A Limiting Factor
Published on Plants in Action (http://plantsinaction.science.uq.edu.au/edition1) Home > Printer-friendly > Printer-friendly Chapter 15 - Water: a limiting factor [1] A superb stand of flooded gums, (Eucalyptus grandis) near Coffs Habour, northern New South Wales, 'each tall because of each' (Les Murray (1991), Collected Poems) (Photograph by Ken Eldridge, supplied by Peter Burgess, CSIRO Forestry and Forest Products) With perspective phrasing, Les Murray (1991) summarises structural aspects of a gum forest as: 'Flooded gums on creek ground, each tall because of each' and on conceptualising water relations, 'Foliage builds like a layering splash: ground water drily upheld in edge-on, wax rolled, gall-puckered leaves upon leaves. The shoal life of parrots up there.' (Les Murray, Collected Poems, 1991) Introduction Life-giving water molecules, fundamental to our biosphere, are as remarkable as they are abundant. Hydrogen bonds, enhanced by dipole forces, confer extraordinary physical properties on liquid water that would not be expected from atomic structure alone. Water has the strongest surface tension, biggest specific heat, largest latent heat of vaporisation and, with the exception of mercury, the best thermal conductivity of any known natural liquid. A high specific grav-ity is linked to a high specific heat, and very few natural substances require 1 calorie to increase the temperature of 1 gram by 1ºC. Similarly, a high heat of vaporisation means that 500 calories are required to convert 1 gram of water from liquid to vapour at 100ºC. This huge energy requirement (latent heat of vaporisation, Section 14.5) ties up much heat so that massive bodies of water contribute to climatic stability, while tiny bodies of water are significant for heat budgets of organisms. -
The Pharmacological and Therapeutic Importance of Eucalyptus Species Grown in Iraq
IOSR Journal Of Pharmacy www.iosrphr.org (e)-ISSN: 2250-3013, (p)-ISSN: 2319-4219 Volume 7, Issue 3 Version.1 (March 2017), PP. 72-91 The pharmacological and therapeutic importance of Eucalyptus species grown in Iraq Prof Dr Ali Esmail Al-Snafi Department of Pharmacology, College of Medicine, Thi qar University, Iraq Abstract:- Eucalyptus species grown in Iraq were included Eucalyptus bicolor (Syn: Eucalyptus largiflorens), Eucalyptus griffithsii, Eucalyptus camaldulensis (Syn: Eucalyptus rostrata) Eucalyptus incrassate, Eucalyptus torquata and Eucalyptus microtheca (Syn: Eucalyptus coolabahs). Eucalypts contained volatile oils which occurred in many parts of the plant, depending on the species, but in the leaves that oils were most plentiful. The main constituent of the volatile oil derived from fresh leaves of Eucalyptus species was 1,8-cineole. The reported content of 1,8-cineole varies for 54-95%. The most common constituents co-occurring with 1,8- cineole were limonene, α-terpineol, monoterpenes, sesquiterpenes, globulol and α , β and ϒ-eudesmol, and aromatic constituents. The pharmacological studies revealed that Eucalypts possessed gastrointestinal, antiinflammatory, analgesic, antidiabetic, antioxidant, anticancer, antimicrobial, antiparasitic, insecticidal, repellent, oral and dental, dermatological, nasal and many other effects. The current review highlights the chemical constituents and pharmacological and therapeutic activities of Eucalyptus species grown in Iraq. Keywords: Eucalyptus species, constituents, pharmacological, therapeutic I. INTRODUCTION: In the last few decades there has been an exponential growth in the field of herbal medicine. It is getting popularized in developing and developed countries owing to its natural origin and lesser side effects. Plants are a valuable source of a wide range of secondary metabolites, which are used as pharmaceuticals, agrochemicals, flavours, fragrances, colours, biopesticides and food additives [1-50]. -
Influence of Leaf Chemistry on Dietary Choice and Habitat Quality of Koala (Phascolarctos Cinereus) Populations in Southwest Queensland
Influence of leaf chemistry on dietary choice and habitat quality of koala (Phascolarctos cinereus) populations in southwest Queensland Huiying Wu Master of Science A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2017 School of Earth and Environmental Sciences Abstract Protecting high quality habitat is an important wildlife conservation action. Spatial and temporal variation in habitat quality in heterogeneous landscapes influences habitat use and population persistence. Populations living at the margins of species’ geographic ranges are particularly sensitive to fluctuations in habitat quality, especially if species occupy narrow ecological niches. For arboreal folivores, foliar chemical composition is a key factor influencing habitat quality. To understand the spatial and temporal dynamics of foliar chemistry and hence the habitat quality for an arboreal folivore species, I applied theories and methods from chemical ecology, nutritional ecology and landscape ecology to understand foliar chemical/folivore interactions in a seasonally changing environment. I used populations of koalas (Phascolarctos cinereus) in two semi-arid regions of Queensland, Australia, as a case study. Koalas are specialist folivores with complex feeding behaviour from Eucalyptus species. My aim was to identify the influence of foliar chemicals (moisture content, digestible nitrogen (DigN) and a toxin formylated phloroglucinol compounds (FPC) concentrations) and associated environmental factors on koala habitat use -
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. -

