Macroinvertebrate-based multimetric predictive models for evaluating the human impact on biotic condition of Bolivian streams
(Elsevier Science, 2011-05)
We developed and validated a single multimetric index based on predictive models that could evaluate anthropogenic disturbances in streams of three disparate ecoregions of Bolivia. To do so, we examined 45 candidate metrics ...
Relação entre urbanização e integridade biótica de florestas nativas.
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Sustentabilidade na Gestão Ambiental - PPGSGA-SoCâmpus Sorocaba, 2019-12-16)
Facing the unbridled anthropic actions, the fragmentation and disturbance of urban forest fragments have been causing, on a global scale, the decline of species populations, genetic losses, extinction processes, reduction ...
Validation of an index of biological integrity based on aquatic macroinvertebrates assemblages in two subtropical basins of central MexicoValidation of an index of biological integrity based on aquatic macroinvertebrates assemblages in two sub-tropical basins of central Mexico

Index of biotic integrity based on fish assemblages for pampean streams and its implementation along the Del Azul stream (Buenos Aires province, Argentina)Índice de integridade biótica baseado em assembleias de peixes em riachos pampeanos e sua implementação ao longo do riacho Del Azul (província de Buenos Aires, Argentina)
(Associação Brasileira de Limnologia, 2021-01)
Aim: Freshwater communities respond to abiotic and biotic changes in the environment, and are widely used as indicators of environmental integrity. Fish have been one of the most used biological groups for this purpose. ...
Environmental assessment in tropical streams by using abundance-biomass curves and W index in fish assemblages
(Fundação Zoobotânica do Rio Grande do Sul, 2018-09-17)
We investigated the fish fauna response to different environmental conditions of urban (three) and rural (seven) streams through biomass/abundance curves and W index of environmental stress. Negative values of W indicate ...
A multimetric index based on fish fauna for the evaluation of the biotic integrity of streams at a mesohabitat scale
(Associação Brasileira de Limnologia, 2012-12-01)
OBJETIVO: Neste estudo avaliamos se o Índice de Integridade Biótica (IBI) elaborado com base na ictiofauna é capaz de discriminar locais referência dos degradados em uma escala de meso-hábitat. MÉTODOS: A ictiofauna de 96 ...

Ecosystem services of runoff marshes in urban lowland basins: Proposals for their management and conservationLes services écosystémiques des marais collatéraux dans les bassins urbains de plaine: propositions pour leur gestion et leur conservation
(EDP Sciences, 2017-05)
The city of La Plata, Argentina, is situated in a low alluvial zone, with streams having insufficient drainage into the Río de la Plata estuary. In April 2013, a prodigious storm front caused unprecedented flooding in the ...
The protected areas system in Brazil as a baseline condition for wetlands management and fish conservancy: the example of the Pantanal National Park
(Soc Brasileira Ictiologia, 2017)
Considering the need for the Brazilian government to develop tools for environmental monitoring for biodiversity conservancy purposes in the national protected areas system, this paper focuses on determining reference site ...
