Population genetics of the brooding coral Seriatopora hystrix reveals patterns of strong genetic differentiation in the Western Indian Ocean Vrije Universiteit Brussel

Rosa Van Der Ven, Jean-François Flot, Carol Nathaly Buitrago López, Marc Kochzius

Coral reefs provide essential goods and services but are degrading at an alarming rate due to local and global anthropogenic stressors. The main limitation that prevents the implementation of adequate conservation measures is that connectivity and genetic structure of populations are poorly known. Here, the genetic diversity and connectivity of the brooding scleractinian coral Seriatopora hystrix were assessed at two scales by genotyping ten ...

Population Genetic Analysis of the Estonian Native Horse Suggests Diverse and Distinct Genetics, Ancient Origin and Contribution from Unique Patrilines KU Leuven

Gabriella Lindgren
The Estonian Native Horse (ENH) is a medium-size pony found mainly in the western islands of Estonia and is well-adapted to the harsh northern climate and poor pastures. The ancestry of the ENH is debated, including alleged claims about direct descendance from the extinct Tarpan. Here we conducted a detailed analysis of the genetic makeup and relationships of the ENH based on the genotypes of 15 autosomal short tandem repeats (STRs), 18 Y ...

Characterization of fine geographic scale population genetics in sugar kelp (Saccharina latissima) using genome-wide markers Ghent University

Signe Bråtelund, Tom Ruttink, Franz Goecke, Ole Jacob Broch, Gunnar Klemetsdal, Jørgen Ødegård, Åshild Ergon
Background: Kelps are not only ecologically important, being primary producers and habitat forming species, they also hold substantial economic potential. Expansion of the kelp cultivation industry raises the interest for genetic improvement of kelp for cultivation, as well as concerns about genetic introgression from cultivated to wild populations. Thus, increased understanding of population genetics in natural kelp populations is crucial. ...

Population genetics of African Schistosoma species Institute of Tropical Medicine KU Leuven

O. Rey, Bonnie L. Webster, Tine Huyse, D Rollinson, Frederik Van den Broeck, J. Kincaid-Smith, A. Onyekwere, J. Boissier

Blood flukes within the genus Schistosoma (schistosomes) are responsible for the major disease, schistosomiasis, in tropical and sub-tropical areas. This disease is predominantly present on the African continent with more than 85% of the human cases. Schistosomes are also parasites of veterinary importance infecting livestock and wildlife. Schistosoma population genetic structure and diversity are important characteristics that may reflect ...

Population genetics of the East African White-eye species complex Ghent University

Jan Christian Habel, Siobhan Cox, Franz Gassert, Ronald K Mulwa, Jobst Meyer, Luc Lens
The Eastern Afromontane biodiversity hotspot consists of isolated mountain massifs embedded within the dry lowland savannas of East Africa and of which the peaks and ridges are covered by cloud forest remnants. These cloud forests are home to the Mountain White-eye (Zosterops poliogaster), while three congeneric species (Abyssinian White-eye, Zosterops abyssinicus; Yellow White-eye, Zosterops senegalensis; Pemba White-eye, Zosterops vaughani) ...

Population and landscape genetics in the water flea Daphnia KU Leuven

Summary The population genetic structure of natural populations in landscapes is the result of a complex interaction between ecological and evolutionary processes such as gene flow, genetic drift and selection, which in turn are shaped by landscape characteristics (environmental gradients and geography), historical processes, or their combined effects. Understanding the relative role of these processes is fundamental to improve our ecological ...

Sex ratio variation and population genetics of gynodioecious plant species KU Leuven

Sascha van der Meer
Plants display remarkable sexual diversity. Regardless of this variation, most flowering plants are hermaphrodites and contain flowers with both male and female sex organs. However, various sexual systems have evolved in which male and female organs have been separated between flowers and between individuals. In gynodioecious species, hermaphrodites co-exist with females, plants that lack pollen production (male-sterile individuals). Since ...

Contribution of genetics for implementing population translocation of the threatened Arnica montana. Meise Botanic Garden

Fabienne Van Rossum, Olivier Raspé
Ecological restoration programmes aiming at population recovery of imperilled plant species increasingly involve plant translocations. Evaluating the genetic status of seed source and target populations is essential for designing plant translocation protocols and optimizing recovery success. We developed nine polymorphic microsatellite markers and used three plastid markers to investigate genetic variation and structure of the two last large and ...

The impact of urbanization on population genetics and microorganisms associated with floral nectar of Linaria vulgaris ,, KU Leuven

Jacek Bartlewicz
Entering the XXIst century, humanity will face enormous challenges to its continued prosperity. This is because the ecosystem in which mankind participates is undergoing planetary scale alterations, giving birth to new unprecedented problems. The growth and changing distribution of human population is a constituent part of this so-called global change, and must be carefully studied in order to give the coming generations a chance for a better ...
