“…A covariation was thus expected between phytoplankton productivity and the external material (e.g., nutrients associated with, terrestrial OM) inputs. For example, the removal of forest cover would result in increased delivery of dissolved P from the land to the lake, and then enhancing aquatic productivity (Bourbonniere and Meyers, 1996;Seki et al, 2004;Lammers et al, 2013). Indeed, the increases of phytoplankton abundance in Lake Fuxian generally follow the enrichment of TP in the sediment core (Fig.…”

“…6b). Phytol is derived from the side chain of different types of chlorophyll (e.g., phytoplankton and terrestrial plants), which tends to be ascribed to phytoplankton source in FX-1 core samples because such compound is labile and degrades fast in the terrestrial OM pool (Smittenberg et al, 2004;Lammers et al, 2013). 24-Ethylcholesta-5,22-dien-3β-ol (stigmasterol), 24-methylcholest-5-en-3β-ol (campesterol) and 24-ethylcholest-5-en-3β-ol (sitosterol) were found not only in land plants, but also in phytoplankton, including green algae, diatom and haptophytes (Volkman, 1986;Killops and Killops, 2005;Pearson et al, 2007;Volkman et al, 2008).…”

The resuspension and transportation of sediments affect the nutrient or contaminants cycles in water column. Therefore,hurricane-induced sedimentresuspension in coastal watersmay cause environment impacts on coastal ecosystems. In this study, field observed data during a hurricane event from the Rookery Bay National Estuarine Research Reserve (Rookery Bay NERR), Florida, were studied. Based on the relationship between sediment and turbidity, variations of turbidityin the Rookery Bay NERRwere discussed in this paper under the impact of the Hurricane Isaac in 2012. Time series analysis indicates thatHurricane Isaac causesthe substantialincrease of turbidity. Traditional direct regression analysis with raw data wasfound to result in poor correlation (R 2 <0.41) between wind speed and turbiditydue to the impacts of multi-factors in coastal waters of study region duringhurricane. Then Hanning Filterwas used to remove tidal effect, which shows some improvement of correlations (R 2 >0.6) between wind speed and turbidity. Further improvement was made by introducing a phase factor to account for the © 2016. This manuscript version is made available under the Elsevier user license http://www.elsevier.com/open-access/userlicense/1.0/ 2 lag time between the peak turbidity and peak wind speed, which lead to further improvement of the regression equation between wind speed and turbidity.By using Hanning Filter and phase factor, the regression equation between turbidity and wind speed fits wellwith observations (R 2 >0.96).Different lag time between wind speed and turbidityat different locations illustrated that wind had different effects on turbidity due to the locations and water depth.Based on the approximate empirical relationship between turbidity and sediment concentration,a regression equation between wind speed and sedimentconcentration wasderived approximately. The equation could be applied to approximately estimate the sediment concentration using wind speed during hurricane, especially with the strong wind speed above 4m/s.It can be used to provide technical supports for sediment assessment and coastal zoneresearch under extreme clime in the study region.

What controls home range relocations by estuarine fishes downstream from watersheds with altered freshwater flow?

We tracked locations of three fish species in two bays with differing hydrology in SW Florida in 2018–2020 to test the hypotheses about fish residency, movements, and environmental variables. Due to extensive watershed modification, one bay receives less freshwater and the other receives more relative to natural conditions. Home range duration differed for gray snapper (54 ± 6 days), red drum (132 ± 39), and goliath grouper (226 ± 63). Distances between relocation movements were similar for gray snapper and red drum (~ 1.2 km), but farther for goliath grouper (2.3 ± 0.3 km). Relocations were primarily seaward for gray snapper (83%) but varied for the other species. Home range duration related to age for goliath grouper (< 100 days for 1–1.5-year-olds, 300–425 days for 4–4.5-year-olds). Generalized additive models marginally related probability of gray snapper relocating to salinity and temperature whereas relocations of the other species occurred during all environmental conditions. Movement simulations lacking environmental cues produced similar emigration patterns as observed in tagged fish. Overall, results suggest that movements here are not strongly linked to environmental conditions, will be resilient to watershed restoration that should moderate salinity, and have implications for understanding the impacts of localized depletion due to recreational fishing.
