Brief Note: Cactus Growth Changes as an Effect of Wind in Baja California Sur, México
(1995-12) Ortega-Rubio, Alfredo; Romero-Schmidt, Heidi; Vega-Villasante, Fernando
At Natividad Island, Baja California Sur, Mexico, we sampled a Ferocactus fordii var. grandiflorus population. All 50 individuals recorded in the northeast part of the island exhibited different degrees of prostration, directly related to their size and the direction of prevailing winds. Prostration was always oriented away from the direction of the dominant winds blowing over the island. There are essentially no previous publications of the effects of wind on the cactus growth form.
Brief Note: Smooth-billed Ani (Crotophaga ani L.), a New Species of Bird for Ohio
(1995-12) McLean, E. Bruce; White, Andrew M.; Matson, Timothy O.
A smooth-billed ani (Crotophaga ani L.) is reported from Ohio for the first time. The specimen (CMNH 68471) also represents the first inland state record for the United States. Confirmation of specific identity was obtained because of the significance of the record and some equivocal characteristics of the specimen. Care in field identification of extralimital anis is suggested.
Effect of Sustained Hand Grip Isometric Exercise on the Response of Erythrocyte 2,3-diphosphoglycerate in Untrained Men
(1995-12) Odje, Omokere E.; Ramsey, James M.
Experiments were designed to examine the role of erythrocyte 2,3-diphosphoglycerate (2,3-DPG) in a purely isometric exercise (hand-grip dynamometer) using the human arm as an in vivo model, since the literature contains very little information concerning the contribution of this phosphate in such exercise. 2,3-DPG provides a compensatory adjustment to facilitate oxygen delivery during hypoxic conditions. Its breakdown occurs under acidosis. Twelve untrained males, age ranging from 19 to 22 years, exercised using a hand-grip dynamometer at a sustained contraction of load greater than 50% of their individual maximal voluntary contractions (MVC) until exhaustion occurred between 1.8-3.2 min. There were no significant post-exercise changes in the mean levels of 2,3-DPG when measured as either |imolml * red blood cell (RBC) or mol-mol1 hemoglobin (Hb) immediately after exercise and 50 min after exercise even though immediate post-exercise increase in mean lactate levels and decrease in mean pH levels were significant (P <0.001). It is concluded that the duration of exercise in the present study was too brief for acidosis to affect 2,3-DPG metabolism.
Factors Controlling the Formation of Fossiliferous Beds in the Devonian Columbus Limestone at Marblehead Quarry, Marblehead, Ohio
(1995-12) Williams, Jack W.
This study uses taphonomic, sedimentologic, and stratigraphic evidence from fossiliferous beds in Marblehead Quarry to review two hypotheses: 1) that the fossiliferous beds at Marblehead Quarry represent a series of in situ paleocommunities, and 2) whether fossiliferous concentrations in carbonate environments are primarily caused by periods of low net sedimentation. The fossiliferous beds of Marblehead were relatively coarse grained, had a sharp basal contact, and contained fossil assemblages distinct from those within the fossil-poor intervals. Bed 1 was an amalgamation of three fining-upward sequences and contained relatively poorly-preserved fossils, while Beds 2-4 were thin, laterally persistent, and had well-preserved fossil assemblages. Bed 1 is interpreted as containing autochthonous assemblages during a period of increased current energy, but Beds 2-4 are interpreted as tempestites (i.e., rapidly deposited during storm events), and contain allochthonous fossil assemblages. Therefore, hypothesis 1 was partially disproved: Bed 1 and the fossil-poor intervals may represent in situ paleocommunities, but Beds 2-4 do not. Furthermore, Beds 2-4 provide an example of fossil concentrations that formed during periods of high net sedimentation, and do not fit the net sedimentation model of hypothesis 2. Nevertheless, sedimentation rate, whether high or low, appears to be the primary factor controlling the formation of fossil concentrations in the Columbus Limestone.
The Effect of Seasonal Change on the Group Size, Group Composition, and Activity Budget of White-Tailed Deer, Odocoileus virginianus
(1995-12) Sorensen, Vanessa A.; Taylor, Douglas H.
A free-ranging population of white-tailed deer (Odocoileus virginianus) located at the Miami University Ecology Research Center near Oxford, OH, was examined from October 1993 to February 1994 to determine seasonal changes in group size, group composition (number of males, females, and offspring), and behavior (feeding, locomotion, alert, and other behaviors). Observations took place at dusk in open pasture from a deer blind. Data were collected utilizing both scan samples and 60 second focal animal samples recorded on video. A significant increase in group size was found from fall to winter. No difference in group composition was found between seasons. Seasonal differences in behavior were found for all age/sex classes with an increase in feeding and a decrease in locomotion during the winter.
Limnological Characterization of the Tristate Oxbow Wetland (Ohio, Indiana)
(1995-12) Joo, Gea-Jae; Francko, David A.
We conducted a limnological study in bodies of water (Oxbow Lake, North Pond, Great Miami River, Ohio River) comprising the Tristate Oxbow Wetland region of southwestern Ohio and southeastern Indiana. This wetland, an extensive and important wildlife habitat located at the confluence of the Great Miami River and the Ohio River, is a region that has been and may in the future be impacted by industrial and commercial development. The present data suggest that Oxbow Lake and North Pond are strongly influenced by seasonal flooding patterns and resultant nutrient loading from the Great Miami River and the Ohio River. On the basis of physico-chemical and biological parameters, Oxbow Lake can be classified as a eutrophic to hypereutrophic system, while North Pond is mesotrophic to eutrophic.
Nest Site Characteristics of Great Blue Herons (Ardea herodias) in Northeast Ohio
(1995-12) Carlson, Becky A.
Seventeen Great Blue Heronries were surveyed in nine counties of northeast Ohio during the 1993 breeding season to determine nest site characteristics. Herons nested in 15 species of deciduous trees, selecting the taller trees at each site. Crown integrity was not a requisite for tree usage; repaired (reoccupied) nests and new colonies were established in dead trees as well as in healthy ones.
