The first table contains mass and morphological measurements of body and bill size. The second table provides lengths of individual primary feathers measured from folded wing photographs using a computer software. These feather lengths are to be used in a size-constrained components analysis to calculate wing shape such as pointedness and convexity.

Highly conserved primers which can differentiate these species of interest were developed for four portions of Elodea mtDNA genes (ITS1-5.8S, atpB-rbcL, and two variations of trnL-trnF). The reference sequences and conserved primer sets to identify species present were developed using publicly available data from NCBI GenBank (https://www.ncbi.nlm.nih.gov/genbank/).

ALMS is a collaborative program in which agencies and other entities conduct standardized surveys of breeding birds and their habitats on the lands they manage and then provide the data to the U.S. Geological Survey Alaska Science Center for analysis and archiving. The ALMS monitoring program comprises a set of survey blocks that have been selected in a stratified-random design primarily across state and Federal natural resource lands in Alaska with...

The spatial coverage includes the Gulf of Alaska, Bering Sea, Aleutian Islands, Chukchi Sea, and Beaufort Sea. Fish species within the database include Pacific sand lance, Pacific capelin, Pacific herring, juvenile walleye pollock and Pacific cod, myctophid, squid, and euphausiid. The data package is comprised of six tables: (1) catch_table includes counts, weight, and individual morphological characteristics (length, sex, age) of the sampled species; (2) event_table includes sampling time, location, and methods; (3) gear_table includes specifics about of the gear...
