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.

First Non‐Invasive Monitoring of Fecal Steroids in Greater Caribbean Manatees (Trichechus manatus manatus)

Zoo Biology, EarlyView.
This study established the first fecal hormonal reference values (P4/E2) for the Greater Caribbean manatee. Using non‐invasive ELISA, the authors found no significant differences between mature and immature females, highlighting that long‐term monitoring and ultrasounds are essential to fully understand their complex reproductive cycles.

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model

Integrative Zoology, EarlyView.
UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

Extent and toxicity of contaminated marine sediments in Southeastern Florida [PDF]

, 2004
Thirty sites were sampled in southern Biscayne Bay and Manatee Bay in December 1999 to determine the extent of toxicity in sediments. Analyses and assays included: pesticides and phenols in seawater; chemical contaminants in sediment; amphipod mortality,

A Composite Genome Approach to Identify Phylogenetically Informative Data from Next-Generation Sequencing

, 2014
We have developed a novel method to rapidly obtain homologous genomic data for phylogenetics directly from next-generation sequencing reads without the use of a reference genome.

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 ...

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Scarring of Florida’s seagrasses: assessment and management options [PDF]

, 1995
Management programs that address scarring of seagrasses should be based on an approach that involves (1) education, (2) channel marking, (3) increased enforcement, and (4) limited-motoring zones. Aerial monitoring and photography of the managed area

Corneal transplantation: Restoring sight to the blind

Acta Ophthalmologica, EarlyView.
Abstract Corneal blindness is one of the leading causes of vision loss worldwide. Transplantation of the cornea can restore vision and make blind patients see again. Corneal transplant surgery has undergone major evolution in recent decades with the advent of minimally invasive lamellar surgical approaches such as DMEK and DALK.
