Warm winters challenge the cultivation of temperate species in South America—a spatial analysis of chill accumulation
(Climatic Change, 2021-12-11)Winter chill accumulation plays a crucial role in determining the moment of bud burst in temperate fruit and nut trees, and insufficient chill can greatly limit yield potentials. To assess future cultivation options for ... -
Youngest Cretaceous dinosaur tracksite from the Middle East (Maastrichtian, Farrokhi Formation, Central Iran)
(Palaeobiodiversity and Palaeoenvironments, 2021-12-07)A late early Maastrichtian dinosaur trampling site is reported from the Farrokhi Formation of the Khur area, Central Iran. The largely indeterminate footprints, some of which may represent undertracks, can be classified ... -
As above, so below? Effects of fungicides on microbial organic matter decomposition are stronger in the hyporheic than in the benthic zone
(Limnology and Oceanography, 2021-11-16)Microbial organic matter decomposition is a critical ecosystem function, which can be negatively affected by chemicals. Although the majority of organic matter is stored in sediments, the impact of chemicals has exclusively ... -
Always ready? Primary production of Arctic phytoplankton at the end of the polar night
(Limnology and Oceanography Letters, 2021-11-11)The end of the polar night with the concurrent onset of photosynthetic biomass production ultimately leads to the spring bloom, which represents the most important event of primary production for the Arctic marine ecosystem. ... -
The Permian–Triassic boundary section at Baghuk Mountain, Central Iran: carbonate microfacies and depositional environment
(Palaeobiodiversity and Palaeoenvironments, 2021-11-03)Sections at Baghuk Mountain, 45 km NNW of Abadeh (Central Iran), have excellent exposures of fossiliferous marine Late Permian to Early Triassic sedimentary successions. Detailed bed-by-bed sampling enables the analysis ... -
Environmental matching reveals non-uniform range-shift patterns in benthic marine Crustacea
(Climatic Change, 2021-10-30)Empirical and theoretical studies suggest that marine species respond to ocean warming by shifting ranges poleward and/or into deeper depths. However, future distributional patterns of deep-sea organisms, which comprise ... -
Highlighting Theodor W. Engelmann's “Farbe und Assimilation” [Color and Assimilation]
(Limnology and Oceanography Bulletin, 2021-10-22)In 1883, Theodor Wilhelm Engelmann, a German scientist, wrote his essay “color and assimilation” (Ger.: “Farbe und Assimilation”) describing the state of the art in photosynthesis research, his recent findings, and further ... -
Neanderthals of Porto Selvaggio in southern Italy: lithic industry of Grotta Torre dell'Alto (Nardò, Lecce)
(Journal of Quaternary Science, 2021-10-18)Porto Selvaggio in southern Italy is where the Uluzzian culture was first identified and documented, providing key insights into the transition from the Middle to the Upper Paleolithic. The area has also yielded evidence ... -
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 ... -
Trees Talk Tremor—Wood Anatomy and δ13C Content Reveal Contrasting Tree‐Growth Responses to Earthquakes
(Journal of Geophysical Research: Biogeosciences, 2021-10-08)Large earthquakes can increase the amount of water feeding stream flows, raise groundwater levels, and thus grant plant roots more access to water in water‐limited environments. We examine growth and photosynthetic responses ... -
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 ... -
Investigating Middle Palaeolithic subsistence: zooarchaeological perspectives on the potential character of hominin climate refugia in Greece
(Journal of Quaternary Science, 2021-09-21)It has long been proposed that during Pleistocene climatic perturbations the Balkan peninsula sustained refugial areas for fauna, flora, and potentially, hominins. In this study, we explore Middle Palaeolithic subsistence ... -
‘Ten Years After’—a long‐term settlement and bioerosion experiment in an Arctic rhodolith bed (Mosselbukta, Svalbard)
(Geobiology, 2021-09-15)Rhodolith beds and bioherms formed by ecosystem engineering crustose coralline algae support the northernmost centres of carbonate production, referred to as polar cold‐water carbonate factories. Yet, little is known about ... -
Life at the continental–marine interface: palaeoenvironments and biota of the Alcobaça Formation (Late Jurassic, Central Portugal), with a formal definition of the unit appended
(Palaeobiodiversity and Palaeoenvironments, 2021-09-13)The Kimmeridgian Alcobaça Formation of the Lusitanian Basin forms a mixed carbonate–siliciclastic unit between basinal deposits of the Abadia Formation, and fluvial–terrestrial strata of the Lourinhã Formation. This study ... -
A partial skeleton of Septencoracias from the early Eocene London Clay reveals derived features of bee-eaters (Meropidae) in a putative stem group roller (Aves, Coracii)
(Palaeobiodiversity and Palaeoenvironments, 2021-09-13)A partial skeleton of the putative stem group roller Septencoracias is described from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK). With an age of about 55 million years, the bones represent one of the ... -
Facies, magnetic susceptibility and timing of the Late Devonian Frasnian/Famennian boundary interval (Xom Nha Formation, Central Vietnam)
(Palaeobiodiversity and Palaeoenvironments, 2021-09-09)Upper Devonian carbonates deposited through the Frasnian/Famennian (F/F) stage boundary in the Xom Nha Formation, Central Vietnam, were studied. The section is mainly composed of fossiliferous, brecciated, and laminated ... -
Understanding crop processing and its social meaning in the Xinzhai period (1850–1750 cal bce): a case study on the Xinzhai site, China
(Vegetation History and Archaeobotany, 2021-09-03)Although the Xinzhai period (1850–1750 cal bce) has been widely regarded as a critical time for the development of urbanization in China, little is known about the labour and social organization of the time. In this paper, ... -
