Figure 2 in A gall mite, Aceria rhodiolae (Acari: Eriophyidae), altering the phytochemistry of a medicinal plant, Rhodiola rosea (Crassulaceae), in the Canadian Arctic
Figure 2. Aceria rhodiolae habitus. (A) Many (mostly adult) individuals under dissecting scope. (B) Adult female ventrolateral view (scanning electron micrograph) and (C) dorsolateral view (differential interference contrast light microscopy). Scale on (B) also applies to (C). The large size of female in (C) is in part due to some flattening of that specimen during the slide-mounting process. ch, cheliceral stylets; and other notations indicate setae of prodorsal shield and opisthosoma.

Figure 9. Salidroside and rosavins contents in Rhodiola rosea plants that were ungalled (healthy, n = 94) and galled (deformed, n = 60) by Aceria rhodiolae. Error bars on y-axis are standard deviations.
Figure 4 in A gall mite, Aceria rhodiolae (Acari: Eriophyidae), altering the phytochemistry of a medicinal plant, Rhodiola rosea (Crassulaceae), in the Canadian Arctic
Figure 4. Legs of Aceria rhodiolae female (scanning electron micrographs), from Nunavik (Canada). (A) Legs I (left) and II (right); (B) legs I (left) and II (right). Arrows show ridges (r) on tibia I and II, and some of the spinules on the anterior margins of trochanter, femur, genu and tibia.
Atlantic walrus signal latitudinal differences in the long-term decline of sea ice-derived carbon to benthic fauna in the Canadian Arctic
<p>Climate change is altering the biogeochemical and physical characteristics of the Arctic marine environment, which impacts sea ice algal and phytoplankton bloom dynamics and the vertical transport of these carbon sources to benthic communities. Little is known about whether the contribution of sea ice-derived carbon to benthic fauna and nitrogen cycling has changed over multiple decades in concert with receding sea ice. We combined compound-specific stable isotope analysis of amino acids with highly-branched isoprenoid diatom lipid biomarkers using archived (1982-2016) tissue of benthivorous Atlantic walrus to examine temporal trends of sea ice-derived carbon, nitrogen isotope baseline and trophic position of Atlantic walrus at high- and mid-latitudes in the Canadian Arctic. Associated with an 18% sea ice decline in the mid-Arctic, sea ice-derived carbon contribution to Atlantic walrus decreased by 75% suggesting a strong decoupling of sea ice-benthic habitats. In contrast, a nearly exclusive amount of sea ice-derived carbon was maintained in high-Arctic Atlantic walrus (98% in 1996 and 89% in 2006) despite a similar percentage in sea ice reduction. Nitrogen isotope baseline or the trophic position of Atlantic walrus did not change over time at either location. These findings indicate spatial differences in the restructuring of carbon energy sources utilized by Atlantic walrus and their benthic prey and in turn, a change in Arctic marine ecosystem functioning between sea ice-pelagic-benthic habitats.</p>
