Cover: Map of endemicity (the number of unique species not found anywhere else) for the Northern Territory. The red focus is the Arnhemland Plateau. Image is from Woinarski et al. (2006). Reprinted with the kind permission of CSIRO Publishing. Preface: Recommendations and acknowledgments As the image on the cover of this plan indicates, the Arnhemland Plateau is truly unique. In the past it has perhaps been under-appreciated because of its isolation and distance from our day to day lives. However, it is in many respects the Northern Territory’s Amazon: a region of unparalleled diversity and beauty that is worth protecting at all costs. The purpose of this management plan is to set a framework for monitoring and managing the Plateau that will hopefully prove useful for coordinating fire management and monitoring its success. A few of the techniques recommended, particularly increased emphasis on walking, and the introduction of fire suppression, have been talked about but perhaps not emphasized enough in the past. Integrating management of the Plateau as a whole unit rather than by district is an important development of this plan, to be sure.

This paper is the first to report observations on the leaf-indumentum of 33 species of the tribe with Scanning Electron Microscopy. Apart from simple hairs and papillae, three types of stellate trichomes were observed: fasciculate hairs, appressed stellate hairs and multiradiate hairs (sessile or stalked). The existence of stellate trichomes on the examined species of Pomaderreae was confirmed. Trichomes and indumenta are often variable within genera, as the type of indumentum may be more related to its function. Some groups of species in the genera Cryptandra Sm., Pomaderris Labill. and Stenanthemum Reissek have indumentum characters that seem to be more consistent and might be of value to elucidate relationships between taxa. Keywords: Rhamnaceae, Pomaderreae, leaf morphology, trichomes, hairs, leaf surface, SEM Introduction xeromorphic adaptations, such as small, hard, revolute or conduplicate leaves, a dense indumentum or spines.

  • Evolutionary Relationships in Eucalyptus Sens. Lat. – a Synopsis

    Evolutionary Relationships in Eucalyptus Sens. Lat. – a Synopsis

    Euclid - Online edition Evolutionary relationships in Eucalyptus sens. lat. – a synopsis This article complements the introductory essay about eucalypts included in the "Learn about Eucalypts" section. Its aim is to provide an up-to-date account of the outcomes of research derived from different groups during the past 5 years relating to relationships within Eucalyptus s.s. As such it includes only those publications and hypotheses relating to higher level relationships of major groupings within the eucalypts. Some of the research reported below also provides insights into biogeographic relationships of the eucalypt group – in large part these are not the focus of this article and are not discussed in detail. Introduction The first comprehensive classification of the eucalypts was published by Blakely in 1934, in which he treated more than 600 taxa, building on earlier work of Maiden and Mueller. Blakely's classification remained the critical reference for Eucalyptus taxonomists for the next 37 years when a new but informal classification was published by Pryor and Johnson (1971). In this work the authors divided the genus into seven subgenera, and although of an informal nature, presented a system of great advance on Blakely's treatment. The small genus Angophora was retained. The next 20 years saw much debate about the naturalness of Eucalyptus and whether other genera should be recognized (e.g., Johnson 1987). Based on morphological data, Hill and Johnson in 1995 proposed a split in the genus and recognition of the genus Corymbia. This new genus of c. 113 species, comprised the ghost gums and the bloodwoods, and Hill and Johnson concluded that Corymbia is the sister group to Angophora, with the synapomorphy of the distinctive cap cells on bristle glands (Ladiges 1984) being unambiguous.

Marc MacDonald Department of History, University of Prince Edward Island, 550 University Avenue, Charlottetown, PE C1A 4P3, Canada; [email protected]; Tel.: +1-902-569-4865 Academic Editor: Bryan L. Sykes Received: 16 July 2016; Accepted: 3 January 2017; Published: 10 January 2017 Abstract: Modernity does not possess a monopoly on mass incarceration, population fears, forced migration, famine, or climatic change. Indeed, contemporary and early modern concerns over these matters have extended interests in Thomas Malthus. Yet, despite extensive research on population issues, little work explicates the genesis of population knowledge production or how the process of intellectual transfer occurred during the eighteenth and early nineteenth centuries. This paper examines the Delessert network’s instrumental role in cultivating, curating, and circulating knowledge that popularized Malthusian population theory, including the theory’s constitutive elements of political economy, philanthropy, industry, agriculture, and botany. I show how deviant, nonconformist groups suffered forced migration for their political philosophy, particularly during the revolutionary 1790s, resulting in their imprisonment and migration to America. A consequence of these social shifts was the diffusion and dissemination of population theory—as a pursuit of scientific knowledge and exploration—across both sides of the Atlantic. By focusing on the Delesserts and their social network, I find that a byproduct of inter and intra continental migration among European elites was a knowledge exchange that stimulated Malthus’s thesis on population and Genevan Augustin Pyramus Candolle’s research on botany, ultimately culminating in Charles Darwin’s theory of natural selection and human evolution.

    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.
