Birds choose long-term partners years before breeding
Claire S. Teitelbaum, Sarah J. Converse, Thomas Mueller
2017, Animal Behaviour (134) 147-154
Pair bonds can provide social benefits to long-term monogamous species alongside their benefits for reproduction. However, little is known about when these bonds form, in particular how long they are present before breeding. Previous studies of pair formation in long-term monogamous birds have been rather data-limited, but for many migratory...

Do observed levels of exploitation from consumption-oriented and trophy-oriented fisheries reduce relative stock densities of Muskellunge below target levels in northern Wisconsin?
Matthew D. Faust, Michael J. Hansen
2017, Book chapter, Muskellunge management: Fifty years of cooperation among anglers, scientists, and fisheries biologists
Muskellunge anglers desire to catch large fish, and release rates by recreational anglers often approach 100% (Isermann et al. 2011). Muskellunge are also a culturally significant fish for Chippewa tribes and support a subsistence spearing fishery in Wisconsin’s Ceded Territory (Erickson 2007). Although Muskellunge populations within the state’s Ceded Territory...
