The use of drones to study marine animals shows promise for the examination numerous aspects their ecology, behaviour, health and movement patterns. However, responses some phyla presence varies broadly, as do general operational protocols used them. Inconsistent methodological approaches could lead difficulties comparing studies can call into question repeatability research. This review draws on current literature researchers with a wealth practical experience outline idiosyncrasies...

Abstract Information from 15 satellite‐tracked Antillean manatees ( Trichechus manatus ) was analyzed in order to assess individual movements, home ranges, and high‐use areas for conservation decisions. Manatees were captured Chetumal Bay, Mexico, tagged with Argos‐monitored satellite transmitters. Location of the physical characteristics assessed describe habitat properties. Most traveled freshwater sources. The Maximum Area Size MAS each manatee determined using observation‐area method....
Dolphins of the genus Stenella occur in pelagic waters both tropical and warm-temperate oceans. Three species, Atlantic spotted dolphin (Stenella frontalis), pantropical (S. attenuata), spinner longirostris) are abundant worldwide, but Caribbean Basin they have been poorly studied information on their distribution patterns is scarce. Specifically, Colombia's remote Seaflower Biosphere Reserve (SFBR) S. attenuata has reported occasionally, frontalis longirostris never recorded before. To...
The Vulnerable Antillean manatee Trichechus manatus (Mammalia, Sirenia) is threatened by hunting, entanglement in fishing nets and habitat degradation but most knowledge of the species comes from coastal estuarine populations. We therefore studied an population located >1,100 km Caribbean coast, Orinoco River Colombia, during 2001–2005. To verify occurrence to investigate its use throughout annual hydrological cycle, we carried out surveys for manatees feeding signs over c. 40 River, between...
Manatees, as well other sirenians, are aquatic, opportunistic herbivores. Knowledge of their diet is important to determine habitat requirements. This the first study manatee in México. Our main objective was identify plant species eaten by manatees Chetumal Bay, and establish if composition varied climatic season, sex or age class. We compared epidermal fragments found feces with histological descriptions permanent collections suspected plants algae. Thirty-six fecal samples nine tract...
Abstract Assessing the body condition of wild animals is necessary to monitor health population and critical defining a framework for conservation actions. Body indices (BCIs) are non-invasive relatively simple means assess individual animals, useful addressing wide variety ecological, behavioral, management questions. The Antillean manatee ( Trichechus manatus ) an endangered subspecies West Indian manatee, facing threats from mostly human-related origins. Our objective was define specific...
ABSTRACT Behavioural and acoustic plasticity allow cetaceans to exploit a variety of habitats developing strategies overcome increasingly demanding anthropogenic pressures. Bottlenose dolphins are known compete with artisanal fishing along the southwestern coast Gulf Mexico, but extent marine traffic impacts on species is unknown. We investigated dolphin behavioural dynamics through unmanned aerial vehicles (UAV) recordings in two zones off Alvarado, Veracruz, high (HVP) low‐vessel presence...
ABSTRACT Boat‐based dolphin‐watching tourism targeting common bottlenose dolphins ( Tursiops truncatus ) in the Mexican Caribbean is an increasing activity. Yet, tour boat compliance with local guidelines has not been evaluated, and impacts of these activities on dolphin populations remain unknown. To address this gap, we used boat‐based observations aerial drone video recordings to evaluate described dolphins' behavioral responses. We assessed adherence key guidelines, including observation...
Abstract Context Unmanned aerial vehicles or drones are powerful tools for wildlife research. Identifying the impacts of these systems on target species during operations is essential to reduce risks disturbance wildlife, minimise bias in behavioural data, and establish better practices their use. Aims We evaluated responses captive Antillean manatees overhead flight a small drone. Methods used ground videos compare manatee activity budgets respiration rates three 15-min sampling periods:...

Abstract The Antillean manatee Trichechus manatus is a cryptic mammal that inhabits, among other areas, murky rivers and estuaries of Central South America. difficulty in detecting counting manatees an obstacle to monitoring their population status, as traditional count sampling unsuitable. We conducted quantitative analysis the distribution abundance across its known range French Guiana, based on data from range-wide line transect visual survey combined with side-scan sonar survey,...
