Persistence without prosperity at the upper range margin: Elevation, microhabitat buffering and biotic pressure in a range‐expanding spider

open access: yesEcological Entomology, EarlyView.
Anthropogenic linear features facilitate high‐elevation colonization. Parasitoid pressure declines markedly with elevation. Cocoon damage increases despite reduced parasitism at high elevation. Abstract The upper elevational range limits of thermophilic arthropods reflect constraints on population persistence rather than simple presence.

Navigating Inter‐Municipal Collaboration Challenges: 'In‐Tensions' in Shared Service Center and Joint Venture Arrangements

open access: yesFinancial Accountability &Management, EarlyView.
ABSTRACT Municipal collaborations such as shared service centers and joint ventures are widely promoted as ways to strengthen local service capacity. Yet they often develop in uneven and sometimes unstable ways. This paper examines why arrangements built on similar institutional promises take such different trajectories in practice.

Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

open access: yesIbis, EarlyView.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

Taxonomic, phylogenetic and functional diversity patterns of Saturniidae moth communities along a tropical forest recovery gradient in Ecuador

open access: yesInsect Conservation and Diversity, EarlyView.
Diverse Saturniidae moth communities are found in naturally recovering tropical forests in Ecuador. Community composition showed a gradual turnover with strongest differences between old‐growth forest and active agriculture, but only weak differences in taxonomic, phylogenetic and functional diversity. While our results suggest that Saturniidae are not

Understanding Responsible Innovation in Small Producers’ Clusters in  Vietnam through Actor Network Theory (ANT)

open access: yes, 2013
There is increasing evidence that innovation offers perspectives for poverty alleviation in small producers’ contexts in developing countries. However, innovations sometimes imply additional harmful environmental and social consequences, which are not in line with broader poverty alleviation and sustainable development notions.
