Geographical variation in floral traits of the tree tobacco in relation to its hummingbird pollinator fauna
(Wiley Blackwell Publishing, Inc, 2007-04)
Nicotiana glauca, a hummingbird pollinated plant, exhibits geographical variation in several floral traits. We examined whether geographical differentiation occurred for different flower characters and if this differentiation ...
Is natural selection promoting sexual dimorphism in the Green-backed Firecrown Hummingbird (Sephanoides Sephaniodes)?
(2009)
In many hummingbird species there is an opposite pattern of sexual dimorphism in bill length and other morphometric measures of body size. These differences seem to be closely related with differences in foraging ecology ...
Quantity versus quality: identifying the most effective pollinators of the hummingbird-pollinated Vriesea rodigasiana (Bromeliaceae)
(Springer WienWienAustria, 2013)
A twelve-month field study of the West African Thrush Turdus pelios (Passeriformes:Muscicapidae).Part 1:food and feeding ecology

Range overlap between the sword-billed hummingbird and its guild of long-flowered species: An approach to the study of a coevolutionary mosaic
(Public Library of Science, 2018-12)
The coevolutionary process among free-living mutualists with extremely long matching traits may favor the formation of mutualistic interaction networks through coevolutionary escalation, complementarity and convergence. ...
Do morphometric measurements allow sex discrimination in Mockingbirds (Mimus sp)?
(Society for the Improvement of Science, 2016-10)
Sexual dimorphism in birds may be expressed as differences in body size, plumage, color and/or behavior. Many species are monomorphic in color, making sex determination difficult in the field. An example of the latter are ...
Genetic parameters for tonic immobility, body weight, and morphological traits of the red-winged tinamou (Rhynchotus rufescens)
(Springer, 2020-01-01)
This study was carried out to estimate genetic parameters for morphology, body weight, and tonic immobility traits in the red-winged tinamou (Rhynchotus rufescens). Information on 690 birds was used and genetic parameters ...
Hydrochemical parameters and biometric data of fish species from the Bororé, Billings Reservoir, São Paulo, Brazil
(Universidade Federal de São Paulo, 2022-02-04)
A pesca artesanal é uma atividade importante no reservatório Billings (São Paulo, Brasil) e há uma escassez de dados biométricos de peixes nesta região. Deste modo, é importante fornecer dados sobre a ictiofauna que possam ...
