Additive Negative Effects Of Decadal Warming And Nitrogen Addition On Grassland Community Stability, Q. Wu, G. D. Han, S. X. Chang, H. Y. Ren
Additive Negative Effects Of Decadal Warming And Nitrogen Addition On Grassland Community Stability, Q. Wu, G. D. Han, S. X. Chang, H. Y. Ren
IGC Proceedings (1997-2023)
Much recent research has explored how global warming and increased nitrogen (N) deposition, two important components of global environmental changes, influence the structure and functioning of natural ecosystems. However, how ecosystem dynamics respond to the combination of long-term warming and N enrichment remains largely unexplored. The impact of warming and N addition on the temporal stability of plant communities were investigated in a decade-long field experiment. The study was conducted in northern China in a desert steppe, using a split-plot design with warming as the main-plot factor and N addition as the splitplot factor. Long-term warming and N addition had …

Perceptions Of Gauteng Beef Farmers On Significance Of Practising Climate Smart Agriculture, S. T. Jiyana, K-J. Leeuw, Abubeker Hassen, Ignatius V. Nsahlai
IGC Proceedings (1997-2023)
Farmers are crucial role-players in agriculture, especially in beef farming. Daily farm activities affect climate change, either negatively or positively. Therefore, farmers’ ability to relate climate change with farm activities is highly imperative. A study was conducted to investigate perceptions of Gauteng beef farmers on significance of practising climate smart agriculture (CSA). Semi-structured key informant interviews were conducted with 57 beef cattle farmers from three areas (Bronkhorstspruit, Rust de Winter and Cullinan) of Tshwane region (Gauteng province). A fully detailed ethical statement was used to explain the study and request farmers’ participation. Data analysis was done using a Statistical Package …

Long-Term N Addition, Not Warming, Increases Net Ecosystem Co2 Exchange In A Desert Steppe In Northern China, Guodong Han, Qian Wu
IGC Proceedings (1997-2023)
Grasslands cover a major part of the global terrestrial area and provide important ecosystem functions such as sequestration of carbon (C). Desert steppes are unique ecosystems with properties in between desert and grasslands. They are considered to be vulnerable ecosystems that are at risk of desertification due to global change. To provide a robust prediction of the effect of climate warming and increased nitrogen (N) deposition on desert steppe, long-term studies that capture the annual variation in precipitation are needed. We conducted a 12-year field experiment in a desert steppe which showed that warming did not change ecosystem C exchange …

Planet At Risk From Grazing Animals?, Albrecht F. Glatzle
IGC Proceedings (1997-2023)
The famous FAO report “Livestock’s Long Shadow” (Steinfeld et. al. 2006) and hundreds of subsequent publications blamed domestic livestock, in general, and grassland-based production systems in the (sub) tropics, in particular, of causing serious environmental hazards such as climate change, claiming that 18% of anthropogenic greenhouse gas (GHG) emissions are from livestock, more than from the transport sector. Few reviews challenged this claim, and those that did received little attention from the media. Pitseky et al. (2009) revealed the double standard applied by the FAO in this matter. Whereas for livestock products a full life cycle assessment for …

