Controlling Lethal Browning Of Hemarthria Compressa Tissue Cultures, Chunhua Yang, Yaohua Xu, Lingzhi Chen, Yifang Sui
IGC Proceedings (1977-2023)
Hemarthria compressa is an important warm-season forage grass for use in Southwest China. However, due to poor seed set, it is propagated by vegetative cuttings of stolons, rhizomes, and nodal sections. The in vitro propagation of H. compressa is still faced with difficulties including blackening or browning of tissues prior to culturing due to the oxidation of phenolic compounds by polyphenolic oxidase enzyme present in excised tissue (Yang et al. 2008). The objectives of the study were to investigate possible means of successful initiation of cultures through elimination of phenolic browning.

Leaf Growth And Senescence Rates In Brown-Back Wallaby Grass, Rytidosperma Duttonianum, Helen G. Daily, Shaun Lisson, Kerry L. Bridle, Peter A. Lane, Stuart Anderson, Ross Corkrey
IGC Proceedings (1977-2023)
Knowledge of leaf turnover in grasses is necessary to model curing (the accumulation of dead material in the sward), which is not well represented in current pasture growth models, nor for many Australian native species. Leaf turnover begins with the appearance of successive leaves, which elongate until typically, a leaf ligule develops to indicate a mature, fully expanded length. Green leaf life span extends from appearance to the beginning of senescence, which ultimately leads to death (Fig. 1). Here, the individual rates of leaf growth and senescence for the Australian native brown-back wallaby grass, Rytidosperma duttonianum (Cashmore) Connor & Edgar, …

Basin Wildrye (Leymus Cinereus) Pooled Tetraploid Accessions For U.S. Intermountain West Rangeland Reclamation, Stanford A. Young, Jason Vernon, Nancy Shaw
IGC Proceedings (1977-2023)
Basin wildrye (Leymus cinereus [Scribn. & Merr.] Á. Löve) is an important perennial, hardy, long-lived, cool season C3 native grass of rangeland plant communities throughout much of western United States and Canada. All classes of livestock and wildlife, including large and small birds and mammals, utilise the grass year round for food and protection due to its 2-3 m tall, stiff stature which provides standing winter cover. Though occurring in precipitation areas of 150-500 mm and elevations of 600 to 3,000 m, it is usually found in deep, well-drained soils of high water holding capacity along drainage areas. Seedling …
Summer Dormancy Expression In The Australian Native Grass Elymus Scaber, Matthew Newell, Richard C. Hayes, Jim Virgona, Philip Larkin
Summer Dormancy Expression In The Australian Native Grass Elymus Scaber, Matthew Newell, Richard C. Hayes, Jim Virgona, Philip Larkin
IGC Proceedings (1977-2023)
Complete summer dormancy is associated with plant senescence in late spring-summer even though soil moisture is non-limiting. The trait is well understood in exotic temperate grasses for persistence in environments which experience frequent summer droughts (Annicchiarico et al. 2011). However, the trait appears to be uncommon in Australian native grasses (Culvenor 2009). The C3 native perennial grass, Elymus scaber, is broadly adapted across a wide range of climatic zones and soil types in south eastern Australia (Johnston et al. 2001) and has been described as displaying strong summer dormancy (Mitchell et al. 2001). However, the reports …

Challenges To Domesticating "Native" Forage Legumes, James P. Muir, José C. B. Dubeux Jr., Mércia V. F. Dos Santos, Inacio C. Maposse, William D. Pitman, Twain J. Butler
IGC Proceedings (1977-2023)
If ruminant production from cultivated and natural grasslands is to depend less on petroleum-based products, forage legumes must serve as protein sources. Commercially available legumes for warm-dry climate grasslands are, however, very limited and resources available for developing such legumes are inadequate. Indeterminate flowering and dehiscent seed pods combined with the need for specialized seed harvesting equipment are major impediments (Butler and Muir 2012). Warm climates often present environmental challenges such as poor rainfall distribution, extended dry seasons, temperature extremes and aggressive grass species (Muir et al. 2011). Erosion of indigenous knowledge and replacement with inappropriate land management approaches …

Seeding Rate And Row-Spacing Effects On Seed Yield And Yield Components Of Leymus Chinensis (Trin.) Tzvel., Yunhua Han, Xianguo Wang, Tianming Hu, Zhenlei Zhu, Zhengwei Wang, Ying Wang
IGC Proceedings (1977-2023)
Chinese sheepgrass (Leymus chinensis (Trin.) Tzvel.) is widely distributed in the eastern portion of the Inner Mongolian Plateau and the Songnen Grassland of China. This grass is highly salt, cold and drought tolerant and has been the major source of forage for cows and other ruminants in China (Gao et al. 2012). Seed yield of this grass is very low under native conditions because of the low heading percentage and percentage of seed set (Wang et al. 2010). The Hexi Corridor, located in China’s northwestern Gansu Province, is the seed production center of China because of its …

