Two Androdioecious and One Dioecious New Species of Pristionchus (Nematoda: Diplogastridae): New Reference Points for the Evolution of Reproductive Mode
Journal of Nematology 45(3):172–194. 2013. Ó The Society of Nematologists 2013. Two Androdioecious and One Dioecious New Species of Pristionchus (Nematoda: Diplogastridae): New Reference Points for the Evolution of Reproductive Mode 1,y 2,y 2 2 2 NATSUMI KANZAKI, ERIK J. RAGSDALE, MATTHIAS HERRMANN, VLADISLAV SUSOY, RALF J. SOMMER Abstract: Rhabditid nematodes are one of a few animal taxa in which androdioecious reproduction, involving hermaphrodites and males, is found. In the genus Pristionchus, several cases of androdioecy are known, including the model species P. pacificus. A comprehensive understanding of the evolution of reproductive mode depends on dense taxon sampling and careful morpho- logical and phylogenetic reconstruction. In this article, two new androdioecious species, P. boliviae n. sp. and P. mayeri n. sp., and one gonochoristic outgroup, P. atlanticus n. sp., are described on morphological, molecular, and biological evidence. Their phylogenetic relationships are inferred from 26 ribosomal protein genes and a partial SSU rRNA gene. Based on current representation, the new androdioecious species are sister taxa, indicating either speciation from an androdioecious ancestor or rapid convergent evolution in closely related species. Male sexual characters distinguish the new species, and new characters for six closely related Pristionchus species are presented. Male papillae are unusually variable in P. boliviae n. sp. and P. mayeri n. sp., consistent with the predictions of ‘‘selfing syndrome.’’ Description and phylogeny of new androdioecious species, supported by fuller outgroup representation, es- tablish new reference points for mechanistic studies in the Pristionchus system by expanding its comparative context. Key words: gonochorism, hermaphroditism, morphology, P. boliviae n. -

Treat ABSTRACT-The isopod Aega monophthalma Johnston 1834 is reported for the first time from the tropical western Atlantic at Cay Sal Bank, Bahamas. The previously known distribution included the eastern and northern Atlantic. An adult male specimen of Aega monophthalma Johnston 1834 was obtained from a depth of 460 m at Cay Sal Bank, Bahamas, in May 1978. Prior to 1900, this species had been reported from Iceland, the Shetland Islands, Britain and Norway (Barnard, 1914). In 1901 a juvenile male specimen was discovered in deep waters off the South African coast (Barnard, 1914); subsequently, the species was reported from Denmark and Sweden (Stephensen, 1948). -

Based on carapace features, this taxon is placed in the subfamily Actaeinae, family Xanthidae MacLeay, 1838. Species attributed to this genus are known from Eocene reef environments in Europe. Preservation of crustacean remains in this kind of environment is very rare, and it could explain scarcity of specimens of this genus. For the fi rst time, pictures of types of this genus described during the XIX century and the fi rst decades of the XX century are presented. A study of recently collected specimens from the Eocene of Veneto (Italy) allows to clarify relationships between Phlyctenodes krenneri Lörenthey, 1898 and P. dalpiazi Fabiani, 1911. Presence of P. tuberculosus Milne Edwards, 1862 among the new material is documented. The other known species of this genus, P. hantkeni Lörenthey, 1898 is placed in Pseudophlyctenodes new genus on the basis of differences in morphological features. Key words: Crustacea, Decapoda, Phlyctenodes, systematic review, Eocene, Italy. RESUMEN Se presenta una revisión sistemática del género de cangrejo Phlyctenodes Milne Edwards, 1862.

