Prioritizing Indigenous Participation And Compensation In Research, Amanda Sabin Feb 2024

Prioritizing Indigenous Participation And Compensation In Research, Amanda Sabin

Journal of Critical Global Issues

Throughout history, the dynamic between colonial entities and indigenous groups has been characterized by exploitation and power imbalance. Indigenous knowledge has the potential to positively impact the world, through medicinal breakthroughs, radical approaches to sustainability, cultural heritage, systems of learning and adaptation, and more. Particularly in the context of research, fields like anthropology, botany and pharmacology serve to benefit from indigenous knowledge, but these interactions cannot continue to be based on extraction at the cost of indigenous communities. This work will discuss the future of relationships between researchers and indigenous communities; how this power dynamic must be transformed into an …


Technological Bottlenecks And Innovative Developments For Rubber Tree Breeding In China, Yongshuai Sun, Weimin Tian, Deli Zhai, Yongping Yang Jan 2024

Technological Bottlenecks And Innovative Developments For Rubber Tree Breeding In China, Yongshuai Sun, Weimin Tian, Deli Zhai, Yongping Yang

Bulletin of Chinese Academy of Sciences (Chinese Version)

Superior varieties of rubber trees are crucial elements in achieving stable production and supply of natural rubber. In China, rubber tree planting areas are situated at the northern edga of the world’s tropical zone and thus belong to non-traditional rubber tree planting areas with climatic conditions inferior to the traditional ones in Southeast Asia. The planted rubber trees are frequently damaged by low temperatures and diseases. Therefore, an urgent need in natural rubber production is to develop varieties with highyield potential and strong stress-tolerance. The scarcity of such varieties is mainly ascribed to the highly heterozygous genome, a long juvenile …


Nine-Step Approach Of Smart Agricultural Helps Grain Production Reduce Costs, Increase Yield And Efficiency, Shuqin Gao, Zhaomin Hu, Hongsheng Wang, Xiaobo Zhang, Yucheng Zhang Jan 2024

Nine-Step Approach Of Smart Agricultural Helps Grain Production Reduce Costs, Increase Yield And Efficiency, Shuqin Gao, Zhaomin Hu, Hongsheng Wang, Xiaobo Zhang, Yucheng Zhang

Bulletin of Chinese Academy of Sciences (Chinese Version)

Food security is a top priority in national governance. Since 1949, high-standard farmland construction, agricultural mechanization development, and agricultural technology promotion have all contributed to the grain production. To ensure grain security, China has drawn a “red line” of 1.8 billion mu (about 120 million hectares) as the official minimum of arable land. At the same time, increasing the investment of capital goods such as fertilizer and pesticides can no longer produce more food. Due to the extensive farming method in the past, the continuous increase in total grain output becomes difficult in the future. With the rapid development of …


Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia Dec 2023

Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia

Journal of Nonprofit Innovation

Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

Aversion Properties Of Retrorsine, Retrorsine Nitrogen Oxide And Frosted Senecio Latifolius, Leendert D. Snyman Dec 2023

Aversion Properties Of Retrorsine, Retrorsine Nitrogen Oxide And Frosted Senecio Latifolius, Leendert D. Snyman

Poisonous Plant Research (PPR)

Two pilot trials, investigating the aversive properties of retrorsine and retrorsine nitrogen oxide and that of frosted Senecio latifolius, were executed. Retrorsine and retrorsine-NO (the toxic principles of Senecio retrorsus), unlke sceleratine-NO (the toxic principle of another hepatotoxic pyrrolizidine alkaloid containing plant, namely S. latifolius), were not capable of establishing aversion when given to a sheep. Frosted S. latifolius given to a sheep also did not induce aversion. However, a sheep averted to S. latifolius (non-frosted) refused eating frosted S. latifolius.


