How do primates, humans included, deal with novel problems that arise in interactions with other group members? Despite much research regarding how animals and humans solve social problems, few studies have utilized comparable procedures, outcomes, or measures across different species. Thus, it is difficult to piece together the evolution of decision making, including the roots from which human economic decision making emerged. Recently, a comparative body of decision making research has emerged, relying largely on the methodology of experimental economics in order to address these questions in a cross-species fashion. Experimental economics is an ideal method of inquiry for this …
The Importance Of Female Choice: Evolutionary Perspectives On Constraints, Expressions, And Variations, David Frederick, Tania A. Reynolds, Maryanne L. Fisher
The Importance Of Female Choice: Evolutionary Perspectives On Constraints, Expressions, And Variations, David Frederick, Tania A. Reynolds, Maryanne L. Fisher
Psychology Faculty Books and Book Chapters
This chapter introduces the reader to some of the influential perspectives on female mate choice in human evolutionary biology, including parental investment theory. We then present two key theories in evolutionary psychology that have been applied to understand variations in women’s mating preferences and choices: sexual strategies theory and strategic pluralism theory. Although the importance of female choice has gained widespread acceptance in the biological sciences, the influence that female choice has on mating systems can be limited by many factors, such as control over mating decisions by parents and men’s control over women’s sexuality. Despite these constraints on female …
The Physiology Of Invasive Plants In Low-Resource Environments, Jennifer L. Funk
The Physiology Of Invasive Plants In Low-Resource Environments, Jennifer L. Funk
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
While invasive plant species primarily occur in disturbed, high-resource environments, many species have invaded ecosystems characterized by low nutrient, water, and light availability. Species adapted to low-resource systems often display traits associated with resource conservation, such as slow growth, high tissue longevity, and resource-use efficiency. This contrasts with our general understanding of invasive species physiology derived primarily from studies in high-resource environments. These studies suggest that invasive species succeed through high resource acquisition. This review examines physiological and morphological traits of native and invasive species in low-resource environments. Existing data support the idea that species invading low-resource environments possess traits …
Solid-Phase Organic Matter Reduction Regulates Anaerobic Decomposition In Bog Soil, Jason K. Keller, Kimberly K. Takagi
Solid-Phase Organic Matter Reduction Regulates Anaerobic Decomposition In Bog Soil, Jason K. Keller, Kimberly K. Takagi
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Peatlands store globally significant amounts of carbon and are important sources of the greenhouse gas methane (CH4) to the atmosphere. However, for reasons which are not well understood, many peatland soils produce smaller amounts of CH4 than theoretically predicted, and carbon dioxide (CO2) produced during anaerobic decomposition in peatland soils cannot be accounted for by commonly measured microbial processes. Here we show that the reduction of solid-phase organic matter (i.e., humic substances) suppresses CH4 production in a bog soil and can be responsible for 33–61% of the total carbon mineralization in this soil. These results demonstrate that the reduction of …
Leaf Traits Within Communities: Context May Affect The Mapping Of Traits To Function, Jennifer L. Funk, William K. Cornwell
Leaf Traits Within Communities: Context May Affect The Mapping Of Traits To Function, Jennifer L. Funk, William K. Cornwell
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
The leaf economics spectrum (LES) has revolutionized the way many ecologists think about quantifying plant ecological trade-offs. In particular, the LES has connected a clear functional trade-off (long-lived leaves with slow carbon capture vs. short-lived leaves with fast carbon capture) to a handful of easily measured leaf traits. Building on this work, community ecologists are now able to quickly assess species carbon-capture strategies, which may have implications for community-level patterns such as competition or succession. However, there are a number of steps in this logic that require careful examination, and a potential danger arises when interpreting leaf-trait variation among species …
Differential Allocation To Photosynthetic And Non-Photosynthetic Nitrogen Fractions Among Native And Invasive Species, Jennifer L. Funk, Lori A. Glenwinkle, Lawren Sack
Differential Allocation To Photosynthetic And Non-Photosynthetic Nitrogen Fractions Among Native And Invasive Species, Jennifer L. Funk, Lori A. Glenwinkle, Lawren Sack

Invasive species are expected to cluster on the “high-return” end of the leaf economic spectrum, displaying leaf traits consistent with higher carbon assimilation relative to native species. Intra-leaf nitrogen (N) allocation should support these physiological differences; however, N biochemistry has not been examined in more than a few invasive species. We measured 34 leaf traits including seven leaf N pools for five native and five invasive species from Hawaii under low irradiance to mimic the forest understory environment. We found several trait differences between native and invasive species. In particular, invasive species showed preferential N allocation to metabolism (amino acids) …
Seeds Of Resistance: Towards A Revolutionary Critical Ecopedagogy, Peter Mclaren
Seeds Of Resistance: Towards A Revolutionary Critical Ecopedagogy, Peter Mclaren
Education Faculty Articles and Research
The death throes of mother earth are imminent unless we decelerate the planetary ecological crisis. Critical educators, who have addressed with firm commitment topics of race, class, gender, sexuality, disability, and other social justice issues are casting their eyes to the antagonism between capitalism and nature to ask themselves how we can rationally regulate the human metabolic relation with nature. As the global power complex reduces human life and mother earth to mere production and consumption, critical revolutionary ecopedagogy is developing new, unalienated forms of selfpresence. Ecopedagogy is inspired by and inspires a new social arc, rooted in practices of …
