"We're All Aging": A Discourse Analysis Of Older Adults Aging Experiences In Humboldt County, Kaitlyn Dawn Boyes

Cal Poly Humboldt theses and projects

Age is a ubiquitous concept. One minute we are counting down the days until our birthday and the next minute we are ignoring the fact our birthdays exist. Society’s aging population is rapidly growing and is expected to double nearly double by 2050, this increase in population has led to a shift in treatment and attitudes towards both those who are aging and aging itself. There is currently a gap in the literature on aging experiences coming from those experiencing it; rather those in medical professions often dictate these experiences. To help fill those gaps this thesis explores how older …

Ectomycorrhizal Fungal Community Assembly On Seedlings Of A Neotropical Monodominant Tree, Carolyn Delevich

Cal Poly Humboldt theses and projects

Formation of ectomycorrhizae may facilitate early seedling survival of ectomycorrhizal tree species due to enhanced nutrient acquisition. This could be especially important in heavily shaded understories of tropical monodominant forests where host plant photosynthetic capacity is limited. Little information is available on ectomycorrhizal (ECM) fungal colonization or community development of monodominant seedling cohorts, which have high survival rates. Following a 2016 mast seeding event, we sequentially measured percent colonization and species composition of ECM fungi on live and recently dead seedlings of the tropical monodominant tree Dicymbe corymbosa. We also compared seedling ECM fungi to those of nearby adult …
