The Seasonal And Diel Use By Juvenile And Adult Finfishes Of A Mesohaline Intertidal Creek On The York River, Virginia (Menidia Menidia, Fundulus Heteroclitus, Leiostomas Xanthuras, Brevoortia Tyrannus, Anchoa Mitchilli), Robert W. Middleton
Dissertations, Theses, and Masters Projects
An intertidal creek off the York River, Va. was sampled for juvenile and adult fishes during the spring, summer, and fall of 1981. Over 21,500 individuals of 14 species were collected using a block net technique. Ninety-eight percent of the total number was derived from five species which were, in order of abundance; Brevoortia tyrannus, Fundulus heteroclitus, Anchoa mitchilli, Leiostomus xanthurus, and Menidia menidia. Diel variations in abundance were indicated for A. mitchilli and M. menidia juveniles which were mostly captured at night and for M. menidia adults, L. xanthurus juveniles, and F. heteroclitus of all ages which were typically …

The York River: A Brief Review Of Its Physical, Chemical And Biological Characteristics, Michael E. Bender
Reports
The purpose of this paper is to provide an overview of the physical, chemical and biological characteristics of the York River, Virginia. The river is formed by the confluence of the Mattaponi and Pamunkey rivers at West Point, Virginia. It is tidal over its entire length and flows to the western shore of Chesapeake Bay.
The Community Metabolism And Nutrient Dynamics Of A Shoal Sediment In A Temperate Estuary, With Emphasis On Temporal Scales Of Variability (Sediment/Water Exchange, Euphotic, Chloraphyll-A, Virginia), William M. Rizzo
Dissertations, Theses, and Masters Projects
The oxygen metabolism and exchange of nutrients between sediment and water were studied on a submerged sandy shoal in the York River, Virginia from March to December 1983. Particular emphasis was placed on the variability in metabolic estimates over different time scales. Variation in oxygen metabolism was examined over the photoperiod, between successive sampling days, between tidal condition (mid-day high vs. low tide), and among seasons. Morning NP was significantly greater than afternoon NP over the study. Mean hourly NP and R were significantly different between successive days in 4 of 6 tests, and 2 of 6 tests respectively. R …
