Evaluating Human Pressure On Protected Areas In East Africa, Bailey M. Ytterdahl Apr 2022

Evaluating Human Pressure On Protected Areas In East Africa, Bailey M. Ytterdahl

Student Publications

Protected areas (PAs) are crucial to achieving effective conservation goals and mitigate the loss of biodiversity. I investigated the following research questions: How does human pressure threaten PAs in East Africa? Is human pressure associated with the factors of country, ecosystem characteristics, size, or governance type of a PA? For this study, I used a combination of a GIS analysis and case studies to evaluate human pressure on PAs in Tanzania and Kenya. For the GIS analysis, I used 589 terrestrial PAs from the World Database on Protected Areas (WDPA). Within each PA, I summarized the landform, landcover, moisture level, …


Ecosystem Service Trade-Offs In Coral Reefs: A Global Analysis, Megan E. Keene Apr 2022

Ecosystem Service Trade-Offs In Coral Reefs: A Global Analysis, Megan E. Keene

Student Publications

Coral reefs are biodiversity hotspots that provide humans with extractive ecosystem services like fisheries and non-extractive services like tourism. Though no studies have examined these trade-offs among these services at a global scale, there are now large, open datasets that make this possible. Using these datasets, we asked whether spatial protection and the level of protection (World Database on Protected Areas) impacted coral reef tourism value (Atlas of Ocean Wealth). We also examined whether proximity to regions of high fishing effort, defined as the top 25th percentile of the average annual effort from Global Fishing Watch, impacted tourism values. Since …


North American Breeding Bird Survey Underestimates Regional Bird Richness Compared To Breeding Bird Atlases, Roi Ankori-Karlinsky, Michael Kalyuzhny, Katherine F. Barnes, Andrew M. Wilson, Curtis Flather, Rosalind Renfrew, Joan Walsh, Edna Guk, Ronen Kadmon Feb 2022

North American Breeding Bird Survey Underestimates Regional Bird Richness Compared To Breeding Bird Atlases, Roi Ankori-Karlinsky, Michael Kalyuzhny, Katherine F. Barnes, Andrew M. Wilson, Curtis Flather, Rosalind Renfrew, Joan Walsh, Edna Guk, Ronen Kadmon

Standardized data on large-scale and long-term patterns of species richness are critical for understanding the consequences of natural and anthropogenic changes in the environment. The North American Breeding Bird Survey (BBS) is one of the largest and most widely used sources of such data, but so far, little is known about the degree to which BBS data provide accurate estimates of regional richness. Here, we test this question by comparing estimates of regional richness based on BBS data with spatially and temporally matched estimates based on state Breeding Bird Atlases (BBA). We expected that estimates based on BBA data would …
