Litter decomposition in running water sometimes proceeds faster in small, cool tributaries than in warm, wide rivers because stenothermal, leaf-shredding invertebrates are more abundant in the cool streams. Evidence from eastern Canada suggests that the cold-stenothermal stonefly Leuctra has a disproportionate influence on rapid mass loss in upstream(More)
Data sets from three laboratories conducting studies of movements and migrations of Atlantic swordfish (Xiphias gladius) using pop-up satellite archival tags were pooled, and processed using a common methodology. From 78 available deployments, 38 were selected for detailed examination based on deployment duration. The points of deployment ranged from(More)
The compiled data for this study represents the first Atlantic and Mediterranean-wide effort to pool all available biometric data for Atlantic bluefin tuna (Thunnus thynnus) with the collaboration of many countries and scientific groups. Biometric relationships were based on an extensive sampling (over 140,000 fish sampled), covering most of the fishing(More)
In shallow, rocky-bottomed river systems in Nova Scotia, Canada, decomposition rates of autumn-fallen red maple (Acer rubrum) and speckled alder (Alnus incana) leaf litter were determined in spring and early summer using litter bags. In most shaded upstream tributaries, decomposition followed a typical exponential curve (k = −0.013 to −0.032 day−1). In(More)
Table 2 was published with an incorrect number of specimens (n) and coefficient of determination (r) for the weight conversion factors RWT-GGWT and GGWT-RWT for the East and Mediterranean stock unit. As the correct r is lower than the high coefficient of determination chosen as threshold for using the biometric relationship (r-square 0.98), we prefer to(More)
