CHARACTERIZATION OF TWO BACTERIAL ISOLATES, ACHROMOBACTER MUCICOLENS (A2) AND BACILLUS PARAMYCOIDES (A17), AND ANALYSIS OF PLASTIC BIODEGRADATION CAPABILITY
Lennon, Reece (2024-05-10)In this work, two isolates, Achromobacter mucicolens (A2) and Bacillus paramycoides (A17), isolated from naturally weathered plastic enrichment cultures, were studied genetically, morphologically, biochemically and for ... -
The effect of a non-circadian photoperiod on the growth, physiology, and production of a romaine lettuce cultivar
Hughes, Joshua (2022)The circadian rhythm serves to match plant physiology and behavior with the environmental cycles caused by the rotation of the planet. The circadian rhythm contributes towards the structure and function of plants and ... -
ESTABLISHMENT OF A RARE RIPARIAN TREE, ALNUS MARITIMA
Ehardt, Cassie (2016-12-16)Alnus maritima is a rare, riparian tree species showing no recruitment from seeds. We conducted studies to identify factors potentially limiting establishment. First, we surveyed current known populations to determine ... -

Walton, Alexia (2020-06-12)Juniperus virginiana L. (eastern red cedar) is a species of interest throughout North America as a result of its rapid encroachment into historic grasslands, but the effects of nurse trees on J. virginiana seedling recruitment ... -
Quantifying spatial-temporal stability to drought in a semi-arid shortgrass prairie ecosystem
Allen, Eric (2022-05)Drought is known to cause negative ecological impacts in grasslands, with areas prone to drought expected to experience increases in both severity and frequency in the coming years. Cimarron County, Oklahoma is located at ... -
SHIFTS OF SOIL MICROBIAL COMMUNITIES IN ALASKAN TUNDRA IN RESPONSE TO LONG-TERM WARMING
Wang, Cong (2016-08)Permafrost regions store about 33% of the world’s soil organic carbon, and are believed to rapidly respond to global warming. The degradation and release of previously stored organic carbon stocks lead to positive feedbacks, ...
