Role of the Colored Noise in Spatio-Temporal Behavior of Two Competing Species [PDF]

open access: yes, 2005
We study the spatial distributions of two randomly interacting species, in the presence of an external multiplicative colored noise. The dynamics of the ecosystem is described by a coupled map lattice model.

Fishermen Follow Fine-Scale Physical Ocean Features for Finance

open access: yesFrontiers in Marine Science, 2018
The seascapes on which many millions of people make their living and secure food have complex and dynamic spatial features—the figurative hills and valleys—that influence where and how people work at sea.

Behavioral responses to spatial variation in perceived predation risk and resource availability in an arboreal primate

open access: yesEcosphere, 2022
Prey species must often face a trade‐off between acquiring resources and minimizing predation risk. The spatial variation in predation risk across a landscape, as perceived by prey across their foraging or home range, creates a “landscape of fear” by ...

Linking Terrestrial and Aquatic Biodiversity to Ecosystem Function Across Scales, Trophic Levels, and Realms

open access: yesFrontiers in Environmental Science, 2021
Global declines in biodiversity have the potential to affect ecosystem function, and vice versa, in both terrestrial and aquatic ecological realms. While many studies have considered biodiversity-ecosystem function (BEF) relationships at local scales ...

On spatial behavior of the solution of a non-standard problem in linear thermoviscoelasticity with voids

open access: yesArchives of Mechanics, 2015
In this paper we study the constrained motion of a prismatic cylinder made of a thermoviscoelastic material with voids and subjected to final given data that are proportional, but not identical, to their initial values.

Spatial biases in viewing behavior

open access: yesJournal of Vision, 2014
Viewing behavior exhibits temporal and spatial structure that is independent of stimulus content and task goals. One example of such structure is horizontal biases, which are likely rooted in left-right asymmetries of the visual and attentional systems. Here, we studied the existence, extent, and mechanisms of this bias. Left- and right-handed subjects

The shuttle migration with regard to social potential of rural settlements (case study)

open access: yesAgricultural Economics (AGRICECON), 2004
This article concerns shuttle migration activities of rural inhabitants and at the same time asks how this phenomenon influences social potential of rural settlements. The authors draw on the social ecology.

Predicting bird diversity through acoustic indices within the Atlantic Forest biodiversity hotspot

open access: yesFrontiers in Remote Sensing, 2023
The increasing conversion of natural areas for anthropic land use has been a major cause of habitat loss, destabilizing ecosystems and leading to a biodiversity crisis.

Survey on Modeling Method of Spatial Cooperative Behavior of Swarm Robots [PDF]

open access: yesJisuanji kexue yu tansuo, 2022
Swarm robots are composed of a certain number of physical robots. Through interaction and cooperation, individuals in this kind of system can sprout robust, scalable and flexible swarm intelligence behavior.
