    S obzirom na jednu od glavnih podjela paukova, skupina Mygalomorphae je zbog njihove skrovitosti, endemičnosti te slabo diferenciranih determinacijskih struktura slabije istražena nego skupina Araneomorphae. Iako nisu toliko mnogobrojni i raznoliki poput Araneomorphae, Mygalomorphae mogu dati uvid u evolucijski razvoj paukova upravo zbog njihove endemičnosti i specifičnosti. Za razliku od Araneomorphae koji imaju dobro razvijene mehanizme rasprostranjivanja, Mygalomorphae ostaju ''zaključani'' u svom izvorištu, te su kao takvi mnogo značajniji za razumijevanje evolucije pauka. U ovom radu opisana je skupina Mygalomorphae te njena pojavnost u Hrvatskoj, zajedno sa problematikom oko njene filogenije te determinacije rodova koji su prisutni u Hrvatskoj.Regarding one of the main classifications of spiders, taxon Mygalomorphae has not been studied as its counterpart taxon Araneomorphae due to its reclusiveness, poor differentation of morphological characteristics and the fact that large number of Mygalomorphae species are endemic. Although they’re not as numerous or diverse in species as Araneomorphae, Mygalomorphae can give us insight into the evolution of spiders precisely because of their reclusiveness and uniqueness. While Araneomorphae have effective mechanisms for dispersal, Mygalomorphae spiders tend to be ‘’locked up’’ in their centers of origin, thus being more significant in overall understanding of spider evolution. This paper presents overview of the main Mygalomorphae characteristics, as well as Mygalomorphae species of Croatia, along with the issue of their phylogeny, and problems that arise with their determination

    Taxon- and functional group-specific responses of ground beetles and spiders to landscape complexity and management intensity in apple orchards of the North China Plain

    Agricultural intensification has caused severe declines in ground-dwelling arthropods and associated ecosystem services. The conservation and re-establishment of semi-natural habitats in agricultural landscapes represent widely accepted measures to counter these declines. The effectiveness of these measures nonetheless varies between target taxa and their functional traits, while also being affected by local management. Here, we studied how species richness and abundance of different functional groups of carabid beetles and spiders in apple orchards were affected by landscape complexity (% semi-natural habitat) and local management intensity (mowing and soil total nitrogen (STN) content). Both abundance and species richness of non-carnivorous carabids and carabids overall were negatively affected by STN, while the abundance of carnivorous carabids and carabids overall was affected by interactive effects of mowing and landscape complexity, showing a positive response to mowing where semi-natural habitats are scarce, but negative responses in landscapes with a higher proportion of semi-natural habitats. The abundance of ground-hunting spiders and spiders overall was generally positively related to % semi-natural habitats, while the abundance of web-building spiders and the species richness of ground-hunting spiders showed a positive correlation with STN at landscapes with a low or medium abundance of semi-natural habitats, but a negative correlation where semi-natural habitats were more abundant. Non-carnivorous carabid diversity benefitted from low nitrogen application, while carnivorous carabid abundance benefitted from mowing intensity especially in simple and structurally homogenous agricultural landscapes. Both web-building and ground-hunting spiders positively responded to low nitrogen applications and intermediate landscape complexity. Overall, a low local management intensity promoted carabid beetles, while spiders were favored by increasing landscape complexity. We conclude that taxon- and functional group-specific, multi-scale conservation strategies are therefore required to conserve invertebrate predators in apple orchards

    Participação da criança e do adolescente na indústria do entretenimento com enfoque da Convenção da ONU dos Direitos da Criança e a efetividade do ECA

    O trabalho infantil artístico é uma das exceções entendidas pela OIT e pela Constituição Federal Brasileira à vedação do trabalho infantil, ao compreender que a atividade pode ser benéfica ao desenvolvimento da criança e por se tratar de um direito fundamental à cultura e à liberdade de manifestação artística. Todavia, apesar da relevância da necessidade de proteção da criança e do adolescente, no Brasil ainda não foi elaborada qualquer legislação que disponha sobre o procedimento e detalhamento dos deveres das produtoras para a obtenção da autorização judicial para a participação artística, dando a liberdade para que as portarias de cada comarca realizem tais previsões. A maior problemática dessa diversidade, além de violar a segurança jurídica das produtoras requerentes que não conseguem ter certeza das especificidades do procedimento a ser seguido, a necessidade de se atentar aos detalhes de cada comarca também prejudicam um controle para a proteção integral e a atuação em melhor interesse da criança e do adolescente. Com isso, o presente estudo propõe apresentar o cenário atual que se encontra o trabalho infantil artístico e o atual procedimento judicial para a obtenção da autorização judicial, ressaltando a sua necessidade de padronizaçãoArtistic child labor is one of the exceptions understood by the ILO and the Brazilian Federal Constitution to the prohibition of child labor, as it is understood that the activity can be beneficial to the development of minors and because it is a fundamental right to culture and freedom of artistic expression. However, despite the importance of the need to protect children and adolescents, no legislation has yet been drawn up in Brazil that provides for the procedure and details of producers' duties to obtain judicial authorization for artistic participation, leaving it up to the ordinances of each district to make such provisions. The biggest problem with this diversity is that, in addition to violating the legal certainty of requesting production companies, which are unable to be sure of the specifics of the procedure to be followed, the need to pay attention to the details of each district also undermines control for comprehensive protection and acting in the best interests of minors. This study aims to present the current scenario of artistic child labor and the current judicial procedure for obtaining judicial authorization, highlighting the need for standardizatio

    Sinopesa kumensis n. sp. (Arachnida, Araneae, Nemesiidae) est décrite de Kume-jima, une île à l’Ouest d’Okinawa (Japon). L’embolus du mâle est en forme de tire-bouchon, les réceptacles de la femelle sont bilobés. En comparaison avec S. maculata Raven &amp; Schwendinger, 1995 et S. guangxi Raven &amp; Schwendinger, 1995, les filières médianes sont présentes. En conséquence, la diagnose du genre Sinopesa est émendée.Sinopesa kumensis n. sp. (Arachnida, Araneae, Nemesiidae) is described from Kume-jima, an island West of Okinawa, Japan. Its male embolus is cork-screw-shaped, the female receptacula bilobed. Compared to S. maculata Raven &amp; Schwendinger, 1995 and S. guangxi Raven &amp; Schwendinger, 1995 from South-East Asia, the median spinnerets are present. For this reason the diagnosis of the genus Sinopesa requires emendation.</p
