Development and functional morphology of the larval foregut of two brachyuran species from Northern Brazil

Anais da Academia Brasileira de Ciências, 2011
Feeding is an important factor for the successful rearing of larvae of the crab species. Further information on the morphological features of the foregut may to reveal larval feeding behaviour and or/whether there is a lecithotrophy in some or even in ...

Analysing the Ecological Requirements of the Australian Tortoise Beetle Trachymela sloanei (Blackburn, 1897) (Coleoptera: Chrysomelidae) to Determine the Prospects for Its Invasion Process

Journal of Applied Entomology, EarlyView.
ABSTRACT Invasive species pose a serious threat to biodiversity and result in significant economic costs. Although much effort is devoted to understanding invasive processes, some aspects are poorly understood, such as the early stages of invasions and the reasons for invasion failure.

REPRODUÇÃO, DESENVOLVIMENTO EMBRIO-LARVAL E TESTES PRELIMINARES DE TOXICIDADE DE Parablennius pilicornis (CUVIER, 1829)(PISCES: BLENNIIDAE)

Brazilian Journal of Aquatic Science and Technology, 2010
Parablennius pilicornis is a common marine fish widely distributed in the Brazilian coast, and it is characteristic to be the first invertebrate to colonize the artificial substratum. This specie shows many aspects suitable for its use in toxicological tests, such as: resistance to laboratory conditions, adequate size, high reproductive activity ...

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

A fractal pattern of hierarchical genetic population structure in mixed stocks across fish segregated by dams revealed by genomic resources for curimba Prochilodus lineatus

Journal of Fish Biology, EarlyView.
Abstract Genomic resources, new microsatellite markers and a novel observation of a fractal pattern in the genetic population structure are presented for curimba, Prochilodus lineatus, a freshwater migratory model species of South America. Our main goals were to investigate the presence of mixed fish stocks and the effects of damming‐induced ...
