Invertebrate Cognition, Sentience And Biology, Georges Chapouthier 2020 CNRS, Paris

Invertebrate Cognition, Sentience And Biology, Georges Chapouthier

Animal Sentience

All animal species have adapted for survival and no species is superior overall. For cognitive capacities and sentience, invertebrates such as the octopus, although quite unlike vertebrates, can achieve similar performance levels. So can other invertebrates with small brains; hence they too, as sentient beings, deserve moral consideration from humans. How are we to identify these species? Only though a detailed analysis of their behavior. The decision, which is a moral judgment, depends on biological knowledge that still needs to be acquired.


Convergent Evolution Of Sentience?, Culum Brown Prof. 2020 Macquarie University

Convergent Evolution Of Sentience?, Culum Brown Prof.

Animal Sentience

Mikhalevich & Powell make a compelling case that some invertebrates may be sentient and that our moral obligations in the context of welfare should hence extend to them. Although the case is similar to that made for fishes, there is one obvious difference in that examples of invertebrate sentience probably arose independently from vertebrate sentience. We have unequivocal proof that complex cognition arose multiple times over evolutionary history. Given that cognition is our best tool for indirectly quantifying sentience, it seems highly likely that this multiple polygenesis may also have occurred for sentience. In acknowledging this, we must accept that the ...


The Use Of The Heter-Lp Algorithm To Reposition Antibiotics For Managing E. Coli Mastitis In Dairy Cattle, Somayeh Sharifi, Maryam Lotfi Shahreza, Abbas Pakdel, James M. Reecy, Nasser Ghadiri, Hadi Atashi, Mahmoud Motamedi, Esmaeil Ebrahimie 2020 Isfahan University of Technology

The Use Of The Heter-Lp Algorithm To Reposition Antibiotics For Managing E. Coli Mastitis In Dairy Cattle, Somayeh Sharifi, Maryam Lotfi Shahreza, Abbas Pakdel, James M. Reecy, Nasser Ghadiri, Hadi Atashi, Mahmoud Motamedi, Esmaeil Ebrahimie

Animal Science Publications

Mastitis, a disease with high incidence worldwide, is the most prevalent and costly disease in the dairy industry. Environmental mastitis pathogens, such as Escherichia coli (E. coli), are major etiological agents of bovine mastitis in well-managed dairy farms. However, there is still a need to develop more efficient, safe, and economical treatments for mastitis. In the current research, Heter-LP, a new system biology-based method of drug repositioning, was applied to potentially identify novel therapeutic avenues for the treatment of E. coli mastitis. On-line data repositories relevant to known diseases, drugs, and gene targets along with other specialized biological information for ...


Notes On The Diet And Reproduction Of The Bark Scorpion Centruroides Gracilis (Scorpiones: Buthidae) On Utila Island, Honduras, Anna M. Davison, Tom W. Brown, Cristina Arrivillaga 2020 Marshall University

Notes On The Diet And Reproduction Of The Bark Scorpion Centruroides Gracilis (Scorpiones: Buthidae) On Utila Island, Honduras, Anna M. Davison, Tom W. Brown, Cristina Arrivillaga

Euscorpius

The brown bark scorpion Centruroides gracilis (Latreille, 1804) (Buthidae) is an abundant and widespread species, however, fairly little is known about its ecology and natural history. We include several observations from Utila Island, Honduras, that expand on the known literature regarding the diet and reproductive behavior of C. gracilis. We report several prey items for this opportunistic species, which include invertebrates such as spiders (including tarantulas), centipedes, katydids, and crickets; as well as a case of cannibalism between two adult females C. gracilis. We suggest that such cannibalism may be driven by high population densities and/or strong intraspecific competition ...

Minds, Morality And Midgies, Brian Key, Deborah Brown

Animal Sentience

Mikhalevich & Powell argue that the exclusion of the vast majority of arthropods from moral standing is unwarranted, particularly given the purported evidence for cognition and sentience in these organisms. The implied association between consciousness and moral standing is questionable and their assumption that rich forms of cognition and flexible behavior are dependent on phenomenal consciousness needs to be reconsidered in light of current neuroscientific evidence. We conclude by proposing a neural algorithmic approach for deciphering whether organisms are capable of subjective experience.


Host Immunity And The Colon Microbiota Of Mice Infected With Citrobacter Rodentium Are Beneficially Modulated By Lipid-Soluble Extract From Late-Cutting Alfalfa In The Early Stages Of Infection, Krysten Fries-Craft, Justin M. Anast, Stephan Schmitz-Esser, Elizabeth A. Bobeck 2020 Iowa State University

Host Immunity And The Colon Microbiota Of Mice Infected With Citrobacter Rodentium Are Beneficially Modulated By Lipid-Soluble Extract From Late-Cutting Alfalfa In The Early Stages Of Infection, Krysten Fries-Craft, Justin M. Anast, Stephan Schmitz-Esser, Elizabeth A. Bobeck

Animal Science Publications

Alfalfa is a forage legume commonly associated with ruminant livestock production that may be a potential source of health-promoting phytochemicals. Anecdotal evidence from producers suggests that later cuttings of alfalfa may be more beneficial to non-ruminants; however, published literature varies greatly in measured outcomes, supplement form, and cutting. The objective of this study was to measure body weight, average daily feed intake, host immunity, and the colon microbiota composition in mice fed hay, aqueous, and chloroform extracts of early (1st) and late (5th) cutting alfalfa before and after challenge with Citrobacter rodentium. Prior to inoculation, alfalfa supplementation did not have ...


