This study investigated the diversity of metazoan parasites in Colossoma macropomum from the Jari River, in the eastern Amazon, northern Brazil. We collected a total of 4966 parasites from 34 fishes, including monogeneans (Anacanthorus spathulatus, Mymarothecium boegeri, Notozothecium janauachensis and Linguadactyloides brinkmanni), nematodes (Spectatus spectatus larvae, Contracaecum sp. larvae andProcamallanus (Spirocamallanus) inopinatus), digeneans (Cladorchiidae metacercariae), acanthocephalans (Neoechinorhynchus buttnerae), crustaceans (Ergasilus turucuyus, Argulus multicolor, Perulernaea gamitanae and Braga patagonica), mites and leeches. The dominance was of monogenean species, found in the gills of the hosts. The parasites exhibited high aggregate dispersion, except Contracaecum sp. and P. (S.) inopinatus that showed uniform and random dispersion, respectively. The species richness of parasites varied from 1 to 9, the Brillouin diversity index from 0 to 1.52, evenness from 0 to 0.63 and the Berger-Parker dominance index from 0.39 to 1.00. Abundance of parasites was not influenced by host length, but there was significant correlation with host body weight in some cases. The parasite community was characterized by low species richness and moderate diversity, with a predominance of ectoparasites with high prevalence and abundance, as well as the presence of endoparasites in the larval stage. |

Environmental degradation, over the years, has drastically changed landscapes in the Amazon. At the same time, discussion, knowledge, and actions on the conservation of forest remnants and restoration of degraded environments have increased worldwide. The present study, carried out in Paragominas (Brazilian Amazon), aimed: (1) to evaluate the process of landscape change over the last 36 years (1984-2020); (2) to identify degraded environments within legally established permanent preservation areas (PPAs); and (3) to map environmental liabilities in degraded rural properties which, according to environmental regulations, must be recovered. The priority areas for restoration were defined considering (a) the environmental liabilities of each rural property; (b) the remnant forest in each rural property; (c) the rural properties? boundaries; and (d) the degraded PPAs in each rural property. Deforestation followed by land use change in Paragominas? territory increased from 12% (2336 km2) in 1984?45% (8783 km2) in 2020. The municipality presented 4416 km of rivers and c.a 6157 springs under pressure (i.e. agriculture, pasture, urban areas and deforested areas). The environmental liabilities identified summed 638.85 km2, which, according to environmental regulations, must be recovered. It is important to consider that when producers protect PPAs in their properties, they also conserve soil and water resources as well as contribute to biodiversity maintenance. |
