Tundra vegetation community, not microclimate, controls asynchrony of above and belowground phenology

The below-ground growing season often extends beyond the above-ground growing season in tundra ecosystems. However, we do not yet know where and when this occurs and whether these phenological asynchronies are driven by variation in local vegetation communities or by spatial variation in microclimate. Here, we combined above- and below-ground plant phenology metrics to compare the relative [...]

Faster than expected: Release of nitrogen and phosphorus from decomposing wood

Baptiste Joseph Wijas, William K Cornwell, Jeff R Powell, et al.

● Deadwood represents globally important carbon, nitrogen, and phosphorus pools. Current wood nutrient dynamics models are extensions of those developed for leaf litter decomposition. However, tissue structure and dominant decomposers differ between deadwood and litter, and recent evidence suggests that decomposer stoichiometry in combination with litter quality may affect nutrient [...]

Allelopathy-selected microbiomes mitigate chemical inhibition of plant performance

Allelopathy is a common and important stressor that shapes plant communities and can alter soil microbiomes, yet little is known about the direct effects of allelochemical addition on bacterial and fungal communities or the potential for allelochemical-selected microbiomes to mediate plant performance responses, especially in habitats naturally structured by allelopathy. Here we present the first [...]

Solar radiation drives potential demographic collapse in a perennial bunchgrass via dramatically reduced seedling establishment

Many perennial plants in semi-arid rangelands have experienced population declines, and understanding the ecological and demographic processes behind these declines is important to slowing or reversing them. Although anthropogenic disturbances drive many declines, other sorts of environmental variability, such as the differences in solar radiation with aspect, may impact population success [...]

Plant families exhibit unique geographic trends in C4 richness and cover

Numerous studies have analysed the relationship between C4 plant cover and climate. However, few have examined how different C4 taxa vary in their response to climate, or how environmental factors alter C4:C3 abundance. Here we investigate (a) how proportional C4 plant cover and richness (relative to C3) responds to changes in climate and local environmental factors, and (b) if this response is [...]

The Global Forest Health Crisis: A Public Good Social Dilemma in Need of International Collective Action

Society is confronted by interconnected threats to ecological sustainability. Among these is the devastation of forests by destructive non-native pathogens and insects introduced through global trade, leading to the loss of critical ecosystem services and a global forest health crisis. We argue that the forest health crisis is a public good social dilemma and propose a response framework that [...]

ausplotsR: An R package for rapid extraction and analysis of vegetation and soil data collected by Australia’s Terrestrial Ecosystem Research Network

The Terrestrial Ecosystem Research Network (TERN), Australia’s national land ecosystem monitoring program, measures critical environmental attributes from local to continental scale and generates quality data for research and land management. Since 2011, TERN has performed standardised field surveys and sampling across a national plot network. At each plot, TERN records vegetation structure, [...]

Predicting tropical tree mortality with leaf spectroscopy

Do tropical trees close to death have a distinct leaf spectral signature? Tree mortality rates have been increasing in tropical forests globally which is reducing the global carbon sink. Upcoming hyperspectral satellites could be used to predict regions close to experiencing extensive tree mortality during periods of stress like drought. Here we show how imminent tropical tree mortality in [...]
