“…Apart from differences in data quality among studies (type II error) and spatiotemporally linked data biases [in one case out of three in which a temporal subset (seasonality) was available, we demonstrated that the temporal dimension of the analysis affected the structure of the dataset], we should also mention that Poisson errors can obscure possible structures in small matrices (Luiselli 2008b). In our study case, this potential bias is likely of only very minor relevance, as small matrices (2 9 6 cells or less) were found only in three studies (Lescure 1971;Lajmanovich 1995;Low and Törok 1998), and none of these produced nonrandom structure.…”

“…Uno de los temas más estudiados en ecología ha sido el determinar cómo las especies difieren en el uso de los recursos (Luiselli 2008). Por lo general se establece entre miembros de grupos de especies simpátricas que cuentan con alguna semejanza en cuanto a sus papeles o roles tróficos (Schoener 1986).…”

“…Un problema con los estudios del reparto de recursos es que difieren en cuanto a causas y patrones entre grupos de diferentes organismos, por lo que se dificulta hacer generalizaciones. Sin embargo, para ciertos grupos de animales estos estudios son abundantes (Luiselli 2008), por ejemplo, en anfibios y reptiles (Toft 1985). Para el caso de estudios realizados en México que involucran el reparto de recursos, sólo por mencionar algunos, se encuentran Lemos-Espinal & Franco-López (1984), Altamirano & García (1989), Altamirano et al (1990Altamirano et al ( , 1992, Lara & Castro-Franco (1991), Ortega et al (1992Ortega et al ( , 1994Ortega et al ( , 1995, Álvarez y Sarabia (2006Álvarez y Sarabia ( , 2007, García de la Peña et al (2007) y Macip-Ríos & Muñoz-Alonso (2008.…”

“…Se efectuó una revisión de la literatura (Tabla 1), para luego realizar un meta-análisis según la descripción de Luiselli et al (2007) y Luiselli (2008a, 2008b. Para esto se consideró la revisión en la literatura de los trabajos sobre copépodos intermareales de los territorios insulares chilenos (Goddard, 2003(Goddard, , 2006 y de la zona de Montemar (Goddard & Zúñiga, 1995), que se basaron en colectas de especímenes adultos en los sitios antes mencionados.…”
