Loss of Pathogens in Threatened Plant Species
Oikos 119: 1919–1928, 2010 doi: 10.1111/j.1600-0706.2010.18616.x © 2010 Th e Authors. Oikos © 2010 Nordic Society Oikos Subject Editor: Hamish McCallum. Accepted 7 May 2010 Loss of pathogens in threatened plant species Amanda K. Gibson, Jorge I. Mena-Ali and Michael E. Hood A. K. Gibson, J. I. Mena-Ali and M. E. Hood ([email protected]), Dept of Biology, McGuire Life Sciences Building, Amherst College, Rts 9 and 116, Amherst, MA 01002-5000, USA. Global declines in biodiversity create an urgent need to address the impact of infectious disease in the small and fragmented populations that characterize threatened species. However, the paucity of empirical data provides little ability to pre- dict whether disease generally accelerates threatened species towards extinction or becomes less important as populations decline. Th is study tests whether plant species threatened with extinction exhibit lower disease frequencies and lower over- all parasite species richness while also experimentally testing for the eff ect of physiological disease resistance. Herbarium surveys of the genus Silene revealed that anther-smut disease was signifi cantly less frequent in threatened species than non-threatened species, and this eff ect was not constrained by the host phylogeny or by physiological resistance. Moreover, analysis across a much broader range of plants (using US Federal designations) revealed that species with endangered status had signifi cantly lower species richness of fungal pathogens than closely-related, non-endangered species. Th ese results support the role of host ecology, rather than physiological resistance or phylogeny, in determining overall lower incidences and diversity of diseases in plant species threatened by extinction. -
Scrub Mint Dicerandra Frutescens Shinners
Scrub Mint Dicerandra frutescens Shinners he scrub mint is a small, fragrant shrub that inhabits Federal Status: Endangered (Nov. 1, 1985) the scrub of central peninsular Florida. It bears a Critical Habitat: None Designated Tstrong resemblance to another Dicerandra species, Florida Status: Endangered Garretts mint, but can be differentiated by its scent, the Recovery Plan Status: Revision (May 18, 1999) color of its flowers, and the size of its leaves. Loss of habitat due to residential and agricultural development (particularly Geographic Coverage: Rangewide for citrus groves), as well as fire suppression in tracts of remaining habitat, are the principle threats to this plant. This account represents a revision of the existing Figure 1. County distribution of scrub mint. recovery plan for the scrub mint (FWS 1987). Description The scrub mint is a dense or straggly, low-growing shrub (Kral, 1983). It reaches 50 cm in height and grows from a deep, stout, spreading-branching taproot. Its branches are mostly spreading, and sometimes are prostrate. Its shoots have two forms, one which is strictly leafy and overwintering, and another which is flowering and dies back after fruiting. The leaves vary in shape. They can be narrowly oblong- elliptic, linear-elliptic, or linear-oblanceolate (Kral 1983). The upper surface of the leaves is dark green, with the midrib slightly impressed. The lower surface is slightly paler, with the midrib slightly raised. They are 1.5 to 2.5 cm long, 2 to 3 mm wide, subsessile, flattish but somewhat fleshy, narrowly or broadly rounded at the apical end, have entire margins, and are not revolute. -

Woody Plant Diversity of Banaras Hindu University Main Campus, India
International Journal of Research in Agriculture and Forestry Volume 2, Issue 8, August 2015, PP 25-35 ISSN 2394-5907 (Print) & ISSN 2394-5915 (Online) Woody Plant Diversity of Banaras Hindu University Main Campus, India 1 Arvind Singh 1Department of Botany, Banaras Hindu University, Varanasi, India ABSTRACT A study was conducted to explore the woody species diversity of Banaras Hindu University main campus spreading over 1,350 acres of land area. A total of 330 species of woody plants were recorded from the university campus of which 312 woody species belonging to 184 genera and 55 families were represented by the Angiosperms while 18 woody species belonging to 8 genera and 5 families were represented by the Gymnosperms. The Fabaceae, Euphorbiaceous and Apocynaceae were the dominant families of the woody species composition of university campus. The exotic woody species were greater in number compared to native woody species on the Banaras Hindu University main campus. Keywords: Banaras Hindu University, exotic woody species, native woody species, woody plants, Varanasi district INTRODUCTION The great seat of learning Banaras Hindu University was founded by great freedom fighter and social reformer Pandit Madan Mohan Malaviya (1861-1946) during the Indian freedom movement as a national university with donation from both rich and poor. The foundation stone of this great university was laid by Lord Hardinge on 4 February 1916, the then Governor General of British ruled India. This vast university presently has two campuses, 4 institutes, 16 faculties, 140 departments, 4 advanced centers and 4 interdisciplinary centers and a constituent college for women and 3 constituent schools. -
Staminal Evolution in the Genus Salvia (Lamiaceae): Molecular Phylogenetic Evidence for Multiple Origins of the Staminal Lever
Staminal Evolution In The Genus Salvia (Lamiaceae): Molecular Phylogenetic Evidence For Multiple Origins Of The Staminal Lever Jay B. Walker & Kenneth J. Sytsma (Dept. of Botany, University of Wisconsin, Madison) Annals of Botany (in press) Abstract • Background and Aims - The genus Salvia has traditionally included any member of the tribe Mentheae (Lamiaceae) with only two stamens and with each stamen expressing an elongate connective. The recent demonstration of the non-monophyly of the genus presents interesting implications for staminal evolution in the tribe Mentheae. In the context of a molecular phylogeny, we characterize the staminal morphology of the various lineages of Salvia and related genera and present an evolutionary interpretation of staminal variation within the tribe Mentheae. • Methods. Two molecular analyses are presented in order to investigate phylogenetic relationships in the tribe Mentheae and the genus Salvia. The first presents a tribal survey of the Mentheae and the second concentrates on Salvia and related genera. Schematic sketches are presented for the staminal morphology of each major lineage of Salvia and related genera. • Key Results. These analyses suggest an independent origin of the staminal elongate connective on at least three different occasions within the tribe Mentheae, each time with a distinct morphology. Each independent origin of the lever mechanism shows a similar progression of staminal change from slight elongation of the connective tissue separating two fertile thecae to abortion of the posterior thecae and fusion of adjacent posterior thecae. We characterize a monophyletic lineage within the Mentheae consisting of the genera Lepechinia, Melissa, Salvia, Dorystaechas, Meriandra, Zhumeria, Perovskia, and Rosmarinus. • Conclusions. -

However, we lack demographic data for most species, and the data we have are often geographically aggregated. We determined to what extent existing data can be extrapolated to predict pop- ulation performance across larger sets of species and spatial areas. We used 550 matrix models, across 210 species, sourced from the COMPADRE Plant Matrix Database, to model how climate, geographic proximity and phylogeny predicted population performance. -
