Abstract Pollination provided by bees is a critical ecosystem service for agricultural production. However, bee populations are at risk from stressors such as habitat loss, pesticides, and disease. On-farm wildflower plantings one mitigation strategy to provide resources bees. In many instances, government programs can subsidize the installation of these private landowners. Semi-natural (SNH) i...

Listening is a pervasive and significant act of conservation research praxis, mattering greatly for the realisation agendas, not least its ambitions to be outward looking inclusive in approach. Yet, value role listening has been barely explored sustained reflexive way. This paper preliminary schematic what it might mean attend listening, set within context larger field scholarship as well more ...

Whale-watching has the potential for ecotourism due opportunities supporting cetacean research, environmental education, and community engagement. Whalesafari, first whale-watching company in Arcti...

We consider initial-boundary-value problems for systems of conservation laws and design entropy stable finite difference schemes to approximate them. The schemes are shown to be entropy stable for a large class of systems that are equipped with a symmetric splitting, derived from the entropy formulation. Numerical examples for the Euler equations of gas dynamics are presented to illustrate the ...
