Seasonal dynamics, geographical range size, hosts, genetic diversity and phylogeography of Amblyomma sculptum in Argentina
(Elsevier Gmbh, 2018-07)
The aim of this work was to generate knowledge on ecological aspects of Amblyomma sculptum in Argentina, such as seasonal dynamics, geographical range size, hosts, genetic diversity and phylogeography. Adult and immature ...
Geographical differentiation in floral traits across the distribution range of the Patagonian oil-secreting Calceolaria polyrhiza: Do pollinators matter?
(Oxford University Press, 2013-09)
Background and Aims: The underlying evolutionary processes of pollinator-driven floral diversification are still poorly understood. According to Grant-Stebbins model speciation begins with adaptive local differentiation ...
Estimating the geographic range of a threatened shark in a data-poor region: Cetorhinus maximus in the South Atlantic Ocean
(Oxford University Press, 2015-10)
The distribution of the planktivorous basking shark Cetorhinus maximus is influenced by zooplankton abundance at small scales and temperature at medium scales in the North Atlantic. Here, we estimate the distribution of ...
Geographical distribution and habitat characterization of Poa schizantha (Poaceae), a narrow endemic of the coastal sand dunes of the southern Pampas, Argentina
(Wiley Blackwell Publishing, Inc, 2020-10-18)
Poa schizantha is a dioecious, psammophilous grass endemic to Atlantic coastal dunes in Argentina. We quantified the distribution area of this rare endemic species and characterized its habitat in the southern Pampas region. ...
Phenotypic selection mosaic for flower length influenced by geographically varying hawkmoth pollinator proboscis length and abiotic environment
(Wiley Blackwell Publishing, Inc, 2019-09)
Biotic and abiotic context may affect the intensity of interspecific interactions and subsequently drive locally particular phenotypic selection patterns on interacting traits. We evaluated the geographical variation of ...
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. ...
Updates on geographic range and synonymies in species of Podocoma (Asteraceae: Astereae)
