Assessing the conservation status of the strict endemic Desertas wolf spider, Hogna ingens (Araneae, Lycosidae)

The Desertas Islands (Madeira, Portugal) are the sole home of one of the largest and rarest wolf spiderspecies, Hogna ingens (Blackwall 1857) (Araneae, Lycosidae). Despite its size, it inhabits a single valleyin the North of the Deserta Grande Island, Vale da Castanheira, currently invaded by the herb Phalarisaquatica. This invasive species competes with the native flora and was subject to several eradicationexperiments, namely through fire and chemicals. The objectives of this work were to: (1) estimate thecurrent distribution and abundance of H. ingens and respective trends; (2) evaluate the impact of theinvasive plant and eradication methods on the spider population; (3) suggest future measures for therecovery of the species; and (4) evaluate its conservation status according to the IUCN criteria. The current distribution of H. ingens covers 23 ha, a recent reduction from its original 83 ha, correspond-ing to the entire Vale da Castanheira. A total of 4447 and 4086 adults and 71,832 and 24,635 juvenileswere estimated to live in the valley during 2011 and 2012, respectively. We found a significant negativeimpact of P. aquatica cover on the presence and abundance of H. ingens and that chemical treatmentspecifically directed towards the invasive plant species may be the only way to effectively recover thespider's habitat. We suggest (1) regular monitoring; (2) extend chemical treatments; (3) ex-situ conserva-tion with future reintroduction of adults. Based on the current area of occupancy (AOO) of H. ingens and itsrecent decline in both AOO and number of individuals, it was recently classified as Critically Endangeredby IUCN and we suggest its urgent inclusion in the Habitats Directive species lists.

A indisciplina nas aulas de Educação Física : crenças de professores e de alunos : um estudo nas escolas dos Açores

[…]. Este livre que agora se publica resulta de mais uma tentativa de compreensão de factores subjacentes as situações de disciplina/indisciplina. Centra-se na óptica dos intervenientes, isto é, professores e alunos, e contém duas particularidades: a de procurar aduzir razões interpretativas da indisciplina no contexto da Educação Física e a de corresponder a um levantamento da situação num ambiente insular cuja descontinuidade territorial separa não só a Região Açores do continente português, mas também as diferentes ilhas que integram o Arquipélago. Pretende, então, neste contexto, fazer emergir informação fundamentada e circunstanciada sobre a temática, para que possa vir a ser utilizada no desenvolvimento da profissionalidade e do profissionalismo docentes e na educação para o bem-estar, para o desporto e para a cidadania dos jovens, em particular dos jovens açorianos. Resulta do esforço e do empreendimento de Isabel Condessa, especialista em Metodologia do Ensino da Educação Física, em colaboração com Isabel Estrela Rego e Suzana Nunes Caldeira, ambas especializadas em Psicologia da Educação.

Students' engagement in schools : differentiation and promotion

The objective of this work is to present elements of the project Student engagement in Schools (SES). The team consists of 10 researchers from six Universities. Student engagement in schools is a multidimensional construct that unites affective, behavioural, and cognitive dimensions of student adaptation in the school and has influence on students’outcomes. The team of researchers conceptualized two major studies, a differential study to analyze the relations between SES and contextual factors, personal factors, student’s outcomes, and a quasi-experimental study to analyze the effects on SES of a specific intervention programmes. In study 1, the sample size is around 600 students (150 6th graders, 150 7th graders, 150 9th graders, and 150 10th graders). We shall focus on years of school transition, with rural and urban populations, on different regions of the country, and on students with different family background. We shall conduct questionnaires with national and international scales. The study 2 will involve students in 7th and 9th grade, from four classes, two of the experimental group and two of the control group. Patterns of verbal communication between a teacher and students can influence the classroom environment and SES. This model of communication would result in more effective student management and more time on-task for learning.
