Genomic Insights into Adaptation to Karst Limestone and Incipient Speciation in East Asian Platycarya spp. (Juglandaceae). Vlaams Instituut voor Biotechnologie
Hybrid speciation leads to novel male secondary sexual ornamentation of an Amazonian bird Universiteit Gent
Cryptic diversity and speciation in endemic Cytherissa (Ostracoda, Crustacea) from Lake Baikal Universiteit Hasselt Universiteit Gent
Lake Baikal (Siberia) is the most ancient and deepest of all ancient lakes on Earth. It holds a (mostly endemic) diversity of thousands of animal species, including a speciose radiation of ostracods of the genus Cytherissa. Applying molecular tools to this crustacean group reveals that several morphological species are actually species clusters. Based on combined 16S and 28S DNA sequence data from thirteen classic Cytherissa species and one ...
Integrative response of arsenic uptake, speciation and detoxification by Salix atrocinerea Universiteit Hasselt
Despite arsenic (As) being very toxic with deleterious effects on metabolism, it can be tolerated and accumulatedby some plants. General genetic mechanisms responsible for As tolerance in plants, includingSalixspecies, havebeen described in transcriptomic analysis, but further experimental verification of the significance of particulartranscripts is needed. In this study, aSalix atrocinereaclone, able to thrive in an As-contaminated ...
The Role of Plasticity and Adaptation in the Incipient Speciation of a Fire Salamander Population KU Leuven
Phenotypic plasticity and local adaptation via genetic change are two major mechanisms of response to dynamic environmental conditions. These mechanisms are not mutually exclusive, since genetic change can establish similar phenotypes to plasticity. This connection between both mechanisms raises the question of how much of the variation observed between species or populations is plastic and how much of it is genetic. In this study, we used a ...
Complete mitochondrial genomes and updated divergence time of the two freshwater clupeids endemic to Lake Tanganyika (Africa) suggest intralacustrine speciation KU Leuven Universiteit Antwerpen Universiteit Hasselt
BACKGROUND: The hydrogeological history of Lake Tanganyika paints a complex image of several colonization and adaptive radiation events. The initial basin was formed around 9-12 million years ago (MYA) from the predecessor of the Malagarasi-Congo River and only 5-6 MYA, its sub-basins fused to produce the clear, deep waters of today. Next to the well-known radiations of cichlid fishes, the lake also harbours a modest clade of only two clupeid ...
Ancient Tethyan vicariance and long-distance dispersal drive global diversification and cryptic speciation in the red seaweed Pterocladiella Universiteit Gent Plantentuin Meise / Agentschap Plantentuin Meise
We investigated the globally distributed red algal genus Pterocladiella, comprising 24 described species, many of which are economically important sources of agar and agarose. We used DNA-based species delimitation approaches, phylogenetic, and historical biogeographical analyses to uncover cryptic diversity and infer the drivers of biogeographic patterns. We delimited 43 species in Pterocladiella, of which 19 are undescribed. Our multigene ...
Variation in parasite infection between replicates of speciation in Lake Victoria cichlid fish Universiteit Hasselt KU Leuven
Because of potentially strong eco-evolutionary interactions with their hosts, parasites may initiate or enhance host diversification. The adaptive radiation of cichlid fish in Lake Victoria provides a good system to study the role of parasites at different stages of host speciation. We analyzed the macroparasite infection of four replicates of sympatric blue and red Pundamilia species pairs that vary in their age and extent of differentiation. ...
Mitochondrial DNA variation and cryptic speciation within the free-living marine nematode Pellioditis marina Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
An inverse correlation between dispersal ability and genetic differentiation among populations of a species is frequently observed in the marine environment. We investigated the population genetic structure of the free-living marine nematode Pellioditis marina. A total of 426 bp of the mitochondrial cytochrome oxidase subunit 1 (COI) gene were surveyed on a geographical scale of approximately 100 km during spring 2003. Nematodes were collected ...
