Investigating The Impact Of Land Use On Avian Diversity And Abundance In Areas Surrounding Mabamba Swamp, Uganda, Sydney Marie Jones Oct 2021

Investigating The Impact Of Land Use On Avian Diversity And Abundance In Areas Surrounding Mabamba Swamp, Uganda, Sydney Marie Jones

Independent Study Project (ISP) Collection

The primary objective of this study was to investigate the impact of wetland-adjacent land use on avian species richness and abundance areas surrounding Mabamba Swamp, Uganda. Four types of land use were investigated: Eucalyptus plantations, wetland-edge agricultural fields, residential areas, and mature secondary forests. A total of 40-morning point counts were conducted for ten days in late November and late December of 2021. One-way ANOVA tests and Tukey’s HSD tests revealed significant differences in mean avian richness and abundance between all sites except residential areas and Nkima Forest. Additionally, Nkima Forest was found to contain the most number of specialist …


How Weeds Affect Insects In Mango Cultivation Of South Florida, Blaire Kleiman Jul 2021

How Weeds Affect Insects In Mango Cultivation Of South Florida, Blaire Kleiman

FIU Electronic Theses and Dissertations

The use of weeds as insectary plants is an emerging management tactic by agroecologists and entomologists to sustain beneficial insect species. Fallow lands have always been used by insects and are an important part of their diet in fragmented ecosystems. Weeds provide floral resources to beneficial insects such as pollinators, parasitoids, and predators and resources to keep them within a field in between crop flowering. Using weeds as a tool in tropical fruit production reliant on pollination like Mango (Mangifera indica) allows farmers to reduce herbicide use, increases the biodiversity of both plants and insects, and increases pollination of crops …

Illustration Course Work & Materials

"These essays were were written and illustrated by students at the Rhode Island school of Design in February, 2021. Their perspectives are entirely personal and reflect their efforts within a 5.5-week fused studio/seminar course that was centered on the Sixth Mass Extinction and how biodiversity is changing because of humans. Discovering that science communication is more than delivering just the facts, students were invited to research a topic of personal interest that is relevant to human impacts on biodiversity. Through analysis of data and other scientific information, each sought to synthesize their research and opinions on their topic through a …

Many species of migratory birds are declining worldwide, including throughout North America. Some of the most cited causes of decline are linked to climate change, urbanization, and growth in agriculture. Across eastern Canada, a number of insecticides and herbicides are commonly sprayed before and during the grain growing season to control pests and foliage competitors. During wintering and migration, a declining Arctic-breeding songbird, the snow bunting (Plectrophenax nivalis), utilizes open farmlands of southern Canada; therefore, this could be a period when the species is most exposed to these pesticides. We tested snow bunting tissues (blood and liver) for the 4 …
