Estimating the prevalence of unregistered driving in Queensland. Report to Queensland Department of Transport and Main Roads

A state-wide observational study was undertaken by the Centre for Accident Research and Road Safety – Queensland (CARRS-Q) in order to investigate the prevalence of unregistered vehicles on Queensland roads. This study was conducted on behalf of the Queensland department of Transport and Main Roads (TMR). This study builds upon research commissioned by Queensland Transport and conducted in 2000, 2003 and 2005. Vehicles were observed throughout Queensland from April 13th, 2010 to May 8th, 2010 in a mix of small rural towns, regional centres and metropolitan locations. The locations sampled for this study were restricted to destinations (e.g. shopping centres, hospitals, airports and park-and-ride facilities) rather than residential areas, and a variety of different destinations were sampled. Sampling vehicles in these types of locations provides a higher probability that the vehicles captured in the survey are being driven on a regular basis (Younglove, et al. 2004).

Affordances of ICTs: an environmental study of a French language unit offered at university level

This project investigates the integration of Information Communication Technologies (ICTs) into educational settings by closely looking at the uptake of the perceived affordances offered by ICTs by students enrolled in a French language course at Queensland University of Technology. This cross-disciplinary research uses the theoretical concepts of: Ecological Psychology (Gibson, 1979; Good, 2007; Reed, 1996); Ecological Linguistics (Greeno, 1994; Leather & van Dam, 2003; van Lier 2000, 2003, 2004a, 2004b); Design (Norman, 1988, 1999); Software Design/ Human-Computer Interaction (Hartson, 2003; McGrenere & Ho, 2000); Learning Design (Conole & Dyke, 2004a, 2004b; Laurillard et al. 2000;); Education (Kirschner, 2002; Salomon, 1993; Wijekumar et al., 2006) and Educational Psychology (Greeno, 1994). In order to investigate this subject, the following research questions, rooted in the theoretical foundations of the thesis, were formulated: (1) What are the learners’ attitudes towards the ICT tools used in the project?; (2) What are the affordances offered by ICTs used in a specific French language course at university level from the perspective of the teacher and from the perspective of language learners?; (3) What affordances offered by ICT tools used by the teacher within the specific teaching and learning environment have been taken up by learners?; and (4) What factors influence the uptake by learners of the affordances created by ICT tools used by the teacher within the specific teaching and learning environment? The teaching phase of this project, conducted between 2006 and 2008, used Action Research procedures (Hopkins, 2002; McNiff & Whitehead, 2002; van Lier 1994) as a research framework. The data were collected using the following combination of qualitative and quantitative methods: (1) questionnaires administered to students (Hopkins, 2002; McNiff & Whitehead, 2002) using Likert-scale questions, open questions, yes/no questions; (2) partnership classroom observations of research participants conducted by Research Participant Advocates (Hopkins, 2002; McNiff & Whitehead, 2002); and (3) a focus group with volunteering students who participated in the unit (semi-structured interview) (Hopkins, 2002; McNiff & Whitehead, 2002). The data analysis confirms the importance of a careful examination of the teaching and learning environment and reveals differences in the ways in which the opportunities for an action offered by the ICTs were perceived by teacher and students, which impacted on the uptake of affordances. The author applied the model of affordance, as described by Good (2007), to explain these differences and to investigate their consequences. In conclusion, the teacher-researcher considers that the discrepancies in perceiving the affordances result from the disparities between the frames of reference and the functional contexts of the teacher-researcher and students. Based on the results of the data analysis, a series of recommendations is formulated supporting calls for careful analysis of frames of reference and the functional contexts of all participants in the learning and teaching process. The author also suggests a modified model of affordance, outlining the important characteristics of its constituents.

