Reconstructing the natural distribution of individual unionid mussel species and species diversity in wadeable streams of Illinois, USA, with reference to stream bioassessment

Autor: Alison P. Stodola, Kevin S. Cummings, Yong Cao, Ann Marie Holtrop, Leon C. Hinz, Sarah A. Douglass

Publikováno v: Freshwater Science. 36:669-682

Freshwater mussels are considered one of the most imperiled aquatic species groups in the USA. One of the challenges in protecting and restoring mussel biodiversity effectively is a lack of understanding of their natural distributions at relevant spa

Autor: Brian A. Metzke, Ann Marie Holtrop, Yong Cao, Jeffrey A. Stein, Leon C. Hinz

Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 73:1031-1046

To effectively conserve and restore stream ecosystems, we need to better understand the distribution and abundance of individual fish species in relation to natural environments and anthropological stressors. In this study, we modeled the abundance o

Modeling changes in freshwater mussel diversity in an agriculturally dominated landscape

Autor: Jian Huang, Yong Cao, Ann Marie Holtrop, Kevin S. Cummings

Publikováno v: Freshwater Science. 32:1205-1218

Freshwater mussels perform critical ecosystem functions and provide many valuable ecological services. However, anthropogenic effects have severely decreased mussel diversity and abundance at both local and regional scales. Understanding how human di

Evaluating the Illinois Stream Valley Segment Model as an Effective Management Tool

Autor: Ann Marie Holtrop, Leon C. Hinz, James M. Novak, Stephen S. Warrner, Robert U. Fischer

Publikováno v: Environmental Management. 46:761-770

Stream habitat assessments are conducted to evaluate biological potential, determine anthropogenic impacts, and guide restoration projects. Utilizing these procedures, managers must first select a representative stream reach, which is typically selec
