The metazoan parasite fauna of snooks, Centropomus parallelus and Centropomus undecimalis, cultured in southern Brazil and parasite?s influence on the relative condition factor (Kn), are investigated. Snooks were parasitized by two species of gill monogeneans belonging to Rhabdosynochus (Diplectanidae) genus and by one endoparasitic digenean species Acanthocollaritrema umbilicatum (Acanthocollaritrematidae). Centropomus parallelus and C. undecimalis showed similar prevalence rates of Rhabdosynochus spp., but greater mean intensity and abundance rates were found in C. parallelus. On the other hand, there was no significant difference on prevalence, mean intensity and abundance of A. umbilicatumfor both hosts. The mean abundance of Rhabdosynochusspp. decreased as the hosts´ length and weight increased. Since the most parasitized fish species, C. parallelus, had lower weight than expected (Kn<1.0), the fact suggested that gill monogeneans might alter fish welfare. Current analysis reports a new host and a new locality for A. umbilicatum. |

Advancing extensive cattle production is a major threat to biodiversity conservation
in Amazonia. The dominant vegetation cover has a drastic impact on soil microbial
communities, affecting their composition, structure, and ecological services. Herein, we
explored relationships between land-use, soil types, and forest floor compartments on
the prokaryotic metacommunity structuring in Western Amazonia. Soil samples were
taken in sites under high anthropogenic pressure and distributed along a ±800 km
gradient. Additionally, the litter and a root layer, characteristic of the forest environment,
were sampled. DNA was extracted, and metacommunity composition and structure
were assessed through 16S rRNA gene sequencing. Prokaryotic metacommunities in
the bulk soil were strongly affected by pH, base and aluminum saturation, Ca C Mg
concentration, the sum of bases, and silt percentage, due to land-use management
and natural differences among the soil types. Higher alpha, beta, and gamma diversities
were observed in sites with higher soil pH and fertility, such as pasture soils or fertile soils
of the state of Acre. When taking litter and root layer communities into account, the beta
diversity was significantly higher in the forest floor than in pasture bulk soil for all study
regions. Our results show that the forest floor's prokaryotic metacommunity performs a
spatial turnover hitherto underestimated to the regional scale of diversity. |