Effect of Feed on the Growth and Survival of Long Eyed Swimming
Soundarapandian et al., 2:3 http://dx.doi.org/10.4172/scientificreports681 Open Access Open Access Scientific Reports Scientific Reports Research Article OpenOpen Access Access Effect of Feed on the Growth and Survival of Long Eyed Swimming Crab Podophthalmus vigil Fabricius (Crustacea: Decapoda) Soundarapandian P1*, Ravichandran S2 and Varadharajan D1 1Faculty of Marine Sciences, Centre of Advanced Study in Marine Biology, Annamalai University, Tamil Nadu, India 2Department of Zoology, Government Arts College, Kumbakonam, Tamil Nadu, India Abstract Food is considered to be the most potent factor affecting growth. Attempts to develop diets for culture of crabs have resulted in a variety of feeds. The absence of suitable feed either pellet or live food which can promote growth and survival is considered to be the most important lacuna in cultivation of crabs. So searching of economically viable feed to optimize the growth and survival in crabs are very much essential. In the present study the weight gain was higher in the crabs offered with Acetes sp. (86 g) followed by clam meat fed animals (47 g). The crabs fed with minimum amount of Acetes sp. (152 g) and maximum of clam meat (182 g). The FCR value was better in Acetes sp. (1.8) fed animal rather than clam meat fed animals (3.8). The survival rate was higher in Acetes sp. fed animals (92%) and lowest survival (72%) was observed in animals fed with clam meat. The survival was reasonable for both the feeds. But higher survival rate was reported in the animals fed with Acetes sp. than that of clam meat. -

This species was first collected off Israel in 1961 and is now common along the Levantine coast. Recently a second alien xanthid species, Actaea savignii (H. Milne Edwards, 1834), was found off Israel and Turkey. A single adult specimen was collected in Haifa Bay in 2010, and two specimens were captured off Mersin, Turkey in 2011. Repeatedly reported from the Suez Canal since 1924, the record of the Levantine populations of A. savignii is a testament to the ongoing Erythraean invasion of the Mediterranean Sea. -
Selection and Maintenance of Androdioecy in Caenorhabditis Elegans
Copyright 2002 by the Genetics Society of America Selection and Maintenance of Androdioecy in Caenorhabditis elegans Andrew D. Stewart1 and Patrick C. Phillips2 Department of Biology, University of Texas, Arlington, Texas 76019-0498 Manuscript received September 27, 2001 Accepted for publication December 14, 2001 ABSTRACT Caenorhabditis elegans is an androdioecious nematode composed of selfing hermaphrodites and rare males. A model of male maintenance demonstrates that selfing rates in hermaphrodites cannot be too high or else the frequency of males will be driven down to the rate of spontaneous nondisjunction of the X chromosome. After their outcrossing ability is assessed, males are found to skirt the frequency range in which they would be maintained. When male maintenance is directly assessed by elevating male frequency and observing the frequency change through time, males are gradually eliminated from the population. Males, therefore, appear to reproduce at a rate just below that necessary for them to be maintained. Populations polymorphic for a mutation (fog-2) that effectively changes hermaphrodites into females demonstrate that there is strong selection against dioecy. Factors such as variation in male mating ability and inbreeding depression could potentially lead to the long-term maintenance of males. NDRODIOECY is a sexual system composed of males the offspring to compensate (Lloyd 1975; Charles- A and hermaphrodites.

Chapter 51. Biological Communities on Seamounts and Other Submarine Features Potentially Threatened by Disturbance
Chapter 51. Biological Communities on Seamounts and Other Submarine Features Potentially Threatened by Disturbance Contributors: J. Anthony Koslow, Peter Auster, Odd Aksel Bergstad, J. Murray Roberts, Alex Rogers, Michael Vecchione, Peter Harris, Jake Rice, Patricio Bernal (Co-Lead members) 1. Physical, chemical, and ecological characteristics 1.1 Seamounts Seamounts are predominantly submerged volcanoes, mostly extinct, rising hundreds to thousands of metres above the surrounding seafloor. Some also arise through tectonic uplift. The conventional geological definition includes only features greater than 1000 m in height, with the term “knoll” often used to refer to features 100 – 1000 m in height (Yesson et al., 2011). However, seamounts and knolls do not appear to differ much ecologically, and human activity, such as fishing, focuses on both. We therefore include here all such features with heights > 100 m. Only 6.5 per cent of the deep seafloor has been mapped, so the global number of seamounts must be estimated, usually from a combination of satellite altimetry and multibeam data as well as extrapolation based on size-frequency relationships of seamounts for smaller features. Estimates have varied widely as a result of differences in methodologies as well as changes in the resolution of data. Yesson et al. (2011) identified 33,452 seamount and guyot features > 1000 m in height and 138,412 knolls (100 – 1000 m), whereas Harris et al. (2014) identified 10,234 seamount and guyot features, based on a stricter definition that restricted seamounts to conical forms. Estimates of total abundance range to >100,000 seamounts and to 25 million for features > 100 m in height (Smith 1991; Wessel et al., 2010).
