Abstract The introduction of the amphipod Dikerogammarus villosus in European fresh waters is to date recognized as a threat integrity invaded communities. Predation by D. on native benthic invertebrates assumed key determinant its ecological impact, yet available information describe species primary consumer well carnivore depending local conditions. Here, we assessed trophic position (TP) Lak...

A tuberculose é uma das doenças infectocontagiosas de maior importância no Brasil e mundo. Afeta forma importante populações em situação vulnerabilidade social econômica. O objetivo deste estudo foi realizar um levantamento do número casos notificados nos últimos 10 anos (2011 a 2021), avaliar os fatores que afetam transmissão, bem como discutir o tratamento padrão com fitoterápicos. epidemioló...

Pteridophytes are not as well characterized at the molecular and biochemical level as some higher plants. However, to aid conservation efforts (4), there is growing interest in understanding the population biology of many fern species that are under threat. DNAbased studies offer excellent tools for such work, but are hampered in ferns by difficulties in obtaining good-quality DNA from sufficie...

Chloroplasts change their positions in the cell depending on the light conditions. In the dark, chloroplasts in fern prothallia locate along the anticlinal wall (dark position). However, chloroplasts become relocated to the periclinal wall (light position) when the light shines perpendicularly to the prothallia. Red light is effective in inducing this relocation in Adiantum capillus-veneris, an...