Designing Resilient And Sustainable Grasslands For A Drier Future: Adaptive Strategies, Functional Traits And Biotic Interactions, Florence Volaire, Karim Barkaoui, Mark Norton
IGC Proceedings (1997-2023)
In many regions of the world, such as Southern Europe and most Mediterranean areas, the frequency and magnitude of droughts and heat waves are expected to increase under global warming and will challenge the sustainability of both native and sown grasslands. To analyze the adaptive strategies of species, genotypes and cultivars, we aim both: (1) to understand the composition and functioning of natural grasslands; and (2) to propose ideotypes of cultivars and optimal composition for mixtures of species/genotypes under water deficit and high temperatures. This review presents a conceptual framework to analyze adaptive responses of perennial herbaceous species, starting from …
The Effects Of Climate Science Literacy And Cultural Polarization Around Climate Change Risk Perception, Gabriel R. Young, Helen R. Neill
The Effects Of Climate Science Literacy And Cultural Polarization Around Climate Change Risk Perception, Gabriel R. Young, Helen R. Neill
Graduate Research Symposium (GCUA) (2010 - 2017)
Science communicators have struggled to provide meaningful information about climate change due to the complex nature of the problem and the polarized political and media landscapes, and yet, a well informed public is a crucial element to both public acceptance and policy initiatives aimed at climate change mitigation. Current literature suggests that scientific literacy actually increases cultural polarization around the issue of climate change (Kahan, 2012). This study adds to the literature by testing the hypothesis that climate change risk perception is more heavily tied to climate science literacy than general science literacy when controlling for cultural worldviews. We use …
Investigating Perspectives Of Rural Nevadans On Climate Change Solutions, Tricia Dutcher
Investigating Perspectives Of Rural Nevadans On Climate Change Solutions, Tricia Dutcher
Graduate Research Symposium (GCUA) (2010 - 2017)
Rural perspectives are important for the issue of climate change. Rural areas are high concentrations of active voters who deny the problem of anthropogenic climate change. Rural residents also face decisions about inviting large, utility scale renewable energy developments in their areas. This research examines rural Nevadan’s perspectives on climate change to offer insights about the relationship between climate change perceptions and communication strategies. The research offers policy implications that address context specific issues, solution-oriented dialogue, and interest matching to mitigate anthropogenic climate change.
Has Recent Climate Change Caused A Genetic Bottleneck In A Sierra Nevada Population Of The Bushy-Tailed Woodrat?, Mitchell Gritts, Angela D. Hornsby, Majorie D. Matocq
Has Recent Climate Change Caused A Genetic Bottleneck In A Sierra Nevada Population Of The Bushy-Tailed Woodrat?, Mitchell Gritts, Angela D. Hornsby, Majorie D. Matocq
Festival of Communities: UG Symposium (Posters)
Many montane species respond to climate change by shifting their range upslope as temperatures at lower elevations increase. An elevation range shift causes a range contraction that may result in a population bottleneck. Joseph Grinnell surveyed the fauna along the Yosemite transect from 1914 to 1920. In 2003 Craig Moritz and his colleagues began to resurvey the Yosemite transect to assess the faunal change during a century of climate change. The bushy-tailed woodrat suffered severe range contraction and population bottleneck between the two surveys. I will use evolutionary models to determine if the population has suffered a genetic bottleneck.
Similarity Of Climate Change Data For Antarctica And Nevada, Corbin Benally, Shahram Latifi, Karletta Chief
Similarity Of Climate Change Data For Antarctica And Nevada, Corbin Benally, Shahram Latifi, Karletta Chief
Undergraduate Research Opportunities Program (UROP)
The correlation between temperature and carbon dioxide concentration in the past one hundred years is studied. Separate graphs containing data from Vostok, Antarctica and the Mojave desert/mountain west (Nevada region) are presented. Using data obtained from these graphs, an attempt is made to explain the results and investigate the similarity of these results for Antarctica and Nevada. The importance of this study lies in the fact that if data show the same trend in the two regions, many findings for climate change in Antarctica may readily be validated and employed for Nevada.

MORNING CONCURRENT TRACK 2: CREATION AND CORRECTION OF MYTHS ABOUT GLOBAL WARMING Moderator Robert Futrell Student Union Room 211 Matthew Lachniet – Global Warming Misconceptions and Myths: Barriers and Opportunities for Communicating Climate Change Science to a Non-scientific Audience Abstract: Opinions on an anthropogenic influence in global warming abound. Within the non-scientific public, the strength of one’s opinion commonly seems to be in inverse proportion to their knowledge of climate science. One reason for this disconnect between reality and opinion is the persistence of many climate change myths in popular knowledge of global warming. These myths are regularly propagated in …
