Are Road Crossings Fragmenting Populations of Clinch Dace?
(Humboldt Field Research Institute, 2020-11-16)
Chrosomus sp. cf. saylori (Clinch Dace) is a newly recognized species of minnow with a restricted distribution in southwestern Virginia. We analyzed genetic variation and abundance at paired sites above and below road ...
Ammonia-oxidizing bacteria and archaea within biofilters of a commercial recirculating marine aquaculture system
(2018-02-10)
While biofilters are widely used to metabolize ammonia and other wastes in marine recirculating aquaculture systems, the ammonia-oxidizing bacterial and archaeal communities have not been characterized across a diversity ...
Phylogenetic Assessment of Freshwater Mussels Castalia ambigua and C. inflata at an Ecotone in the Paraguay River Basin, Brazil Shows That Inflated and Compressed Shell Morphotypes Are the Same Species
(MDPI, 2020-12-16)
The phylogeny and taxonomy of freshwater mussels of the genus <i>Castalia</i> in South America is complicated by issues of morphological plasticity and limited molecular genetic data. We present field data on the distributions ...
Genetically-Improved Tilapia Strains in Africa: Potential Benefits and Negative Impacts
(MDPI, 2014-06-10)
Two genetically improved tilapia strains (GIFT and Akosombo) have been created with <i>Oreochromis niloticus</i> (Nile tilapia), which is native to Africa. In particular, GIFT has been shown to be significantly superior ...
A Comparison of Systematic Quadrat and Capture-Mark-Recapture Sampling Designs for Assessing Freshwater Mussel Populations
(MDPI, 2019-08-07)
Our study objective was to compare the relative effectiveness and efficiency of quadrat and capture-mark-recapture (CMR) sampling designs for monitoring mussels. We collected data on a recently reintroduced population of ...
Development of Bt Rice and Bt Maize in China and Their Efficacy in Target Pest Control
(MDPI, 2016-10-18)
Rice and maize are important cereal crops that serve as staple foods, feed, and industrial material in China. Multiple factors constrain the production of both crops, among which insect pests are an important one. Lepidopteran ...
Population Genetic Assessment of Anadromous and Resident Striped Bass (Morone saxatilis) in the Roanoke River System, Eastern United States
(MDPI, 2020-08-07)
Striped bass is the subject of important commercial and sport fisheries in North America. The Roanoke River drainage—especially Smith Mountain Lake, Leesville Lake, and Kerr Reservoir—has popular recreational ...
Effects of Hydraulic Retention Time and Influent Nitrate-N Concentration on Nitrogen Removal and the Microbial Community of an Aerobic Denitrification Reactor Treating Recirculating Marine Aquaculture System Effluent
(MDPI, 2020-02-28)
The effects of hydraulic retention time (HRT) and influent nitrate-N concentration on nitrogen removal and the microbial community composition of an aerobic denitrification reactor treating recirculating marine aquaculture ...
Transcriptomic and Metabolomic Responses of Rice Plants to Cnaphalocrocis medinalis Caterpillar Infestation
(MDPI, 2020-10-15)
Interactions between plants and insect herbivores are important determinants of plant productivity in cultivated and natural agricultural fields. The rice leaf folder (<i>Cnaphalocrocis medinalis</i>) causes tremendous ...
Aquaculture-Mediated Invasion of the Genetically Improved Farmed Tilapia (Gift) into the Lower Volta Basin of Ghana
(MDPI, 2019-10-02)
The need for improved aquaculture productivity has led to widespread pressure to introduce the Genetically Improved Farmed Tilapia (GIFT) strains of Nile tilapia (<i>Oreochromis </i><i>niloticus</i>) into Africa. However, ...
