This volume summarises experiences shared, priorities identified and joint actions defined during the workshop. From formal presentations and field visits, as well as formal and informal discussions, it was clear that numerous Invasive Alien Species (IAS) management activities are being undertaken in the region. In La Réunion efforts are well advanced towards implementing a risk assessment procedure for proposed new plant introductions (le Bourgeois et. al). Species-led IAS management work has been undertaken in La Réunion (le Bourgeois et al., Brondeau & Hivert), Seychelles (Vielle) and Mauritius (Gopal). Area-led management has been undertaken in La Réunion (Triolo), Mauritius (Gopal), Rodrigues (Payendee) and Seychelles (Barreau, Kueffer), including some exemplary islet restoration efforts in Mauritius (Gopal, Mauremootoo) and Seychelles (Hill et al.). Little information exists on the efficacy of this restoration work although opportunistic monitoring has been undertaken in Mauritius (Florens) and is being attempted on a more systematic level in La Réunion through the INVABIO project (Lavergne et al.) Sharing experience has been hampered by a lack of accessible information on the IAS situation in the region. This shortcoming is now being redressed by initiatives such as the current workshop and the FAO regional assessment of invasive woody species in the region (Kueffer and Vos). Efforts to summarise anecdotal information and grey literature are exemplified by the synthesis of weed control methods in undertaken by ONF in La Réunion (Brondeau & Hivert). International initiatives such as the Global Invasive Species Programme (GISP), the Cooperative Islands Initiative (CII) and others (Boudjelas) can complement national and regional efforts in IAS management. The potential benefit of such initiatives has been increased by advances in communications technology, manifested by the increasing amount of valuable information on IAS now available on the web (Annexes 8 and 9). Finding sufficient resources for IAS management is a challenge, notably in the IFR Comoros where basic needs are inevitably prioritised above biodiversity conservation

The present study represents the most comprehensive taxonomic sampling of any freshwater crab family globally, and explores the impact of paleodrainage interconnectivity on cladogenesis among freshwater crabs. Phylogenetic analyses of the total evidence data using maximum-likelihood (ML), maximum parsimony (MP), and Bayesian inference (BI) produced a robust statistically well-supported tree topology that reaffirmed the monophyly of the Afrotropical freshwater crab fauna.

    Zootaxa 422: 1–27 (2004) ISSN 1175-5326 (print edition) www.mapress.com/zootaxa/ ZOOTAXA 422 Copyright © 2004 Magnolia Press ISSN 1175-5334 (online edition) Erimetopus vandenbrandeni (Balss, 1936) n. comb., with notes on the taxonomy of the genus Erimetopus Rathbun, 1894 (Brachyura: Potamoidea: Potamonautidae) from Central Africa NEIL CUMBERLIDGE1 & SADIE K. REED Department of Biology, Northern Michigan University, Marquette, Michigan 49855, USA 1 [email protected] Abstract The Central African freshwater crab genus Erimetopus (family Potamonautidae) is revived to accommodate two species, E. brazzae (A. Milne-Edwards, 1886) and E. vandenbrandeni (Balss, 1936) n. comb. The genus Erimetopus Rathbun, 1894, and the two species assigned to it here, are redescribed from type material, and lectotypes for each species are selected. Erimetopus spinosus Rathbun, 1894 is judged here to be a junior synonym of E. brazzae, and P. (E.) b. frontospinulosa is treated as a subspecies of E. brazzae. Illustrations and photographs of the type specimens of these taxa are provided, and new gonopod evidence based on E. vandenbrandeni is evaluated. The distri- butions of the species of Erimetopus are described and discussed, and keys to the genera of African freshwater crabs and to the species of Erimetopus are provided. Key words: Crustacea, Brachyura, Potamoidea, Potamonautidae, Erimetopus, freshwater crab, tax- onomy, Central Africa, natural history, Congo River, rainforest Introduction This work aims to stabilize the taxonomy of the little-known Central African freshwater crab genus Erimetopus Rathbun, 1894, which is endemic to the lower Congo River and its tributaries. Erimetopus has long attracted the interest of carcinologists because its subhex- agonal/rounded carapace outline and distinctive arrangement of spines on the carapace margins and pereopods not only distinguish it from other genera of potamonautid freshwa- ter crabs found in Africa (Cumberlidge 1999), but also impart a superficial resemblance to some species of South American trichodactylid freshwater crabs (see below).

  • Invasive Alien Plants Elicit Reduced Production of Flowers and Fruits in Various Native Forest Species on the Tropical Island of Mauritius (Mascarenes, Indian Ocean)
    Mongabay.com Open Access Journal - Tropical Conservation Science Vol.6 (1):35-49, 2013 Research Article Invasive alien plants elicit reduced production of flowers and fruits in various native forest species on the tropical island of Mauritius (Mascarenes, Indian Ocean). M.L. Fabiola Monty1*, F.B. Vincent Florens1 and Cláudia Baider2 1Department of Biosciences, University of Mauritius, Réduit, Mauritius 2The Mauritius Herbarium, R. E. Vaughan Building, Agricultural Services, Ministry of Agro-Industry and Food Security, Réduit, Mauritius. *Corresponding author, E-mail: [email protected] Abstract Biological invasions constitute a major threat to biodiversity. However, while the impact of invasive alien animals on native biota is often unambiguous, the impacts of invasive alien plants (IAP) appear to be considerably less severe and, at times, more debatable. Invasion by alien plants co-occur with other drivers of habitat change such that assessing impacts of IAP independently of these other factors may be difficult. Generalisations can be misleading, because studies reveal different responses of native plants to the presence of IAP. Therefore, there is a need to understand general trends and exceptions within a particular habitat. In the island of Mauritius, mechanical control of invasive alien plants has been implemented for decades in lowland wet forests. Weeded and non-weeded areas are very similar in all aspects, except for the control of IAP, providing an opportunity to study how IAP are affecting native plants. We monitored the reproductive output of 20-40 individuals each, of nine selected native species from different forest strata, in both weeded and adjacent non-weeded areas in a lowland wet forest, through direct count/estimation of the number of flower buds, flowers and fruits.
