The influence of arbuscular mycorrhizae on the relationship between plant diversity and productivity
Old-field plant species richness in the presence and absence of two species of AMF is found to be consistent with the hypothesis that AMF increase the redundancy of plant species in the productivity of plant communities, and indicates that these symbionts must be considered in future investigations of plant biodiversity and ecosystem function.

Historical ecology: using unconventional data sources to test for effects of global environmental change.
The strengths and weaknesses of four unconventional sources of historical ecological data are reviewed: land survey records, "legacy" vegetation data, historical maps and photographs, and herbarium specimens, to understand the impacts of habitat disturbance and climate change on plant populations and communities.

Quantifying temporal change in biodiversity: challenges and opportunities
This work explores methods of quantifying change in biodiversity at different timescales, noting that autocorrelation can be viewed as a feature that sheds light on the underlying structure of temporal change. Expand
Gains in native species promote biotic homogenization over four decades in a human‐dominated landscape
It is shown that human-mediated disturbance is the dominant driver of plant community changes, but the net result has actually been an increase in richness, for each plot and for all plots pooled, and for both natives and exotics, despite a decline in variability among plant communities on the landscape.

Threats to Canadian species at risk: An analysis of finalized recovery strategies
In order to reverse the decline of imperilled species, we need to know what is threatening their survival. Canada’s Species at Risk Act (SARA) is intended to provide for the protection and recoveryExpand
Plant Biodiversity Change Across Scales During the Anthropocene.
At the local scale, conversion of primary vegetation to agriculture has decreased plant diversity, whereas other drivers of change-e.g., climate warming, habitat fragmentation, and nitrogen deposition-have highly context-dependent effects, resulting in a distribution of temporal trends with a mean close to zero.

Species of arbuscular mycorrhizal fungi affect mycorrhizal responses to simulated herbivory
This AMF × clipping interaction indicates that it is difficult to generalize on the effects of herbivory on plant and fungal responses, even when dealing with the same plant species. Expand
Multidisciplinary synthesis of long-term human–ecosystem interactions: A perspective from the Garry oak ecosystem of British Columbia
It is argued that delving into the long-term history of a system by compiling research from multiple disciplines helps ecologists to understand the key drivers of ecosystem structure and dynamics, including the role of humans. Expand
Combining phytolith analysis with historical ecology to reveal the long-term, local-scale dynamics within a savannah-forest landscape mosaic
An understanding of the historical range of variability of an ecosystem can improve management and restoration activities, but this variability depends on the spatial and temporal scale at which itExpand
