Morphological variation of the rare psammophilous species Apostolepis gaboi (Serpentes, Dipsadidae, Elapomorphini)
(Magnolia Press, 2018-05-10)
Apostolepis gaboi was described based only on the holotype found in the Queimadas, state of Bahia, northeastern Brazil. Since its original description, no additional specimens were reported in literature and the species ...
Wing patterning gene redefines the mimetic history of Heliconius butterflies
(2011)
The mimetic butterflies Heliconius erato and Heliconius melpomene have undergone parallel radiations to form a near-identical patchwork of over 20 different wing-pattern races across the Neotropics. Previous molecular ...
Early patterns of Andean diversification, genomic and color patterns variation across the Metallura tyrianthina complex of the Northern Andes
The highly variable topography, the climatic history and the great variety of niches of the Andes mountain range have had major contributions to the formation and maintenance of the genetic and morphological diversity of ...
Remote phenology: Applying machine learning to detect phenological patterns in a cerrado savanna
(2012-12-01)
Plant phenology has gained importance in the context of global change research, stimulating the development of new technologies for phenological observation. Digital cameras have been successfully used as multi-channel ...

(2012-04)
Entre los animales que mejor ejemplifican la comunicación visual están los lagartos de la familia Iguanidae. Muchas de sus especies tienen estructuras y colores llamativos en combinación con patrones conductuales diversos. ...
Data-Driven Symbol Defi nition for Color Shift Keying in Screen Camera Communications
(Universidad Nacional Tecnológica de Lima Sur, 2021)
Aiming to increase the data rate in screen camera communications, we intend to define symbols to be used in an M-ary color shift keying modulation scheme. With regard to the R, G, B format of a JPEG image, we generate ...
Sociospatial structuration of alternative breeding strategies in a color polymorphic raptor
(Oxford University Press, 2015-04)
It has been proposed that niche and behavioral processes may promote the coexistence of alternative color morphs in discrete areas. In this study, we tested the hypothesis that alternative melanin-based phenotypes perform ...
The pattern of color change in small mammal museum specimens: Is it independent of storage histories given museum-specific conditions?
(BioMed Central, 2018-07)
Objective: Determination of color and evaluating its variation form the basis for a broad range of research questions. For studies on taxonomy, systematics, etc., resorting to mammal specimens in museum collections has a ...