O’Keefe, R. Milne, S. Gowans, C. Harding and K. Callister Centre for Environmental Management, University of Ballarat, PO Box 663 Ballarat, Victoria 3353, AUSTRALIA Abstract: The vegetation of Peery Lake area, Paroo-Darling National Park (32°18’–32°40’S, 142°10’–142°25’E) in north western New South Wales was assessed using intensive quadrat sampling and mapped using extensive ground truthing and interpretation of aerial photograph and Landsat Thematic Mapper satellite images. 378 species of vascular plants were recorded from this survey from 66 families. Species recorded from previous studies but not noted in the present study have been added to give a total of 424 vascular plant species for the Park including 55 (13%) exotic species. Twenty vegetation communities were identified and mapped, the most widespread being Acacia aneura tall shrubland/tall open-shrubland, Eremophila/Dodonaea/Acacia open shrubland and Maireana pyramidata low open shrubland. One hundred and fifty years of pastoral use has impacted on many of these communities. Cunninghamia (2003) 8(1): 111–128 Introduction Elder and Waite held the Momba pastoral lease from early 1870 (Heathcote 1965). In 1889 it was reported that Momba Peery Lake area of Paroo–Darling National Park (32°18’– was overrun by kangaroos (Heathcote 1965). About this time 32°40’S, 142°10’–142°25’E) is located in north western New a party of shooters found opal in the sandstone hills and by South Wales (NSW) 110 km north east of Broken Hill the 1890s White Cliffs township was established (Hardy (Figure 1). -
Trees, Shrubs, and Perennials That Intrigue Me (Gymnosperms First
Big-picture, evolutionary view of trees and shrubs (and a few of my favorite herbaceous perennials), ver. 2007-11-04 Descriptions of the trees and shrubs taken (stolen!!!) from online sources, from my own observations in and around Greenwood Lake, NY, and from these books: • Dirr’s Hardy Trees and Shrubs, Michael A.

(I’m not sure if this is true for the rosids and asterids, starting on page 30. I just listed them in the same order as Angiosperm Phylogeny Group II.) This document started out as my personal landscaping plan and morphed into something almost unwieldy and phantasmagorical. Key to symbols and colored text: Checkboxes indicate species and/or cultivars that I want. Checkmarks indicate those that I have (or that one of my neighbors has). Text in blue indicates shrub or hedge. (Unfinished task – there is no text in blue other than this text right here.) Text in red indicates that the species or cultivar is undesirable: • Out of range climatically (either wrong zone, or won’t do well because of differences in moisture or seasons, even though it is in the “right” zone). • Will grow too tall or wide and simply won’t fit well on my property. -

Hyphal morphology, susceptibility of spheroplasts and uptake of propidium iodide following exposure to the oil suggest that the mode of action of L. petersonii essential oil is through direct disturbance of the fungal cell membrane. Data also confirms that the volatile component of the oil is highly antifungal, independent of direct contact between the liquid oil and the fungal membrane. The degree of inhibition was greater when fungi were directly exposed to oil volatiles compared to pre- inoculation exposure of oil volatiles into the agar. It is likely that the essential oil volatiles are acting both directly and indirectly on the fungi to produce growth inhibition.
