    O trabalho foi realizado com objetivo de avaliar o valor nutritivo de resíduos de frutas derivados da extração de sucos e polpas. Foram estudados os resíduos de abacaxi, acerola, goiaba, maracujá e melão, devidamente desidratados, até que atingissem teor de umidade entre 13 e 16%. Foram utilizados 20 ovinos SRD, machos e castrados, em delineamento inteiramente casualizado com cinco tratamentos (resíduo das frutas), e quatro repetições. Foram avaliados o consumo de matéria seca (CMS) expresso em: g/animal/dia, %PV e g/UTM (PV0,75), e a digestibilidade da matéria seca(DMS), tendo sido feito a análise de variância e comparação de médias. Os maiores CMS (g/animal/dia, %PV e g/UTM) foram obtidos para os resíduos de goiaba, maracujá e melão. O resíduo de acerola apresentou CMS inferior (P>0,05) a todos os outros estudados. O resíduo de maracujá apresentou DMS superior (P<0,01) aos demais resíduos e os resíduos de acerola e goiaba apresentaram a menor DMS. Portanto, os resíduos de frutas estudados podem ser utilizados na alimentação animal por apresentarem CMS e DMS semelhantes a volumosos de boa qualidade. Voluntary intake and dry matter digestibility of fruit processer agroindustry byproducts. ABSTRACT: The study was conducted to evaluate the nutritional value of residues of the juices and pulps extraction. The residues of pineapple, acerola, guava, passion fruit and melon, were properly dehydrated, until that reached humidity between 13 and 16%. It was used 20 SRD sheeps, males and castrated in complete randomized design with five treatments (fruits residues) and four replications. It was estimaded the dry matter intake (DMI) expressed in: g/animal/day; percentage of body weigth (%BW) and g/BW0.75, and dry matter digestibility (DMD), having been made analysis of variance and average comparisons. The higher DMI (g/animal/day, %BW and g/BW0.75) was reachedto the guava, passion fruit and melon residues. Therefore acerola residue presented lesser DMI than others residues. Passion fruit residue presented higter DMD than all residues studied. The acerola and guava residues presented small DMD. The fruits residues studied can be used in animal feeding, because presented IMD and DMD similar to forages of good quality

    Tropical tree growth driven by dry-season climate variability

    Interannual variability in the global land carbon sink is strongly related to variations in tropical temperature and rainfall. This association suggests an important role for moisture-driven fluctuations in tropical vegetation productivity, but empirical evidence to quantify the responsible ecological processes is missing. Such evidence can be obtained from tree-ring data that quantify variability in a major vegetation productivity component: woody biomass growth. Here we compile a pantropical tree-ring network to show that annual woody biomass growth increases primarily with dry-season precipitation and decreases with dry-season maximum temperature. The strength of these dry-season climate responses varies among sites, as reflected in four robust and distinct climate response groups of tropical tree growth derived from clustering. Using cluster and regression analyses, we find that dry-season climate responses are amplified in regions that are drier, hotter and more climatically variable. These amplification patterns suggest that projected global warming will probably aggravate drought-induced declines in annual tropical vegetation productivity. Our study reveals a previously underappreciated role of dry-season climate variability in driving the dynamics of tropical vegetation productivity and consequently in influencing the land carbon sink
