Bird-mediated selection on fruit display traits in Celtis ehrenbergiana (Cannabaceae)
(Evolutionary Ecology Ltd, 2014-08)
Background: In mutualistic interactions of fleshy-fruited plants and seed-dispersing birds, dispersers act as natural selection agents on fruit display traits. Bird-mediated phenotypic selection on maternal and seed level ...
Pollinator-mediated selection and experimental manipulation of the flower phenotype in Chloraea bletioides
(WILEY-BLACKWELL, 2010-05-20)
1. While many studies of flower evolution have relied on the assessment of selection coefficients,
these estimates represent correlative evidence of selection. Few studies have combined correlative
with experimental ...
Environment-dependent regime of longevity selection in the chromosomally polymorphic species Leptysma argentina (Acrididae: Orthoptera)
(University Florence Botany Institute, 2012-09)
In previous papers it was reported that a Robertsonian translocation (centric fusion) affected external phenotype in the grasshopper Leptysma argentina and that thorax height was the target of adult viability selection. ...
SIZE AS A LINE OF LEAST RESISTANCE II: DIRECT SELECTION ON SIZE OR CORRELATED RESPONSE DUE TO CONSTRAINTS?
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
Evolutionary change in New World Monkey (NWM) skulls occurred primarily along the line of least resistance defined by size (including allometric) variation (g(max)). Although the direction of evolution was aligned with ...
Direct, indirect and simultaneous selection as strategies for alfalfa breeding on forage yield and nutritive value
(Pesquisa Agropecuária Tropical, 2019)
Patterns of phenotypic selection for oil and nectar in Monttea aphylla (Plantaginaceae) in a geographic mosaic of interactions with pollinators
(Elsevier Gmbh, 2017-07)
Oil-flower species are highly specialized attracting a narrow group of oil-collecting bees in contrast to nectar-flower species visited by a wide diversity of pollinators. The vast majority of the oil species lack nectar ...
Partitioning the relative fitness effects of diet and trophic morphology in the threespine stickleback
(Evolutionary Ecology Ltd, 2011-07-01)
Background: Numerous models show that if morphology and diet are correlated, frequency-dependent competition will lead to fitness differences among phenotypically dissimilar individuals within a species.Hypothesis: Selection ...
