“…Although there are various definitions of alien species (Falk-Petersen et al, 2006), the most widely accepted one is that of species, which, by human agency, have managed to overcome physical barriers and colonize new regions beyond their natural range. In a rapidly changing world, it is often difficult to attribute a new arrival to a region to human activities.…”

“…Then they were fixed in 70% alcohol and deposited in the Benthic Ecology Laboratory reference collection (França & Callisto 2007), Institute of Biological Sciences, Federal University of Minas Gerais. We considered alien species as those that occurred outside their past or present natural geographic range, and whose dispersal is aided by humans (Falk-Petersen et al 2006). …”

Reservoirs are artificial ecosystems with multiple functions having direct and indirect benefits to humans; however, they also cause ecological changes and influence the composition and structure of aquatic biota. Our objectives were to: (1) assess the environmental condition of Nova Ponte Reservoir, Minas Gerais state, southeastern Brazil; and (2) determine how the aquatic biota respond to disturbances. A total of 40 sites in the littoral zone of the reservoir were sampled to characterize physical and chemical habitat, land use, and benthic macroinvertebrate and fish assemblages. The predominant type of land cover near the reservoir was natural vegetation. A total of 29 fish species and 39 macroinvertebrate taxa were collected, including eight alien species. Most sites had intermediate levels of human disturbance, however, high levels of degradation were associated with high proportions of alien species. Disturbances at multiple scales may alter natural patterns and processes, leading to environmental changes and damaging biological communities. Our results reinforce the importance of assessing reservoir ecological conditions at several scales. The study of land use, littoral zone physical habitat characteristics, water quality, and assemblage structure set the ground for proposing actions to rehabilitate and conserve aquatic ecosystems. Keywords: reservoirs, water quality, bioindicators, physical habitat, environmental quality.MARTINS, I., SANCHES, B., KAUFMANN, P.R., HUGHES, R.M., SANTOS, G.B., MOLOZZI, J., CALLISTO, M. Avaliação Ecológica de um reservatório no sudeste do Brasil.http://dx.doi.org/10.1590/1676-06032015006114Resumo: Reservató rios sã o ecossistemas artificiais com mú ltiplas funçõ es e que oferecem benefícios diretos e indiretos ao homem; no entanto, também causam mudanças ecoló gicas e influenciam a composiçã o e estrutura da biota aquá tica. Os objetivos deste estudo foram: (1) avaliar a condição ambiental do reservató rio de Nova Ponte, Estado de Minas Gerais, sudeste do Brasil; e (2) verificar se a biota aquá tica responde aos distú rbios. No total, 40 sítios amostrais na regiã o litorâ nea do reservató rio foram amostrados para caracterizar os habitats físicos e químicos, cobertura e uso do solo, assembleias de macroinvertebrados e peixes. Vegetaçã o natural de cerrado foi o tipo predominante de cobertura do solo no entorno do reservató rio. 29 espécies de peixes e 39 taxa de macroinvertebrados bentô nicos foram coletadas, incluindo oito espécies exó ticas. A maioria dos sítios amostrais possui níveis intermediá rios de distú rbio antró pico, porém o aumento de alteraçõ es antró picas foi associado ao aumento do nú mero e abundâ ncia de espécies exó ticas. Distú rbios em mú ltiplas escalas podem alterar os padrõ es e processos naturais, levando a mudanças ambientais e nas comunidades bioló gicas. Nossos resultados reforçam a importâ ncia de avaliar as condiçõ es ecoló gicas do reservató rio em vá rias escalas. O estudo do uso e cobertura do solo, características de habitats físic...

“…Others go a step further and estimate the probability of a species becoming invasive. Unfortunately, there is no consensus in the scientifi c community as to what ' invasive ' actually means (Falk -Petersen et al 2006 ;Colautti & Richardson 2009 ). Although the policy interpretation of invasive assumes a negative impact (IUCN 2000 ), many scientists do not agree with this defi nition and use the term to describe species capable of becoming widespread rather than causing damage (Richardson et al 2000 ).…”
