Assessing spatial variability of soil macro fauna and tree canopy using fractal theory (Case study: Riparian Forest of Maroon River) [PDF]

open access: yesجغرافیا و پایداری محیط, 2016
1-Introduction Sustainability and maintenance of riparian vegetation or restoring of degraded sites is critical to sustain inherent ecosystem function and values. There is an increasing recognition of fundamental role of space in population.

Strahler Ordering Analyses on Branching Coral Canopies: Stylophora pistillata as a Case Study

open access: yesJournal of Marine Science and Engineering, 2022
The three-dimensional structural complexities generated by living sessile organisms, such as trees and branching corals, embrace distinct communities of dwelling organisms, many of which are adapted to specific niches within the structure.

Tropical Dry Forest Succession and the Contribution of Lianas to Wood Area Index (WAI) [PDF]

open access: yes, 2009
The transmission and interception of light through the canopy is an important indicator of forest productivity in tropical forest ecosystems, and the amount of light that eventually reaches the forest floor is influenced by its interactions with leaves ...

Preliminary Canopy Removal Experiments in Algal Dominated Communities Low on the Shore and in the Shallow Subtidal on the Isle of Man [PDF]

open access: yes, 1985
The algal dominated communities immediately above and below the low-water spring level on a moderately exposed Manx shore were investigated by canopy removal experiments. Fucus serratus, Laminaria digitata and L. hyperborea were removed.

From canopies to conversations: the continuing significance of "plausibility structures" [PDF]

open access: yes, 2018
Among the most generative – but oft-misunderstood – ideas found in Peter Berger’s magisterial work is the idea that religions depend on plausibility structures. This assertion points toward the social worlds in which religious ideas and practices take on

Modeling canopy-induced turbulence in the Earth system: a unified parameterization of turbulent exchange within plant canopies and the roughness sublayer (CLM-ml v0) [PDF]

open access: yes, 2017
Land surface models used in climate models neglect the roughness sublayer and parameterize within-canopy turbulence in an ad hoc manner. We implemented a roughness sublayer turbulence parameterization in a multilayer canopy model (CLM-ml v0) to test if ...

Response of soybean (Glycine max (L.) Merr.) to bacterial soil inoculants and foliar fertilization

open access: yesPlant, Soil and Environment, 2016
Soybean yields can be considerably improved by inoculation with selected Bradyrhizobium japonicum strains and foliar fertilization. An exact field experiment was carried out in 2012-2014 at the Experimental Station of Cultivar Assessment in Przecław ...

Canopy structural modeling using object-oriented image classification and laser scanning [PDF]

open access: yes, 2008
A terrestrial laser scanning (TLS) experiment was carried out in the EAGLE 2006 campaign to characterize and model the canopy structure of the Speulderbos forest. Semi-variogram analysis was used to describe spatial variability of the surface.

Improving competitive ability of chickpea with sowthistle [PDF]

open access: yes, 2005
An experiment was conducted to examine the extent of root and canopy interference of chickpea (Cicer arietinum L.) with sowthistle (Sonchus oleraceus L.). Sowthistle was surrounded with either two or eight chickpea plants.
