RESUMEN.
Los acridios (Orthoptera: Caelifera: Acridoidea) son insectos nativos que habitan pastizales en Uruguay. En ciertas ocasiones incrementan la abundancia exponencialmente, como en los años 1950´ y en 2008/09, causando importantes pérdidas económicas. Este trabajo tuvo como objetivo describir la variación interanual de la abundancia y diversidad de las comunidades que habitan pastizales de la región centro-sur. El seguimiento de las poblaciones se realizó durante cinco temporadas, en sitios de Florida y Durazno. Se estimaron: riqueza acumulada y específica por sitio (S), índices de diversidad de ShannonWeiner (H´), equitatividad de Pielou (J´), similitud cualitativa de Sorensen (Is), constancia de presencia (C), y abundancia total (A), específica absoluta y relativa. A través de las variaciones temporales de dichos descriptores comunitarios se identificaron y caracterizaron períodos de explosión poblacional, transición y equilibrio. En 2009/10 (explosión poblacional) S, A, e Is fueron máximos, J? y H? bajos y Borellia bruneri (Rehn, 1906) fue la más abundante. El período 2010/11-2011/12 (transición), se caracterizó porque J´ e Is fueron intermedias, A y S bajas, y continuó el predominio de B. bruneri. Durante 2012/13 y 2013/14 (equilibrio), se registraron los más altos J´ y H´, y la abundancia relativa de B. bruneri disminuyó significativamente. En este período Scotussa lemniscata (Stål, 1861) fue predominante. Los resultados obtenidos indican que en pastizales de la región centrosur
del Uruguay, el predominio de B. bruneri, la disminución en J´ y el aumento de Is serían indicadores de un período de transición hacia una explosión poblacional.

SUMMARY
Acridians (Orthoptera: Caelifera: Acrididae) are native insects that inhabit Uruguayan grasslands. Occasionally, abundance increases exponentially, as in the 1950' and in 2008/09, causing significant economic losses. This work aimed to describe the variation in the abundance and diversity of the communities that inhabit the grasslands of south-central region. Acridian populations were monitored during five seasons in Florida and Durazno sites. Cumulative and site-specific (S) richness,
Shannon-Weiner (H ?) diversity index, Pielou evenness (J?), qualitative similarity of Sorensen (Is), constance of presence (C), total abundance (A), and absolute and relative specific abundance were estimated. Based on these community descriptors and their temporal variations, we identified and characterized outbreak, transition and non-outbreak periods. In 2009/10 (outbreak) S, A, and Is , were highest, J ? and H? were low, and Borellia bruneri (Rehn, 1906) was the most abundant species.
The 2010/11 -2011/12 period (transition), was characterized by intermediate J? and Is , low A and S, and B. bruneri remained predominant. During 2012/13 and 2013/14 (equilibrium), higher values of J ?and H?, and low values of A, S and Is were recorded, and the relative abundance of B. bruneri decreased significantly. In this period Scotussa lemniscata (Stål, 1861) was the predominant species. These results indicate that in the grasslands of south-central region of Uruguay, the prevalence
of B. bruneri, the decrease in J? and increase in Is , would be indicators of a transition period to an outbreak. MenosRESUMEN.

Abstract-
We investigated the physiological relationship between diet during pregnancy and colostrum production in ewes to test the hypothesis that for ewes that are in low body condition, with low fat reserves, the food supply will be the main source of energy for colostrum synthesis. To this end, we measured the amount of colostrum accumulated by ewes under two levels of nutrition. We also measured the circulating concentrations of metabolites and hormones associated with lactogenesis (beta-hydroxybutyrate, glucose, progesterone, prolactin, cortisol, growth hormone, leptin, insulin and insulin-like growth factor-I) Ewes were either under-fed at 70 (n = 15) or well-fed at 110% (n = 10) of their daily metabolisable energy requirement during the last two months of pregnancy. Colostrum accumulation up to parturition was 168 +/-48 g for under-fed ewes and 451 +/-103 g for well-fed ewes. After birth, under-fed ewes produced less colostrum than well-fed ewes but the difference was no longer significant. The level of nutrition also influenced the plasma concentrations of hormones and metabolites related to lactogenesis. Progesterone concentrations decreased before lambing in all animals but in under-fed ewes the fall appeared to be too small to initiate the onset of colostrum production. Beta-hydroxybutyrate concentrations were higher in under-fed than in well-fed ewes, suggesting that the under-fed ewes were mobilising more adipose tissue but they still did not meet their ME requirements for colostrum production. We concluded that, in underfed ewes, there are insufficient nutrients for adequate lactation and the hormone regime is inappropriate for good udder development and colostrum synthesis. MenosAbstract-
