Complications of Estimating Hatchery Introgression in the Face of Rapid Divergence: A Case Study in Brook Trout (Salvelinus fontinalis). [PDF]

open access: yesEvol Appl
Fish stocking has been utilized for over a century to offset extirpations or declines in abundance of many native species. These historical declines and hatchery contributions have led to uncertainty surrounding whether many contemporary populations are ...

Infant formula iron fortification of 2 vs. 8 mg/L does not increase the risk of iron deficiency or impact neurodevelopment at 12 months

open access: yesJournal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives The aim of this follow‐up was to investigate how reduced iron concentration and added bovine lactoferrin in infant formula affect neurodevelopment, iron status, and growth at 12 months of age. Methods Swedish healthy term formula‐fed infants (n = 180) were randomly assigned to receive, from 6 weeks to 6 months of age, a low‐iron ...

PNNL‐TUNAMELT: Toward automating the detection of interactions with marine energy devices using acoustic camera sensors

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Acoustic cameras, or imaging sonars, are often used to monitor marine energy sites in regions where the water is too dark or turbid for optical sensing. To do so more effectively, scientists are investigating automated detection methodologies to use on these data.

Large, rugged and remote: The challenge of wolf–livestock coexistence on federal lands in the American West

open access: yesPeople and Nature, EarlyView.
Abstract The expansion of grey wolves (Canis lupus) across the western United States, including on public lands used for extensive livestock grazing, requires tools and techniques for reducing wolf–livestock conflict and supporting coexistence. We examined approaches used on forested lands managed by the U.S.
