What is the size-class distribution of A. erioloba mortality? Does the mortality distribution differ from total tree size distribution? Does A. erioloba mortality distribution match the mortality distributions recorded thus far in other environments? Location: Dronfield Ranch, near Kimberley, Kalahari, South Africa. Methods: A combination of aerial photographs and a satellite image covering 61 year was used to provide long-term spatial data on mortality. We used aerial photographs of the study area from 1940, 1964, 1984, 1993 and a satellite image from 2001 to follow three plots covering 510 ha. We were able to identify and individually follow ca. 3000 individual trees from 1940 till 2001. Results: The total number of trees increased over time. No relationship between total number of trees and mean tree size was detected. There were no trends over time in total number of deaths per plot or in size distributions of dead trees. Kolmogorov-Smirnov tests showed no differences in size class distributions for living trees through time. The size distribution of dead trees was significantly different from the size distribution of all trees present on the plots. Overall, the number of dead trees was low in small size classes, reached a peak value when canopy area was 20 - 30 m(2), and declined in lamer size-classes. Mortality as a ratio of dead vs. total trees peaked at intermediate canopy sizes too. Conclusion: A. erioloba mortality was size-dependent, peaking at intermediate sizes. The mortality distribution differs from all other tree mortality distributions recorded thus far. We suggest that a possible mechanism for this unusual mortality distribution is intraspecific competition for water in this semi-arid environment.}, language = {en} } @misc{SchmollSchurrWinkeletal.2006, author = {Schmoll, Tim and Schurr, Frank Martin and Winkel, W. and Lubjuhn, Thomas}, title = {Female extra-pair mating, fitness and genetic diversity: Expression in socially monogamous Coal Tits}, series = {Journal of ornithology}, volume = {147}, journal = {Journal of ornithology}, publisher = {Elsevier}, address = {New York}, issn = {0021-8375}, pages = {248 -- 248}, year = {2006}, language = {en} } @misc{NeyeWallschlaegerTiedemann2006, author = {Neye, Gundula and Wallschl{\"a}ger, Hans-Dieter and Tiedemann, Ralph}, title = {Song dialect boundaries in the Yellowhammer: Do they restrict gene flow?}, series = {Journal of ornithology}, volume = {147}, journal = {Journal of ornithology}, number = {Supplement 1}, publisher = {Blackwell}, address = {New York}, issn = {0021-8375}, pages = {219 -- 219}, year = {2006}, language = {en} } @misc{TiedemannPfautsch2006, author = {Tiedemann, Ralph and Pfautsch, Simone}, title = {MHC evolution in ducks and allies}, series = {Journal of ornithology}, volume = {147}, journal = {Journal of ornithology}, number = {Supplement 1}, publisher = {Blackwell}, address = {New York}, issn = {0021-8375}, pages = {48 -- 48}, year = {2006}, language = {en} } @article{DeneckeKoppitzŠtrakov2006, author = {Denecke, Klaus-Dieter and Koppitz, J{\"o}rg and Štrakov, Slavčo}, title = {Multi-hypersubstitutions and colored solid varieties}, series = {International journal of algebra and computation}, volume = {16}, journal = {International journal of algebra and computation}, number = {4}, publisher = {World Scient.

Terms can be visualized by trees. Hypersubstitutions can be extended to mappings defined on sets of trees. The nodes of the trees, describing terms, are labelled by operation symbols and by colors, i.e. certain positive integers. We are interested in mappings which map differently-colored operation symbols to different terms. In this paper we extend the theory of hypersubstitutions and solid varieties to multi-hypersubstitutions and colored solid varieties. We develop the interconnections between such colored terms and multihypersubstitutions and the equational theory of Universal Algebra. The collection of all varieties of a given type forms a complete lattice which is very complex and difficult to study; multi-hypersubstitutions and colored solid varieties offer a new method to study complete sublattices of this lattice.}, language = {en} } @misc{BousquetDeCapitaniArcay2006, author = {Bousquet, Romain and De Capitani, Christian and Arcay, Diane}, title = {Feedback of the metamorphic changes on the subducting processes}, series = {Geochimica et cosmochimica acta : journal of the Geochemical Society and the Meteoritical Society}, volume = {70}, journal = {Geochimica et cosmochimica acta : journal of the Geochemical Society and the Meteoritical Society}, number = {18}, publisher = {Elsevier}, address = {Oxford}, issn = {0016-7037}, doi = {10.1016/j.gca.2006.06.228}, pages = {A62 -- A62}, year = {2006}, language = {en} } @misc{TenFreyhausHuntgeburthWingleretal.2006, author = {Ten Freyhaus, Henrik and Huntgeburth, Michael and Wingler, Kirstin and Baeumer, A.

They consist of poly(butyl acrylate) as hydrophobic block with a low glass transition temperature and three different nonionic water-soluble blocks, namely, the classical hydrophilic block poly(dimethylacrylamide), the strongly hydrophilic poly(acryloyloxyethyl methylsulfoxide), and the thermally sensitive poly(N-acryloylpyrrolidine). Aqueous micellar solutions of the block copolymers were prepared and characterized by static and dynamic light scattering analysis (DLS and SLS). No critical micelle concentration could be detected. The micellization was thermodynamically favored, although kinetically slow, exhibiting a marked dependence on the preparation conditions. The polymers formed micelles with a hydrodynamic diameter from 20 to 100 nm, which were stable upon dilution. The micellar size was correlated with the composition of the block copolymers and their overall molar mass. The micelles formed with the two most hydrophilic blocks were particularly stable upon temperature cycles, whereas the thermally sensitive poly(N-acryloylpyrrolidine) block showed a temperature-induced precipitation. According to combined SLS and DLS analysis, the micelles exhibited an elongated shape such as rods or worms. It should be noted that the block copolymers with the most hydrophilic poly(sulfoxide) block formed inverse micelles in certain organic solvents.}, language = {en} } @article{AssmannThielRomanoetal.2006, author = {Assmann, Birte and Thiel, Marco and Romano, Maria Carmen and Niemitz, Carsten}, title = {Recurrence plot analyses suggest a novel reference system involved in newborn spontaneous movements}, series = {Behavior research methods : a journal of the Psychonomic Society}, volume = {38}, journal = {Behavior research methods : a journal of the Psychonomic Society}, number = {3}, publisher = {Springer}, address = {New York}, issn = {1554-351X}, doi = {10.3758/BF03192793}, pages = {400 -- 406}, year = {2006}, abstract = {The movements of newborns have been thoroughly studied in terms of reflexes, muscle synergies, leg coordination, and target-directed arm/hand movements.

Here, we report an inquiry in which we explicitly concentrated on taking such a perspective and, additionally, were guided by the methodological concept of home base behavior, which Ilan Golard developed for studies of exploratory behavior in animals. Methods from nonlinear dynamics, such as symbolic dynamics and recurrence plot analyses of kinematic data received from audiovisual newborn recordings, yielded new insights into the spatial and temporal organization of limb movements. In the framework of home base behavior, our approach uncovered a novel reference system of spontaneous newborn movements.}, language = {en} }
