India, Japan and China to Java and Sulawesi (Indonesia) Being phytophagous they are more likely to arrive on and in damp temperate and tropical eastern North America plants and food; some become serious agricultural pests south to Colombia; they are also recorded as introduced (Runham and Hunter, 1970; Thomé, 1993; Robinson, in Hawaii (Pilsbry, 1948; Cowie, 1997; Wiktor et al., 1999).

Subjects identified by: Chan Sow-Yan. Location, date and time: Singapore Island, Mei Hwan Drive; 11 January 2019; late afternoon. Habitat: Urban parkland. In playground, at the base of a tembusu tree. Observer: Chan Sow-Yan. Observation: At least three examples were seen exposed among leaf debris in the shade of a tembusu tree after light rain. One example, of about 10.2 mm shell length, is illustrated in Fig. 1. They were found together with the morphologically similar Subulina octona (Fig. 2). Fig. 1.

Photographs by Chan Sow Yan Remarks: Striosubulina striatella was first recorded in Singapore as ‘? Subulina striatella’ with doubt by Maassen (2001). The species was described as Helix striatella from Principe Island in the Gulf of Guinea, West Africa by Rang (1831). It was recently introduced to East Africa (Rowson et al., 2010) among many other places. This snail is apparently not native to Singapore, and likely to have been introduced there earlier than Maassen’s record in 2001. It seems to have escaped detection due to its strong resemblance in both appearance and size to the locally abundant con-familial Subulina octona. Although both species have a similar truncated columella, Striosubulina striatella can be distinguished by its fine axial sculpture (if observed under a X10 hand lens), as well as a faint dark area on its eye stalks (see Fig.

Walker Lawrence L. Woolbright Joseph M. Wunderle, Jr. Xiaoming Zou DOI:10.1093/acprof:osobl/9780195334692.003.0005 Abstract and Keywords This chapter describes the responses of the organisms, communities, and ecosystems to the variety of disturbances by utilizing the conceptual model discussed in Chapter 2. It also dwells on the concepts of residuals, legacies, and ecological space in the understanding of disturbances such as background treefalls, hurricanes, floods, drought, landslides, and other human-induced disturbances. Finally, it outlines the variations caused by disturbances and the interactions among these disturbances. Keywords: variety of disturbances, conceptual model, residuals, legacies, ecological space, background treefalls Key Points • Background treefall gaps (not caused by hurricanes) are filled with plant regrowth as in other tropical forests. There is limited response by animals to treefall gaps, probably because background treefall gaps are relatively less important in these forests, which are dominated by chronic, widespread hurricane effects. • Despite substantial effects on trees, the tree species composition changed little in the tabonuco forest after two recent hurricanes. • Animal species show various responses to the changes in forest architecture and food resources caused by hurricanes. Bird species tend to be plastic in habitat and dietary requirements, probably due to the large changes in forest structure caused by hurricanes and regrowth, which require birds to change their foraging locations and diets.

  • An Annotated List of the Non-Marine Mollusca of Britain and Ireland
    JOURNAL OF CONCHOLOGY (2005), VOL.38, NO .6 607 AN ANNOTATED LIST OF THE NON-MARINE MOLLUSCA OF BRITAIN AND IRELAND ROY ANDERSON1 Abstract An updated nomenclatural list of the non-marine Mollusca of the Britain and Ireland is provided. This updates all previous lists and revises nomenclature and classification in the context of recent changes and of new European lists, including the Clecom List. Cases are made for the usage of names in the List by means of annotations. The List will provide a basis for the future census and cataloguing of the fauna of Britain and Ireland. Key words Taxonomic, list, nomenclature, non-marine, Mollusca, Britain, Ireland, annotated. INTRODUCTION There has been a need for some time to modernise the list of non-marine Mollusca for Britain and Ireland, a subject last visited in this journal in 1976 (Waldén 1976; Kerney 1976). Many of the changes that have appeared in the literature since then are contentious and Kerney (1999) chose not to incorporate many of these into the latest atlas of non-marine Mollusca of Britain and Ireland. A new European List, the Clecom List (Falkner et al. 2001) has now appeared and it seems appropriate to examine in more detail constituent changes which might affect the British and Irish faunas. This is given additional urgency by the inception of a new census of the molluscs of Britain and Ireland by the Conchological Society. Recorders in the Society are aware of many of the proposed changes but unable to implement them without general agreement. In addition, many field malacologists make use of the recording package RECORDER, a recent form of which has been developed jointly by JNCC and the National Biodiversity Network in the United Kingdom.

