Sequence variation of the internal transcribed spacer (ITS) region of ribosomal DNA in Cerastoderma species (Bivalvia: Cardiidae)

01-02-2010 | Freire, Ruth; Arias, Alberto; Méndez, Josefina; Insua, Ana, Journal of Molluscan Studies, 2010

The internal transcribed spacer (ITS) region of ribosomal DNA (ITS1, 5.8S rRNA gene and ITS2) constitutes one of the most widely applied molecular markers in phylogenetic studies and species differentiation. Here, the ITS region of the cockles Cerastoderma edule from NW Spain and C. glaucum ...

Diversity and body-size patterns of land snails in rain forests in Uganda

01-02-2010 | Wronski, Torsten; Hausdorf, Bernhard, Journal of Molluscan Studies, 2010

We investigated land-snail faunas of rain forests along the Albertine Rift Valley and the Lake Victoria forest belt in Uganda. Sixty plots in 13 forests were studied, covering low altitude to montane forest types ranging in altitude from 680 to 2,770 m. Approximately 16,000 specimens were ...

Snail faunas in the Southern Ural forests and their relations to vegetation: an analogue of the Early Holocene assemblages of Central Europe?

01-02-2010 | Horsák, Michal; Chytrý, Milan; Danihelka, Jiří; Kočí, Martin; Kubešová, Svatava; Lososová, Zdeňka; Otýpková, Zdenka; ..., Journal of Molluscan Studies, 2010

A malacological study at 41 forest sites in the Southern Urals (Bashkortostan, Russia) conducted in 2007 gave the first quantitative data about land snail assemblages from this region. These data were used to identify the main patterns and predictors of snail species richness and ...

Environmental influences in the evolution of tetrapod hearing sensitivity and middle ear tuning

01-12-2009 | Gridi-Papp, Marcos; Narins, Peter M., Integrative and Comparative Biology, 2009

Vertebrates inhabit and communicate acoustically in most natural environments. We review the influence of environmental factors on the hearing sensitivity of terrestrial vertebrates, and on the anatomy and mechanics of the middle ears. Evidence suggests that both biotic and abiotic ...

The influence of viscous hydrodynamics on the fish lateral-line system

01-12-2009 | Windsor, Shane P.; McHenry, Matthew J., Integrative and Comparative Biology, 2009

Fish exhibit many behaviors that involve sensing water flows with their lateral-line system. In many situations, viscosity affects how the flow interacts with the body of the fish and the neuromasts of the lateral line. Here we discuss how viscosity influences the stimulus to the fish ...

Active touch, exploratory movements, and sensory prediction

01-12-2009 | Hartmann, Mitra J. Z., Integrative and Comparative Biology, 2009

The relation between somatosensory input and motor output is asymmetric. Somatosensation is associated with every movement an animal makes, but movement is not required for somatosensation. This symposium paper proposes a classification scheme for movement, in which movements are placed ...

Using Drosophila for studying fundamental processes in hearing

01-12-2009 | Lu, Qianhao; Senthilan, Pingkalai R.; Effertz, Thomas; Nadrowski, Björn; Göpfert, Martin C., Integrative and Comparative Biology, 2009

Apart from detecting sounds, vertebrate ears occasionally produce sounds. These spontaneous otoacoustic emissions are the most compelling evidence for the existence of the cochlear amplifier, an active force-generating process within the cochlea that resides in the motility of the hair ...

Maternal care and altered social phenotype in a recently collected stock of Astatotilapia burtoni cichlid fish

01-12-2009 | Renn, Suzy C. P.; Carleton, Julia B.; Magee, H.; Nguyen, My Linh T.; Tanner, Ameara C. W., Integrative and Comparative Biology, 2009

For over 30 years, the African cichlid fish, Astatotilapia burtoni, has been an important model system for studying the mechanisms underlying socially mediated behavioral change, with the focus being the dominance behavior of males. A recently collected wild-stock (WS) of this species ...

Interspecific profiling of gene expression informed by comparative genomic hybridization: A review and a novel approach in African cichlid fishes

01-12-2009 | Machado, Heather E.; Pollen, Alexander A.; Hofmann, Hans A.; Renn, Suzy C.P., Integrative and Comparative Biology, 2009

Modern genomic approaches have facilitated great progress in our understanding of the molecular and genetic underpinnings of ecological and evolutionary processes. Analysis of gene expression through heterologous hybridization in particular has enabled genome-scale studies in many ...

Gene duplication and differential gene expression play an important role in the diversification of visual pigments in fish

01-12-2009 | Hofmann, Christopher M.; Carleton, Karen L., Integrative and Comparative Biology, 2009

Sensory systems provide crucial information about an organism's external environment and, thus, are often subject to strong natural selection. Because of the large variation in the intensity and spectral quality of light in aquatic environments, studies of sensory adaptation have focused on ...
