An introduction to the flora of the Milne Bay Archipelago Naturalis
Johns, R.; Gideon, O.; Simaga, J.; Kuria, T.; Bagoera, G..
The term Milne Bay Archipelago is used to include Goodenough, Fergusson and Normanby Islands – collectively the d’Entrecasteau Islands, the islands of the Louisiade Archipelago, Missima, Rossel and Sudest Islands and the two northern islands, the Trobriands and Woodlark. All are very complex with many small islands, often unnamed. Due to their geographic isolation the islands have many endemic species. So far 139 have been described. Of particular interest is the genus Rosselia, collected only twice from Rossel Island. This monotypic genus was placed, with many questions, in the Burseraceae and its current position is uncertain. Another neoendemic genus in Milne Bay is Lamiodendendron. It is a coastal tree scattered on several islands and also coastally on...

Analysis of the contribution and efficiency of the Santuario de la Naturaleza Yerba Loca, 33º S in protecting the regional vascular plant flora (Metropolitan and Fifth regions of Chile) RChHN
ARROYO,MARY T. K; MARTICORENA,CLODOMIRO; MATTHEI,OSCAR; MUÑOZ,MÉLICA; PLISCOFF,PATRICIO.
Santuario de la Naturaleza Yerba Loca (SN Yerba Loca), Metropolitan Region (MR), 33º S, Chile is analyzed for its conservation value and efficiency in protecting native vascular plants in a regional context. The reserve's flora of 500 species and subtaxa was evaluated for species richness, endemism, range size and marginally distributed taxa, using species-area analysis, and tendencies in the floras of the MR (1.434 species and subtaxa) and MR-Fifth regions (1,841 species and subtaxa) to set the regional pattern. The reserve (0.7 % of MR land area and 0.3 % MR-Fifth land area) contains 34 % of the MR and 27% of the MR-Fifth floras, and around 16-17 % of the mediterranean-climate area (regions IV-VIII) flora of central Chile. Veech's Relative Richness Index...

Asellus (Asellus) monticola en Iran (Crustacea, Isopoda, Asellota, Asellidae) Naturalis
Henry, Jean-Paul; Magniez, Guy.
Asellus (Asellus) monticola monticola Birstein, 1932 has been found in a spring in the extreme NW of Iran. Amplifications of the original description of this valid species, which is clearly distinct from A. aquaticus, are given. Contrary to A. aquaticus, A. monticola appears to be strongly endemic and stenotopic; its settlement may have taken place prior to the expansion of A. aquaticus across Europe. Some reflections on the taxonomy and biogeography of the Asellidae of the Transcaucasian region are included.

Astyanax jordanensis (Ostariophysi: Characidae), a new species from the rio Iguaçu basin, Paraná, Brazil Neotropical Ichthyology
Alcaraz,Héctor S. Vera; Pavanelli,Carla S.; Bertaco,Vinicius A..
Astyanax jordanensis, new species, is described from the rio Jacu and rio das Torres, both tributaries to the lower rio Jordão, in the rio Iguaçu basin, Paraná, Brazil. The new species is a member of the A. scabripinnis species complex. Astyanax jordanensis differs from its congeners by several meristic and morphometric characters. Mature males possess bony hooks in the dorsal, pectoral, pelvic, and anal fins, and mature females have a few small bony hooks on the first rays of the anal fin. The presence of these bony hooks in females and the endemism of the ichthyofauna in the rio Jordão are discussed.

Biodiversity, Urban Areas, and Agriculture: Locating Priority Ecoregions for Conservation Ecology and Society
Ricketts, Taylor; World Wildlife Fund; taylor.ricketts@wwfus.org; Imhoff, Marc; NASA's Goddard Space Flight Center; mimhoff@LTPmail.gsfc.nasa.gov.
Urbanization and agriculture are two of the most important threats to biodiversity worldwide. The intensities of these land-use phenomena, however, as well as levels of biodiversity itself, differ widely among regions. Thus, there is a need to develop a quick but rigorous method of identifying where high levels of human threats and biodiversity coincide. These areas are clear priorities for biodiversity conservation. In this study, we combine distribution data for eight major plant and animal taxa (comprising over 20,000 species) with remotely sensed measures of urban and agricultural land use to assess conservation priorities among 76 terrestrial ecoregions in North America. We combine the species data into overall indices of richness and endemism. We...

Biogeographic patterns of Chilean littoral fishes RChHN
OJEDA,F. PATRICIO; LABRA,FABIO A; MUÑOZ,ALEJANDRO A.
In this study, we analyzed the biogeographic patterns of the Chilean littoral fish fauna, including latitudinal trends in teleost and chondrichthyan fish species richness, their distribution range patterns, and their level of endemism, both to the Chilean coast and the Southeastern Pacific. We determined the number and percentage of fish taxa within four different groups based on their biogeographic affinities. This was done, both for teleost and chondrichthyan fishes, at the species, genus and family level. In order to recognise the existence of biogeographic regions, we applied cluster and ordination analyses to the distribution data, using objective bootstrapping techniques at the three taxonomic levels used. We found that littoral fish diversity...

