Wilhelm August Wenz
Wilhelm August Wenz (21 October 1886 – 12 September 1945) was a German malacologist, born in Frankfurt am Main. He is the author of the 7-part Gastropoda section of ''Handbuch der Paläozoologie'' (1938-1944), a very important review that described all known fossil genera. Only a few copies of this rare work survive: almost the entire stock of later editions was destroyed during the Second World War. Bibliography (incomplete) * Fischer K. & Wenz W. A.

Paläontologische Zeitschrift
''PalZ'' (formerly ''Paläontologische Zeitschrift'') is an international, peer-reviewed periodical focused on palaeontology and published by the palaeontological society of Germany ( Paläontologische Gesellschaft). The first issue was released in 1914. Until 1998 the journal was issued semiannually. From there on 4 issues were published each year. From 2009 on the periodical is printed and distributed by the Axel Springer AG. PalZ publishes articles in the field of vertebrate palaeontology, invertebrate palaeontology Invertebrate paleontology (also spelled invertebrate palaeontology) is sometimes described as invertebrate paleozoology or invertebrate paleobiology. Whether it is considered to be a subfield of paleontology, paleozoology, or paleobiology, this d ..., micropalaeontology and ichnology to approximately the same extent. While the publication language was predominantly German in most of the 20th century, it successively shifted to English since the 1980s. References ...

Malacologist
Malacology is the branch of invertebrate zoology that deals with the study of the Mollusca (mollusks or molluscs), the second-largest phylum of animals in terms of described species after the arthropods. Mollusks include snails and slugs, clams, and cephalopods, along with numerous other kinds, many of which have shells. One division of malacology, conchology, is devoted to the study of mollusk shells. Malacology derives . Fields within malacological research include taxonomy, ecology Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps wi ... and evolution. Applied malacology studies medical, veterinary, and agricultural applications; for example, mollusks as vectors of disease, as in schistosomiasis. Archaeology employs malacology to understand the evolution of the climate, the biota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autobiography
An autobiography, sometimes informally called an autobio, is a self-written account of one's own life. It is a form of biography. Definition The word "autobiography" was first used deprecatingly by William Taylor in 1797 in the English periodical ''The Monthly Review'', when he suggested the word as a hybrid, but condemned it as "pedantic". However, its next recorded use was in its present sense, by Robert Southey in 1809. Despite only being named early in the nineteenth century, first-person autobiographical writing originates in antiquity. Roy Pascal differentiates autobiography from the periodic self-reflective mode of journal or diary writing by noting that " utobiographyis a review of a life from a particular moment in time, while the diary, however reflective it may be, moves through a series of moments in time". Autobiography thus takes stock of the autobiographer's life from the moment of composition. While biographers generally rely on a wide variety of documents an ...

Vertigo Geyeri
''Vertigo geyeri'' is a species of minute air-breathing land snail, a terrestrial pulmonate gastropod mollusc or micromollusc in the family Vertiginidae, the whorl snails. The specific name ''geyeri'' is in honor of German zoologist David Geyer (1855–1932). Description The egg-shaped-oval shell measures just . in length and in width. There are up to five whorls with deep seams. The aperture has four small protrusions (called "teeth") (on parietal one columellar and two palatal), it can also have fewer teeth. The colour of the shell is reddish-brown and the surface is shiny. The shell has regular growth striations and is almost smooth. Habitat This species lives in constantly wet, calcareous flush-fens that are fed by tufa-depositing springs. In the British Isles (Ireland and United Kingdom) it often lives in association with black bog-rush ''Schoenus nigricans'' and yellow sedge ''Carex viridula'', in dense short grasses and sedges with little ''Sphagnum'' moss.

Xerocrassa Geyeri
''Xerocrassa geyeri'' but as anomaly it was found also in 370 m above sea level in Mont Vertoux. ''Xerocrassa geyeri'' is hermaphrodite, hermaphroditic species and fertilisation is obligately outcrossing. The main reproduction period is from March to June and from September to October (according to the table values). It lays usually less than 10 uncalcified egss, but sometimes more (according to the table values). Juveniles are hatching from eggs in less than two weeks (according to the table values). They reach sexual maturity in one year and longevity of this species is 1–2 years. ''Xerocrassa geyeri'' feeds on dead plants, but rarely also on living plants, epilithic lichens and on algae. Its active Biological dispersal, dispersal capacity is about 3 m during its one-year lifetime. Its competitor may be ''Candidula unifasciata''.
