Detecting Convergence of Amino Acid Physicochemical Properties Underlying the Organismal Adaptive Convergent Evolution. [PDF]

open access: yesMol Ecol Resour
ABSTRACT Many studies have proposed various comparative genomic methods to probe the molecular basis for adaptive functional convergence between species, conventionally by detecting the convergence of amino acid states between orthologous protein sequences of these species or lineages.

Color Vision in the Manatee (Trichechus manatus)

open access: yesVision Research, 1996
Four manatees were trained to discriminate between a colored stimulus and a shade of gray in a two-fold simultaneous choice situation. The colors blue, green, red and blue-green were tested against shades of gray varying from low to high relative brightness. The animals distinguished both blue and green from a series of grays but failed to discriminate

Disparity of turbinal bones in placental mammals. [PDF]

open access: yesAnat Rec (Hoboken)
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

Disseminated toxoplasmosis in Antillean manatees Trichechus manatus manatus from Puerto Rico [PDF]

open access: yesDiseases of Aquatic Organisms, 2012
Necropsies were conducted on 4 Antillean manatees Trichechus manatus manatus that were stranded in single events on the coastal beaches of Puerto Rico from August 2010 to August 2011. Three manatees were emaciated and the gastrointestinal tracts were devoid of digesta.

Distribution and conservation status of the Antillean manatee (Trichechus manatus manatus) in Honduras [PDF]

open access: yesLatin American Journal of Aquatic Mammals, 2014
The Antillean manatee, Trichechus manatus manatus, is among the most threatened mammals in Honduras, yet the last published study is from 1980. Since then, the North Coast of Honduras has experienced rapid population growth and land cover change possibly causing habitat loss for manatees.
