The Pelagic Propagule's Toolkit
The pelagic propagule’s toolkit: An exploration of the morphology, swimming capacity and behaviour of marine invertebrate propagules by © Emaline M. Montgomery A Dissertation submitted to the School of Graduate Studies in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Marine Biology, Department of Ocean Sciences, Faculty of Science, Memorial University of Newfoundland June 2017 St. John’s, Newfoundland and Labrador Abstract The pelagic propagules of benthic marine animals often exhibit behavioural responses to biotic and abiotic cues. These behaviours have implications for understanding the ecological trade-offs among complex developmental strategies in the marine environment, and have practical implications for population management and aquaculture. But the lack of life stage-specific data leaves critical questions unanswered, including: (1) Why are pelagic propagules so diverse in size, colour, and development mode; and (2) do certain combinations of traits yield propagules that are better adapted to survive in the plankton and under certain environments? My PhD research explores these questions by examining the variation in echinoderm propagule morphology, locomotion and behaviour during ontogeny, and in response to abiotic cues. Firstly, I examined how egg colour patterns of lecithotrophic echinoderms correlated with behavioural, morphological, geographic and phylogenetic variables. Overall, I found that eggs that developed externally (pelagic and externally-brooded eggs) had bright colours, compared -
Madreporites of Ophiuroidea: Are They Phylogenetically Informative?

Whereas in the family Ophiuridae (as in the clades B onomy. However, it is known that there is diversity in the and C), the oral interradial shields are regularly formed. madreporite structure. But are the ophiuroid madreporites Contrary to this, the multiple madreporites and numerous phylogenetically informative? To check this hypothesis, we madreporic pores appear to have evolved several times in investigated the structure of the madreporite of 33 species different clades. Hence, the hypothesis that madreporite of brittle stars from 4 families of Euryalida and 12 families morphology is phylogenetically informative must be of Ophiurida. The fixed specimens were processed with rejected since madreporites are highly homoplasious. sodium hypochlorite using the standard procedure and then studied using SEM. If we combine our results with the Keywords Ophiuroids Á Ophiuroidea Á Madreporite Á modern phylogenetic data about brittle stars (O’Hara et al.

Buenos Aires, 2010 Crecimiento, reproducción y alimentación del ofiuroideo Ophioplocus januarii (Lütken, 1856) (Echinodermata: Ophiuroidea) en costas de Patagonia, Argentina RESUMEN Se estudiaron diversos aspectos de la biología del ofiuroideo Ophioplocus januarii de una población de playa Villarino en el golfo San José (42º24'S; 64º17'O) entre 2005 y 2009. La morfología general del cuerpo y la morfología mandibular se describen a partir de los ejemplares capturados. El desarrollo de la placa dental y la formación de nuevos dientes ocurren tanto en sentido ventral como dorsal, por primera vez descrito para un ofiuroideo. El estudio de la musculatura mandibular permite describir y estimar los movimientos de las mandíbulas. La morfometría entre el tamaño del cuerpo y el largo de la placa dental y de los dientes presentan una relación funcional del tipo potencial, siendo posible estimar el tamaño corporal en base a mediciones en las mandíbulas. Los estudios de marcado químico empleando calceína fueron exitosos, quedando evidenciadas las zonas de calcificación mediante una marca fluorescente. Empleando estas técnicas de marcado químico la estructura que mejor indica el crecimiento en esta especie es la mandíbula. -
