Several cytogenetic markers show chromosomal diversity in the fish such as "armoured catfish". Although studies have characterized many species in the major genera representing these Siluridae, particularly in the genus Hypostomus Lacépède, 1803, trends in chromosome evolution of this group remain unclear. The Paraíba do Sul river basin contains the armoured catfish Hypostomus affinis Steindach...

Shoreline armouring has progressively affected the coastal landscapes of countries all over world, and construction will increase in coming years as a consequence climate change. Armouring potential to affect environments induce changes abundance diversity marine communities, its effects might by increased wide adoption.

A new trigonotarbid (Arachnida: Trigonotarbida: Trigonotarbidae) is described as Archaeomartus roessleri n. sp. from the Upper Carboniferous (Pennsylvanian; Namurian B, higher Marsdenian) of Hagen-Vorhalle, Germany. Originally assigned to Trigonotarbus johnsoni Pocock, 1911, our new fossil has a distinctly lobed carapace and thus resembles more closely the Early Devonian species Archaeomartus l...
