Isichei Dept. of Botany, Obafemi Awolowo University, Ile-Ife 1.0 Introduction The global problem of biodiversity loss, especially vegetation loss has been of concern since humans realized the implications of habitat destruction in the course of economic development. Plants form the bedrock of life and human material culture depends on them. Our human world has been so closely tied to plants that it is difficult to imagine human existence without them. Being the only primary producers, all other consumers in the food chain are dependent on plants for food, fibre and energy. Knowledge of plants, their habitats, structure, metabolism and inheritance is thus the basic foundation for human survival and the way a people incorporate plants into their cultural traditions, religions and even cosmologies reveals much about the people themselves. People rely on plants for much more than food and shelter and there are a few areas of human endeavour in which plants do not play an important role.

  • An Annotated Checklist of the Angiospermic Flora of Rajkandi Reserve Forest of Moulvibazar, Bangladesh
    Bangladesh J. Plant Taxon. 25(2): 187-207, 2018 (December) © 2018 Bangladesh Association of Plant Taxonomists AN ANNOTATED CHECKLIST OF THE ANGIOSPERMIC FLORA OF RAJKANDI RESERVE FOREST OF MOULVIBAZAR, BANGLADESH 1 2 A.K.M. KAMRUL HAQUE , SALEH AHAMMAD KHAN, SARDER NASIR UDDIN AND SHAYLA SHARMIN SHETU Department of Botany, Jahangirnagar University, Savar, Dhaka 1342, Bangladesh Keywords: Checklist; Angiosperms; Rajkandi Reserve Forest; Moulvibazar. Abstract This study was carried out to provide the baseline data on the composition and distribution of the angiosperms and to assess their current status in Rajkandi Reserve Forest of Moulvibazar, Bangladesh. The study reports a total of 549 angiosperm species belonging to 123 families, 98 (79.67%) of which consisting of 418 species under 316 genera belong to Magnoliopsida (dicotyledons), and the remaining 25 (20.33%) comprising 132 species of 96 genera to Liliopsida (monocotyledons). Rubiaceae with 30 species is recognized as the largest family in Magnoliopsida followed by Euphorbiaceae with 24 and Fabaceae with 22 species; whereas, in Lilliopsida Poaceae with 32 species is found to be the largest family followed by Cyperaceae and Araceae with 17 and 15 species, respectively. Ficus is found to be the largest genus with 12 species followed by Ipomoea, Cyperus and Dioscorea with five species each. Rajkandi Reserve Forest is dominated by the herbs (284 species) followed by trees (130 species), shrubs (125 species), and lianas (10 species). Woodlands are found to be the most common habitat of angiosperms. A total of 387 species growing in this area are found to be economically useful. 25 species listed in Red Data Book of Bangladesh under different threatened categories are found under Lower Risk (LR) category in this study area.

Prosopis juliflora (Sw) DC. (Fabales: Fabaceae: Caesalpinioideae) was introduced in the Caatinga dry forest of Northeast Brazil at early 1940s and successfully spread across the region. As other invasive species, it may benefit from the soils and seed dispersal by livestock.

La dispersión por endozoocoria puede incrementar las probabilidades de supervivencia y acelerar la germinación de las semillas (Howe & Smallwood 1982). En el marco del estudio de animales dispersores de semillas deben evaluarse tres atributos: 1) legitimidad del dispersor 2) eficiencia del dispersor y 3) efectividad del dispersor (Bustamante et al. 1992, Bustamante & Canals 1995). La legitimidad se refiere a la viabilidad de las semillas que pasan por el tracto digestivo y puede cuantificarse como la proporción de semillas defecadas viables (Herrera 1989). La eficiencia suele cuantificarse como la proporción de semillas defecadas en sitios donde puedan germinar y establecerse (Reid 1989); mientras que la efectividad puede evaluarse como la proporción de plántulas reclutadas a través de la diseminación de semillas por un dispersor (Reid 1989).

The study was carried out between April 2018 to February 2019. A total of 49 logged stumps were selected within the Akak forest spanning a period of 5 years and 20m x 20m transects were demarcated. All plants species <1cm and above were identified and recorded. Results revealed that a total of 5239 individuals from 71 families, 216 genera and 384species were identified in the study area. The maximum plants species was recorded in the year 2015 (376 species). The maximum number of species and regeneration potentials was found in the family Fabaceae, (99 species) and (31) respectively. Baphia nitida, Musanga cecropioides and Angylocalyx pynaertii were the most dominant plants specie in the years 2013, 2015 and 2017 respectively. The year 2017 depicts the highest Simpson diversity with value of (0.989) while the year 2015 show the highest Simpson dominance with value of (0.013).

Santa Isabel 1186, Santiago, Chile. *[email protected] RESUMEN Myrcianthes coquimbensis es una especie endémica de Chile en peligro de extinción, con una distribución restringida en la costa de la Región de Coquimbo. En la actualidad su hábitat está siendo fuertemente impactado por desarrollos inmobiliarios. La especie presenta valor ornamental; sin embargo, desde el punto de vista paisajístico es poco conocido. En esta investigación se estudió la propagación por semillas y vegetativa por esquejes, con fines de conservación ex situ. En ensayos de germinación se encontró que la cinética de este proceso varió significativamente según la época de siembra (invierno o verano). Así después de 90 días de siembra se observó un 51% de germinación en verano, mientras en invierno sólo alcanzó el 29%. También se observó un efecto inhibitorio del pericarpio sobre la germinación, disminuyendo un 50% la germinación. La incubación de semillas en GA3 (24 h) incrementó el porcentaje de germinación dependiendo de la dosis. Se realizaron ensayos de enraizamiento de esquejes con tratamientos de AIB en cama fría y cama caliente. En cama fría se observó una baja respuesta (8,44%), y no mostró relación con los tratamientos de AIB. En contraste a lo anterior, en cama caliente el enraizamiento alcanzó un 33% con aplicación de 3.000 ppm de AIB.

T Lo que muchas veces no consideramos es que los ambientes naturales de los cuales disfrutamos, por ejemplo cuando hacemos vida al aire libre, son entidades dinámicas, que se puede describir y entender a partir de los elementos que la componen y de las fun- ciones que cumplen y que la presencia de los seres humanos, sus actividades y sus efectos, pueden modificar tanto la disposición como la función de estos elementos en el ambiente. Por ejemplo, nuestras actividades productivas o incluso de esparcimiento, suelen generar impactos sobre la flora y la fauna, sobre los suelos y el aire y evidentemente sobre el paisaje. Si bien este manual está destinado a divulgar la importancia de una especie de plan- ta propia de la región de Coquimbo, es también una invitación a todas aquellas personas que se sienten atraídas por la naturaleza, a repensar la forma en que los seres humanos nos acercamos e interactuamos con los espacios naturales.