Sceleratin Nitrogen Oxide As Aversive Agent In Conditioning Livestock To Avoid Senecio Latifolius, Leendert D. Snyman Dec 2023

Sceleratin Nitrogen Oxide As Aversive Agent In Conditioning Livestock To Avoid Senecio Latifolius, Leendert D. Snyman

Poisonous Plant Research (PPR)

Sceleratine nitrogen oxide, when administered together with a dichloromethane extract of Senecio latifolius, successfully conditioned cattle and sheep to avoid milled freeze dried S. latifolius mixed with maize meal. This treatment was effectively applied in conditioning steers to refuse eating S. latifolius grown in pots.


Isolation Of The Toxic Principle Of Senecio Latifolius By Means Of The Sensory Receptors Of Sheep, Leendert D. Snyman Dec 2023

Isolation Of The Toxic Principle Of Senecio Latifolius By Means Of The Sensory Receptors Of Sheep, Leendert D. Snyman

Poisonous Plant Research (PPR)

The aversive substance of Senecio latifolius was isolated by means of the sensory receptors of sheep averted to S. latifolius. Chemical fractions refused due to the presence of the aversive substance sensed by the sheep were fractionated until a purified substance had been isolated. Nuclear magnetic resonance (NMR) analysis of the purified substance showed it to be sceleratine nitrogen oxide, the toxic principle of S. latifolius.

Animal Communication And Sentience, Catia Correia-Caeiro, Katja Liebal Jun 2023

Animal Communication And Sentience, Catia Correia-Caeiro, Katja Liebal

Animal Sentience

Segundo-Ortin & Calvo (S&C) argue for sentience in plants on the basis of several studies of what they describe as "cognitive abilities" in plants. As other commentaries (e.g., Brooks Pribac, 2023; Damasio & Damasio, 2023; ten Cate, 2023) have pointed out, however, there is some misuse of several concepts, and a lack of evidence for sentience. We try to clarify three questions in S&C’s discussion: (1) How is communication defined and conceptualised in animal research? (2) Is plant communication comparable to animal communication? (3) Is communication (or the process we see in plants) a good basis for inferring sentience in …


A Most Surprising Fern: Serendipity And Browsing In Botanical Search, Douglas Tuers May 2023

A Most Surprising Fern: Serendipity And Browsing In Botanical Search, Douglas Tuers

Journal of the South Carolina Academy of Science

This article is a case study of botanical field work in the eastern United States in the early twentieth century. These cases will be analyzed as instances of browsing and serendipity. Browsing and serendipity have a rich literature in information science and this article will draw on this literature in order to better understand serendipity in botany. This article will show how botanical localities support browsing and serendipity for the botanists who search them. This article will also show how botanical institutions and botanists interface with localities in order to further support browsing and serendipity. As a whole this article …


Associative Learning: Unmet Criterion For Plant Sentience, Luigi Baciadonna, Catherine Macri, Martin Giurfa May 2023

Associative Learning: Unmet Criterion For Plant Sentience, Luigi Baciadonna, Catherine Macri, Martin Giurfa

Animal Sentience

In a thought-provoking target article, Segundo-Ortin & Calvo (S&C) discuss the possibility that plants are sentient, focusing on a series of capacities normally attributed only to human and nonhuman animals. S&C propose learning as a marker for sentience. We review studies reporting associative learning in plants and find that they either lack essential controls or fail to produce replicable results. The capacity to learn has not yet been demonstrated in plants, so it cannot be used to support the hypothesis that plants are sentient. Further studies are needed. But agnosticism about sentience should not deter us from investigating unexpected new …

Plant Sentience: The Burden Of Proof, Jon Mallatt, David G. Robinson, Michael R. Blatt, Andreas Draguhn, Lincoln Taiz Apr 2023

Plant Sentience: The Burden Of Proof, Jon Mallatt, David G. Robinson, Michael R. Blatt, Andreas Draguhn, Lincoln Taiz

Animal Sentience

Segundo-Ortin & Calvo’s (2023) target article takes a less speculative and more evidence-based approach to plant sentience than did previous works promoting that idea. However, it retains many of the idea’s longstanding difficulties such as starting from a false dichotomy (plants must be either hardwired or sentient), not accepting the full burden of proof for an extraordinary claim, confusingly redefining accepted cognitive terms, implying cell consciousness, not adopting the most parsimonious explanations for plant behaviors, and downplaying all the counterevidence. We advise rectifying these problems before plant sentience can become a full-fledged scientific domain.


