Inbreeding Effects in Eucalyptus grandis in Relation to Degree of Relatedness
Item type: Journal Article • Journal: South African Forestry Journal • Authors: G. van Wyk --- Department of Water Affairs, Forestry and Environmental Conservation,Introductory remarks refer to the detrimental effects of selfing in E. grandis. How do other types of inbreeding such as the mating of half-sibs or full-sibs compare with out-crossed material? Results from two trials are presented comparing growth performance of... -
Low genetic diversity and high genetic differentiation among severely fragmented populations of the critically endangered tree Talbotiella gentii (Fabaceae)
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: D Dompreh --- School of Biological Sciences, UK MD Swaine --- School of Biological Sciences, UK A Price --- School of Biological Sciences, UKThe genetic diversity among 17 populations (including 10 newly discovered) of Talbotiella gentii (Fabaceae, Caesalpinioideae), a rare tree species endemic to Ghana, was assessed using random amplified polymorphic DNA (RAPD). A total of 80 polymorphic bands were generated from eight... -
Advances in reproductive biology and seed production systems of Eucalyptus: the case of Eucalyptus globulus
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: BM Potts MH McGowen DR Williams S Suitor TH Jones PL Gore RE VaillancourtEucalyptus globulus is the main eucalypt species grown in Australian plantations. The focus on seedling deployment systems, coupled with exploitation of large, open-pollinated base populations for breeding purposes over the last two decades, has required a detailed understanding of the... -
Reproductive biology of the critically endangered tropical tree Talbotiella gentii
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Daniel Dompreh --- Department of Plant and Soil Science, UK Michael D Swaine --- Department of Plant and Soil Science, UK Christopher C Wilcock --- Department of Plant and Soil Science, UKTalbotiella gentii is a critically endangered caesalpiniaceous legume endemic to Ghana, restricted in distribution to the margins of the forest zone where there has been extensive fire damage in recent decades. It occurs as isolated, near-monospecific populations, some of which... -
Characterisation of microsatellite markers in the Spotted Sand Lizard (Pedioplanis lineoocellata) shows low levels of inbreeding and moderate genetic diversity on a small spatial scale
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Krystal A. Tolley --- , , South Africa Ryan J. Daniels --- , , South Africa Kevin A. Feldheim --- , , USAPopulation genetic methods can be useful for understanding spatial genetic patterns, gene flow and diversity. While genetic markers such as gene sequences are useful for understanding broad scale phylogeographic patterns, microsatellite markers allow for inferences within species and on smaller...
