Article
Full-text available
Local and regional habitat conditions associated with agricultural activity can fundamentally alter aquatic ecosystems. Increased nutrient inputs, channelization and reduced riparian habitat both upstream and locally contribute to the degradation of stream ecosystems and their function. Here, we examine stream food webs in watersheds that feed into...

Full-text available
Recent examples of rapid brain size plasticity in response to novel laboratory environments suggest that fish brain size is a flexible trait, allowing growth or shrinkage of brain tissue based on short term needs. Nevertheless, it remains to be seen if plasticity of fish brain size is relevant to natural environmental conditions. Here, using rainbo...
Article
Full-text available
Building the capacity of efficiently determining the provenance of food products represents a crucial step towards the sustainability of the global food system. Despite species specific empirical examples of multi-tracer approaches to provenance, the precise benefit and efficacy of multi-tracers remains poorly understood. Here we show why, and when...

Full-text available
Globalchange is fundamentally altering flows of natural and anthropogenic subsidies across space 13 and time. After a pointed call for research on subsidies in the 1990s, an industry of empirical work 14 has documented the ubiquitous role subsidies play in ecosystem structure, stability and function. 15 Here, we argue that physical constraints (e.g...

Building the capacity of efficiently determining the provenance of food products represents a crucial step towards the sustainability of the global food system. Whether it is for enforcing existing egislation or providing reliable information to consumers, technologies to verify geographical origin of food are being actively developed. Biological t...
Article
Full-text available
Anthropogenic subsidies occur readily, especially with growing human development neighboring natural systems. Determining how these subsidies permeate into native food webs is important, but currently not well understood. Here, we used a combination of stable isotopes and fatty acids as bio-tracers to explore the pathway(s) of assimilation of an an...
Article
The fragmented ecosystems along the Niagara Escarpment World Biosphere Reserve provide important habitats for biota including lichens. Nonetheless, the Reserve is disturbed by dense human populations and associated air pollution. Here we investigated patterns of lichen diversity within urban and rural sites at three different locations (Niagara, Ha...
Article
10-15% of women take selective serotonin reuptake inhibitor (SSRI) antidepressants during pregnancy. Offspring exposed to SSRIs are more likely to be low birth weight; this is associated with an increased risk of developing diabetes in adulthood in part due to altered pancreatic development. The effects of perinatal exposure to SSRIs on pancreatic...
