Recruitment dynamics in conifer-dominated uneven-aged forests in the carpathians

Forest Ecosystems
In permanently uneven-aged forests, continuous ingrowth of recruitment into higher stand layers is a critical process for the formation and maintenance of differentiated stand structures.

Cisovka - the relic population of Abies alba and its relationship to man-made silver-fir stands in Białowieża primeval forest

Acta Societatis Botanicorum Poloniae, 2014
In Białowieża Primeval Forest, in 1823 Stanisław Górski discovered on the Cisovka Hag, a relic population of European silver-fir (Abies alba Mill.). This population is isolated and most away, 120 km to the North-East, from the border of European-silver ...

Chemical Composition and Activity of Essential Oils of Albanian Coniferous Plants on Plant Pests

Chemistry Proceedings, 2022
The present study was conducted to evaluate and compare the chemical composition and bioactivity of essential oils on different insect organisms from four Albanian coniferous plants. The phytochemical analysis carried out using GC-MS showed that the oils

Tree dynamics and co-existence in the montane¿sub-alpine ecotone: the role of different light-induced strategies [PDF]

, 2011
Questions: Is light availability the main factor driving forest dynamics in Pyrenean sub-alpine forests? Do pines and firs differ in growth, mortality and morphological response to low light availability?

Loss of cyclin‐dependent kinase‐like 5 results in susceptibility to audiogenic seizures in mice

Epilepsia Open, EarlyView.
Abstract CDKL5 deficiency disorder (CDD) is a severe neurodevelopmental encephalopathy characterized by early‐onset, treatment‐resistant epilepsy. Mice lacking CDKL5 display several clinically relevant phenotypes, but spontaneous seizures are not consistently reported, and it is unknown if CDD model mice are susceptible to sensory stimulus‐triggered ...

Effects of silver fir (Abies alba Mill.) on the humus forms in Norway spruce (Picea abies (L.) H. Karst.) stands

Journal of Forest Science, 2018
The effects of silver fir (Abies alba Miller) on the soil compared to Norway spruce (Picea abies (Linnaeus) H. Karsten) were evaluated. Altitude of the study site is 790 m a.s.l., mild slope of 10° facing SW, forest site is spruce-beech on acid soil. The

Optimizing Selective RF Pulses for Enhanced Signal Stability in Turbo Spin Echo Using a Differentiable Extended Phase Graph Model

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To improve slice profile consistency across echo trains in turbo spin echo (TSE) imaging, thereby reducing image blurring and increasing the accuracy of multi echo spin echo T2$$ {T}_2 $$ mapping. Methods Excitation and refocusing RF pulses were optimized for TSE using a differentiable extended phase graph model that incorporates the ...
