Wavelet Analysis of Trends in Summer Flounder YOY and Spawner-Recruit Relationships

چکیده

Two climatic signals are most significant in affecting oceanographic and estuarine processes in the Mid-Atlantic Bight, the North Atlantic Oscillation (NAO) and the Pacific North American (PNA). The NAO is closely related to the Arctic Oscillation (AO) and primarily affects temperature. The PNA has a well-described teleconnection with the El Niño-Southern Oscillation (ENSO) and is dominantly an effector of precipitation and, thus, freshwater inflow, in the northeast region. The NAO has a well-described 8-year cycle and indications of a 4-yr periodicity that are superimposed on longer-term trends. These periodicities are known to profoundly effect estuarine oyster populations, including recruitment and mortality.

Behavioral ecology of young-of-the-year kelp rockfish, Sebastes atrovirens Jordan and Gilbert (Pisces: Scorpaenidae).

Young-of-the-year (YOY) kelp rockfish, Sebastes atrovirens, recruit initially to the canopy of the giant kelp, Macrocystis pyrifera (L.), along the coast of central California. During the summer of 1991, I observed major fluctuations in YOY kelp rockfish abundance in the canopy before the onset of a vertical migration downward to the Macrocystis holdfasts. Within the Macrocystis canopy, YOY kel...

Analysis of Trends in Sex Ratio, Implications for Natural Mortality, and Variation in Age-Length Keys in Summer Flounder

The analyses described herein use the biological database for summer flounder. The goals of these analyses are to answer the following questions to the extent permitted by this database. 1. Does information exist in the sex-ratio data that would support the need to construct a sex-explicit model for summer flounder? 2. Does information exist in the sex-ratio data that would support the need to ...

Trophic Ecology of Summer Flounder in Lower Chesapeake Bay Inferred from Stomach Content and Stable Isotope Analyses

Trophic studies of summer flounder Paralichthys dentatus have relied on traditional stomach content analyses to infer contributions of prey to species productivity. We applied both stable isotope and stomach content analyses to identify prey groups that are responsible for summer flounder productivity in lower Chesapeake Bay and to explore ontogenetic patterns in prey utilization. Summer flound...

The impact of young-of-the-year (YOY) fish predation on zooplankton dynamics and cascading effects down to phytoplankton were studied in lake enclosures using different densities of larval and juvenile European perch (Perca fluviatilis). Two experiments, one in June and one in August, were performed in Lake Dagstorpssjön, a slightly eutrophic lake in Scania, southern Sweden. In our experiments,...

A Meta-Analysis of the Habitat Carrying Capacity and Maximum Reproductive Rate of Anadromous Alewife in Eastern North America

—We analyzed the dynamics of eight populations of anadromous alewife Alosa pseudoharengus to determine their habitat carrying capacity, their maximum reproductive rate, and whether depensation occurs at low abundances. When spawner–recruit models are fit to data sets for individual alewife populations, the resulting parameter estimates are often poorly determined, biologically unrealistic, and ...
