The impact of urbanisation on social behaviour: a comprehensive review

open access: yesBiological Reviews, EarlyView.
ABSTRACT Urbanisation is a key driver of global environmental change and presents animals with novel stressors and challenges. It can fundamentally influence social behaviour and has the potential to reshape within‐ and between‐species social interactions. Given the role of social behaviour in reproductive fitness and survival, understanding how social

Upper Bound Finite Element Limit Analysis for Problems of Reinforced Earth, Unsupported Tunnels and a Group of Anchors [PDF]

open access: yes, 2013
This thesis presents the implementation of the upper bound limit analysis in combination with finite elements and linear optimization for solving different stability problems in geomechanics under plane strain conditions.

Continual decision‐making dynamics across biological organisms

open access: yesBiological Reviews, EarlyView.
ABSTRACT Decision‐making is a central function of adaptive behaviour in biological agents. However, strategies for adaptive decision‐making can vary substantially across species. Here, we aim to extend the comparative scope of decision‐making analyses to phylogenetically diverse organisms.

Investigating Soil Adhesion and Antiadhesion Performance of Nonsmooth Subsoiler Surfaces

open access: yesJournal of Engineering
Soil adhesion is one of the main factors affecting the working resistance and energy consumption of agricultural machinery. Many scholars have been doing much research on the method of soil antiadhesion, but the conditions for the occurrence of adhesion ...

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Post-stressed concrete foundation may reduce machinery vibration [PDF]

open access: yes, 1967
Post-stressing concrete mat foundation reduces excessive vibrations in machinery. The mat is stressed in compression after the machinery is mounted, thus closing any cracks in it, altering the distribution of the soil subgrade reaction on the mat, and ...

Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Spatial metrics in fire ecology: seeking consistency amidst complexity

open access: yesBiological Reviews, EarlyView.
ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

Examining the swelling potential of cohesive soils with high plasticity according to their index properties using GIS

open access: yesOpen Geosciences
As the value ranges presented in the literature with tables and graphs that feature soil index properties related to the soil swelling potential are intertwined, their interpretation may pose certain challenges.
