Large-scale multi-trophic co-response models and environmental control of pelagic food webs in Québec lakes

Zofia Taranu, Bernadette Pinel-Alloul & Pierre Legendre
Environmental heterogeneity plays a fundamental role in driving species distributions by, for one, fostering niche dimensionality. Within lake ecosystems, species distributions and concordance patterns are driven by both local and regional heterogeneity, though their relative importance across trophic levels has rarely been explored. We developed a statistical framework to compare responses of taxa from different trophic levels to abiotic factors and determine how thisaffected multi-trophic network structures.In particular, we used multi-species concordance modelling (Concordance Analysis...

Prey selection of polar bears in Foxe Basin, Nunavut, Canada: evidence of dietary flexibility in a specialized predator

Melissa P. Galicia, Gregory W. Thiemann, Markus G. Dyck, Steven H. Ferguson & Ian Stirling
Ecological flexibility of a species reflects its ability to cope with environmental change. Although polar bears (Ursus maritimus) are experiencing changes in foraging opportunities due to sea ice loss, regional prey availability and environmental conditions will influence the rate and severity of these effects. We examined changes in polar bear diet and the influence of sea ice characteristics in Foxe Basin over an 18-year period. We combined previous fatty acid data from bears harvested from...

Data from: Wintering bird communities are tracking climate change faster than breeding communities

Smith, Tibor Szep & Chris Van Turnhout
1. Global climate change is driving species’ distributions towards the poles and mountain tops during both non-breeding and breeding seasons, leading to changes in the composition of natural communities. However, the degree of season differences in climate-driven community shifts has not been thoroughly investigated at large spatial scales. 2. We compared the rates of change in the community composition during both winter (non-breeding season) and summer (breeding) and their relation to temperature changes. 3. Based...

Development of a tiered analytical method for forensic investigation of mixed lubricating oil samples

Candice C. Chua, Honoria Kwok, Jeffrey Yan, Daniel Cuthbertson, Graham van Aggelen, Pamela Brunswick & Dayue Shang
Oil spill forensic investigations are often challenging due to many confounding variables such as sample weathering, oil composition complexities, and the quality or quantity of collected materials, but the difficulty is further compounded when dealing with mixed oils. In this case, well-established oil fingerprinting techniques become inadequate, including gas chromatography-flame ionization detection (GC/FID) and gas chromatography-mass spectrometry (GC/MS) diagnostic ratio analysis. In dealing with mixtures of highly refined lubricating (lube) oils, GC/FID analysis often yields...

Experimental variation in the spatial deposition of trace metals in feathers revealed using synchrotron x-ray fluorescence

Fardausi Akhter, Graham Fairhurst, Peter Blanchard, Karen Machin, Rob Blyth, Julie Thompson, Jamille McLeod, Renfei Feng & Catherine Soos
Feathers can be used to investigate exposure to pollution in birds because they are a secondary route for the excretion of trace elements. Evidence based on analytical imaging and spectroscopy suggests that the spatial distribution of the essential trace element zinc within feathers is related to melanin pigmentation. However, our understanding of how trace elements are deposited into growing feathers is poor and has been hampered by a lack of analytical tools to examine the...

Combining point counts and autonomous recording units improves avian survey efficacy across elevational gradients on two continents

Anna Drake, Devin R. De Zwaan, Tomás A. Altamirano, Scott Wilson, Kristina Hick, Camila Bravo, José Tomás Ibarra & Kathy Martin
Accurate biodiversity and population monitoring is a requirement for effective conservation decision-making. Survey method bias is therefore a concern, particularly when research programs face logistical and cost limitations. We employed point counts (PCs) and autonomous recording units (ARUs) to survey avian biodiversity within comparable, high elevation, temperate mountain habitats at opposite ends of the Americas: 9 mountains in British Columbia (BC), Canada and 10 in southern Chile. We compared detected species richness against multi-year species...
