The SPLASH project (2004–2006) revealed complex population structure and migratory connections, but no regional effort was made along the southern Mexican Pacific coast until dedicated research was initiated in 2010. It is unclear whether humpback whales documented in this region belong to the Mexican or Central American population units. This study aimed to establish the relationship between humpback whales of southern Mexico...

Mouthrot, or bacterial stomatitis, is a disease which mainly affects farmed Atlantic salmon, ( Salmo salar , L.), smolts recently transferred into salt water in both British Columbia (BC), Canada, and Washington State, USA. It is a significant fish welfare issue which results in economic losses due to mortality and antibiotic treatments. The associated pathogen is Tenacibaculum maritimum , a bacterium which causes significant...

Understanding the evolutionary consequences of the green revolution, particularly in wild populations, is an important frontier in contemporary biology. Because human impacts have occurred at varying magnitudes or time periods depending on the study ecosystem, evolutionary histories may vary considerably among populations. Paleogenetics in conjunction with paleolimnology enable us to associate microevolutionary dynamics with d...

Little is known about the role of transcriptomic changes in driving phenotypic evolution in natural populations, particularly in response to anthropogenic environmental change. Previous analyses of Daphnia genotypes separated by centuries of evolution in a lake using methods in resurrection ecology revealed striking genetic and phenotypic shifts that were highly correlated with anthropogenic environmental change, specifically...

For an accurate assessment of the anthropogenic impacts on evolutionary change in natural populations, we need long‐term environmental, genetic and phenotypic data that predate human disturbances. Analysis of c . 1600 years of history chronicled in the sediments of South Center Lake, Minnesota, USA , revealed major environmental changes beginning c . 120 years ago coinciding with the initiation of industrialised agriculture in...

This study examined the toxicological and physiological responses of a commercially important coral‐reef grouper, Plectropomus leopardus (Serranidae), to injection of enriched stable‐isotope barium chloride (BaCl 2 ) solution. Thirty adult P. leopardus were subject to one of two 138 BaCl 2 injection treatment groups (corresponding to dosage rates of 2 and 4 mg 138 Ba kg −1 body mass), and a control group in which fish were inj...
