Transforming Management Education: Insights from Social‐Ecological Systems and Social Innovation Research

Journal of Management Studies, EarlyView.
Abstract It is clear that contemporary management education (ME) needs to be transformed to tackle complex social‐ecological crises effectively. However, the concept of transformation is often ill‐defined in the context of ME; while there is also a lack of understanding about what concrete transformation trajectories (also called scaling pathways) are ...

Balancing Risk and Reward: Red Fox Exploitation of Kill Sites in a Wolf‐Occupied Landscape

Journal of Zoology, EarlyView.
Wolves are recolonising the European Alps, and the carcasses they leave behind are a valuable food source for smaller carnivores. Using camera traps at 26 wolf‐killed red deer carcasses in Stelvio National Park, we found that red foxes visited every carcass and timed their visits according to how much meat was left, rather than to whether wolves were ...

Ecological and genomic variation in ectomycorrhizal fungal exploration types

New Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EMF) produce mycelia with variable extension and complexity, which can be classified according to soil ‘exploration types’ (ETs). ETs have received attention as one of the few mycorrhizal trait frameworks, but without an empirical classification of ET functional diversity and environmental preferences, understanding and ...

Fluctuation of Picea timberline and paleo-environment on the northern slope of Tianshan Mountains during the late Holocene

, 2006
As a good indicator of Holocene climate, the fluctuation of alpine timberline is a synthetical result of impacts of many environmental factors during geological and historical periods and modern times.

A novel method based on high‐resolution imaging spectroscopy to predict fine‐root traits and the economics space of fresh tree roots

New Phytologist, EarlyView.
Maps of the estimated root nitrogen concentration in the < 0.5‐mm‐diameter classes of 20 woody species based on the imaging spectroscopy using the shortwave infrared spectral region. Summary Tree fine‐root morphological, anatomical, and chemical traits are important to reflect belowground resource acquisition strategies to support tree growth, but ...

The roads most traveled: genetic convergence in plant repeated evolution

New Phytologist, EarlyView.
Observation of a genotype–phenotype association in a focal lineage (magnifying lens) provides a starting point for predicting homolog reuse during repeated trait evolution. This review suggests that the likelihood that mutations in homologous genes contribute to similar phenotypes in other lineages depends on both mutational effect stability (MES) and ...

Forest under stress: responses and recovery of water relations across scales during the compound drought in summer 2022

New Phytologist, EarlyView.
A schematic showing the links of tree‐scale (root‐, stem‐, and leaf‐level) and ecosystem‐scale water relations during the CSAD at CH‐Lae. Summary The summer of 2022 was characterized by compound soil and atmospheric drought (CSAD; low soil water content, SWC, and high vapor pressure deficit, VPD) in Central Europe, threatening forest carbon ...
