Abstract Testate amoebae are a frequently used palaeoecological proxy for reconstructing changes in palaeohydrological conditions, particularly studies of Sphagnum -dominated peatlands. Their use has increased following the development transfer functions, allowing quantitative reconstruction water-table depth through time. Increasingly, they included non-pollen palynomorph (NPP) alongside wide ...
Integrated sedimentological, palynological, and palynofacies analyses of the Arrifes section in central Algarve Basin (southern Portugal) provided new information on age environments this Lower Cretaceous sequence. The sedimentary succession at consists fossiliferous interbedded limestones, marly marls, dated as latest Hauterivian to late Barremian (Lower Cretaceous) based key dinoflagellate ta...
This article aims to trace in detail the periods of rapid changes during Late Glacial period based on a subfossil Cladocera analysis and palynological, geochemical, statistical analysis. At end Older Dryas, water level reservoir was low, with quite cold waters inconvenient conditions for developing Cladocera-dominated cold-tolerant species. The beginning Alleröd is marked by increasing vegetati...
New palynological and calcareous nannofossil records are presented for the Turonian–Coniacian boundary section at Salzgitter-Salder, Germany, candidate Coniacian GSSP. The proposed base of Stage is Bed 46, first appearance datum level Cremnoceramus deformis erectus, which coincident with a δ13C minimum top Navigation carbon isotope event. Palynological assemblages dominated by organic walled di...
abstract this study investigated the predictability of variables from a motivational framework as well as individuals qualities to predict three non-linguistic outcomes of language learning. gardners socio-educational model with its measures has been used in the current study. individual qualities presented in this study include (1) age, (2) gender, and (3) language learning experience. the...
The article presents the results of study aeropalinological spectra city Cherepovets (59 ° 07′59 ″ N, 37 53′59 E), carried out during growing season 2014-2015. method gravimetric sampling was used (Durham’s pollen trap). Data obtained on 22 taxa and dynamics dusting various palynomorphs; dominant palinospectrum were identified, as well non-pollen palynomorphs in air. It is shown that Betula gra...
