Intra-Annual Course of Canopy Parameters and Phenological Patterns for a Mixed and Diverse Deciduous Forest Ecosystem Along the Altitudinal Gradients Within a Dam Reservoir Landscape

open access: yesDiversity
Within a dam reservoir landscape in the Western Black Sea Region of Türkiye, a dense young-mature stand composed diversely of oriental beeches, European hornbeams, sessile oaks, and silver lindens was chosen as a study field to analyze canopy parameters ...

Cellular-Automata model for dense-snow avalanches [PDF]

open access: yes, 2007
This paper introduces a three-dimensional model for simulating dense-snow avalanches, based on the numerical method of cellular automata. This method allows one to study the complex behavior of the avalanche by dividing it into small elements, whose ...

Grasshoppers’ adaptation to elevated radioactivity in the Chernobyl exclusion zone [PDF]

open access: yes, 2013
The explosion of the Chernobyl nuclear power plant in 1986 was categorized as the most severe nuclear accident in history, resulting in some of the most radioactively contaminated habitats on Earth. The consequence was an increased mutation and mortality rate in biota, which caused major damage on the ecosystem level, observed as local extinction and ...

Zones of Parallel Lines of Elevation in the Earth's Crust [PDF]

open access: yesNature, 1874
HE is a bold man who will predicate that no future discovered fact will disturb even the most widely accepted hypothesis. This being so, all hypotheses being in fact tentative only, and valuable in so far as they enable us to classify and deduce laws from such facts as we know, we ought to welcome every generalisation which groups known facts under ...

Controlling Factors of the Spatial‐Temporal Fluctuations in Evapotranspiration Along an Elevation Gradient Across Humid Montane Ecosystems

open access: yesWater Resources Research, 2023
Diverse meteorological and vegetation conditions at different elevations and years lead to varied contributions of evapotranspiration (ET) to water yield in montane areas. However, how physical and biological factors affect interannual and elevational ET

Wave attenuation in mangrove forests; field data obtained in Trang, Thailand [PDF]

open access: yes, 2012
Mangroves thrive in sheltered intertidal areas in the tropics and sub-tropics. Due to this position at the interface between land and sea, mangroves play an important role in the attenuation of waves.

Preliminary Evaluation of AIS Spectra Along a Topographic/moisture Gradient in the Nebraska Sandhills [PDF]

open access: yes, 1985
Six spectral plots, each summarizing single-pixel reflectance for 128 channels of Airborne Imaging Spectrometer (AIS) data, were examined. The six sample pixels were located along a topographic/moisture gradient from lake surface to dune top in the ...

Dexamethasone for Chemotherapy‐Induced Nausea and Vomiting Prevention in Pediatric Patients: International Consensus

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background An international Delphi panel of experts developed consensus statements to delineate the circumstances where the risks of dexamethasone as an antiemetic do and do not outweigh its benefits. Procedure Experts in supportive care of pediatric patients were invited to participate.

Ant Diversity Declines with Increasing Elevation along the Udzungwa Mountains, Tanzania

open access: yesDiversity, 2022
Biodiversity patterns along elevational gradients are generally characterised by monotonic decreases or mid-elevational peaks in species richness, while elevational zones may be characterised by distinct assemblages, or higher zones may be subsets of ...

Two-sided asymmetric subduction; implications for tectonomagmatic and metallogenic evolution of the Lut Block, Eastern Iran [PDF]

open access: yes, 2011
West directed subduction zones show common characteristics, such as low structural elevation, deep trench, steep slab and a conjugate back-arc basin that are opposite to those of the east directed subduction zones.
