A novel statistical analysis of cnidocysts in acontiarian sea anemones (Cnidaria, Actiniaria) using generalized linear models with gamma errors

Sea Anemones through X-Rays: Visualization of Two Species ofDiadumene(Cnidaria, Actiniaria) Using Micro-CT

“…The presence of these two nematocysts in the acontia has since been confirmed for T. errans (Excoffon and Zamponi, 1993) and D. lineata Acuña et al, 2004). The recovered position of D. lineata within Diadumenidae in recent phylogenetic analyses (e.g., Rodríguez et al, 2012Rodríguez et al, , 2014Lauretta et al, 2014;Grajales and Rodrí-guez, 2016) supports Manuel's (1981) hypothesis that an extra category of p-mastigophores did not warrant the erection of the family Haliplanellidae, but does not support the maintenance of D. lineata in a separate genus.…”

Evolução de Staurozoa (Cnidaria): inferências moleculares, morfológicas e de cnidoma

“…Cnidae, or cnidocysts, are complex organelles synapomorphic for the phylum Cnidaria Acuña et al, 2004;. The inventory of all types of cnida presented by a cnidarian at a certain stage of its life history is known as its cnidome (Weill, 1934).…”

“…The inventory of all types of cnida presented by a cnidarian at a certain stage of its life history is known as its cnidome (Weill, 1934). There are three types of cnidae: nematocysts, spirocysts, and ptychocysts (Bedot, 1896;Weill, 1934;Mariscal, 1974;Mariscal et al, 1977;Acuña et al, 2004;). Nematocysts, the most common and diverse type of cnida, are present in all cnidarian species, and total at least 30 different types (Weill, 1934;).…”

“…Description of nematocysts is considered important information for taxonomic studies , although sometimes their value in identifying species is questioned (Acuña et al, 2004). Cnidomes have been studied in detail for some hydrozoans, and many reviews corroborate the taxonomic relevance of these observations (e.g., Östman, 1979a, 1979b, 1982Cornelius & Östman, 1987;Gravier-Bonnet, 1987;Marques et al, 2000;Marques, 2001;Peña Cantero et al, 2007), as well for Scyphozoa (viz.…”

Revisão sistemática do gênero Bunodosoma Verrill, 1899(Cnidaria: Actiniaria: Actiniidae) e estudo de populações do Atlântico Sul

“…Reft et al, 2009), quanto com relação à análise das medidas, com a utilização de tratamentos estatísticos mais adequados como os Modelos Lineares Generalizados (em inglês GLM) (Nelder & Wedderburn, 1972) (e.g. Acuña et al, 2004). Esses dois tipos de abordagens ainda são pouco utilizadas nos estudos dentro do grupo e, portanto, sua eficácia na resolução dos problemas do estudo do cnidoma ainda não é bem conhecida.…”
