The Effects of Nutrient Additions on Kokanee in Dworshak Reservoir, Idaho
Fisheries Management and Ecology, EarlyView.ABSTRACT We investigated the effects of whole reservoir nitrogen (N) addition on kokanee growth in Dworshak Reservoir, Idaho. We hypothesized that N addition would improve the growth of kokanee (Oncorhynchus nerka) at a given level of abundance by increasing the availability of Daphnia, an important food source.

Enhancing Recharge in the Edwards Aquifer, Texas: Measures, Outcomes, and Lessons for Karst Aquifers
Groundwater, EarlyView.Abstract Managed aquifer recharge is a widely adopted method that involves storing excess water underground for future use. While managed aquifer recharge has been applied globally to different aquifer types, its use in karst aquifers is less common due to the unique hydrogeological characteristics of these systems, including high permeability ...

Groundwater, EarlyView.Abstract Numerical modeling has been widely used to assess the feasibility of geothermal energy development at sites across the world, but modeling applications simulating the potential impacts on shallow hydrothermal resources and surface water are relatively scarce. In this study, we apply the MODFLOW 6 groundwater energy (GWE) code to simulate fully

Revision of Notropis stramineus (Cope, 1865), descriptions of three new species and comments on the monophyly of Miniellus Jordan, 1882 (Pisces: Cypriniformes: Leuciscidae) [PDF]
Vertebrate ZoologyCombined analyses of molecular and morphological data support a revised classification of Notropis stramineus comprising five distinct evolutionary lineages, two for which names are available, Notropis stramineus (Cope, 1865) and N.

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
