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. -
Transmission of Bee-Like Vibrations in Buzz-Pollinated Plants with Different
www.nature.com/scientificreports OPEN Transmission of bee‑like vibrations in buzz‑pollinated plants with diferent stamen architectures Lucy Nevard1*, Avery L. Russell2, Karl Foord3 & Mario Vallejo‑Marín1 In buzz‑pollinated plants, bees apply thoracic vibrations to the fower, causing pollen release from anthers, often through apical pores. Bees grasp one or more anthers with their mandibles, and vibrations are transmitted to this focal anther(s), adjacent anthers, and the whole fower. Pollen release depends on anther vibration, and thus it should be afected by vibration transmission through fowers with distinct morphologies, as found among buzz‑pollinated taxa. We compare vibration transmission between focal and non‑focal anthers in four species with contrasting stamen architectures: Cyclamen persicum, Exacum afne, Solanum dulcamara and S. houstonii. We used a mechanical transducer to apply bee‑like vibrations to focal anthers, measuring the vibration frequency and displacement amplitude at focal and non‑focal anther tips simultaneously using high‑speed video analysis (6000 frames per second). In fowers in which anthers are tightly arranged (C. persicum and S. dulcamara), vibrations in focal and non‑focal anthers are indistinguishable in both frequency and displacement amplitude. In contrast, fowers with loosely arranged anthers (E. afne) including those with diferentiated stamens (heterantherous S. houstonii), show the same frequency but higher displacement amplitude in non‑focal anthers compared to focal anthers. We suggest that stamen architecture modulates vibration transmission, potentially afecting pollen release and bee behaviour. Insects use substrate-borne vibrations in a range of ecological contexts, including conspecifc communication and the detection of prey and predators1,2. Tese vibrations are ofen produced and detected on plant material, and the physical properties of the plant substrate, such as stem stifness or leaf thickness, ofen afect vibration propagation3–5. -

Post-Fire Recovery of Woody Plants in the New England Tableland Bioregion
Post-fire recovery of woody plants in the New England Tableland Bioregion Peter J. ClarkeA, Kirsten J. E. Knox, Monica L. Campbell and Lachlan M. Copeland Botany, School of Environmental and Rural Sciences, University of New England, Armidale, NSW 2351, AUSTRALIA. ACorresponding author; email: [email protected] Abstract: The resprouting response of plant species to fire is a key life history trait that has profound effects on post-fire population dynamics and community composition. This study documents the post-fire response (resprouting and maturation times) of woody species in six contrasting formations in the New England Tableland Bioregion of eastern Australia. Rainforest had the highest proportion of resprouting woody taxa and rocky outcrops had the lowest. Surprisingly, no significant difference in the median maturation length was found among habitats, but the communities varied in the range of maturation times. Within these communities, seedlings of species killed by fire, mature faster than seedlings of species that resprout. The slowest maturing species were those that have canopy held seed banks and were killed by fire, and these were used as indicator species to examine fire immaturity risk. Finally, we examine whether current fire management immaturity thresholds appear to be appropriate for these communities and find they need to be amended. Cunninghamia (2009) 11(2): 221–239 Introduction Maturation times of new recruits for those plants killed by fire is also a critical biological variable in the context of fire Fire is a pervasive ecological factor that influences the regimes because this time sets the lower limit for fire intervals evolution, distribution and abundance of woody plants that can cause local population decline or extirpation (Keith (Whelan 1995; Bond & van Wilgen 1996; Bradstock et al. -
Fusion Within and Between Whorls of Floral Organs in Galipeinae (Rutaceae): Structural Features and Evolutionary Implications
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2013 Fusion within and between whorls of floral organs in Galipeinae (Rutaceae): structural features and evolutionary implications El Ottra, Juliana Hanna Leite ; Pirani, José Rubens ; Endress, Peter K Abstract: BACKGROUND AND AIMS: Most genera of the neotropical Galipeinae (tribe Galipeeae, Rutoideae) exhibit several forms and degrees of fusion between the floral organs, including the union of petals into an apparently sympetalous corolla, the joining of the stamens among themselves and to the corolla, and the partial to complete connation of carpels. Though these and others floral traits are cur- rently used in the circumscription of species in Galipeinae, few studies have shown in detail in which way (postgenital or congenital) and to what extent these fusions occur. To elucidate these anatomical condi- tions, a structural study of the flowers of the Galipeinae species was carried out. METHODS: Flowers of six species from three genera of Galipeinae were studied in their morphology, anatomy and development with stereomicroscopy, light microscopy and scanning electron microscopy (SEM). KEY RESULTS: The floral tube is formed by synorganization of stamens with petals in all species, and exhibits threemain patterns: (1) Conchocarpus heterophyllus and C. minutiflorus have a floral tube formed by marginal coherence/adherence of petals and filaments due to interwining trichomes (postgenital connection); (2) Erythrochiton brasiliensis has a tube formed by congenital fusion of petals and filaments; and (3) Gali- pea jasminiflora and Conchocarpus macrophyllus have a tube formed distally with the first pattern, and proximally with the second pattern. -

Duretto2 1 National Herbarium of Victoria, Royal Botanic Gardens Melbourne, Private Bag 2000, South Yarra, VIC, 3141, Australia 2 Tasmanian Herbarium, Tasmanian Museum and Art Gallery, Private Bag 4, Hobart, TAS, 7001, Australia Author for correspondence: [email protected] Abstract Crowea exalata F.Muell. was sampled throughout its morphological and geographical range to test the validity of the current circumscription of the species and subspecies. Through numerical analysis of morphological and chemical (leaf flavonoids and volatile oils) data four taxa are recognised, subsp. exalata, subsp. revoluta Paul G.Wilson, subsp. magnifolia Gebert subsp. nov. and subsp. obcordata Gebert subsp. nov. Descriptions and a key to all taxa are provided. Introduction Crowea Sm. (Rutaceae) is an Australian genus of three species that was first described by J.E. Smith and named in honour of James Crowe esq. F.L.S. (Smith 1798, 1808). Smith, however, was not one to give specific epithets to species of monotypic genera, and in the case of Crowea this was done by Andrews (1800) when he described C. saligna Andrews (see Wilson 1970). Members of Crowea are multi-stemmed, erect, evergreen, woody perennials to 2 m tall with white to rose pink, solitary, axillary flowers. Probably the closest relative to Crowea is Eriostemon Sm. (Bayly et al. 1998; Wilson 1998). Eriostemon contains two species, E. australasius Pers. and E. banksii A.Cunn. ex Endl. Eriostemon australasius is often found in sympatry with C. -
