Pollinator response to flower color polymorphism and floral display in a plant with a single-locus floral color polymorphism: consequences for plant reproduction
(Springer Tokyo, 2012-03)
Variation in flower color, particularly polymorphism, in which two or more different flower color phenotypes occur in the same population or species, may be affected or maintained by mechanisms that depend on pollinators. ...
Morph-specific strategies of habitat use in a color polymorphic marine shrimp
(University of North FloridaJacksonville, 2014)
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 ...
Morph-specific genetic and environmental variation in innate and acquired immune response in a color polymorphic raptor
(Springer Heidelberg, 2015-08)
Genetic color polymorphism is widespread in nature. There is an increasing interest in understanding the adaptive value of heritable color variation and trade-off resolution by differently colored individuals. Melanin-based ...
Variation of thermal parameters in two different color morphs of a diurnal poison toad, Melanophryniscus rubriventris (Anura: Bufonidae)
(Elsevier, 2014-02)
We study the variation in thermal parameters in two contrasting populations Yungas Redbelly Toads (Melanophryniscus rubriventris) with different discrete color phenotypes comparing field body temperatures, critical thermal ...
A lost species or the loss of stripes? The case of Contomastix lizards from Cabo Polonio, Uruguay, with observations on C. Lacertoides (Duméril & Bibron) and cnemidophorus grandensis Cope (Squamata, Teiidae)
(2013-03-06)
The main goal of this manuscript is the reevaluation of the taxonomic status of the teiid lizard Contomastix charrua, known only from Cabo Polonio, a small coastal rocky outcrop in southeastern Uruguay. This species was ...
Efeitos do ágar no crescimento de explantes e na formação de calos em morfos pigmentares de Gracilaria domingensis (Kützing) Sonder ex Dickie (Gracilariales, Rhodophyta)
(Sociedade Botânica de São Paulo, 2009)
Os efeitos da concentração de ágar no crescimento de explantes e na formação de calos foram avaliados em culturas axênicas de gametófitos femininos de morfos de coloração verde e vermelha de Gracilaria domingensis (Kützing) ...
Systematics of the Tawny-bellied seedeater (Sporophila Hypoxantha): II: taxonomy and evolutionary implications of the existence of a new tawny morphSistemática de Sporophila Hypoxantha: II: taxonomía e implicancias evolutivas de la existencia de una nueva forma en Sporophila
(Cooper Ornithological Society, 2011-08)
The capuchinos, a subset of the genus Sporophila, represent a radiation of seedeaters characterized by little genetic differentiation, virtually no change in bill and body shape, marked plumage differences on a common ...
