SCHMIDT-RHAESA, A.; ROTHE, B.H.; University Bielefeld, Germany; University Bielefeld, Germany: Postembryonic development of the musculature in kinorhynchs Labelling of f-actin with phalloidin and investigation using confocal laser scanning microscopy is an ideal tool to reveal the architecture of the muscle system in wholemounts of microscopically small animals. The invesitgation of postembryonic stages of the kinorhynch […]

Neurogenesis in myriapods and chelicerates and its importance for understanding arthropod relationships
STOLLEWERK, A; University of Cambridge: Neurogenesis in myriapods and chelicerates and its importance for understanding arthropod relationships The arthropods form a diverse group consisting of insects, crustaceans, chelicerates and myriapods. They show a high variation of neural structures adapted to the specialized behaviour and lifestyles of the individual species. This raises the question of how […]
Concordance of molecular and morphological data The example of Acoela
HOOGE, M.D.*; TYLER, S; The University of Maine, Orono; The University of Maine, Orono: Concordance of molecular and morphological data: The example of Acoela Morphological features of the Acoela appear to be quite plastic, including those of the copulatory organs, which provide the principle characters used for the systematics of this group. Consequently, classification schemes […]
Challenging received wisdom integrating the new microscopy with the new animal phylogeny
JENNER, RA; University of Cambridge: Challenging received wisdom: integrating the new microscopy with the new animal phylogeny Many of the ideas about the broad pattern of animal evolution that have been accepted as textbook knowledge for a long time are currently being fundamentally revised. Although molecular phylogenetics has been the main impetus for these revisions, […]
A Novel Methology Utilizing Confocal Laser Scanning Microscopy for Systematic Analysis in Arthropods
KLAUS, Angela V.; SCHAWAROCH, Valerie; American Museum of Natural History; Baruch College: A Novel Methology Utilizing Confocal Laser Scanning Microscopy for Systematic Analysis in Arthropods The use of confocal laser scanning microscopy (CLSM) for imaging arthropod structures has the potential to profoundly impact systematics of this group. Three-dimensional (3D) reconstruction of CLSM data provides high-fidelity, […]
What good is grouping for geckos Testing the benefits of aggregation in Coleonyx variegatus
LANCASTER, J.R.*; ESPINOZA, R.E.; California State Univ., Northridge: What good is grouping for geckos? Testing the benefits of aggregation in Coleonyx variegatus Social aggregations have been studied in a variety of animals and found to have important social, ecological, and fitness implications. Several species of nocturnal geckos form diurnal aggregations; however, few studies have attempted […]
Validation of Temperature-Based Methods for Estimating Hatchling Sex Ratios in the Kemp&8217;s Ridley Sea Turtle

Ultrastructural development and differentiation of the mantle musculature in embryonic squid
MARTINEZ, G.M.; University of New Hampshire: Ultrastructural development and differentiation of the mantle musculature in embryonic squid The muscular mantle of squids has two primary functions:locomotion and respiration. The capacity of the mantle to execute these dual functions is due to the presence of two distinct muscle fiber types that are functionally and metabolically analogous […]
Trade-offs of inducible defenses in blue mussels (Mytilus edulis) in response to multiple predators with differing attack strategies
FREEMAN, A. S.; University of New Hampshire: Trade-offs of inducible defenses in blue mussels (Mytilus edulis) in response to multiple predators with differing attack strategies. Examples of induced defenses in response to simultaneous cues from multiple predators are rare, despite being a more realistic representation of multiple predator environments. I compared the inducible defensive responses […]
Tracheal compression patterns involved in gas exchange in the ground beetle, Platynus decentis
SOCHA, J.J.*; FEZZAA, K.; LEE, W.K.; WATERS, J.S.; WESTNEAT, M.W.; Argonne National Laboratory; Argonne National Laboratory; Argonne National Laboratory; University of Chicago; University of Chicago: Tracheal compression patterns involved in gas exchange in the ground beetle, Platynus decentis Insects use a variety of mechanisms to actively exchange respiratory gases. Tracheal compression is a recently described […]
