A modern earth narrative: What will be the fate of the biosphere? A modern earth narrative: What will be the fate of the biosphere?
The modern Earth Narrative is the scientific description of the natural and human history of the Earth, and it is based on two fundamental concepts: Deep (or Geologic) Time and Biological Evolution. Changes in the Earth's biosphere and geosphere are discussed from the perspective of natural variability and impacts of the rapid increase in the human population. The failure of humans to...

Effect of dietary ingredient substition on dorsal fin erosion of steelhead Effect of dietary ingredient substition on dorsal fin erosion of steelhead
A feeding trial was conducted to determine the effect of supplementing a diet based on hydrolyzed fish meal with either 6% chitin (as ground krill shell), 6% squid meal, or 200 mg carotenoid pigment (canthaxanthin) per kilogram on dorsal fin erosion in juvenile steelhead Oncorhynchus mykiss. Three hundred fry in triplicate tanks were fed one of the four test diets, and 300 fry in a...

Habitats used by shortnose sturgeon two Massachusetts rivers, with notes on estuarine Atlantic sturgeon: A hierarchical approach Habitats used by shortnose sturgeon two Massachusetts rivers, with notes on estuarine Atlantic sturgeon: A hierarchical approach
Biotelemetry of shortnose sturgeon Acipenser brevirostrum and Atlantic sturgeon A. oxyrinchus oxyrinchus was used to study fish uses of habitat in several hierarchical classes in the Connecticut and Merrimack rivers. Hierarchical classes were geomorphological region (straight river run, run with an island, and river curve), river cross section (channel or shoal), and microhabitat (water...

The mountain that moved: geologic wonders of the George Washington and Jefferson National Forests The mountain that moved: geologic wonders of the George Washington and Jefferson National Forests
Prehistoric, giant landslides in Montgomery and Craig Counties, Va., in the Blacksburg/Wythe Ranger Districts of the Jefferson National Forest, are the largest known landslides in eastern North America and are among the largest in the world. One of the landslides is more than 3 miles long! The ancient, giant landslides extend for more than 20 miles along the eastern slope of Sinking...

Ecology of stream fish: Insights gained from an individual-based approach to juvenile Atlantic salmon Ecology of stream fish: Insights gained from an individual-based approach to juvenile Atlantic salmon
Using data from an ongoing study of juvenile Atlantic salmon growth and survival in tributaries of the Connecticut River, USA, we compare standard population-level approaches to those focusing on individuals. We highlight the potential benefits of resampling individually tagged stream fish as compared to standard approaches. Specifically we focus on growth, survival, movements and...

Rapid activation of gill Na+, K+-ATPase the euryhaline teleost Fundulus heteroclitus Rapid activation of gill Na+, K+-ATPase the euryhaline teleost Fundulus heteroclitus
The rapid activation of gill Na+,K+-ATPase was analyzed in the mummichog (Fundulus heteroclitus) and Atlantic salmon (Salmo salar) transferred from low salinity (0.1 ppt) to high salinity (25–35 ppt). In parr and presmolt, Salmo salar gill Na+,K+-ATPase activity started to increase 3 days after transfer. Exposure of Fundulus heteroclitus to 35 ppt seawater (SW) induced a rise in gill Na+...
