe bushfires this season in other states have not occurred in our part of the world. Blackberry bushes were introduced for their fruit but now are regarded as noxious weeds. Many of us would remember going out in summer and collecting the fruit from thickets of Blackberry in paddocks and escarpment clearings. Native raspberries are closely related to the Blackberry, and there are four species in the region, although their fruits are not as an attractive culinary treat as the introduction. The native raspberries are the subject of the first piece in this newsletter, followed by items on a plant of the month, an eatable thistle, slime mould and a new weed for the region. The answers to last month’s challenge to identify rainforest tree bark are also provided as is a photo of a common local frog from a reader. Below is another note on a common Australian genus. Grevillea - named in 1809 after the English politician and founder of the London Horticultural Society Charles Francis Greville.

    Revista IDE@ - SEA, nº 91B (30-06-2015): 1–12. ISSN 2386-7183 1 Ibero Diversidad Entomológica @ccesible www.sea-entomologia.org/IDE@ Class: Maxillopoda: Copepoda Order HARPACTICOIDA Manual Versión española CLASS MAXILLOPODA: SUBCLASS COPEPODA: Order Harpacticoida Maria José Caramujo CE3C – Centre for Ecology, Evolution and Environmental Changes, Faculdade de Ciências, Universidade de Lisboa, 1749-016 Lisboa, Portugal. [email protected] 1. Brief definition of the group and main diagnosing characters The Harpacticoida is one of the orders of the subclass Copepoda, and includes mainly free-living epibenthic aquatic organisms, although many species have successfully exploited other habitats, including semi-terrestial habitats and have established symbiotic relationships with other metazoans. Harpacticoids have a size range between 0.2 and 2.5 mm and have a podoplean morphology. This morphology is char- acterized by a body formed by several articulated segments, metameres or somites that form two separate regions; the anterior prosome and the posterior urosome. The division between the urosome and prosome may be present as a constriction in the more cylindric shaped harpacticoid families (e.g. Ectinosomatidae) or may be very pronounced in other familes (e.g. Tisbidae). The adults retain the central eye of the larval stages, with the exception of some underground species that lack visual organs. The harpacticoids have shorter first antennae, and relatively wider urosome than the copepods from other orders. The basic body plan of harpacticoids is more adapted to life in the benthic environment than in the pelagic environment i.e. they are more vermiform in shape than other copepods. Harpacticoida is a very diverse group of copepods both in terms of morphological diversity and in the species-richness of some of the families.

Threats of them endemic to Tasmania and many to invertebrates include loss of habitat, with very limited distribution. In all 121 species impact of livestock, changes to hydrology of invertebrate (Worms, Spiders, Crustacea, and invasive pests such as the European Butterflies and Moths, Caddisflies, Beetles, wasp put Tasmania’s butterflies at risk. Tasmania has 15 species of burrowing crayfish between the far northeast coast and south of Macquarie Harbour in the west inhabiting swampy areas and along streams. A few of these species FACT SHEET have large distributions and are quite adaptable, while others such as the threatened Burnie burrowing crayfish and Central North burrowing crayfish have very restricted distributions. These threatened species are at risk from loss of habitat, impact of livestock, changes to hydrology and water pollution. Maintaining a good fenced native vegetation buffer between cropping and pasture land and waterways reduces pollution andsedimentation within the waterway as well as protecting the Burnie borrowing crayfish riparian zone and burrowing crayfish from Image: Joanna Lyall trampling by livestock. The largest freshwater invertebrate in the world (potentially growing to 6kg), the very slow growing Giant freshwater lobster is another of our threatened species in the Cradle Coast region. It is threatened by loss of habitat through farming and forestry activities that cause siltation, disturbance of river banks and streamside vegetation, water temperature changes and removal of in-stream woody debris.
