O objetivo deste trabalho foi avaliar o efeito dietário da selenometionina sobre a histopatologia do fígado de tilápia‑do‑nilo (Oreochromis niloticus). A selenometionina foi adicionada à dieta‑base (sem suplementação) nas doses de 0,25, 0,50, 1,0 e 1,50 mg kg‑1, que consistiram em cinco tratamentos, com quatro repetições. Após 90 dias de experimento, foi observada degeneração lipídica no fígado dos animais que receberam a dieta sem suplementação, o que indica deficiência de selênio. No entanto, os animais que receberam acima de 1,0 mg kg‑1 apresentaram hipertrofia, acúmulo de glicogênio, desarranjo cordonal, focos de necrose e degeneração lipídica no fígado. A incorporação de selênio é essencial para a nutrição de tilápias‑do‑nilo; porém, níveis acima de 1,0 mg kg‑1 de selenometionina prejudicam o metabolismo hepático. |

In order to incorporate biological parameters into soil quality monitoring, a French program «
RMQS-biodiv » was performed at the regional scale (Brittany, France). This program assessed
a range of biological parameters, and was connected to another soil monitoring network
developed at the national scale (Soil Quality Measurement Network- RMQS) which monitor
agro-pedological parameters. The connexion of both programs allowed the merge of both biotic
and abiotic data in a larger dataset, the analysis and the monitoring of soil biodiversity (species
and functions) in relation to land use (mainly agricultural practices) and/or pedoclimatic
parameters.
The RMQS-Biodiv Program also focussed on the optimization of soil biota sampling procedures
with the objective of their necessary standardization at national or European levels. It finally
assessed emerging criteria with respect to their relevance vs their cost effectiveness before
promoting them towards practical field actors.
Thus, this programme required an important research network to measure a large range of
biological parameters: macrofauna (earthworms, total macrofauna), mesofauna (acarina and
collembola), microorganisms (nematodes, microbial biomass, bacterial and fungal diversity),
and also functional biological parameters (soil respiration, humus index).The pilot area covered
more than 27 000 km² and the sampling scheme followed a systematic approach based on a
16 X 16 km squared grid. 115 sites were sampled in 2006 and 2007. The sampling methods
adapted to the present study context were designed to meet, as far as possible, the ISO
standards.
This paper will expose the logistics required to perform this type of program. Moreover, the
protocols and procedures will be discussed with respect to the ISO standards and to the
propositions and recommendations made by the ENVASSO project (Environmental Assessment
of Soil for Monitoring). MenosIn order to incorporate biological parameters into soil quality monitoring, a French program «
