Die ersten Nachweise der Wasserassel Proasellus meridianus CRacovitza, 1919) (Crustacea, Isopoda Asellidae) im Einzugsgebiet der Ems KARL FRIEDRICH HERHAUS, Münster In Deutschland ist die von HENRY und MAGNIEZ (1970) revidierte Familie Asellida,e Sars, 1899, mit drei oberirdischen Arten vertreten. Die am weitesten verbreitete Art ist Asellus ( Asellus) aquaticus (L., 175 8); sie ist ein sibirisches Faunenelement, das sich postglazial nach Westen hin ausgebreitet hat (BrRSTEIN 1951; WILLIAMS 1962). Weitaus weniger häufig tritt die zweite Art, Proasellus coxalis (Dollfus, 1892), auf; diese im übrigen circummediterran verbreitete Art ist in Mittel europa mit der Unterart septentrionalis (Herbst, 1956) vertreten, die vermutlich erst in jüngster Zeit eingeschleppt worden ist (HERHAUS 1977). Am seltensten ist auf deutschem Boden die dritte Art, Proasellus meridianus (Racovitza, 1919). P. meridianus ist eine autochthon west europä,isch-atlantische Form (GRUNER 1965); in Deutschland wurde sie von STAMMER (1932) am linken Niederrhein nachgewiesen. Für die sichere Bestimmung der drei Arten ist die Untersuchung der Pleopoden II unter dem Binokular unerläßlich. -

The Mexican tetra (Astyanax mexicanus) has repeatedly colonized caves in the Sierra de El Abra and Sierra de Guatemala regions of north-east Mexico ~0.20–1 Mya, indicating an ability to adapt to the cave environment. The time frame for the evolution of these traits in any cave animal, however, is poorly understood. Astyanax mexicanus from the Río Grande in South Texas were brought to Central Texas beginning in the early 1900s and colonized underground environments. -

A large number of genera in the tropical fish family Characidae are incertae sedis. Cytogenetic analysis was made of four of these species: Astyanax eigenmanniorum, Deuterodon stigmaturus, Hyphessobrycon luetkenii, and H. anisitsi, collected from various hy- drographic basins: hydrographic system from Laguna dos Patos/RS, Tramandaí basin/RS and Tibagi River basin/PR. The first two species were collected in their type locality in the State of Rio Grande do Sul. The 2n = 48 karyotype was observed only in A. eigenmanniorum, while the other species had 2n = 50 chromosomes, with different karyotypic formulas. There was weak heterochromatin staining in the pericentro- meric region of A. eigenmanniorum, D. stigmaturus and H. luetkenni chromosomes. In H. anisitsi, heterochromatin appeared to be more abundant and distributed in the pericentromeric and terminal regions of the chromosomes; three pairs showed more evident heterochromatic blocks. There were multiple Ag-NORs in all populations, visualized by FISH with an 18S rDNA probe. While D. stigmaturus and H. luetkenii Genetics and Molecular Research 10 (4): 3596-3608 (2011) ©FUNPEC-RP www.funpecrp.com.br Karyotype diversity of an incertae sedis group in Characidae 3597 had conserved AgNOR, CMA3 and 18S rDNA sites, the other two spe- cies showed intra- and interindividual variation at these sites. -