Plant Sentience: A Hypothesis Based On Shaky Premises, Carel Ten Cate Apr 2023

Plant Sentience: A Hypothesis Based On Shaky Premises, Carel Ten Cate

Animal Sentience

Plants may produce fascinating behavioural phenomena for which the label ‘cognitive process’ may be applicable, at least by some definitions. Segundo-Ortin & Calvo (2023) base their hypothesis that plants might be sentient on the premise of demonstrated presence of cognitive complexity. However, the way phenomena are ascribed, and how the term ‘cognitive’ is used by Segundo-Ortin & Calvo, deviates from the common practice in studies of animal cognition, implying greater complexity than seems justified. It thus provides a questionable basis for attributing sentience to plants.


Plant Sentience: "Feeling" Or Biological Automatism?, Andrea Mastinu Apr 2023

Plant Sentience: "Feeling" Or Biological Automatism?, Andrea Mastinu

Animal Sentience

Sentience refers to the ability of an organism to have subjective experiences such as sensations, emotions and awareness. Whereas some animals, including humans, are widely recognized as sentient, the question of whether plants are sentient is still debated among scientists, philosophers, and ethicists. Over the past 20 years, many scientists such as Trewavas, Baluška, Mancuso, Gagliano, and Calvo have reported interesting discussions about memory, behavior, communication, and intelligence in plants. However, the reported conclusions have not convinced the entire scientific community. In this commentary, I would like to focus on two critical aspects related to sentience: cognition and emotion

Industrialization Of Tall Wheatgrass For Construction Of “Coastal Grass Belt”, Hongwei Li, Qi Zheng, Jianlin Wang, Hongyong Sun, Kexin Zhang, Hongman Fang, Xuerong Xing, Weicai Yang, Xiaofeng Cao, Xiaojing Liu, Haichun Jing, Kang Chong, Zhensheng Li

Bulletin of Chinese Academy of Sciences (Chinese Version)

Tall wheatgrass (Elytrigia elongata) is a perennial cool-season bunchgrass with high productivity and tolerance to salt and alkali, waterlogging, and drought. Since first introduced into China in 1950s, tall wheatgrass has long been used as a wild parent for distant hybridization with wheat (Triticum aestivum). During 1980s─1990s, a few tall wheatgrass varieties were introduced to China as forage grass, nonetheless, currently they are still not widely cultivated and no variety was certificated. In 2020, Zhensheng Li put forward a proposal to construct “Coastal Grass Belt” on saline and alkaline soils in the Circum-Bohai sea region, which provides an opportunity for …

Whichever side of the debate one chooses, plant sentience is a fertile research area that challenges received views and assumptions, generates novel insights, and suggests new ways that felt states might arise. My commentary discusses methodological and philosophical implications.


From Animal To Plant Sentience: Is There Credible Evidence?, Leonard Dung Apr 2023

From Animal To Plant Sentience: Is There Credible Evidence?, Leonard Dung

Animal Sentience

Segundo-Ortin & Calvo argue that plants have a surprisingly varied and complex behavioral repertoire. Which of these behavioral capacities are credible indicators of sentience? If we use the standards of evidence common in discussions of animal sentience, the behavioral capacities reviewed are insufficient evidence of sentience. Even if some putative indicators of animal sentience are present in plants, it is not clear whether what we should conclude is that plants are sentient or that those indicators are inadequate.


