“…Overwintering microhabitats are characterised by temperature-buffering and insulating properties, such as those found beneath thick bark, litter, and snow. If overwintering microhabitats occur within vital tree tissues, occupation of these sites can negatively impact host tree fitness (Rexrode and Baumgras 1984;Ye 1991;Hanavan et al 2012;Kirkendall et al 2015).…”

The alder bark beetle, Alniphagus aspericollis (LeConte), is known to overwinter as larvae and adults in the main stems of red alder, Alnus rubra (Bongard). Observations of adult alder bark beetles in the branch and bud nodes of planted saplings during the winter led to the hypothesis that these microhabitats represent alternative overwintering sites for the beetle in mature trees. To test this hypothesis, we surveyed crown branches at three coastal British Columbia locations, sampling three trees in 2003 and 2004 and three additional trees (nine branches per tree) in 2018–2019. Adult beetles were found overwintering inside sites excavated in the branch and bud nodes throughout the crowns of mature trees. Branch type, defined by growth class, and tree affected the overall distribution and likelihood of overwintering site occupancy among the three trees sampled intensively in 2018–2019, whereas overwintering site age (old versus new (current year)) affected the frequency of site occupancy across all six trees. We suggest that overwintering in tree crowns evolved from late-summer maturation feeding in new shoots and that the majority of beetles abandon terminal shoots as temperatures fall, moving deeper into the crown to overwinter preferentially in older branch tissues that offer greater thermal protection.

“…Ducts that arise in response to injury are termed induced secretory ducts (Evert, ; Fahn, ; Hanavan, Adams, & Allen, ). The synthesis of gums, saps, and resins in secretory ducts may occur in response to plant age, stress, and injuries caused by insects, pathogens, birds and mammals (Christiansen et al, ; Evert, ; Fahn, , ; Hanavan et al, ; Koutsoudaki, Krsek, & Rodger, ; Rajput, Sanghvi, Koyani, & Rao, ). Sap is transported in the plant by the xylem and phloem, and is commonly produced in conifers and some angiosperm (Fahn, ).…”

“…Sap is transported in the plant by the xylem and phloem, and is commonly produced in conifers and some angiosperm (Fahn, ). In contrast, gum is synthesized by secretory cells in ducts similar to resin ducts from conifers (Babu & Shah, ; Fahn, ; Hanavan et al, ). Gum, sap and resins also differ in chemical composition.…”

The bark of Anadenanthera peregrina (L.) Speg and Anadenanthera colubrina (Vell.) Bre-nan were characterized in relation to anatomical and chemical features. The barks were similar and included a thin conducting phloem, a largely dilated and sclerified non-conducting phloem, and a rhyridome with periderms with thin phellem interspersed by cortical tissues. Only small differences between species were observed that cannot be used alone for taxonomic purposes. The summative chemical composition of A. peregrina and A. colubrina was respectively: 8.2% and 7.7% ash; 28.8% and 29.3% extractives; 2.4% and 2.6% suberin; and 18.9% lignin. The monosaccharide composition showed the predominance of glucose (on average 82% of total neutral sugars) and of xylose (9%). The ethanol-water extracts of A. peregrina and A. colubrina barks included a high content of phenolics, respectively: total phenolics 583 and 682 mg GAE/g extract; 148 and 445 mg CE/g extract; tannins 587 and 98 mg CE/g extract. The antioxidant activity was 238 and 269 mg Trolox/g extract. The barks of the Anadenanthera species are a potential source of polar extractives that will represent an important valorization and therefore contribute to improve the overall economic potential and sustainability of A. peregrina and A. colubrina
