: Smile and a Neutral Attitude; This thesis examines the ways in which body image is discussed in online settings. There are three different communities discussed: body positivity, proED (pro-eating disorder), and body neutrality. Both body positivity and proED content are fairly popular online, and both have found significant support and followers on various social medias. In this thesis, I argue that both of these types of content cause significant harm to those who engage with them, primarily because both communities (though different in their approaches to body image) work to uphold the thin ideal. I then bring up the third type of content: body neutrality. Body neutrality has not been given the same academic attention as body positivity and proED content, likely due to its relative infancy. In this thesis, I propose body neutrality as a much healthier way to frame body image online because of its completely neutral stance on fat, thinness, and general body image. Though any work relating to social media is quickly out of date, I hope that this thesis provides an overview of body neutrality and how, in its current form, it provides a more balanced approach to online body image discussions.

: Intra-seasonal Variation in Black Tern Nest-site Selection and Survival; Resources and risk are in constant flux and an organism’s ability to manage change may improve their likelihood of persistence. I examined intra-seasonal variation in nest-site selection and survival of a declining wetland bird, the Black Tern (Chlidonias niger surinamensis). I modelled nest site occupancy and survival of early and late-nesting birds as a function of static and dynamic factors. Early-nesting birds selected nest sites based on the degree and direction of habitat change that occurred over the nesting cycle, while late-nesting birds selected sites based on static conditions near the time of nest-site selection. Nest age had the strongest influence on daily survival rate for both early and late-nesting birds, but the shape of this relationship showed intra-seasonal differences. Additionally, early-season survival improved slightly with increasing vegetation coverage and distance between conspecific nests, while late-season survival increased with clutch size. My results suggest that intra-seasonal variation in nest-site selection and survival is driven by changing habitat conditions and predator behavior.
