Taxon‐dependent multisite species turnover in fragmented habitats: comparing zeta diversity across birds, butterflies, and cursorial hunting spiders

open access: yesEcography, EarlyView.
Habitat fragmentation alters species diversity and reshapes community composition. However, conventional pairwise approaches to compositional variation (i.e. beta diversity metrics) do not explicitly characterize how species sharing or turnover change with the number of habitat patches.

Global patterns of treeline predictability and the gap between the forest and the treeline

open access: yesEcography, EarlyView.
The alpine treeline is the highest elevation at which trees can grow, which is assumed to be controlled by temperature and globally predictable. However, many upper forest limits (UFLs) do not reach this elevation, due natural factors and human disturbance.

Terrain classification in complex three-dimensional outdoor environments

open access: yes
This paper presents two techniques to detect and classify navigable terrain in complex three-dimensional (3D) environments. The first method is a low level on-line mechanism aimed at detecting obstacles and holes at a fast frame rate using a time-of ...

Ocean Governance and Marine Conservation: Institutional Work as a Lever for Ocean Sustainability

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Ocean governance presents one of the most complex environmental policy challenges of our time, requiring coordinated action across multiple scales, sectors and stakeholder groups. This paper applies institutional work theory to systematically examine how actors create, maintain and disrupt the governance arrangements underpinning ocean ...

Transformative, Iterative or Performative? Conceptualising Patterns of Fossil Fuel Phaseout Leadership

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Global leadership in phasing out fossil fuels is an important new frontier in climate governance, yet remains undertheorised within existing scholarly accounts of climate leadership. In this paper, we argue that ‘phaseout leadership’—climate leadership centred on curtailing fossil fuel supply—is a distinct kind of leadership that dominant ...

The Crowd: Zooming in on Social Behaviour

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT The direct observation of social behaviour has almost completely vanished from socialpsychological research, in favour of studies of attitudes, identities and cognitions. Using crowd psychology as an illustration, this article argues for a renewed focus on observational research enabled by recent technological advances, including high ...
