Trends in marine species distribution models: a review of methodological advances and future challenges

open access: yesEcography, EarlyView.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Unveiling CLC as a Central Regulator of Allergic Rhinitis via the CLC‐CCL26/POSTN Axis: An Integrated Bioinformatics and Experimental Study

open access: yesFlavour and Fragrance Journal, EarlyView.
We unveil that CLC orchestrates the dual role of eosinophil recruitment via CCL26 and tissue remodelling via POSTN in allergic rhinitis, identifying it as a potential therapeutic target. ABSTRACT Allergic rhinitis (AR) is a chronic airway inflammation driven by a type 2 immune response, yet the molecular mechanisms underlying its persistence and tissue

A Fuzzy Framework for Realized Volatility Prediction: Empirical Evidence From Equity Markets

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT This study introduces a realized volatility fuzzy time series (RV‐FTS) model that applies a fuzzy c‐means clustering algorithm to estimate time‐varying c$$ c $$ latent volatility states and their corresponding membership degrees. These memberships are used to construct a fuzzified volatility estimate as a weighted average of cluster centroids.

Application Research of Microstructured Flexible Sensors in Rehabilitative Wearable Sensing

open access: yesiNew Medicine, EarlyView.
ABSTRACT Flexible sensors enable the continuous, real‐time monitoring of the physiological and movement signals of patients, providing data support for precise rehabilitation strategies and playing a crucial role in rehabilitation medicine. However, traditional rigid sensors are often incompatible with dynamic body contours due to their high material ...

Population size and survivorship for juvenile lemon sharks (Negaprion brevirostris) on their nursery grounds at a marine protected area in Brazil

open access: yesNeotropical Ichthyology
Sharks face a number of obstacles for surviving their first several years of life and many species occupy nursery areas. Although estimates of survival, particularly for young age classes, are essential for assessing, monitoring and effectively managing ...

Great hammerhead sharks swim on their side to reduce transport costs

open access: yesNature Communications, 2016
Sharks’ dorsal fins are thought to assist propulsion and turns while pectoral fins are thought to oppose sharks’ negative buoyancy. Here, Payne and colleagues show that hammerhead sharks use an exaggerated dorsal fin to generate lift by swimming on their

Born to be free? Assessing the viability of releasing captive-bred wobbegongs to restock depleted populations

open access: yesFrontiers in Marine Science, 2015
Large predatory fishes, such as sharks, play an important functional role within marine ecosystems. Restocking of depleted populations has been extensively studied for commercially or recreationally important teleost fish species; however, it has, to the
