Physiological Response of Thallasia hemprichii on Antrophogenic Pressure In Pari Island, Seribu Islands, DKI Jakarta

open access: yesIlmu Kelautan, 2017
Seagrass ecosystem is one of tropical marine ecosystem and have important function. The function of ecosystem like a feeding and nursery ground for marine biota. Antrophogenic pressure is one of threat for seagrass ecosystem sustainability. This research

300 Years of Degradation in Wales Estuaries and Coasts

open access: yesNatural 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.

Geographic Patterns of Head Morphology in Syngnathus typhle Across Marine Regions

open access: yesIntegrative 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.

Habitat-mediated facilitation and counteracting ecosystem engineering interactively influence ecosystem responses to disturbance [PDF]

open access: yes, 2011
Recovery of an ecosystem following disturbance can be severely hampered or even shift altogether when a point disturbance exceeds a certain spatial threshold. Such scale-dependent dynamics may be caused by preemptive competition, but may also result from

A Comprehensive Repository of Morphological, Life‐History, Ecological, and Environmental Data for Sirenians and Marine Carnivorans Worldwide

open access: yesIntegrative Zoology, EarlyView.
We constructed a standardized data repository for all 46 species, integrating 56 variables across morphological and physiological, life‐history, ecological, biogeographical, environmental, and conservation dimensions. Additionally, we collected data on body size, coloration, distributional range, and extinction risk for all 22 subspecies.

Rocking the Boat: Damage to Eelgrass by Swinging Boat Moorings

open access: yesFrontiers in Plant Science, 2017
Seagrass meadows commonly reside in shallow sheltered embayments typical of the locations that provide an attractive option for mooring boats. Given the potential for boat moorings to result in disturbance to the seabed due to repeated physical impact ...

Effects of Fine Sediment on Seagrass Meadows: A Case Study of Zostera muelleri in Pāuatahanui Inlet, New Zealand

open access: yesJournal of Marine Science and Engineering, 2020
Seagrass meadows are vulnerable to fine sediment (mud) pollution, with impacts usually attributed to reduction in submerged light. Here we tested two non-exclusive hypotheses, that mud particles (

A validated 3D point‐cloud analysis workflow for the creation of seagrass canopy height models

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Seagrasses support highly productive ecosystems in both temperate and tropical waters and provide essential ecosystem services. Despite their importance, the vertical structure of seagrasses (i.e. the canopy) remains poorly characterised at the microscale, even though it is a strong predictor of ecological processes that influence both ...

Factors influencing seagrass recovery in Feather Sound, Tampa Bay, Florida [PDF]

open access: yes, 2004
This document is a summary of the findings and recommendations of the Feather Sound Seagrass Recovery Workgroup. In response to nutrient load reductions and resulting clearer water, seagrasses have expanded significantly in many areas of Tampa Bay since ...

Occurrence of the alien seagrass Halophila stipulacea in Martinique (French West Indies) [PDF]

open access: yes, 2013
The occurrence of the tropical seagrass Halophila stipulacea (Hydrocharitaceae) is recorded for the first time on the Caribbean coast of Martinique (French West Indies, Caribbean Sea).
