Northern cod (Gadus morhua) movement: insights from acoustic telemetry and genomics

Journal of Fish Biology, EarlyView.
Abstract Knowledge of the timing and diversity of fish movements within a commercially exploited stock complex is required to ensure the sustainability of fisheries. Although migration can be driven by environmental factors, genomic mechanisms also play an important role in this complex life‐history trait. The northern cod (Gadus morhua) stock complex,

Relationship between the environment and the occurrence of invasive pumpkinseed Lepomis gibbosus in lotic and lentic habitats

Journal of Fish Biology, EarlyView.
Abstract The pumpkinseed Lepomis gibbosus is a freshwater fish species native to North America. It has been introduced to Europe, where it is recognized as one of the worst aquatic invaders due to its high adaptability and invasive potential. This study aimed to determine the presence of L. gibbosus in small to medium‐sized water bodies, both lotic and

Governing Transnational Commons: How International Treaties and Multi‐Stakeholder Organizations Shape Cooperation and Conflict

Journal of Management Studies, EarlyView.
Abstract When common‐pool resources such as freshwater, clean air, and fisheries span national borders, the collective action problems encountered are particularly severe. This study explores the role of polycentric governance systems in overcoming these pressing problems, which frequently underlie global grand challenges. Integrating political economy

Maximal Swimming Speed Explains Differences in Habitat Use Among Invasive Ponto‐Caspian Dikerogammarus Species (Crustacea, Amphipoda)

Journal of Zoology, EarlyView.
The three invasive Ponto‐Caspian Dikerogammarus species (D. bispinosus, D. haemobaphes, and D. villosus) show niche differentiation along the current velocity gradient. In the present study, we experimentally measured their maximal swimming speeds to test whether they coincide with their tolerances for currents.

Abstract Hegel displays consistent interest in Judaism, but his presentation seems to differ widely between his earlier and later writings. Contemporary scholarly interpretations of this apparent change also differ widely. In this article, I present the interpretive problem as one of continuity‐discontinuity, and place the major scholarly treatments ...

Theodor Steinbüchel's Great Figures of Christian Humanism

Modern Theology, EarlyView.
Abstract Theodor Steinbüchel (1888–1949) offers a study of eight figures in Western history who may be regarded as gestalts of Christian Humanism. He argued that none of these eight figures will ever return in the same way, but since there was an eternal conception of Christianity to which their ethos gave human form, each of these gestalts can be ...
