The Record of the Last Sturgeons Caught in the Po River (North Italy) Tells a Cautionary Tale of Reasons of Their Silent Disappearance

River Research and Applications, EarlyView.
ABSTRACT Three sturgeon species—the common European (A. sturio), beluga (H. huso), and Adriatic sturgeon (A. naccarii)—coexisted in the Po River Basin until the mid‐1970s, representing centuries of bio‐cultural heritage for northern Italy's riverine communities.

A Mark‐Recapture Estimate of the Number of American Eels Arriving at the Lowermost Barrier on the Wolastoq|Saint John River, Canada

River Research and Applications, EarlyView.
ABSTRACT The upstream migration of juvenile American eels (Anguilla rostrata) is frequently obstructed by dams and other in‐stream barriers, leading to habitat loss and fragmentation, factors that are believed to contribute to the species' population decline.

Toward a Lockean Unification of Formal and Traditional Epistemology [PDF]

, 2022
Can there be knowledge and rational belief in the absence of a rational degree of confidence? Yes, and cases of "mistuned knowledge" demonstrate this. In this paper we leverage this normative possibility in support of advancing our understanding of the ...
