Genomic signatures of extensive inbreeding in Isle Royale wolves, a population on the threshold of extinction

The observation that small isolated populations often suffer reduced fitness from inbreeding depression has guided conservation theory and practice for decades. However, investigating the genome-wide dynamics associated with inbreeding depression in natural populations is only now feasible with relatively inexpensive … read more

Predicting Prey Population Dynamics From Kill Rate, Predation Rate And Predator–Prey Ratios In Three Wolf-ungulate Systems

Predation rate (PR) and kill rate are both fundamental statistics for understanding predation. However, relatively little is known about how these statistics relate to one another and how they relate to prey population dynamics. We assess these relationships across three … read more

Impacts of Breeder Loss on Social Structure, Reproduction, and Population Growth in a Social Canid

The importance of individuals to the dynamics of populations may depend on reproductive status, especially for species with complex social structure. Loss of reproductive individuals in socially complex species could disproportionately affect population dynamics by destabilizing social structure and reducing … read more

Rediscovery of Red Wolf Ghost Alleles in a Canid Population Along the American Gulf Coast

Though red wolves were declared extinct in the wild by 1980, a team of biologists has found their DNA in a group of canines living on Galveston Island off the coast of Texas. DOWNLOAD PDF

Minnesota Wolf Population Update 2017

2016-17 mid-winter Minnesota wolf population estimated at 2,856 wolves, or 4.0 wolves per 100 km2 of occupied range. The 90% confidence interval was approximately +/- 500 wolves, specifically 2,371 to 3,382 and 508 wolf packs. DOWNLOAD

Alaska Confirms 60 Percent Decline in Rare Wolf Population, Still Plans Trapping and Hunting Season

SITKA, Alaska— The Alaska Department of Fish and Game is planning a 2015-2016 trapping and hunting season on rare Alexander Archipelago wolves in the Prince of Wales Island area, despite scientific data confirming a 60 percent decline in the wolf … read more
