Characterization Of Antimicrobial Properties Of Excrement And Functional Microbiome Of Black Vultures (Coragyps Atratus), Bridgette Gray
Theses
Black vultures, Coragyps atratus, are obligate scavenging birds that consume and dispose of decaying carcasses and carrion. They fulfill a key ecological niche in the environments in which they live. It has been observed that these vultures sometimes excrete bodily waste onto their legs. This adaptive behavior could help aid them in controlling bacteria and other microbes they encounter while stepping into a carcass to eat. This study directly examined the antimicrobial properties of the excrement of black vultures across various bacterial species utilizing a zone of inhibition test and a nematode species utilizing a survival assay. The black vulture …

We present molecular data on Isometrus maculatus (DeGeer, 1778) for the first time from India, Japan, and Taiwan based on the COI gene and justify the cosmopolitan nature of this species. We also address the first population of I. maculatus found in Teliamura, Tripura, India and give its detailed description and comparison with the rest of the Isometrus species from India. Furthermore, we discuss the justification for considering Sri Lanka as the true home of I. maculatus.

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 …

Five species of the genus Heterometrus Ehrenberg, 1828 are currently confirmed from Thailand and revised, with their respective distribution range in this country updated. Heterometrus laevigatus (Thorell, 1876) is considered a nomen dubium, while its two previous junior synonyms, H. cimrmani Kovařík, 2004, stat. rev. and H. minotaurus Plíšková et al., 2016, stat. rev. are revalidated and redescribed based on the examination of topotypes. Females of H. minotaurus Plíšková et. al., 2016, stat. rev. were also collected and examined, and their characters are herein described with a special attention to sexual dimorphism. Furthermore, some populations previously regarded as H. …

Theropithecus oswaldi darti, as currently understood, is the oldest Theropithecus taxon in the fossil record and the earliest subspecies in the Theropithecus oswaldi lineage. Theropithecus oswaldi darti is typified at the site of Makapansgat in South Africa, and a similar form (T. o. cf. darti) is usually recognized at Hadar, Dikika, some Middle Awash localities, and Woranso-Mille in Ethiopia. This taxon is also tentatively believed to occur in Kenya at Kanam and Koobi Fora and in Member C of the Shungura Formation in Ethiopia. While there is a general consensus that the East African ‘darti’ specimens are …

Statistical And Biological Analyses Of Acoustic Signals In Estrildid Finches, Moises Rivera
Dissertations, Theses, and Capstone Projects
Acoustic communication is a process that involves auditory perception and signal processing. Discrimination and recognition further require cognitive processes and supporting mechanisms in order to successfully identify and appropriately respond to signal senders. Although acoustic communication is common across birds, classical research has largely disregarded the perceptual abilities of perinatal altricial taxa. Chapter 1 reviews the literature of perinatal acoustic stimulation in birds, highlighting the disproportionate focus on precocial birds (e.g., chickens, ducks, quails). The long-held belief that altricial birds were incapable of acoustic perception in ovo was only recently overturned, as researchers began to find behavioral and physiological evidence …

Fluidity And Inconstancy: Australian Bush Tomatoes As An Exemplar Of Non-Normative Sex Expression, Christopher T. Martine
Faculty Journal Articles
Solanum, a genus of ~1500 global species, is one of the more interesting plant groups in which to study reproductive biology and ecology. Overwhelmingly, species in this group express full cosexuality, where individual plants have flowers containing both fully-functioning “male” (staminate) and “female” (carpellate) organs. However, there have been multiple and widespread evolutionary transitions within the genus to non-normative variations on this ancestral condition. Australian bush tomatoes (ca. 40 species) are especially diverse in this regard, with uncommon variation and combinations of unisexuality and cosexuality -- including, most notably, two sexual systems known as dioecy (unisexual male or female …

Animal Sentience
In a thought-provoking target article, Segundo-Ortin & Calvo (S&C) discuss the possibility that plants are sentient, focusing on a series of capacities normally attributed only to human and nonhuman animals. S&C propose learning as a marker for sentience. We review studies reporting associative learning in plants and find that they either lack essential controls or fail to produce replicable results. The capacity to learn has not yet been demonstrated in plants, so it cannot be used to support the hypothesis that plants are sentient. Further studies are needed. But agnosticism about sentience should not deter us from investigating unexpected new …

Disentangling Sentience From Developmental Plasticity, Jonathan Birch
Animal Sentience
Plants, like animals, display remarkable developmental plasticity, inviting the metaphorical use of terms like “decision” and “choice”. In the animal case, this is not taken to be evidence of sentience, because sentience is a complex product of development, not something that guides it. We should apply the same standards when evaluating the evidence in plants. It is hard to overstate the contrast with the case of invertebrates such as octopuses, where pain markers that were originally developed for use in mammals have been clearly demonstrated and plausible neural substrates for sentience have been identified.

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.

Analysis Of Gene Evolution In The Long-Lived Heliconius Butterfly Genus, Leann Ward
Theses and Dissertations
The butterfly genus Heliconius has an unusually long lifespan (six to eight months compared to only several weeks) and the unique ability to feed on pollen. The additional amino acids provided by a pollen diet seem intrinsically tied to longer lifespan in Heliconius. Because of these traits, Heliconius may be a valuable model species for future aging studies. As a preliminary analysis, we investigated differences in gene evolution between Heliconius and seven short-lived butterflies. We observed that the Heliconius genes had significant differences in evolutionary rates, in the direction of selection, and in the amounts of site-specific positive selection compared …

Causes And Consequences Of Lasr Mutant Selection In Pseudomonas Aeruginosa Populations, Dallas L. Mould
Dartmouth College Ph.D Dissertations
Change is the only constant in life, and these changes, though random in nature, can have consequences. Quorum sensing is heterogeneous in phenotype and prone to negative selection. In P. aeruginosa, the regulator LasR is frequently non-functional in phylogenetically diverse isolates. Through repeated experimental evolution and mathematical modeling, we show that differences in growth enable lasR mutant evolutionary success and this requires a system enabling metabolic choices, known as carbon catabolite repression (or catabolite repression). The differences in catabolite repression between wild type and lasR mutants enable altered metabolite preferences, and the resulting differences in metabolic states enable intraspecies …

Emancipations: A Journal of Critical Social Analysis
In 1902, the anarchist Peter Kropotkin published Mutual Aid in which he promoted a radical perspective on evolution in which cooperation, as well as selfishness, drive the form, diversification and organization of life on earth. Despite initial recognition, Kropotkin’s contributions have been largely forgotten, even as modern evolutionary theory has recognized the central role of cooperation. In Mutual Aid: the other law of the jungle, Pablo Servigne and Gauthier Chappelle restore Kropotkin’s insights to their rightful place as foundational for our understanding of evolution. They further seek to overturn the pernicious misconception of the 20th century, that nature is …

How Phylogeny And Arboreality Affect Pelvic Girdle Anatomy Of Chameleons, Dakota J. John
Honors Thesis
Morphological adaptations have allowed animals to inhabit different landscapes such as mountains, forests, plains, etc. These adaptations have increase in prevalence through natural selection processes in all species which allow favorable traits to be passed to offspring. Chameleons have evolved a plethora of adaptations that have allowed them to persist in different niches. One anatomical feature of chameleons that has not been well studied is the pelvic girdle. The pelvic girdle bridges the axial and appendicular skeletons in animals, so the size, shape, and orientation of the girdle is important to how the animal functions in its environment. The pelvic …
