Animals move to locate important resources such as food, water, and mates. Therefore, movement patterns can reflect temporal and spatial availability of resources as well as when, where, and how...
-
These surveys are completely incidental and are conducted as staff at the YBWA conduct regular daily activities. While on the Wildlife Area, staff record each brood of waterfowl or ring-necked...

Background Changes in the survival-rate during the larval phase may strongly influence the recruitment level in marine fish species. During the larval phase different 'critical periods'...
-
Monitoring demographic response over time is valuable for understanding population dynamics of endangered species. We quantified the variation in survival patterns for three small isolated island...
-
A moose population survey was conducted on the Yukon Flats in November 2015. This was the first fall survey since 2010 due to a lack of sufficient snow in early winter that caused surveys in...
-
Measurements of fog, wind, fog interception, soil moisture, and fog effects on plant water use and plant survival were collected along with these vegetation data to test a model to estimate CWI as...

Environmental contamination can negatively impact fish populations. In addition to acute toxicity leading to death, toxicants can reduce fish growth and lower reproduction. The potential for...
