Effects Of Forage Chicory (Cichorium Intybus) On Farmed Deer Growth And Internal Parasitism, S. O. Hoskin, P. R. Wilson, W. E. Pomroy, T. N. Barry Apr 2023

Effects Of Forage Chicory (Cichorium Intybus) On Farmed Deer Growth And Internal Parasitism, S. O. Hoskin, P. R. Wilson, W. E. Pomroy, T. N. Barry

IGC Proceedings (1977-2023)

Internal parasitism (particularly lungworm - Dictyocaulus sp) significantly limits post-weaning growth of deer. Endoparasite control using anthelmintics may be unsustainable, due to the increasing risk of anthelmintic resistance and the risk or perception of chemical residues in animal products. Chicory has a high feeding value and contains sesquiterpene lactones and low levels of condensed tannins, both with anti-parasitic activity (Molan et al., 2003). Grazing chicory during autumn may reduce the requirement for anthelmintic treatment of young deer compared with grazing ryegrass-based pasture (Hoskin et al., 1999). The objective of this study was to investigate the effect of withholding …

We studied pollination of this species during the summers of 2019–2021 at multiple locations on Pikes Peak, Colorado. We conducted a total of 899 min of pollinator surveys, identifying all floral visitors during this time period. We then examined floral visitors for the presence of T. jamesii pollen to …


The Characterization Of Selected Α- And Β-Carbonic Anhydrases Of Arabidopsis Thaliana, Hiruni Weerasooriya Apr 2023

The Characterization Of Selected Α- And Β-Carbonic Anhydrases Of Arabidopsis Thaliana, Hiruni Weerasooriya

LSU Doctoral Dissertations

Carbonic anhydrases (CAs) are zinc-metalloenzymes that interconvert two inorganic carbon (Ci) species, CO2 and HCO3-. In Arabidopsis thaliana, there are eight αCA genes, six βCA genes, three γCA genes, and two γCA-like genes. The majority of CA research in plants has focused on finding a link between CA activity and photosynthesis rates. Since the CA genes are expressed in different plant tissues and multiple CA isoforms are distributed among various organelles of the plant cell, I hypothesize that CAs facilitate CO2 diffusion among cell compartments and maintain Ci pools for carbon-requiring reactions by interconverting …

Stress: An Adaptive Problem Common To Plant And Animal Science, Özlem Yilmaz Apr 2023

Stress: An Adaptive Problem Common To Plant And Animal Science, Özlem Yilmaz

Animal Sentience

It is very hard to determine whether plants have “felt states,” but they do have specific states, such as stress, that depend on sensory input from their environment. Plants do not have neurons or brains, but they do have xylem and phloem, as well as many signalling molecules that are dynamically distributed in their bodies, enabling them to produce systemic responses to environmental stimuli. One common topic in plant and animal science that may or may not prove to involve sentience but that does involve the same molecules is stress.

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 …
