Assessing Biodiversity at Eastern Oyster (<i>Crassostrea virginica</i>) Aquaculture and Reef Sites Utilizing Real-Time Monitoring and Environmental DNA in Rehoboth Bay, Delaware, USA. [PDF]
Eastern oysters (Crassostrea virginica) are a keystone species and vital to the commercial shellfish industry, acting as environmental engineers that enhance biodiversity. To study their impact, real‐time monitoring and Environmental DNA analysis were conducted at various sites in Rehoboth Bay, Delaware and 23 species were identified, with Spot ...

Epigenetic Responses to Anthropogenic Versus Natural Sources of Oil Exposure Differ in Wild Arctic Seabird Populations. [PDF]
ABSTRACT Anthropogenic pollution can have detrimental effects on organismal physiology, behavior, and fitness, but the underlying genomic mechanisms mediating these effects are not well understood. Epigenetic regulation, such as DNA methylation, has been proposed as a potential mechanism mediating these effects, but currently, there are few studies in ...

Species‐ and origin‐specific susceptibility to bird predation among juvenile salmonids
Abstract Juvenile salmonids often experience high mortality rates during migration and bird predation is a common source of mortality. Research suggests that hatchery‐reared salmonids are more prone to predation than wild salmonids, and that Atlantic salmon (Salmo salar) experience lower predation than Sea trout (Salmo trutta), yet telemetry studies ...

Abstract Objective Alewife Alosa pseudoharengus and Blueback Herring A. aestivalis, collectively referred to as river herring, are anadromous clupeids inhabiting the North American Atlantic coast. Although the seasonal patterns of their spawning migration are well studied and predictable, the fine‐scale movements are still poorly resolved. Methods This

Abstract The increase in abundance of great cormorants (Phalacrocorax carbo sinensis) over the last decades has caused concern for the sustainability of fish populations. Cormorants are opportunistic piscivorous birds that eat fish from a wide range of species and sizes, in marine, lacustrine and riverine habitats.

Cost of regulations on US catfish farms
Abstract Understanding the economic effects of regulations on US aquaculture farms provides insights into which compliance costs create the greatest compliance burden on farms. This can further guide strategies to improve the efficiency of regulatory frameworks and potentially reduce on‐farm compliance costs while maintaining adequate oversight.

Modeling the Economic Impacts of Double-Crested Cormorant Damage to a Recreational Fishery
The double-crested cormorant (Phalacrocorax auritus) has undergone a significant range expansion in the Great Lakes area of the United States since the 1970s, negatively impacting native fish populations and sport fisheries.

Abstract As the dominant means for control of pest rodent populations globally, anticoagulant rodenticides (ARs), particularly the second‐generation compounds (SGARs), have widely contaminated nontarget organisms. We present data on hepatic residues of ARs in 741 raptorial birds found dead or brought into rehabilitation centers in British Columbia ...

Assessing the validity of the accelerometry technique for estimating the energy expenditure of diving double-crested cormorants Phalacrocorax auritus [PDF]
Over the past few years, acceleration-data loggers have been used to provide calibrated proxies of energy expenditure: The accelerometry technique. Relationships between rate of oxygen consumption and a derivation of acceleration data termed "overall ...