IGC Proceedings (1977-2023)
Past mismanagement, overgrazing, invasive weedy species, wildfires, marginal crop production, mineral and energy extraction, recreation and global climate change are challenges currently facing rangelands (Pierson et al. 2011). These disturbances may lead to long-term reductions in biodiversity, altered nutrient and water cycling, diminished forage production for livestock and wildlife, increased wildfire frequency and increased soil erosion and stream sedimentation (Sheley et al. 2008). Rangeland revegetation with desirable plant materials may be required to improve degraded conditions, speed recovery, and prevent further erosion and degradation. There is a critical need for plant materials to restore and revegetate rangeland ecosystems. …

IGC Proceedings (1977-2023)
The objective of this paper was to provide a brief overview of native plant use and development including examples of native plant research being conducted in Canada. There is increasing interest in native plants in various countries. Currently, native plants are used in reclamation, biomass biofuel production, forage seeding, habitat restoration, and water and soil conservation efforts. Many countries have active programs for native plant preservation and new germplasm development, but seed cost, seed quality, and ease of establishment are still challenges for large-scale use. Many improved native plant germplasms have been released in recent years. In some countries, legislation …

Air-stable iron carbonyl compounds bearing cyclopentadienone ligands with varying substitution were explored as catalysts in dehydrogenative diol lactonization reactions using acetone as both the solvent and hydrogen acceptor. Two catalysts with trimethylsilyl groups in the 2- and 5-positions, [2,5-(SiMe3)2-3,4-(CH2)4(η4-C4C═O)]Fe(CO)3 (1) and [2,5-(SiMe3)2-3,4-(CH2)3(η4-C4C═O)]Fe(CO)3 (2), were found to be the most active, with 2 being the most selective in the lactonization of diols containing both primary and secondary alcohols. Lactones containing five-, six-, and seven-membered rings were successfully synthesized, and no over-oxidations to carboxylic acids were detected. The lactonization of unsymmetrical diols containing two …

Reduced body size and accelerated life cycle due to warming are considered major ecological responses to climate change with fitness costs at the individual level. Surprisingly, we know little about how relevant ecological factors can alter these life history trade‐offs and their consequences for individual fitness. Here, we show that food modulates temperature‐dependent effects on body size in the water flea Daphnia magna and interacts with temperature to affect life history parameters. We exposed 412 individuals to a factorial manipulation of food abundance and temperature, tracked each reproductive event, and took daily measurements of body size from each individual. High …
23andeveryone: Privacy Concerns With Law Enforcement’S Use Of Genealogy Databases To Implicate Relatives In Criminal Investigations, Shanni Davidowitz
23andeveryone: Privacy Concerns With Law Enforcement’S Use Of Genealogy Databases To Implicate Relatives In Criminal Investigations, Shanni Davidowitz
Brooklyn Law Review
The discovery of DNA typing in the 1980s transformed law enforcement’s ability to exonerate innocent suspects, while implicating those who are guilty, with “the power of a silent biological witness at the crime scene.” This transformation, coupled with the new trend of law enforcement’s use of genealogy databases, has created legal issues that police officers, prosecutors, genealogy companies, and policy makers are all currently trying to navigate. The technological advancement comes with serious ethical and privacy concerns, including fear of the establishment of a “genetic panopticon.” General concern exists that if a “genetic panopticon” comes to fruition, the government can …

“Hey Alexa, Do Consumers Really Want More Data Privacy?”: An Analysis Of The Negative Effects Of The General Data Protection Regulation, Katherine M. Wilcox
Brooklyn Law Review
Recent news articles discuss the flooding of email inboxes with lengthy terms and condition updates, viral videos of Mark Zuckerberg’s public Cambridge Analytica hearing before Congress, and the phenomenon of internet advertisements appearing for items that consumers merely searched for on Google a day prior. Effective as of May 25, 2018, the European Union’s General Data Protection Regulation (GDPR) established a framework that sets legal standards targeted at businesses and other data collectors to dramatically increase data privacy protections for citizens of the EU. Consumers, however, do not seem to appreciate these increased protections, as they rarely read the updated …

Department of Biological & Biomedical Sciences
Background: A shift in the healthcare system towards the centralization of common yet costly surgeries, such as total hip arthroplasty (THA), to high-volume centers of excellence, is an attempt to control the economic burden while simultaneously enhancing patient outcomes. The "volume-outcome" relationship suggests that hospitals performing more treatment of a given type exhibit better outcomes than hospitals performing fewer. This theory has surfaced as an important factor in determining patient outcomes following THA. We performed a systematic review with meta-analyses to review the available evidence on the impact of hospital volume on outcomes of THA.
Materials and methods: We conducted …

Chipping Away At Compliance: How Compliance Programs Lose Legitimacy And Its Impact On Unethical Behavior, David Hess
Chipping Away At Compliance: How Compliance Programs Lose Legitimacy And Its Impact On Unethical Behavior, David Hess
Brooklyn Journal of Corporate, Financial & Commercial Law
Employee perceptions of an organization’s compliance program are critical. A program that has lost legitimacy with its employees is not just ineffective, but it creates more harm than good by leading to more unethical behavior. This Article identifies ways in which compliance programs can start to lose legitimacy, explains how that lost legitimacy leads to increased wrongdoing, and then concludes by setting out some basic reforms focused on helping stop this downward spiral and protecting the legitimacy of the compliance function.
