Landscape Heterogeneity and Dynamics

2019
Abstract Heterogeneity is a defining characteristic of landscapes and therefore central to the study of landscape ecology. Landscape ecology investigates what factors give rise to heterogeneity, how that heterogeneity is maintained or altered by natural and anthropogenic disturbances, and how heterogeneity ultimately influences ...

[Review on landscape heterogeneity].

Ying yong sheng tai xue bao = The journal of applied ecology, 2002
On the base of precedent studies, the occurring mechanism, classification, measurement methods, and the important role of landscape heterogeneity in landscape ecology were reviewed. The inner and outer uncertain factors result in landscape heterogeneity.

Heterogeneity of Thalamic Input Landscapes

2023
Abstract Unlike cortical neurons, thalamocortical neurons are not connected to each other via a rich recurrant collateral system. As a consequence, thalamic computation is dominated by the integration of extrinsic inputs, not by the interactions among intrinsic elements.

Coexistence and Spread of Competitors in Heterogeneous Landscapes

Bulletin of Mathematical Biology, 2010
Competition between species is ubiquitous in nature and therefore widely studied in ecology through experiment and theory. One of the central questions is under which conditions a (rare) invader can establish itself in a landscape dominated by a resident species at carrying capacity. Applying the same question with the roles of the invader and resident

The Brain’s Heterogeneous Functional Landscape

Philosophy of Science, 2015
Multifunctionality poses significant challenges for human brain mapping. Cathy Price and Karl Friston argue that brain regions perform many functions in one sense and a single function in another. Thus, neuroscientists must revise their “cognitive ontologies” to obtain systematic mappings.

Predicting Forest Microclimate in Heterogeneous Landscapes

Ecosystems, 2009
Forest microclimate plays an integral role in ecosystem processes, yet a predictive understanding of its spatial and temporal variability in heterogeneous landscapes is largely lacking. In this study, we used regression kriging (RK) to analyze the degree to which physiographic versus ecological variables influence spatio-temporal variation in ...

Heterogeneous Landscape of Grassroots Initiatives

2017
In response to the controversies around “civil society” in the Russian context, this chapter sheds light on the heterogeneous landscape of civic activism in the politico–military sphere of the country. The chapter notably addresses the severe crisis faced by Russian civic activists today.

Landscape heterogeneity and plant diversity in agricultural landscapes

2019
Landscape heterogeneity is now widely recognized as a key determinant of biodiversity. Defined by its composition (amount and diversity of habitats) and configuration (spatial arrangement of habitats), landscape heterogeneity is a fundamental concept in landscape ecology.
