Effect of Hydrologic Restoration on the Habitat of the Cape Sable Seaside Sparrow, 2008 – Final Report

This document summarizes the activities that were accomplished in 2008, the sixth year of the research project “Effect of hydrologic restoration on the habitat of the Cape Sable seaside sparrow”, a collaborative effort among the US Army Corps of Engineers, Everglades National Park, Florida International University, and the US Geological Survey (Florida Integrated Science Center). The major activities in 2008 included field work, data analysis, and presentations. Jay Sah presented the results of 6th year field work at the Cape Sable seaside sparrow (CSSS) Fire Meeting 2008, held on December 2-3 at the Krome Center, Homestead, Florida. In the same meeting, Mike Ross presented results from a related USFWS-funded project on encroachment pattern of woody plants in Cape Sable seaside sparrow habitat.

Cape Sable Seaside Sparrow Habitat – Vegetation Monitoring: FY 2009 - Final Report

This document summarizes the activities that were accomplished in FY 2009 on the research project “Cape Sable seaside sparrow habitat – Vegetation Monitoring”, a collaborative effort among the US Army Corps of Engineers, Florida International University, and the US Geological Survey. The major activities in 2009 included field work, data analysis and presentations. The results of 2009 field work were presented at the 4th International Congress of Fire Ecology and Management, Savannah, GA from November 30 to Dec 5, 2009 and at the Cape Sable seaside sparrow (CSSS) Fire Meeting, held at the Krome Center, Homestead, FL on December 8, 2009. Field sampling was conducted between March 23 and June 3, 2009, during which we resurveyed 234 sites: 191 Census sites, 3 sites on Transect B, 7 sites on Transect D, and 33 sites on Transect F. The number of sites sampled in 2009 was higher than in any previous year, primarily because a large number of sites burned in Mustang Corner fire and three other wild fires in 2008 were included in 2009 sampling. At all sites surveyed in 2009, we recorded structural and compositional vegetation parameters following the methods used in previous years (2003-2008) and tagged shrubs and trees (woody plants > 1 m) present in the 5 x 60 m plots. In addition, for the first time, we measured height of sawgrass (Cladium jamaicense) stubble in the compositional plots at the sites that were burned in 2008. Field data were entered by field crews, and were thoroughly checked by Jay Sah (Co-PI) to ensure that the data were complete, correct, and compliant with sampling methodologies. The data are stored under a project folder on a shared network drive maintained by the Southeast Environmental Research Center (SERC) at FIU. The shared network drive is backed up daily.

"Unruly women and semiotic spaces": Jay Verney's a mortality tale

Written at a time of significant changes for women and for women writers in Queensland, Australia, Jay Verney's A Mortality Tale (1994), privileges women's experiences of place and seeks to redeem the feminine from its entrapment in masculine stories/discourses of self and place. This chapter draws on Julia Kristeva's conceptualisation of the semiotic as a way of reading Verney's witty and reflective re-articulation of phallocentric orderings of spatiality and gender.

