However, the effects of these systems on most marine mammals are largely unknown, preventing the establishment of guidelines that will minimize However, the effects of these systems on most marine mammals are largely unknown, preventing the establishment of guidelines that will minimize animal disturbance.
In this study, we evaluated the behavioral responses of coastal bottlenose dolphins Tursiops truncatus and Antillean manatees Trichechus manatus manatus to small multi-rotor UAS flight.
The quadcopters were equipped with high-resolution cameras to observe dolphins during of these flights, and manatees during 73 flights.
Dolphins responded to UAS flight at altitudes of 11—30 m and responded primarily when they were alone or in small groups. Single dolphins and one pair responded to the UAS by orienting upward and turning toward the aircraft to observe it, before quickly returning to their pre-response activity.
A higher number of manatees responded to the UAS, exhibiting strong disturbance in response to the aircraft from 6 to m. Manatees changed their behavior by fleeing the area and sometimes this elicited the same response in nearby animals.
These findings suggest that the invasiveness of UAS varies across individuals, species, and taxa. We conclude that careful exploratory research is needed to determine the impact of multi-rotor UAS flight on diverse species, and to develop best practices aimed at reducing the disturbance to wildlife that may result from their use.Ecopath with Ecosim (EwE) is a free ecological/ecosystem modeling software suite.
EwE has three main components: Ecopath – a static, mass-balanced snapshot of the system; Ecosim – a time dynamic simulation module for policy exploration; and Ecospace – a spatial and temporal dynamic module primarily designed for exploring impact and placement of protected areas.
Marine Biology Research Paper Marine Biology The field of marine biology, the study of organisms within their environment of an ocean, lake, or river, has a very broad range of occupations. Marine biologists try to discover how organisms grow and develop, how they get food, how their bodies function, and how their life relations correspond to.
The Sirenia, commonly referred to as sea cows or sirenians, are an order of fully aquatic, herbivorous mammals that inhabit swamps, rivers, estuaries, marine wetlands, and coastal marine waters.
The Sirenia currently comprise the families Dugongidae (the dugong) and Trichechidae (manatees) with a total of four species. The Protosirenidae (Eocene sirenians) and Prorastomidae (terrestrial.
