Early life history of the Korean seahorse, Hippocampus haema: Evidence for direct settlement and ontogenetic shifts in snout morphology

Journal of Fish Biology, EarlyView.
Abstract Early life‐history traits of seahorses are closely linked to juvenile survival, dispersal potential and the onset of substrate attachment; however, detailed stage‐resolved descriptions remain limited for many Hippocampus species. This study examined reproductive behaviour and early ontogenetic development of the Korean seahorse, Hippocampus ...

Dive surveys and eDNA detect contrasting macroalgal community composition in Nova Scotia, Canada

Journal of Phycology, EarlyView.
Abstract Morphological identification of macroalgae can be time‐consuming and species may be difficult to observe, collect, or identify, preventing detailed study on the distribution and ecology of many species. The use of eDNA in species surveillance and biodiversity assessments has gained considerable traction in studying macroalgae, as it provides ...

A blessing or a curse: Responses of eelgrass (Zostera marina) seedlings to combined stressors of nutrients, hypoxia and sulfide

Ecological Indicators, 2023
Eelgass (Zostera marina) beds have many functions; however, eelgrass populations have declined in recent decades. Thus, it is important to recover eelgrass populations.

Global meta‐analysis highlights recovery of animal functional diversity in restored coastal ecosystems

Restoration Ecology, EarlyView.
Abstract Introduction Coastal ecosystems have experienced widespread global degradation, prompting substantial investment in restoration. While structural recovery is well documented, whether restoration reestablishes the functional diversity (FD) of animal communities and how recovery unfolds through time remains poorly resolved.

Two eDNA Assays to Detect the Sympatric Seahorses Hippocampus hippocampus and Hippocampus guttulatus During Their Northward Range Shifts

Environmental DNA, Volume 8, Issue 5, September‐October 2026.
Small and well camouflaged fish are difficult to monitor, but they do release DNA into the water (1). These assays allow for targeted monitoring of two European seahorses of conservation concern, using two primers and probe pairs with high specificity (2) and proven detections from the field (3).

Bed‐level tools for monitoring erosion and accretion patterns: Flume validation and field testing

Limnology and Oceanography: Methods, Volume 24, Issue 9, September 2026.
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 ...

Blue Carbon Storage in a Northern Temperate Estuary Subject to Habitat Loss and Chronic Habitat Disturbance: Cowichan Estuary, British Columbia, Canada

Frontiers in Marine Science, 2022
Vegetated coastal ecosystems can contribute greatly to long-term carbon sequestration and greenhouse gas emission mitigation, providing a strong argument for their protection and restoration.

Dune grass production is positively associated with marine nutrient subsidies on US Central Atlantic coast foredunes

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Resource subsidies, or the flow of energy across ecosystem boundaries, can influence community structure and function and act as important nutrient sources to less productive ecosystems, particularly in marine and coastal zones. Coastal dunes, connected to the nearshore through sandy beaches, likely depend on the delivery of marine subsidies ...

Ecological Restoration of a Cultivated Wetland to Enhance Nitrogen Retention in a Rapidly Developing Watershed

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract For much of the coastal United States, water quality continues to worsen due to excess nitrogen (N) from agricultural production and urban development. Restoration of freshwater wetlands, especially those connected to streams (i.e., fluvial wetlands), is a promising management option for curtailing watershed inputs of N to coastal embayments ...

Spatial and Temporal Variation of C, N, and S Stable Isotopes and Seagrass Coverage Related to Eutrophication Stress in Zostera marina

Coasts
Zostera marina is an ecologically valuable species that has been declining due to anthropogenic environmental stressors. In this study, spatial and temporal indicators of eelgrass stress, such as coverage and biomass, were compared with the isotopic ...
