Delimitation of landscape units treated as estimation fields in the modelling of a landscape system

open access: yesMiscellanea Geographica: Regional Studies on Development, 2013
The main objective of this paper is to represent the hierarchical structure of an environment by using two concepts: typology and regionalization. The Płock Region (1,766.95 sq. km) and transect crossing this area (796.2 sq. km) is the research location.

Monitoring Forest Change in Landscapes Under-Going Rapid Energy Development: Challenges and New Perspectives

open access: yesLand, 2014
The accelerated development of energy resources around the world has substantially increased forest change related to oil and gas activities. In some cases, oil and gas activities are the primary catalyst of land-use change in forested landscapes.

Energy Landscape and Global Optimization for a Frustrated Model Protein [PDF]

open access: yes, 2011
The three-color (BLN) 69-residue model protein was designed to exhibit frustrated folding. We investigate the energy landscape of this protein using disconnectivity graphs and compare it to a Go model, which is designed to reduce the frustration by ...

Disease outbreak thresholds emerge from interactions between movement behavior, landscape structure, and epidemiology

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2018
Significance Understanding how emerging infectious and zoonotic diseases spread through space and time is critical for predicting outbreaks and designing interventions; disease models are important tools for realizing these goals.

Complementarity between Textural and Radiometric Indices From Airborne and Spaceborne Multi VHSR Data: Disentangling the Complexity of Heterogeneous Landscape Matrix

open access: yesRemote Sensing, 2019
The quantitative characterization of landscape structure is critical to assess conservation, and monitor and manage biodiversity. The Mediterranean Basin is a biodiversity hotspot that illustrates the strong relationship between biodiversity and the ...

Honeybee foraging in differentially structured landscapes [PDF]

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 2003
Honeybees communicate the distance and location of resource patches by bee dances, but this spatial information has rarely been used to study their foraging ecology. We analysed, for the first time to the best of the authors' knowledge, foraging distances and dance activities of honeybees in relation to landscape structure, season and colony using a ...

Assessing Impacts of Urban Form on Landscape Structure of Urban Green Spaces in China Using Landsat Images Based on Google Earth Engine

open access: yesRemote Sensing, 2018
The structure of urban green spaces (UGS) plays an important role in determining the ecosystem services that they support. Knowledge of factors shaping landscape structure of UGS is imperative for planning and management of UGS.

The diverse structural landscape of quadruplexes [PDF]

open access: yesFEBS Letters, 2019
G‐quadruplexes are secondary structures formed in G‐rich sequences in DNA and RNA. Considerable research over the past three decades has led to in‐depth insight into these unusual structures in DNA. Since the more recent exploration into RNA G‐quadruplexes, such structures have demonstrated their in cellulo existence, function and roles in pathology ...

Aerial insectivorous bats in the Brazilian-Uruguayan savanna: Modelling the occupancy through acoustic detection

open access: yesFrontiers in Ecology and Evolution, 2022
The Pampa is the least protected and one of the least sampled for bats among the Brazilian domains. This leads to significant Linnean and Wallacean shortfalls for bats in the Brazilian-Uruguayan savanna ecoregion. Here, we aimed to model the occupancy of

Structure of the Energy Landscape of Short Peptides

open access: yes, 2002
We have simulated, as a showcase, the pentapeptide Met-enkephalin (Tyr-Gly-Gly-Phe-Met) to visualize the energy landscape and investigate the conformational coverage by the multicanonical method.
