“…A importância de áreas de proteção ao redor de rios e lagos para promover a qualidade das águas é amplamente reconhecida (Anbumozhi et al, 2005;Tundisi et al, 2008;Galatto et al, 2011;Nielsen et al, 2012;Pratt & Chang, 2012), destacando-se a importância destas na diminuição do aporte de sedimentos, filtragem de nutrientes e agrotóxicos de áreas cultivadas.…”

“…Sobretudo nessas últimas, os fluxos de nutrientes e agrotóxicos nas águas de percolação e de escoamento passam por filtragem química e por processamento microbiológico, o que reduz sua turbidez e a presença de contaminantes (Anbumozhi et al, 2005;Phua & Minowa, 2005), o que evidencia a importância dessas áreas para a manutenção da qualidade das águas.…”

Resumo -O objetivo deste trabalho foi determinar a relação dos indicadores de qualidade da água com o regime de chuvas e os padrões de uso da terra. Foram avaliadas quatro bacias hidrográficas e suas respectivas áreas de preservação permanente (APPs), fontes do reservatório Alagados, no Estado do Paraná. O uso dos solos nas bacias e nas APPs foi mapeado em ambiente de sistema de informações geográficas, e os padrões resultantes foram avaliados quanto ao índice de qualidade das águas (IQA) e ao regime pluvial. A qualidade das águas foi menor nos períodos de verão, quando há maior precipitação e manejo mais intensivo dos solos, com presença de maiores superfícies cultivadas na paisagem. A área total cultivada nas APPs teve efeito negativo sobre a qualidade das águas. Diferenças topográficas, geomorfológicas e pedológicas, bem como sua influência nos padrões de uso dos solos, foram discutidas para possível explanação dos valores observados de IQA nas bacias. A variabilidade dos padrões de IQA entre as bacias, bem com os valores extremos observados de acordo com as estações do ano, evidencia a necessidade de gerenciamento do uso das terras, particularmente no âmbito das APPs, para que sejam mantidos padrões desejáveis de vazão e qualidade das águas do manancial.Termos para indexação: agricultura intensiva, áreas de preservação permanente, recursos hídricos, planejamento territorial, poluição não pontual. Indicators of water quality and land usage patterns in watersheds in the state of Paraná, BrazilAbstract -The objective of this work was to determine the relationship of water quality indicators with rainfall regime and land use patterns. Four watersheds and their respective permanent protected areas (APPs), sources of the Alagados reservoir, in the state of Paraná, Brazil were evaluated. Land use at basin level and in the APPs were mapped in a geographic information system environment, and the resulting patterns were evaluated as to their relation with the water quality index (IQA) and rainfall regime. Water quality decreased in the summer periods, when higher average rainfall and more intensive land management were present, with larger cultivated areas in the landscape. Total cultivated area in the APPs had negative effect on water quality. Differences in topography, geomorphology, and soil types, as well as their effect on land use patterns, were discussed as a potential explanation for the observed values of the IQA in each basin. The variability of the IQA patterns among watersheds, as well as the extreme values observed according to the season, highlights the demand for land use planning, particularly within the APPs, in order to ensure desirable patterns of water flow and quality in the wellspring.

“…Pilliod et al [57] proposed three responses of different amphibians to fire and fire-related changes in habitat over time: (1) species that are at first sensitive to disturbance benefit in the long-term from productivity increases; (2) species experience an increase in density due to predator and competitive release as well as opening the forest canopy; and (3) rare, sensitive species with low densities or limited distribution are negatively affected and their populations drop quickly. As demonstrated by those predictions, the impact of prescribed fires on salamander populations in riparian forests is not wholly negative.…”

“…They play an important role in forest landscapes, and forested riparian strips can be used by landowners to reduce water pollution from agricultural practices [1,2] and by forest managers to enhance ecosystem function [3,4]. Riparian forests perform many important environmental services, such as providing core habitat for a diverse variety of organisms, controlling in-stream processes, moderating shade and water temperature, acting as corridors for dispersal and foraging, supporting high soil moisture, and modifying the amount of nutrient export from watersheds [3,5,6].…”

Salamanders and riparian forests are intimately interconnected. Salamanders are integral to ecosystem functions, contributing to vertebrate biomass and complex food webs in riparian forests. In turn, these forests are critical ecosystems that perform many environmental services, facilitate high biodiversity and species richness, and provide habitat to salamander populations. Due to the global decline of amphibians, it is important to understand, as thoroughly and holistically as possible, the roles of environmental parameters and the impact of human activities on salamander abundance and diversity in riparian forests. To determine the population responses of salamanders to a variety of environmental factors and anthropogenic activities, we conducted a review of published literature that compared salamander abundance and diversity, and then summarized and synthesized the data into general patterns. We identify stream quality, leaf litter and woody debris, riparian buffer width, and soil characteristics as major environmental factors influencing salamander populations in riparian forests, describe and explain salamander responses to those factors, and discuss the effects of anthropogenic activities such as timber harvest, prescribed fires, urbanization, road construction, and habitat fragmentation. This review can assist land and natural resource managers in anticipating the consequences of human activities and preparing strategic conservation plans. OPEN ACCESSForests 2014, 5 2680

“…Pesticides, synthetic fertilizers, sewage and animal wastes from feedlots enter rivers along different routes with groundwater and storm-water runoff (Berka et al 2001). The high level of nitrates and phosphates delivered from point and area sources of contamination may be significantly reduced by plants growing in the riparian zone, particularly riparian forests (Naiman & Dacamps 1997, Anbumozhi et al 2005. Riparian plant communities moderate water temperature, regulate river flow and control bank erosion (Palink et al 2000).…”

The presented study describes the plant species diversity within the terrestrial-water ecotone in relation to the land-use form in a river valley. The study was performed in a lowland river valley where the main forms of riparian zones are partially urbanized, forested and agricultural; the latter being most commonly observed in the investigated region. The present study examines the vascular flora of ecotones where more than 100 plant species were identified. Ecological indices were calculated at all sampling sites based on Zarzycki's ecological values and biodiversity indices. In addition, the aim of the study was to identify the relationships between the physico-chemical parameters of the water and the floristic indicators in the neighbouring ecotones.
