| Floristic composition and dispersal syndromes were determined along one year in an open ombrophilous forest fragment in the Municipal Park of Maceió, Alagoas State, Brazil. A total of 178 species belonging to 61 families were examined. Fabaceae was the most species-rich family, with 24 species. Among sampled species, 123 had their syndromes of diaspore dispersal determined, and most of them (69%) were zoochoric. Anemochoric and autochoric plants represent 11 and 20% from the total, respectively. The data about reproductive phases indicate coincident peaks of flowering and fruiting in August, at the end of the rainy season. The results are in accordance to those expected for ombrophilous forest with poorly defined seasonality. |

| ABSTRACT The phenological growth stages of various species of monocotyledonous and dicotyledonous plants can be uniformly coded using the Biologische Bundesanstalt, Bundessortenamt, und Chemische Industrie (BBCH) scale. The aim of the present study was to determine the duration of different phenological stages and the temperature requirements of the sugar-apple, Annona squamosa, during two crop cycles in the semiarid region of Brazil. Phenological stages were divided into eight of ten possible principal stages: (0) bud development, (1) leaf development, (3) shoot/branch development, (5) inflorescence emergence, (6) flowering, (7) fruit development, (8) fruit maturity and (9) senescence and the beginning of dormancy. The phenological cycle of the... |

| Abstract The light-attracted silk moths (Lepidoptera: Saturniidae) of the Boraceia Biological Station in the municipality of Salesópolis, state of São Paulo, southeastern Brazil have been sampled over more than seven decades (1942-2013). A total of 6,288 individuals (including a gynandromorph) belonging to five subfamilies, 46 genera and 133 species were identified. Hemileucinae was the most abundant and speciesrich subfamily, followed by Ceratocampinae, Arsenurinae, Saturniinae, and Oxyteninae. Hylesia Hübner, Automeris Hübner, and Dirphiopsis Bouvier (Hemileucinae) were the dominant genera in abundance and species richness. Only Automeris illustris (Walker), Gamelia remissoides Lemaire, and Hidripa paranensis (Bouvier) (Hemileucinae) were recorded in all... |

| The cerrado's flora comprises aluminum-(Al) accumulating and non-accumulating plants, which coexist on acidic and Al-rich soils with low fertility. Despite their existence, the ecological importance or biological strategies of these functional groups have been little explored. We evaluated the leaf flushing patterns of both groups throughout a year; leaf concentrations of N, P, K, Ca, Mg, S, Al, total flavonoids and polyphenols; as well as the specific leaf area (SLA) on young and mature leaves within and between the groups. In Al-accumulating plants, leaf flushed throughout the year, mainly in May and September; for non-accumulating plants, leaf flushing peaked at the dry-wet seasons transition. However, these behaviors could not be associated with... |

| We carried out a qualitative and quantitative inventory of the hawkmoth fauna (Sphingidae) of an area of semi-deciduous seasonal rainforest in the state of Pernambuco (Tapacurá Ecological Station), northeastern Brazil. Hawkmoths were sampled monthly from October 2004 to February 2007 (27 months). We recorded 31 species from 16 genera, three tribes, and three families. Macroglossinae was the most abundant subfamily and represented ca. 71% of all species. Out of the 277 individuals collected, 88.4% were males. Five new records were made for northeastern Brazil: Enyo gorgon (Cramer, 1777), Perigonia stulta (Herrich-Schäffer, [1854]), Eupyrrhoglossum sagra (Poey, 1832), Nyceryx coffaeae (Walker, 1856) and Xylophanes chiron (Drury, 1773). Eight further species... |

| We evaluated the effects of fire on the vegetative phenological behavior (crown foliage cover, sprouting, mature and young leaves) of woody species at two sites in the Brazilian savanna, one of which had been accidentally burned. We used generalized additive mixed models to test the hypothesis that: 1) fire damages total foliage cover, thus leading to changes in vegetative phenological patterns. As this hypothesis was corroborated, we also tested whether 2) the damage caused by fire to the total crown foliage cover and mature leaves is greater in evergreen than in deciduous species, and 3) the negative effects of fire on vegetative phenology persist after the first fire-free year. The first two hypotheses were corroborated, but the third was not. Fire... |

