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.

A New Monotypic Genus And Species From China, Langxie Feti Gen. Et Sp. N. (Scorpiones: Buthidae), Victoria Tang, Qingquan Jia, Leonhard Liu

Euscorpius

A new monotypic genus, Langxie gen. n., is described from Xizang (Tibet), China. The new genus shares an important morphological character with Afrolychas Kovařík, 2019: absence of external accessory denticles (EADs) along the sixth row of median denticles (MDs) on the pedipalp movable finger. Langxie gen. n. is different from Afrolychas in the following aspects: loss of EAD near the proximally enlarged MD within each row (i. e., loss of all EAD on the movable finger; this also distinguishes the new genus from other related genera in the “(Ananteris + Isometrus)” clade (Štundlová et …

Animal Sentience

I welcome Segundo-Ortin & Calvo’s (2023) call for a rigorous science of plant behavior and physiology. My commentary addresses three points drawn from the literature on animal brains that could help elucidate the possibility of cognition and sentience in plants: (1) the presumed requirement of a centralized brain; (2) centralization of control versus heterarchical organization; and (3) connecting plant research with research on animal nervous systems.

Questions About Sentience Are Not Scientific But Cultural, Yoram Gutfreund

Animal Sentience

Abstract: The findings of complex cognitive-like behaviours in plants are surprising and exciting. However, they do not provide a scientific reason for ascribing sentience to plants. The target article, in trying to provide evidence for sentience in plants, exposes the weakness of the science of animal consciousness in general. In this commentary, I try to explain why the scientific method is incapable of resolving the question of which organisms or systems are sentient.

MANTER: Journal of Parasite Biodiversity

The geographical ranges of many mammals and their associated parasites are dynamic. Comprehensive documentation of these communities over time provides a foundation for interpreting how changing environmental conditions, driven by accelerating climate change, other anthropogenic disturbances, and natural events, may influence host-parasite interactions. Fleas (Order Siphonaptera) are obligate, hematophagous parasites of birds and mammals with medical interest because of their role in transmitting pathogens. From 2016 to 2019, we sampled the small mammal and associated flea communities in El Malpais National Conservation Area (El Malpais) in Cibola County, New Mexico. Among 898 mammalian specimens, 925 fleas representing 29 species were …


Morphological Differences Align With Habitat Partitioning Among Three Species Of Percina (Percidae: Actinopterygii) In The Roanoke River, Virginia, Michael M. Calvert, Steven L. Powers 2023 Roanoke College

Morphological Differences Align With Habitat Partitioning Among Three Species Of Percina (Percidae: Actinopterygii) In The Roanoke River, Virginia, Michael M. Calvert, Steven L. Powers

Southeastern Fishes Council Proceedings

The upper Roanoke River has three species of Percina (P. nevisense, Chainback Darter; P. roanoka, Roanoke Darter; and P. rex, Roanoke Logperch). Resource partitioning appears to be a key component of maintaining diverse fish assemblages with habitat and food partitioning cited as especially important in communities containing members of the same family. Some aspects of the diets of these species have been documented in the literature with only modest differences among them. Microhabitat data for adults of these species have also been published revealing differences in habitat occupied by each with P. roanoka living in the fastest, shallowest …


Increasing Capture Rates Of Grassland Birds Over Thirteen Years Indicates Successful Restoration, Katie Stumpf, Charles Muise 2023 Georgia College & State University

Increasing Capture Rates Of Grassland Birds Over Thirteen Years Indicates Successful Restoration, Katie Stumpf, Charles Muise

Georgia Journal of Science

Grassland bird populations are being lost at an alarming rate due to human modifications to grassland ecosystems. Grassland restoration has been shown to mitigate population declines for many species that use these habitats at some point in their annual cycles. We examined capture rates of adult, breeding, and hatch-year birds at a restored grassland site in the piedmont of central Georgia to determine whether colonization, breeding success, hatching success, and recruitment processes were impacting populations of grassland birds. We banded birds approximately twice per month from January 2009 through December 2021 at Panola Mountain State Park. Restoration efforts started in …

Insentient “Cognition”?, Stevan Harnad 2023 Université du Québec à Montréal & University of Southampton

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?

Non-Aggressive Competition Between Males Of Srilankametrus Yaleensis (Kovařík Et Al., 2019) (Scorpionidae), And Other Types Of Agonistic Behavior Observed In Scorpions, Victoria Tang 2023 Marshall University

Non-Aggressive Competition Between Males Of Srilankametrus Yaleensis (Kovařík Et Al., 2019) (Scorpionidae), And Other Types Of Agonistic Behavior Observed In Scorpions, Victoria Tang

Euscorpius

A peculiar intraspecific agonistic behavior involving a non-aggressive physical combat is reported between the adult males of Srilankametrus yaleensis (Kovařík et al., 2019) (Scorpionidae: Heterometrinae). The adult males were observed to resort to a ritualized and relatively gentle way for strength demonstration. The combat is characterized by lateral spreading of pedipalps, chelicerae-to-chelicerae collision, and entanglement of metasomal segments. This behavior is hereby considered a form of an intrasexual combat defined as the “arm-span competition”. It is hypothesized to be beneficial for solving territorial and/ or sexual competitions while avoiding unnecessary mortality which could pose adverse impact to the natural populations. …

Burmese pythons (Python molurus bivittatus) are native to southeastern Asia, however, there is an established invasive population inhabiting much of southern Florida throughout the Greater Everglades Ecosystem. Pythons have severely impacted native species and ecosystems in Florida and represent one of the most intractable invasive-species management issues across the globe. The difficulty stems from a unique combination of inaccessible habitat and the cryptic and resilient nature of pythons that thrive in the subtropical environment of southern Florida, rendering them extremely challenging to detect. Here we provide a comprehensive review and synthesis of the science relevant to managing invasive …

Methylene Blue Inhibits Cromakalim-Activated K+ Currents In Follicle-Enclosed Oocytes, Dmytro Isaev, Keun-Hang Susan Yang, Georg Petroianu, Dietrich Ernst Lorke, Murat Oz

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The effects of methylene blue (MB) on cromakalim-induced K+ currents were investigated in follicle-enclosed Xenopus oocytes. In concentrations ranging from 3–300 μM, MB inhibited K+ currents (IC50: 22.4 μM) activated by cromakalim, which activates KATP channels. MB inhibited cromakalim-activated K+ currents in a noncompetitive and voltage-independent manner. The respective EC50 and slope values for cromakalim-activation of K+ currents were 194 ± 21 µM and 0.91 for controls, and 206 ± 24 µM and 0.87 in the presence of 30 μM MB. The inhibition of cromakalim-induced K+ currents by MB was not …
