| Resumo: Este estudo analisou a estrutura populacional de ovinos deslanados do núcleo de conservação do estado do Ceará, Brasil. Os parâmetros populacionais foram estimados com base nos dados genealógicos de indivíduos das raças Santa Inês (SI), Somalis (SO) e Morada Nova (MN), nascidos entre os anos de 2001 e 2014. Os parâmetros estimados foram: número de gerações completas equivalentes (GCE), intervalo entre gerações (IEG), número de fundadores (Nf), número efetivo de fundadores (fe), número efetivo de ancestrais (fa), coeficiente de endogamia (F) e índice de contribuição genética (ICG). O GCE médio foi de 1,82, 2,78 e 1,52 para SI, SO e MN, respectivamente. O IEG foi próximo entre as raças, 3,67 anos em média. O Nf para SI, SO e MN foi igual a 225, 194 e... |

| The knowledge of gas exchanges in forage plants is essential for a better understanding of the process of forage biomass production in pasture. This study evaluated the gas exchange in massai grass fertilized with increasing levels of nitrogen fertilizer (control - without nitrogen fertilizer; 400; 800 and 1200 kg ha-1 year-1) and under rotational grazing by sheep, in a completely randomized design with repeated measures in time. The rest period was approximately 1.5 new leaves per tiller, as determined in the pre-test at the beginning of the experiment, providing interval of 22; 18; 16 and 13 days for the levels 0.0 - control; 400; 800 and 1200 kg ha-1 year-1 nitrogen, respectively. The animals used to lower the sward height to the recommended residual... |

| Abstract: The Saanen goat breed has been widely explored in breeding programmes; however, there are few reports about the breed?s genetic and molecular composition. Thus, this study aimed to characterize the proteomic profile of spermatozoa from Saanen breeding goats. Five breeding animals with proven fertility were selected, the spermatozoa were collected, and the protein was extracted. Subsequently, the proteins were separated and analysed by two-dimensional electrophoresis and mass spectrometry; the proteins were then identified with the SwissProt database. A total of 31 proteins involved in reproduction were identified, including binding proteins on spermatozoa for fusion with the egg, acrosomal membrane proteins, metabolic enzymes, heat shock... |

| May-to-July and February-to-April represent peak rainy seasons in two sub-regions of Northeast Brazil (NEB): Eastern NEB and Northern NEB respectively. In this paper, we identify key oceanic indexes in the tropical South Atlantic for driving these two rainy seasons. In Eastern NEB, the May-to-July rainfall anomalies present a positive relationship with the previous boreal winter sea surface temperature anomalies (SSTA) in the southeast tropical Atlantic (20 degrees-10 degrees S; 10 degrees W-5 degrees E). This positive relationship, which spread westward along the southern branch of the South Equatorial Current, is associated with northwesterly surface wind anomalies. A warmer sea surface temperature in the southwestern Atlantic warm pool increases the... |
