The biology and ecology of benthic foraminifera inhabiting intertidal mudflats [PDF]

open access: yes, 2015
Benthic foraminifera inhabiting the mudflats of the Eden Estuary, NE Scotland, exhibited a single annual peak in abundance at both high (270 individuals 10 cm⁻²) and low shore (210 individuals 10 cm⁻²) intertidal sampling stations during June 2000 ...

The mechanisms of intertidal fish coexistence: a model [PDF]

open access: yes, 2014
Research into the ecology of intertidal fishes of the U.K. appears to be lacking, reportedly due to the mobility and cryptic nature of the more common species. However, some intertidal fishes contribute to the diets of commercially important species such as cod ( Gadus morhua ), haddock (

Comparison of 3D structural metrics on oyster reefs using unoccupied aircraft photogrammetry and terrestrial LiDAR across a tidal elevation gradient

open access: yesRemote Sensing in Ecology and Conservation, 2023
Physical structures generated from ecosystem engineers can have a cascade of impacts on the ecological community and the surrounding landscape. The Eastern oyster Crassostrea virginica can form extensive intertidal reefs, whose three‐dimensional ...

Semilunar follicular cycle of an intertidal fish: the Fundulus model [PDF]

open access: yesBiology of Reproduction, 1996
In their habitat, Fundulus heteroclitus (Cyprinodontidae) spawn against a variety of specific substrates that become available only at spring tides; they thus exhibit a semilunar reproductive cyclicity. In the laboratory at 28 +/- 0.6 degrees C and 14L:10D, this cyclicity is free-running and can be observed by means of daily egg collection and frequent

Avian determinants of rocky intertidal community structure in South Africa [PDF]

open access: yes, 1987
Includes bibliographies.Rocky islands in Saldanha Bay, southwestern Cape, South Africa, support aggregations of seabirds. Guano produced by the seabirds washed off the islands into intertidal and nearshore waters,where it provides a source of inorganic ...

Traditional usages of ichthyotoxic plant Barringtonia asiatica (L.) Kurz. by the Nicobari tribes

open access: yesJournal of Marine and Island Cultures, 2015
The Barringtonia asiatica is a medium size tree commonly found in Car Nicobar Island known for its ichthyotoxic property. It grows on sandy and rocky shore areas and has lantern shaped seeds, locally called Kinyav used during the calm season in shallow ...

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

open access: yesLethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Habitat creation and biodiversity maintenance in mangrove forests: teredinid bivalves as ecosystem engineers [PDF]

open access: yesPeerJ, 2014
Substantial amounts of dead wood in the intertidal zone of mature mangrove forests are tunnelled by teredinid bivalves. When the tunnels are exposed, animals are able to use tunnels as refuges.

Primary ecological succession of marine communities on the Tajogaite lava flows (La Palma, Canary Islands), fishes colonize faster than macroinvertebrates and algae

open access: yesFrontiers in Marine Science
We studied the primary succession of benthic communities in the lava flows of the Tajogaite volcano at 2, 4.5, and 7 months after the eruption ended. The lava from the Tajogaite created several lava flows and sterile rocky reefs that were monitored in ...
