Fatores genéticos e de Meio na idade ao primeiro parto de caprinos leiteiros

Data on age at first kidding (IPP) were collected on seven farms in the Brazilian Southeastern region which explored breds. Least squares (LS) were used to evaluate the effects of environmental factors and to estimate variance components, and the derivative-free restricted maximum likelihood (DFREML) method was used to estimate the variance components of IPP and to genetically evaluate the goats used in the southest region of Brazil. The LS mean and standard error of IPP were 607.18 +/- 17.09 days. The interaction of year x kidding season had a significantly influenced IPP, indicating that management conditions varied among the seasons within each specific year, with a direct influence on body weight which is the main criterion adopted by farmers to decide when the animal is ready to breed. The effect of farm-breed combination influenced the IPP. The compararison among levels of farm-breed were done by cluster analysis. The results indicated that the individual goat management within each farm had a greater influence than breed, since goats of different breeds showed high and similar values on those farms having a high mean IPP. Heritability estimates obtained by LS using intraclass correlations among paternal half-sibs and those obtained by REML were 0.220 and 0.369, respectively.

Doses de inoculante e nitrogênio na semeadura da soja em área de primeiro cultivo

The inoculation of soybean crop with Bradyrhizobium bacteria is a widespread practice, due to excellent results achieved in productivity, however, some doubt still arise in relation the need of application of mineral nitrogen at sowing. In that mean, this work aimed to evaluate the response of the doses at inoculant and mineral nitrogen in the sowing of crop soybean in area of first cultivation. The experiments were carried in the experimental field of the University of the Estate of Mato Grosso, Campus of Alta Floresta - MT, Brazil, in the growing seasons of 2006/2007 and 2007/2008. The experimental design was randomized blocks, in a factorial escheme 2 x 4, with four replications. The factors consisted in the inoculation of seeds with Bradyrhizobium japonicum *(3 e 6 mL kg(-1) of seeds), and nitrogen fertilizer at sowing *(0, 10, 20 e 40 kg ha(-1)). The following variables were evaluated: plant height, insertion height of first pod, number of pod per plant, number of grain per pod, mass of 100 grain and grain productivity. In the two growing seasons there was no significant difference for doses of inoculants applied in first year of cultivation with soybean. To nitrogen application at sowing of soybean crop there was quadratic effect to plant height and of insertion height of first pod and growing linear to number of pod per plant in the second year of cultivation, however, without significant increase the productivity.

Quirópteros da Estação Ecológica da Serra das Araras, Mato Grosso, Brasil, com o primeiro registro de Artibeus gnomus e A. anderseni para o cerrado

We present the results of the first bat inventory at the 'Serra das Araras' Ecological Station, MT, in the northwestern portion of the Cerrado domain. We captured bats using the traditional ground-level mist netting and, occasionally, high nets placed 3 m above the ground, and hand nets for hoosting bats. We recorded 23 species distributed in six families (Emballonuridae, Noctilionidae, Mormoopidae, Phyllostomidae, Molossidae, and Vespertilionidae), including Artibeus gnomus and A. anderseni, which had never been recorded in the Cerrado domain. © 2004 Instituto de Ciências Biológicas - UFMG.

Primeiro registro documentado de Alectrurus tricolor para o Pantanal, Brasil

The Cock-tailed Tyrant (Alectrurus tricolor, Vielliot 1816) is reported here for the first time in the Brazilian Pantanal. The species was seen twice (August and September 2005) in the northern portion of Fazenda Rio Negro, in the region of Nhecolândia. Sexual displays were observed, suggesting that reproduction is occuring in this area.

Utilização do primeiro ciclo ovulatório da estação reprodutiva para produção de embriões em éguas sob condições tropicais

The efficacy of the first ovulation of the breeding season was determined through the response of first pre-ovulatory follicle of the breeding season to hCG, embryo recovery rate, viability of recovered embryos, serum concentrations of progesterone, and response of first CL to PGF 2α. Thirteenth mares that were in vernal transition were accompanied until the first pre-ovulatory follicle was detected. At this moment, the ovulation was induced with 2,500 IU hCG (IV) and the mares were inseminated every other day until ovulation. Seven days after the ovulation, embryo recovery was performed and the progesterone concentration was determined. After detection of the first pre-ovulatory follicle of breeding season with ≥ 25mm, it took 14.92 ± 10.80 days for the follicle to reach the preovulatory size and 18.00 ± 11.08 days to ovulation. After administration of hCG, 11/13 mares ovulated in 48 hours. These follicles growth 2.19 ± 0.86 mm/day on average. Nine of 13 mares (69.2%) produced embryos and all were considered viable after morfological evaluation and fluorescence exams. The CL appeared competent producing 7.39 ± 2.11 ng/ml P 4 on average, and responding to PGF 2α. According to these results the first ovulatory cycle of the year can be utilized to produce viable embryos.

Primeiro registro de Harpia harpyja para o bioma Pantanal, com dados sobre atividade reprodutiva

The first reliable encounter of the Harpy Eagle Harpia harpyja in the Pantanal floodplains is reported, with information on its breeding activity in the region, as well as some prey. A nest was found in August 2009, located in Barão de Melgaço County, northern portion of the Pantanal, with a 60-90-day-old eaglet. After a windy storm on August 30, the nest fell, causing the death of the nestling. In March 2010 another nest was located about 2.6 km distant from the first. We emphasize the importance of this record, and the need for a monitoring program to evaluate the true status of the Harpy Eagle in the northern portion of the Pantanal and nearby areas.

Primeiro relato de atividade patogênica de Hirsutella thompsonii (Fischer) sobre o ácaro-da-erinose-da-lichia Aceria litchii (Keifer)

The litchi erineum mite, Aceria litchii (Keifer) is found in all producing regions attacking leaves and flowers of litchi plants. The mite attack young leaves and causes the erinea on leaf surface, which later become brown galls with velvety appearance. Severe attacks can cause leaf drop and destruction of branches end directly production affecting. In 2009 year it was registered a heavy infestation of the pest on litchi plants (Litchi chinensis Sonn.) in the municipality of Casa Branca, São Paulo, Brazil (2127'O; 4702'S; 679 m altitude). In June, many galls caused by mite infestation showed a mycelium of white coloration and many eriophyid dead. The fungus was identified as Hirsutella thompsonii (Fischer). The results suggest that galls may facilitate the fungus development and its permanence on the plants. Thus, the possibility of mite biological control with H. thompsonii should be investigated.

Primeiro registro de Molossus coibensis (Chiroptera: Molossidae) na Amazônia Brasileira

This study reports on the occurrence of Molossus coibensis J. A. Allen, 1904, in the Brazilian Amazon and the second record of this species from Brazil. It also presents a comparative analysis with other two small-bodied Molossus species that occur in Brazil: M. molossus (Pallas, 1766) and M. aztecus Saussure, 1860. The report is based on 8 females captured in urban areas of the city of Bragança, in the northern Brazilian state of Pará. Morphometric data and the qualitative comparison of morphological features permitted the identification of the specimens as M. coibensis, hitherto known only in Tapirapoan, in the southwestern state of Mato Grosso, west-central Brazil. © SAREM, 2013.
