Resource Partitioning Among Five Sympatric Mammalian Herbivores on Yanakie Isthmus, South- Eastern Australia
Resource partitioning among five sympatric mammalian herbivores on Yanakie Isthmus, south- eastern Australia Naomi Ezra Davis Submitted in total fulfilment of the requirements of the degree of Doctor of Philosophy September 2010 Department of Zoology The University of Melbourne i Abstract This thesis combines multiple approaches to improve our understanding of large herbivore ecology and organisation in a contemporary assemblage made up of species with independent evolutionary histories on Yanakie Isthmus, Wilsons Promontory National Park, Victoria, Australia. In particular, this thesis compares niche parameters among populations of five sympatric native and introduced herbivore species by simultaneously assessing overlap in resource use along two dimensions (spatial and trophic) at multiple scales, thereby providing insight into resource partitioning and competition within this herbivore assemblage. Faecal pellet counts demonstrated that inter-specific overlap in herbivore habitat use on Yanakie Isthmus was low, suggesting that spatial partitioning of habitat resources had occured. However, resource partitioning appeared to be independent of coevolutionary history. Low overlap in habitat use implies low competition, and the lack of clear shifts in habitat use from preferred to suboptimal habitats suggested that inter-specific competition was not strong enough to cause competitive exclusion. However, low overlap in habitat use between the European rabbit Oryctolagus cuniculus and other species, and preferential use by rabbits (and avoidance by other species) of the habitat that appeared to have the highest carrying capacity, suggested that rabbits excluded other grazing herbivores from preferred habitat. High overlap in habitat use was apparent between some species, particularly grazers, indicating some potential for competition if resources are limiting. -

Plant Life of Western Australia
INTRODUCTION The characteristic features of the vegetation of Australia I. General Physiography At present the animals and plants of Australia are isolated from the rest of the world, except by way of the Torres Straits to New Guinea and southeast Asia. Even here adverse climatic conditions restrict or make it impossible for migration. Over a long period this isolation has meant that even what was common to the floras of the southern Asiatic Archipelago and Australia has become restricted to small areas. This resulted in an ever increasing divergence. As a consequence, Australia is a true island continent, with its own peculiar flora and fauna. As in southern Africa, Australia is largely an extensive plateau, although at a lower elevation. As in Africa too, the plateau increases gradually in height towards the east, culminating in a high ridge from which the land then drops steeply to a narrow coastal plain crossed by short rivers. On the west coast the plateau is only 00-00 m in height but there is usually an abrupt descent to the narrow coastal region. The plateau drops towards the center, and the major rivers flow into this depression. Fed from the high eastern margin of the plateau, these rivers run through low rainfall areas to the sea. While the tropical northern region is characterized by a wet summer and dry win- ter, the actual amount of rain is determined by additional factors. On the mountainous east coast the rainfall is high, while it diminishes with surprising rapidity towards the interior. Thus in New South Wales, the yearly rainfall at the edge of the plateau and the adjacent coast often reaches over 100 cm. -

As we have already announced, Hamilton and Warrnambool & District Group have joined forces to present the next Fred Rogers Seminar at Hamilton in 2016 on the subject of “Terrestrial and Epiphytic Orchids”. 28th April - Committee Meeting We inspected the proposed seminar venue at Hamilton and Alexandra College, this private college is well set up to provide all the facilities we could possibly need and we very quickly decided that this is where we would run our seminar. Our planning is still at a very early stage yet but we will have to start making some decisions soon so that we can begin promoting the event. -

Final Report for the Australian Flora Foundation Inc
Seed biology of Australian euphorbs: South Australia Port Gawler New South Wales Coffin Bay Marion Bay Wyperfeld Torrens Island Victoria Robe Carpenter's Rocks 0 150 300 Kilometers Areas used for collection of seed of Adriana species Final Report for the Australian Flora Foundation Inc by Dr Duncan Mackay and Dr Molly A. Whalen School of Biological Sciences, Flinders University, Adelaide 29 March 1998 1 Seed biology of Australian euphorbs: Final Report for the Australian Flora Foundation Inc; Dr Duncan Mackay and Dr Molly A. Whalen School of Biological Sciences, Flinders University, Adelaide 29 March 1998 Summary Within the Euphorbiaceae, many species have seeds that bear an appendage called a caruncle, although carunculate seeds have a sporadic taxonomic distribution, with some euphorb genera containing both carunculate and ecarunculate species (Webster 1994). The euphorb caruncle is often assumed to function as an elaiosome, that is, as an appendage that facilitates seed dispersal by ants, or myrmecochory. This assumption has received very little quantitative or experimental verification. Our work on the euphorb Adriana concentrated on determining whether or not carunculate seeds are dispersed by ants and whether or not the caruncle is an attractant to seed-dispersing ants. Together, the field and laboratory choice trials indicated that the caruncle is attractive to ants and that carunculate seeds are particularly attractive to omnivorous ants of the genera Rhytidoponera and Iridomyrmex. Since elaiosomes have been hypothesised to have evolved so as to resemble arthropods in their fatty acid composition, we compared the fatty acid compositions of blowflies and Adriana seed and caruncles. Blowflies resembled Adriana caruncles in having relatively low concentrations (10%) of linoleic acid and intermediate concentrations (18%) of palmitic acid, in contrast to Adriana seeds which have relatively high concentrations (62%) of linoleic acid and relatively low concentrations (5%) of palmitic acid. -
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. -
