Níveis iônicos e hidratação muscular comprovam as estratégias de osmorregulação entre o caranguejo osmoconformador (Hepatus pudibundus) osmorregulador (Callinectes danae). Os epitélios das brânquias estão em contato direto com a água, desempenhando um papel na (brânquias posteriores). Através da microscopia óptica (O.M.) foi possível observar algumas diferenças histologia branquial, como tecido...

Ficus hispida and racemosa are Moraceae species that commonly grow on riverbanks. Actions to propagate generative plants required more observation due mutualistic symbiosis between F. with Ceratosolen solmsi fusciceps as pollinating insects. This study aimed obtain data seed production, germination, the interaction of Research activities included extraction, germination testing, calculation num...

The juvenile development of Callinectes danae was investigated from megalopae obtained in neuston samples at Ubatuba, São Paulo, Brazil. The individuals were raised in the laboratory under constant temperature (25 ± 1°C), filtered sea water from the collection location (35‰), and natural photoperiod. Newly hatched Artemia sp. nauplii were offered as food on a daily basis and ornamental-fish foo...

1. We observed that the dragonfly species Sympetrum flaveolum, S. striolatum, S. sanguineum, S. meridionale and S. danae were attracted by polished black gravestones in a Hungarian cemetery. 2. The insects showed the same behaviour as at water: (i) they perched persistently in the immediate vicinity of the chosen gravestones and defended their perch against other dragonflies; (ii) flying indivi...

methanol 70% extract of bauhinia racemosa aerial parts was tested for antimicrobial activity against different bacterial and fungal strains and for antioxidant activity and also total content of polyphenols with phytochemical analysis of the extract was determined. the results have showed that the extract has a significant antimicrobial activity, it inhibited the growth of bacillus subtilis and...
