Migration And Colonization Characteristics Of Endophytic Tracer Rhizobia To The Reproductive Organs Of Alfalfa, W. J. Kang, S. L. Shi, Y. T. Zhang, L. Y. Chen

IGC Proceedings (1977-2023)

Legume seeds are the product of long-term natural selection and the co-evolution of rhizobia and seeds. They are more competitive than the native rhizobia in constructing symbiotic nitrogen-fixing systems with host plants. However, the paths and impact factors of rhizobia invasion and migration in plants, as well as colonization in seeds, are unclear. Here, alfalfa cultivars WL343HQ and Gannong 5, and three cyan fluorescent protein-tagged rhizobia (FTR), 3436f, 12531f and gn5f were used as materials. The effects of potassium dihydrogen phosphate (KH2PO4) and fulvic acid (FA) on the migration and colonization of FTR in the reproductive organs of field plants …

Grassland sites are important ecosystems delivering essential ecosystem services such as carbon storage and filtering of water. Adequate management necessitates a better understanding of soil ecological processes in grassland ecosystems. Of special interest is the relationship between soil structure and root development. In a project within the Biodiversity Exploratory Initiative (http://www.biodiversity-exploratories.de), undisturbed soil cores from 31 grassland plots from Swabian Alb Biodiversity exploratory in Germany were investigated by means of X-ray micro computed tomography. This allows the simultaneous determination of soil physical and root parameters in one sample. VG StudioMax® version 2.1 was used to apply a combination of histogram …


Spatio-Temporal Dynamics Of The Dual-Purpose Cattle Value Chain In The Colombian Amazonas, A. Leinert, S. Burkart Feb 2024

Spatio-Temporal Dynamics Of The Dual-Purpose Cattle Value Chain In The Colombian Amazonas, A. Leinert, S. Burkart

IGC Proceedings (1977-2023)

The cattle sector plays an important role in the economy of the Caquetá department, located in the Colombian Amazon. However, the predominantly extensive production system is associated with low productivity and negative environmental impacts, such as land degradation, greenhouse gas emissions, and deforestation. Efforts to introduce improved practices (e.g., improved forages or silvopastoral systems) have been made over the last decades, but adoption rates remain low. Though several studies have analyzed the cattle value chain (VC) to enhance the understanding of adoption barriers, the heterogeneity of farmers has been considered only marginally when trying to explain their adoption behavior. To …

IGC Proceedings (1977-2023)

The potential of grasslands’ fodder production is a crucial management measure, while its quantification is still laborious and costly. Remote sensing technologies, such as hyperspectral field measurements, enable fast and non-destructive estimation. However, such methods are still limited in transferability to other locations or climatic conditions. With this study, we aim to predict forage nutritive value, quantity, and energy yield from hyperspectral canopy reflections of grasslands across three climate zones. We took hyperspectral measurements with a field spectrometer from grassland canopies in temperate, tropical and semi-arid grasslands, and analyzed corresponding biomass samples for their quantity (BM), metabolizable energy content (ME) …

More Than Ethics: Changing Approaches To Research In Human Biology, Agustín Fuentes Feb 2024

More Than Ethics: Changing Approaches To Research In Human Biology, Agustín Fuentes

Human Biology Open Access Pre-Prints

Work in biological anthropology and human biology that engages with, extracts, manipulates, analyzes and disseminates biological data from and associated with people requires serious ethical investment as central to method, theory, and practice. However, ethics is not enough. Moving beyond a call for better (or more) ethics there is a core need for anthropological, historical, anti-racist/anti-colonialist method and theory in dealing with human data (existing, newly collected, and future collections). But there are structures in the academy, historical, financial, hierarchical, discriminatory, that impede sincere and effective actions to make such changes. Encouragingly, calls for structural change, and some actions entailing …

Don't Swab Me!: Limitations Of The Genetic Information Privacy Act In The Modern Genetic Testing Landscape, Ibrahim Al-Gahmi

New Mexico Law Review

In an age where consumers can easily obtain genetic tests by simply sending a saliva or cheek swab sample through the mail and learn more than ever about their DNA and its genetic makeup, it is imperative that measures are established to provide consumers with both control and protection to the privacy of their submitted biological sample and analyzed genetic data. Currently, the landscape of genetic testing, and the resulting genetic information, is regulated by one law in New Mexico. The Genetic Information Privacy Act (NM-GIPA or Act), enacted in 1998, provides general prohibitions on the collection of genetic information …


Sackett V. Environmental Protection Agency, Meridian Wappett Feb 2024

Sackett V. Environmental Protection Agency, Meridian Wappett

Public Land & Resources Law Review

In 2007, the Sacketts began developing a property a few hundred feet from Priest Lake in Northern Idaho by filling their lot with gravel. The EPA determined the lot constituted a federally protected wetland under the WOTUS definition because the lot was near a ditch that fed into a creek flowing into Priest Lake, a navigable intrastate lake. The EPA halted the construction. The Sacketts sued the EPA, arguing the CWA did not apply to their property. The Supreme Court held that the CWA did not apply to the Sacketts property because the CWA only covers wetlands and streams that …
