Complex Floral Behavior Of An Angiosperm Family, Tilo Henning, Moritz Mittelbach
Complex Floral Behavior Of An Angiosperm Family, Tilo Henning, Moritz Mittelbach
Animal Sentience
Segundo-Ortin & Calvo provide a comprehensive overview of the many aspects of plant behavior examined to date. In our view, multiple lines of evidence make it difficult to deny plant sentience. We add further evidence to support the conclusion that plants are sentient organisms. As in animals, the behavior of plants can be seen and studied as an evolutionary trait, subject to and a consequence of increasing complexity in the interactions of plants with their environment. Our example is the evolution of floral behavior in Loasaceae, where complex patterns of stamen movement have co-evolved in interaction with specialized pollinators.

Effects Of Nonnative Plants On Space-Use In Eastern Box Turtles, Emily Ilene Crago
Effects Of Nonnative Plants On Space-Use In Eastern Box Turtles, Emily Ilene Crago
Graduate Theses
Introduction of nonnative plants outside their natural range has caused widespread reduction in the abundance and diversity of native plant species. Nonnative plants typically form dense, often monotypic, thickets that affect the ability of animals to find food, reproduce, avoid predation risk, and thermoregulate. By doing so, nonnative plants have the potential to displace resident animals from areas otherwise suitable as animal habitat. However, limited studies have investigated whether resident animals avoid areas dominated by nonnative plants. This study investigated impacts of nonnative plants on eastern box turtles (Terrapene carolina carolina), a species that has been declining throughout their range. …
Plant Sentience: A Hypothesis Based On Shaky Premises, Carel Ten Cate
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.

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.
Insentient “Cognition”?, Stevan Harnad
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?
