Southern flounder Paralichthys lethostigma is a recreationally and commercially important species along the western Atlantic and northern Gulf of Mexico coasts that can exhibit complex early-life habitat-use patterns. Herein, we used an otolith microchemical approach to test the conventional wisdom that juvenile southern flounder spend most of their early life in low-salinity areas of estuaries, focusing on the largely unstudied population in the Mobile-Tensaw Delta, AL. Analysis of strontium… Expand
Comments on Lowe et al. “Otolith Microchemistry Reveals Substantial Use of Freshwater by Southern Flounder in the Northern Gulf of Mexico”
TLDR
It is suggested that the high levels of Sr/Ca ratios in the otoliths’ core of southern flounder does not reflect the saline conditions where larvae hatched, instead it reflects the location where the female progenitor hydrated the eggs. Expand
Response to “Comment on ‘Otolith Microchemistry Reveals Substantial Use of Freshwater by Southern Flounder in the Northern Gulf of Mexico’” by Pedro Morais
TLDR
While there is ample literature supporting the importance of maternal contributions to otolith microchemistry during vitellogenesis, it is contention that such contributions ultimately depend on the ecology and reproductive physiology of each species. Expand
Contingents of Southern Flounder from Subtropical Estuaries Revealed by Otolith Chemistry
TLDR
Examination of variation in migratory behavior and habitat use patterns in Southern Flounder Paralichthys lethostigma in the northwestern Gulf of Mexico finds that short postsettlement movements into low-salinity habitats, followed by estuarine and marine residency for the remainder of life are typical. Expand
Using Seasonal Variation in Otolith Microchemical Composition to Indicate Largemouth Bass and Southern Flounder Residency Patterns across an Estuarine Salinity Gradient
TLDR
It is determined that a definable relationship existed between salinity, water chemistry, and otolith Sr: Ca for both species and each fish was classified as either a freshwater resident, transient, or estuarine resident. Expand

The Gulf killifish, Fundulus grandis, is a vital component of saltmarsh ecosystems and an indicator species for environmental impacts, because of strong site fidelity. Also, their otoliths canExpand
Mercury Concentration in Two Estuarine Fish Populations across a Seasonal Salinity Gradient
TLDR
Mercury cycling in estuaries is complex, and little is known about the extent of Hg bioaccumulation in the ecologically diverse fishes that inhabit coastal areas, but both largemouth bass and southern flounder had negative relationships between individu... Expand
Spatial and Temporal Shifts in Estuarine Nursery Habitats Used by Juvenile Southern Flounder (Paralichthys lethostigma)
TLDR
Examining habitat use of young-of-year (YOY) southern flounder in the Galveston Bay complex using habitat distribution models and acoustic telemetry determined that habitat requirements for southernFlounder change with ontogeny and season. Expand
Occurrence of Juvenile Paralichthys lethostigma (Southern Flounder) in Tributaries of Chesapeake Bay
Abstract Paralichthys lethostigma (Southern Flounder) inhabits the continental shelf and estuarine waters of the Gulf of Mexico and the east coast of the North Atlantic, from peninsular Florida toExpand
Spatial and temporal shifts in suitable habitat of juvenile southern flounder (Paralichthys lethostigma)
TLDR
These models demonstrate the potential dynamics of suitable habitats for juvenile southern flounder and provide insight into ontogenetic shifts in habitat preference during the first year of life. Expand
Juvenile Winter Flounder (Pseudopleuronectes americanus) and Summer Flounder (Paralichthys dentatus) Utilization of Southern New England Nurseries: Comparisons Among Estuarine, Tidal River, and Coastal Lagoon Shallow-Water Habitats
TLDR
Examining WF and SF abundance and growth across each species’ broader geographic distribution revealed that southern New England habitats may constitute functionally significant nurseries, and indicated that juvenile SF have a geographic range extending further north than previously recognized.

Dynamics of white perch Morone americana population contingents in the Patuxent River estuary, Maryland, USA
TLDR
Both contingents appeared to have unique and complementary roles in the population dynamics of white perch, and evidence that the relative frequency of the brackish contingent has increased in year-classes with high juvenile recruitment suggested that freshwater habitats sustain a small but crucial reproductive segment of the population.

The influence of environmental factors on early life history patterns of flounders
TLDR
It is suggested that physical characteristics of the environment influence the early life history patterns of flounders by modifying behaviour of migrating larvae and distribution of larvae and juveniles suggests JapaneseFlounder spawn in close proximity to nursery grounds relative to flounder in Onslow Bay.

TLDR
Findings from the current study suggest density and condition of newly settled southern flounder vary at the bay scale, suggesting that parts of GBE do not function equally as nurseries. Expand

Incorporation of strontium into otoliths of an estuarine fish
TLDR
The experiments supported past applications of tracing estuarine and diadromous movements with otolith Sr/Ca chronologies, but emphasize the need to understand the underlying nature of Sr/ Ca gradients in estuaries, which may limit or confound reconstructions of estUarine habitat use. Expand
