Multipartner Symbiosis across Biological Domains: Looking at the Eukaryotic Associations from a Microbial Perspective

mSystems, 2019
Sponges establish tight associations with both micro- and macroorganisms. However, while studies on sponge microbiomes are numerous, nothing is currently known about the microbiomes of sponge-associated polychaetes and their relationships with those of ...

The Role of Manipulating Photoperiod and Temperature in Oocyte Development of the Polychaete Hediste diversicolor (O.F. Müller, 1976)

Frontiers in Marine Science, 2020
Three different experiments were conducted to examine the oocyte development of the polychaete Hediste diversicolor in response to changing photoperiod and temperature at three different periods of oogenesis.

Evidence for a Role of Extraintestinal Pathogenic Escherichia coli, Enterococcus faecalis and Streptococcus gallolyticus in the Aetiology of Exudative Cloacitis in the Critically Endangered Kākāpō (Strigops habroptilus)

Molecular Ecology, EarlyView.
ABSTRACT The kākāpō is a critically endangered flightless parrot which suffers from exudative cloacitis, a debilitating disease resulting in inflammation of the vent margin or cloaca. Despite this disease emerging over 20 years ago, the cause of exudative cloacitis remains elusive.

Oyster condition index in Crassostrea rhizophorae (Guilding, 1828) from a heavy-metal polluted coastal lagoon

Brazilian Journal of Biology
The condition index (CI) of oysters represents an ecophysiological approach to estimate meat quality and yield in cultured bivalve mollusks. In the present study, the CI of oysters from a heavy-metal polluted bay was analyzed with respect to Zn and Cd ...

Habitat complexity promotes species richness and community stability: a case study in a marine biogenic habitat

Oikos, EarlyView.
Habitat complexity (HC) promotes species richness and abundance. Aquatic environments are faced with intense pressures that threaten the 3D structure of the seafloor, with cascading effects on ecosystem functioning and biodiversity. Maerl or rhodolith beds are marine biogenic habitats created by few species of free‐living non‐geniculate coralline algae

Distribution patterns of polychaete fauna in an Arctic fjord (Hornsund, Spitsbergen)

Polar Biology, 2013
Polychaetes are one of the most important groups of benthic organisms in marine ecosystems. They dominate on the Arctic shelf and play an important role in ecosystem functioning.

Learning in the Polychaete Nereis [PDF]

Nature, 1965
THE rapid withdrawal reflex of the polychaetes Nereis diversicolor, N. pelagica and Platynereis dumerilii habituates rapidly to sudden stimuli, such as changes in illumination or mechanical stimuli, but if a foreign stimulus is interpolated in a series of stimulus presentations it is usually followed by greater reactivity to the original stimulus ...

Settlement and tidal zonation patterns of closely related oysters within the genus Saccostrea in a subtropical Australian estuary—implications for restoration

Restoration Ecology, EarlyView.
Oyster reefs are considered functionally extinct in many global regions, and restoration efforts are accelerating. Currently, restoration on Australia's eastern coast is focused on the Sydney rock oyster (Saccostrea glomerata); however, multiple species of Saccostrea are found across this region.

Pulsatile Ventilation Flow in Polychaete Alitta succinea Burrows

Journal of Marine Science and Engineering
In aquatic sediments, active ventilation of burrows is an important component of sediment metabolism, transporting solutes across the sediment–water interface.

Aquatic food webs in restored marshes: a stable‐isotope approach in the Gironde estuary (SW France)

Restoration Ecology, EarlyView.
Intertidal marshes are important habitats for nekton. However, historical draining and dyking hampered European coastal wetlands. Marsh restoration is therefore critical not only to improve their capacity to protect coastal lines but also to rehabilitate their ecological functionalities. The benefits of intertidal marsh restoration for nekton community
