Impact of tidal dynamics on diel vertical migration of zooplankton in Hudson Bay [PDF]

Ocean Science, 2020
Hudson Bay is a large seasonally ice-covered Canadian inland sea connected to the Arctic Ocean and North Atlantic through Foxe Basin and Hudson Strait. This study investigates zooplankton distribution, dynamics, and factors controlling them during open ...

Upward phosphorus transport by Daphnia diel vertical migration [PDF]

Limnology and Oceanography, 2009
In many lakes, zooplankton show a distinct diel vertical migration (DVM) behavior, especially during periods of stratification. Excretion products of these zooplankton could potentially cause an upward nutrient transport and consequent nutrient enrichment for phytoplankton in the epilimnion.

Recent Advances in Cryogel Applications for Musculoskeleatal Regeneration

Medicinal Research Reviews, EarlyView.
ABSTRACT Hydrogels have been widely used in tissue engineering due to their high‐water content and biocompatibility, yet their densely cross‐linked microstructure inherently limits cell infiltration, mass transport, and mechanical support. Cryogels, formed through partial freezing and crosslinking under subzero conditions, provide unique 3D macroporous

Diel dynamics of zooplankton fecal pellet flux revealed by integrated in situ imaging observations and modeling

Limnology and Oceanography Letters
The contribution of sinking fecal pellets to the biological carbon pump depends on pellet properties, producer abundance, and the depth and timing of pellet production, which can be modulated by diel vertical migration.

Conjugated Polymers Engineered for Flexible/Stretchable Electronics

Journal of Polymer Science, EarlyView.
This review highlights glass transition temperature (Tg) as the central parameter linking molecular structure to device performance in conjugated polymers. By tuning backbone rigidity, side‐chain architecture, and dynamic bonding, Tg governs the balance between π–π stacking–enabled charge transport and mechanical compliance.

Vertical Fine-Scale Distribution of Calanus sinicus in the Yellow Sea Cold Water Mass During the Over-Summering Process

Frontiers in Marine Science, 2021
Calanus sinicus, a temperate copepod with a lethal temperature >27°C, is one of the key species in Chinese coastal marine ecosystems. The C. sinicus population increases in spring and declines in early summer annually due to increasing water ...

Increased phototaxis in the field leads to enhanced diel vertical migration [PDF]

Limnology and Oceanography, 1994
Downward and upward displacement velocity of diel vertical migration in Lake Maarsseveen by the hybrid Daphnia galeata × hyalina, was correlated with the relative change in light intensity at dawn and dusk, indicating a phototactic basis for these migrations. The significance of the regression function increased over a period of 4 yr.

River‐Scale Evaluation of a Floating LED Light Array for Behavioral Guidance of American Eel

River Research and Applications, EarlyView.
ABSTRACT Exploiting the sensory physiology of migratory fishes to guide them away from hazards like hydroelectric turbines is of interest to regulatory agencies and hydropower operators to achieve conservation and management goals. Here we describe a river‐scale experiment where out‐migrating adult American eel (Anguilla rostrata) were tracked ...

Migratory Zooplankton Excreta and Its Influence on Prokaryotic Communities

Frontiers in Marine Science, 2020
Particulate organic matter (POM) (fecal pellets) from zooplankton has been demonstrated to be an important nutrient source for the pelagic prokaryotic community.

Search and Passage Are Decoupled for Migrating Trout Kelts at Multi‐Exit Dam

River Research and Applications, EarlyView.
ABSTRACT Longitudinal and lateral river connectivity have been drastically reduced over time, with hydropower development as a major driver of fragmentation. While fishways are widely implemented to support upstream migration, downstream passage remains a major challenge.
