Macrophyte Community Analysis Of The Tennessee-Tombigbee Waterway, The Pearl River, And The Pascagoula River, Samuel A. Schmid, Nicholas J. Engle-Wrye, Gray Turnage
Macrophyte Community Analysis Of The Tennessee-Tombigbee Waterway, The Pearl River, And The Pascagoula River, Samuel A. Schmid, Nicholas J. Engle-Wrye, Gray Turnage
Research Data
The macrophyte Tennessee-Tombigbee Waterway, Pearl River, and Pascagoula River were surveyed using point surveys. Data collected from these surveys were used to determine differences in species composition among macrophyte communities, how latitude affected species richness, and how the presence/absence of introduced species was affected by native richness. Differences in species composition were measured using NMDS, and the latitude-richness and introduced-native relationships were modeled using linear modeling methods. This record includes the data and code used for these analyses.

Arid ecosystems remain under-mapped at actionable scales despite their ecological importance. Decision makers lack reliable, high-resolution habitat maps in drylands to prioritize protection and target restoration. This research integrates spaceborne hyperspectral imaging from the Environmental Mapping and Analysis Program (EnMAP) with deep learning semantic segmentation models to produce an updated level of habitat classification based on the International Union for Conservation of Nature (IUCN) for part of the Imam Turki bin Abdullah Royal Reserve, Saudi Arabia. Using ground control points and the full EnMAP spectral cube without band selection, U-Net and DeepLabV3+ architectures were each implemented with VGG19 and ResNet-101 …
Linking A Seasonal Freshwater Prey Subsidy To The Body Condition Of An Estuarine Consumer In A Subtropical Coastal River, Jordan A. Massie, Ryan J. Rezek, W. Ryan James, Rolando O. Santos, Natasha M. Viadero, Ross E. Boucek, Jennifer S. Rehage
Linking A Seasonal Freshwater Prey Subsidy To The Body Condition Of An Estuarine Consumer In A Subtropical Coastal River, Jordan A. Massie, Ryan J. Rezek, W. Ryan James, Rolando O. Santos, Natasha M. Viadero, Ross E. Boucek, Jennifer S. Rehage
Marine Science
Movements of fishes among habitats often correspond to shifting resource availability and can occur in response to fluctuating freshwater inflows in coastal systems. Seasonal availability of prey can provide resources that increase fitness, yet hydrologic variability can influence the movements of both consumers and prey. Shifts in the timing/magnitude of prey availability driven by climate and water management may lead to a resource mismatch, carrying consequences for growth, survival, and reproduction. Here, we examined how seasonal/interannual variation in prey biomass (sunfishes, Lepomis spp.) affects the body condition of Common Snook (Centropomus undecimalis) in Everglades National Park. Further, we investigated how …

Both Studying And Protecting Octopuses “On Their Own Terms”, Jennifer Jacquet, Janelle Kaz, Becca Franks, Christine Webb
Animal Sentience
Cephalopods – indeed, all animals – “must be seen on their own terms,” with respect for their autonomy and their ecological imperatives. This will provide greater scientific insight along with a more ethical and accurate understanding of minds beyond our own.
Cephalopod Consciousness On “Their Own Terms”: Who Are “They”?, Willa M. Lane, Victor Ajuwon, Nicola S. Clayton
Cephalopod Consciousness On “Their Own Terms”: Who Are “They”?, Willa M. Lane, Victor Ajuwon, Nicola S. Clayton
Animal Sentience
Mather’s call to consider cephalopods’ consciousness “on their own terms” raises the question of the extent to which cephalopods can be considered a homogenous group. While coloeoid cephalopods share traits that strongly distinguish them from other molluscs and invertebrates, they show vast ecological and morphological diversity, with implications for the design of empirical investigations of consciousness. Extending Mather’s argument, we apply Birch et al.’s (2020) five-dimensional model to compare octopus, cuttlefish, squid, and nautilus. This comparison shows that even within a graded rather than categorical framework, putative consciousness profiles depend on which taxa are included in discussions of “cephalopod consciousness.” …
Population Structure Analysis Of Four Basal Higher-Attines Using Bioinformatic Approaches, Gabriel Mcdanield
Population Structure Analysis Of Four Basal Higher-Attines Using Bioinformatic Approaches, Gabriel Mcdanield
Biology Theses
Metapopulations within the family Formicidae are unique among other animals due to the large colonies they build, and the mating strategies required to fertilize a specialized reproductive caste that will often produce young for the life of the colony. One group of ants, the fungus-gardeners (tribe Attini). The population structure of North American non-leafcutting, fungus-gardening ants has been understudied, especially in the southwest of the United States. Additionally, not much is known about their dispersal biology, so the dynamics of dispersal of these species and how they affect population structure is likewise not well known. To shed light on the …
Nepenthes Megastoma (Nepenthaceae), A Micro-Endemic Pitcher Plant From Puerto Princesa Subterranean River National Park, Palawan, Philippines, John Charles A. Altomonte, John Paul R. Collantes, Vernaluz Mangussad, Rene Alfred Anton Bustamante, Alastair S. Robinson
Nepenthes Megastoma (Nepenthaceae), A Micro-Endemic Pitcher Plant From Puerto Princesa Subterranean River National Park, Palawan, Philippines, John Charles A. Altomonte, John Paul R. Collantes, Vernaluz Mangussad, Rene Alfred Anton Bustamante, Alastair S. Robinson
Environmental Science Faculty Publications
Nepenthes megastoma is described and illustrated as a new species from the Puerto Princesa Subterranean River National Park, a UNESCO World Heritage Site in Palawan Philippines. This carnivorous tropical pitcher plant is currently known from just three locations in the Mount Saint Paul karst formation, where it grows on vertical limestone walls. Morphologically, N. megastoma is characterised by its highly branched stems, campanulate pitchers, peltate tendril exsertion, dimorphic upper pitchers, and unidirectionally upturned female flowers. It is assessed as Critically Endangered under the IUCN Red List criteria, based on its restriction to three subpopulations comprising few total individuals. Pitcher morphology …

