Abstract Snow petrels (
Pagodroma nivea ), which are endemic to the Antarctic ... -
Remarkably high and consistent tolerance of a Red Sea coral to acute and chronic thermal stress exposures
; Fine, Maoz; Perna, Gabriela; ; Barshis, Daniel J. (Limnology and Oceanography, 2021-02-15)
Global warming is resulting in unprecedented levels of coral mortality due to mass bleaching events and, more recently, marine heatwaves, where rapid increases in seawater temperature cause mortality within days. Here, we ... -

Response of large benthic foraminifera to climate and local changes: Implications for future carbonate production
; Reymond, Claire E.; ; Doo, Steve; Schmidt, Christiane; ; Westphal, Hildegard (Sedimentology, 2021-05-18)
Large benthic foraminifera are major carbonate components in tropical carbonate platforms, important carbonate producers, stratigraphic tools and powerful bioindicators (proxies) of environmental change. The application ... -
Reversals in Temperature‐Precipitation Correlations in the Northern Hemisphere Extratropics During the Holocene
; ; ; ; ; ; ; (Geophysical Research Letters, 2022-11-11)
Future precipitation levels remain uncertain because climate models have struggled to reproduce observed variations in temperature‐precipitation correlations. Our analyses of Holocene proxy‐based temperature‐precipitation ... -
Review of Devonian-Carboniferous Boundary sections in the Rhenish Slate Mountains (Germany)
; ; (Palaeobiodiversity and Palaeoenvironments, 2021-03-25)
Thirty Devonian-Carboniferous Boundary sections of the Rhenish Slate Mountains and adjacent subsurface areas are reviewed with respect to litho-, event, conodont, ammonoid, sequence, and chemostratigraphy. In the interval ... -
Revisiting global trends in freshwater insect biodiversity: A reply
; ; ; (Wiley Interdisciplinary Reviews: Water, 2020-12-31)
Jähnig et al. make some useful points regarding the conclusions that can be drawn from our meta‐analysis; however, some issues require clarification. First, we never suggested that there was a globally increasing trend of ... -
Revisiting Global Vegetation Controls Using Multi‐Layer Soil Moisture
; ; ; ; ; (Geophysical Research Letters, 2021-06-07)
The productivity of terrestrial vegetation is determined by multiple land surface and atmospheric drivers. Water availability is critical for vegetation productivity, but the role of vertical variability of soil moisture ... -
Rhizobien in der Pflanzenmikrobiota
(Biologie in unserer Zeit, 2019)Für das Wachstum und Überleben der Pflanze im Boden ist ihre Mikrobiota von maßgeblicher Bedeutung. Pflanzen-Mikrobiota-Interaktionen können unter Laborbedingungen durch definierte Gemeinschaften von Kommensalen nachgestellt ... -
Role of trait combinations, habitat matrix, and network topology in metapopulation recovery from regional extinction
; ; (Limnology and Oceanography, 2019)
We studied the role of oceanographic conditions and life history strategies on recovery after extinction in a metapopulation of marine organisms dispersing as pelagic larvae. We combined an age-structured model with scenarios ... -
Salinity effects on cultured Neogloboquadrina pachyderma (sinistral) from high latitudes: new paleoenvironmental insights
; ; ; ; (Geo-Marine Letters, 2021-01-05)
This study presents culture experiments of the cold water species Neogloboquadrina pachyderma (sinistral) and provides new insights into the incorporation of elements in foraminiferal calcite of common and newly established ... -

Sea shell diversity and rapidly evolving secretomes: insights into the evolution of biomineralization.
(Frontiers in zoology, 2016)An external skeleton is an essential part of the body plan of many animals and is thought to be one of the key factors that enabled the great expansion in animal diversity and disparity during the Cambrian explosion. ... -
Seasonal dynamics and characterization of coccolithophore export production in two major upwelling regions - Cape Blanc (NW-Africa) & Chile (30 °S)
(Univ. Bremen, 2008)Coccolithophores, a major group of the nanophytoplankton, belong to the class Prymnesiophyceae.The cells of coccolithophores are typically surrounded by layer(s) of calcium carbonate plates, the coccoliths. Certain ... -
Sedimentary DNA identifies modern and past macrophyte diversity and its environmental drivers in high‐latitude and high‐elevation lakes in Siberia and China
; ; ; ; ; ; ; (Limnology and Oceanography, 2022-03-16)
Arctic and alpine aquatic ecosystems are changing rapidly under recent global warming, threatening water resources by diminishing trophic status and changing biotic composition. Macrophytes play a key role in the ecology ... -
Silica entry and accumulation in standing trees in a hot-spring environment: cellular pathways, rapid pace and fossilization potential
; Gee, Carole T. (Palaeontology, 2020)
Silicification is the most important process of fossilization resulting in the preservation of internal tissues in plants, thereby providing essential information on the anatomy, life history, and evolution of land plants. ... -
Simultaneous recording of filtration and respiration in marine organisms in response to short‐term environmental variability
; ; ; ; ; (Limnology and Oceanography: Methods, 2021-01-18)
Climate change imposes unusual long‐term trends in environmental conditions, plus some tremendous shifts in short‐term environmental variability, exerting additional stress on marine ecosystems. This paper describes an ...
