Agradecimentos AGRADECIMENTOS Agradeço a Deus primeiramente por me fortalecer no dia a dia, por me capacitar a enfrentar os obstáculos e momentos difíceis da vida. Por me encorajar e estar ao meu lado na jornada que escolhi seguir e para a nova a qual Ele me guiará. E por acreditar e confiar que de alguma maneira está “olhando por mim”, me auxiliando a fazer as melhores escolhas para alcançar meus sonhos, objetivos e conquistas. Agradeço a minha mãe Adriana e o meu pai Cleber Cassiano por sempre estarem ao meu lado, pelo exemplo de pessoas de força, caráter, superação e fé. Vocês são inspiração para meu crescimento e amadurecimento pessoal, obrigada por transmitirem a mim valores tão preciosos, os quais me permitiram chegar até aqui! Obrigada pelo amor, paciência e por aceitarem as minhas escolhas. Ao meu irmão Lucas pelo companheirismo, risadas e momentos de distração. Eu amo muito vocês três!

Agradeço a todos pelo apoio, amor e carinho, enfim, toda a atitude e pensamentos positivos de vocês foram fundamentais para que eu chegasse até esta etapa da minha vida! Agradeço a minha amiga Manoela (Manu), pela amizade de anos, pelo carinho, troca de experiências e risadas, os nossos encontros são os melhores. Ao Julio pelo carinho e a amizade construída! Pela paciência, apoio e por me escutar sempre! E me fazer sorrir até nos momentos em que isso seria a última coisa que eu faria. Ao kenny pela amizade, conselhos e risadas! Maria Julia, Mitra e Letícia pela amizade mantida até hoje, mesmo que a distância.... Obrigada por vibrarem comigo a cada conquista e sempre torcerem pelo meu melhor! Sem dúvida vocês tiveram um papel fundamental neste percurso. Agradeço o meu orientador, Prof. Dr. Mario Sergio Palma, pela oportunidade, ensinamentos, orientação, e pelo exemplo de postura profissional e dedicação à pesquisa. Obrigada por nesses anos me ensinar o que é a ciência, para onde ela nos leva e quais são as responsabilidades quando decidimos e escolhemos seguir a carreira acadêmica, a qual representa “um universo” do prazer do conhecimento e aprendizagem, de mais perguntas do que respostas, de desafios e dificuldades, mas também de grandes oportunidades. Enfim, obrigada pela oportunidade cedida, por transferir a mim o conhecimento e amor pela ciência, pela paciência, e confiança em mim depositada. Muito obrigada!

Agradeço especialmente a todas as aranhas que foram utilizadas no presente estudo, em prol do conhecimento e desenvolvimento da ciência. “Um dia você aprende que o tempo não é algo que possa voltar para trás, e que não importa em quantos pedaços seu coração foi partido, o mundo não vai parar para que você o conserte. Portanto... plante seu jardim e decore sua alma, ao invés de esperar que alguém lhe traga flores. E você aprende que realmente pode suportar... que realmente é forte, e que pode ir muito mais longe depois de pensar que não se pode mais. E que realmente a vida tem valor e que você tem valor diante da vida! ” - Willian Shakespeare “Assim cada pessoa deixa sua marca em minha vida para sempre, umas porque me ajudam na construção, outras porque me apresentam projetos de sonho e outras ainda porque me desafiam a construí-los” (autor desconhecido modificado por Franciele).

Lockley Imported Fire Ant Station USDA-APHIS-PPQ 3505 25th Avenue Gulfport, Mississippi 39501 USA and G. B. Edwards Florida State Collection of Arthropods Division of Plant Industry Florida Dept. Agric. & Cons . Serv. P.O. Box 1269 Gainesville, Florida 32602 USA ABSTRACT Over a seven-year period, approximately 35,000 spiders representing 26 families, 133 genera, and 234 species were captured in Washington County, Mississippi, by pitfall, sweepnet, vacuum, bag, and hand. Specimens were collected in 10 different habitat types and in four vegetational strata . Old-field habitats yielded the most species (152) and residential lawns the fewest (14) . Considering all habitats sampled, the ground layer produced 111 species, the herbaceous strata 133, the shrub layer 49, and the tree strata 30 species . The sweepnet method of capture obtained 128 species, pitfall 95, hand 61, vacuum 53, and bagging 19 species. The largest number of species were obtained in spring and early summer (maximum of 125 in May), with the fewest in mid-winter (Jan . = 24) . Twenty-one species were considered abundant, 51 common, 67 uncommon, and 95 rare . Additions to the state list of Dorris (1972) number 102 species, for a new state total of 364 species . A comparison with the North American fauna and with other surveys indicates that Washington County is underrepresented both in cursorial forms active on the soil surface and web-spinning forms typical of undisturbed habitats .

  • Homeowner Guide to Scorpions and Their Relatives
    HOMEOWNER Guide to by Edward John Bechinski, Dennis J. Schotzko, and Craig R. Baird CIS 1168 Scorpions and their relatives “Arachnid” is the scientific classification category for all eight-legged relatives of insects. Spiders are the biggest group of arachnids, with nearly 3800 species known from the U.S and Canada. But the arachnid category includes other types of eight-legged creatures that sometime cause concern. Some of Idaho’s non-spider arachnids – such as scorpions -- pose potential threats to human health. Two related non-spider arachnids – sun scorpions and pseudoscorpions – look fearsome but are entirely harmless. This publication will help you identify these three groups and understand the threats they pose. All three of these groups almost always are seen as lone individuals that do not require any control.