Late results after paediatric cardiac surgery

Background: Congenital heart defects include a wide range of inborn malformations. Depending on the defect, the life expectancy of a newborn with cardiac anomaly varies from a few days to a normal life span. In most instances surgery, is the only treatment available. The late results of surgery have not been comprehensively investigated. Aims: Mortality, morbidity and the life situation of all Finnish patients who had been operated on for congenital heart defect during childhood were investigated. Methods: Patient and surgical data were gathered from all hospitals that had performed heart surgeries on children. Late mortality and survival data were obtained from the population registry, and the causes of deaths from Statistics Finland. Morbidity of patients operated on during 1953-1989 was assessed by the usage of medicines. The pharmacotherapy data of patients and controls were obtained from the Social Insurance Institute. The life situation of patients was surveyed by mailed questionnaire. Survival, causes of deaths and life situation of patients were compared with those of the general population. Results: A total of 7240 cardiac operations were performed on 6461 children during the first 37 years of cardiac surgery (1953-1989). The number of procedures constantly rose during this period, and the increase continued in later years. The patient material varied over time, as more defects became surgically treatable. During 1953-1989 the operative mortality (death within 30 days of surgery) was 6.9%. In the 1990s a slight rise occurred in early mortality, as increasingly complicated patients were surgically treated. During 2000-2003 practically no defects were beyond the operative range. Thus, the operative mortality of 4.4% was excellent, decreasing even further to 2.0% in 2004-2007. The overall 45-year survival of patients operated on in 1953-1989 was 78%, and the corresponding figure for the general population was 93%. Survival depended on the defect, being worst among patients with univentricular heart. Late survival was also better during the 1990s and at the beginning of the 21st century. Of the 6028 early survivors, 592 died late (>30 days) after surgery. A total of 397 deaths (67%) were related and 185 (31%) unrelated to congenital heart defect. The cause of death was unknown in 10 cases. Of those 5774 patients who survived their first operation and had complete follow-up, 16% were operated on several times. Seventeen percent of patients used medicines for cardiac symptoms (heart failure, arrhythmia, hypertension and coronary disease). Patients risk of using cardiac medicines was 2.16 (Cl 1.97-2.37) times higher than that of controls. Patients also had more genetic syndromes and mental retardation and more often used medicines for asthma and epilepsy. Adult patients who had been operated on as children had coped surprisingly well with their defects. Their level of education was similar and their employment level even higher than expected, and they were living in a steady relationship as often as the general population. Conclusions: Cardiac surgery developed rapidly, and nowadays practically all defects can be treated. The overall survival of all operated patients was 78%, 16% less than that of the general population. However, it was significantly better than the anticipated natural survival. However, many patients had health problems; 16% needed reoperations and 17% cardiac medicines to maintain their condition. Most of the patients assessed their general health as good and lived a normal life.

Long-term effects of physical activity level on changes in healthy body mass index over 12 years in young adult women

Objectives To examine the effects of overall level and timing of physical activity (PA) on changes from a healthy body mass index (BMI) category over 12 years in young adult women. Patients and Methods Participants in the Australian Longitudinal Study on Women's Health (younger cohort, born 1973-1978) completed surveys between 2000 (age 22-27 years) and 2012 (age 34-39 years). Physical activity was measured in 2000, 2003, 2006, and 2009 and was categorized as very low, low, active, or very active at each survey, and a cumulative PA score for this 9-year period was created. Logistic regression was used to examine relationships between PA accumulated across all surveys (cumulative PA model) and PA at each survey (critical periods PA model), with change in BMI category (from healthy to overweight or healthy to obese) from 2000 to 2012. Results In women with a healthy BMI in 2000, there were clear dose-response relationships between accumulated PA and transition to overweight (P=.03) and obesity (P<.01) between 2000 and 2012. The critical periods analysis indicated that very active levels of PA at the 2006 survey (when the women were 28-33 years old) and active or very active PA at the 2009 survey (age 31-36 years) were most protective against transitioning to overweight and obesity. Conclusion These findings confirm that maintenance of very high PA levels throughout young adulthood will significantly reduce the risk of becoming overweight or obese. There seems to be a critical period for maintaining high levels of activity at the life stage when many women face competing demands of caring for infants and young children.

Open Access -julkaiseminen, linkittäminen ja tekijänoikeus - selvitys verkkojulkaisusopimuksissa huomioitavista seikoista

