Contrasting Global Patterns of Spatially Periodic Fairy Circles and Regular Insect Nests in Drylands
(Journal of Geophysical Research: Biogeosciences, 2019)Numerical analysis of spatial pattern is widely used in ecology to describe the characteristics of floral and faunal distributions. These methods allow attribution of pattern to causal mechanisms by uncovering the specific ... -

Coralline demosponges ; a geobiological portrait
(Bulletin / The Tohoku University Museum, 2001)The polyphyletic coralline demosponges possess a calcareous basal skeleton of 4 major morphotypes. Each has its own phylogenetic history, with different mechanisms of formation. One extant taxon of each skeletal type has ... -

Countergradient variation concealed adaptive responses to temperature increase in Daphnia from heated lakes
(Limnology and Oceanography, 2020-12-21)To test the general assumption that global warming will induce body size reduction in aquatic organisms, we used a system of lakes continually heated for six decades by warm water discharge from power plants. Their temperature ... -
Coupled changes in traits and biomasses cascading through a tritrophic plankton food web
(Limnology and Oceanography, 2020)Trait-based approaches have broadened our understanding of how the composition of ecological communities responds to environmental drivers. This research has mainly focussed on abiotic factors and competition determining ... -
Cryptogamic organisms are a substantial source and sink for volatile organic compounds in the Amazon region
(Communications Earth & Environment, 2021-12-21)Cryptogamic organisms such as bryophytes and lichens cover most surfaces within tropical forests, yet their impact on the emission of biogenic volatile organic compounds is unknown. These compounds can strongly influence ... -
Current extinction rate in European freshwater gastropods greatly exceeds that of the late Cretaceous mass extinction
(Communications Earth & Environment, 2021-05-21)The Cretaceous–Paleogene mass extinction event 66 million years ago eradicated three quarters of marine and terrestrial species globally. However, previous studies based on vertebrates suggest that freshwater biota were ... -
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 ... -
Description of the first Rhaetian nautiloid (Grypoceras rhaeticum n. sp.) from the Kössen Beds of the Fonsjoch near Achensee (Austria)

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 ... -
Die "Weichteilbelemniten" des Posidonienschiefers (Untertoarcium) von Holzmaden (Baden-Württemberg) sind Fälschungen
(Neues Jahrbuch für Geologie und Paläontologie,, 1979)The "soft-part-belemnites" In the Holzmaden Posidonia Shales are forged. · Soft-parts of Phragmoteuthis conocauda (QUENSTEDT) have been compounded with belemnite rostra of Passaloteuthis paxillosa (SCHLOTHEIM). The ...
