Structural Intuition and Creative Play: An Architectural Perspective to Shell Pedagogies [PDF]

open access: yes, 2016
The notions of structural intuition and creative play had been raised by particular structural artists (Billington, 1983 [1]). Professor Pier Luigi Nervi expressed the importance of Structural Intuition in his 1965 Elliot Norton Lectures at Harvard ...

Functional diversity in agricultural landscapes: evidence of long‐term clustering and multi‐scale effects of land use on avian communities

open access: yesOikos, EarlyView.
Functional diversity (FD) is an essential community property connecting biodiversity, ecosystem functioning, and conservation objectives. In agricultural landscapes, avian communities, which play key functional roles, are facing large‐scale biodiversity erosion, largely due to land‐use changes.

Partial recovery of large seed arrival following ecological restoration in fragmented tropical rainforests

open access: yesOikos, EarlyView.
Forest restoration success depends crucially on the reinitiation of ecological processes such as seed arrival that drive natural regeneration. We know little about whether, by increasing and diversifying local seed sources to alleviate seed limitation, and attracting animal frugivores to alleviate dispersal limitation, restoration could shift seed ...

The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

open access: yesPeople and Nature, EarlyView.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Understanding smallholder decision‐making to increase farm tree diversity: Enablers and barriers for forest landscape restoration in Western Kenya

open access: yesPeople and Nature, EarlyView.
Abstract Integrating diverse trees and shrubs (hereafter ‘trees’) in agricultural landscapes has emerged as a crucial nature‐based solution to the triple challenge of biodiversity loss, climate change and food security. The potential benefits of on‐farm trees for both people and nature, however, are often constrained by inadequate consideration of ...

Mechanical characterization of timber in structural sizes: bending and compression tests [PDF]

open access: yes, 2005
This paper presents the results obtained in a series of tests on Pinus Pinaster Ait. timber specimens, using the prEN408:2000, to estimate the local and global Young’s modulus and strength both in bending and compression parallel to the grain.

How uneven access shapes the socio‐economic and environmental potential of game meat value chains: The case of legal game meat in Zambia

open access: yesPeople and Nature, EarlyView.
Abstract Game meat contributes to human nutrition, food security and sociocultural practices around the world. Game meat also comes with risks, including overharvesting and zoonotic and food‐borne disease. These may be pronounced where game meat travels along complex value chains from rural to urban areas.
