We used short-term recoveries (n = 3587) of tagged red drum Sciaenops ocellatus to directly estimate age- and length-based selectivity patterns using generalized linear models. The most parsimonious models were selected using AIC, and standard deviations were estimated using simulations. Selectivity of red drum was dependent upon the regulation period in which the fish was caught, the gear used to catch the fish (i.e., hook-and-line, gill nets, pound nets), and the fate of the fish upon recovery (i.e., harvested or released); models including all first-order interactions between main effects outperformed models without interactions. Selectivity of harvested fish was generally dome-shaped and shifted toward larger, older fish in response to regulation changes. Selectivity of caught-and-released red drum was highest on the youngest and smallest fish in the early and middle regulation periods, but increased on larger, legal-sized fish in the late regulation period. These results suggest that catch-and-release mortality has consistently been high for small, young red drum, but has recently become more common in larger, older fish. This method of estimating selectivity from short-term tag recoveries is valuable because it is simpler than full tag-return models, and may be more robust because yearly fishing and natural mortality rates do not need to be modeled and estimated.}, number={3}, journal={FISHERIES RESEARCH}, author={Bacheler, Nathan M. and Hightower, Joseph E. and Burdick, Summer M. and Paramore, Lee M. and Buckel, Jeffrey A. and Pollock, Kenneth H.}, year={2010}, month={Mar}, pages={266–275} } @article{bacheler_paramore_burdick_buckel_hightower_2009, title={Variation in movement patterns of red drum (Sciaenops ocellatus) inferred from conventional tagging and ultrasonic telemetry}, volume={107}, number={4}, journal={Fishery Bulletin (Washington, D.C.)}, author={Bacheler, N.

However, the recent growth of concentrated animal feeding operations (CAFOs) presents a greater risk to water quality because of both the increased volume of waste and to contaminants that may be present (e.g., antibiotics and other veterinary drugs) that may have both environmental and public health importance. Based on available data, generally accepted livestock waste management practices do not adequately or effectively protect water resources from contamination with excessive nutrients, microbial pathogens, and pharmaceuticals present in the waste. Impacts on surface water sources and wildlife have been documented in many agricultural areas in the United States. Potential impacts on human and environmental health from long-term inadvertent exposure to water contaminated with pharmaceuticals and other compounds are a growing public concern. This work-group, which is part of the Conference on Environmental Health Impacts of Concentrated Animal Feeding Operations: Anticipating Hazards—Searching for Solutions, identified needs for rigorous ecosystem monitoring in the vicinity of CAFOs and for improved characterization of major toxicants affecting the environment and human health. Last, there is a need to promote and enforce best practices to minimize inputs of nutrients and toxicants from CAFOs into freshwater and marine ecosystems.}, number={2}, journal={ENVIRONMENTAL HEALTH PERSPECTIVES}, author={Burkholder, JoAnn and Libra, Bob and Weyer, Peter and Heathcote, Susan and Kolpin, Dana and Thorne, Peter S. and Wichman, Michael}, year={2007}, month={Feb}, pages={308–312} } @article{mccoy_davis_camper_khan_bharathi_2007, title={Influence of rhizome propagule size on yields and triterpene glycoside concentrations of black cohosh [Actaea racemosa L. syn Cimicifuga racemosa (L.)

Nuttal] is a native North American medicinal plant traditionally harvested for its rhizomes and roots. Black cohosh products were listed in the top 10 selling herbal supplements from 2002 to 2005. As a result of increasing commercial demand, there is a need to develop propagation protocols suitable for production purposes to replace current methods of harvesting from wild populations. The objectives of this study were to 1) determine optimal rhizome propagule division size for successful regeneration, 2) analyze triterpene glycoside concentrations, 3) quantify survival rates after 3 years of production, and 4) evaluate net yield results. Experimental sites included a shade cloth structure in an agricultural research field, a shaded forest interior, and a shaded, disturbed forest edge. Plant emergence, growth, and survival were assessed at each site over a 3-year period. Optimal rhizome division size for propagation was a 10 to 30-g section originating from terminal rhizome portions. Rhizome survival averaged 97% among all treatments tested by year 3 at three sites. No differences in mean triterpene glycoside concentrations were detected between rhizome size classes or sites tested. Mean cimiracemoside concentrations ranged from 0.80 to 1.39 mg·g–1 d/w tissue, deoxyactein 0.47 to 0.92 mg·g–1, and actein 10.41 to 13.69 mg·g–1. No differences in triterpene levels were detected between flowering and nonflowering plants, nor were yields reduced. Net yields from a shade cloth production site were 9 and 17 times higher than a disturbed forest edge and forest site respectively. Black cohosh is a strong candidate for commercial propagation under adequate site selection.}, number={1}, journal={HORTSCIENCE}, author={McCoy, Joe-Ann and Davis, Jeanine M. and Camper, N.

