Relative Strengths Of Competition For Space And Food In A Sessile Filter Feeder, David P. Lohse
Relative Strengths Of Competition For Space And Food In A Sessile Filter Feeder, David P. Lohse
VIMS Articles
Previous workers have demonstrated that sessile filter feeders compete for food and space, but little is known about the relative strengths of these two processes. To determine this, the density and position of barnacles (Balanus improvisus) in a unidirectional current were manipulated to alter the amount of competition for space and food, respectively. Results indicated that competition for space significantly reduced growth, and marginally reduced survivorship. Competition for food was also detected, but only among uncrowded individuals; thus, it appears to be the weaker of the two interactions. However, under crowded conditions, downstream individuals actually grew more than those upstream. …

This paper presents twenty-two species of nemerteans collected from various habitats in the York River, the Chesapeake Bay, and the Eastern Shore of Virginia during the summer of l962. For the presentation of supplementary descriptions, this number includes those already reported from the Chesapeake area (Ferguson and Jones, 1949) , besides seventeen species not previously reported from this region and two newly described species.

Monogenetic Trematodes Of Gulf Of Mexico Fishes. Part Xii. The Family Gastrocotylidae Price, 1943, William J. Hargis Jr.
VIMS Articles
This paper is the twelfth installment of the present series presenting the data concerning monogenetic trematodes collected during the years 1951-1954 at the Alligator Harbor Marine Laboratory of Florida State University. It comprises an emendation of the family Gastrocotylidae Price, 1943 and the subfamily Gastrocotylinae Sproston,1946 and descriptions and/or discussions of several species.
The new genera Scomberocotyle and Neothoracocotyle have been diagnosed with Scomberocotyle scomberomori (Koratha, 1955) n. comb. and Neothoracocotyle coryphenae (Yamaguti, 1938) n. comb., respectively as their type species. Emendations have been made in Gotocotyla Ishii, 1933, Thoracocotyle MacCallum, 1913, and Lithidocotyle Sproston, 1946. Pseudaxine mexicana Meserve, 1938, …
