Chromosome inheritance in hybrids between Viviparus snail species and postcopulatory sexual selection in the yellow dung fly


Sbilordo, S. Chromosome inheritance in hybrids between Viviparus snail species and postcopulatory sexual selection in the yellow dung fly. 2010, University of Zurich, Faculty of Science.

Abstract

This dissertation comprises the results of five microscopical studies addressing issues related to sexual reproduction. The main focus of the first two studies (Chapters 1-2) on water snail hybrids lies on chromosomal differences and their potential involvement in isolation mechanisms between these hybridizing species. The two studies on the yellow dung fly Scathophaga stercoraria were aimed at investigating either anatomical structures (Chapter 3) or physiological processes (Chapter 4) involved in sperm transport and utilization with special reference to the potential of female control of these processes. The Chapter 5 consists of supporting material on the karyotype of Scathophaga stercoraria.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
