Subindividual variability in sea pens (Octocorallia: Pennatulacea) Variabilidad subindividual en plumas de mar (Octocorallia: Pennatulacea)

Abstract

Las comparaciones entre plantas e invertebrados coloniales modulares sésiles ofrecen interesantes paralelismos entre los planes corporales de las plantas y los animales, tras millones de años de evolución divergente. Entre estos parale-lismos podría estar la existencia y distribución de la heterogeneidad intraindividual en los rasgos de los órganos, también denominada variabilidad subindividual. La variabilidad subindividual es importante cuantitativamente y tiene múltiples consecuencias para las plantas individuales, las poblaciones y las comunidades, así como para los animales consumidores. Mas, ¿podría ocurrir un proceso similar de variabilidad subindividual en plumas de mar, que tienen una arquitectura modu-lar similar a la de las plantas? En la literatura de invertebrados marinos se sabe muy poco sobre la presencia y la magnitud de la variabilidad subindividual en los organismos modulares. Este estudio proporciona por primera vez una evaluación cuantitativa de la variabilidad subindividual en las plumas de mar, analizando ciertas características biométricas de estruc-turas reiteradas que presumiblemente tienen alguna función ecológica, y ofrece una primera comparación de los niveles cuantitativos de variación subindividual entre las plantas y las plumas de mar

Comparisons between plants and sessile modular colonial invertebrates offer interesting parallelisms between plant and animal body plans after millions of years of divergent evolution. Among these parallelisms might be the existence and distribution of intraindividual heterogeneity in organ traits, also named subindividual variability. Subindividual variability is quantitatively important and has many consequences for plant individuals, populations and communities, and for animal consumers as well. However, could a similar process of subindividual variability occur in sea pens, which have a modular architecture similar to that of plants? In the literature of marine invertebrates very little is known about the presence and magnitude of subindividual variability in modular organisms. This study provides for the first time a quantitative assessment of subindividual variability in sea pens, analysing certain biometric features of reiterated structures that presumably have some ecological function, and offers an initial comparison of quantitative levels of subindividual variation between plants and sea pens.
