Article
Limnadia lenticularis, a well-known representative of the Conchostraca Spinicaudata in Europe, was generally accepted as a parthenogenetic species. During an intensive faunistic study of Austrian conchostracans, four of a total of 364 collected L. lenticularis specimens were males. This paper provides the collection localities, compares the sex rat...
Article
Recent reports of occasional males in Austrian populations of Triops cancriformis have promoted interest in an analysis of the ultrastructure of the male gonad. It appears as a double thick and well-defined tubular structure running along the midgut, inside the hemocoel. It is composed of two portions: the wall and the lumen. The former is made up...
Article
The cyst deposition behaviour of Streptocephalus torvicornis is described as the first documented case of active cyst deposition in Anostraca. The functional morphology of the brood pouch of S. torvicornis is described and illustrated using both Light Microscopy and Scanning Electron Microscopy. The brood pouch is an elongated tube-like structure w...

This chapter discusses evolution education and the acceptance of evolution in Germany, Austria, Switzerland, South Tyrol, and Luxembourg. Ernst Haeckel first introduced Darwin’s concepts to a broad public in Germany. His interpretation of evolution was more teleological, hierarchical, and definitely more anti-religious than intended by Darwin. Late...

Paranormal belief correlates positively with belief in alternative medicine. Bio-medical knowledge correlated negatively with belief in alternative medicine in high school students, but not in medical students. Medical students showed lower belief in alternative medicine and the paranormal than high school students.

The Balkan Peninsula is a biodiversity hotspot and hosts numerous mountain lakes, which offer a refuge for a multitude of species. However, previous pristine habitats have been deeply affected by anthropogenic change, such as non-native fish introductions, which calls for multi-species considerations in the last remaining unaltered habitats. We car...

Large branchiopods are one of the most iconic species groups in temporary pools. Due to their specific biology and massive habitat degradation, they are one of the most threatened freshwater species groups. In this study, we used a unique dataset on the distribution of large branchiopods on a national scale (Austria), data on the distribution of te...

Rediscovery of Limnadia lenticularis in the Burgenland province: occurrence of large branchiopods in the Lower Leitha valley. A new population of large branchiopods was encountered in the municipal areas of Nickelsdorf and Zurndorf (Burgenland, Austria) in 2014. Five species were documented: the fairy shrimp Branchipus schaefferi, the tadpole shrim...

Temporary water bodies and their conservational significance. Temporary ponds are important, but often neglected habitats for many endangered species. Size and hydroperiod determine the occurrence of aquatic species, e.g. mosquito larvae, large branchiopods and amphibians. Sixteen species of the so-called primeval shrimps (large branchiopods) were...

The present study is the first to investigate the relationships between a multiple set of paranormal beliefs and the acceptance of evolution, creationism, and intelligent design, respectively, in Europe. Using a questionnaire, 2,129 students at secondary schools in Vienna (Austria) answered the 26 statements of the Revised Paranormal Belief Scale (...

In a blind and randomised study, early postlarval stages of the tadpole shrimp Triops cancriformis, the fairy shrimp Branchipus schaefferi, and the clam shrimp Leptestheria dahalacensis were exposed to different concentrations of a commonly available Bti suspension, equivalent to 0, 4.5 (recommended treatment concentration), 45, 450, and 4500 AA/l....

Six different pH ranges were tested for the hatching rate of Triops cancriformis cysts. Cumulative hatching numbers approach to approximately 50% of cysts. The highest hatching rates, co-occurring with the shortest hatching times, were recorded in the neutral range. No hatching took place at pH values 9 and above. This corresponds with the most fre...

Branchiopods reproductive mechanisms range from gonochorism to unisexuality, passing through an- drodioecy. In order to contribute to still lacking or controversial basic knowledges, we analyzed the karyotype of the main Italian taxa: the Notostracan living fossils Triops cancriformis (parthenogenetic) and Lepidurus apus lubbocki (bisexual), and th...

With 16 species belonging to 14 genera, branchiopod diversity in Austria is very high which is mainly due to the biogeographical situation of the country: the floodplains of the Morava river, as well as the Neusiedler See – Seewinkel region show a strong Pannonian influence. Species with holarctic and European distribution also occur in Austria, as...

This paper presents a SEM documentation of the larval development of the two most abundant Austrian conchostracan species, Imnadia yeyetta (Limnadiidae) and Leptestheria dahalacensis (Leptestheriidae). As in several previously examined spinicaudatan species, five larval stages were documented: Nauplius 1, Nauplius 2, Metanauplius, Peltatulus, and H...

For the first time, Anostraca, Notostraca and Conchostraca (Laevicaudata, Spinicaudata) will be listed in the Austrian Red Data Book of Endangered Species. According to the 1999 IUCN draft criteria, eight out of 15 large branchiopod species recorded be-tween 1994 and 1999 are considered as critically en-dangered, three of which (Chirocephalus shadi...

Red lists are among the most important and popular instruments of environmental control and nature conservation. However, owing to the vagueness of red list threat category definitions and the lack of a standardised assessment methodology, they have come under scrutiny. To improve risk assessment and threat categorisation, the IUCN initiated a symp...

In Austria, the distribution of Anostraca, Notostraca, and Conchostraca is mainly confined to the floodplains of the rivers Morava and Danube, and the shallow alkaline pans of the Seewinkel region in Burgenland province. Occasionally, large branchiopods can also be found in rain pools of the eastern and central Austrian lowlands, where topography a...

According to recent literature, five of the six known Austrian conchostracan species are extinct. However, interim results of a current study on large freshwater branchiopods in Austria show that five species still occur at a restricted number of sites in the Pannonian region of Lower Austria.

Reproductive mechanisms of branchiopods range from gonochorism to unisexuality, passing through androdioecy. We found and described males in a well known species thought to be exclusively parthenogenetic (Limnadia lenticularis), and we examined the gonads of males in a common branchiopod species with occasional males (Triops cancriformis).
Project
In Austria there are 16 species of large branchiopods. All of them can be found in astatic water bodies, and little is known about their distribution. Due to their highly endangered conservation status, a better understanding about the distribution is needed for planning conservat measures.
