Analysis of Red Tide Characteristics in Tianjin Coastal Seawater

open access: yesHaiyang Kaifa yu guanli
Through statistical analysis of the red tides that occurred in the coastal waters of Tianjin from 2001—2020, it was found that in recent years, the occurrence of red tide in Tianjin coastal seawater exhibits high-frequency, small-scale characteristics ...

Sympatho‐Excitation in Pulmonary Hypertension: The Potential Role of Pulmonary Arterial Baroreceptors: An Acute Physiologic Intervention Study

open access: yesRespirology, EarlyView.
Pulmonary arterial baroreceptors reflexively stimulate sympathetic nerve activity (SNA) in response to elevated pulmonary artery pressure and distension. In pulmonary hypertension patients, changes in muscle SNA were proportional to changes in pulmonary haemodynamics following nebulised iloprost.

Determinants of Improved Dyspnea and Exercise Tolerance With Nasal High‐Flow O2 Therapy in Fibrotic Interstitial Lung Disease: A Pilot Physiological Study

open access: yesRespirology, EarlyView.
We tested the respective effect of high‐flow and supplemental O2 from nasal high‐flow O2 therapy (NHFO2) on dyspnea and exercise tolerance in fibrotic interstitial lung disease. Supplemental O2 and NHFO2 (but not high‐flow) provided improvements in these outcomes at “iso‐O2 saturation” due to reduced ventilatory requirements.

STATISTICAL ANALYSES WITH METEOROLOGICAL FACTORS, AND APPLICATIONS OF RS AND GIS TECHNIQUES FOR RED TIDE FORMATION IN THE KOREAN COASTAL WATERS

open access: yesGayana, 2004
It was studied on the choice of potential area for red tide occurrence from oceanographic factors. Oceanographic factors of favorable marine environmental conditions for the red tide formation included warm water temperature, low salinity, high suspended

Long‐Term Morphodynamic Responses to Flood Diversion in the Lower Kano River, Japan

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Fluvial morphodynamics—the interaction between water flow, sediment transport, and channel morphology—is a central concern in sustainable river management. However, the long‐term effects of flood diversion remain underexplored. This study investigated the decadal‐scale morphodynamic responses of the lower Kano River in Japan following the ...

Development and Improvement of Habitat Suitability Criteria for Instream Habitat Assessments Conducted in Support of Environmental Flows in Florida

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...

Classification and Spatiotemporal Distribution Characteristics of Coastal Red Tide Disasters in Guangdong Province from 2001 to 2023

open access: yesHaiyang Kaifa yu guanli
The natural breakpoint method was applied to classify and quantify data on area, duration, hazard types and economic losses from 237 red tide events along the Guangdong coast between 2001 and 2023.

Wall‐to‐wall Amazon forest height mapping with Planet NICFI, Aerial LiDAR, and a U‐Net regression model

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Tree canopy height is a key indicator of forest biomass and structure, yet accurate mapping across the Amazon remains challenging. Here, we generated a canopy height map of the Amazon forest at ~4.8 m resolution using Planet NICFI imagery and a deep learning U‐Net model trained with airborne LiDAR data.

Monitoring of Crustose Coralline Algae Using Low‐Altitude Unmanned Aerial Vehicles in Intertidal Reefs

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
High‐resolution visible‐light imagery from low‐altitude unmanned aerial vehicles, combined with superpixel segmentation and a Random Forest classifier, provides an efficient and scalable framework for mapping and monitoring crustose coralline algae and reef habitats.
