The threat posed by invasive non-native species worldwide requires a global approach to identify which introduced are likely pose an elevated risk of impact native and ecosystems. To inform policy, stakeholders management decisions on threats aquatic ecosystems, 195 assessors representing 120 assessment areas across all six inhabited continents screened 819 from 15 groups organisms (freshwater, brackish, marine plants animals) using the Aquatic Species Invasiveness Screening Kit. This...
Length–weight (LWR) and length–length relationships (LLR) are presented for 135 freshwater fish species sampled by several types of fishing gear between April 2012 July 2014 in the middle lower Xingu River Basin, northern Brazil. The report represents first references on LWRs LLRs 114 119 species, respectively, also provides a new maximum size 96 species.
The observation of the effects, generally negatives, caused to environment by human activities has led creation standards and basic conditions for that an enterprisecan take ownership aspecificarea, aiming does not cause significant changes environment, such as preservation natural resources. In this context, methods Environmental Impact Assessment (EIA) had been formulated, which excellence are dedicated make predictions effects a specific project short, medium long term. present work...
This study estimates the main biological parameters, including growth rates, asymptotic length, mortality, consumption by biomass, yield, and for most abundant fish species found on middle Xingu River, prior to construction of Belo Monte Dam. The specimens collected in experimental catches were analysed with empirical equations length-based FISAT methods. For 63 studied, high rates (K) natural mortality (M) related early sexual maturation low longevity. predominance short life cycles a...
Register of a gynandromorph Euglossa pleosticta (Hymenoptera, Apidae). Here we provide description with partial bilateral phenotypic asymmetry. The specimen was collected by cineol baittrap at Parque Estadual São Camilo, conservation unit in western Paraná. bee has mostly female phenotype, except the right half its head, including presence 11 flagellomeres, ivory markings on scape and parocular area, pilosity galea, deformed male characteristics mid hind tibiae legs.
Baseado na necessidade de se criar formas alternativas no sistema manejo culturas agricolas, torna-se relevante o estudo da atividade quimica metabolitos secundarios existentes em plantas conhecidas nos ecossistemas agricolas do Brasil. Os compostos provenientes metabolismo secundario das apresentam propriedades semelhantes a um composto quimico sintetico, podendo desta forma substitui-lo, reduzindo-se utilizacao destes e seus impactos. A mais estudada com este fim alelopatia, que compreende...
As plantas medicinais representam uma alternativa de tratamento e/ou prevenção doenças grande importância na vida das pessoas, não somente por sua eficácia ação terapêutica, mas também se inserir simultaneamente como parte da cultura um povo. Neste contexto, o presente trabalho teve objetivo realizar levantamento do uso entre os funcionários Universidade Federal Paraná, Palotina, Brasil. Foram aplicados questionários semiestruturados sobre a utilização aos docentes, técnico-administrativos e...
Environmental characteristics of an invaded environment can predict the invasion success a species, depending on its habits and life strategies. Cichla kelberi is visual voracious predator introduced in Upper Paraná River floodplain, area that suffers with several upstream dams caused many environmental changes over years (e.g. increased water transparency). As this species pre-adapted to environments presents high transparency, our main goal was test hypothesis variables related underwater...
The length-weight relationship (LWR) was evaluated in six fish species occurring the Rio Morato, which is located east state of Paraná, Brazil, well-preserved areas Atlantic Forest. fishes were collected every 2 months from November/2016 to October/2017 and fishing equipment used consisted dragnets, mesh sieves gillnets. specimens weighed measured laboratory. mean growth coefficients obtained ranged 2.5 3.2, confirming range describe literature.
Abstract The South America ichthyofauna encompasses the highest diversity of world, however is highly threatened by anthropogenic actions. fish fauna nine low-order streams, tributaries Piquiri River and impacted aquaculture, agriculture urbanization were sampled in present study. Samplings done quarterly from December 2017 to September 2018 at three sites each stream, using a portable electric fishing device 50-meter segments. A total 14,507 individuals collected, belonging six orders, 20...
The implementation of conservation units is an important strategy to conserve biodiversity, however, their consolidation as effective mechanism for protecting natural resources faces several challenges. Therefore, the objective this work was evaluate effectiveness and management nine in west northwest regions state Paraná, Brazil, by application questionnaires, interviews with managers these areas. All evaluated had insufficient number employees meet demand, plan 56% 89% that a were...