Collection records of Gyldenstolpia planaltensis (Avila-Pires, 1972) (Rodentia, Cricetidae) suggest the local extinction of the species Mastozool. neotrop.
Bezerra,Alexandra M. R..
The genus Gyldenstolpia was recently described and includes two species, G. fronto and G. planaltensis, both very rare. Gyldenstolpia planaltensis had records in only two localities in the central-western Brazil and is endemic to the Cerrado biome. A new locality is added to G. planaltensis, extending its distribution, and was obtained from a specimen housed in a museum collection. Summarized data on the distribution, ecology and natural history of G. planaltensis denotes that this species can be already extinct or committed to extinction because of habitat conversion and habitat loss.

Comparative phylogeography of the western Indian Ocean reef fauna ArchiMer
Borsa, Philippe; Durand, Jean-dominique; Chen, Wei-jen; Hubert, Nicolas; Muths, Delphine; Mou-tham, Gerard; Kulbicki, Michel.
Assessing patterns of connectivity at the community and population levels is relevant to marine resource management and conservation. The present study reviews this issue with a focus on the western Indian Ocean (WIO) biogeographic province. This part of the Indian Ocean holds more species than expected from current models of global reef fish species richness. In this study, checklists of reef fish species were examined to determine levels of endemism in each of 10 biogeographic provinces of the Indian Ocean. Results showed that the number of endemic species was higher in the WIO than in any other region of the Indian Ocean. Endemic species from the WIO on the average had a larger body size than elsewhere in the tropical Indian Ocean. This suggests an...

Description of a new Lithoxus (Siluriformes: Loricariidae) from the Guayana Highlands with a discussion of Guiana Shield biogeography Neotropical Ichthyology
Lujan,Nathan K..
Lithoxus jantjae, new species, is described from above Tencua Falls in headwaters of the Ventuari River, a white- to clearwater river flowing west from the Maigualida and Parima mountains in the Guayana Highlands of southern Venezuela. Lithoxus jantjae represents a nearly 600 km westward range expansion for a genus historically known only from Guyana, Suriname, French Guiana, and Brazil. Lithoxus jantjae shares with other species of Lithoxus a dorsoventrally depressed body and a large, papilose oral disk with small toothcups and few teeth. It can be distinguished from congeners by a unique combination of characters including 12 branched caudal-fin rays, medial premaxillary tooth cusps enlarged, and a convex posterior margin of the adipose-fin membrane....

Distribución ecológica del subgénero Neodawsonia Backeb. del género Cephalocereus Pfeiff. (Cactaceae), en el Itsmo de Tehuantepec, México. Colegio de Postgraduados
Bárcenas Argüello, María Luisa.
Cephalocereus es un género monofilético, cuya distribución es alopátrica y está restringida a la Barranca de Metztitlán (C. senilis), al Valle de Tehuacán-Cuicatlán (C. columna-trajani) y a la cuenca del río Tehuantepec (subgénero Neodawsonia, C. apicicephalium, C. nizandensis, C. totolapensis). Se desconoce qué factores condicionan este patrón de distribución endémico. El objetivo de este trabajo fue el proponer una hipótesis que explique el endemismo de sus especies, a partir de relaciones específicas entre la fisiología de los oxalatos de calcio y las propiedades de las rocas y de los suelos en los que habitan. En cada población se tomaron muestras del material parental (roca) del suelo, se removió tejido vegetal y se recolectaron semillas; estas...

Diversité ichtyologique en Méditerranée : patrons, modélisation et projections dans un contexte de réchauffement global ArchiMer
Ben Rais Lasram, Frida.
Due to its semi-enclosed shape, to its high species richness and high endemism levels and to its invasiveness, the Mediterranean Sea is one of the most particular and critical ecosystems of the world. The Mediterranean has been intensively studied since the Antiquity, yet foundations underlying fish diversity patterns have been overlooked. In this study, as a first step, we studied fish diversity patterns in the Mediterranean and their determinants. Towards this objective, we built the first comprehensive database on the spatial distributions of the 619 Mediterranean fish species. We then carried out spatial analyses in order to assess the relative contribution of historical and geometric contingencies as well as environmental influences in shaping fish...

Diversity and biogeography of neotropical bamboos (Poaceae: Bambusoideae) Acta Botanica
Clark,Lynn G.
The present paper analyses the distribution of bamboos in New World. For convenience, bamboos are divided into two broad groups, the woody bamboos and the herbaceous bamboos. These categories do not necessarily reflect phylogenetic relationships among bamboo groups. The Bambuseae includes all of the woody bamboos and is probably monophyletic, whereas the herbaceous bamboos are classified into eight tribes. In the New World (including underscribed taxa), 45-46 genera and approximately 515 species are represented; only two genera: Arundinaria and Streptogyna are not exclusively neotropical. The area of greatest endemism and diversity is the humid coastal forests of Bahia, Brazil. 22 genera have been found in this relatively small area, representing 48% of...
