NHEP Support for DES Shellfish Program 2005

For the past three years, Great Bay Coast Watch (GBCW) volunteers have provided the New Hampshire Department of Environmental Services (NHDES) Shellfish Program with significant assistance in performing tasks necessary in managing shellfish resources for human safety. This report describes a continuation of this mutually beneficial partnership

Experiences in Northern Bobwhite Propagation and Translocation in Ohio, 1978-2012

Ohio once boasted a population of 7 million northern bobwhites (Colinus virginianus). Catastrophic blizzards during 1976–1977 and 1977–1978 brought winter quail mortalities of 85% and 80%, respectively. Ohio’s bobwhite population was 430,000 in 1978, a 90% reduction from 1976. Remnant quail populations were small, isolated, and incapable of rapid recovery. The Ohio Department of Natural Resources (ODNR) initiated a statewide stocking effort to expedite population growth. The ODNR chose to propagate wild quail in captivity and release first-generation progeny (F1). Throughout 1980–1986, the ODNR released 65,000 F1 quail statewide. The ODNR monitored population response with North American Breeding Bird Survey, mail carriers, and roadside whistle-counts, but found little evidence of success. The ODNR evaluated postrelease survival and productivity of F1 hens (n = 100) and wild hens (n = 40) during 1984–1986 and deemed F1 hens inferior to wild hens. In 1993, the ODNR produced population models to develop minimum stocking rates for wild quail translocation, but insufficient numbers were captured. From 1998 to 2000 and 2005 to 2009, the ODNR translocated wild quail from Kansas to 5 Ohio sites with suitable, unoccupied habitat. Concurrently the ODNR translocated wild quail within Ohio. The ODNR conducted annual spring whistle-counts on all release sites during 1998–2012. Little or no evidence of sustained populations existed on sites after 7 years. Bobwhite translocation may yet show promise for population restoration, but evaluation should include 7–10 years of monitoring at a minimum

The Military Divorce: An Overview

Your Court Review Editors asked Mark Sullivan, nationally known expert on the military divorce, to contribute an article to this journal. Mark recruited colleagues Joe DeWoskin of Kansas City, KS, a retired Army officer, and Kansas District Court Judge Dan Wiley, who presides over domestic relations cases, to assist him. What follows is their round table discussion of the key issues in a military divorce

Efficacy of Targeted Mist-Netting to Capture Northern Bobwhites During the Non-Breeding Season in Ohio

Baited funnel traps and nightlighting are well established northern bobwhite (Colinus virginianus) capture techniques, but their use is not always appropriate, particularly on private land where cooperating landowners may place constraints on research activities. Alternative capture techniques may be more effective under conditions considered to be unfavorable for established techniques (e.g., periods with abundant natural food). Targeted mist-netting, where mist nets are erected near the known location of specific individuals, has been used to capture gallinaceous species and may be an effective alternative to established bobwhite capture techniques. We evaluated the effectiveness of using targeted mist-netting to capture bobwhites during the non-breeding season in Ohio. We tested for differences in survival and age and sex ratios of individuals captured with targeted netting and baited funnel traps. We captured 257 individuals with targeted netting during 1 October-28 February 2009–2011 and concurrently captured 253 individuals with baited funnel traps. There was a short-term influence of capture and handling, but there was no significant difference in post-capture survival of bobwhites captured with targeted netting or trapping. Capture rates of age and sex classes were similar (P 1⁄4 0.488 and P 1⁄4 0.973, respectively) between targeted netting and trapping. Body mass of bobwhites captured by targeted netting was less than that of bobwhites captured by trapping (P 1⁄4 0.009) suggesting that netting may provide more accurate estimates of body mass. We used targeted netting to capture bobwhites in a variety of situations where use of funnel traps was ineffective or problematic. Targeted netting was effective and often more compatible with constraints of working on private land than established capture techniques

Transcytosis and brain uptake of transferrin-containing nanoparticles by tuning avidity to transferrin receptor

Receptor-mediated transcytosis across the blood–brain barrier (BBB) may be a useful way to transport therapeutics into the brain. Here we report that transferrin (Tf)-containing gold nanoparticles can reach the brain parenchyma from systemic administration in mice through a receptor-mediated transcytosis pathway. This transport is aided by tuning the nanoparticle avidity to Tf receptor (TfR), which is correlated with nanoparticle size and total amount of Tf decorating the nanoparticle surface. Nanoparticles of both 45 nm and 80 nm diameter reach the brain parenchyma, and their accumulation there (visualized by silver enhancement light microscopy in combination with transmission electron microscopy imaging) is observed to be dependent on Tf content (avidity); nanoparticles with large amounts of Tf remain strongly attached to brain endothelial cells, whereas those with less Tf are capable of both interacting with TfR on the luminal side of the BBB and detaching from TfR on the brain side of the BBB. The requirement of proper avidity for nanoparticles to reach the brain parenchyma is consistent with recent behavior observed with transcytosing antibodies that bind to TfR
