Seasonal Biodiversity of Fishery Resources by Set Net in the Intertidal Zone to the Southwest of the Yellow River Estuary

open access: yesProgress in Fishery Sciences, 2023
The Yellow River estuary is one of the three largest estuaries along the coastal waters of China, along with the Yangtze and Pearl River estuaries. Its adjacent seawaters are rich in biological resources, with abundant fish habitat, spawning grounds, and

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

Change in fish functional diversity and assembly rules in the course of tidal marsh restoration.

open access: yesPLoS ONE, 2018
Functional trait theory provides a mechanistic framework to understand change in community composition and community assembly through time and space. Despite this, trait-based approaches have seldom been used in ecological restoration.

Spatial and temporal patterns of benthic invertebrates in the Tagus estuary, Portugal: comparison between subtidal and an intertidal mudflat

open access: yesScientia Marina, 2009
Intertidal mudflats are a dominant feature in many estuarine systems and may be a significant component of the feeding grounds available for many fish and bird species.

Intertidal rockpool icthyofauna of El Pital, La Libertad, El Salvador [PDF]

open access: yesCheck List, 2012
The composition of the rockpool fish community of El Pital was described. A total of 29 rockpools with volumes ranging from 0.12 to 0.83 m3 were sampled from March to September 2009 using dip nets and clove oil anesthetic solution.

Do Large Carnivores and Mesocarnivores Have Redundant Impacts on Intertidal Prey?

open access: yesPLoS ONE, 2017
The presence of large carnivores can affect lower trophic levels by suppressing mesocarnivores and reducing their impacts on prey. The mesopredator release hypothesis therefore predicts prey abundance will be higher where large carnivores are present ...

Long-term changes in seagrass and benthos at Banc d’Arguin, Mauritania, the premier intertidal system along the East Atlantic Flyway

open access: yesGlobal Ecology and Conservation, 2020
The benthic communities of soft-sediment intertidal ecosystems trophically underpin the migration of birds and fish. Within the East Atlantic Flyway, along the coast of West-Africa, the intertidal mudflats of Banc d’Arguin, Mauritania, host over 2 ...

Niche-Relationships Within and Among Intertidal Reef Fish Species

open access: yesFrontiers in Marine Science, 2021
Niche-related processes (e.g., density or niche-breadth compensation and competition) are fundamental to a broad understanding of community ecology and ecosystem functioning.

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)

Patterns of recruitment of the sand smelt (Atherina presbyter) on rocky intertidal habitats

open access: yesFrontiers in Marine Science, 2015
The Portuguese coast is located in a biogeographical transition zone between temperate and subtropical waters making it especially vulnerable to the effects of climate change.
