Table 3) Growth rates of the juvenile polychaete Scolelepis squamata obtained from ice cores under varying conditions

open access: greenPolar Biology, 2012
In spring, Arctic coastal fast ice is inhabited by high densities of sea ice algae and, among other fauna, juveniles of benthic polychaetes. This paper investigates the hypothesis that growth rates of juveniles of the common sympagic polychaete, Scolelepis squamata (Polychaeta: Spionidae), are significantly faster at sea ice algal bloom concentrations ...

Spawning and reproductive morphology of Scolelepis squamata (Spionidae: Polychaeta)

open access: closedCanadian Journal of Zoology, 1970
The adults of three populations of the spionid polychaete Scolelepis squamata were studied throughout a year in Barbados. From quantitative estimates of gametes and numbers of breeding animals, four statistically reliable outbursts of spawning were determined, each about 2 months apart, followed by a cessation of breeding activity from November till ...

The effect of the dominant polychaete Scolelepis squamata on nematode colonisation in sandy beach sediments: An experimental approach

open access: closedEstuarine, Coastal and Shelf Science, 2011
The effect of an abundant sandy beach polychaete, Scolelepis squamata, on the colonisation of defaunated sediments by marine nematodes indicates that sandy beach fauna can be partially controlled by biological interactions within and across size groups.

Variability of macrofauna distribution along a dissipative log-spiral sandy beach in Rio de Janeiro, Southeastern Brazil

open access: yesScientia Marina, 2017
Log-spiral beaches display defined physical gradients alongshore. However, the majority of studies focus on the variability of a single population of macrofauna species.

Partial revision of Scolelepis (Polychaeta: Spionidae) from the Grand Caribbean Region, with the description of two new species and a key to species recorded in the area [PDF]

open access: yes, 2006
Resumen en inglés: "Five Scolelepis species from the Gulf of Mexico and Western Atlantic Ocean are reported and certain species previously synonymized with Scolelepis (S.) squamata are revised. Four species are reinstated: S. (S.) goodbodyi (Jones, 1962),

Spatial distribution of annelids in the intertidal zone in Sao Sebastiao Channel, Brazil

open access: yesScientia Marina, 2001
We studied the spatial distribution of annelids in the intertidal zone of two beaches (Engenho d´Água and São Francisco) in São Sebastião Channel, southeastern Brazil, from August 1995 through July 1996. This region is commonly affected by oil spills and

Estimates of losses and recovery of ecosystem services for oiled beaches lack clarity and ecological realism

open access: yesEcosphere, Volume 12, Issue 9, September 2021., 2021
Abstract Assessing environmental injury requires accurate, timely information of damage responses and realistic translation of that information into estimates of services lost to the public. The accuracy of both steps improves with the extent of ecological understanding of the impacted habitat; more accurate assessments produce more effective ...

Biodiversity and distribution of macroinfauna assemblages on sandy beaches along the Gulf of Cadiz (SW Spain) [PDF]

open access: yes, 2015
In the current study, the macroinfauna communities inhabiting 12 sandy beaches along the Spanish coast of the Gulf of Cadiz were describe in order to characterize their unexplored biodiversity, their zonation patterns and their environmental features.

Effects of waste waters on benthic macrofauna of sandy beaches in Todos Santos Bay

open access: yesCiencias Marinas, 1992
The seasonal study of the benthic macrofauna in Todos Santos Bay shows the effects of waste waters on the benthic communities of the intertidal zone. The analysis of the data separates the fauna into two main associations: one made up of the populations

Assessing the impact of beach nourishment on the intertidal food web through the development of a mechanistic-envelope model [PDF]

open access: yes, 2014
1. Beach nourishment, the placement of sand onto a sediment-starved stretch of coast, is widely applied as a soft coastal protection measure because of its reduced ecological impact relative to hard coastal protection.
