Molecular Phylogenetic Evidence That the Chinese Viviparid Genus Margarya (Gastropoda: Viviparidae) Is Polyphyletic

The molecular phylogeny based on the combined dataset indicates that Margarya is polyphyletic, as two of the three well-supported clades containing species of Margarya also comprise species from other viviparid genera. In one clade, sequences of four species of Margarya even cluster indiscriminately with those of two species of Cipangopaludina, indi- cating that the current state of Asian viviparid taxonomy needs to be revised. Additionally, these data suggest that shell evolution in viviparids is complex, as even the large and strongly sculptured shells of Margarya, which are outstanding among Asian viviparids, can apparently be easily converted to simple smooth shells. -

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. -

Gastropoda, Prosobranchia)
BASTERIA, 64: 151-163, 2000 The genus Alzoniella Giusti & Bodon, 1984, in France. 1 West European Hydrobiidae, 9 (Gastropoda, Prosobranchia) Hans+D. Boeters Karneidstrasse 8, D 81545 Munchen, Germany In France the genusAlzoniella Giusti & Bodon, 1984, is represented with two subgenera, viz. its nominate subgenus and Navarriella subgen. nov. The nominate subgenus comprises six three species, ofwhich are described as viz. A. haicabia A. new, (A.) spec. nov., (A.) junqua spec. A. nov. and A. (A.) provincialis spec. nov., next to (A.) navarrensis Boeters, 1999, A. (A.) perrisii and A. (Dupuy, 1851) (A.) pyrenaica (Boeters, 1983). The new subgenus is proposed for A. (Navarriella) elliptica (Paladilhe, 1874) only. A. (A.) perrisii (Dupuy, 1851) [Hydrobia], the first of this became known from is redefined and species genus that France, described here with two viz. A. and A. subspecies, (A.) p. perrisii (A.) p. irubensis subspec. nov. Key words: Gastropoda, Prosobranchia, Hydrobiidae, Alzoniella (Alzoniella) and Alzoniella (Navarriella), France. INTRODUCTION Giusti & Bodon (1984: 169) described Alzoniella for three eyeless, subterranean, hy- drobiid species from Italy, that might have evolved from small populations that locally survived the Quaternary glaciations. It turned out that Alzoniella is also represented in where mountain inhabited France, regions are that have partially been subject to gla- ciations, viz. the Pyrenees and the MediterraneanAlps. In these regions too, populations ofancestral have Alzoniella might survived locally by invading subterranean waters. This development apparently went less far than in for example Bythiospeum Bourguignat, 1882, andMoitessieria Bourguignat, 1863. Species of these two genera, which are eyeless stygobionts, occur not only in karstic waters, but also in the interstitium and in subter- ranean waters bordering river valleys such as that of the Rhone river (Boeters & Miiller be found 1992). -
Using Spatially Explicit Call Data of Anhydrophryne Ngongoniensis to Guide Conservation Actions
Using spatially explicit call data of Anhydrophryne ngongoniensis to guide conservation actions M Trenor orcid.org/0000-0002-0682-2262 Dissertation submitted in fulfilment of the requirements for the Masters degree in Zoology at the North-West University Supervisor: Prof C Weldon Co-supervisor: Dr J Tarrant Graduation May 2018 25747339 Abstract It’s been barely 25 years since the Mistbelt Chirping Frog (Anhydrophryne ngongoniensis) was discovered. This secretive amphibian occurs only in the so-called mistbelt grasslands and montane forest patches of south-central KwaZulu-Natal, South Africa and is restricted to an area of occupancy of just 12 square kilometers. This species’ habitat is severely fragmented due to afforestation and agriculture and only two of the remaining populations are formally protected. The species occurs mostly on fragmented grassland patches on forestry land, and any conservation strategies should include the management practices for the landowners. Updated density estimates and insight into habitat utilization are needed to proceed with conservation strategy for the species. Like many other frogs, this species is cryptic in its behaviour, making mark-recapture surveys prohibitively challenging. Audio transects have been used previously, but are dependent on surveyor’s’ experience, hindering standardization. Using automated recorders, in a spatially explicit array with GPS synchronization, one can confidently estimate the density of calling males and reveal the estimated locations of calling males, thus providing insight into their occupancy. We surveyed nine historic sites and detected the species at five of the sites in either isolated grassland patches or indigenous Afromontane forest. We successfully employed the spatially explicit catch recapture (SECR) method at three of the sites using Wildlife Acoustics™ Song Meters with extended microphones in an array. -

Ein Beitrag Zur Anatomie Von Bythiospeum Tschapecki (CLESSIN, 1878) (Moll., Gastropoda, Prosobranchia)
©Landesmuseum Joanneum Graz, Austria, download unter www.biologiezentrum.at Mitt. Abt. Zool. Landesmus. Joanneum Heft 30 S. 79—82 Graz 1983 Ein Beitrag zur Anatomie von Bythiospeum tschapecki (CLESSIN, 1878) (Moll., Gastropoda, Prosobranchia) Von Peter L. REISCHÜTZ Mit 2 Abbildungen Eingelangt am 27. Mai 1983 Inhalt: Die Genitalmorphologie von Vitretta tschapecki CLESSIN, 1878 wurde erstmals untersucht und die Zugehörigkeit dieser Art zur Gattung Bythiospeum BOURGUIGNAT, 1882. festgestellt. Abstract: The genital morphology of Vitretta tschapecki CLESSIN, 1878 has been examined for the first time and this has proven that this species belongs to the genus Bythiospeum BOURGUIGNAT, 1882. Die Buchkogelhöhle bei St. Martin bei Graz ( = Bründlhöhle, Höhlenkat. Nr. 2793/1) ist locus typicus eines kaum bekannten stygobionten Süßwasser-Proso- branchiers: Vitrella tschapecki CLESSIN, 1878. Bei einer Exkursion mit Dr. E. KREISSL zum locus typicus konnten mehrere Exemplare dieser Art gesammelt und drei anatomisch untersucht werden. Die systematische Stellung der Art war bisher sehr unsicher, da die anatomischen Verhältnisse unbekannt waren. CLESSIN, 1878 beschrieb Vitrella tschapecki mit einem falschen Fundort (Sanriack in Kärnten). Dies wurde später korrigiert (CLESSIN, 1882 und 1887). BOURGUIGNAT, 1882 stellte diese Art zu seiner Gattung Bythiospeum, da Vitrella CLESSIN, 1877 synonym zu Vitrella SWAINSON, 1840 ist. WESTERLUND, 1886 stellte sie in die Gattung Paludinella L. PFEIFFER, 1841, GEYER, 1909 zur Gattung Lartetia BOURGUIGNAT, 1869, FUCHS, 1929 in die Gattung Paladilhiopsis PAVLOVIC, 1913. KLEMM, i960 betrachtete Paladilhiopsis als Untergattung von Paladilhia BOURGUIGNAT. Da die bisherige Gliederung nur auf konchyologischen Merkmalen beruhte (FUCHS, 1925 und 1929, MAHLER, 1949, STOJASPAL, 1978 und REISCHÜTZ, 1981 und 1983), sollte möglichst umfangreiches Material aus dem österreichischen Unter- suchungsgebiet untersucht werden.
