MS Project was designed and optimized specifically for the Windows operating system. Building project management software for Macs wasn’t Microsoft’s concern. In fact, the last time that there was a version of Microsoft Project for Apple users was back in 1993 with Microsoft Project 4.0 for Mac.

Abstract

Seabirds are a highly endangered group of vertebrates; they are more threatened than any other group of bird. However, the Common Murre is one species that is showing an increasing population trend; I found that Common Murres have shown a significant increase in δ¹⁵N since 1994, in contrast to the threatened Marbled Murrelet, which has a similar biology but has shown decreasing δ¹⁵ N values that typically correlate with declining population size. This is potentially due to sexual dimorphism that allows for the Common Murre to fill a larger niche. While I found no statistical difference between male and female isotope values, further evaluation could be used to see if this larger niche is a result of other factors. Stable isotope analysis of δ¹³C and δ¹⁵N is one way to investigate these population trends since they are capable of showing foraging habit (inshore vs. offshore) along with trophic level. Unfortunately, as of now, there is no standardized way to sample feathers for isotope analysis, and it has been shown that different locations on the feather show different isotope values which correlate with the melanin concentration of the location. I found a consistent offset in δ¹³C between the tip and base of the feathers sampled. This offset could lead to slight differences in interpretation of the foraging strategy being used by the bird. Since seabirds are in such a threatened position, it is important to have a paramount understanding of their habits possible to ensure the best conservation efforts are being utilized.

Abstract

The Florida Manatee (Trichechus manatus latirostris) is a threatened species that primarily feeds on marine and estuarine seagrasses. Over the past several years, the seagrass coverage in the Indian River Lagoon has varied due to human influence and algal blooms. This led to an unusual number of manatees dying and potentially, to remaining manatees shifting their diets. It can be difficult to decipher why or how diets shift, however, creating a timeline using stable isotopes can help address this challenge. Red blood cells from live Florida Manatees were analyzed for stable carbon, nitrogen, and sulfur isotope ratios. All samples were collected during the winter months of 2011-2015. These samples were analyzed with the goal of examining relationships between the isotope ratios (diet) of the manatees, seagrass coverage, and BCI% over time. All three isotopes were significantly correlated with one another. There was also a clear relationship between the seagrass coverage and isotope ratios each year. It is possible that the density of epiphytes on the seagrass plays a role in manatee health because BCI% was at a high when manatees were primarily feeding on seagrasses, but generally low when seagrass coverage and presumably, seagrass epiphyte density increased. The data from this project increase our understanding of the complex diet-isotope relationship in manatees.
