Fish Assemblage Shift Following Abrupt Seagrass Loss in a Southwest Florida Tidal CreekNARA Subscribed
Phase shifts can occur in ecosystems because of external stressors. Such transitions from one state (e.g., clear water, seagrass) to another (e.g., phytoplankton blooms, bare substrate) continue to be documented worldwide. In estuaries, stressors related to urban and suburban development are often implicated in phase shifts, including altered hydrology and eutrophication. Tidal creeks may be especially prone to phase shifts as...
Spatial Mismatch Between Black Mangrove Avicennia germinans and Associated Herbivores Along the Range Edge EcotoneNARA Subscribed
Globally, many plant communities are reorganizing in response to climate change, often at different rates than associated fauna. Asynchrony in range expansion between plants and fauna could alter biotic constraints on plant populations. Tropical mangroves are limited by folivory, but little is known about the importance of herbivory on mangroves near distributional range limits in subtropical regions. We hypothesized that herb...
Isatin–pyridine oxime hybrids as potential reactivators of A-242-inhibited acetylcholinesteraseNARA Subscribed
Three new isatin–pyridine-2-oxime hybrids (AM01–03) were synthesized and experimentally evaluated as reactivators of acetylcholinesterase (AChE) inhibited by a surrogate of the nerve agent A-242, in comparison with their 4-oxime isomers previously reported by our research group. Furthermore, the interactions of these molecules within the AChE/A-242 complex were assessed through docking and molecular dynamics (MD) simulations....
Chytrids (phylum Chytridiomycota ) are zoosporic fungi that play key roles as parasites of aquatic microorganisms, yet they are understudied and genomic resources for algal-infecting chytrids remain scarce. Here, we present the first comparative genomic analysis of multiple isolates of a single chytrid species (order Rhizophydiales ) infecting the cyanobacterium Planktothrix agardhii . Isolates were collected from Sandusky Bay...
Climate Attribution in Fishery Stock Assessment: Case Studies From the Northeast U.S. Groundfish StocksNARA Subscribed
Climate change poses an unprecedented risk to fisheries ecosystems and economies globally. Ocean warming has led to observed geographic shifts and changes in the productivity of fish stocks. Due to the rapid pace of change in many of the world's oceans, there is a critical need to develop and apply scientific knowledge and tools that can help account for non‐stationarity and integrate climate and ecosystem drivers into fishery...
Muscle architectural and performance adaptations following an 8-week sprint-focused training interventionNARA Subscribed
Muscle fascicle length is a key determinant of sprint performance, with lengthening adaptations observed following eccentric strength training or combined sprint and resistance interventions. However, whether sprint-focused training can induce meaningful architectural adaptations, independent of concurrent sport-related training, remains unclear. Fourteen participants (10 female, 4 male; age 21.6 ± 3.3 years; body mass 68.0 ±...