Plants Lack The Functional Neurotransmitters And Signaling Pathways Required For Sentience In Animals, David G. Robinson, Michael R. Blatt, Andreas Draguhn, Lincoln Taiz, Jon Mallatt Apr 2023

Plants Lack The Functional Neurotransmitters And Signaling Pathways Required For Sentience In Animals, David G. Robinson, Michael R. Blatt, Andreas Draguhn, Lincoln Taiz, Jon Mallatt

Animal Sentience

We cannot agree with Segundo-Ortin and Calvo that plants are sentient organisms. We have critically examined several aspects of their target article, and find their claims are not supported by the published evidence. We address these claims in sections on whether plants have a ‘neurobiology’ analogous to that of animal nervous systems, including neurotransmitters and synaptic receptors that respond to anesthetics; and whether plant signaling resembles neural transmission. For the latter, we especially consider the unique way plants signal their responses to wounding. Although the plant vascular system has been compared to the animal nervous system, animal blood vessels would …


Plants Detect And Adapt, But Do Not Feel, Paul C. Struik Apr 2023

Plants Detect And Adapt, But Do Not Feel, Paul C. Struik

Animal Sentience

Plant sentience is a hot topic in scientific and popular media. There are moral reasons to respect both the service of plants to humanity and their natural integrity as creatures playing their own significant role in a complex ecosystem. However, to infer that plants have certain cognitive capacities that are present also in certain human and nonhuman animals calls for scientific rigor beyond mere analogy. The unique capacities of plants identified by Segundo-Ortin & Calvo are not necessarily linked to sentience. Nor is it likely that sentience is an evolutionary trait that is present to some extent in all living …

Enhancement Of Coastal Blue Carbon: Concepts, Techniques, And Future Suggestions, Guangxuan Han, Weimin Song, Yuan Li, Leilei Xiao, Mingliang Zhao, Xiaojing Chu, Baohua Xie

Bulletin of Chinese Academy of Sciences (Chinese Version)

The blue carbon function and carbon sequestration potential of coastal ecosystems, such as salt marshes, mangroves and seagrass beds, have emerged as one of the long-term solutions to mitigate global climate change. However, the blue carbon sequestration technology has been neglected in most ecological protection and restoration projects of coastal ecosystems. Besides, in the process of project implementation and management, the dynamic monitoring and systematic evaluation of carbon sink are imperfect. This study proposes the concept of enhancement of coastal blue carbon, focusing on four key technologies of soil carbon emission reduction technology, plant carbon sequestration technology, soil microbial carbon …


Insentient “Cognition”?, Stevan Harnad Mar 2023

Insentient “Cognition”?, Stevan Harnad

Animal Sentience

A sentient state is a state that it feels like something to be in. Cows have them, cars don’t. Cognitive capacities are a subset of behavioral capacities. Not all behavioral capacities are cognitive (but the distinction is fuzzy). Might the difference have something to do with whether the behaver is sentient?

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Wastewater-recovered phosphorus (P), in the form of the mineral struvite (MgNH4PO4∙6H2O), may provide a sustainable alternative to decreasing rock-phosphate reserves. Struvite can be generated via precipitation methods, potentially reducing the amount of P runoff to aquatic ecosystems. The objective of this greenhouse tub study was to evaluate the effects of chemically and electrochemically precipitated struvite (CPST and ECST, respectively) on aboveground plant response in a hybrid rice cultivar grown using furrow-irrigation compared to other common fertilizer-P sources [i.e., triple super phosphate (TSP) and diammonium phosphate (DAP)] using three replications of fertilizer treatment in a P-deficient silt loam (Typic Glossaqualfs). Aboveground …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Heat stress (HS) is a growing concern in broiler production. Little is known regarding the effect of HS on immune function. To examine the effects of HS on innate immunity, the local- and systemic-inflammatory responses to lipopolysaccharide (LPS) were examined in Cobb 500 male broiler chicks reared under thermoneutral (TN) or cyclic HS conditions. Beginning at four days of age, HS birds were subjected to 35 °C from 8:00 a.m. to 10:00 p.m. and TN temperatures from 10:00 p.m. to 8:00 a.m. At 37 days of age, four groups of broilers were formed: LPS-TN (8 broilers), phosphate-buffered saline (PBS)-TN (4 …
