Estimated growth functions and size-age relationships of the hard clam, Mercenaria mercenaria, in the York River, Virginia

A study of the hard clam, Mercenaria mercenaria (Linnaeus, 1758) resources of Virginia is currently being conducted. One important aspect, their growth in this region, has been limited to the study of small juveniles (HAVEN & ANDREWS, 1957). Our objectives were to demonstrate that M. mercenaria growth functions could readily be derived and statistically contrasted, and, subsequently, the age-size relationship could be estimated

Hampton Roads tunnel corridor survey report for the Virginia Department of Highways

A survey of a proposed bridge tunnel corridor across Hampton Roads from Newport News to Portsmouth was undertaken by the Virginia ·Institute of .Marine Science at the request of the Virginia Department of Highways. The objective was the estimation of the densities of hard clams, oysters and bottom shell

Because of the volumes of data presented in the final report on An Investigation into Commercial Aspects of the Hard Clam Fishery and Development of Gear for the Harvest of Oysters , we are presenting here a brief summary of the results along with conclusions and recommendations

Writing a Research Paper From Beginning to End

Universities take pride in the research their school produces, as it demonstrates their dedication to advancing knowledge and pushing the boundaries of various fields, not just STEM. Research by definition is an inquiry using current sources to guide and establish new facts in any field of study. Undergraduate student research falls under this umbrella of advancement and is a critical component of the research culture at any institution. A research paper includes four important sections: the abstract, introduction, methods, and results section. Each section takes the audience through the steps implemented by the student to answer their research question and conclude with their findings. Upon completion of the research paper, students open themselves up to the opportunity of publishing their work in academic research journals. This article aims to address how to write a research paper that is suitable for publication

Can moral case deliberation in research groups help to navigate research integrity dilemmas? A pilot study

There is an increased focus on fostering integrity in research by through creating an open culture where research integrity dilemmas can be discussed. We describe a pilot intervention study that used Moral Case Deliberation (MCD), a method that originated in clinical ethics support, to discuss research integrity dilemmas with researchers. Our research question was: can moral case deliberation in research groups help to navigate research integrity dilemmas? We performed 10 MCDs with 19 researchers who worked in three different research groups from three different disciplinary fields at a university in the Netherlands. We analyzed the dilemmas and values discussed, sent out a survey questionnaire to assess self-perceived moral competencies, and conducted in-depth interviews. We found research integrity dilemmas pertained to authorship disputes, supervision of junior co-workers, and questionable handling of data. Participants perceived the majority of moral competencies to a higher degree during the MCD when compared to perceiving them in daily practice afterward. Interviewees told us that they felt most comfortable discussing dilemmas among peers with whom they were not closely affiliated. We conclude that MCD sessions could be relevant in navigating research integrity dilemmas, but that revisions to ensure commitment and safety are required.</p

The Effect of Tropical Storm Agnes on Oysters, Hard Clams, Soft Clams, and Oyster Drills in VIrginia

Tropical Storm Agnes had a major effect on the molluscan fisheries of Virginia. One effect was the direct mortality of oysters, Crassostrea virginiaa, in the upper parts of many estuaries. Typical losses on leased bottoms were: the James River, 10%; the York River, 2%; the Rappahannock River, 50%; and the Potomac River tributaries (Virginia) 70%. Economic loss was in excess of 7.9 million dollars. There was a nearly complete absence of oyster larvae attachment (setting) in 1972. Other effects of Agnes included a nearly complete loss of soft clams, Mya arenaria, in the Rappahannock River. Hard clams, Meraenaria meraenaria, were killed in the upper part of the York River. Oyster drills, Urosalpinx ainerea, were eliminated from the Rappahannock and reduced greatly in numbers in the York and James Rivers.https://scholarworks.wm.edu/vimsbooks/1074/thumbnail.jp
