Polar‐low track prediction using machine‐learning methods

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Machine‐learning models are developed to produce reliable and efficient forecasts of polar‐low (PL) trajectories 12 hours ahead. A temporal model (RLSTM) benefiting from the rolling‐forecast strategy, improves overall prediction accuracy and is suitable for quick experimentation, while a spatiotemporal model (PL‐UNet), incorporating both historical and

An environmental assessment of the John Pennekamp Coral Reef State Park and the Key Largo Coral Reef Marine Sanctuary (Unpublished 1983 Report) [PDF]

open access: yes, 2002
The Pennekamp Coral Reef State Park was established in 1960 and the Key Largo National Marine Sanctuary in 1975. Field studies, funded by NOAA, were conducted in 1980 - 1981 to determine the state of the coral reefs and surrounding areas in relation to ...

Hydropower Operations Reduce Alluvial Nesting Habitat and Alter Riverine Turtle Population Demographics

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Hydropower management has altered discharge regimes of large rivers worldwide, reducing sediment mobilization and early‐seral conditions essential for many riverine species. Spiny softshell turtles (Apalone spinifera) rely on alluvial habitats for nesting and may serve as sentinel species to assess the effects of regulated flow regimes and ...

Population Dynamics of Northern Pearl Dace Margariscus nachtriebi in Anthropogenically Altered Headwater Streams of the Nebraska Sandhills Ecoregion

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Empirical evidence of population demographic responses to environmental perturbations is a major knowledge gap for aquatic vertebrate populations. Extensive habitat alteration including channelization of headwater streams influences the habitat template on which small‐bodied fish are dependent to carry out distinct life stages and maintain or ...

海龟鳍状肢标记技术的全球性环境影响评估

open access: yesWildlife Letters
Although sea turtle flipper tagging is a tenet field technique generating irreplaceable scientific data worldwide since the inception of sea turtle conservation in 1920s along the Great Barrier Reef, the procedure was reported to trigger outbreaks of sea

Programmed unmanned aerial vehicles show great potential for monitoring marine megafauna in specific areas of interest

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Targeted conservation measures are contingent on robust knowledge of spatio‐temporal animal distribution in areas of interest. We explore unmanned aerial vehicle (UAV) transect monitoring as a novel method for standardized digital aerial surveys of marine megafauna by investigating the fine‐resolution spatio‐temporal distribution of harbour porpoises ...

Tourism as a Catalyst for Blue Carbon Restoration and Conservation: Pathways, Gaps, and Opportunities

open access: yesSustainable Development, EarlyView.
ABSTRACT Tourism is a major driver of coastal economies worldwide, yet it is also a growing source of pressure on blue carbon ecosystems (BCEs) such as mangroves, seagrasses, and salt marshes. Nowadays, tourism‐led conservation/restoration is increasingly promoted under the banner of regenerative tourism, but how these projects are motivated ...

Systematic Learning and Pedagogy Through a Modular, Progressive‐Based Simulation Modeling Framework for Complex Systems

open access: yesSystems Engineering, EarlyView.
ABSTRACT Smart Transportation Systems (SmTS) will exceed complex systems with their classification as complex, sociotechnical, and AI‐based systems. Possessing a toolkit that helps systemically understand, analyze, and assess these systems will be advantageous in the early stages of the systems engineering (SE) lifecycle, and Agent Based Models (ABMs ...

Exploring the Impact of Polystyrene Microplastic Beads on Male Gonads of the Marine Mussel, Mytilus galloprovincialis

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Plastic, with its remarkable versatility and numerous applications, has greatly benefited humanity. However, its extreme resistance to natural degradation means it persists in the environment for long periods, causing global environmental problems.

Assessing the Health Impacts of Contaminants on Green Turtles (Chelonia mydas) Along the Southern Coast of Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Chemical pollutants pose a significant threat to marine ecosystems. Among these contaminants are trace elements and polycyclic aromatic hydrocarbons (PAH). Green turtles can be employed to evaluate the oceans' health due to their coastal habitats and exposure to multiple threats.
