Predatory interactions of Gorareduvius with and without resin
<p><em>Gorareduvius</em> sp. (proposed name G. <em>gajarrangarang</em> is under revision) assassin bugs collect a sticky resin from spinifex grass (<em>Triodia</em> spp) in Australia. We evaluated whether this resin conveys a predatory advantage to the assassin bugs, by staging predatory interactions in the field, under controlled conditions. Assassin bugs were sequentially exposed to two types of prey (ants and flies), and while being equipped with or deprived of resin. This was a repeated measures design that controlled for individual predatory ability, in which the order of the trials was randomized. The predatory interactions yielded four different types of data, which were analyzed separately, as detailed below. </p>

Nitrogen Deposition to an Alberta Bog as Measured with Mixed-bed Ion Exchange Resin Tube Collectors, 2011-2015
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). Resin tubes filled with mixed-bed ion exchange resin were swapped in and out at each collection/deployment date (mid-May and mid-October of each year). Upon collection, resins were extracted with 1M KI and analyzed for inorganic N concentrations. Deposition of NH4 +-N, NO3 --N, and DIN averaged 187 ± 11, 237 ± 13, and 426 ± 19 μg m-2 da-1, corresponding to 0.68 ± 0.04, 0.87 ± 0.05, and 1.55 ± 0.07 kg N ha-1 yr-1, with no significant differences between open and throughfall collectors for any of the three measured parameters (p >= 0.63). Deposition of NH4 +-N was significantly higher during the growing season (averaging 240 μg m-2 da-1) than during the winter months (averaging 121 μg m-2 da-1) (p = 0.0004), while NO3 --N and DIN deposition did not differ significantly between winter and summer (p = 0.06 and 0.13, respectively).
Nitrogen Deposition to an Alberta Poor Fen as Measured with Mixed-bed Ion Exchange Resin Tube Collectors, 2011-2015
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. To examine responses to N deposition, over five years, we experimentally applied N (as NH4NO3) to a poor fen near Mariana Lake, Alberta, at rates of 0, 5, 10, 15, 20, and 25 kg N ha-1 yr-1, plus controls (no water or N addition). Resin tubes filled with mixed-bed ion exchange resin were swapped in and out at each collection/deployment date (mid-May and mid-October of each year). Upon collection, resins were extracted with 1M KI and analyzed for inorganic N concentrations. Over all ion exchange resin tube collection dates, deposition of NH4+-N, NO3--N, and dissolved inorganic N (DIN; NH4+-N + NO3--N) averaged 240 ± 29, 318 ± 27, and 557 ± 41 µg m-2 da-1, values that are equivalent to 0.87 ± 0.10, 1.16 ± 0.10, and 2.03 ± 0.15 kg N ha-1 yr-1. While NH4+-N deposition was higher in the growing season than in non-growing season (p = 0.0006), NO3--N deposition was higher in non-growing season than during the growing season (p = 0.0052), with the net result being no seasonal difference in DIN deposition (p = 0.6428).

Apothecary vessel for dragon resin
The presented apothecary vessel with a cylindrical shape was made of wood and covered with black oil paint. The inscription: Sanguis Drac.[onis], literally meaning dragon's blood. In reality, it is a red resin covering the fruits of a rattan palm tree (Daemonorops draco (Willd.) Blume). It is also obtained by cutting the bark and leaves of the dragon tree (Dracaena draco L.). Dragon blood was used as a red pigment to dye other medicinal preparations.
