Plant–Plant Interactions Change During Succession On Nurse Logs In A Northern Temperate Rainforest, Carrie L. Woods, Katy Maleta, Kimmy Ortmann Jul 2021

Plant–Plant Interactions Change During Succession On Nurse Logs In A Northern Temperate Rainforest, Carrie L. Woods, Katy Maleta, Kimmy Ortmann

All Faculty Scholarship

Plant–plant interactions change through succession from facilitative to competitive. At early stages of succession, early-colonizing plants can increase the survival and reproductive output of other plants by ameliorating disturbance and stressful conditions. At later stages of succession, plant interactions are more competitive as plants put more energy toward growth and reproduction. In northern temperate rainforests, gap dynamics result in tree falls that facilitate tree regeneration (nurse logs) and bryophyte succession. How bryophyte-tree seedling interactions vary through log succession remains unclear. We examined the relationships of tree seedlings, bryophyte community composition, bryophyte depth, and percent canopy cover in 166 1.0 m2 …


Wildfire As A Natural Stressor And Its Effect On Female Phenotype And Ornament Development, Stacey L. Weiss, Robert M. Brower Jun 2021

Wildfire As A Natural Stressor And Its Effect On Female Phenotype And Ornament Development, Stacey L. Weiss, Robert M. Brower

Controlled low-intensity fires are commonly used in ecosystem management for both habitat restoration and wildfire management. Animals in those ecosystems may respond to fire by shifting energy allocation away from reproduction and growth, and toward maintenance. Stress-induced shifts in energy allocation may affect the expression of condition-dependent sexual signals, which are sensitive to energetic and physiological trade-offs mediated by glucocorticoids. Here, we examine the effect of fire on ornament expression, corticosterone, and other phenotypic traits in a population of striped plateau lizards, Sceloporus virgatus, affected by the Horseshoe 2 Fire in the Chiricahua Mountains, Arizona, USA. The condition-dependent female ornament …


The Intellectual Property Of Covid-19, Ana Santos Rutschman Jan 2021

The Intellectual Property Of Covid-19, Ana Santos Rutschman

All Faculty Scholarship

The response to COVID-19 is indissolubly tied to intellectual property. In an increasingly globalized world in which infectious disease pathogens travel faster and wider than before, the development of vaccines, treatments and other forms of medical technology has become an integral part of public health preparedness and response frameworks. The development of these technologies, and to a certain extent the allocation and distribution of resulting outputs, is informed by intellectual property regimes. These regimes influence the commitment of R&D resources, shape scientific collaborations and, in some cases, may condition the widespread availability of emerging technologies. As seen throughout this chapter, …


Covid-19 Employee Health Checks, Remote Work, And Disability Law, Elizabeth Pendo Jan 2021

Covid-19 Employee Health Checks, Remote Work, And Disability Law, Elizabeth Pendo

All Faculty Scholarship

The Americans with Disabilities Act (ADA) prohibits discrimination against people with disabilities, about 61 million individuals in the U.S. The law’s protections in the workplace are especially important during COVID-19, which has worsened pre-existing disparities experienced by people with disabilities. The ADA also applies to new strategies to reduce the risk of COVID-19 infection in the workplace. This Chapter will focus on two strategies that impact individuals with and without disabilities – employee health screening, testing and vaccination policies, and new or expanded remote work programs.
