As threats to Earth's biodiversity continue to evolve, an effective methodology to predict such threats is crucial to ensure the survival of living species. Organizations like the International Union for Conservation of Nature (IUCN) monitor the Earth's environmental networks to preserve the sanctity of terrestrial and marine life. The IUCN Red List of Threatened Species informs the conservation activities of governments as a world standard of species' risks of extinction. However, the IUCN's current methodology is, in some ways, inefficient given the immense volume of Earth's species and the laboriousness of its species' risk classification process. IUCN assessors can take years to classify a species' extinction risk, even as that species continues to decline. Therefore, to supplement the IUCN's classification process and thus bolster conservationist efforts for threatened species, a Random Forest model was constructed, trained on a group of fish species previously classified by the IUCN Red List. This Random Forest model both validates the IUCN Red List's classification method and offers a highly efficient, supplemental classification method for species' extinction risk. In addition, this Random Forest model is applicable to species with deficient data, which the IUCN Red List is otherwise unable to classify, thus engendering conservationist efforts for previously obscure species. Although this Random Forest model is built specifically for the trained fish species (Sparidae), the methodology can and should be extended to additional species.

There is no possibility for an ecological crisis without someone to be in crisis. The environment is not in danger as such, humanity’s ability to persist in it with well-being is. Thus, the ecological crisis is a human crisis, a crisis of meaning. Although ecology is required to understand and address these problems, we must understand the human condition if we wish to address them with any amount of seriousness or hope for success. We will be concerned with the relevance of hermeneutic practices in the study and practice of ecology. By hermeneutic practices, I mean the practices central to the human condition of world-building through perpetual interpretation and re-interpretation informed by one’s facticity. By the study and practice of ecology, I mean the education of ecology’s concepts within a scholastic, primarily university, setting and the usage of said concepts for the purpose of research or societal development respectively. I will argue that the study and practice of ecology would benefit from an inclusion of hermeneutics into its study in the scholastic system by way of developing nuanced understandings of oneself and their relation to the environment, thereby revealing new horizons of possibility in decision-making in society regarding the environment and oneself. To do this, I begin by using hermeneutic strategies in a reading of Gilgamesh to draw comparisons between Gilgamesh’s journey and the development of human society’s relationship to progress. Juxtaposing the concerns posited by the hermeneutic reading of Gilgamesh with Neil Postman’s claim that our contemporary understanding of the world is helpfully understood as what he calls a “Technopoly,” I argue technology has altered our orientation towards the environment in a way that falsely suggests hermeneutics has no place in ecology or any science. Exploring passages from Martin Heidegger, I then argue how humans’ fundamental relationship to interpretation makes hermeneutics the ground from which ecology is able to rise from. Further exploring passages from Heidegger’s work and exploring the etymology of the words “preserve” and “beforehand,” I argue that not only does hermeneutics allow for the study of ecology, but by studying ecology without it we are left in a state prime for mis-handling the Earth, thus making hermeneutics a crucial part of an education in ecology. I close by providing an example of using hermeneutic practices on two essays by Ralph Waldo Emerson to display how these hermeneutic practices could be used in conjunction with an education in ecology and illustrate the benefits therein.

The use of genetic management in conservation has sparked much debate around the ethical and environmental impacts of the plans. A case study on the conservation of leopard frogs in Arizona was analyzed to better understand the benefits and issues surrounding genetic management plans. The first part of the case focuses on the recent management plan for Chiricahua Leopard Frogs implemented by the Arizona Game and Fish Department. The goal of the plan is to better understand the genetic dynamics of the established Chiricahua Leopard Frog populations to develop a more effective management plan. The second part of the case focuses on the Arizona Game and Fish Department’s management of the Northern Leopard Frog. There was little success with the initial breed and release program of the native species, however a nonnative subspecies of Northern Leopard Frog was able to establish a thriving population. This case study exemplifies the many complications with genetic management plans and the importance of careful assessment of options when deciding on a genetic management plan. Despite the complexity of genetic management plans, it is an important method to consider when discussing the conservation of a species.
