Monitoring of Crustose Coralline Algae Using Low‐Altitude Unmanned Aerial Vehicles in Intertidal Reefs

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
High‐resolution visible‐light imagery from low‐altitude unmanned aerial vehicles, combined with superpixel segmentation and a Random Forest classifier, provides an efficient and scalable framework for mapping and monitoring crustose coralline algae and reef habitats.

Assessment of macrobenthic communities of rocky intertidal zone from Zhejiang offshore islands with AZTI marine biotic index

open access: yesEcological Indicators, 2023
The structure of macrobenthic communities in island intertidal zones serves as an important indicator for assessing the health status of ecosystems. In recent years, the unregulated and extensive development and utilization of island resources in China ...

Microhabitat use by two rocky shore gastropods in an intertidal sandy substrate with rocky fragments [PDF]

open access: yesBrazilian Journal of Biology, 2006
Sandy beaches in some areas of the São Sebastião Channel in southeastern Brazil have unremittingly undergone a variety of impacts, including the deposition of rock fragments in the intertidal region. Consequently, these environments support a rich fauna comprising both sandy beach and rocky shore organisms.

Micronuclei and Other Nuclear Abnormalities in Patella Limpet as Biomarkers of Cytogenotoxicity in Recreational Port Waters

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Over the past decades, the growth in human population and economic activities has led to an increase in maritime traffic. This rise puts additional pressure on marine environments, vessel fuel spills being considered to have a major impact on the ecosystem.

Physiological Ecology of Rocky Intertidal Organisms: A Synergy of Concepts [PDF]

open access: yesIntegrative and Comparative Biology, 2002
The rocky intertidal zone is among the most physically harsh environments on earth. Marine invertebrates and algae living in this habitat are alternatively pounded by waves and exposed to thermal extremes during low tide periods (Denny and Wethey, 2001).

From the individual to the community and beyond: water quality, stress indicators and key species in coastal waters [PDF]

open access: yes, 1994
This review examines water quality and stress indicators at levels of organisation from the individual to the community and beyond by means of three case studies concentrating on rocky shores within the north-east Atlantic.

Rapid Assessment of Intertidal Wetland Sediments [PDF]

open access: yes, 2012
Urbanization of coastal areas poses a severe threat to ecologically valuable intertidal wetlands. This paper presents a pragmatic approach called Rapid Assessment for Intertidal Wetland Sediments (RAITWS) for evaluating the sediment quality of intertidal

Distance sampling: comparing walked transects and road transects for rock ptarmigan densities and population trends

open access: yesWildlife Biology, EarlyView.
We compared population trends for rock ptarmigan Lagopus muta densities (2003‒2019) derived from walked transects and driven road transects in Mosfellsheiði and Slétta in southwest and northeast Iceland, respectively. The walked transects were laid out according to a random rule.
