Establishing new grid-size-dependent attributes to rank areas of endemism for conservation priorities. [PDF]
CladisticsAbstract Delineating Areas of Endemism (AEs) is crucial for identifying priority areas for biodiversity conservation in a spatial planning framework. Endemicity Analysis in the NDM/VNDM software is one of the primary methodologies for its delineation.

Ecology of Freshwater Fish, Volume 32, Issue 4, Page 926-937, October 2023., 2023 Abstract Non‐native fish species may generate major ecological impacts on native assemblages. This study aims to assess the potential impact of the introduced Arapaima gigas on native fish assemblages in two oxbow lakes of the Bolivian Amazon. Stable isotope data were used to determine trophic position (TP) and isotopic niche overlap, to evaluate ...

Fisheries in a border area of the Moxos Lowlands (Bolivia) after invasion of Arapaima gigas
Aquaculture, Fish and Fisheries, Volume 3, Issue 2, Page 196-210, April 2023., 2023 We characterized fisheries in the area of the port city of Riberalta (upper Madeira River basin) and evaluated the contribution of an invasive species (Arapaima gigas) to the landings. A. gigas represented 57.6% of the overall economic value of fish in the region.

Balancing protein and energy in Nile tilapia feeds: A meta‐analysis
Reviews in Aquaculture, Volume 14, Issue 4, Page 1757-1778, September 2022., 2022 Abstract Farmed fish are increasingly grown in intensive and semi‐intensive systems where most nutrients are provided by formulated feeds. These are formulated to minimise costs and optimise growth, notably the rate of muscle protein synthesis (i.e., fillet). Protein synthesis depends on the availability of amino acids (i.e., protein) and energy. Thus,

Integrated Environmental Assessment and Management, Volume 17, Issue 1, Page 13-26, January 2021., 2021 ABSTRACT Despite the risk of significant adverse toxicological effects of Hg to humans and wildlife, Hg use in anthropogenic activities, and artisanal small‐scale gold mining (ASGM) in particular, is widespread throughout Latin America. However, there are few research and monitoring studies of Hg toxicity in fish and fish‐eating wildlife in Latin ...

Metacercariae of Austrodiplostomum compactum (Trematoda, Diplostomidae) in non-native fish species in Brazil: a possible explanation for the high rate of parasitic infection [PDF]
Anais da Academia Brasileira de Ciências, 2020 Metacercariae of Diplostomidae are widely distributed in America and may cause diplostomiasis, an ocular disease in fishes. The aim of this study is to report the occurrence of metacercariae of Austrodiplostomum compactum in Plagioscion squamosissimus ...

Restoration Effects of the Riparian Forest on the Intertidal Fish Fauna in an Urban Area of the Amazon River. [PDF]
ScientificWorldJournal, 2016 Urbanization causes environmental impacts that threaten the health of aquatic communities and alter their recovery patterns. In this study, we evaluated the diversity of intertidal fish in six areas affected by urbanization (areas with native vegetation, deforested areas, and areas in process of restoration of vegetation) along an urban waterfront in ...

Re-evaluation of certain aspects of the EFSA Scientific Opinion of April 2010 on risk assessment of parasites in fishery products, based on new scientific data. Part 2. [PDF]
EFSA JAbstract The objective of this opinion was to determine if any wild caught fish species, originating from specific fishing grounds and consumed in the EU/EFTA could be considered free of zoonotic parasites. In this Opinion the term ‘fishery products’ only refers to fresh finfish.
