 | Houghton Lake is the largest inland water body in Michigan, covering a surface area of nearly 9,000 ha (22,000 acres). The lake is a major natural and recreational resource for the region with activities including sport fishing, boating, snowmobiling, and habitat for migratory water birds. Problems resulting from the proliferation of the submersed invasive plant, Eurasian watermilfoil, in Houghton Lake led to the development and implementation of a plan for ... |

| Aquatic plants are important to lake ecosystems. The introduction of nonnative plants into littoral zone habitats often alters the complex interactions occurring in these areas. Dense stands of non-native plants are often responsible for reduction in oxygen exchange, depletion of dissolved oxygen, increases in water temperatures, and internal nutrient loading. Eurasian watermilfoil (Myriophyllum spicatum L.) is a non-native invasive species that, when present, has been associated with declines in native ... |

|
| This technical note describes the results of a laboratory investigation conducted to evaluate how fungal endophytes may contribute to plant senescence. This has important implications for aquatic plant control because endophytes turned latent pathogens can induce rapid declines in plant populations. Endophytes are microorganisms that live asymptomatically within host tissues. They are broadly defined as organisms that colonize plant tissues at some time in their life without causing harm to ... |

Angela G Poovey; Michael D Netherland; Wendy Crowell; ENGINEER RESEARCH AND DEVELOPMENT CENTER VICKSBURG MS ENVIRONMENTAL LAB
|
| This study was a first step in documenting inorganic turbidity impacts on fluridone efficacy when controlling the invasive species curlyleaf pondweed. Turbidity in the water column did not substantially impact aqueous fluridone residues. Without turbidity, fluridone concentrations of 3 to 5 micrograms ai/L for a 56-day exposure period suppressed growth of curlyleaf pondweed by 42 to 72 percent, but only slightly reduced turion production. The addition of turbidity to the ... |

|
| Our long-term goal is to understand the ecology of phytoplankton inhabiting coastal shelves, upwelling areas, fjords and banks. We are especially interested in ways in which species-specific properties, including colony size and shape (diatoms) and motility (dinoflagellates) interact with physical mixing processes to regulate spatio-temporal distribution patterns. We wish to understand these processes in sufficient detail to be able to predict bloom dynamics, size structure, and the impact of species-specific ... |

| Thin plankton layers are patches of phytoplankton and/or zooplankton that range in thickness from a few centimeters to a few meters yet can extend horizontally for kilometers and persist for days. Recent work has shown that thin layers can be sufficiently intense and persistent to affect the performance of current and planned Navy optical and acoustical sensors. In Hanson and Donaghay (1998) we showed how thin plankton layers are often ... |

| The rate of invasive species introductions into the United States has steadily increased over the past 20 years. Coupled with ever-increasing human activity has been a steady increase in movement of invasive species resulting in many introductions of species into new landscapes (National Invasive Species Council (NISC) 2001). These introductions can pose serious threats to U.S. Army Corps of Engineers (USACE) installations and projects and their impact is only expected ... |

| Daily high-resolution Sea-viewing Wide Field-of-view Sensor (SeaWiFS) images of the central North Atlantic Ocean (199-2OO3) show that temporal changes in the absorption coefficient of colored dissolved organic matter (CDOM) or "yellow substance" follow changes in phytoplankton pigment absorption coefficient in time. CDOM peaks (between January and March) and troughs (late summer and fall) followed pigment peaks and troughs by approximately two and four weeks, respectively. This phase shift is additional ... |

| Hydrilla has exhibited extensive range expansion along the Rio Grande since it was first discovered in early 1990 and is now found in areas far removed from the original infestation in Brownsville, TX. Hydrilla, a nonindigenous aquatic plant species, has been implicated in restricted water delivery, inaccurate water accounting, and an overall breakdown of system maintenance. The presence of hydrilla also has had a decided impact on native flora by ... |

Some investigators imply widespread and catastrophic damage to reef organisms from errant ordnance, while others suggest that military zones create a de facto sanctuary from deleterious human activities such as coastal development, deforestation, and overfishing. This study documents the condition of fringing coral reefs in military and non-military areas, using the Puerto ... |

| Control of large expanses of aquatic macrophytes with conventional harvesting or herbicide application techniques is often impractical and/or cost- prohibitive. One alternative control measure for these cases is mechanical shredding of macrophytes without harvesting (i.e., clipping or shredding plants and leaving biomass in the system). In particular, mechanical shredding may be very promising for control of monospecific stands of nonnative macrophytes like the water chestnut (Trapa natans), which has invaded ... |

| Since the impoundment of the Mississippi River in the late 1930's, resource managers have been concerned about a reduction in habitat diversity in the Upper Mississippi River System due to sedimentation. Considerable attention has been focused on the accumulation of sediment and its possible effects on aquatic resources in the Upper Mississippi River (UMR). For example, loss of water depth provides an opportunity for rooted aquatic vegetation to colonize open ... |

| Performance of the specialist herbivore Spodoptera pectinicornis (Hampson) (Lepidoptera: Noctuidae) was studied when fed the floating aquatic plant waterlettuce Pistia stratiotes L. (Araceae). Plants were either collected from six populations in south Florida or from plants grown with low or high fertilizer levels. Consumption of leaves with increasing toughness resulted in increased larval mortality to more than 80 percent; most mortality occurred during the ... |

| U.S. Army Corps of Engineers scientists and researchers from the U.S. Department of Agriculture (USDA) began overseas research in the late 196Os to find biological control agents for use in aquatic plant management. This search for natural plant enemies (insects and fungal pathogens) has led researchers to the native ranges of noxious aquatic plants, located throughout the continents of Africa, Asia, Europe, and Australia. For Corps aquatic plant managers, the ... |

| The aquatic fate of the triethylamine (TEA) salt formulation of triclopyr (3,5,6-trichloro-2-pyridinyloxyacetic acid) was studied in Lake Minnetonka, Minnesota. This study determined dissipation rates of triclopyr and metabolites, TCP (3,5,6-trichloropyridinol) and TMP (3,5,6-trichloro-2- methoxypyridine) in water, sediment, finfish, and shellfish. Two plots containing Eurasian watermilfoil-dominated plant communities were treated at 2.5 mg/L triclopyr. The dye rhodamine was applied with triclopyr to provide water- exchange information during the study. Water and ... |
