“…On the other hand, zoochoric species are prevalent in all the habitats of a rainforest (Yamamoto et al 2007). There is a predominance of zoochorous trees and shrubs in tropical forests (Roth 1987;Negrelle 2002;TetetlaRangel et al 2013) and seasonal rainforests (Ortega 1986;Kinoshita et al 2006).…”

Pollination and dispersal are critical ecological processes that directly affect the reproductive success of plants and are important for understanding the structure of plant communities. We compiled data on pollination and dispersal syndromes of 406 plant species distributed among different elevations in Área de Proteção Ambiental da Serra de Baturité (APASB) in northeastern Brazil. We aim to determine how the dispersal and pollination of the flora in the mountainous rainforest of APASB are affected by climate, relief and growth form. We hypothesized that plant community is comprised of different ecological groups based on biotic and abiotic syndromes. Melittophily was the most common (57%) pollination syndrome followed by non-specialized and ornithophily (7%). We found that 64% of species exhibited zoochory, 19% exhibited anemochory and 17% exhibited autochory. Pollination syndromes differed significantly only between types of growth form. Dispersal syndromes differed between topology, growth form and elevation. Six ecological groups were formed based on the interaction between dispersal-pollination and growth form, with predominantly zoochory in woody and anemochory in non-woody plants. Water availability may be the principal factor responsible for variation among dispersal syndromes. The proportion of ruderal species in the non-woody component explains the differences in syndromes between growth forms.

Ecological restoration encourages management for the complexity and heterogeneity of habitats, which are crucial for avian fauna structure. Two-year-old bird assemblages were evaluated based on diversity parameters of three different ecological restoration technologies applied in southern Brazil: passive restoration (PR), nucleation (NC) and high diversity plantation (HD). Richness, abundance and diversity were compared using ANOVA factorial design (three treatments x four seasons, with six samplings per season). The highest richness was observed for NC (49 ± 2.45 SD species) and the lowest richness occurred in the HD treatment (37 ± 3.14 SD species), with a similar statistical pattern for abundance and diversity (NC>PR>HD). NC responded favorably to the hypotheses of dynamic equilibrium, heterogeneity and habitat complexity, which are the probable mechanisms that influence primarily assemblage richness. Due to the presence of exclusive species for each treatment, we recommend the application of a mix of the different techniques tested to maximize the number of habitats and their interactions with birdlife.Keywords: neotropical forest, ecological restoration, avian fauna. ResumoA restauração ecológica estimula o manejo da complexidade e heterogeneidade de habitats, os quais são decisivos para a estruturação da avifauna. Foram avaliadas assembleia de aves com dois anos de idade segundo parâmetros de diversidade de três diferentes tecnologias de restauração ecológica aplicadas no sul do Brasil: restauração passiva (PR) nucleação (NC), e plantio de alta diversidade (HD). Os parâmetros de riqueza, abundância e diversidade foram comparados por meio de ANOVA em arranjo fatorial (três tratamentos x quatro estações com seis amostragens por estação). A maior riqueza observada foi constatada na NC (49 ± 2,45 espécies) e a menor riqueza ocorreu no tratamento PAD (37 ± 3,14 espécies) com um padrão estatístico semelhante para abundância e diversidade. NC respondeu favoravelmente às hipóteses do equilíbrio dinâmico, heterogeneidade e complexidade de habitats, sendo estes os prováveis mecanismos que influenciaram principalmente na riqueza da assembleia. Devido à presença de espécies exclusivas a cada um dos tratamentos, recomenda-se a aplicação conjunta das técnicas testadas para maximizar o número de habitats e suas interações com a avifauna.Palavras chave: floresta neotropical, restauração ecológica, avifauna.

“…Além de anonáceas silvestres, ocorrem também palmeiras na FLONA Araripe. A dispersão e a polinização são processos ecológicos estratégicos em comunidades florestais; seu estudo tem grande importância no entendimento das variáveis envolvidas na organização da comunidade (Yamamoto, 2001). Portanto, esses insetos têm um papel importante na polinização das plantas da vegetação do Cerrado caririense.…”

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.