Recently, a peptide derived from the myristoylated alanine-rich C kinase substrate protein NH2-terminal sequence (MANS) was shown to inhibit methacholine (MCh)-induced mucin secretion from airway mucous cells by >90%. We studied the effect of intranasal pretreatment with this peptide on specific airway conductance (sGaw) during challenge with MCh in mice with allergen-induced mucous cell metaplasia. sGaw was noninvasively measured in spontaneously breathing restrained mice, using a double-chamber plethysmograph. Pretreatment with MANS peptide, but not a control peptide [random NH2-terminal sequence (RNS)], resulted in partial inhibition of the fall in sGaw induced by 60 mM MCh (mean ± SE; baseline 1.15 ± 0.06; MANS/MCh 0.82 ± 0.05; RNS/MCh 0.55 ± 0.05 cmH2O/s). The protective effect of MANS was also seen in mice challenged with allergen for 3 consecutive days to increase airway hyperresponsiveness, although the degree of protection was less (baseline 1.1 ± 0.08; MANS/MCh, 0.65 ± 0.06; RNS/MCh 0.47 ± 0.03 cmH2O/s). Because routine sGaw measurement in mice includes nasal airways, the effectiveness of MANS was also confirmed in mice breathing through their mouths after nasal occlusion (baseline 0.92 ± 0.05; MANS/MCh 0.83 ± 0.06; RNS/MCh 0.61 ± 0.03 cmH2O/s). In all instances, sGaw in the MANS-pretreated group was ∼35% higher than in RNS-treated controls, and mucous obstruction accounted for ∼50% of the MCh-induced fall in sGaw. In summary, mucin secretion has a significant role in airway obstruction in a mouse model of allergic asthma, and strategies to inhibit mucin secretion merit further investigation. }, number={1}, journal={JOURNAL OF APPLIED PHYSIOLOGY}, author={Agrawal, A. and Rengarajan, S. and Adler, K.

We reconstruct the phylogenetic relationships within Hippoboscoidea using maximum parsimony and Bayesian methods based on nucleotide sequences from fragments of four genes: nuclear 28S ribosomal DNA and the CPSase domain of CAD, and mitochondrial 16S rDNA and cytochrome oxidase I. We recover monophyly for most of the presently recognized groups within Hippoboscoidea including the superfamily as a whole, the Hippoboscidae, the Nycteribiidae, the bat flies, and the Pupipara (=Hippoboscidae+Nycteribiidae+Streblidae), as well as several subfamilies within the constituent families. Streblidae appear to be paraphyletic. Our phylogenetic hypothesis is well supported and decisive in that most competing topological hypotheses for the Hippoboscoidea require significantly longer trees. We confirm a single shift from a free-living fly to a blood-feeding ectoparasite of vertebrates and demonstrate that at least two host shifts from mammals to birds have occurred. Wings have been repeatedly lost, but never regained. The hippoboscoid ancestor also evolved adenotrophic viviparity and our cladogram is consistent with a gradual reduction in the motility of the deposited final instar larvae from active burrowing in the soil to true pupiparity where adult females glue the puparium within the confines of bat roosts.}, number={1}, journal={MOLECULAR PHYLOGENETICS AND EVOLUTION}, author={Petersen, Frederik Torp and Meier, Rudolf and Kutty, Suiatha Narayanan and Wiegmann, Brian M.}, year={2007}, month={Oct}, pages={111–122} } @article{burdick_hightower_2006, title={Distribution of spawning activity by anadromous fishes in an Atlantic slope drainage after removal of a low-head dam}, volume={135}, ISSN={["1548-8659"]}, DOI={10.1577/T05-190.1}, abstractNote={Abstract}, number={5}, journal={TRANSACTIONS OF THE AMERICAN FISHERIES SOCIETY}, author={Burdick, Summer M. and Hightower, Joseph E.}, year={2006}, month={Sep}, pages={1290–1300} }