Kirjastoissa ja yliopistoissa tapahtuvaa tieteellisten töiden verkkokäyttöä koskevat tekijänoikeudelliset kysymykset ovat viimeaikoina aiheuttaneet päänvaivaa. Tietoverkot ja digitaalinen ympäristö muodostavatkin tekijänoikeuden kannalta erityisen soveltamisympäristön johon perehtyminen edellyttää tarkempaa tietämystä tiedon siirtämisestä, tietokannoista sekä ylipäätään tietoverkkoihin liittyvistä teknisistä toiminnoista. Koska sovelletut tekniset ratkaisut poikkeavat eri yhteyksissä toisistaan, pyrin kirjoituksessa yleisellä tasolla selvittämään niitä käyttäjien ja oikeudenhaltijoiden välisiä tekijän- ja sopimusoikeudellisia kysymyksiä, joita teosten käyttö tietoverkoissa aiheuttaa. Pyrkimyksenä on tuoda esiin ne tekijänoikeudellisesti merkitykselliset seikat, jotka verkkojulkaisuja arkistoitaessa, välitettäessä sekä linkkejä käytettäessä tulisi alkuperäisten tekijöiden, kustantajien ja verkkojulkaisijoiden (esimerkiksi kirjasto tai yliopisto) välisissä sopimuksissa ottaa huomioon. Kysymyksiä tarkastellaan erityisesti julkaisijan näkökulmasta. Esitys sisältää myös kustantajien lupakäytäntöä käsittelevän empiirisen tutkimuksen. Tutkimuksessa on tarkasteltu kuinka usein kustantajat ovat vuosien 2000 – 2003 välisenä aikana myöntäneet luvan julkaista väitöskirjan artikkeli osana väitöskirjaa Teknillisen korkeakoulun avoimella ei kaupallisella www-palvelimella. Koska linkeillä on verkkojulkaisutoiminnassa usein merkittävä rooli, mutta niiden tekijänoikeudellinen asema on epäselvä, kirjoituksen jälkimmäisessä osiossa perehdytään linkkien tekijänoikeudelliseen asemaan.

Alternativas de alimentación bovina implementados en época seca, en el municipio de Palacagûina, Madriz, 2014

Este trabajo se realizó en el Municipio de Palacagüina, departamento de Madriz, con el propósito de identificar estrategias de alimentación bovina en época seca. Para ello se tomó una muestra aleatoria de 40 productores (8% de la población existente), con una tipología de pequeña y mediana ganadería. La información de campo se recolectó mediante la ejecución de entrevistas dirigidas a productores/as que se dedican a la producción de leche y carne. La metodología utilizada es la de estudio de casos, donde se analiza una problemática específica, en este caso las diversas estrategias de alimentación del ganado bovino durante la época seca. Los aspectos a considerar fueron los componentes del sistema alimenticio como son agua, energía, proteína, vitaminas y minerales, además se consideraron aspectos sanitarios, genéticos reproductivos y de comercialización de los productos pecuario (leche y carne). La información se colecto a través de entrevistas directas a los productores y se procesó haciendo uso de la estadística descriptiva, siendo analizada en el programa computarizado SPSS (Programa Estadística para Ciencias Sociales). Se encontró que el sistema de alimentación predominante en la zona es el de pastoreo. Que los componentes del sistema de pastoreo (agua, energía, proteína, vitaminas y minerales), aun cuando todos están presentes en la dieta de los animales, deben ser evaluados en función de su optimización, para obtener una mejor producción ganadera. Los productores de la zona requieren de capacitación en materia de alimentación y nutrición animal para que conozcan mejor las necesidades que tienen los animales y así puedan trabajar más eficiente en la producción ganadera, sobre todo con el potencial genético con que cuentan en la zona.

Este trabajo presenta el análisis de la satisfacción vital expresada por un grupo de madres jóvenes inmigrantes al frente de familias monomarentales usuarias del Programa Beregain de la Fundación Itaka-Escolapios (Bilbao). Se realizaron entrevistas individuales semiestructuradas a las madres que integran la muestra. El análisis e interpretación de datos se llevaron a cabo conforme a una metodología cualitativa, específicamente el estudio de casos. Los resultados revelaron la escasa satisfacción en ciertos ámbitos vitales relacionados con las relaciones interpersonales, el ocio, la conciliación del cuidado de sus hijos/as con la propia formación, y la imposibilidad de hacer frente a los gastos económicos sin la ayuda que reciben por parte de la fundación.

Sobrevida e fatores prognósticos para o câncer de mama em Juiz de Fora, Minas Gerais, na coorte diagnosticada entre 1998 e 2000

