“…Os nitidulídeos são os principais polinizadores das anonáceas cultivadas, como a pinha e graviola (Nadel & Peña, 1994), e a maioria dos autores descreve essa família como uma das mais frequentes na polinização de palmeiras (Küchmeister et al, 1998). Além de anonáceas silvestres, ocorrem também palmeiras na FLONA Araripe.…”

Composition of entomofauna on the Araripe National Forest in different vegetation types and year seasonsThe occurrence of insects has great ecological significance and is related to environmental factors, food availability, and refuge. We assess the composition of the entomofauna in different vegetation types (cerrado, carrasco and humid forest), and seasons in the Araripe National Forest, Crato-CE, by weekly collections made in the dry season (September to December) and in the rainy season (April to July), through McPhail, pitfall and yellow tray traps. Many Coleoptera occur in the dry season, acting as pollinators, phytophagous, detritivore and decomposers of organic matter in the rainy season. Already, the Diptera is abundant in the rainy season, when fruit flies are found, decomposing animal carcasses, organic matter and predators. The Calliphoridae family predominate in the Cerrado, the Tachinidae in the Carrasco and Tephritidae in the Humid Forest. The Orthoptera Gryllidae predominate in the Humid Forest and the Hymenoptera Formicidae in the Carrasco and Cerrado in the dry season. Therefore, there is a satisfactory balance in the structure and functioning of the Araripe National Forest as each group plays an important ecological role on the vegetation, in the different seasons of the year. Composição da entomofauna da Floresta Nacional do Araripe em diferentes vegetações e estações do anoA ocorrência de insetos tem grande significado ecológico e está relacionada com os fatores ambientais, disponibilidade de alimento e abrigo. Para avaliar a composição da entomofauna, em diferentes tipos de vegetação (Cerrado, Carrasco e Mata Úmida) e estações do ano na Floresta Nacional do Araripe, Crato, Ceará, nordeste brasileiro, foram realizadas coletas semanais na estação seca (setembro a dezembro) e chuvosa (abril a julho), por meio de armadilhas McPhail, de solo e bandejas amarelas. Os insetos da ordem Coleoptera são numerosos, na estação seca, agindo como polinizadores, fitófagos e detritívoros, além de decompositores de matéria orgânica, na estação chuvosa. Os Diptera são numerosos na estação chuvosa, quando são encontradas moscas frugívoras, decompositoras de carcaças de animais, de matéria orgânica e predadoras; os da família Calliphoridae predominam no Cerrado; da família Tachinidae, no Carrasco, e da Tephritidae, na Mata Úmida. Os Orthoptera Gryllidae predominam na Mata Úmida e os Hymenoptera Formicidae, no Carrasco e Cerrado na estação seca. Portanto, cada grupo de insetos desempenha um papel ecológico sobre as vegetações, nas diferentes estações do ano.Palavras-chave: biodiversidade, indicadores ecológicos, ecossistemas, insetos florestais.

The candidate confirms that the work submitted is her own and that appropriate credit has been given where reference has been made to the work of others. i ACKNOWLEDGEMENTSThe first thanks must go to the National Environment Research Council, who were kind enough to fund the first three years of this project. My supervisors Oliver Phillips and Alan Grainger deserve the strongest possible thanks for all their ideas, feedback and support. Thanks too to Steve Carver, a helpful member of the supervisory team in the first phase of the project. I am grateful for the constructive criticism of RSG members Mike Kirkby and Steve Compton.On the climate modelling side, Richard Betts and Peter Cox from Hadley Centre were supportive with advice, elucidation and most importantly, climate change scenario outputs. In the standard impact scenario (SIS), future population processes are simulated over 100 years, with changes in the variables governing cell suitability being applied annually according to anomalies from a selected GCM. The run is repeated for each species using anomalies of half that magnitude, as a reduced-impact scenario (RIS).

“…Insects, particularly dung beetles of the subfamily Scarabaeinae (Coleoptera, Scarabaeidae), play an important ecological role in several biological processes occurring in terrestrial environments (NICHOLS et al 2008), such as the control of some vertebrate parasites (BORNEMISSZA 1970, KLEIN 1989, FLECHTMANN et al 1995, soil bioperturbation and pollination (KÜCHMEISTER et al 1998, SAKAI & INOUE 1999, seed dispersal (FEER 1999, ANDRESEN 2002, and nutrient cycling (GUERRA et al 2007).…”

ABSTRACT. The study was conducted at the Mata dos Godoy State Park in Londrina, state of Paraná, Brazil. Baited pitfall traps were installed in the forest, in adjacent abandoned pasture land, and on the borders between these two environments. Every two weeks, from June 1999 to May 2000, the traps were placed for 24 hours and the material was collected every 12 hours. The 4687 specimens of Scarabaeinae collected belong to 13 genera and 27 species. The most frequent were different. Sulcophanaeus menelas, Canthidium aff. trinodosum, O. hirculus, and E. parallelus were the most abundant species, being predominantly diurnal; the first three species were more active on abandoned pasture. Most of the Dichothomius assifer (Eschscholtz, 1822) and D. mormon specimens were captured at night. The latter species was the most abundant in edges, whereas D. assifer, Scybalochantum aff. zischkai, and O. catharinensis can be considered bioindicators because they were either exclusively or highly predominant in the best preserved areas. A larger number of individuals was observed from December 1999 through March 2000, which is the time of the year when adults of Scarabaeinae normally emerge and fly, in the studied region. The highest diversity (88.89%) was observed in February.
