The Effect of Prior Viewing Position and Spatial Scale on the Viewing of Paintings [PDF]

open access: yesVision, 2023
The visual inspection of scenes is disrupted when participants are forced to begin inspection away from the centre of an image. The present study explored the effect of the starting point on the visual inspection of paintings. Eye movements were recorded

Determination of Spatial Scale in Martian Landscape Images Acquired by the Curiosity Rover, and Viewing Image Scale and Target Chemistry Using the ASIC Website

open access: yesEarth and Space Science, 2023
In this paper we describe a method to compute spatial scales for images acquired by NASA's Mars Curiosity rover (Mars Science Laboratory, MSL). The method is based on the assumption that the rover stands on an infinite plane that may have any orientation

A standardized and efficient technique to estimate seed traits in plants with numerous small propagules

open access: yesApplications in Plant Sciences, 2023
Premise Variation in seed traits is common within and among populations of plant species and often has ecological and evolutionary implications. However, due to the time‐consuming nature of manual seed measurements and the level of variability in imaging

Biogeographic multi‐species occupancy models for large‐scale survey data

open access: yesEcology and Evolution, 2022
Ecologists often seek to infer patterns of species occurrence or community structure from survey data. Hierarchical models, including multi‐species occupancy models (MSOMs), can improve inference by pooling information across multiple species via random ...

Disentangling the Ecological Processes Shaping the Latitudinal Pattern of Phytoplankton Communities in the Pacific Ocean

open access: yesmSystems, 2022
Phytoplankton diversity and community compositions vary across spaces and are fundamentally affected by several deterministic (e.g., environmental selection) and stochastic (e.g., ecological drift) processes.

The Effects of Spatial Resolution and Resampling on the Classification Accuracy of Wetland Vegetation Species and Ground Objects: A Study Based on High Spatial Resolution UAV Images

open access: yesDrones, 2023
When employing remote sensing images, it is challenging to classify vegetation species and ground objects due to the abundance of wetland vegetation species and the high fragmentation of ground objects.

Spatial and temporal scale framing of a decision on the future of the Mactaquac Dam in New Brunswick, Canada

open access: yesEcology and Society, 2017
Many large dams are coming to the end of their lifespans and decisions must be made about whether to rebuild/refurbish or remove them, which will have different implications across temporal and spatial scales.

Scale matters: a survey of the concepts of scale used in spatial disciplines

open access: yesEuropean Journal of Remote Sensing, 2019
Scale is a critical factor when studying patterns and the processes that cause them. A variety of approaches have been used to define the concept of scale but confusion and ambiguities remain regarding scale types and their definitions. The objectives of

Measuring Physical Neighborhood Quality Related to Health

open access: yesBehavioral Sciences, 2015
Although sociodemographic factors are one aspect of understanding the effects of neighborhood environments on health, equating neighborhood quality with socioeconomic status ignores the important role of physical neighborhood attributes.

Implementing the Western Gulf of Maine Area Closure: The Role and Perception of Fishers' Ecological Knowledge

open access: yesEcology and Society, 2012
The debate about the quality of fishers' ecological knowledge (FEK) and its value to fisheries management has long been present in the literature. This study sought to understand the role of FEK in a particular fisheries management decision in the U.S ...
