Asian Carp: Key To Identification, University of Nebraska - Lincoln

Asian Carp: Key To Identification

National Invasive Species Council

Asian carp are large 39-40 in. (40-50 lb.) fish introduced into the U.S. by fish farmers in Southern states in the 1960’s and 70’s to control vegetation and algae blooms. Three of these species, the grass carp (Ctenopharyngodon idella), bighead carp (Hypophthalmichthys nobilis), and silver carp (Hypophthalmichthys molitrix) have been released or have escaped to the wild and are reproducing in many rivers and streams of the Mississippi River Basin. As they continue to expand their range, and show up in commercial and sport fish catches, a need has arisen to develop a simple …

Weed Control Methods Handbook: Tools & Techniques For Use In Natural Areas, Mandy Tu, Callie Hurd, John M. Randall, The Nature Conservancy

All U.S. Government Documents (Utah Regional Depository)

Invasive non-native plants are a serious threat to native species, communities, and ecosystems in many areas around the world. They can compete with and displace native plants, animals, and other organisms that depend on them, alter ecosystem functions and cycles significantly, hybridize with native species, and promote other invaders. The good news is that many plant invasions can be reversed, halted or slowed, and in certain situations, even badly infested areas can be restored to healthy systems dominated by native species. In most instances this requires taking action to control and manage those invasive plants. This handbook provides you with …

European Starlings: A Review Of An Invasive Species With Far-Reaching Impacts, George M. Linz, H. Jeffrey Homan, Shannon M. Gaulker, Linda B. Penry, William J. Bleier United States Department of Agriculture, Wildlife Services, National Wildlife Research Center, Great Plains Field Station, Bismarck, North Dakota

European Starlings: A Review Of An Invasive Species With Far-Reaching Impacts, George M. Linz, H. Jeffrey Homan, Shannon M. Gaulker, Linda B. Penry, William J. Bleier

Managing Vertebrate Invasive Species

The introduction of European starlings (Sturnus vulgaris) in New York City in 1890 and 1891 resulted in their permanent establishment in North America. The successful occupation of North America (and most other continents as well) has earned the starling a nomination in the Top 100 list of ‘Worlds Worst’ invaders. Pimentel et al. (2000) estimated that starling damage to agriculture crops in the United States was $800 million yearly, based on $5/ha damage. Starlings may spread infectious diseases that sicken humans and livestock, costing nearly $800 million in health treatment costs. Lastly, starlings perhaps have contributed to the …

Fisheries Research Report No. 130 - Environmental Requirements And Tolerances Of Rainbow Trout (Oncorhynchus Mykiss) And Brown Trout (Salmo Trutta) With Special Reference To Western Australia: A Review, Brett W. Molony Department of Fisheries, WA

Fisheries Research Report No. 130 - Environmental Requirements And Tolerances Of Rainbow Trout (Oncorhynchus Mykiss) And Brown Trout (Salmo Trutta) With Special Reference To Western Australia: A Review, Brett W. Molony

Fisheries Research Reports

Both Oncorhynchus mykiss (rainbow trout) and Salmo trutta (brown trout) have a long history of translocation and culture and a wide knowledge base exists. O.mykiss is being considered as a candidate for inland aquaculture in the salinity affected areas of southern Western Australia and this review aims, in part, at providing relevant information to those considering a trout-framing venture in Western Australia. Both species of trout can survive a wide range of environmental conditions, including temperature, salinity, pH, dissolved oxygen and ammonia, with O.mykiss having a higher temperature tolerance than S.trutta. However, within the ranges of environmental conditions, each species …

School of Earth, Environmental, & Marine Sciences Faculty Publications

Long-term assessments of fine particulate matter play a key role in identifying persistent and emerging emission contributors. Coastal urban areas are highly susceptible to transboundary dust and wildfire events in addition to local pollution sources. Multi-decadal assessments in these regions using chemical speciation data could offer insights into major pollutant sources and their trends. This study utilizes nearly two decades of PM2.5 elemental composition data at two major coastal cities in Texas: Houston and Corpus Christi. Fourteen trace elements were analyzed to characterize the seasonal variability and long-term source evolution using a combination of Spearman’s correlation analysis, principal component analysis, …
