300 Years of Degradation in Wales Estuaries and Coasts

Natural Resources Forum, EarlyView.
ABSTRACT The world's oceans are in a severe state of degradation, yet our understanding of that degradation is often based on changes observed only in the past 20–50 years. This narrow view leads to marine conservation efforts that aim to preserve already degraded ecosystems, shaped by shifted ecological baselines.

Comparison of water velocity profiles through morphologically dissimilar seagrasses measured with a simple and inexpensive current meter [PDF]

, 2002
The influence of seagrass morphology on water flow was studied by measuring water velocity profiles through natural seagrass meadows. An array of eight solid-state electronic current meters was used to obtain profiles through meadows of Amphibolis ...

Geographic Patterns of Head Morphology in Syngnathus typhle Across Marine Regions

Integrative Zoology, EarlyView.
Morphometric analysis of Syngnathus typhle head shape shows distinct geographic patterns across Baltic, North, Atlantic, and Mediterranean marine regions, driven by variation in snout length, head depth, and eye position. Findings provide a non‐invasive baseline for conservation monitoring.

Testing for thresholds of ecosystem collapse in seagrass meadows

Conservation Biology, 2017
Abstract Although the public desire for healthy environments is clear‐cut, the science and management of ecosystem health has not been as simple. Ecological systems can be dynamic and can shift abruptly from one ecosystem state to another.

UNIQAT: An open‐source toolkit for reproducible image quality assessment in marine surveys

Methods in Ecology and Evolution, EarlyView.
Abstract Modern marine surveys generate tens of thousands of underwater images per expedition, yet many are unusable due to image quality deterioration. Manual quality screening is labour‐intensive, subjective and inconsistent across observers and teams, hindering reproducible science, creating large backlogs of unprocessed imagery, and limiting real ...

The status of Indonesia’s seagrass meadows

, 2018
Indonesia stores 2% of the world’s blue carbon in its seagrass meadows, which are under threat from human activities like coastal development. Without a long-term, large-scale monitoring effort, the continual decline and hopeful recovery of this vital ecosystem will be very difficult to track.

Mapping of Posidonia oceanica (L.) Delile Meadows Using Geographic Information Systems: A case study in Ufakdere - Kaş (Mediterranean Sea)

International Journal of Environment and Geoinformatics, 2016
Posidonia oceanica (Linnaeus) Delile 1813 is an endemic and the most widespread seagrass species of the Mediterranean Sea. Seagrass meadows are one of the most productive ecosystems on Earth, providing habitat to numerous organisms.

The Optimism Ignited by Nature‐Based Solutions: Mobilizing Public Support and Policy Champions in a “First‐Ever” Oyster Reef Restoration Project

Culture, Agriculture, Food and Environment, EarlyView.
ABSTRACT In recent years, a major push to restore oyster reefs has helped to revive the marine environments that were depleted in South Australia. Categorized as “Nature‐based Solutions” (NbS) that foster the return of biodiversity, these efforts have led to pockets of environmental optimism while countering an otherwise gloomy marine health forecast ...

Evolutionary legacies structure the geography of seagrass traits across the world's oceans

New Phytologist, EarlyView.
Summary Traits modulate species' ability to track shifts in climate, yet the extent to which traits have been shaped by the contemporary environment and/or historical processes remains poorly understood. Here, we fill this gap for the world's seagrasses, habitat‐forming species that provide critical ecosystem services.
