Development of a Trait-Based Risk Assessment to Minimise the Impacts of Trout on New Zealand Native Fishes. [PDF]
Ecol EvolA trait‐based risk assessment framework was developed to identify New Zealand's native freshwater fish most vulnerable to the pressures of valued sports fisheries (trout). We further examine where the distributions between at‐risk species and trout are likely to overlap, providing priority locations for conservation managers to investigate further and ...

Invasive predatory fish occupies highest trophic position leading to expansion of isotopic niches in a riverine food web. [PDF]
EcologyAbstract Invasive species are drivers of ecological change with the potential to reshape the structure and function of terrestrial and aquatic ecosystems. The invasive flathead catfish (Pylodictis olivaris) is an opportunistic predator that has established a rapidly growing population in the Susquehanna River, Pennsylvania, USA, since they were first ...

ANÁLISE DA ATIVIDADE NUCLEAR DE DEZ GALÁXIAS COM ANEL POLAR
Revista UniVap, 2013 O acúmulo de massa, proveniente do processo de interação que forma as galáxias com anel polar, é um fator que favorece as condições necessárias para disparar atividades nucleares não térmicas. Esse fato fomentou a análise química de dez galáxias com anel

Interactive Effects of Copper Contamination and Salinization Across Multiple Genotypes of <i>Daphnia magna</i>. [PDF]
Ecol EvolThis study examined how Daphnia magna genotypes from US and French populations respond to copper and salinity stress, alone and in combination. US genotypes were generally more sensitive but showed improved survival under combined stress, indicating possible cross‐tolerance mechanisms.
