Chemical compositions of amphiboles found in veins and hosts rocks of Cretaceous plutons of the Northern Cascades

Creator:

George, Austin

Abstract:

The origin of hornblendite and other mafic mineral-rich veins found in Cretaceous plutonic rocks from the Northern Cascades is currently not well known. This study seeks to investigate the possible relationship between host plutonic rocks and hornblendite and pyroxene-rich veins by comparing the chemical compositions and petrographic features between the...

How sweet is the land? Modeling caloric landscapes for tropical hummingbirds

Creator:

Birkett, Christina Nozomi and Birkett, Nozomi Fukui

Abstract:

Pollination is a critical ecosystem function for sustaining biodiversity. However, pollinators and the services they provide are threatened by landscape-altering anthropogenic activities across the globe. Habitat loss and fragmentation, introduction of invasive species, chemical use, and urbanization have been shown to impact pollination. Pollinator foraging behavior is thought to be...