| This study evaluated the seasonal influence on the yield and chemical composition of the essential oil (EO) of Nectandra megapotamica. Fresh young (YL) and old leaves (OL) obtained from three trees in each season (Nov/2010 to Sep/2011) collected in Santa Maria-RS were hydrodistilled in triplicate. The chemical composition was determined by the gas chromatography coupled to mass spectrometry (GC-MS) and the yield on dry basis was evaluated by two-way ANOVA (seasons, development stage). Spring (Sp) and summer (Su) showed higher average incomes (0.45 and 0.33%), which occurred when flowering, fruiting, and growth of YL and senescence of OL took place, while autumn (Au) presented the lowest yield (0.25%) during the rustification of OL. The highest yield was... |

| Studies were carried out on the phenological patterns and dispersion of a plant community developed naturally after limestone mining operations, in accumulated materials of wastes (spoil banks). The objectives were to focus the seasonality of plant reproductive in a degraded environment; to analyze the community according to dispersal syndrome and to know about plant resources for the animals Monthly observations of flowering and fruiting patterns of the community were done, comparing the herbaceous, shrubs and woody species. Proportion of anemochorous and autochorous was higher in the herbaceous and shrubby strata. The zoochorous ones, on the contrary, were more frequent in the woody stratum. This study showed that natural introduction of the animals at... |

| The influence of environmental factors on sporulation of Fuligo septica (L.) Wigg. and the abundance of this species on sugar cane bagasse (Saccharum officinarum L.), stored outdoors was studied.In Northeastern Brazil, between January/1997 and January/1998, a total of 29 specimens were collected through monthly collections of aethalia. The relationships between the abundance of aethalia and rainfall, temperature, relative humidity of the air and insolation were studied. Results indicated that on the substrate analyzed, F. septica was an abundant species. Sporulation occurred in all seasons of the year, with a well-defined peak at the end of winter and beginning of spring (August/September),which was strongly influenced by rainfall. |

| A natural vegetation area, with 1269 ha, composed mainly by cerrado, located at Santa Rita do Passa Quatro Municipality, São Paulo State, southeastern Brazil (21°36-39'S, 47°36-38'W), was studied. From September 1995 to February 1997, a floristic survey was carried out, when all vascular plant species at reproductive stage were collected. The flowering and fruiting patterns of the community were studied, comparing the herbaceous and the woody species. In the herbaceous component, 239 species were found and, in the woody one, 108 species. The woody species flowered mainly at the beginning of the rainy season, while the herbaceous ones produced flowers generally at the end of that season. The proportion of anemo and autochorous species was greater in the... |

| The Wang and Engel (WE) model simulates crop development considering the non-linear response of plant development to temperature. Daily air temperature is the input for the temperature response function [f(T)] in the WE model, and because there are several approaches for computing daily temperatures, there are several ways to calculate the f(T). The objective of this study was to compare two versions of the WE model for simulating leaf number and developmental stages in maize, considering two approaches for imputing daily air temperature (daily mean air temperature and daily minimum/maximum air temperature). A two-year field experiment with the maize variety BRS Missões sown in several sowing dates was conducted in Santa Maria, Rio Grande do Sul State,... |

| Developmental models can help growers to decide management practices, and to predict flowering and harvest time. Currently, a double exponential function is proposed as a generalized temperature response function for chrysanthemum. This function is not the most appropriate because its parameters lack biological meaning. The objective of this study was to develop a nonlinear temperature response function of chrysanthemum development that has parameters with biological meaning. The proposed function is a beta function with three parameters, the cardinal temperatures (minimum, optimum, and maximum temperatures for development), which were defined as 0, 22, and 35ºC. Published data of temperature response of development of three cultivars, which are... |

| ABSTRACT: Plum growing is widespread in temperate zones. In Brazil, the exploitation of this fruit tree is extended from the colder regions of the state of Rio Grande do Sul to the south of the state of Minas Gerais. However, cultivars exploited at subtropical regions are scarce due to competition. The present study aimed to select productive cultivars of plums adapted to Brazilian subtropical conditions. In this respect, the plum cultivars ‘Fla 87-7’, ‘Gema de Ouro’, ‘Grancoure’, ‘Harry Pickstone’, ‘Januária’, ‘Santa Rosa’ and ‘Satsuma’ were grafted on the ‘Okinawa’ rootstock ‘and evaluated by two cycles in the municipality of Lavras, MG, Brazil. The phenological development, physical and chemical properties of fruits, average number of fruits per plant,... |
