Neurogenesis in the central nervous system of the Nile crocodile (Crocodylus niloticus) throughout ontogenesisNgwenya, Ayanda January 2015 (has links)
The body and central nervous system of the Nile crocodile (Crocodylus niloticus) is
known to grow continuously, even past sexual maturity. Previous studies on crocodilians show a
gradual decrease in the rate of growth of the brain as individuals mature; however, the data on
brain growth are limited and there are no data on growth rates of the spinal cord and retina. The
current thesis provides a description of the growth rates of the brain, spinal cord and eye (ocular
volume) of 70 juvenile and sub-adult Nile crocodiles ranging between 92 g and 90 kg in mass.
Body growth in the crocodiles is accompanied by growth of all central nervous system structures
(brain, spinal cord and eye), although growth occurs at different rates, with the spinal cord being
the fastest growing structure, followed by the eye and the brain. The neurogenic regions (areas to
which new neurons are continuously added) of the brain were revealed using doublecortin
immunohistochemistry. Labelled cells were observed in all the regions of the telencephalon
(including the cortical mantle, dorsal ventricular ridge, striatum, septal nuclei and the olfactory
bulbs) as well as the molecular and granular layers of the cerebellar cortex, but not in the
diencephalon or brainstem.

"Swamp Thing: Alligators, Symbolism, and the Meaning of Animals in the American SouthDrake, Nathan 01 May 2020 (has links)
Humans form lasting and unique relationships with the natural world and, by extension, the organisms and animals who have for millennia carved out niche environments. Scholars and general observers agree—at least in principle—that human beings have actively shaped (for better and for worse) the habitats, behaviors, and population of the Earth’s creatures. In turn, those spaces and animals have influenced not only how humans think of the natural world, but also of humanity itself. Animals, in other words, help humans understand themselves.1 This dissertation is a history of the American Alligator. A study of human interactions with alligators can reveal not only how humans viewed the animal, but also how they created, recreated, and utilized those representations to meet their own ends. Much of what humans attached to alligators—either positive, negative, or oscillating between—were the results of an internal process of dialogue, culture, and human psychology. In simpler terms, this research investigates how human beings understand themselves and how a particular species fits within human understandings of the “natural” world.

Patterns in alligatorine evolutionMiller-Camp, Jessica 01 December 2016 (has links)
Alligatorines are a diverse clade of crocodylians whose history spans the entire Cenozoic. They are suited to answer a variety of questions with far‐reaching impacts due to their physiology and preservation potential, and have been the subject of several phylogenetic, biogeographic, and diversity analyses. However, prior phylogenetic analyses had poor resolution and several putative alligatorines have never been included, while other analyses would be more informative and accurate if viewed through the context of evolutionary history. Here, I analyze the phylogenetics, taxonomy, biogeography, ecomorphology, and diversity dynamics of alligatorines. An almost fully resolved phylogenetic hypothesis returns two major clades within Alligatorinae and includes several putative alligatorines not previously analyzed. The clade originated in North America and dispersed to Europe and Asia three to five times via at least three different corridors at high latitudes when climate—and potentially salinity—were favorable, likely including the recently discovered subaerial Lomonosov Ridge. The modern American alligator is a dietary generalist, but evolved from a durophagous specialist, contrary to the intuitive reasoning of the “Law of the Unspecialized”. It was able to do so by entering the generalist niche vacated by basal crocodyloids following their extirpation from mid‐latitude North America. Alligatorine diversity only weakly tracks climate change and does not track the rock record excepting swampy environments. Alligatorine diversity correlates with climate change. Climate change correlates with rocks, though in a more complicated pattern. Some diversity metrics correlate with some aspects of the rock record, but predominantly do not. There is more support for the common‐cause hypothesis than for rock record bias driving apparent alligatorine diversity. Overall, alligator evolution exhibits a pattern of being more diverse taxonomically and morphologically when the climate is warmer, and dispersing during the warmest and wettest of those times.