Autonomous Recording Units As An Alternative Method For Monitoring Songbirds, Lindsay Clough 2020 University of Massachusetts Amherst

Autonomous Recording Units As An Alternative Method For Monitoring Songbirds, Lindsay Clough

Masters Theses

There is an increasing interest in the use of autonomous recording units as an alternative survey method to point count surveys conducted by human observers; however, questions remain about whether or not these recording units perform similarly to point count surveys and produce valid, comparable results. The use of individual listeners to transcribe the acoustic data collected by autonomous recording units is a common method for the analysis of recorded acoustic data, but potential variability among transcribers raises questions about the standardization of listening protocols to decrease inconsistencies in transcription results.

Autonomous recording units have been used to monitor birds ...

A New Lesser Antillean Scorpion Of The Genus Didymocentrus Kraepelin, 1905 (Scorpiones: Diplocentridae), Rolando Teruel, Karl Questel 2020 Marshall University

A New Lesser Antillean Scorpion Of The Genus Didymocentrus Kraepelin, 1905 (Scorpiones: Diplocentridae), Rolando Teruel, Karl Questel

Euscorpius

A new species of the diplocentrid scorpion of the genus Didymocentrus Kraepelin, 1905 is herein described from the Lesser Antillean island of Martinique. It long remained misidentified as Didymocentrus lesueurii (Gervais, 1844), the only species of this genus inhabiting the adjacent island of Saint Lucia. The direct comparison of adults of both sexes from these two islands revealed solid morphological characters, which warrant their recognition as two different taxa. Each one is endemic from a single major island, where it is widespread even in its satellite islets. This addition raises the known composition of the genus to 12 species, 10 ...

Animal Science Publications

Background There has been an increased interest in nutritional strategies to manipulate the fatty acid profile of pigs. Dietary regimens involving the use of oils that are high in monosaturated fatty acid (MUFA), primarily oleic acid (OA), such as canola oil (CO), as well as in omega (n)-3 polyunsaturated fatty acid (PUFA), which are found in fish oil (FO), have been investigated aiming healthier fatty acid profile cuts, with a higher ratio of n-3 to n-6 fatty acids. Therefore, the effects of including 3% soybean oil (SO), CO, or FO in growing-finishing pig diets vs. feeding a standard commercial ...

Raman Spectroscopy Characterization Extracellular Vesicles From Bovine Placenta And Peripheral Blood Mononuclear Cells, Han Zhang, Ana Caroline Silva, Wei Zhang, Heloisa M. Rutigliano, Anhong Zhou

Animal, Dairy, and Veterinary Science Faculty Publications

Placenta-derived extracellular vesicles (EVs) are involved in communication between the placenta and maternal immune cells possibly leading to a modulation of maternal T-cell signaling components. The ability to identify EVs in maternal blood may lead to the development of diagnostic and treatment tools for pregnancy complications. The objective of this work was to differentiate EVs from bovine placenta (trophoblast) and peripheral blood mononuclear cells (PBMC) by a label-free, non-invasive Raman spectroscopy technique. Extracellular vesicles were isolated by ultracentrifugation. Dynamic light scattering (DLS) and scanning electron microscopy (SEM) were applied to verify the presence and the size distribution of EVs. Raman ...


Equine Nutrition: Concentrates, Karl Hoopes, Patricia Evans, Scott McKendrick 2020 Utah State University

Equine Nutrition: Concentrates, Karl Hoopes, Patricia Evans, Scott Mckendrick

All Current Publications

Concentrate (grain) should be considered only as supplements to good quality hay. In general, a mature horse does not require the energy provided by concentrate-type feeds (grains/sweet feeds, pelleted feed, etc.) unless the horse is used for more than light work or in production, such as a lactating mare or a breeding stallion. Too many times horses are overfed rather than underfed. This fact sheet will help horse owners understand the digestive process and the general feeding requirements, including different grains and mixed grains, for their horses.

Effects Of Ndf Digestibility On Lactating Jersey Cows: Observed And Modeled Performance, Kirby Krogstad 2020 University of Nebraska - Lincoln

Effects Of Ndf Digestibility On Lactating Jersey Cows: Observed And Modeled Performance, Kirby Krogstad

Theses and Dissertations in Animal Science

Improving the digestibility of fiber and our understanding of how to feed it will optimize the ruminants’ niche in our society, which is to convert human inedible products to high quality protein in the form of meat and milk. Neutral detergent fiber (NDF) digestibility has been studied and modeled for decades, but it is increasingly important as livestock production is scrutinized for resource use and sustainability. Increasing the amount of NDF fed and improving models of NDF digestibility will improve sustainability by increasing the precision at which we feed livestock which results in less nutrient and greenhouse gas (GHG) emissions ...


The Role Of Postnatal Adrenergic Manipulation In The Mediation Of Fetal Programming Adaptions In Growth And Skeletal Muscle Glucose Metabolism That Persist In The Juvenile Iugr-Born Lamb, Rachel L. Gibbs 2020 University of Nebraska - Lincoln

The Role Of Postnatal Adrenergic Manipulation In The Mediation Of Fetal Programming Adaptions In Growth And Skeletal Muscle Glucose Metabolism That Persist In The Juvenile Iugr-Born Lamb, Rachel L. Gibbs

Theses and Dissertations in Animal Science

Our 1st study assessed growth deficits in IUGR juvenile lambs and the benefits of treatment with adrenergic and inflammatory mediators. Growth metrics including bodyweight, rate of gain, and crown-rump length were diminished by placental insufficiency-induced IUGR through 2 mo. of age but were recovered by daily clenbuterol or curcumin supplementation. Body composition metrics indicated by bioelectrical impedance, proximate analysis, and loin size revealed that fat-free lean mass, specific muscle group sizes, and protein-to-fat ratios were reduced in unsupplemented IUGR lambs but recovered to or even past controls in clenbuterol-supplemented lambs. From these findings, we conclude that IUGR impairs postnatal ...
