Present biogeomorphic knowledge supports the hypothesis that abiotic-biotic feedbacks create characteristic modulated patterns of earth surface landforms, adjusting according to biological evolution in the long term and to ecological succession
in the short term. In this context, natural selection of organisms and ecological successions are considered to have the potential, in some cases, for extension to the physical world, including earth surface landforms. The extended evolutionary perspective
, that is intended to feed back to ecology and evolutionary biology, indicates the potential for change in the deep understanding of geomorphology to reflect evolutionary and ecological succession theories.

Protection of ecological corridors in spatial planning documents in Poland implementation problems
The paper discusses main theoretical and methodological assumptions regarding designation of ecological corridors and determination of their boundaries. It presents a review of concepts of ecological corridors prepared in Poland and draws attention
to the lack of legal instruments, which would ensure ecological network continuity. The paper discusses the state and scope of works on the implementation of the concept of the Lublin Ecological Network in updated spatial development plan of the Lublin

This review outlines the key changes in issues of equilibrium in ecosystems and the emergence of spatial ecology, and attempts to link the two. Although the issues considered are not solely limited to ecology (for example the consideration of space
in hydrological models has paralleled developments in ecological models) they are considered here in that light and especially within the context of landscape and disturbance ecologies.

Cleaning up after the Celtic Tiger : scalar fixes in the political ecology of Tiger economies

, the concepts of scalar strategies and struggles over scale may prove useful. Ecological projects too are fundamentally produced by and implicated in the structuration of scale. In calling for dialogue between political ecological studies and recent work
in geography, the paper hopes to contribute towards the development of a political ecology of Tiger states.

The urban political ecology of post-industrial Scottish towns : examining Greengairs and Ravenscraig

This article examines the urban political ecology of post-industrial Scottish towns (Greengairs and Ravenscraig) with the goal of unravelling the understanding and the coping mechanisms of environmentally deprived residents. The towns are permeated
by a widespread, often dissimulated, political ecology that is nonetheless always present. Empirical results demonstrate that a more comprehensive handling of the political ecology of the urban is crucial in order to halt the sources of marginalisation
and ecological degradation.

Effectiveness of ecological units for stratification of bird habitat in Yukon-Charley Rivers National Preserve, Alaska
Alaska ; Bird ; Ecological inventory ; Ecology ; Fauna ; Habitat ; National park ; Vegetation
Point-count data from the bird inventory were used to test the ability of the ecological units to fine-scale vegetation types. The ecological units were a synthesis of geology, landforms, soils, and vegetation mapped at a scale of 1:250,000
; the vegetation types were based on vegetation within 50 m of the sample points. Nonparametric multivariate statistical tests showed that both ecological units and vegetation types provide useful and complementary information about bird habitat selection
. Ecological units have several advantages over vegetation types as sample-area strata.
