First record of piscivory in ghost pipefishes (Teleostei, Solenostomidae) revealed by micro‐computed tomographyNARA Subscribed
Ghost pipefishes (Solenostomidae) have been regarded as specialist crustacean feeders since the 1960s, an inference resting on two primary dietary accounts. We report the first documented evidence of piscivory in the family based on micro‐computed tomography (micro‐CT) examination of voucher specimens of Solenostomus snuffleupagus and S. cyanopterus . Two head‐first teleost prey, both identified as gobiids, were recovered from...
We have attempted to re-establish bay scallops to the Virginia, U.S.A. coastal bays and document the dynamics of the restoration effort. Bay scallops ( Argopecten irradians ) once flourished in the eelgrass ( Zostera marina ) of the Virginia coastal bays. Eelgrass wasting disease led to declines, and both eelgrass and scallops were completely lost after a 1933 hurricane. The Virginia Institute of Marine Science (VIMS) led a su...
Introduction Dexmedetomidine has been used to treat toxicologic conditions, but high-quality data on its use for this indication in the emergency department setting are lacking. We sought to characterize the use of dexmedetomidine in this context. Methods We conducted a dual-center retrospective cohort study of patients treated with dexmedetomidine in two academic emergency departments. We included patients who received dexmed...
Dryland ecosystems cover 41% of Earth's land surfaces, account for 44% of cultivated lands and 60% of food sources, and make large contributions to the global water and carbon cycles. However, these ecosystems are experiencing unprecedented extremes including heatwaves, floods, and droughts as well as hotter temperatures and often declining water resource availability. These ecosystems are some of the most challenging to monit...
Global patterns and regional insights into kelp forest protection, restoration, and stewardshipNARA Subscribed
Kelp forests are among the most extensive and productive coastal ecosystems, yet they remain underrepresented in global conservation policy despite widespread declines driven by interacting global- (i.e., ocean warming, marine heatwaves) to local-scale stressors. At the same time, kelp conservation and restoration efforts are expanding rapidly across regions, but measures of success and syntheses tend to primarily focus on eco...
Two new species of the eel genus Facciolella from Taiwan , northwestern Pacific Ocean ( Anguilliformes: Nettastomatidae )NARA Subscribed
Two new species of the duckbill eel genus Facciolella are described based on specimens collected off Taiwan, representing the first record of the genus in the western Pacific Ocean. Facciolella bicolor sp. nov ., based on three types, is most similar to F. smithi in having a bicoloured body and trunk, and can be distinguished by more preanal lateral‐line pores and preanal vertebrae and a combination of characters. Facciolella...
Macroalgal removal increases calcifier abundance and promotes coral settlement on inshore reefsNARA Subscribed
The indirect effects of macroalgal biomass on coral settlement remain poorly understood, particularly on degraded inshore reefs characterised by high algal cover. We investigated how macroalgal removal influences benthic community composition and subsequent coral settlement and persistence by deploying 240 terracotta settlement tiles across experimental plots at two inshore reefs (Yunbenun, Great Barrier Reef, Australia). On e...
