Geographical Speciation Related to Pleistocene Range Shifts in the Western Mediterranean Mountains (Reseda Sect
Martín-Bravo & al. • Pleistocene speciation in Reseda sect. Glaucoreseda TAXON 59 (2) • April 2010: 466–482 SPECIATION Geographical speciation related to Pleistocene range shifts in the western Mediterranean mountains (Reseda sect. Glaucoreseda, Resedaceae) Santiago Martín-Bravo,1 Virginia Valcárcel,1 Pablo Vargas2 & Modesto Luceño1 1 Department of Molecular Biology and Biochemical Engineering, Pablo de Olavide University, ctra. de Utrera km 1, 41013, Sevilla, Spain 2 Botanic Garden of Madrid, CSIC, Pza. Murillo n° 2, 28014, Madrid, Spain Author for correspondence: Santiago Martín-Bravo, [email protected] Abstract Reseda sect. Glaucoreseda is a monophyletic group composed of five endemic tetraploid species with a disjunct dis- tribution in the high mountains and plateaus of the Iberian Peninsula and Morocco. It was previously suggested that range shifts induced by Quaternary glaciations played an important role in the speciation of the group. We studied the evolution of R. sect. Glaucoreseda in order to infer historical range dynamics and speciation processes, and to understand current distributional pat- terns. Phylogeographic analyses were performed using nuclear ribosomal ITS and plastid trnL-F and rps16 sequences. Cloning of additive ITS sequences was carried out to elucidate the origin of intra-individual polymorphisms. A dated phylogeny based on ITS and cpDNA (rbcL, matK, trnL-F) sequences was used to estimate divergence times of R. sect. Glaucoreseda. Time estimates using Penalized Likelihood analyses indicate a late Pleistocene diversification of R. sect. Glaucoreseda. Incomplete lineage sorting of ancestral polymorphisms due to recent divergence, rather than rampant hybridisation, is suggested as the main cause of the phylogenetic incongruence detected between nuclear and plastid datasets. -

Hellebore Faqs by Post Office Farm Nursery
Hellebore FAQs By Post Office Farm Nursery Can I grow Hellebores where I live? Hellebores are temperate climate plants. They like a cool to cold Winter and not too much humidity. So Hellebores can be grown anywhere in Tasmania and Victoria. Temperate areas of South Australia, including Adelaide and surrounds, are fine for Hellebores. In NSW Hellebores can be grown in coastal areas up to about Newcastle. Coastal areas further North than this will be too humid for Hellebores. So Hellebores can be grown in Sydney and will be particularly at home in the Southern Highlands and Blue Mountains. In inland areas of NSW Hellebores enjoy the cold Winters and can be grown well in non-arid areas from Wagga, Canberra through Bathurst, to Armidale. In Queensland Hellebores can only be grown in higher altitude Southeastern inland area such as Stanthorpe, Warwick and Toowoomba. Where should I plant my Hellebores? Planting Hellebores in the correct position in the garden is the key to growing them successfully. In the wild Hellebores are found in and around deciduous woodland. They are adapted to having shade for most or all of the day in Summer (when the trees are in leaf) and good light if not full sun over Winter (when the woodland canopy is bare). So while it is true that Hellebores are ‘shade plants’, it is deciduous rather than year round evergreen shade that they want. Indeed planting Hellebores under large evergreen shrubs and trees is the most common mistake made when planting Hellebores. If too dark under evergreen shade in Winter, Hellebore will not grow and flower to their potential. -

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. -
BIODIVERSITY CONSERVATION on the TIWI ISLANDS, NORTHERN TERRITORY: Part 1. Environments and Plants
BIODIVERSITY CONSERVATION ON THE TIWI ISLANDS, NORTHERN TERRITORY: Part 1. Environments and plants Report prepared by John Woinarski, Kym Brennan, Ian Cowie, Raelee Kerrigan and Craig Hempel. Darwin, August 2003 Cover photo: Tall forests dominated by Darwin stringybark Eucalyptus tetrodonta, Darwin woollybutt E. miniata and Melville Island Bloodwood Corymbia nesophila are the principal landscape element across the Tiwi islands (photo: Craig Hempel). i SUMMARY The Tiwi Islands comprise two of Australia’s largest offshore islands - Bathurst (with an area of 1693 km 2) and Melville (5788 km 2) Islands. These are Aboriginal lands lying about 20 km to the north of Darwin, Northern Territory. The islands are of generally low relief with relatively simple geological patterning. They have the highest rainfall in the Northern Territory (to about 2000 mm annual average rainfall in the far north-west of Melville and north of Bathurst). The human population of about 2000 people lives mainly in the three towns of Nguiu, Milakapati and Pirlangimpi. Tall forests dominated by Eucalyptus miniata, E. tetrodonta, and Corymbia nesophila cover about 75% of the island area. These include the best developed eucalypt forests in the Northern Territory. The Tiwi Islands also include nearly 1300 rainforest patches, with floristic composition in many of these patches distinct from that of the Northern Territory mainland. Although the total extent of rainforest on the Tiwi Islands is small (around 160 km 2 ), at an NT level this makes up an unusually high proportion of the landscape and comprises between 6 and 15% of the total NT rainforest extent. The Tiwi Islands also include nearly 200 km 2 of “treeless plains”, a vegetation type largely restricted to these islands. -
