Seasonal Phytoplankton Assemblages Associated With The Chesapeake Bay Plume, Harold G. Marshall Jan 1991

Seasonal Phytoplankton Assemblages Associated With The Chesapeake Bay Plume, Harold G. Marshall

Biological Sciences Faculty Publications

Waters associated with the Chesapeake Bay plume were highly variable, unstable, and subject to the influence of flow patterns into and out of the Bay. Seasonal phytoplankton assemblages were identified for this region, with the phytoplankton development similar to the seasonal spring-fall growth maxima over the shelf, yet influenced by the multi-pulsed patterns often noted in the lower Bay. Major dominants included species common to both the shelf and lower Chesapeake Bay.

A Resource Inventory And Impact Analysis Of Great Bog And The Horse Point Delta/Esker System, Problems In Environmental Science Course (Biology 493), Colby College, Biologists Organized For Ecosystem Assessment, Colby College

Colby College Watershed Study: Other Area Studies

In May of 1990, Tilcon-Maine, Inc. submitted an application to mine gravel on the east side of Horse Point Road on Horse Point in the Town of Belgrade. The project site covers 46 acres and the proposed excavation covers 16 acres. An estimated 740,000 cubic yards of material will be removed over a period of six or seven years (Pfister, pers. comm.). According to Tilcon (Timson et al., 1990) the maximum depth of the pit will be 78 feet and the bottom of the pit will be a minimum of 6 feet above the water table. At the present time …

The Cladocera Of Lake West Okoboji, Iowa - Revisited, Kenneth L. Lang Jan 1990

The Cladocera Of Lake West Okoboji, Iowa - Revisited, Kenneth L. Lang

Journal of the Iowa Academy of Science: JIAS

Seven stations, established in 1968 to sample Cladocera, were sampled again, using the same methods, in 1988. Seven species, all of them in low abundance, are new records for Lake West Okoboji. In 1988, there was little difference 1) in the ranking of the stations relative to abundance of cladocerans, 2) the distribution and abundance of the species by habitat-type, 3) the seasonality of the predominant species in the specific habitats, 4) the temporal patterns of the number of species and total cladoceran abundance in the specific habitats, compared to 1968. On the average there were more species but lower …

Plant-Parasitic Nematodes In Iowa, Don C. Norton Jan 1989

Plant-Parasitic Nematodes In Iowa, Don C. Norton

Journal of the Iowa Academy of Science: JIAS

Ninety-nine species of plant-parasitic nematodes are recorded from Iowa. Twenty-seven are new state records. Most samples were collected from around maize or from prairies or woodlands. Similarity (Sorensen's index) of species was highest for the maize-prairie habitats (0.49), compared with maize-woodlands (0. 23), or prairie-woodland (0. 3 7) habitats. Nematode communities were most diverse in prairies with a Shannon-Weiner index (H') of 2.74, compared with 1.65 and 1.07 for woodlands and maize habitats, respectively. Evenness of species (J') was 0.41, 0.78, and 0.48 for maize, prairies, and woodlands, respectively.

Using Life History And Ecology As Tools To Manage A Threatened Salamander Species, Scott R. Mcwilliams, Marilyn D. Bachmann Jan 1988

Using Life History And Ecology As Tools To Manage A Threatened Salamander Species, Scott R. Mcwilliams, Marilyn D. Bachmann

Journal of the Iowa Academy of Science: JIAS

Selected aspects of the life history and ecology of the small-mouthed salamander (Ambystoma texanum Matthes) relevant to the management of this threatened species in Iowa are presented. The population studied utilizes flooded woodland habitat during courtship, breeding and egg laying, and during the entire larval period. Larval foraging strategies in this habitat included ontogenetic but no diel shifts in prey selection. Synchronous, nocturnal breeding migration allowed effective use of drift fences fur capture of adults used in captive breeding, courtship behavior studies, and the estimation of breeding population size. Large numbers of spennatophores, apparently indiscriminate mate choice, and the relatively …
