“…Subsequently, the resistance surface was merged with the buffer zone, and finally, the combined resistance surface and the randomly selected patches were input into the software for calculation ( Koen et al., 2014 ). The pairwise mode and the eight-neighborhood method were used to match the patches which were selected randomly in pairs and input into the Circuitscape software to perform the calculation ( McLean and Rubio, 2022 ). After the generation of the current density map, the pre-established buffer area outside the study area is clipped to focus on the analysis of the currents within the study area.…”

Effect of fencing on regional ecological networks in the northern Tibetan Plateau

Fencing is an essential measure for the rehabilitation and conservation of grasslands on the Qinghai-Tibet Plateau. However, its construction could change the distribution and migration of wildlife, thus affecting the integrity of the ecological networks for local wild animal movement. It is of great significance to quantify the potential impact of fencing on ecological network connectivity associated with land-use changes at regional scale. In this study, taking the northern Tibetan Plateau as the study area, we explored the ecological network change using circuit theory approach under different scenarios at county scale. Among them, this study set up four different scenarios according to the economic growth rate, population growth rate and the sustainable development of society and environment. The results showed that: 1) with increased grazing intensity and enhanced human activities from 1990 to 2015, the grasslands of the northern Tibetan Plateau were greatly degraded, most of which was converted into the barren land, and the conversion proportion was as high as 90.84%, which lead to a decreasing trend of the current density of ecological network in most counties and deterioration of ecological connectivity; 2) fencing construction has reduced regional current density, while fencing intensity is positively correlated with current density loss at county scale. Among them, the counties with serious current density loss were distributed in the northwest and southeast regions. The maximum loss ratio is 39.23%; 3) under four different future land use scenarios, coordinated economic, social and environmental development will have a positive effect on the ecological network. The results of the study have important ecological significance for developing reasonable conservation measures for grassland restoration, protecting wildlife, and maintaining regional ecological balance.

“…The analysis of the patterns of potential movement across the site were performed with Omniscape On the Periphery of the Inka Empire electronic circuit theory, where movement is analysed as electrical current and friction as electrical resistance. Circuitscape has been used in archaeology in the past as an alternative to the widespread Least Cost Paths, since it produces an overview of connectivity beyond optimality and specific locations (Howey 2011;McLean & Rubio-Campillo 2022). In turn, Omniscape 2 (McRae et al 2016) expands on this by offering a unique approach to connectivity modelling, enabling the sources, destinations and intensity of movement (modelled as electrical current) to be informed by continuous spatial data.…”

This paper describes the analysis of the Late Prehispanic rock-art site of Villavil 2 (Catamarca, Argentina). Despite its modest and inconspicuous nature, this is one of the few examples of rock-art sites known in the area to date. The relationship of the site with the surrounding landscape and the distribution of rock art throughout the site are analysed using a combination of GIS and 3D modelling. This analysis makes it possible to gain an understanding of the factors behind the location and distribution of rock art on different spatial scales. The interpretation presented here suggests that this rock art reproduces, on a modest local scale, patterns of production of Inka landscapes of control and dominion that have been recognized elsewhere, in sites with a much more obvious monumental scale. The internal organization of the site mimics, on a small scale, forms of interaction with the wider landscape that have been regionally observed, usually focusing on more conspicuous elements such as architecture.

“…These add another view to the Euclidean distance measurements that form the basis of the land suitability modelling of zones. This is important because Euclidean distance measurements are heavily criticised for not representing internal structures appropriately due to not being able to cope with the impact of relative relationships between the loci (Gutiérrez & García-Palomares 2008;McLean & Rubio-Campillo 2022;Nicholls 2001). This work builds on land suitability modelling, which centers on modelling the external shapes of space -the exohulls of space (i.e.…”

Exploratory GIS models present multiple different conceptual versions of space. This article focusses on the landscape level pathways between areas defined as suitable for land use and occupancy within the Willandra Lakes Region World Heritage Area (WLRWHA), New South Wales (NSW), Australia. Models of the potential connections between ecologically significant land use patches and key hydrology provide iterative networks of functional connectivity, highlighting salient pathways of past land use and occupancy of Country. The shape of the connections between places is important to understanding Country from the inside. Outputs from these network models are a powerful visualisation tool because they display areas where contact with the 19 th c Europeans, particularly through fence construction and ground water appropriation, caused greater levels of exploitation and damage than currently recognised. Concomitantly, the benefit of situating these network techniques within an exploratory framework cannot be understated. The iterative nature of the exploratory design allows for multiple presentations of the connectivity between the spaces within the WLRWHA and therefore multiple ways of knowing and seeing space. Modelling the potential pathways between suitable patches opens the door to discussions about the diverse possible corridors of activity within pre-European settlement of Country and the corollary discussion of how European settlement substantially impacted upon these connections and continues to impact on a living Country.
