ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.

ABSTRACT Studying goose domestication through archaeological finds has been challenging due to the similar skeletal morphology of the European domestic goose and its wild progenitor, the greylag goose (Anser anser). We analyzed stable carbon (δ13C) and nitrogen (δ15N) isotopes from bone collagen of subfossil domestic and potentially domestic geese to ...

Acipenseridae is a valuable taxonomic family, both ecologically and economically. They are ideal for morphological analysis in part because the family has existed for at least 70 million years, yet has remained largely anatomically static.

A new well-preserved sturgeon (Chondrostei: Acipenseridae) from the Late Cretaceous of Alberta, Canada [PDF]
In June 2016, the remains of an articulated fish was discovered during field work in Dinosaur Provincial Park, in southern Alberta, Canada. Articulated remains of fishes are very rare in the park, so this specimen was carefully collected and prepared ...

Abstract Information on river velocities enhances understanding flood hazards, evaluating habitat conditions, and predicting the transport of floating materials. In this follow‐up study, we used data from two new sites, one with a more complex morphology and the other with a lower suspended sediment concentration, to provide further evidence that ...

Sturgeon fishing in the Middle and Lower Danube region [PDF]
Migrating sturgeons were the largest fish in the middle and lower Danube region. Most of these species, however, have been brought to the brink of extinction by habitat loss and overfishing. This review is a synthesis of sporadic archaeological evidence,
