| The objective of this study was to evaluate the feeding management of pacu juveniles (P. mesopotamicus) under different feeding rates and its relation with productive performance, body composition and hematological characteristics. A total of 300 fish with initial weight of 84.75±4.52 g were distributed in a completely randomized design composed of four treatments (100, 90, 80 and 70% of feed supply) and five repetitions. The amount of feed was stipulated according to the quantity supplied in the treatment until apparent satiation (100%) of the day before. The decrease in the feeding rate to 70% over satiation apparently improves the apparent feed conversion without harming performance, body composition or biochemical and hematological characteristics of... |

| Swine is an important exploration of Paraná’s cattle raising, promoting the generation of employment and income in rural areas, however, it generates large amounts of solid and liquid residues. Based on these considerations, the objective of this work was to analyze the development of native tree species submitted to fertilization with swine wastewater. Four native tree species were selected: Anadenanthera colubrina (Vell.) Brenan (Fabaceae), Astronium graveolens Jacq. (Anacardiaceae), Cordia trichotoma (Vell.) Arráb. ex Steud (Boraginaceae) and Heliocarpus popayanensis Kunth (Malvaceae). The applied doses of wastewater had been of 0, 25 and 50 m3 ha-1. They were applied every two months, adding up a total of 6 applications and the measured morphometric... |

| Despite the possible influence of tannins on the nutritional value of the forages from Caatinga vegetation, there are few studies that evaluated their tannin concentration. This study was conducted to characterize condensed tannins present in the legumes species Mimosa hostilis (Jurema Preta), Mimosa caesalpinifolia (Sabiá) and Bauhinia cheilantha (Mororó), at three stages of their phenological cycle. The concentration of soluble tannin (ST), bound tannin (BT) and total tannin (TT) were determined using the butanol-HCL method; astringency was by the radial diffusion method, and the monomeric composition of purified tannins by a high-performance liquid chromatograph with delphinidin, cyanidin and pelargonidin as standards. Concentration and astringency of... |

| ABSTRACT Ferruginous Rocky Outcrops have high levels of species richness and endemism, but have been threatened by several anthropic actions, especially mining. Eragrostis polytricha, a common grass species in the vegetation of these outcrops, has shown promising features for use in the recovery of mining areas. However, in order to fully understand the species’ potential for such use, its requirements for germination, seed dormancy break and seedling development must be determined. Thus, we aimed to: (1) assess the temperature conditions needed for seeds of E. polytricha to germinate; (2) evaluate the effects of KNO₃ in breaking seed dormancy; and (3) analyze the germination efficiency of seeds that are still in spikelets. The experiment included seven... |

| The aim of this study was to evaluate the efficiency of vitrification and droplet vitrification for the cryopreservation of Hancornia speciosa shoot tips. The shoot tips were subjected to four different periods of exposure (15, 30, 45 and 60 min.) to plant vitrification solution 2 (PVS2) before plunging into liquid nitrogen. We evaluated the regrowth of H. speciosa shoot tips that were cryopreserved by the classical vitrification technique and by the droplet vitrification technique. Shoot tips were submitted to different periods of pre-culture (absence, 24 or 48h) in a medium containing 0.3 M sucrose prior to cryopreservation. With a PVS2 exposure period of 60 min., significant differences were observed between the two techniques used in this study with... |

| O presente estudo avaliou o óleo de cravo como anestésico para juvenis de dourado em cinco diferentes concentrações (20, 30, 40, 50 e 60 mg L-¹), utilizando como critério para determinação da concentração ideal os tempos de indução e de recuperação ao efeito do anestésico. Em relação aos tempos de indução, verificou-se diferença significativa (p < 0,05) entre as concentrações de 20, 30, 40 e 60 mg L-¹ de óleo de cravo. No entanto, a concentração de 50 mg L-¹ não diferiu estatisticamente dos níveis de 40 e 60 mg L-¹. Quanto à recuperação, o menor tempo foi verificado para a concentração de 20 mg L-¹. O óleo de cravo é eficiente e seguro como anestésico para juvenis de dourado, quando utilizado entre 40 a 60 mg... |

| The Brazilian Cerrado is the richest savanna in the world. It is also one of the biomes more threatened in the country and a hotspot for conservation priorities. The main causes of deforestation in Cerrado are agricultural practices, livestock and charcoal production. Although charcoal has a minor impact, its consumption represents the deforestation of 16.000 Km² of the Cerrado. To contribute for the biomes's conservation it is very important to improve forestry supervision. Thus, in this work we present the macroscopic characterization of charcoal from 25 Cerrado's species. We simulate the real conditions of forest controllers by using the magnifications of 10x, 25x and 65x. Likewise, the charcoals micrographs are all of transverse sections due to the... |

| L. Reyes-Garcia, Y. Cuevas, C. Ballesteros, T. Curkovic, C. Löfstedt, and J. Bergmann. 2014. A 4-component sex pheromone of the Chilean fruit leaf roller Proeulia auraria (Lepidoptera: Tortricidae). Cien. Inv. Agr. 41(2):187-196. The Chilean fruit leaf roller Proeulia auraria is a pest of economically important fruit species. Two compounds attractive to males have been identified as (E)-11-tetradecenyl acetate (E11-14:OAc) and (E)-11-tetradecenol (E11-14:OH) and are currently being used in Chile to monitor this species. Preliminary experiments carried out by our group suggested that the 2-compound mixture might not be optimal for the attraction of males, which prompted us to reinvestigate the sex pheromone of P. auraria in the present study. The pheromone... |
