What Can We Learn from Confusing Olivella Columellaris and O

What can we learn from confusing Olivella columellaris and O. semistriata (Olivellidae, Gastropoda), two key species in panamic sandy beach ecosystems? Biota Neotrop. 12(2): http://www.biotaneotropica.org.br/v12n2/ en/abstract?article+bn02112022012 Abstract: Olivella columellaris (Sowerby 1825) and O. semistriata (Gray 1839) are suspension‑feeding, swash‑surfing snails on tropical sandy beaches of the east Pacific. While they often are the numerically dominant macrofaunal element in their habitats, their biology is poorly understood; the two species actually have been confused in all of the few publications that address their ecology. Frequent misidentifications in publications and collections contributed also to an overestimation of the geographic overlap of the two species. To provide a sound taxonomic basis for further functional, ecological, and evolutionary investigations, we evaluated the validity of diagnostic traits in wild populations and museum collections, and defined workable identification criteria. -
Characterization of Arm Autotomy in the Octopus, Abdopus Aculeatus (D’Orbigny, 1834)
Characterization of Arm Autotomy in the Octopus, Abdopus aculeatus (d’Orbigny, 1834) By Jean Sagman Alupay A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Integrative Biology in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Roy L. Caldwell, Chair Professor David Lindberg Professor Damian Elias Fall 2013 ABSTRACT Characterization of Arm Autotomy in the Octopus, Abdopus aculeatus (d’Orbigny, 1834) By Jean Sagman Alupay Doctor of Philosophy in Integrative Biology University of California, Berkeley Professor Roy L. Caldwell, Chair Autotomy is the shedding of a body part as a means of secondary defense against a predator that has already made contact with the organism. This defense mechanism has been widely studied in a few model taxa, specifically lizards, a few groups of arthropods, and some echinoderms. All of these model organisms have a hard endo- or exo-skeleton surrounding the autotomized body part. There are several animals that are capable of autotomizing a limb but do not exhibit the same biological trends that these model organisms have in common. As a result, the mechanisms that underlie autotomy in the hard-bodied animals may not apply for soft bodied organisms. A behavioral ecology approach was used to study arm autotomy in the octopus, Abdopus aculeatus. Investigations concentrated on understanding the mechanistic underpinnings and adaptive value of autotomy in this soft-bodied animal. A. aculeatus was observed in the field on Mactan Island, Philippines in the dry and wet seasons, and compared with populations previously studied in Indonesia. -

The figures referred to after the names of the species, under the genera, are those given in " The Figures of Molluscous Animals, for the Use of Students, by Maria Emma Gray, 3 vols. 8vo, 1850 to 1854 ;" or when the species has been figured since the appear- ance of that work, in the original authority quoted.

Tips & Tricks Voor Auteurs
Tips & Tricks voor auteurs Heel wat auteurs schrijven waardevolle artikels voor Gloria Maris, en dat mogen gerust goede artikels genoemd worden. Hieronder volgen nog enkele tips en tricks i. v. m. regelgeving en moderne aanbevelingen om van hun goed artikel een geweldig artikel te maken en zodoende de kwaliteit en internationaal aanzien van Gloria Maris mee te helpen opkrikken. 1. Volg altijd de provisies van de Code betreffende beschikbaarheid, toegestane werken, binomen / trinomen, synonymie, homonymie, typificatie en de ethische code. (kortom: volg de Code) 2. Een goed artikel wordt geweldig door aandacht voor details: a. TIP: Formatteer steeds je artikel in een bepaalde taal (voorkeur: Engels (UK)) voordat je begint. i. LET OP: Microsoft Word heeft slechte gewoonten in het zelf aanpassen van taal naargelang wat je typt of de stijl ervan. TIP: Als je de “Markup” of “Track Changes” aan zet, kan je zien wanneer Word zelf zulke dingen doet, en kan je dat bijsturen. b. Abstract en Key words zijn waardevolle elementen. i. TIP: Schrijf deze twee als laatse, en denk bij het Abstract aan “korte inhoud”. ii. TIP: Woorden die reeds in de titlel gebruikt werden, dienen niet expliciet meer opgenomen te worden in de Key Words, tenzij er geen andere voorhanden zijn. vb: Indien in de titel reeds “Mollusca: Gastropoda” staat, dient dit niet meer herhaald te worden, en kan je de Key Words opbouwen “van boven naar beneden”: vb Hogere classificatie, families, genera, species, localiteiten, auteurs: Caenogastropoda, Cerithioidea, Turritellidae, Cerithiidae, Turritella, Haustator, terebra, cochlea, Red Sea, Arabian Sea, Shopland, Abubakr. c.

Macrofaunal Community Structure and Zonation of an Ecuadorian Sandy Beach (Bay of Valdivia)

Box 09-01-5863, Guayaquil, Ecuador Corresponding author : Thomas Vanagt, e-mail : [email protected] ABSTRACT. The sandy beach macrofauna of the Bay of Valdivia (Ecuador) was sampled in August-September 1999 along six replicate transects between the high and low water line. The sediment consisted of well-sorted, fine to medium sand. Taking into account the dimensionless fall velocity (Ω) and the relative tidal range, the beach was characterized as an exposed, low tide terrace - rip beach. The distribution of the macrofauna was mainly determined by the elevation on the beach. Thirty-one taxa were found throughout the study, varying between 10 and 22 taxa per transect. Molluscs were the most dominant taxon (overall average : 285 ind/m2, max. : 2135 ind/m2), followed by crustaceans. The gastropod Olivella semistriata (overall average : 243 ind/m2, max. : 2131 ind/m2) was the most abundant species. The crustaceans were the most diverse taxon (10 spp.); Haustorius sp., Excirolana braziliensis and Emerita rathbunae were the most abundant species. -
Sambaquis As a Proxies of Late Holocene Mollusk Diversity on the Coast of Rio De Janeiro, Brazil
Archaeofauna 28 (2019): 105-118 Sambaquis as a proxies of late Holocene mollusk diversity on the coast of Rio de Janeiro, Brazil Los Sambaquis como registros de diversidad de moluscos holocénicos en la costa de Río de Janeiro, Brasil SARA CHRISTINA PÁDUA, EDSON PEREIRA SILVA & MICHELLE REZENDE DUARTE* Laboratório de Genética Marinha e Evolução, Departamento de Biologia Marinha, Instituto de Biologia, Universidade Federal Fluminense, Outeiro São João Batista, s/n, Centro, Niterói, Rio de Janeiro, CEP: 24001-970, Brazil. *Corresponding author: [email protected] (Received 29 April 2018; Revised 25 September 2018; Accepted 27 November 2018) ABSTRACT: Efficiency of archaeozoological vestiges from shell mounds to recover biodiver- sity patterns were tested using a meso-scale inventory (150 archaeological sites from Rio de Janeiro Coast) of malacological vestiges from sambaquis against an inventory of present times mollusk species recorded for the same area. Statistical analysis were done using Taxonomic Dis- tinctness tests and Trophic Diversity inferences. No statistical significant differences were found between past (sambaquis) and present day inventories of malacofauna. It is concluded that sam- baquis can be valuable proxies of mollusks biodiversity from Late Holocene. Furthermore, it is supported that the incorporation of information from archaeozoological vestiges to biodiversity studies can bring a historical and evolutionary perspective for the field.
