Marine Biodiversity, 2016
After the first detection of the Indo-Pacific lionfish (Pterois volitans) off the Florida coast (USA) approximately 30 years ago, its populations have continued spreading throughout the Western Atlantic. The invasive lionfish is a threat to the marine ecosystems because individuals reproduce fast, reach high population densities, prey on many taxa ...

Development of ALACRANE: A Mobile Robotic Assistance for Exploration and Rescue Missions
2007 IEEE International Workshop on Safety, Security and Rescue Robotics, 2007The paper presents ALACRANE, a new mobile robot assistant for exploration and rescue missions with dexterous load manipulation capability. ALACRANE consists of a tracked vehicle with a 4-DOF articulated arm, whose end-effector is an independent pair of 3-DOF manipulators (LR-Arms) plus a common rotation on the main arm wrist.

Terrace climbing of the Alacrane mobile robot with cooperation of its onboard arm
2012 12th IEEE International Workshop on Advanced Motion Control (AMC), 2012Alacrane is a hydraulic mobile manipulator for search and rescue in disaster areas and natural environments, where surmounting elevations such as rubble mounds and terraces is usually required. The paper describes the autonomous terrace climbing maneuver of this mobile robot with the help of its powerful arm. During this operation, the arm is used both

Coral pinnacle sedimentation, Alacran Reef lagoon, Mexico
Journal of Sedimentary Research, 1966Abstract Coral pinnacles growing in Alacran Reef lagoon can be characterized by three different depositional environments. These are: (1), Pinnacle crest, an area of living colonial stony corals and unconsolidated sediment which is poorly sorted 2.5 phi coral sand, having relatively high permeability, 20% calcite, 1.6% magnesium, and ...
