17 years later: Changes in Vegetation Structure, Burrow Dispersion and Size-class Distribution at a Gopher Tortoise (Gopherus polyphemus) Site in Alabama
(2017-05-15)
There are few studies that reevaluate vegetation structure at a gopher tortoise (Gopherus polyphemus) site after a long period of time in the southern Alabama or Florida panhandle portion of their range. The current study ...
Activity of Bats (Mammalia: Chiroptera) in Coastal South Carolina: an Acoustic Study
(2015-12-10)
Coastal South Carolina has not been the focus of previous studies on distribution of bats, but the proposal of an offshore wind farm has stimulated interest in how bats use coastal areas. Anabat acoustic detectors were ...
Adaptive developmental plasticity and hormetic effects in the zebra finch (Taeniopygia castanotis)
(2024-05-01)
Stressors experienced during development can have persisting detrimental effects on an individual’s phenotype, as well as indirect effects on the phenotype of offspring. However, developmental stressors can also be beneficial ...
Allosteric modulation of human melanocortin-4 receptor (MC4R) by zinc and copper ions and characterization of spotted sea bass MC4R
(2020-07-20)
Since the metal ions have been shown to play an important role in regulating signal transduction of G protein-coupled receptors (GPCRs), we investigated whether the Zn2+ and Cu2+ regulate the pharmacology of human ...
Analysis of p62-UBA interacting proteins
(2006-05-15)
Sequestosome 1/p62 interacts with and traffics K63-polyubiquitinated proteins through its ubiquitin associating domain (UBA). Herein we demonstrate that the hyperaccumulation of K63-polyubiquitinated proteins occurs in the ...
Analysis of Stable Isotopes of Hydrogen to Determine Migrational Source of Silver-Haired Bats (Lasionycteris noctivagans) in Alabama
(2008-08-15)
Signatures of deuterium obtained from claws of 21 silver-haired bats (Lasionycteris noctivagans) were used to estimate the nearest probable pre-migratory location of these bats. For 5 consecutive weekends beginning 28 ...
Applicability of Mitochondrial Genome Data to Annelid Phylogeny and the Evolution of Group II Introns
(2009-07-02)
Annelida is a very diverse group of segmented worms with over 16,500 described
species. They play an important role in both terrestrial and aquatic environments. Despite
this, their phylogenetic and evolutionary relationships ...
Application of High-Throughput Sequencing Methods to Spider Phylogenomics and Speciation with a Focus on the Mygalomorph Genus Aptostichus
(2018-04-24)
Spiders are massively abundant generalist arthropod predators that are found in nearly every ecosystem on the planet and have persisted for over 380 million years. Spiders have long served as evolutionary models for studying ...
Application of Metagenomics for Discovery of Natural Products and Virophages
(2016-05-24)
Metagenomics provided a powerful insight into an as-yet-uncultured bacterial community in different environments through construction of clone libraries and shotgun sequencing, therefore presenting potential in drug and ...
Assessing Some Key Approaches Used to Monitor and Study Populations of Birds
(2012-01-10)
Efforts to monitor birds and determine their distributions often make assumptions that allow for inference into parameters of interest but necessitate that potentially confounding factors be ignored. In any scientific ...
Assessing stress physiology of cane toads in Florida: tradeoffs with dispersal
(2021-04-08)
Physiological tradeoffs occur in organisms coping with their environments, which are likely to increase as populations reach peripheries of established ranges, potentially due to stress. Invasive species offer opportunities ...
THE BEHAVIORAL ECOLOGY AND CHEMICAL ANALYSIS OF MENTAL GLAND SECRETIONS OF BOTH SEXES OF GOPHER TORTOISES (GOPHERUS POLYPHEMUS)
(2021-07-19)
All living chelonian species (e.g., turtles and tortoises) are experiencing population declines, causing a new imperative to maintain the longevity of adults and to facilitate reproduction. One strategy in facilitating ...
Biogeographical and Genomic Analysis of Eleusine Species
(2021-12-06)
Abstract
Eleusine Gaertn. (Poaceae, subfamily Chloridoideae), is a small taxon of closely related and distinct diploids and tetraploids endemic to Africa that have been scrutinized from vegetative, floral, cytological, ...
Body shape evolution of African/Asian minnows of the genus Labeo Cuvier 1817 (Cyprinidae, Labeonini) and variations in Labeo parvus
(2018-07-30)
Morphological variation or similarities among organisms are not only a result of common evolutionary history but can also emerge because of convergent adaptations to similar habitats. Therefore, an organism’s morphology ...
Branched Amphiphilic Peptide Capsules (BAPCs): A promising platform for mRNA therapeutics delivery.
(2023-12-11)
mRNA therapeutics represent an emerging and powerful strategy for the treatment and
prevention of infectious and genetic diseases. However, mRNA molecules are large anionic
polymer that necessitate a delivery vector to ...
Broad characterization of structural variation and genetic differentiation in two hybridizing macaque species
(2018-07-25)
Speciation and hybridization drive all of the biodiversity seen on the plant. Understanding underlying mechanisms of these cornerstones of evolutionary genetics if of vital importance. Here we seek to apply a combination ...
Carotenoid-Based Dewlap Color as a Visual Signal in Social Communication of Brown Anoles (Norops sagrei)
(2007-12-15)
Carotenoids have been shown to be important integumentary coloring agents in many birds and fishes. The role of carotenoids as a prominent integumentary coloring agent of the dewlap has been noted in many Anoline lizards, ...
