Is Mitigation Of Drought Stress By Zinc Oxide Nanoparticles Driven By A Nano-Specific Mechanism Or Mitigation Of Micronutrient Deficiency?, Justin Deakin

Student Research Symposium

It has been reported that zinc oxide (ZnO) nanoparticles (NPs) can promote drought tolerance in crops when used as soil amendments. However, many of these experiments were conducted in Zn-deficient growth media with no comparison to currently available Zn fertilization methods, making it unclear if the benefits from adding ZnO NPs were caused by a nano-specifc mechanism or simply by the mitigation of a micronutrient deficiency. A review of the literature shows that of 12 published experiments considering the effects of ZnO NPs on plant health, 5 out of 6 studies that did not include a comparison to currently available …

Jurnal Kultivasi

Terdapat permasalahan dan kendala produksi padi (Oryza sativa L.) seperti luas lahan yang semakin sempit juga sistem budidaya yang masih tradisional. Sawah dataran medium dapat dijadikan perluasan lahan meskipun suhu lebih rendah dibandingkan dataran rendah yang menyebabkan pertumbuhan dan hasil rendah. Perlakuan sistem tanam Legowo dengan penggunaan kultivar unggul diharapkan mampu meningkatkan hasil padi di dataran medium. Penelitian ini bertujuan untuk mempelajari interaksi dari sistem tanam Legowodengan benih padi kultivar unggul (Ciherang, IR64, dan Mekongga). Penelitian dilaksanakan pada bulan Desember 2019 – Mei 2020 di lahan persawahan Bojongsoang, Kab. Bandung, Jawa Barat dengan ketinggian 662 meter di atas permukaan laut. …

Widespread Mortality Of Trembling Aspen (Populus Tremuloides) Throughout Interior Alaskan Boreal Forests Resulting From A Novel Canker Disease, Roger W. Ruess, Loretta M. Winton, Gerard C. Adams

Aspen Bibliography

Over the past several decades, growth declines and mortality of trembling aspen throughout western Canada and the United States have been linked to drought, often interacting with outbreaks of insects and fungal pathogens, resulting in a “sudden aspen decline” throughout much of aspen’s range. In 2015, we noticed an aggressive fungal canker causing widespread mortality of aspen throughout interior Alaska and initiated a study to quantify potential drivers for the incidence, virulence, and distribution of the disease. Stand-level infection rates among 88 study sites distributed across 6 Alaska ecoregions ranged from < 1 to 69%, with the proportion of trees with canker that were dead averaging 70% across all sites. The disease is most prevalent north of the Alaska Range within the Tanana Kuskokwim ecoregion. Modeling canker probability as a function of ecoregion, stand structure, landscape position, and climate revealed that smaller-diameter trees in older stands with greater aspen basal area have the highest canker incidence and mortality, while younger trees in younger stands appear virtually immune to the disease. Sites with higher summer vapor pressure deficits had significantly higher levels of canker infection and mortality. We believe the combined effects of this novel fungal canker pathogen, drought, and the persistent aspen leaf miner outbreak are triggering feedbacks between carbon starvation and hydraulic failure that are ultimately driving widespread mortality. Warmer early-season temperatures and prolonged late summer drought are leading to larger and more severe wildfires throughout interior Alaska that are favoring a shift from black spruce to forests dominated by Alaska paper birch and aspen. Widespread aspen mortality fostered by this rapidly spreading pathogen has significant implications for successional dynamics, ecosystem function, and feedbacks to disturbance regimes, particularly on sites too dry for Alaska paper birch.

Historic Declines In Growth Portend Trembling Aspen Death During A Contemporary Leaf Miner Outbreak In Alaska, Melissa A. Boyd, Logan T. Berner, Adrianna C. Foster, Scott J. Goetz, Brendan M. Rogers, Xanthe J. Walker, Michelle C. Mack

Aspen Bibliography

Climate change-driven droughts and insect outbreaks are becoming more frequent and widespread, increasing forest vulnerability to mortality. By addressing the impacts of climate and insects on tree growth preceding death, we can better understand tree mortality risk under a changing climate. Here, we used tree stature and interannual growth (basal area increment; BAI) to assess processes leading to trembling aspen (Populus tremuloides) survival or mortality during an unprecedented leaf miner (Phyllocnistis populiella) outbreak in boreal North America. We identified eight sites (22 plots) in the longest running forest monitoring network in Alaska, spanning ~350 km of …

High Tunnel Pest Management - Aphids, Nick Volesky, Zachery R. Schrumm

All Current Publications

Aphids are a common pest found on high tunnel crops such as fruits, vegetables, ornamentals, grasses, and weeds. Four aphid species commonly found in Utah in high tunnels are green peach aphid (Myzus persicae), melon aphid (Aphis gossypii), potato aphid (Macrosiphum euphorbiae), and cabbage aphid (Brevicoryne brassicae). This fact sheet describes different aphids and reviews the aphid life cycle. It also addresses how to monitor for damage caused by aphids and cultural, biological, and chemical controls.

Eclp Invasive Plant Project: Spot The Invaders, Aida Washburn

Showcase of Osprey Advancements in Research and Scholarship (SOARS)

An Environmental Center Leadership Program Project

Amelia Island is home to many beautiful native plants, but some invasive species have taken residence in the beach area and caused issues to the ecological system. The invasive plants outcompete our native species and can disrupt the shore bird and sea turtle nesting sites. Invasive plants also destabilize our dunes. A native plant is identified as a species that has naturally existed in each place for an extended length of time. Whereas an invasive species displaces and prevents native species from establishing. The goal of this project was to remove invasive plant species …