Indian River Lagoon Shorelines
The spatial dataset: UCF_seagrasspersistence_IRL_LWL.shp was created with support from the Indian River Lagoon National Estuaries Program and Florida Sea Grant. These projects cumulatively led to creation of a living shoreline restoration prioritization model and hydrodynamic habitat suitability models for 1,550 km (963 miles) of estuarine shorelines in Indian River Lagoon (IRL) and Lake Worth Lagoon (LWL). The dataset presented herein represents persistence of seagrass throughout waters of the IRL and LWL.

New Butterfly Taxa And Findings From Genomic Analyses, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin
The Taxonomic Report of the International Lepidoptera Survey
Continuing our genomics-driven exploration of butterfly taxonomy, we integrate phylogenetic trees from all protein-coding genes with existing taxonomic and phenotypic knowledge and uncover further insights into butterfly systematics. As a result, one subgenus, 44 species, and 11 subspecies are proposed as new (type species in original combinations or type localities are listed in parentheses): Porphaurea Grishin, subgen. n. (Phoenicops porphyropis Meyrick & Lower, 1902) of Chaetocneme C. Felder, 1860 in Hesperiidae Latreille, 1809; Dione (Agraulis) lamasi Grishin, sp. n. (Peru: Cuzco) in Nymphalidae Rafinesque, 1815; Lasaia (Lasaia) chiapis Grishin, sp. n. (Mexico: Chiapas), Lasaia …
Improving Coral Restoration Outcomes Through Novel Molecular Applications, Matthew H. Gamache
Improving Coral Restoration Outcomes Through Novel Molecular Applications, Matthew H. Gamache
USF Tampa Graduate Theses and Dissertations
Coral reef ecosystems are declining globally from numerous stressors, including localized pollution, disease, and marine heatwaves induced by climate change. To preserve these ecosystems, it is critical to identify corals that can withstand stressors—primarily future marine heatwaves—and prioritize them for coral restoration efforts until these stressors are mitigated. Coral responses to thermal stress can be influenced by several partners, including mutualistic microalgae and a vast prokaryotic community. Here, I use advanced molecular techniques to examine which partners (coral host, algal symbiont, and microbial communities) are associated with coral health, how they contribute to holobiont physiology, and their potential to increase …
Examining Private Landowner And Stakeholder Attitudes, Perceptions, And Knowledge Of Prescribed Fire In Louisiana, Chloe E. Crawford
Examining Private Landowner And Stakeholder Attitudes, Perceptions, And Knowledge Of Prescribed Fire In Louisiana, Chloe E. Crawford
LSU Master's Theses
Periodic fire was a primary driver of ecosystems across the Southeastern United States for millennia; however, fire suppression policies have become pervasive in the United States and led to increased fuel loads in forests as well as reduced biodiversity and reduced disease resilience. Prescribed fire presents a risk mitigation strategy and land management tool whereby practitioners can apply fire to the landscape in a controlled manner, thus reaping the benefits of fire while minimizing the risks associated with fire. Land in Louisiana is primarily privately managed and owned, so state-level conservation goals cannot be met without private landowner participation. As …
