Interações entre frugívoros voadores e plantas em um fragmento de floresta estacional semidecidual, Botucatu, SP

Plant-frugivore interactions are essential elements in ecosystem and their knowledge can becomes an important tool for the biodiversity maintenance. This study focused on analyzing the trophic structure of volant frugivore community and its implications for conservation. Bats and birds interactions events with plants were taken from three studies realized in Mata da Bica, a fragment of semideciduous seasonal forest in Botucatu- SP, and arranged in a matrix. A total of 40 interactions with 14% of connectance were found and only one dietary overlap between birds and bats was registrated. Carollia perspicillata (Phyllostomidae) bat showed the highest importance index (I=0,33) among the animals and Pereskia aculeata (Cactaceae) was the most important plant species (I=0,42). Birds and bats complemented each other in a possible dispersal process emphasizing different classes of animals’ role in an unique ecological process

Seed germination and removal of Michelia champaca L. (Magnoliaceae) in eucalypt stands: the influence of the aril

Testou-se o efeito do arilo na germinação de M. champaca em condições controladas, bem como na sua remoção, em ambiente natural. Os ensaios de germinação foram mantidos a 25 ± 2 °C, sob luz branca constante. Os experimentos de remoção foram levados a cabo em três talhões velhos (idades de 39 a 62 anos) e três novos (15 anos de idade) de eucalipto mantidos no Horto Florestal Navarro de Andrade, em Rio Claro, SP. Os resultados indicaram que o arilo inibe a germinação, sendo as sementes fotoblásticas positivas. Observou-se que a remoção de sementes foi maior em talhões velhos do que em novos, provavelmente devido à maior densidade de roedores nos talhões velhos. Nos talhões novos, verificou-se que formigas removiam mais sementes ariladas. Esses insetos são importantes agentes na remoção do arilo de sementes derrubadas por pássaros, promovendo, assim, aumento na germinação e evitando a possível predação das sementes por roedores.

Parque Estadual da Serra do Mar, Núcleo Santa Virgínia (SP): um estudo de vazão de contribuição pelo método de regionalização hidrológica

Seeking the integrated management of water resources and financial compensation especially as a management tool, according to the Law No. 9433 of 1997 and No. 9985 of 2000. This research's main objective is measuring the flow contribution of Núcleo Santa Virginia, the State Park of Serra do Mar, starting from the hydrological regionalization method, developed by the Department of Water and Power. According to the Law 9985 of 2000 Conservation Units have the right to receive in the form of an investment a portion of the amount paid by Power Plants, being passed directly to the Conservation Units, differently from the 9433 Act. By dividing the area of Núcleo Santa Virgínia, in Sub-basins, it was possible to find the minimum flow during seven consecutive days, with a return period of ten years, Q7,10, and steady water flow in 95% of the time, Q95 for the Center and from these data to calculate the monetary value of law under Articles 47 and 48 from Law 9985 of 2000

Acaricides used in conventional and organic citrus orchard: leprosis and phytoseiid mites population control

The citrus leprosis control in São Paulo state is performed exclusively by acaricides to control the vector mite, Brevipalpus phoenicis, which increases the production costs and may affect the beneficial organism's population. Therefore, the aim of this trial was to evaluate during four seasons, the effects of acaricides recommended to control the mite B. phoenicis in conventional and organic citrus over evolution of citrus leprosis and over phytoseiids' population. The experiment was installed in October of 2003 in a citrus orchard in Reginopolis city, state of São Paulo. The experimental design used randomized blocks, the dosages was expressed as mL c.p./100L of water and the treatments were the following: spirodiclofen (20 mL); cyhexatin (50 mL) (used in rotation), lime sulfur (4,000 mL) and control (without pesticide application). However, the rotation between spirodiclofen and cyhexatin began in September 2006. Prior to that time, only spirodiclofen had been used. Surveys were conducted every 15 days on the B. phoenicis, Iphiseioides zuluagai, and Euseius populations. The control level adopted by the B. phoenicis was 8.3%, and the pesticide applications were conducted using tractor-sprayers. During the 2007-08 seasons, 10 infected fallen fruits per plot were collected and the number of leprosis lesions was quantified by each fruit. By the end of the 2007-08 seasons, the productivity, harvest losses, the disease incidence and severity were evaluated. It was found that the lesions' location over the fruit is more important in determining its drop than the lesions' number. The more intense the mite infestation, the greater is the number of lesions, resulting in increased premature fruit drop. A strategy using acaricides spirodiclofen and cyhexatin in rotation promoted more efficient control of B. phoenicis compared to lime sulfur, resulting in greater productivity, lower fruit losses and severity levels. The lime sulfur applications reduced the mite population incidence below the control level; however it did not prevent the lesions' occurrence. The acaricides applicarevented adverse effects on phytoseiid population because there was a reduction of their density.

Aspectos técnicos e econômicos da poda e do controle químico de Brevipalpus phoenicis no manejo da leprose dos citros

The objective of this study was to evaluate different citrus leprosis management tactics during seven seasons, based in pruning and acaricide applications, considering technical and economic aspects of each tactic. The trial was conducted from October 2003 to August 2010 in an orange plantation of Pera cv. located in the municipality of Reginópolis-SP, Brazil. The plants of citrus used were12 years old and grafted onto Cleopatra tangerine. The experimental design used was randomized blocks, in a factorial scheme, made up of factors type of pruning (A), with six levels: (1) drastic pruning, (2) intermediate pruning without leprosis lesions, (3) intermediate pruning with leprosis lesions (4) light pruning, (5) without pruning and (6) replant; acaricide applications factor (B), with three levels: (1) without acaricides applications, (2) with lime sulfur applications and (3) spirodiclofen or cyhexatin applied in rotation; pruning factor to remove leprosis symptomatic branches (C), with two levels: (1) with pruning for removal, (2) without removal pruning. The combination of factors, with respective levels (6 x 3 x 2), resulted in 36 treatments that were repeated four times, with each parcel being made up of three plants in a row. After seven years, it was observed that the types of the pruning and remove of leprosis symptomatic branches used as single management tactic, is not sufficient to leprosis control. Therefore, the results demonstrated that for leprosis management, it is essential the association between tactics, especially the control mite vector. For ensuring the citrus production economically, the use of acaricides highly efficient is essential in B. phoenicis control. The recommendation of the type of pruning should be in function of the leprosis incidence and severity in the orchard. In orchards with low leprosis incidence and severity the light pruning is more appropriate, because it is efficient and ensures greater financial balance. However, in orchards with high leprosis incidence and severity it is indicated the severe pruning for reducing or eliminating inoculum source. Between the severe prunings, the intermediate pruning with leprosis lesions is the most relevant, because the financial return will be faster. Replant is indicated only for young orchards, because does not imply in changes onto cultural practices.
