| development from metacercaria to adult of a new species of maritrema (digenea: microphallidae) parasitic in the kelp gull, larus dominicanus , from the patagonian coast, argentina. | maritrema madrynensis n. sp. is described from the patagonian coast, argentina, based on naturally obtained adults from the kelp gull larus dominicanus and cultured metacercariae from the crab cyrtograpsus altimanus . the new species fits into the "eroliae complex" and can be distinguished from other related species mainly in shape, size, and distribution of the spines on the cirrus and vitellarium in a complete ring in all specimens. based on morphological and morphometric features of the natur ... | 2010 | 20496960 |
| combined effects of uvr and temperature on the survival of crab larvae (zoea i) from patagonia: the role of uv-absorbing compounds. | the aim of our study was to assess the combined impact of uvr (280-400 nm) and temperature on the first larval stage (zoea i) of three crab species from the patagonian coast: cyrtograpsus altimanus, c. angulatus, and leucippa pentagona. we determined the survival response of newly hatched zoea i after being exposed for 8-10 h under a solar simulator (hönle sol 1200) at 15 and 20 degrees c. there was no mortality due to photosynthetic active radiation (par, 400-700 nm) or ultraviolet-a radiation ... | 2010 | 20559492 |