Investigating the Genetic Basis of Altered Activity Profiles in the Blind
Investigating the genetic basis of altered activity profiles in the blind Mexican cavefish, Astyanax mexicanus A dissertation submitted to the Graduate School of the University of Cincinnati in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Biological Sciences of the McMicken College of Arts and Sciences by by Brian M. Carlson B.S. Biology, Xavier University, May 2010 Committee Chair: Dr. Joshua B. Gross June 2015 ABSTRACT Organisms that have evolved to exploit extreme ecological niches may alter or abandon survival strategies that no longer provide a benefit, or may even impose a cost, in the environment to which they have adapted. Cave environments are characterized by perpetual darkness, isolation and relatively constant temperature and humidity. Accordingly, cave-adapted species tend to converge on a suite of regressive and constructive morphological, physiological and behavioral alterations, including loss or reduction of eyes and pigmentation, increased locomotor activity and reduction or alteration of behavioral rhythmicity. The cave environment and the associated changes in locomotor behavior make species of cavefish prime natural models in which to examine the complex genetic architecture underlying these behavioral phenotypes. The principal goal of this dissertation was to investigate the genetic basis of altered locomotor activity patterns in the blind Mexican tetra, Astyanax mexicanus. Initially, a custom locomotor assay rig and experimental protocols were developed to assess, characterize and compare activity patterns in surface and Pachón cavefish. The results of these assays clarified differences between the morphotypes, provided evidence that Pachón cavefish retain a weakly-entrainable circadian oscillator with limited capacity to self-sustain entrained rhythms and suggested that patterns in spatial “tank usage” data may be the result of a positive masking effect in response to light stimulus in both morphotypes. -
Isopoda, Asellota) with Some Phylogenetic Considerations Concerning Asellota
Crustaceana 48 (2) 1985, E. J. Brill, Leiden A CONTRIBUTION TO THE GENERAL MORPHOLOGY OF PROTOJANIRIDAE (ISOPODA, ASELLOTA) WITH SOME PHYLOGENETIC CONSIDERATIONS CONCERNING ASELLOTA BY B. SKET Institut za biologijo, Univerza E. Kardelja v Ljubljani, p.p. 141, YU 61001 Ljubljana, Yugoslavia Since most representatives of the superfamily Gnathostenetroidoidea have been described only for "microtaxonomical" purposes, some important features and even peculiarities of the species and probably of the entire group have been overlooked. I took advantage of possessing a good sample of the comparatively very large representative, viz., Enckella lucei major Sket, 1982 (as well as some other species of the family Protojaniridae) to demonstrate some such features. Unfortunately, of the family Gnathostenetroididae I could study only specimens of an undescribed species from the Bahamas, while comparison with other representatives was possible only through illustrations. I abstained from comparing Enckella with the numerous and diverse Janiroidea, leaving this to a more versed student of that special group. I also abstained from discussing the remarkable idea about possible Asellotan nature of Microcerberidae (WageJe, J 980) which is anyway of little importance for the present subject. Cephalothorax ("head"). — With the exception of having two pairs of antennae, the Enckella's head bears greater resemblance to a prognathous in sect head than to an Asellid. The cephalic capsula is closed to a great extent, incorporating completely the first thoracomere. The capsula is closed and slightly sclerotised also behind the insertions of the maxillipeds, uniting them with the set of other mouth appendages. The clypeolabrum protrudes for wards, its inclination downwards is much less expressed than in most other groups of Isopoda. -

Traditionally, the purposefulness and relevance of a singer-songwriter were defined by something unique in their lyrical acumen, vocal skills and/or guitar or piano accompaniment. In the 1990s this paradigm was tested by the trend towards larger orchestrastion and towards electronic orchestration. In the 2000s it became harder and harder to give purpose and meaning to a body of work mostly relying on the message. Many singer-songwriters of the 2000s belonged to "Generation X" but sang and wrote for members of "Generation Y". Since "Generation Y" was inherently different from all the generations that had preceeded it, it was no surprise that the audience for these singer-songwriters declined. Since the members of "Generation X" were generally desperate to talk about themselves, it was not surprising that the number of such singer- songwriters increased. The net result was an odd disconnect between the musician and her or his target audience. The singer-songwriters of the 2000s generally sounded more "adult" because... they were. -

Subterranean Biology 26: 75–84. https://doi.org/10.3897/subtbiol.26.27097 Abstract The Sierra de El Abra is a long (120 km) and narrow (10 km) karstic area in northeastern Mexico. Some studies have suggested independent evolutionary histories for the multiple populations of blind cavefish Astyanax mexicanus that inhabit this mountain range, despite the hydrological connections that may exist across the Sierra. Barriers between caves could have prevented stygobitic populations to migrate across caves, creating evolutionary significant units localized in discrete biogeographical areas of the Sierra de El Abra. The goal of the present study was to evaluate if there is a correspondence in phylogeographical patterns between Astyanax cavefish and the stygobitic mysid shrimpSpelaeomysis quinterensis. Astyanax mtDNA and mysid histone H3 DNA sequences showed that in both species, cave populations in central El Abra, such as Tinaja cave, are broadly different from other cave populations.
