Sphagnum fuscum Capitulum Density, Mass, and N Concentrations From N-Addition Plots in an Alberta Peatland, 2013-2015
Development of the oil sands has led to increasing atmospheric N deposition, with values as high as 17 kg N ha-1 yr-1; regional background levels <2 kg N ha-1 yr-1. Bogs, being ombrotrophic, may be especially susceptible to increasing N deposition. To examine responses to N deposition, over five years, we experimentally applied N (as NH4NO3) to a bog near Mariana Lakes, Alberta, at rates of 0, 5, 10, 15, 20, and 25 kg N ha-1 yr-1, plus controls (no water or N addition). From 2013-2015, we examined the effects of N addition on changes in S. fuscum capitulum mass density, N concentrations, and N contents in plants collected in early July (summer) and early October (fall). In each year, capitulum mass density decreased with increasing N input at equal rates in summer-collected and fall-collected plants, although CMD was consistently higher in fall-collected than in summer-collected plants. For both summer- and fall-collected plants, capitulum N concentrations were unaffected by N inputs, although N concentrations were consistently higher in summer (14.4 ± 0.3 mg g-1) than in fall (0.7 ± 0.1 mg g-1). Combining CMD and capitulum N concentrations, capitulum N contents overall averaged 1.16 ± 0.04 g m-2. Capitulum N contents decreased with increasing N input, with the response being stronger in 2013 than in 2014/2015 . These results, combined with stem and capitulum responses at Mariana Lakes Bog, suggest that increasing N loading affects not only S. fuscum NPP, but also the way in which S. fuscum grows.

Seed size and capitulum position drive germination and dormancy responses to projected warming for the threatened dune endemic Cirsium pitcheri (Asteraceae)
<p>Among coastal plant species at risk from rapid environmental changes is the North American Great Lakes dune endemic Cirsium pitcheri. Despite being listed as federally threatened, little is known about how C. pitcheri seed attributes influence germination and dormancy-break patterns in the context of climate change. Following a previous work where we found differences in the number and weight of C. pitcheri seeds among capitulum positions and study sites, here we examine the effects of seed attributes (capitulum position, seed weight and site of origin) on the proportion and timing of C. pitcheri seed germination under temperature treatments that simulate projected warming in the Great Lakes (20/10°C, 25/10°C and 30/10°C day/night). Our results demonstrate that C. pitcheri produces diverse cohorts of seeds with seed attributes that significantly influence the timing and probability of germination over a three-year soil seed bank. C. pitcheri seed germination proportions were highest at 20°C and decreased successively at 25°C and 30°C. Seeds from terminal capitula had higher germination proportions and took longer to germinate than those from secondary capitula. The effect of seed weight on germination probability also depended on site of origin and capitulum position, with all effects varying in size and significance over time. Our results highlight the considerable differences in germination patterns exhibited by seeds from different capitulum positions and sites of origin and provide insight into the dormancy-break patterns that C. pitcheri might experience under the predicted temperature rise in the Great Lakes region of North America.</p>
