Conservation Status of the Longhead Darter, Percina macrocephala, in Kinnicock Creek, Kentucky

Percina macrocephala, the Longhead Darter, is rare throughout its range and endangered in Kentucky. One population in Kentucky occurs in Kinniconick Creek, Lewis County, and prior to this study was known from only a few specimens, mostly collected in 1981. In summer and early fall of 2007 and 2008, 55 reaches, spanning 54 stream km of Kinniconick Creek, were surveyed by snorkeling, electrofishing, or seining for P. macrocephala. We encountered 104 individuals of P. macrocephala in a 50 stream km segment from just below the town of Kinniconick to the town of Garrison. Fifteen of the 55 sampled reaches contained P. macrocephala. Most individuals were encountered in a middle section between the confluences of Laurel Fork and Town Branch; this area also contained many young-of-the-year, indicating successful reproduction and recruitment. Although we judge this species to be rare to uncommon in most of Kinniconick Creek, it is locally common in the middle section, and the population seems to be stable and perhaps the most robust in the state. We conservatively estimate a total population of 2000-5000 in the stream. Because this population appears to be migratory, and exhibits source-sink dynamics, it is susceptible to anthropogenic barriers (e.g., culvert crossings) that prevent movements

Reproductive Biology of the Frecklebelly Darter, Percina stictogaster (Teleostei: Percidae)

The reproductive biology of the Frecklebelly Darter, Percina stictogaster, was studied in the Red River, Menifee-Powell counties, Kentucky, from 2009-2012. Males and females mature at Age II. Spawning occurs from late February to early April in water temperatures of 7-16° C in areas with strong current (0.16-0.88 m/sec) and fine gravel substrates. A 52 mm SL female collected in early March had 100 mature ova. Aquarium observations confirm this species buries its eggs in a manner similar to other Percina darters. Fertilized eggs were about 2.5 mm in diameter, clear, demersal, and slightly adhesive. At 10° C eggs hatched in 18-25 days (100% survival) into larvae 7-8 mm TL. Larvae were initially benthic, but became pelagic 2- 3 days later. By about 11 mm TL, the yolk sac was absorbed, and the young returned to the bottom. In early June, young (about 2 months old) were 16-25 mm SL and had acquired diagnostic pigmentation. They occupied areas with Justicia sp. or coarse woody debris in low-velocity habitats, adjacent to riffles

Smoking intensity before and after introduction of the public place smoking ban in Scotland

AbstractA study was performed to determine whether cigarettes were smoked more intensely outside of public venues in Scotland, compared to indoors, after introduction of the public place smoking (PPS) ban. It was conducted in three waves: before the ban, immediately after and 6months after introduction. The study included 322 regular smokers of four cigarette brand variants. Filter analysis measurements were used to estimate the human-smoked yields of tar and nicotine from cigarettes smoked predominantly inside (before the ban) or outside (after the ban) public venues. Self-reported cigarette consumption data were also collected. Numbers of cigarettes smoked indoors in public places fell dramatically after the ban. There was a corresponding rise in smoking incidence in outdoor public locations. The ban did not significantly affect the total number of cigarettes smoked by the subjects over the weekends investigated. Human-smoked yields of tar and nicotine decreased slightly after the introduction of the ban and some reductions were significant. Therefore, smoking outdoors at public venues, following the PPS ban, did not increase smoking intensity. Any changes in smoking behaviour that may have occurred had little effect on mainstream smoke exposure or cigarette consumption for those that continued to smoke

HIV Risk Behaviors in Sub-Saharan Africa and Northern Thailand: Baseline Behavioral Data From Project Accept

Of 2.5 million new HIV infections worldwide in 2007, most occurred in Sub-Saharan Africa and Southeast Asia. We present the baseline data on HIV risk behaviors and HIV testing in Sub-Saharan Africa and northern Thailand from Project Accept, a community-randomized controlled trial of community mobilization, mobile voluntary counseling and testing (VCT), and post-test support services

Strategies for combating antibiotic resistance in bacterial biofilms

Biofilms, which are complexes of microorganisms that adhere to surfaces and secrete protective extracellular matrices, wield substantial influence across diverse domains such as medicine, industry, and environmental science. Despite ongoing challenges posed by biofilms in clinical medicine, research in this field remains dynamic and indeterminate. This article provides a contemporary assessment of biofilms and their treatment, with a focus on recent advances, to chronicle the evolving landscape of biofilm research
