Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion

Advanced Robotics Research, EarlyView.
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Ecosystem‐Centered Robot Design: Toward Ecoresorbable Sustainability Robots (ESRs)

Advanced Science, EarlyView.
Robots exploring natural ecosystems can support monitoring and conservation, but must adopt ecosystem‐centered design to avoid pollution, waste, and damage. This review proposes guidelines for co‐designing ecoresorbable sustainability robots (ESRs), uniting materials, robotics, and ecological contexts in a single framework.

Assessment of fish populations and habitat on Oculina Bank, a deep-sea coral marine protected area off eastern Florida [PDF]

, 2009
A portion of the Oculina Bank located off eastern Florida is a marine protected area (MPA) preserved for its dense populations of the ivory tree coral (Oculina varicosa), which provides important habitat for fish.

Intertidal Warfare: Synergistic Allelopathy Mediates Spatial Competition between Two Marine Calcareous‐Shelled Sessile Organisms

Advanced Science, EarlyView.
This study reveals a hidden chemical weapon among calcareous‐shelled sessile organisms in the intertidal zone: the barnacle Balanus albicostatus releases a synergistic blend of palmitic acid and 1‐palmitoyl‐sn‐glycero‐3‐phosphocholine as the allelochemical with the inhibitory activity against attachment of the mussel Vignadula atrata, which may mediate

Reefscape proxies for the conservation of Caribbean coral reef biodiversity

Ciencias Marinas, 2010
The explanatory value of four hypotheses for geographic variation in total species richness and species richness was evaluated per family in coral and fish communities in the North Sector of the Mesoamerican Barrier Reef System (NS-MBRS).

Reflexive thematic analysis and men's embodiment following injury or illness: A worked example

Anatomical Sciences Education, EarlyView.
Abstract Reflexive thematic analysis (reflexive TA) originated within psychology and the social sciences and has become an increasingly popular qualitative analytic method across a range of disciplines. In this article, we offer a brief methodological guide for researchers hoping to use the method, suitable for beginners through to those experienced in

CORAL REEF CONDITION WITH CHAETODONTIDAE FISH AS THE INDICATORS IN THE WATERS OF THE SAMBER GELAP ISLAND OF KOTABARU, SOUTH KALIMANTAN

Russian Journal of Agricultural and Socio-Economic Sciences, 2020
Coral reefs are ecosystems with a very high diversity of species that function as dwellings and grow for other biota. Coral reef is a community of organisms that live on the bottom of the water and in the form of limestone (CaCO3) which is strong enough ...
