This study describes the parasitic fauna of Mylossoma duriventre caught at Lake Coari, a tributary of the middle Solimões River, in the state of Amazonas (central Amazon, Brazil) and the relative condition factor (Kn). Out of 70 necropsied specimens, 90% had the gills parasitized by the helminth Anacanthorus paraspathulatus Kritsky, Boeger & Van Every, 1992 (Dactylogyridae: Anacanthorinae) and the intestine by Eustrongylides Jägerskiöld 1909 (Nematoda: Dioctophymatidae) larvae. A total of 19,763 specimens of A. paraspathulatus were collected, but the infection by Eustrongylides sp. larvae seemed to be accidental, after all, only three hosts were trophically infected. However, there was no significant difference (p<0.05) in the Kn of parasitized and non-parasitized fish, indicating that the intensity these parasites not affected the health of host. This is the first report on parasitic infection rates for M. duriventre, as well on infections by Eustrongylides sp. for this host. |

The association between changes in land use combined with climate variations partially explains the degradation in the water resources of the Brazilian semiarid. The existence of local and regional tendencies in meteorological variables, which are important for agricultural and electric energy production sectors, and centers for prediction of meteorological extremes, was investigated, using parametric and non-parametric statistical tests. The application of the Mann-Kendall sequential test allowed detection of years when tendencies of increase or decrease in atmospheric humidity started by using meteorological data from the period 1975 to 2015. The results indicate that, despite the observed similarities in the climate regime, the Bebedouro PE) and Mandacaru (BA) regions show distinct variability patterns, which may be attributed to effects caused by interventions in soil cover and use. Changes in the atmospheric pattern that favored the occurrence of extreme precipitation events were investigated by means of factorial analysis. The increase in atmospheric moisture due to agricultural expansion in Caatinga areas is one of the main factors involved in the increase of cloudiness |
