Selectivity in fossil preservation as shown by a comparison of fossil and modern barnacle populations
Springer Science and Business Media LLC - Tập 9 - Trang 61-62 - 1968
Volume distribution curves were used to compare a modern (Balanus eburneus) and a fossil (Balanus concavus) barnacle population. The curve for the fossil population shows the selectivity of fossil processes, evidenced by a deficiency of smaller (young) membergs.
Condition of the quahog,Mercenaria mercenaria, from polluted and unpolluted waters
Springer Science and Business Media LLC - Tập 5 - Trang 155-160 - 1964
The meat volume-shell length regressions and the relationship of the meat volume to shell length in the formula, K=meat volume/shell lengthn, were used to compare the condition of quahogs,Mercenaria mercenaria, from polluted and unpolluted waters in Point Judith Pond, Rhode Island. Quahogs were collected in November, 1961 from adjacent waters on each side of the pollution line set by the state and......
A new elevation record for the New England cottontail (Sylvilagus transitionalis) in Virginia
Springer Science and Business Media LLC - Tập 17 - Trang 220-221 - 1976
During the period December 17, 1974 through February 23, 1975 the author captured 27 cottontails (Sylvilagus spp.) a total of 110 times at elevations between 1800–2140 ft. The majority of these captures took place in a 6- to 7-year-old clearcut between 1880 and 1980 ft. elevation. Of the 22 cottontails captured at this location, 20 (91 percent) were identified asSylvilagus transitionalis (New Engl......

A computerized system for the organized retrieval of life history information
Springer Science and Business Media LLC - Tập 15 - Trang 250-254 - 1974
This paper describes a computerized system for storage and retrieval of information on life history and environmental limits of organisms, which we have applied to the estuarine and nearshore organisms of the Texas coast. The system uses standard biological nomenclature instead of codes, and provides great flexibility both in search criteria and output format. Each entry for an organism is derived......

Springer Science and Business Media LLC - Tập 3 - Trang 130-135 - 1962
Three king mackerel each weighing about 27 pounds and about 44 inches fork length were taken in pound nets during October, 1961 off Swan Point, Kent County. These were part of a school that apparently invaded the upper Bay during late summer and fall. Meristic and morphometric data from them were compared with specimens from other points along the range of the species; the differences between them......
Eggs, larvae, and young of the white perch,Roccus americanus, with comments on its ecology in the estuary
Springer Science and Business Media LLC - - 1964
Eggs and larvae were reared in fresh water after stripping and fertilizing ripe ova from known brood fish found spawning in April and May in tidal fresh water. The early developmental stages and transforming postlarvae and very young fish were also identified in ichthyoplankton taken in tidal fresh and slightly brackish water up to 8%. salinity. The eggs are spherical (except for those with an att......
