Multiple Driver Impacts on Rocky Intertidal Systems: The Need for an Integrated Approach

open access: yesFrontiers in Marine Science, 2021
Most intertidal rocky systems are exposed to severe tidal, diurnal, and seasonal changes in environmental parameters. In addition, they show extreme vulnerability to anthropogenic impacts.

Further Loss of Intertidal Mussel Stands on the Nova Scotia Coast (Canada) after the Passage of Cyclone Lee

open access: yesDiversity, 2023
Intertidal mussel stands are common on temperate rocky seashores and host many small invertebrates, so they are important biodiversity reservoirs. Their integrity, however, is being increasingly affected by environmental extremes. An unusual cold snap in

High-Resolution Drone Images Show That the Distribution of Mussels Depends on Microhabitat Features of Intertidal Rocky Shores

open access: yesRemote Sensing, 2022
In this study, we used orthomosaics and a digital surface model (DSM) generated from drone surveys to (1) characterize the distribution of mussel (Mytilus galloprovincialis) aggregations at high resolution (centimeters), and (2) evaluate the role of ...

Application of a Simple, Low-Cost, Low-Tech Method to Monitor Intertidal Rocky Shore Assemblages on a Broad Geographic Scale

open access: yesFrontiers in Marine Science, 2021
Identifying susceptible regions where biodiversity changes occur at fast rates is essential in order to protect and ameliorate affected areas. Large-scale coastal monitoring programs that focus on long-term variability are scarce, yet the Marine ...

Marine invertebrate and seaweed biodiversity of continental coastal Ecuador [PDF]

open access: yesBiodiversity Data Journal, 2020
This study summarises the diversity of living macroinvertebrates and seaweeds from the intertidal and subtidal rocky shores along Ecuadorian continental coast. Benthic macroinvertebrate communities and seaweeds were quantified over quadrants (50 × 50 cm)

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)

Shell-size variation of Notoacmea biradiata (Archaeogastropoda: Acmaeidae) as a response to gastropod density and height in shore in the Colombian Pacific coast

open access: yesCiencias Marinas, 2002
Notoacmea biradiata (Reeve, 1855) is an abundant intertidal limpet on the rocky shore of the Colombian Pacific coast. This paper reports a field factorial experiment on shell-size variation of N.

Kite aerial photography for low-cost, ultra-high spatial resolution multi-spectral mapping of intertidal landscapes. [PDF]

open access: yesPLoS ONE, 2013
Intertidal ecosystems have primarily been studied using field-based sampling; remote sensing offers the ability to collect data over large areas in a snapshot of time that could complement field-based sampling methods by extrapolating them into the wider
