The status of Earth’s diversity is deteriorating quickly which will continue to impact humans’ way of life, as well as every other living creature, in all regions of the world. However, there are organizations taking action to protect biodiversity on our planet. The Convention on Biological Diversity (CBD) is one of those organizations and includes 196 signatories from around the world who are committed to strategies to preserve their biodiversity (Secretariat). Indeed, 98% of the parties which have participated in the Convention on Biological Diversity (CBD) have created national biodiversity strategies (NBS) and action plans (NBSAPs) (Secretariat). Yet, there are still countries that have yet to partake in these efforts. America continues to hold out against ratifying the CBD and remains the only developed country without a National Biodiversity Strategy. As an NBS for the U.S. is under consideration, my goal is to understand what works from previous plans. In particular, I focus on stakeholder engagement in Conservation Biodiversity Action Plans. Stakeholder engagement is important because, without it, there may be insufficient levels of integration of the action plans, which can lead to the failure of the CBDs conservation efforts. To address this question, I analyze the 193 strategies created for countries across the globe. My review describes the ways that stakeholders are engaged in National Biodiversity Strategies for CBD member countries. All plans mention some form of engagement. The most common types mentioned are ‘Education’, ‘Communication’, and ‘Training’. Examining the plans further reveals that most forms of engagement often are just mentioned and not completed. Close to 58% of the engagement forms are only completed about 50% of the time. Exceptions are surveys, interviews, and workshops, which are each completed in over 70% of plans that mention them. I then use this information to provide practical recommendations for creating an effective NBSAP for the United States.

Increasingly, college courses have transitioned from traditional lecture to student-centered active learning, creating more opportunities for students to interact with each other in class. Recent studies have indicated that these increased interactions in active learning can create situations where students’ identities are more salient, which could result in novel challenges for students with marginalized identities. Christianity has been shown to be a marginalized identity in the context of undergraduate biology courses, but it is unknown whether Christian students experience challenges in their interactions with other students in class. The social psychology framework of concealable stigmatized identity (CSI) was used to explore the experiences of Christian students during peer interactions in undergraduate biology courses. Thirty students were interviewed, and most felt their religious identity was salient during peer interactions in biology. Students also reported that they have more opportunities to reveal their religious identity in courses that incorporate peer discussion than in courses that do not. Students claimed that revealing their religious identity to their peers could be beneficial because they could find other religious students in their courses, grow closer with their peers, and combat stereotypes about religious individuals in science. Though most students anticipated stigma, which caused some students to choose not to reveal their religious identities, comparatively few had experienced stigma during peer interactions in their college biology courses, and even fewer had experienced stigma from peers who knew they were religious. These findings indicate that it be may important to teach students how to be culturally competent to reduce Christian students’ anticipated and experienced stigma in active learning courses.

Theories about the human origin in evolution and religion are fundamentally countering beliefs that are still debated to this day. This study continues to explore this relationship in the college population at a public university with the intention of targeting a diverse religious population. This research hopes to answer the question: does having greater literacy in evolution lead to a noninterventionist perspective on evolution? The prediction is that evidence of increased evolution comprehension will influence students to have a more agnostic, or noninterventionist, view on evolution. An evolution class was given a survey that had two parts broken into demographic and evolution sections with one question that asks about compatibility between evolution and religion. This was given twice in a single semester to track the growth of evolution knowledge and any other differences. There were 265 students in the initial survey, but only 223 responses in the post-survey. The compatibility question had 8 statements that range from creationist to atheistic perspectives and was divided into two sides: interventionist (divine involvement) and noninterventionist (deity may be present but does not intervene). More than 70% of the class had a noninterventionist perspective on evolution despite the Christian categories being the second largest group students identified with after agnostic. The agnostic statement was the top choice followed by the atheistic answer on the noninterventionist side. Lastly, there was some growth of evolution knowledge for each religious category in the evolution section but is not significant for interpretation. Based on the collected data, it is not sufficient to answer the question and requires more data collection via a longitudinal study.

Getting clear about what behavioral scientists mean when they invoke content presupposing concepts, like information, is necessary for understanding how humanity’s own behavioral capacities do or do not relate to those of non-human animals. Yet, producing a general naturalistic definition for representational content has proven notoriously difficult. Some have argued that Claude Shannon’s formal, mathematically defined notion of information is the proper starting point for building a biological theory of content. Others have sought to define content presupposing concepts in terms of the historical selection processes that drive evolution. However, neither approach has produced definitions that capture the way successful researchers in the behavioral sciences use content-presupposing concepts. In this dissertation, I examine an ethological tradition of insect navigation research that has consistently ascribed content to insects. To clarify the meaning of such ascriptions, I analyze the practices scientists use to justify new attributions of content and the way new attributions of content guide scientists’ future research activities. In chapter 1, I examine a series of insect navigation experiments performed in 2006–2007 that led to a novel ascription of content. I argue that researchers ascribe content to insects’ navigation behaviors when those behaviors reliably accomplish a difficult goal-directed function. I also argue that ascriptions of content help researchers achieve their epistemic aims by guiding hypothesis formation and aiding comparative theorizing.
In chapter 2, I trace the history of the experimental strategy analyzed above
back to the work of Karl von Frisch in the early 20th century. I argue that von Frisch has a complicated and understudied relationship to the discipline of ethology. I support that argument by highlighting features of von Frisch’s research that both comported with and differed from the program of classical ethology.
In chapter 3, I examine the cognitive map debate in insects. I argue that the debate stems from competing research groups’ endorsement of different norms for justifying claims about the dynamics of representational contents. I then situate these different norms historically to show how the cognitive map debate is a continuation of longstanding divisions within the history of animal behavior research.

