The red tree coral Primnoa pacifica is an important habitat forming octocoral in North Pacific waters. Given the prominence of this species shelf and upper slope areas Gulf Alaska where fishing disturbance can be high, it may able to sustain healthy populations through adaptive reproductive processes. This study was designed test hypothesis, examining mode, seasonality fecundity both undamaged simulated damaged colonies over course 16 months using a deepwater-emerged population Tracy Arm...

Red tree corals (Primnoa pacifica) are abundant in the eastern Gulf of Alaska, from glacial fjords Southeast Alaska where they emerge to as shallow 6 m, continental shelf edge and seamounts more commonly found at depths greater than 150 m. This keystone species forms large thickets, creating habitat for many associated species, including economically valuable fishes crabs, so important benthic suspension feeders this region. Though reproductive periodicity over 1.5 year period was reported...

Abstract In the Gulf of Alaska, commercially harvested fish species utilize habitats dominated by red tree corals ( Primnoa pacifica ) for shelter, feeding, and nurseries, but recent studies hint that environmental conditions may be interrupting reproductive lifecycle corals. The North Pacific has experienced persistent extreme thermal variability in years this pattern is predicted to continue coming decades. Recent discovery deep-water emerged coral populations Southeast Alaska fjords...

We, registered dietitian nutritionists (RDNs), could have sat on the sidelines in early days of pandemic when many RDNs were not considered “essential” workers. Instead, used their abilities to innovate and adapt ensure public, patients, clients received continuous nutrition services. Some strategies adopted possible because temporary or emergency flexibilities policies. We present examples primarily from our outpatient practices, with efforts by public health inpatient acknowledged. hope...
