Cisnormative Language and Erasure of Trans* and Genderqueer Student Representation in Biology Education Research.

Trans* and genderqueer student retention and liberation is integral for equity in undergraduate education. While STEM leadership calls for data-supported systemic change, the erasure and othering of trans* and genderqueer identities in STEM research perpetuates cisnormative narratives. We sought to characterize how sex and gender data are collected, analyzed, and described in biology education research.

Methane emissions from forested closed landfill sites: Variations between tree species and landfill management practices.

Trees in natural and managed environments can act as conduits for the transportation of methane (CH) from below ground to the atmosphere, bypassing oxidation in aerobic surface soils. Tree stem emissions from landfill sites exhibit large temporal and spatial variability in temperate environments and can account for approximately 40% of the total surface CH flux. Emission variability was further investigated in this study by measuring CH and CO fluxes from landfill sites with different management strategies and varying tree species over a 7-month period.

Methane emissions from trees planted on a closed landfill site.

Trees have morphological adaptations that allow methane (CH) generated below ground to bypass oxidation in aerobic surface soils. This natural phenomenon however has not been measured in a landfill context where planted trees may alter the composition and magnitude of CH fluxes from the surface. To address this research gap, we measured tree stem and soil greenhouse gas (GHG) emissions (CH and CO) from a closed UK landfill and comparable natural site, using an off-axis integrated cavity output spectroscopy analyser and flux chambers.

Concentration and composition of bioaerosol emissions from intensive farms: Pig and poultry livestock.

Intensive farming is widespread throughout the UK and yet the health effects of bioaerosols which may be generated by these sites are currently not well researched. A scoping study was established to measure bioaerosols emitted from intensive pig (n = 3) and poultry farms (n = 3) during the period 2014-2015. The concentration of culturable mesophilic bacteria, Gram-negative bacteria, Staphylococcus spp.

Scoping studies to establish the capability and utility of a real-time bioaerosol sensor to characterise emissions from environmental sources.

A novel dual excitation wavelength based bioaerosol sensor with multiple fluorescence bands called Spectral Intensity Bioaerosol Sensor (SIBS) has been assessed across five contrasting outdoor environments. The mean concentrations of total and fluorescent particles across the sites were highly variable being the highest at the agricultural farm (2.6 cm and 0.