Departementd'Entomologie, Parc Botanique et Zoologiquede Tsimbazaza, Antananarivo 101, MADAGASCAR ABSTRACT.-Madagascar's known native land-snail faunais currently classifiedinto 540 species(97% endemic) in 68 genera (29% endemic)in 25 families (0% endemic). Recent survey work throughout the island may as much as double this number of species and should provide, for the first time, adequate material and distributional data for robust cladistic and biogeographic analyses. Preliminary analysisof existing cladograms and range maps suggestsareas of endenlism with recurrent patterns of vicariance. Which of the many Madagascan taxa will yieldthe most biogeographic information perunit of effort? Based on the criteria of species number, nzonophyly, vagility, character accessibility, and Gondwanan areas of endemism, the best candidates are (a) acavoids (giant, k-selected, (( bird's-egg snails D), (b) Boucardicus (minute, top-shaped shells with flamboyant apertures), (c) charopids (minute, discoid shells with complex microsculptures), and (d) streptaxids (small-to-medium-sized, white-shelled, high-spired carnivores). KEY-W0RDS.- Land-snail, Madagascar, Informative, Biogeography RESUME.- La faune connueà l'heure actuelle des escargots terrestres de Madagascar peut être classée dans 540 espèces (97% endémiques), 68 genres (29% endémiques) et 25 familles(0% endémiques). Un récent travail d'inventaire réalisé dans l'ensemble l'îlede pourra amener à doubler le nombre d'espèces et devra fournir pour la première fois un matériel et des données adéquates sur la distribution des espèces permettant des analyses cladistiques et biogéographiques robustes.

Understanding the Remarkable Biodiversity of Príncipe Island – Scientific Report 1 www.fundacaoprincipe.org Summary Principe is home to a diversity of unique fauna and flora including globally threatened species such as the Critically Endangered Príncipe Thrush (Turdus xanthorhynchus) and the Vulnerable Obô Snail (Archachatina bicarinata). The implementation of conservation plans in Príncipe has previously been impeded by a lack of capacity and resources. Our project – Understanding the Remarkable Biodiversity of Prícipe Island – has built local capacity and implemented priority actions from existing conservation plans through the completion of a series of biological and social field surveys. These included an island wide survey of bird species using a point-count method; camera trap and nesting surveys to examine threats to the Príncipe Thrush; sampling of terrestrial molluscs at 10 sites across the island; & a questionnaire based survey of 14 communities to examine forest resource use and knowledge of the Obô Snail. Key findings included: An inventory of 32 bird species, with distribution models produced for 20 of these Confirmation of a March-July breeding period for the Príncipe thrush Camera trap images of non-native mammal species within the Parque Natural do Principe, including feral cats, dogs, African civets, Mona monkeys, and black rats.

David T. HOLYOAK1, Geraldine A. HOLYOAK1, Ricardo F. de LIMA2,3, Martina PANISI2 and Frazer SINCLAIR3,4 Recibidio el ... ABSTRACT Seven species of terrestrial Gastropoda are newly described from the island of São Tomé and six more from the island of Príncipe. The genera involved are Chondrocyclus (Cyclophoridae), Maizania and Thomeomaizania (Maizaniidae), Pseudoveronicella (Veronicellidae), Nothapalus (Achatinidae: subfamily undet.), Gulella and Streptostele (Streptaxidae), Truncatellina (Truncatellinidae), Afroconulus (Euconulidae), Principicochlea gen. nov., Principotrochoidea gen. nov., Thomithapsia gen. nov. and Thomitrochoidea gen. nov. (Urocyclidae). Most of these are from natural forest habitats and are likely to be single- island endemics. Apothapsia gen. nov. (Helicarionidae) is also described to accommodate two previously known species. Additional new island records are of ten species on São Tomé, one on Príncipe alone and two more on both islands. These include six species of "microgastropods" with wider ranges in tropical Africa that are likely to be hitherto overlooked parts of the indigenous fauna and six anthropogenic introductions; Pseudopeas crossei previously known only from Príncipe and Bioko is newly recorded on São Tomé.
