A little bit of sex matters for genome evolution in asexual plants.
Genome evolution in asexual organisms is theoretically expected to be shaped by various factors: first, hybrid origin, and polyploidy confer a genomic constitution of highly heterozygous genotypes with multiple copies of ...
Harnessing the biodiversity value of Central and Eastern European farmland
A large proportion of European biodiversity today depends on habitat provided by low-intensity farming practices, yet this resource is declining as European agriculture intensifies. Within the European Union, particularly ...
Beiträge zum Göttinger Umwelthistorischen Kolloquium 2004 - 2006.
(Universitätsverlag Göttingen, 2007)
Seit seiner Gründung vor annähernd 25 Jahren hat sich das Göttinger Umwelthistorische Kolloquium zu einer Einrichtung entwickelt, welche die vielfältigen, thematisch einschlägigen Aktivitäten des Standortes wie auch des ...
Does the Stimulus Type Influence Horses’ Performance in a Quantity Discrimination Task?
The ability to understand the relation between quantities has been documented in a wide range of species. Such quantity discrimination competences are commonly demonstrated by a choice of the larger quantity or numerosity ...
I Dare You to Punish Me—Vendettas in Games of Cooperation
Everybody has heard of neighbours, who have been fighting over some minor topic for years. The fight goes back and forth, giving the neighbours a hard time. These kind of reciprocal punishments are known as vendettas and ...
The statistical theories of Fisher and of Neyman and Pearson: A methodological perspective
(SAGE Publications, 2013)
Most of the debates around statistical testing suffer from a failure to identify clearly the features specific to the theories invented by Fisher and by Neyman and Pearson. These features are outlined. The hybrids of ...
Molecular biology and riddle of cancer: the ‘Tom & Jerry’ show
(Springer Milan, 2011)
From the conventional Bird’s eye, cancer initiation and metastasis are generally intended to be understood beneath the light of classical clonal genetic, epigenetic and cancer stem cell model. But inspite decades of ...
The Allometry of Prey Preferences
The distribution of weak and strong non-linear feeding interactions (i.e., functional responses) across the links of complex food webs is critically important for their stability. While empirical advances have unravelled ...
Molecular Evidence for the Wide Distribution of Two Lineages of Terrestrial Green Algae (Chlorophyta) over Tropics to Temperate Zone
Phylogenetic analyses of 18S rDNA sequences from environmental clones and culture strains revealed a widespread distribution of two subaerial green algal lineages, Jenufa and Xylochloris, recently described from rainforests ...
BMP signals and the transcriptional repressor BLIMP1 during germline segregation in the mammalian embryo
Molecular factors and tissue compartments involved in the foundation of the mammalian germline have been mainly described in the mouse so far. To find mechanisms applicable to mammals in general, we analyzed temporal and ...