Este estudo teve como objetivo analisar a sobrevida e fatores prognósticos para o câncer de mama feminino, com ênfase no papel de variáveis relacionadas aos serviços de saúde. Foram analisadas 782 mulheres com câncer invasivo da mama e submetidas à cirurgia curativa, que realizaram tratamento cirúrgico e/ou terapia complementar no município de Juiz de Fora, Minas Gerais, com diagnóstico da doença entre 1998 e 2000. O recrutamento dos casos foi efetuado a partir de busca ativa nos registros médicos de todos os serviços de saúde que prestam atendimento em oncologia na cidade. O seguimento foi realizado mediante retorno aos prontuários e complementado por busca no banco do Sistema de Informação sobre Mortalidade (SIM), contato telefônico e consulta de situação cadastral no Cadastro de Pessoas Físicas (CPF). As principais variáveis analisadas foram: cor da pele, idade ao diagnóstico, tamanho do tumor, comprometimento de linfonodos, estadiamento, cidade de residência e variáveis relativas aos serviços de saúde, entre outras. As funções de sobrevida foram calculadas por meio do método de Kaplan-Meier. Foi utilizado o modelo de riscos proporcionais de Cox para avaliação dos fatores prognósticos. No primeiro artigo, foi observada taxa de sobrevida específica em cinco anos de 80,9%, sendo identificados tamanho tumoral e comprometimento de linfonodos axilares como importantes fatores prognósticos associados de forma independente à sobrevida pela doença na população de estudo (HR=1,99, IC95%: 1,27-3,10 e HR=3,92, IC95%: 2,49-6,16, respectivamente). No segundo artigo, quando consideradas as variáveis relativas aos serviços de saúde, foi verificada pior sobrevida para as mulheres assistidas no serviço público, embora com significância limítrofe (p=0,05), e para aquelas que não tinham plano privado de saúde, apesar de não significativa (p=0,1). As funções de sobrevida não ajustadas e estratificadas por natureza do serviço de saúde exibiram sobrevida mais desfavorável para as mulheres não brancas e para os casos com nenhum ou menos de 10 linfonodos isolados somente no serviço público, embora com significâncias estatísticas apenas marginais (p=0,09 e p=0,07, respectivamente). Na análise multivariada, foi observado maior risco de óbito nas mulheres que não fizeram uso de hormonioterapia apenas para os casos assistidos no serviço público (HR=1,56; IC95%: 1,01-2,41), independentemente do tamanho tumoral e do status ganglionar axilar. Tais achados sugerem desigualdades sociais e disparidades na prevenção primária e secundária da doença na região estudada, com desvantagem para o serviço público de saúde, enfatizando a maior necessidade de esclarecimento sobre a doença, assim como de diagnóstico e tratamento dos casos em estádios mais precoces. Destacou-se, ainda, o valor de se trabalhar com informações produzidas pelos serviços de saúde responsáveis pela assistência oncológica no país, possibilitando a caracterização do perfil e da sobrevida das pacientes assistidas e fornecendo subsídios aos órgãos competentes do setor saúde local para nortear a adoção de estratégias de prevenção direcionadas ao controle da doença na população avaliada.

O Instituto Federal de Educação, Ciência e Tecnologia de Mato Grosso: memórias e representações sociais

O estudo teve por objetivo identificar e analisar as memórias e representações sociais acerca do Instituto Federal de Educação, Ciência e Tecnologia de Mato Grosso (IFMT) construídas por seus docentes, servidores técnico-administrativos e alunos. Os pressupostos teóricos sobre os quais a pesquisa se assenta estão centrados em um diálogo entre aqueles da teoria das representações sociais e os que presidem os estudos da memória social numa perspectiva psicossocial. As representações sociais são exploradas tomando-se como principais autores de referência Moscovici (1978, 2003) e Abric (1998, 2000, 2003), enquanto a memória é tratada em seu aspecto coletivo/social, recorrendo-se a autores como Halbwachs (1994, 2004), Barlett (1995) e Sá (2005, 2007). Para a coleta dos dados foram utilizadas as técnicas de evocações livres e de entrevistas semi-estruturadas. Participaram das evocações 260 sujeitos, sendo 100 docentes, 60 técnico-administrativos e 100 discentes. Desse total, foram selecionados 58 sujeitos para participarem das entrevistas. O material coletado por meio das evocações foi processado pelo software EVOC (2003) e o referente às entrevistas pelo software ALCESTE. Os resultados revelaram que a memória socialmente construída acerca do IFMT quando ainda era Escola Técnica Federal (ETFMT) tende nitidamente para o pólo positivo de avaliação e as representações que consubstanciam essa memória têm relação com a qualidade da educação ali ofertada. Foi também possível evidenciar diferenças entre as representações construídas pelos três grupos de sujeitos. De outra parte, os resultados referentes às representações sociais contemporâneas, que têm como objeto o IFMT e o imediatamente anterior Centro Federal de Educação Tecnológica (CEFETMT), revelam a presença de elementos de avaliação negativa em sua composição. A formação profissional ainda é vista como positiva e de qualidade pelo grupo de alunos, mas esse mesmo elemento, qualidade, perde a centralidade nas representações dos docentes e dos técnico-administrativos. De modo geral, os resultados apontam para representações sociais díspares entre os três grupos. A negatividade identificada na estrutura representacional do IFMT no presente parece estar associada às transformações pelas quais a instituição passou ao longo das últimas décadas, devido às políticas públicas impostas pelo governo para as instituições que compõem a rede federal de educação profissional. Com base nesses resultados, chegou-se à conclusão quanto à existência de memórias e representações distintas entre os docentes, discentes e técnico-administrativos acerca do passado e do presente da instituição.

