Bottlenose Dolphins and Antillean Manatees Respond to Small Multi-Rotor Unmanned Aerial Systems

Frontiers in Marine Science, 2018
Unmanned aerial systems (UASs) are powerful tools for research and monitoring of wildlife. However, the effects of these systems on most marine mammals are largely unknown, preventing the establishment of guidelines that will minimize animal disturbance.

Partners or passengers? Revisiting the association between diatoms and aquatic animals

Biological Reviews, EarlyView.
ABSTRACT Numerous studies have revealed the importance of research on the communities capable of colonizing animal surfaces (epibionts) and the animals on which they live (basibionts). Very few studies have considered epizoic diatoms, and there are gaps and biases in our knowledge, including the choice of basibionts, the methods used, and the habitats ...

Using Pooled Local Expert Opinions (PLEO) to Discern Patterns in Sightings of Live and Dead Manatees (Trichechus senegalensis, Link 1785) in Lower Sanaga Basin, Cameroon. [PDF]

PLoS ONE, 2015
We aimed at unveiling patterns in live and dead manatee sightings in the Lower Sanaga Basin, Cameroon. For this purpose, the expert opinions of 133 local fishers were collected during in-person interviews, distilled using categorical data analysis, and ...

Exploring consumer preferences for wild meat and other animal proteins in Gamba, Gabon: Implications for conservation and management of natural resources alongside extractive industry

People and Nature, EarlyView.
Abstract The town of Gamba in southwest Gabon represents an exceptional example of how the development of an extractive industry (in this case oil production) may impact wild meat consumption in an area of global importance for biodiversity. Studies in the 1990s identified an active wild meat trade; however, no studies have been undertaken since, and ...

Development and Improvement of Habitat Suitability Criteria for Instream Habitat Assessments Conducted in Support of Environmental Flows in Florida

River Research and Applications, EarlyView.
ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...

Interpretable Individual Manatee Identification Using Sketch Images and Deep Neural Networks

IEEE Access
Individual manatee identification is crucial for understanding their behaviors, traits, threats, population health, etc. Traditional methods rely on photo-identification, which entail extensive expert efforts during and after the field studies.

Distribution of the Antillean manatee (Trichecus manatus manatus) in the Alvarado Lagoon System (Veracruz, Mexico)

Ciencias Marinas, 2012
The Antillean manatee (Trichechus manatus manatus) is considered endangered in Mexico. Local extinctions have been documented in the northern Gulf of Mexico, and the only remaining population with a northern distribution is found in the Alvarado Lagoon ...

Adjusting Our Thinking About Feeding Animals: Fiber as the Metric for Mimicking Natural Diets

Zoo Biology, EarlyView.
A typical effect of the change of an animal group to a diet higher in fiber: juveniles keep growing, animals of ideal body weight maintain their weight, and obese individuals lose weight. ABSTRACT Free‐ranging animals often ingest markedly different diets than their counterparts under human care, whether companion animals, production animals, or zoo ...

Effects of Roscovitine and Serum Starvation on the Viability and G0/G1 Synchronization in Somatic Cells from the Antillean Manatee (Trichechus manatus manatus, Linnaeus 1758)

Zoo Biology, EarlyView.
ABSTRACT The success of nuclear reprogramming techniques, including the G0/G1 synchronization of somatic cells, depends on species‐specific optimization. While roscovitine and serum starvation have been successfully applied in domestic and wild terrestrial mammals, their use in aquatic mammals remains poorly investigated.
