We present data on the temporal distribution of planktonic foraminifer genotypes (small
subunit (SSU) ribosomal (r) RNA gene) and morphospecies (sediment traps) collected …

The toxin-producing microbial species Alexandrium minutum has a wide distribution in the
Mediterranean Sea and causes high biomass blooms with consequences on the …

Planktonic foraminifera are heterotrophic sexually reproducing marine protists with an
exceptionally complete fossil record that provides unique insights into long-term patterns …

Numerous planktonic species have disjunct distribution patterns in the world's oceans.
However, it is unclear whether these are truly unconnected by gene flow, or whether they …

The evolution of large marine mammals and their invasion of the pelagic realm is tied to the
availability of sufficient food, which in turn is linked to upwelling areas and other highly …

Organisms with sexual and asexual reproductive systems benefit from both types of
reproduction. Sexual recombination generates new combinations of alleles, whereas …

Molecular studies of marine plankton have shown that ecological and/or environmental
barriers play an important role in separating populations. Calanoid copepods are central in …

Although the oceans cover 70% of the Earth's surface and the open ocean is by far the
largest ecosystem on the planet, our knowledge regarding diversity patterns of pelagic fauna …

Advances in molecular biology and genetics are revealing that many recognized
crocodylian species are complexes of two or more cryptic species. These discoveries will …

Over the last century, a large body of literature emerged on mechanisms driving speciation.
Most of the research into these questions focussed on terrestrial systems, while research in …
