Sport fisheries of lakes are embedded in complex system of ecological and social interactions. The multiple drivers that affect lake sport fisheries, along with the complex interactions within lakes, make it difficult to forecast changes in sport fisheries and plan adaptive responses to build resilience of these important resources. Resilience involves managing with an eye toward critical thresholds for behavior of ecosystems. Project researchers are working to develop quantitative tools for assessment of thresholds in sport fisheries that can be used by management agencies to evaluate potential impacts of climate change mediated through species and habitat interactions. Several outputs of the project will be adaptable...

On 6 April 2014, a Differential Optical Absorption Spectroscopy (DOAS) instrument was used to measure the radiance of scattered solar radiation passing through the plume emitted from Mount Pagan volcano, Mariana Islands. Spectra were recorded in the ultraviolet (UV: 240 – 390 nm) wavelength range at 0.6 nm resolution. A scanner was used to scan the spectrometer's viewing direction vertically through the volcanic plume. The scanner was located at 18.1235N, 145.7608E and aimed directly to the north (0 degrees azimuth). It scanned the spectrometer's viewing direction from 1 to 90 degrees elevation in steps of 1 degree. The plume was encountered at about 15 to 20 degrees elevation. The scanner was held at each position...

Abstract (from http://www.tandfonline.com/doi/full/10.1080/03632415.2016.1160894): To identify past successes and future opportunities for improved fisheries management in Wisconsin, we synthesized size-structure information on 19 gamefish species from 1944 to 2012, incorporating data on more than 2 million measured individuals. Since the 1940s, mean and mean maximum sizes of five “gamefish” species (Lake Sturgeon Acipenser fulvescens, Largemouth Bass Micropterus salmoides, Smallmouth Bass M. dolomieu, Northern Pike Esox lucius, and Sauger Sander canadensis) have stayed fairly stable, and one (Muskellunge E. masquinongy) initially dropped and then rebounded—most likely as a product of increased catch-and-release...

Climate change is expected to alter the distributions and community composition of stream fishes in the Great Lakes region in the 21st century, in part as a result of altered hydrological systems (stream temperature, streamflow, and habitat). Resource managers need information and tools to understand where fish species and stream habitats are expected to change under future conditions. Fish sample collections and environmental variables from multiple sources across the United States Great Lakes Basin were integrated and used to develop empirical models to predict fish species occurrence under present-day climate conditions. Random Forests models were used to predict the probability of occurrence of 13 lotic fish...

Largemouth Bass (LMB) Micropterus salmoides is one of the most popular sport fish in the United States and is intensively managed across much of its range. Beginning in 1989, Wisconsin implemented more restrictive harvest regulations for LMB, including greater minimum length limits, reduced bag limits, and a catch-and-release-only season during the spawning period across much of northern Wisconsin. We tested for trends in LMB relative abundance, growth, and angler catch and harvest in relation to LMB management policies from 1990 to 2011. We also tested for potential sport fish community responses to changes in LMB abundances using Walleye (WAE) Sander vitreus as an example. Angler catch rates and electrofishing...
