The larval development of Phylladiorhynchus pusillus is described from plankton specimens from the coast of Easter Island (27°20′S, 109°40′W). The morphological description of five zoeae and megalopae are given, comparing the meristic characters of the larvae with those of other galatheids, and the differences that allow their discrimination. The first larval stage of P. pusillus differs from the larvae described for the genus Galathea, by the slight segmentation between the basi and exopodite of the third maxilliped, in addition to the presence of four plumose setae at the distal end of the exopodite. The second zoea can also be differentiated because the number of plumose setae is maintained at the distal end of the exopodite, with two setae less than its congeners of the genus Galathea. The scientific name of the species is discussed, which is one of the two Galatheidae species from the coasts of Chile, according to Ahyong et al. (2010) classification. The most notable difference of the examined zoeae, concerning the other species, and what is described for P. integrirostris, is the slight segmentation between the exopodite and the basipodite of the third maxilliped and the presence of four plumose setae on the distal end of the exopodite.

La apicultura está en desarrollo en Uruguay, donde más del 90% de la producción es vendida para exportación. El objetivo de este trabajo fue investigar la relación entre el origen botánico de la miel y la conductividad. La conductividad es una medida indirecta del contenido de cenizas y desde un punto de vista nutricional es un indicador de la composición mineral de la miel, importante suplemento de la dieta del hombre. Se estudiaron cuadros de colmenas de diferentes áreas geográficas de Uruguay. La miel se extrajo mediante prensa en laboratorio y filtrado con tejido sintético. Se analizaron el color, la humedad, la conductividad eléctrica y la melisopalinología. Las mieles más oscuras presentaron mayores valores de conductividad. La mayor conductividad fue de bosque nativo, bosque de Eucalyptus spp. y de mielada. La miel de monte nativo uruguayo es única en el mundo, un sabor tipo y altos niveles de conductividad, lo que la hace una buena fuente de minerales.

The spiny lobster Panulirus pascuensis stands out among the endemic species of Easter Island, due to its cultural and economic importance. A total of 16 microsatellite loci were characterized in 18 individuals, 9 of which were polymorphic. The mean number of alleles per locus was 3.44 (2-6) and the observed heterozygosity ranged from 0.11 to 0.93. None of the loci exhibited significant linkage disequilibrium or departures from HWE. These new microsatellites will be used to obtain information about migration, population structure and genetic diversity of P. pascuensis in order to improve the future sustainable management and conservation plans.
