Studies of animal contests often focus solely on a single static measurement of fighting ability, such as the size or the strength of the individual. However, recent studies have highlighted the importance of individual variation in the dynamic behaviors used during a fight, such as, assessment strategies, decision making, and fine motor control, as being strong predictors of the outcome of aggression. Here, I combined morphological and behavioral data to discover how these features interact during aggressing interactions in male virile crayfish, Faxonius virilis. I predicted that individual variation in behavioral skill for decision making (i.e., number of strikes thrown), would determine the outcome of contest success in addition to morphological measurements (e.g. body size, relative claw size). To evaluate this prediction, I filmed staged territorial interactions between male F. virilis and later analyzed trial behaviors (e.g. strike, pinches, and bout time) and aggressive outcomes. I found very little support for skill to predict win/loss outcome in trials. Instead, I found that larger crayfish engaged in aggression for longer compared to smaller crayfish, but that larger crayfish did not engage in a greater number of claw strikes or pinches when controlling for encounter duration. Future studies should continue to investigate the role of skill, by using finer-scale techniques such as 3D tracking software, which could track advanced measurements (e.g. speed, angle, and movement efficiency). Such studies would provide a more comprehensive understanding of the relative influence of fighting skill technique on territorial contests.
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.
