MODELACIÓN DE LA RELACIÓN PREDADOR-PRESA PARA LA COMUNIDAD DE MACROINVERTEBRADOS EN EL LITORAL DEL LAGO DE TOTA

Acta Biológica Colombiana, 2023
Los lagos altoandinos son ecosistemas afectados por múltiples presiones antrópicas que alteran la calidad del agua y las comunidades bióticas, siendo los macroinvertebrados acuáticos excelentes bioindicadores para estos ecosistemas.

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family

Fish and Fisheries, Volume 27, Issue 4, Page 781-812, July 2026.
ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

Aproveitamento da macrófita aquática Egeria densa como adubo orgânico Use of aquatic plant (Egeria densa) as an organic fertilizer

Planta Daninha, 2005
Grandes massas de Egeria densa são retiradas dos lagos do sistema hidrelétrico de Paulo Afonso e seu descarte tem sido problemático. O aproveitamento como adubo orgânico foi comparado com o de esterco, em plantio de milho, irrigado, a campo.

Nature of Phytoplankton Communities in the Southern Hemisphere Shallow Lakes, With an Emphasis on the Presence of Submerged Aquatic Vegetation: A Review

Aquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.
ABSTRACT Differences in the ecological stability of shallow lakes are reflected in the functional nature of the distinct phytoplankton communities in the Southern Hemisphere. Recent studies have highlighted growing uncertainties of the previous concepts regarding phytoplankton cosmopolitanism, suggesting these communities may be more regionally ...

Efeito do período de exposição a concentrações de diquat no controle de plantas de Egeria densa, Egeria najas e Ceratophyllum demersum Effect of the period of exposure to diquat concentrations on the control of Egeria densa, Egeria najas and Ceratophyllum demersum

Planta Daninha, 2008
O período de permanência do herbicida na água pode ser influenciado pelo fluxo da água nos reservatórios e pela adsorção a partículas de argilas em suspensão, bem como pela degradação luminosa e por microrganismos.

The social–ecological fabric of freshwater fish management: Accounting for feedback loops in human–fish interactions

Ecosphere, Volume 16, Issue 4, April 2025.
Abstract A holistic view of nature, which situates human relationships and actions within ecosystems, can broaden our understanding of environmental problems and expand the scope and efficacy of potential solutions. Social–ecological systems (SES) research attempts to take this broad perspective.
