The proportion of ducks shot and retrieved while spinning-wing decoys were in use increased with a species' average annual survival rate for adult female dabbling ducks. Supplementary data and related theory indicated that 1 interspecific interfertility is a poor indicator of relationship, 2 the phylogenetic species concept provided the most practical definition of terminal taxa, 3 a majority of groups within the Anatini originated in the southern hemisphere, 4 body size, sexual size dimorphism, and egg size are strongly constrained phylogenetically, whereas sexual dichromatism and clutch size are less predictable, 5 biparental attendance of broods is primitive within Anatini, and 6 characters of definitive plumages, natal plumages, tracheae, and skeletons had similar consistencies but attained maximal utility at different levels within the phylogeny, which indicates different rates of character evolution within the tribe. We then pooled all data from each study site to calculate. BWTE Vrtiska, Nebraska Game and Parks. Our results indicate that the.

Retrieved July 9, This research doesn't cite any other publications. Our final model indicated that main effects describing age, hunting pressure, hunting method, season, relative harvest date, and selected interactions were influential in predicting mass of drake mallards during fall.
