This study compares percent cover of benthic organisms at the species level at Pearl and Hermes
Atoll (PHA), the largest atoll in the Northwestern Hawaiian Islands, in order to determine 1) the
degree of difference among sites, 2) whether wave exposure zones explain observed patterns in
benthic community structure, and...
This study explored the influence of motivations on the volunteer experience. The relationship among motivations. volunteer satisfaction, acceptance and support of the organizational goals, and outcomes of success in the volunteer role (pattern of participation and ombudsman effectiveness) were explored using Multiple Linear Regression analyses. Motivational Systems Theory (Ford, 1992)...
In cranberry (Vaccinium macrocarpon Aiton) cultivation, farmers typically rent colonies of honey bee (Apis mellifera) for pollination. However, the efficiency of this bee at pollinating cranberries in Oregon, as in other regions, is questionable. Bumble bees (Bombus sp.) are reportedly effective in other regions, but their impact in Oregon is...
Acer is a large and important genus of woody plants most commonly encountered as small to large trees in urban landscapes. Considerable investigation has been devoted to addressing the taxonomy of maples, but little is known about genome sizes across the genus. Relatively more work has been conducted to determine...
Frequent and regular contact will help you develop a positive relationship with your grandchildren. Visits give you a chance to spend time together—with and without your grandchildren’s parents—getting to know each other’s interests and stories. Planning will help you make the most of your visits with your grandchildren.
Grandparents give gifts for many different reasons and in many different ways. Some want to honor special occasions and accomplishments with things of value. Some want to encourage their grandchildren to have fun. Others choose gifts that help grandchildren learn about their family or cultural history. Some are satisfied to...
The thermal conductivity, measured by the 3ω method, of amorphous films of Al₂P₁.₂O₆ (AlPO) deposited on Si substrates by an all-aqueous spin-coating technique is 0.93(3) Wm⁻¹K⁻¹. The thermal conductivity of a degenerately doped n-Si substrate is 85(5) Wm⁻¹K⁻¹ and of a more lightly doped p-Si substrate is 139(7) Wm⁻¹K⁻¹. The...
Dams impound the majority of rivers and provide important societal benefits, especially daily water releases that enable on-peak hydroelectricity generation. Such “hydropeaking” is common worldwide, but its downstream impacts remain unclear. We evaluated the response of aquatic insects, a cornerstone of river food webs, to hydropeaking using a life history–hydrodynamic...