香港地区湍蛙遗传多样性研究

依据线粒体上ND2和CO1两个变异较大的基因序列分析了香港地区香港湍蛙7种群、华南湍蛙1种群，以及大陆其他地区华南湍蛙7种群，戴云湍蛙1种群，武夷湍蛙1种群的系统发育关系，进而探讨香港湍蛙的遗传多样性、香港湍蛙特有性、如何确定香港湍蛙最佳保护单元以及这四种湍蛙的物种分类地位。 1． 香港湍蛙保护遗传学研究 香港湍蛙核苷酸传多样性较低，从其遗传多样性信息、单倍型网络分析、中性检验值以及岐点分布结果一致显示香港湍蛙很可能经历了瓶颈后的扩张，种群正在由一个较小的有效种群大小迅速增长, 有足够的时间通过变异用于积累单倍型的多态性, 而对于提高核苷酸多样化而言, 时间尚短（Nei M et al，1975，Avise J C，2000；李明等，2003）。 分子变异分析结果显示香港湍蛙种群间存在较多的基因交流，且系统发育树上各种群间交叉在一起，没有形成与地理单元相关的分支，而从其单倍型网络看，他们源于共同的祖先，是一个单系群，与地理单元间没有形成显著的遗传分化。因此应作为一个进化显著单元（ESU）。结合其与其他湍蛙发育关系及遗传距离以及野外采集信息认为香港湍蛙只在香港地区有分布，属于香港特有种。该物种内遗传多样性较低，又属于世界自然保护联盟红皮书中的近危种，同时也是《野生动物保护条例》中的受保护野生动物，且由于香港城市建设等使得其栖息环境受到威胁，因此在香港特别行政区应该受到重点保护。 从单倍型分布和核苷酸多样性可以看出大榄涌种群和城门种群具有较高的单倍型多样性和核苷酸多样性，应该作为保护的重点区域。 2. 华南湍蛙东、南沿海种群间系统关系 华南湍蛙分布广，各种群存在着丰富的遗传多样性信息且中部种群广西龙胜和湖南张家界种群核苷酸多样性明显高于其他边缘种群华南湍蛙。种群间几乎没有基因交流，且各种群间无共享单倍型，可见已形成了显著的遗传分化。各种群间遗传距离都较远，其中广东南昆山种群以及福建三港种群与其他种群距离最远，因此可以推测其他种群（广东深圳、香港大屿山、广西龙胜和防城以及湖南张家界种群）可能为独立进化的种群。但是否是一新种或一隐存种，还需要结合形态学进行更深入的研究。 本研究中无论从系统关系看还是从遗传距离看，大屿山种群与深圳种群最近，支持陈坚峰等将其定为华南湍蛙，即华南湍蛙新增一个分布点：香港大屿山。 系统树上广西防城种群（支B）与龙胜和湖南种群（支A）形成姐妹群。香港大屿山种群与深圳种群先形成姐妹群（支C），但却没有与其距离很近的广东南岭及南昆山种群（支D）形成姐妹群，可能粤北和粤中的环境及气候较复杂因此与粤南其他种群形成了明显的隔离。同时可以看出华南湍蛙种群遗传分化与地理距离没有显著的相关性。 3. 四种湍蛙间的系统关系 根据线粒体CO1基因建立四种湍蛙间的系统关系及其遗传距离，很清楚地看到，香港湍蛙与戴云湍蛙关系很近，而华南湍蛙则与武夷湍蛙较近。然而，戴云湍蛙同一个种群内部共有两个单倍型DY1和DY2，且两个单倍型间遗传距离大于DY1与香港湍蛙间遗传距离，更远远大于香港湍蛙种群内部的距离，即戴云湍蛙内部两个单倍型间遗传距离达到了种级水平，同样在系统发育树上这两个单倍型与香港湍蛙形成并系。但是，戴云湍蛙种内在形态上差异不显著。因此，其是否属于萌芽物种分化形成（budding speciation）或已经完全分化为两个不同的种值得进一步研究？ 与戴云湍蛙香港湍蛙关系类似，从系统树上看华南湍蛙不形成单系，而是分成两个大支，与武夷湍蛙形成并系，且福建和南昆山的华南湍蛙与武夷湍蛙遗传距离远大于武夷湍蛙种内福建种群与浙江种群的遗传距离，达到了种级分化水平。由此，可以推断武夷湍蛙是有效种。系统树上广东深圳、香港大屿山、广西防城和龙胜以及湖南张家界种群与华南湍蛙福建及南昆山各种群间遗传距离已超出了种内各种群间的遗传距离，但是至于这一支是否应为另外一个种，有必要扩大采样，并结合核基因及形态信息进行进一步研究。 MtDNA of ND2 and CO1 gene were used to investigate genetic diversity of Amolops in Hongkong .We collected seven populations of A. hongkongensis,，one population of A.ricketti from Hong Kong and other seven populations of A.ricketti from East and South of Chinese mainland. As well as one population of A. daiyunensis and one population of A.wuyiensis Phylogenetic relationship were analyzed of four species. Discussed whether A.hongkongensis is an endemic species and how can we make the conservation and management decisions. 1. Conservation Genetics of A. hongkongensis A. hongkongensis has a low nucleotide diversity, the results of genetic diversity, haplotype network, neutrality test and the mismatch distributions indicate that A. hongkongensis experienced a recent expansion after a bottle neck. They had enough time to accumulated haplotype diversity, but it’s too short to have a high nucleotide diversity（Nei M et al，1975，Avise J C，2000；Li et al，2003）. The result of AMOVA reveals that it has much gene exchange among the populations of A. hongkongensis. The clades of the phylogenetic tree were mixed together, no significant genetic differentiation among 8 populations and they share the same ancestor from the network analysis, these indicate that they are monophyly and should be protected as one ESU. Combined with the information of relationships of interspecies, genetic distance and distribution investigate, We