Calcareous nannofossil assemblages recovered from a long, continuous section have been described from the Sarayan region in Lut Block in east Iran. The marine Upper Cretaceous sediments of this section yield medium diverse and well-preserved calcareous nannofossil assemblages. A structural analysis of Upper Cretaceous calcareous nannofloras has revealed 30 nannofossil species. A revised zonatio...

Myxomycetes called Plasmodial slime moulds, or true molds are eukaryotic microorganisms. They live in a variety of ecosystems. Genus Didymium Schrad. (family Didymiaceae) is myxomycete taxon containing calcareous peridia (order Physarida) and non-calcareous capillitium. listeri Massee were recorded this study for the first time from Turkey. D. sporocarp was found laboratory by moist chamber cul...

in a greenhouse experiment, changes in inorganic phosphorus fractions as well as their availability in the rhizosphere of rice (oryza sativa c.v. khazar) crop, following an application of 40 mg p (as monocalcium phosphate per kg of soil) were investigated in paddy soils north of iran. the study was performed as a 14×2 factorial in a completely randomized design of two factors namely: soil at 14...

A calcareous nannofossils biostratigraphic study has been carried out on the chalky limestones located in South Gorgan, north of Iran. The study is aimed at determining the age and nannofossil biozonations of the well. The samples were prepared using smear slide technique. Thirty seven calcareous nannofossils species were identified and used to make biostratigraphic zonations and dating of the ...

Changes in the carbon stocks of stem biomass, organic layers and the upper 50 cm of the mineral soil during succession and afforestation of spruce (Picea abies) on former grassland were examined along six chronosequences in Thuringia and the Alps. Three chronosequences were established on calcareous and three on acidic bedrocks. Stand elevation and mean annual precipitation of the chronosequenc...

ABSTRACT Perched marshes in Lunenburg County differ exposure to prevailing waves (from most least exposed: Crescent Beach, Blue Rocks, Feltzen South). We sampled the middle marsh, recording replicates’ dried masses. In picking stage 1 (PS1), first 400 foraminifera, whether agglutinated or calcareous-walled, were picked and identified. From these data we calculated Shannon Function H compared be...

Background and aims – The research aim was to investigate the relation between large-scale geographic factors functional structure of herbaceous layer calcareous beech forests in Apennines, managed as high forest. Material methods We selected 163 plots (20 × 20 m), ranging from Central South Italy, using a random stratified sampling design. correlated effect sizes traits&amp...

Benthic foraminifera (BF) are utilized in palaeo-environmental reconstruction based on our understanding of how living individuals respond to environmental variations. However, there is still a lack empirical insight into non-environmental factors, such as taphonomic processes, influence the preservations fossil BF strata. In this study, we compare spatial distribution and composition alive dea...
