Luminescence dating of coastal deposits from the Chanthaburi Plain, Thailand

Boreas, EarlyView.
The ongoing global sea‐level rise urges us to better understand the dynamics of coastal processes for predicting future changes. Sedimentary deposits reflect past coastal environments but require precise chronological data to place evidence into a temporal context.

Can you really change your stripes? Stable wing ornamentation suggests limited condition‐dependent signalling in female common eiders

Ibis, EarlyView.
Variation in the expression of white ornaments, such as flank spots or wing stripes, has previously been related to indices of individual quality in birds. We measured the white wing stripes of colour‐banded female common eiders Somateria mollissima in three islands in Iceland from 2014 to 2023, to determine whether the expression of these ornaments is

Mollusks: how are they arranged in the rocky intertidal zone? [PDF]

Iheringia. Série Zoologia, 2013
Mollusks occupy different kinds of environments, including the intertidal zone. The present study investigated the spatial distribution of mollusks on beach rocks of the intertidal zone of Pacheco Beach in the state of Ceará, Brazil. Sampling occurred from August 2006 to September 2007.

Hidden partnerships in the dark: Cold‐water coral–fish associations in Fiordland, New Zealand

Journal of Fish Biology, EarlyView.
Abstract The ichthyofauna of the Fiordland ecosystems of southern Aotearoa New Zealand was documented during four remotely operating vehicle (ROV) dives between 100 and 350 m depth. A total of 26 fish species were documented within two fiord basins.

Historical case study of a transfer experiment that demonstrated the importance of the estuarine ecosystem for the survival of Chinook salmon (Oncorhynchus tshawytscha) at the Campbell River estuary, British Columbia, Canada

Journal of Fish Biology, EarlyView.
Abstract Estuary dependence to the survival of Chinook salmon was investigated at the Campbell River estuary, British Columbia, Canada. Replicate batches of marked smolts were transferred from a hatchery and released in 1983, 1984 and 1985 at four ecosystems, two that ensured estuarine experience (river, estuary) and two seawards of the estuary ...

Short‐term performance responses of an intertidal fish to sedimentation and warming

Journal of Fish Biology, EarlyView.
Abstract Climate change is altering coastal ecosystems by causing environmental fluctuations, such as increases in temperature and turbidity, which pose major implications for fish physiology and behaviour. Increases in temperature affect fish food intake, swimming capacity and oxygen delivery, while increases in turbidity can impair or enhance prey ...

Holdfast adhesion in the kelp Alaria marginata: Cell wall polysaccharides and phenolics

Journal of Phycology, EarlyView.
Abstract Adhesion is a critical process in the survival of seaweeds, especially in wave‐swept environments. Kelp (Laminariales) sporophytes secrete adhesives from specialized rhizoid cells to anchor themselves to the substrate and withstand immense forces applied by waves.

Introducing three species of Echinoids (order Echinoidea) in southern intertidal zone of Qeshm Island, the Persian Gulf

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2011
A one-year study (May 2007-April 2008) was undertaken to identify the echinoid species of intertidal sandy and rocky shores of the Qeshm Island. An intertidal sandy location and a rocky shore were surveyed in southern coasts of Qeshm Island, in ...

Trophic ecology of two co-existing Sub-Antarctic limpets of the genus Nacella: spatio-temporal variation in food availability and diet composition of Nacella magellanica and N. deaurata

ZooKeys, 2018
Interactions between algae and herbivores can be affected by various factors, such as seasonality and habitat structure. Among herbivores inhabiting marine systems, species of the order Patellogastropoda are considered key organisms in many rocky coasts ...
