Efeito da intensidade luminosa no desenvolvimento larval do camarão-da-amazônia, Macrobrachium amazonicum

Boletim do Instituto de Pesca, 2014
Investigou-se o efeito de quatro intensidades luminosas (0; 2,8 ± 0,9; 5,46 ± 1,75 e 7,8 ± 2,5 µmol s-1 m-2, aproximadamente 136,5 ± 87,5; 273 ± 43,8 e 390 ± 125 luxes respectivamente) na sobrevivência, na produtividade, no ganho de peso e no desenvolvimento larval de Macrobrachium amazonicum. Cada tratamento teve três repetições.

Abiotic drivers of co‐occurrence and diversity patterns of Calopterygidae species in Amazonian protected freshwaters

Ecological Entomology, EarlyView.
Species co‐occurrences rely on their ability to explore similar or distinct available resources, and possible niche overlap can prevent their presence and establishment in a given site Damselflies of the Calopterygidae family demonstrated negative co‐occurrences in streams inside and outside PAs, highlighting that their ecological similarity is ...

Reduced fecundity associated with Wolbachia infection in a Neotropical drosophilid Redução da fecundidade associada à infecção por Wolbachia em um drosofilídeo Neotropical

Ecological Entomology, EarlyView.
Using multiple infected and uninfected Drosophila sturtevanti lines, we investigated (i) the impact of Wolbachia on fecundity and (ii) its effects relative to antibiotic treatment. Based on over 1680 dissected ovaries, fecundity was similar between infected and uninfected flies.

Where water meets rock: Ecological niches and diversity hotspots of hygropetric beetles in the Neotropics

Ecological Entomology, EarlyView.
First continental‐scale synthesis of hygropetric beetle diversity and distribution across Neotropical highlands. Climatic and topographic gradients structure regional assemblages and niche overlap. Ecological convergence suggests adaptation to similar conditions across disjunct regions.

Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

Ecological Entomology, EarlyView.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

Period of the day drives distinctions in the taxonomic and functional structures of reef fish assemblages

Journal of Fish Biology, EarlyView.
Abstract Circadian processes are key drivers of animal behaviour, influencing patterns of activity, resource partitioning and competition avoidance. Studies evaluating circadian changes on the structure of marine assemblages are lacking, especially for reef fish.

Resistência de genótipos de milho para cultivo em várzeas subtropicais à lagarta-do-cartucho Spodoptera frugiperda Resistance of corn genotypes for subtropical lowland cropping to fall armyworm Spodoptera frugiperda

Ciência Rural, 2008
Spodoptera frugiperda é uma das pragas com elevado potencial para causar perdas econômicas na cultura do milho, no ecossistema de várzeas subtropicais. Com o objetivo de identificar fontes de resistência, foi avaliado, em laboratório, o desenvolvimento ...

Linking rivers, mixing faunas: How artificial connectivity between the Middle and Upper Paraná River basins shapes fish diversity in a tributary of the Itaipu Reservoir, Brazil

Journal of Fish Biology, EarlyView.
Abstract This work aimed to investigate the distribution and occurrence of fish species along the São Francisco Falso Braço Norte (SFFBN) River basin, a tributary of the Middle Paraná River basin now artificially connected to the Upper Paraná ecoregion, to evaluate how such connectivity may affect the biogeographic distribution and regional composition
