“…The final dimension, the intrinsic scale, is the scale at which ecological phenomena interact with the environment and is an emergent property of an organism's response to its environment, which is measured indirectly at the observation scale(s) and/or analysis scale(s) [2,29,35]. In this paper we focus primarily on observation scale effects from changing spatial and thematic resolution in the context of GIS analysis using data derived from remote sensing.…”

“…However, a recent study by Kendall et al [50] using this multi-scale buffer analysis method showed that patterns of r 2 values for a range of buffer sizes changed with thematic resolution and spatial resolution (defined by the minimum mappable unit). Additionally, Lechner et al [29] using synthetic analysis showed that the highest r 2 values may incorrectly identify intrinsic scales identified with multi-scale buffer analyses as a result of changes in pixel size and applying a smoothing filter (which also reduces spatial resolution).…”

“…In remote sensing, spatial resolution is primarily a product of the pixel size of the sensor or the object-scale for data produced through geographic object-based image analysis [22][23][24][25][26]. Pre-and post-processing of spatial data, commonly used for improving classification and geometric accuracy, also affects spatial resolution through: removing features below a minimum area (minimum mappable unit) [27,28], the application of smoothing filters [29] and the characteristics of the remote sensing device [30].…”

In this review we examine the past 5 years of landscape ecology research examining the effects of both spatial and thematic resolution on ecological analysis. While spatial resolution has been a topic of research for many decades, scale effects from thematic resolution have only recently been studied. Recent multi-scale analyses have demonstrated that the effects of thematic resolution on ecological analysis are comparable to spatial resolution and both spatial and thematic resolution interact. Additionally, spatial and thematic resolution can impact on multi-scale methods that are commonly used to identify the intrinsic scale-the scale at which ecological phenomena interact with the environment. A key aim of multi-scale analysis in landscape ecology is to characterise the scale-dependency of ecological processes, however, the interdisciplinary nature of landscape ecology means that research on scale has incorporated methods from a range of disciplines. These methods and concepts include: 1) multi-scale methods which characterise the sensitivity of an analysis to the modifiable areal unit problem, 2) spatial statistics for characterising the scale dependency of landscape patterns and identifying the optimal scale and 3) ecological theory describing intrinsic scales/domains of scales. We conclude by drawing on the existing literature to describe potential future areas of research to address the impacts of spatial and thematic resolution. We suggest further research on the effects of thematic resolution and conceptualising the scale continuum as multi-dimensional. We also identify mechanistic models and spatial statistics as a promising direction for future research.

“…This is not only an issue for spatial scale, but for temporal scales as well (Modifiable Temporal Unit Problem [MTUP]) [31]. We suspect that the MAUP is more prevalent in most map classifications, such as the PMM [32]; however, to date this has not been tested. One potential solution to the MAUP is to incorporate random effects of space into a mixed-effects model, especially if the factors leading to spatial heterogeneity are unknown [30].…”

Purpose of Review We review and provide comment on issues of scale in ecological studies in the context of two paradigms used to define landscapes: the patch-mosaic and gradient models. Our intent is to offer guidance for structuring habitat-selection models with examples of how scale, autocorrelation, measurement error, and choice of patch-mosaic or gradient models, analysis methods, and covariates by the researcher can influence inferences regarding landscapeorganism interactions. Recent Findings Methods that allow the organism or data to define the grain and extent of scale of the study offer promise by reducing subjectivity in choices of scale. Ultimately, we recommend that the ecological phenomenon of interest should shape the selection of models defining landscape-organism interaction; however, the choice of model remains with the researcher and is dependent on the research question and the availability of data. Clearly, both the patch-mosaic and gradient models can provide reasonable frameworks for study, and multiple scales that draw from both paradigms often may be most appropriate. Summary Scale has been identified as a crucial feature of landscape ecology, yet scale as a paradigm has offered little direction for ecologists. Likewise, debate contrasting gradient models and patch-mosaic models offers few new insights on how ecologists might decide on an appropriate scale for analysis of organism distribution or habitat selection. Various ecological processes influence organisms at different scales and modeling approaches need to be able to accommodate multiple scales simultaneously, which may vary by landscape structure and movement ecology. The continuum of scales and combinations of both gradient and patch-mosaic landscapes provides the necessary array of structures that can be used to construct combinations of landscape covariates that coincide with the ecology of the organism across scales.

“…Entretanto, outros traços biológicos das espécies, por exemplo, a área de vida (Bowman et al, 2002), podem fazer com que a escala em que a estrutura da paisagem mais influencia cada espécie seja ligeiramente diferente (Jackson e Fahrig 2015 A utilização de mapeamentos com resoluções inadequadas pode fazer com que as escalas apropriadas das respostas das espécies em relação ao ambiente sejam identificadas erroneamente (Lechner et al 2012), influenciar a força da relação entre a resposta ecológica da espécie e a variável preditora (Turner et al 2001;Lechner et al 2012), além de poder causar uma mudança na direção das relações (Turner et al 2001).…”