虾夷扇贝Patinopecten yessoensis (Jay)和仿刺参Apostichopus japonicus (Seienka)多倍体诱导研究

本文采用化学方法诱导了虾夷扇贝Patinopecten yessoensis (Jay)和仿刺参Apostichopus japonicus (Selenka)的多倍体。采用6－二甲基氨基嘌呤（6－dimethylaminopurine）抑制虾夷扇贝极体释放，研究了诱导三倍体的实验条件、技术工艺以及三倍体虾夷扇贝幼虫的生长和培育方法。结果表明，使用6－二甲基氨基嘌呤（6－DMAP）可诱导17.3%-100.0%的三倍体虾夷扇贝面盘幼虫。筛选并优化了生产中操作简便、高效、成活率高的诱导条件，并研究出在扇贝三倍体诱导中批量获得受精卵、处理及培育的技术工艺，对扇贝三倍体的规模化诱导及培育等生产性应用具有较高的参考价值。报道了采用细胞松弛素B（cytochalasin B）、秋水仙素（colchicine）、6－DMAP以及咖啡因（coffeine）等药物抑制虾夷扇贝第一极体（PB_1）释放、PB_1和第二极体（PB_2）释放以及抑制第一次卵裂等方法诱导四倍体的结果。结果表明，CB、6－DMAP和秋水仙素抑制扇贝第一次有丝分裂诱发四倍体的比例低于25%，而采用CB抑制PB_1可有效地诱导产生四倍体，从授精后42min提前到15-22min开始处理，抑制PB_1的放出有助于提高四倍体的比例，在12 ℃，处理开始和终上时间分别在授精后20－22min和60－62min时，面盘幼虫四倍体率最高，为56.5%。对CB处理抑制受精卵PB_1释放的处理组胚胎的染色体分离状况进行了观察研究。对照组受精卵具有19条四分体染色体，经过减数分裂I期（meiosis I）和减数分裂II期（meiosis II），放出PB_1和PB_2，受精卵的发育具有不同步性。处理组受精卵在第二次减数分裂中出现了“三级分离“、“联合二级分离“和“独立二级分离“等特殊的分离类型，初步分析了CB抑制第一极体放出的机理。对三倍体虾夷扇贝的繁殖潜力和卵子的大小进行了观察研究，三倍体扇贝具一定的繁殖能力，三倍体雌贝平均产卵3.26 * 10~6个，而相同壳长二倍体贝为1.45 * 10~7，三倍体产卵量仅为二倍体产卵量的22.5%。三倍体卵子产出后，形状不规则，卵子平均直径为87.25μm，比二倍体大11.7%，卵子体积比二倍体大39.4%。利用CB抑制第一极体释放诱导了虾夷扇贝的四倍体，诱导率为41.5%。首次报道了仿刺参Apostichopus japanicus (Selenka)多倍体诱导的结果。采用紫外线照射的海水成功地使海参分别单独产卵、排精，从而准确地控制了海参的人工授精后处理的时间。采用0.2、0.4mg/L CB 抑制受精卵第一极体释放以及10、20、30和40mg/L 的6－DMAP 分别抑制PB_1、PB_2放出的方法诱导了仿刺参的多倍体。研究了诱导的药物浓度、处理时间以及处理开始时间等，同时对幼体的成活率等进行了探讨。结果表明，2种药物均可诱导仿刺参产生三倍体和四倍体，从效果上看，采用CB抑制PB_1诱导，到达小耳幼体时，可产生9.7%-21.3%的四倍体。6－DMAP抑制PB_2放出诱导三倍体，三倍体诱导率介于7.5%-25.8%之间。

Divergent selection and realized heritability for growth in the Japanese scallop, Patinopecten yessoensis Jay

In order to improve the production and accurately estimate response to selection, divergent selection for growth in shell height was conducted in a cultured population of the Japanese scallop Patinopecten yessoensis. Applying the same selection intensity +/- 1.756 in upward and downward directions, three groups including two selected groups of Fast and Slow and one non-selected Control group were created, which were reared under the same environmental conditions at any stage. Differences always significantly existed among the three groups (P < 0.05), except for larvae at day 1 and at day 5, and in the order of Fast > Control > Slow. The average standardized response to selection (SR), realized heritability (h(R)2) and genetic gain (GG) was 0.473%, 0.269% and 7.85% for the Fast group and 0.381%, 0.217% and 6.60% for the Slow group respectively. Moreover, significant differences (P < 0.05) were detected between the fast and the slow lines in both SR and h(R)2, providing evidence for an asymmetric response in two directions. Performance in shell height is improved by 7.85% in the fast line after one generation selection, suggesting that mass selection for faster growth in a cultured population of the Japanese scallop is effective.

Subarachnoid haemorrhage (SAH):long-term cognitive outcome in patients treated with surgical clipping or endovascular coiling

Purpose: To compare long-term cognitive outcomes of patients treated with surgical clipping or endovascular coiling after subarachnoid haemorrhage (SAH). Method: Retrospective matched cohort study assessed neuropsychological functioning at least 12 months after aneurysmal SAH treatment. Fourteen patients treated by endovascular coiling and nine patients treated by surgical clipping participated. After gaining written consent, a comprehensive neuropsychological battery was completed. Standardised tests were employed to assess pre-morbid and current intellectual functioning (IQ), attention, speed of information processing, memory and executive function as well as psychosocial functioning and affect. Results: Treatment groups were not significantly different in terms of age, pre-morbid IQ, time from injury to treatment or time since injury. A significant effect of treatment on full-scale IQ score (p = 0.025), performance IQ (p = 0.045) and verbal IQ score (p = 0.029), all favouring the coiled group was observed. A medium effect size between groups difference in immediate memory (p = 0.19, partial ?(2) = 0.08) was also observed. No significant between group differences on attention, executive functioning and speed of information processing measures or mood and psychosocial functioning were noted. Both groups reported increased anxiety and memory, attention and speed of information processing deficits relative to normative data. Conclusions: Study findings indicate fewer cognitive deficits following endovascular coiling. Cognitive deficits in the clipped group may be due in part to the invasive nature of neurosurgical clipping. Further prospective research with regard to long-term cognitive and emotional outcomes is warranted. [Box: see text].
