How to study plant roots!

This is an interesting article about excavating roots to show their growth. The plants are apples and raspberries. We have done root excavations at Hort UAF, and it is a pain in the backside! This excavation is extraordinary!  Root excavations

Bumble bees are best for haskap pollination

This research showed that bumble bees, Bombus terrestris were the most important pollinators of Lonicera cerulea, honey berry/haskap. Honey bees are good as a supplement but they don’t work in cold temperatures, and their efficiency is far less that the B.B.

Alaska Butterflies

Here is a link to a book just published on all Alaska butterflies. Senior author is the late Ken Philip, an amazing man who loved butterflies and tromping around the state looking for them.  He was a wonderful resource for all things butterflies. His collections now reside at the UAF museum and the Smithsonian.

Alaska-Yukon Circumboreal Region Map

Here is a great document with outstanding photos of a mapping project for the vegetation of the Alaska-Yukon Region by Fairbanks researcher, Torre Jorgensen and others. It is an attempt to refine vegetation classification systems using the latest technology.

Processing and phenolic compounds in honey berry

The aim of the study was to evaluate different methods used for the preparation of powders from blue honeysuckle (Lonicera caerulea L. var. kamtschatica) cv. ‘Wojtek’, and the effects of these methods on chemical composition and antioxidant activity of lyophilized powders and pomace. The analyzed samples were evaluated for their basic chemical composition (dry weight, pH, total acidity, sugars (glucose, fructose and sucrose), and antioxidant capacity (FRAP, ABTS). Polyphenolic compounds were identified and quantified by UPLC-PDA-MS/MS. Thirty eight polyphenolic compounds, including eight phenolic acids, eight anthocyanins, five flavan-3-ols, twelve flavonols and five flavones were identified in blue honeysuckle products. The highest content of bioactive compounds was detected in juice pressed from peels, as compared with fresh berries and other products. Moreover, crushed berries were found to be a better material for obtaining dried product than intact fruit. Jan OszmiańskiAneta Wojdyło, and Sabina Lachowicz. 2015.
