High rates of nutrient loading from agricultural and urban development have resulted in surface water eutrophication and groundwater contamination in regions of Ontario. In Lake Simcoe (Ontario, Canada), anthropogenic nutrient contributions have contributed to increased algal growth, low hypolimnetic oxygen concentrations, and impaired fish reproduction. An ambitious programme has been initiate...

Local ecological knowledge can provide a unique source of data for conservation, especially in efforts to investigate the status of rare or possibly extinct species, but it is unlikely to remain constant over time. Loss of perspective about past ecological conditions caused by lack of communication between generations may create “shifting baseline syndrome,” in which younger generations are les...

Intersex (specifically, testicular oocytes) has been observed in male smallmouth bass (SMB; Micropterus dolomieu) and other centrarchids in the South Branch of the Potomac River, U.S.A., and forks of the Shenandoah River, U.S.A., during the past five years. This condition often is associated with exposure to estrogenic endocrine-disrupting chemicals in some fish species, but such chemicals and ...

On July 4, 2020, heavy rainfall was observed in the southern part of Kumamoto Prefecture and northern Kagoshima Prefecture. Due to rainfall, floods sediment disasters such as collapses debris flows occurred predominantly Kuma River basin We conducted field investigations at four sites Ashikita Town Tsunagi Town, Prefecture, where caused deaths. also Kawauchi branch River, vast amounts discharge...

I. INTRODUCTION We humans tend to worry first about our own happiness, then about our families, then about our communities. In times of great stress, such as war or natural disaster, we may focus temporarily on our country but we rarely think about Earth as a whole or the human species as a whole. This narrow perspective, perhaps best exemplified by the American consumer, has led to the environ...

We present a novel synthesis method for procedural generation of complex curves. Our approach takes a simple example input curve specified by a user and automatically generates complex curves that resembles the input. The algorithm preserves many of the input shape features such as tangent directions, curvature and branch nodes. The overall system is simple and can be used to generate different...
