Establishing an Ecuadorian Isoscape: The Importance of Baseline Strontium Data in a Volcanic Landscape. [PDF]

Am J Biol Anthropol
ABSTRACT Objectives Strontium isotopes (87Sr/86Sr) have been used worldwide to track migrations and identify nonlocal individuals in the past. In South America, these studies often use comparative baseline maps, or isoscapes, established by samples from archaeological fauna and geologic formations. However, baseline research has focused on coastal Peru

The taxonomic status of Farlowella colombiensis Retzer & Page 1997 with comments on species of the F. acus species group (Loricariidae: Loricariinae). [PDF]

J Fish Biol
Abstract The genus Farlowella has been historically challenging, in part due to the difficulty in defining diagnostic characters for defining and identifying the species. Farlowella colombiensis is one such example, whose diagnostic characters are based on caudal‐fin colour pattern, ventral pattern of body cover and anatomical details of the head, such