conclude that A. hongkongensis is an endemic species of Hong Kong. Considering on the status of low genetic diversity in A.hongkongensis, and this species was listed in the IUCN red list as near threatened, as well as listed in the . Furthermore, it’s habitat loss and degradation more rapidly as the human activity got higher and higher. So it’s urgent to protect them in Hong Kong. Our results suggest that Tai Lam Wu and TAI MO Shan -Shing Mun populations have the higher priority to be protected because their higher genetic diversity. 2．Phylogenetic relationships among populations of Amolops ricketti from the Southern and eastern China A. ricketti has the considerable genetic diversity of mitochondrial haplotypes within and among populations, and Mitochondrial DNA diversity was higher in populations at the central area of the present distribution range of the frog，i. e. the Longsheng population and Zhangjiajie population, than at the edges of their distribution range. They have no share haplotype among populations, and have a significant genetic differentiation. Genetic distance is high among the populations, especially the distance of Nankun and Sangang group with others, which suggested that they evolved independently. May be there is a cryptic species or a new species, a further study is needed. The results of gene tree and the genetic distance clearly demonstrate that the population from LanTau island is A. ricketti, so we agree with Chen et al(2005) . That means A.ricketti have a new distribution site: LanTau island, HongKong. Phylogenetic relationships were analyzed through NJ and Mrbayes methods and got a consistent topological structure, the structure indicated that the ingroup were comprised four groups. Populations Longsheng and Zhangjiajie were first clustered as clade A; Populations Fangcheng was clustered together (clade B) as a sister group to clade A；Populations Shenzhen and Lantau island were sister groups and clustered as clade C；Then the clade D included populations Nankunshan and Nanling in Guangdong province and Sangang in Fujian province. 3. Phylogenetic Relationships among these four specises Phylogenetic relationships based on 1503bp CO1 gene and the genetic distance show that A. hongkongensis close to A. daiyunensis whereas A.ricketti near to A.wuyiensis. Nevertheless, there are two haplotypes in A.daiyunensis and the genetic distance between them higher than the distance between DY1 with A. hongkongensis. A. hongkongensis is nested in the paraphyletic ancestral species A. daiyunensis. Without significant difference in the morphological characters, So, we considered both A.daiyunensis and A.hongkongensis are valid species, may be this represents a case of ‘budding speciation’ like Batrachuperus pinchonii(Fu and Zeng,2008) in the population of A. daiyunensis. Just like two species above A. wuyiensis and A. ricketti are not monophyly, instead, A.wuyiensis is nested in the paraphyletic ancestral species A.ricketti. We need do more research to make sure whether they are new species.
