TL;DR: The three living species of manatees, Trichechus manatus, Amazonian and T. inunguis, are distributed across the shallow tropical and subtropical waters of America and the western coast of Africa.

TL;DR: A signal of hybridization was seen in each species, being detected in the X chromosome of P. (Phyllophaga) aff capillata and Lyogenys fuscus, and in a small autosomal bivalent of FISH.

TL;DR: The study presents detailed karyotipic descripitions of three Rutelinae species (Geniates borelli, Macraspis festiva and Pelidnota pallidipennis), and two Dynastinae Species (Lygirus ebenus and Strategus surinamensis hirtus) with special emphasis on the distribution and variability of constitutive heterochromatin and the nucleolar organizer region (NOR).

TL;DR: The presence of such an association of 5S rDNA and H3 histone in mussels and arthropods (beetles, grasshoppers and crustaceans) suggests that this linked configuration could represent an ancestral pattern for invertebrates.

TL;DR: The occurrence of B chromosomes in all nine R. brasiliensis populations analyzed indicates that they are widely distributed in Northeastern Brazil, and the small amount of interpopulation variation found for B chromosome prevalence suggests the existence of high gene flow, presumably due to the abundance of this grasshopper species on several types of vegetation and its relatively high flight capability.
