Bed‐level tools for monitoring erosion and accretion patterns: Flume validation and field testing
Limnology and Oceanography: Methods, EarlyView.Abstract Monitoring short‐term changes in surface sediment elevation is fundamental to understanding erosion, transport, and deposition dynamics in shallow coastal environments. However, commonly used field approaches, such as horizontal markers, sediment erosion tables, subsurface sediment plates, or erosion pins, are not always cross‐validated under ...

Lethaia, 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)

DiversityIn February 2023, a severe cold snap took place in Atlantic Canada and was followed by the mass loss of mussels at mid-to-high intertidal elevations on the southeastern Nova Scotia coast.

Top‐down pressure on a coastal ecosystem by harbor seals
Ecosphere, 2019 Historic hunting has led to severe reductions of many marine mammal species across the globe. After hunting ceased, some populations have recovered to pre‐exploitation levels and may have regained their prominent position as top predator in marine ...

Seagrass species diversity in Tanzania based on morphological and molecular data
Nordic Journal of Botany, EarlyView.Seagrass diversity along the Tanzanian coast has been documented mainly through morphology, with limited molecular reference data available for Tanzania and the wider Western Indian Ocean. This study combined morphological identification with nuclear ribosomal internal transcribed spacer (ITS) and plastid ribulose‐1,5‐bisphosphate carboxylase/oxygenase

Remote Sensing, 2017 The development of satellite-derived datasets has greatly facilitated large-scale ecological studies, as in situ observations are spatially sparse and expensive undertakings.

Oikos, EarlyView.Ecosystem engineers are crucial to the development of coastal ecosystem communities and functions. However, a better understanding of how environmental stressors affect ecosystem engineering and thereby influence communities and ecosystem dynamics is needed. We conducted an in situ experiment in a blue mussel Mytilus spp.

, 2019 This exegesis situates my work in the intertidal zone. In Australia the intertidal zone is a site of historic, cultural, and ecological significance. It is my argument that thinking intertidally attunes us to concepts of inbetweenness and interconnection.

Big Bird: A global dataset of birds in drone imagery annotated to species level
Remote Sensing in Ecology and Conservation, EarlyView.Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds

Climate Change and Intertidal Wetlands [PDF]
Biology, 2013 Intertidal wetlands are recognised for the provision of a range of valued ecosystem services. The two major categories of intertidal wetlands discussed in this contribution are saltmarshes and mangrove forests. Intertidal wetlands are under threat from a range of anthropogenic causes, some site-specific, others acting globally.
