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 …

Sensing Is A Far Cry From Sentience, Antonio Damasio, Hanna Damasio Apr 2023

Sensing Is A Far Cry From Sentience, Antonio Damasio, Hanna Damasio

Animal Sentience

The hypothesis that plants might be sentient confuses the notion of sentience (or consciousness) with that of sensing. Sentience/consciousness implies feeling, experience, and subjectivity. Sensing does not. Plants can sense/detect and even respond appropriately in the absence of any sentience/consciousness.


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.


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 …

Wetlands In Our Backyard: A Review Of Wetland Types In Virginia State Parks, Kirsten Bauer, Benjamin K. Campbell

Virginia Journal of Science

Wetlands constitute a significant component of Virginia’s natural resources and heritage. Though historically they have been discounted—and often denigrated—the exceptional value of wetlands is currently growing in recognition and appreciation. In addition to the value provided by extracted resources and ecological regulation, wetlands also offer people the opportunity to enrich themselves through cultural, educational, and recreational pursuits. The state parks of Virginia provide access to a variety of ecosystems, including a wide array of wetland types. In this review, we document the diversity of wetlands in Virginia State Parks through a typology that groups wetland systems into the three principal …

Effects Of Elevated Co2 Concentrations And Elevated Temperatures On Isoprene Emissions Of Rhamnus Cathartica (European Buckthorn), Quercus Rubra (Red Oak) And Quercus Michauxii (Swamp Chestnut Oak), Janet G. Núñez

DePaul Discoveries

Tropospheric ozone is a ground-level pollutant and is produced from primary air pollutants like nitrogen oxides and volatile organic compounds (VOCs). While many VOCs are anthropogenic, isoprene is emitted from certain species of plants and reacts with nitrogen oxides to form ozone. Previous studies have found that isoprene can be suppressed by CO2, but such suppression can be reduced under conditions of increased temperature. However, this pattern is not seen in all plants capable of emitting isoprene. The focus of this is study is to determine if similar patterns are present in the invasive tree species of buckthorn …


Fruits Of Nandina Domestica Are (Sometimes) Cyanogenic And (Sometimes) Hazardous To Birds, Scott Zona Apr 2022

Fruits Of Nandina Domestica Are (Sometimes) Cyanogenic And (Sometimes) Hazardous To Birds, Scott Zona

Poisonous Plant Research (PPR)

A 12-month survey of cyanogenesis in the fruits and leaves of Nandina domestica (Berberidaceae) revealed that the leaves are strongly cyanogenic throughout the year, as measured by the Feigl-Anger test. Fruits vary in their cyanogenic potential depending on the degree of ripeness and clone. Green fruits are strongly and rapidly cyanogenic, but most ripe fruits are weakly and slowly cyanogenic. Some fruits tested negative for cyanide. Fruits tend to become less cyanogenic the longer they remain on the plant, so birds feeding on older fruits are at a lower risk of poisoning. More than other frugivores, cedar waxwings (Bombycilla …

Human–Wildlife Interactions

Domestic livestock grazing is the dominant land use on much of the current range inhabited by greater sage-grouse (Centrocercus urophasianus; sage-grouse) in the western United States. Nonnative feral horses (Equus ferus caballus) also inhabit important sage-grouse seasonal habitats. Overabundant feral horse populations and improper grazing by domestic cattle (Bos taurus) can impact the health of sagebrush (Artemisia spp.) and desert shrub rangeland communities and native wildlife. These impacts to sage-grouse can be exacerbated when they affect late brood-rearing habitat, which provide the forbs and arthropods required to fledge broods. Managers require better information …

The Effects Of Ppal-1 In Arabidopsis Gamete Development, Amanda J White, Susana Perez-Martinez, Mark P. Running

The Cardinal Edge

Prenylation is a type of post-translational modification in which a 15- or 20-carbon lipid is added to the carboxyl (C) terminus of the protein. Arabidopsis thaliana contains the PROTEIN PRENYLTRANSFERASE ALPHA SUBUNIT-LIKE (PPAL) gene, which encodes a protein with homology to the α-subunits of the three known prenylation enzymes, PFT, PGGT, and Rab-GGT. We previously identified two mutations in PPAL, one of which is ppal-1, which contains a T-DNA insertion in the fourth intron. We have previously observed that self-fertilizing heterozygous ppal-1 plants produce progeny in which homozygous ppal-1 is underrepresented. This project attempts to ascertain …

Identification Of The Biological Function Of Rab-Ggt Β-Subunits By Reverse Techniques, Briana L. Seibert, Hyun Jin Jung, Mark P. Running

The Cardinal Edge

Abstract

Protein prenylation is a post-translational process where lipids are added to carboxyl end groups of amino acids, which allows proteins to function properly in the eukaryotic cell. The job of prenylation is to target certain proteins to specific membranes and promote desirable protein-protein interactions. In our study we used reverse genetics techniques to investigate the function of protein prenylation in plant development. To discern the function of protein prenylation, we examined the phenotypic changes caused by specific gene disruptions. In this study the model organism Physcomitrella patens (moss) is utilized due to its simple structure, limited quantities of tissues …

Protein prenylation is the addition of a 15 or 20 carbon lipid to a cysteine near carboxyl terminus of target proteins. Prentlyation increases hydrophobicity, which facilitates membrane associations and protein-protein interaction. Protein prenylation is generally conserved among eukaryotes, and mutations in genes that carry out prenylation are lethal in animals and yeast. In plants prenylation mutations are not always lethal, but they do affect development, disease resistance, biofuel production, and drought response, among other processes of …
