One of the world’s largest “blue carbon” ecosystems, Louisiana’s tidal wetlands on the US Gulf of Mexico coast, is rapidly being lost. Louisiana’s strong legal, regulatory, and monitoring framework, developed for one of the world’s largest tidal wetland systems, provides an opportunity for a programmatic approach to blue carbon accreditation to support restoration of these ecologically and economically important tidal wetlands. Louisiana’s coastal wetlands span ∼1.4 million ha and accumulate 5.5–7.3 Tg yr−1 of blue carbon (organic carbon), ∼6%–8% of tidal marsh blue carbon accumulation globally. Louisiana has a favorable governance framework to advance blue carbon accreditation, due to …

Habitat Use And Movements Of Parrotfishes In A Hawaiian Coral Reef Seascape, Senifa F. Annandale, Jason P. Turner, Daniel L. Lippi, Michael Dance, R. J.David Wells, Jay R. Rooker

Faculty Publications

Parrotfishes (family Scaridae) are important to coral reef ecosystems and highly prized by both commercial and recreational fishers in the Hawaiian Islands. Although parrotfishes are known to be strictly diurnal, our knowledge of their habitat use and movement patterns across daily timescales in tropical systems is still somewhat limited. Here, acoustic telemetry was used to determine parrotfish habitat use and movements within a coral reef seascape at Puakō, Hawai‘i. An array of acoustic receivers was deployed in a nearshore reef to track fine-scale movements of two common species: ember parrotfish (Scarus rubroviolaceus) and palenose parrotfish (Scarus psittacus). Transmitters were mounted …

Exploring The Metabolic And Mitogenic Potential Of A Hyper-Stable Variant Of Fgf1, Emma Starr, Oshadi Edirisinghe, Thallapuranam Krishnaswamy Suresh Kumar

Inquiry: The University of Arkansas Undergraduate Research Journal

Fibroblast growth factors (FGFs) are a family of 22 human cytokines involved in critical cellular processes, such as proliferation, differentiation, metabolism, angiogenesis, tumor metastasis, and wound healing. Among these, fibroblast growth factor 1 (FGF1) possesses a powerful mitogenic potential as it can nonspecifically bind to all four FGF receptors. However, the therapeutic applications of FGF1 are hindered by its inherent thermal and proteolytic instability, especially at physiological temperatures. This is believed to be attributed to the heparin-binding pocket at the C-terminus, which contains numerous positively charged residues that repel each other. To combat this instability, FGF1 binds to a negatively …
