Wrangling distributed computing for high-throughput environmental science: An introduction to HTCondor Wrangling distributed computing for high-throughput environmental science: An introduction to HTCondor
Biologists and environmental scientists now routinely solve computational problems that were unimaginable a generation ago. Examples include processing geospatial data, analyzing -omics data, and running large-scale simulations. Conventional desktop computing cannot handle these tasks when they are large, and high-performance computing is not always available nor the most appropriate...

Effects of leg flags on nest survival of four species of Arctic‐breeding shorebirds Effects of leg flags on nest survival of four species of Arctic‐breeding shorebirds
Marking wild birds is an integral part of many field studies. However, if marks affect the vital rates or behavior of marked individuals, any conclusions reached by a study might be biased relative to the general population. Leg bands have rarely been found to have negative effects on birds and are frequently used to mark individuals. Leg flags, which are larger, heavier, and might...

Life‐history tradeoffs revealed by seasonal declines in reproductive traits of Arctic‐breeding shorebirds Life‐history tradeoffs revealed by seasonal declines in reproductive traits of Arctic‐breeding shorebirds
Seasonal declines in breeding performance are widespread in wild animals, resulting from temporal changes in environmental conditions or from individual variation. Seasonal declines might drive selection for early breeding, with implications for other stages of the annual cycle. Alternatively, selection on the phenology of nonbreeding stages could constrain timing of the breeding season...

Effects of environmental conditions on reproductive effort and nest success of Arctic‐breeding shorebirds Effects of environmental conditions on reproductive effort and nest success of Arctic‐breeding shorebirds
The Arctic is experiencing rapidly warming conditions, increasing predator abundance, and diminishing population cycles of keystone species such as lemmings. However, it is still not known how many Arctic animals will respond to a changing climate with altered trophic interactions. We studied clutch size, incubation duration and nest survival of 17 taxa of Arctic‐breeding shorebirds at...

Environmental and ecological conditions at Arctic breeding sites have limited effects on true survival rates of adult shorebirds Environmental and ecological conditions at Arctic breeding sites have limited effects on true survival rates of adult shorebirds
Many Arctic shorebird populations are declining, and quantifying adult survival and the effects of anthropogenic factors is a crucial step toward a better understanding of population dynamics. We used a recently developed, spatially explicit Cormack–Jolly–Seber model in a Bayesian framework to obtain broad-scale estimates of true annual survival rates for 6 species of shorebirds at 9...

Evaluating gull diets: A comparison of conventional methods and stable isotope analysis Evaluating gull diets: A comparison of conventional methods and stable isotope analysis
Samples such as regurgitated pellets and food remains have traditionally been used in studies of bird diets, but these can produce biased estimates depending on the digestibility of different foods. Stable isotope analysis has been developed as a method for assessing bird diets that is not biased by digestibility. These two methods may provide complementary or conflicting information on...
