Diet and Oral Health of Scythian Populations in Ukraine (700–200 bce): Evidence for Grain Consumption and Food Processing

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT We examined whether Scythian‐era populations living in different ecological zones had distinctive oral health patterns during the Iron Age. Our interdisciplinary approach should clarify whether these populations had different diets or behavioral practices.

Fishing gear for prawn and shrimp used in the Philippines today

, 1980
The report describes the different gears used for collecting penaeids which have been traditionally used in the Philippines. Twenty gears are presently found throughout the Philippines: nine for collecting sugpo fry and 13 for capturing adult prawns ...

Statistical evaluation of nylon chemical recycling through acidolysis

Polymer International, EarlyView.
Sustainable PA6 recycling through acidolysis enabled temperature‐driven depolymerization, modeled by regression analysis. Recycled products successfully replaced up to 30% monomer while preserving PA6 chemical composition or crystalline structure. Abstract This study focuses on the sustainability of plastics reporting the recycling of polyamide (PA ...

Effect of gillnet mesh size on the capture probability and capture patterns in the Asian paddle crab (Charybdis japonica) fishery

Heliyon
In the Asian paddle crab (Charybdis japonica) gillnet fishery in the Yellow Sea, China, the minimum mesh size (MMS) regulation has been of a major importance due to high bycatch rates of undersized crabs. In this study, we evaluated how gillnet mesh size

Actuation Strategies for Underwater Jet‐Propelled Soft Robots

Journal of Field Robotics, EarlyView.
ABSTRACT This review article examines jet‐propulsion mechanisms in underwater soft robotic systems, focusing exclusively on physically fabricated and experimentally validated robots. Covering research published from 2013 to 2025, this study classifies and evaluates jet‐propulsion robots based on their actuation mechanisms.

Assessing the sustainability of artisanal fishing practices in Mediterranean Lagoons: Insights from Manzala Lagoon, Egypt

Egyptian Journal of Aquatic Research
This study investigates the fishing activities in Manzala Lagoon, Egypt—a critical ecosystem facing anthropogenic pressures. Data on fishing gear usage, catch composition, and catch per unit effort (CPUE) were collected from 132 traditional fishing boats

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

River 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 ...

The impact of government subsidies on microplastic pollution control in mariculture: an evolutionary game theory analysis in Qingdao, China

Frontiers in Marine Science
Mariculture constitutes the primary origin of microplastic pollution, necessitating immediate action to address microplastic pollution by focusing on both the supply and demand aspects of fishing gear.

Fishing-gear restrictions and biomass gains for coral reef fishes in marine protected areas

, 2018
Considerable empirical evidence supports recovery of reef fish populations with fishery closures. In countries where full exclusion of people from fishing may be perceived as inequitable, fishing‐gear restrictions on nonselective and destructive gears ...

A Multi‐Method Approach to Assessing Barrier Effectiveness in Preventing the Spread of Invasive Signal Crayfish (Pacifastacus leniusculus)

River Research and Applications, EarlyView.
ABSTRACT Relieving barriers and increasing free flowing rivers is a global imperative to restore habitat connectivity for migratory fish stocks. While reducing river fragmentation will certainly improve biodiversity, the spread of non‐native species throughout a river system may be facilitated as an inadvertent outcome.
