Three Visualization Approaches for Communicating and Exploring Passive Integrated Transponder Tag Data

As the number, size, and complexity of ecological data sets have increased, narrative and interactive raw data visualizations have emerged as important tools for exploring and understanding these large data sets. As a demonstration, we developed three visualizations to communicate and explore passive integrated transponder tag data from two long‐term field studies. We created three... Read More

Reclaiming a Space for Diadromous Fish in the Public Psyche and Sense of Place

Diadromous species historically dominated the freshwater fish community in coastal northeastern United States rivers. As these fishes declined in concert with sweeping alterations to the region’s waterscapes, so too did their utility, visibility, and relevance to each passing human generation. Due to their historically iconic status, we used endangered Atlantic Salmon Salmo salar as a springboard in... Read More

Evaluating the Conservation Potential of Tributaries for Native Fishes in the Upper Colorado River Basin

Photo credit: U.S. Geological Survey We explored the conservation potential of tributaries in the upper Colorado River basin by modeling native fish species richness as a function of river discharge, temperature, barrier‐free length, and distance to nearest free‐flowing main‐stem section. We investigated a historic period prior to large‐scale water development and a contemporary period. In... Read More

A Long‐Term Watershed‐Scale Partnership to Restore Bull Trout Across Federal, State, Private, and Historic Tribal Land Near Crater Lake National Park, Oregon

  Photo credit: National Park Service We review a 28‐year project to restore a Bull Trout Salvelinus confluentus population in a small Oregon watershed. Restoration evolved from eradication and exclusion of nonnative fishes within the boundaries of a national park to stream reconstruction and reconnection of a historical stream network across state and private property. Management of... Read More

Social Media May Empower Fisheries Students via Learning Networks

Photo credit: D. J. Orth. Social media has great, unrealized potential to improve student learning and engagement. Whereas some traditional face‐to‐face instruction may encourage “cram, pass, and forget” learning strategies, a holistic approach to student learning requires smart use of social media to facilitate long‐term personal, professional, and scholarly development. In this paper, I advocate... Read More

Genetic Mixture Analysis Supports Recalibration of the Fishery Regulation Assessment Model

Management of the commercially important Washington coastal Chinook Salmon Oncorhynchus tshawytscha troll fishery depends on the Chinook Salmon Fishery Regulation Assessment Model (FRAM). The Chinook Salmon FRAM uses historical and contemporary coded wire tag recoveries to estimate abundance and exploitation rates for particular indicator stocks. Those estimates are used to set limits on overall harvest... Read More

Differences in Mercury Exposure among Wisconsin  Anglers Arising from Fish Consumption Preferences and Advisory Awareness

Fish are frequently contaminated with mercury, raising concerns about the human health consequences of eating fish. We quantified mercury exposure and awareness of health advisories among three major ethnic groups of anglers in Madison, Wisconsin, using surveys of species preferences and consumption rates. African American anglers reported eating double and triple the amount of fish... Read More