Suicide is one of the leading causes of death worldwide and statistical analysis of suicide by profession reveals that physicians and veterinarians experience abnormally high suicide rates. This paper seeks to provide a comprehensive literature review over what some general theories of suicide are, why these professions exhibit high suicide rates, what assistance is currently being provided, and where do these assistance efforts succeed or fail. Moreover, this paper addresses what advancements may be made within these fields to further combat suicide in physicians and veterinarians. To achieve this, general theories behind suicide, risk factors unique to or heavily prevalent in these professions, and current assistance efforts are read, organized, and summarized.<br/><br/>A summary of these risk factors includes stress and mental health disorders accumulated through school and work, personal and professional isolation, access to lethal substances, suicide contagion, exposure to euthanasia, and the role of perfectionism. There are several assistance efforts in place with the most successful ones being highly personalized, but many are still underutilized. Moreover, the stigma of suicide pervades these professions and is addressed by several researchers as something to combat or prevent. Going forward, it is hopeful that not only will more assistance efforts will be created and provided for physicians and veterinarians suffering from suicidal tendencies, but efforts to reduce the stigma of suicide be implemented and utilized as soon as possible.

This thesis analyzes the implications of climate change for insect-borne diseases in humans, focusing especially on mosquitoes and ticks as the two most common vectors. I first introduce relevant background on climate change, arthropod vectors, and the diseases they carry, and the significance of vector-borne diseases for human health. I report on current knowledge of spatial and temporal trends in most common mosquito and tick-borne diseases in the United States, with a detailed table provided in Appendix A. I then review how climatic variability is anticipated to cause profound changes in vector life cycles. In particular, the rise in global ambient temperatures is likely to be the primary driver of arthropod proliferation, although they are also sensitive to changes in humidity, carbon dioxide levels, and water levels. As regions warm, arthropods will be able to survive where they were not able to previously, potentially infecting more individuals. The incidence of several vector-borne diseases in the United States is predicted to increase in multiple states as climate change progresses. The World Health Organization predicts that in North America, Dengue Hemorrhagic Fever and Lyme disease will become the primary vector-borne diseases that are increasingly common (Githeko, et. al, 2000).

Animal testing is a long-running institution in biomedical research that is seen as a necessary step in the development of new drugs and treatments in the United States. Using animal models that have biological similarities to humans, it is assumed that we can ethically perform basic research that is translatable to human health. However, recent years have seen this assumption challenged by the fact that most preclinical research fails to survive the gauntlet of human trials into a functioning treatment on the market. This has marked ethical implications for both the people that depend on new treatments for their health, and the animals used in the research themselves. The purpose of this thesis is to develop solutions for the problems facing animal testing in the United States. First, I identify the political and economic basis of the modern system of animal testing by examining legislation and the IACUCs that govern animal research to understand why the practice continues to be used despite its low rate of success. I then examine factors such as epigenetics and the laboratory environment to explain reasons why animal research fails to translate to humans. Finally, I cover new in-vitro methods such as organoids and organ-on-a-chip technologies to show the potential that alternatives hold for biomedical research. As a result of this analysis, I propose the further integration of alternatives into our system of animal testing to make up for the translational failures the field currently experiences. I also highlight the importance of having IACUCs balanced between animal researchers and members of the public to improve the welfare of animals used in research and increase the transparency of their work. Including more animals into the Animal Welfare Act is also proposed to better standardize our treatment of them and keep experimental results more consistent.

Humans have evolved in many ways. Just look at how life for mankind has changed over the past few decades. It is amazing how different life can be in just a short amount of time. While it is evident that we have impacts of the environment, it should be just as evident that we impact the animals around us. However, there are a few subtle ways in which we impact the evolution of life. Through man-made structures, human interference, artificial lights at night, and electromagnetic fields we have caused animals and insects to evolve and fit these new environments. While we tail the world around us to convince ourselves, the animals also living in these environments need to adapt to survive. In this essay, I will discuss how the affects mentioned above have cause crows, moths, snails, bobcats, blackbirds, mosquitoes, elephants, diurnal animals, fireflies, dung beetles, birds and bats to evolve. The adaptations these organisms made were caused by the subtle ways in which we have impact the landscapes around us.
