Disturbance history can increase functional stability in the face of both repeated disturbances of the same type and novel disturbances. [PDF]

Sci Rep, 2020
AbstractClimate change is expected to increase the incidences of extremes in environmental conditions. To investigate how repeated disturbances affect microbial ecosystem resistance, natural lake bacterioplankton communities were subjected to repeated temperature disturbances of two intensities (25 °C and 35 °C), and subsequently to an acidification ...

A history of concussions is associated with symptoms of common mental disorders in former male professional athletes across a range of sports [PDF]

, 2017
Objective: Recent reports suggest that exposure to repetitive concussions in sports is associated with an increased risk of symptoms of distress, anxiety and depression, sleep disturbance or substance abuse/dependence (typically referred as symptoms of ...

Interactive community responses to disturbance in streams: disturbance history moderates the influence of disturbance types [PDF]

Oikos, 2019
Both disturbance history and disturbance type act to structure communities through selecting for particular species traits but they may also interact. For example, flooding selects for species with flood‐resistant traits in streams, but those traits could make communities susceptible to other disturbances and so could cause shifts in community ...

Millennial-Scale Disturbance History of the Boreal Zone

, 2023
AbstractLong-term disturbance histories, reconstructed using diverse paleoecological tools, provide high-quality information about pre-observational periods. These data offer a portrait of past environmental variability for understanding the long-term patterns in climate and disturbance regimes and the forest ecosystem response to these changes ...

Phylogenetic signal in amphibian sensitivity to copper sulfate relative to experimental temperature [PDF]

, 2015
The release of large quantities of chemicals into the environment represents a major source of environmental disturbance. In recent years, the focus of ecotoxicology has shifted from describing the effects of chemical contaminants on individual species ...

Prunus serotina unleashed: invader dominance after 70 years of forest development [PDF]

, 2009
Propagule pressure and disturbance have both been found to facilitate invasion. Therefore, knowledge on the history of introduction and disturbance is vital for understanding an invasion process, and research should focus on areas in which the invasive ...

Role of plant functional traits in determining vegetation composition of abandoned grazing land in north-eastern Victoria, Australia [PDF]

, 2008
Question: In the Northern Hemisphere, species with dispersal limitations are typically absent from secondary forests. In Australia, little is known about dispersal mechanisms and other traits that drive species composition within post-agricultural ...
