Characterizing Nematode Communities In Carrot Fields And Their Bioindicator Role For Soil Health, A. Habteweld, D. Brainard, A. Kravchencko, Parwinder Grewal, H. Melakeberhan

School of Earth, Environmental, & Marine Sciences Faculty Publications

Plant-parasitic nematodes (PPN) are known to reduce quality and yield of carrot (Daucus carota var. sativus). Efficient nematode management begins with identifying the predominant PPN present in a given field before taking any management decisions. The management decisions should also consider suppression of PPN and promotion of beneficial nematodes represented by bacterivores, fungivores, omnivores, and predators to improve soil health conditions. We selected four carrot fields suspected to have PPN problems in Mason and Oceana counties in Michigan, USA. The counties are located in the major carrot-producing regions of Michigan. These sites have not been previously sampled for …

School of Earth & Environment Departmental Research

Agricultural data are crucial to many aspects of production, commerce, and research involved in feeding the global community. However, in most agricultural research disciplines standard best practices for data management and publication do not exist. Here we propose a set of best practices in the areas of peer review, minimal dataset development, data repositories, citizen science initiatives, and support for best data management. We illustrate some of these best practices with a case study in dairy agroecosystems research. While many common, and increasingly disparate data management and publication practices are entrenched in agricultural disciplines, opportunities are readily available for promoting …

76-Year Decline And Recovery Of Aspen Mediated By Contrasting Fire Regimes: Long-Unburned, Infrequent And Frequent Mixed-Severity Wildfire, Cerena J. Brewen, John-Pascal Berrill, Martin W. Ritchie, Kevin Boston, Christa M. Dagley, Bobette Jones, Michelle Coppoletta, Coye L. Burnett

Aspen Bibliography

Quaking aspen (Populus tremuloides) is a valued, minor component on northeastern California landscapes. It provides a wide range of ecosystem services and has been in decline throughout the region for the last century. This decline may be explained partially by the lack of fire on the landscape due to heavier fire suppression, as aspen benefit from fire that eliminates conifer competition and stimulates reproduction through root suckering. However, there is little known about how aspen stand area changes in response to overlapping fire. Our study area in northeastern California on the Lassen, Modoc and Plumas National Forests has …

Faith, Farming And Food Justice, Catherine Curran

Charles Rice Post-Graduate Research Fellowship

Through a liberationist lens, religion and social justice are more similar than different. Food illuminates opportunities for building collective agency and community resilience in which religion and social justice might serve one another (White 2018). Specifically, faith communities can contribute to local food systems by using church-owned lands to provide access to farmland for beginning and BIPOC farmers, improve access to fresh, healthy produce, and enhance food security (FaithLands 2021). Faith communities are shifting mindsets from charity to justice and scarcity to abundance while addressing rural child hunger (Lietz-Bilecky 2020). Overall, this paper explores unique ways the Christian food movement …
