  • Rain Forest Expansion Mediated by Successional Processes in Vegetation Thickets in the Western Ghats of India
    Journal of Biogeography, 30, 1067–1080 Rain forest expansion mediated by successional processes in vegetation thickets in the Western Ghats of India Jean-Philippe Puyravaud*, Ce´line Dufour and Subramanian Aravajy French Institute of Pondicherry, Pondicherry, India Abstract Aim The objective of this study was to document succession from grassland thickets to rain forest, and to provide evidence for their potential as restoration tools. Location The Linganamakki region (State of Karnataka) of the Central Western Ghats of India. Method We selected thirty vegetation thickets ranging from 4 to 439 m2 in area in the vicinity of rain forest. The area of each small thicket was estimated as an oval using its maximum length and its maximum width. When the shape was irregular (mostly in large thickets) the limits of the thicket were mapped and the area calculated from the map. Plant species were identified, the number of individuals was estimated and their heights measured. Results There was a progression in the thickets from early to late successional species. Small thickets were characterized by ecotone species and savanna trees such as Catun- aregam dumetorum. Savanna trees served as a nucleus for thicket formation. Colonizing species were mostly bird-dispersed. As succession proceeded in larger thickets, the proportion of evergreen, late-successional rain forest trees increased. The species com- position of the large thickets differed depending on the species composition of repro- ductive adults in the nearby forested areas. The species within small thickets were also found in the large thickets. The nestedness in species composition suggested that species turnover was deterministic based on thicket size.

The new IUCN Red List criteria have been revised by IUCN to reflect the need for greater objectivity and precision when categorising species for conservation action. The CAMP process, developed by the Conservation Breeding Specialist Group, has emerged as an effective, flexible, participatory and scientific methodology for conducting species prioritisation exercises using the IUCN criteria. Since 1995, the Foundation for Revitalisation of Local Health Traditions has been con- ducting CAMP Workshops for one of the major groups of conservation concern, medici- nal plants.

Study of its wood anatomy is of interest for understanding adaptation to the liana habit. We set out here to present a general overview of Menispermaceae wood. The wood anatomy of 77 species of 44 genera, representative of an tribes and from an continents, is described. The wood of 18 of these genera was previously unknown. We observed two secondary growth types within the family: wood with successive cambia and wood with a single cambium. The distribution of these types is partly consistent with the c1assification of the family by Diels. General characters of the family are: wide rays, enlarged vessel pits near the perforation plates, and pitted tyloses. The fun range of wood anatomical diversity is given in Table 1. Key words: Menispermaceae, wood, successive cambia, cambial variants. INTRODUCTION The bark of some species of Menispermaceae is wen known for its use in the preparation of dart poisons in South America, named curare. Although Menispermaceae wood is an important material for pharmacological studies for identifying new alkaloids (N'Guyen, pers. comm.), this special interest of phytochemists contrasts with the relative paucity of anatomical knowledge of the family. A better knowledge of Menispermaceae wood is also important for palaeobotanical studies, to enable fossil woods of this family to be more precisely identified (Vozenin-Serra et al.

One species is a shrub (Cocculus laurifolius), one a subshrub (C. trilobus), and the remainder are lianas. Successive cambia are analyzed with respect to ontogeny and histology of products. Wheth­ er any Menispermaceae may or may not plesiomorphically lack successive cambia would require a more extensive survey of the family. Apomorphic absence of successive cambia is likely for species with subshrub growth forms (Cocculus trilobus, Menispermum canadense L.). Lianoid Menisperma­ ceae share the following features: successive cambia, wide vessels, wide rays, high conductive area per transectional unit area, and tracheids as imperforate tracheary elements. All of these features are more common in lianoid dicotyledons than in their nonlianoid relatives. Vessels are solitary in the lianoid species on account of tracheid presence, but grouped in Cocculus trilobus, which has septate libriform fibers.
