The present geological period has more species than any other, yet the current rate of extinction of species is greater now than at any time in the past. Ecosystems and communities are being degraded and destroyed, and species are being driven to extinction. The species that persist are losing genetic variation as the number of individuals in populations shrinks, unique populations and subspecies are destroyed, and remaining populations become increasingly isolated from one another. The cause of this loss of biological diversity at all levels is the range of human activity that alters and destroys natural habitats to suit human needs.” (Primack, 2002). CapeNature launched its State of Biodiversity Programme (SoBP) to assess and monitor the state of biodiversity in the Western Cape in 1999. This programme delivered its first report in 2002 and these reports are updated every five years. The current report (2007) reports on the changes to the state of vertebrate biodiversity and land under conservation usage. -
Contribution to the Lepidoptera Fauna of the Madeira Islands Part 2
Beitr. Ent. Keltern ISSN 0005 - 805X 51 (2001) 1 S. 161 - 213 14.09.2001 Contribution to the Lepidoptera fauna of the Madeira Islands Part 2. Tineidae, Acrolepiidae, Epermeniidae With 127 figures Reinhard Gaedike and Ole Karsholt Summary A review of three families Tineidae, Epermeniidae and Acrolepiidae in the Madeira Islands is given. Three new species: Monopis henderickxi sp. n. (Tineidae), Acrolepiopsis mauli sp. n. and A. infundibulosa sp. n. (Acrolepiidae) are described, and two new combinations in the Tineidae: Ceratobia oxymora (MEYRICK) comb. n. and Monopis barbarosi (KOÇAK) comb. n. are listed. Trichophaga robinsoni nom. n. is proposed as a replacement name for the preoccupied T. abrkptella (WOLLASTON, 1858). The first record from Madeira of the family Acrolepiidae (with Acrolepiopsis vesperella (ZELLER) and the two above mentioned new species) is presented, and three species of Tineidae: Stenoptinea yaneimarmorella (MILLIÈRE), Ceratobia oxymora (MEY RICK) and Trichophaga tapetgella (LINNAEUS) are reported as new to the fauna of Madeira. The Madeiran records given for Tsychoidesfilicivora (MEYRICK) are the first records of this species outside the British Isles. Tineapellionella LINNAEUS, Monopis laevigella (DENIS & SCHIFFERMULLER) and M. imella (HÜBNER) are dele ted from the list of Lepidoptera found in Madeira. All species and their genitalia are figured, and informa tion on bionomy is presented. Zusammenfassung Es wird eine Übersicht über die drei Familien Tineidae, Epermeniidae und Acrolepiidae auf den Madeira Inseln gegeben. Die drei neuen Arten Monopis henderickxi sp. n. (Tineidae), Acrolepiopsis mauli sp. n. und A. infundibulosa sp. n. (Acrolepiidae) werden beschrieben, zwei neue Kombinationen bei den Tineidae: Cerato bia oxymora (MEYRICK) comb. -

POMORY 2007 Department of Biology, University of West Florida, 11000 University Parkway, Pensacola, FL 32514, USA. [email protected] ABSTRACT A key is given for 85 species of ophiuroids from the Gulf of Mexico and Caribbean Sea covering a depth range from the intertidal down to 30 m. Figures highlighting important anatomical features associated with couplets in the key are provided. 2 INTRODUCTION The Caribbean region is one of the major coral reef zoogeographic provinces and a region of intensive human use of marine resources for tourism and fisheries (Aide and Grau, 2004). With the world-wide decline of coral reefs, and deterioration of shallow-water marine habitats in general, ecological and biodiversity studies have become more important than ever before (Bellwood et al., 2004). Ecological and biodiversity studies require identification of collected specimens, often by biologists not specializing in taxonomy, and therefore identification guides easily accessible to a diversity of biologists are necessary. -

Abstract Additions, deletions and corrections are made to the Irish checklist of butterflies and moths (Lepidoptera). Elachista biatomella (Stainton, 1848) is added to the Irish list. The total number of confirmed Irish species of Lepidoptera now stands at 1480. Key words: Lepidoptera, additions, deletions, corrections, Irish list, Elachista biatomella Introduction Bond, Nash and O’Connor (2006) provided a checklist of the Irish Lepidoptera. Since its publication, many new discoveries have been made and are reported here. In addition, several deletions have been made. A concise and updated checklist is provided. The following abbreviations are used in the text: BM(NH) – The Natural History Museum, London; NMINH – National Museum of Ireland, Natural History, Dublin. The total number of confirmed Irish species now stands at 1480, an addition of 68 since Bond et al. (2006). Taxonomic arrangement As a result of recent systematic research, it has been necessary to replace the arrangement familiar to British and Irish Lepidopterists by the Fauna Europaea [FE] system used by Karsholt 60 Bulletin of the Irish Biogeographical Society No. 36 (2012) and Razowski, which is widely used in continental Europe.
