Interspecific association of brown trout (Salmo trutta) with non-native brook trout (Salvelinus fontinalis) at the fry stage [PDF]
The introduction of non-native brook trout (Salvelinus fontinalis) in Europe has led to displacement and decreasing populations of native brown trout (Salmo trutta).

A Tetraploid Amazon Molly, Poecilia formosa [PDF]
Polyploidization is thought to be an important driving force in evolution as it increases the genetic material on which mutation and selection can act. In the Amazon molly, Poecilia formosa, triploid genotypes can be found in the field and frequently arise from diploid breeding stocks, a tetraploid individual, however, was so far never documented. Here,

Read the free Plain Language Summary for this article on the Journal blog. Abstract Flowers with striking colours or scents are often considered to have an advantage in the competition for pollinators. However, if pollinators copy others to avoid exploration costs in changing environments, less attractive flowers may benefit from acquiring early ...

Costs of colour change in fish: food intake and behavioural decisions [PDF]
Many animals, particularly reptiles, amphibians, fish and cephalopods, have the ability to change their body colour, for functions including thermoregulation, signalling and predator avoidance.

Functional response predicts invasiveness but not trophic impact
This comparative analysis challenges the current paradigm that pre‐invasion functional response magnitude serves as a reliable predictor of post‐invasion ecological impact and highlights the need to distinguish between pre‐adaptation in native ranges and realized performance in invaded ecosystems.

Molecular cytogenetic differentiation of paralogs of Hox paralogs in duplicated and re-diploidized genome of the North American paddlefish (Polyodon spathula). [PDF]
BackgroundAcipenseriformes is a basal lineage of ray-finned fishes and comprise 27 extant species of sturgeons and paddlefishes. They are characterized by several specific genomic features as broad ploidy variation, high chromosome numbers, presence of ...

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
