Deep genetic divergences among Indo-Pacific populations of the coral reef sponge Leucetta chagosensis (Leucettidae): Founder effects, vicariance, or both? - Research article
(BMC evolutionary biology, 2008)Background: An increasing number of studies demonstrate that genetic differentiation and speciation in the sea occur over much smaller spatial scales than previously appreciated given the wide distribution range of many ... -

Depth-distribution of lake benthic diatom assemblages in relation to light availability and substrate: implications for paleolimnological studies
(Journal of Paleolimnology, 2020-06-25)We analyzed the depth distributions of benthic diatoms in two adjacent, but hydrologically distinct subalpine lakes (Lakes Soiernseen, S-Germany). Lake Unterer Soiernsee is affected by marked water-level fluctuations and ... -

Desert breath—How fog promotes a novel type of soil biocenosis, forming the coastal Atacama Desert’s living skin
(Geobiology, 2019)The Atacama Desert is the driest non-polar desert on Earth, presenting precarious conditions for biological activity. In the arid coastal belt, life is restricted to areas with fog events that cause almost daily wet–dry ... -
Devonian-Carboniferous boundary sections in Iran
(Palaeobiodiversity and Palaeoenvironments, 2020-09-30)Many sections are known from Iran which exhibit sediments across the Devonian-Carboniferous (D-C) boundary. In contrast to the majority of published D-C sections worldwide from pelagic/hemipelagic environments, successions ... -

Dinosaurian survivorship schedules revisited: new insights from an age‐structured population model
(Palaeontology, 2021-10-13)Little is known of dinosaur population biology due to insufficient information on age‐dependent fecundities and mortalities. So far, survivorship curves (SC) of only six dinosaurs (four tyrannosaurs, one ceratopsian, one ... -
Dispersal, location of bloom initiation, and nutrient conditions determine the dominance of the harmful dinoflagellate Alexandrium catenella: A meta‐ecosystem study
(Limnology and Oceanography, 2021-09-27)Harmful algal blooms (HABs) are globally increasing in number and spatial extent. However, their propagation dynamics along environmental gradients and the associated interplay of abiotic factors and biotic interactions ...
