“…We propose several biological reasons that temperature, specifically maximum temperature of the warmest month, may be exerting a greater evolutionary pressure on starlings in comparison to precipitation and aridity. First, range expansion in invasive starling populations is strongly associated with suburban and rural areas (Zufiaurre et al, 2016), owing to a preference for grazing in open pasture land (e.g. agricultural areas, fields, and parks), and the excessive roosting opportunities provided by urban structures.…”

“…It is possible that some of the above problems could be avoided if genetic groups resulting from historic introduction regimes were analysed separately, however, even in a scenario with only one introduction site, the artefacts of range expansion still need to be contended with. Historic starling introduction sites represent relatively favourable conditions for the species (Zufiaurre et al, 2016), and during range expansion, the starlings have slowly colonised less favourable areas, moving into the arid regions of inland and Western Australia. As a result, the expansion trajectory between introduction sites and range edge may co-occur with environmental clines.…”

A detailed understanding of population genetics in non-native populations helps us to identify drivers of successful introductions. However, separating adaptive change from local signatures of founding populations represents a conceptual and technical difficulty when dealing with invasive populations. The history of introductions, as well as the process of range expansion, can confound interpretation of putative adaption in response to a novel environment. Here, we investigate putative signals of selection in Australian populations of introduced common starlings, Sturnus vulgaris, by examining population wide Single Nucleotide Polymorphisms (SNPs) and identifying SNP outliers associated with environmental variables. We determine that geographic distance plays a strong role in the genetic structure of populations, and that this is most likely strongly influenced by genetic differences in the founding populations, as well as modern day population connectivity.Examining candidate SNPs under putative selection indicated that local adaption has likely occurred, however, strong patterns in genetic variation, likely from founding populations, were visible in SNPs that were strongly associated with environmental variables. When examining putative adaption in invasive populations, we encourage critical interpretation of signatures of selection. Even strongly associated loci and environmental variables, when examined closely, may contain distinct footprints of invasion history or invasion expansion gradients, confounding analysis of the history of selection in these populations.

“…Las modificaciones antrópicas del ambiente pueden actuar como disparadores de una invasión (McNeely et al 2001), lo que lleva a postular el principio que dice que "la construcción de un invasor es más una cuestión humana que biológica". Este parece ser el caso de los estorninos, cuya expansión está en gran medida favorecida por las actividades agrícolas y ganaderas y por la urbanización (Kessel 1953, Smith & Bruun 2002, Zufiaurre et al 2016. El avance de la especie depende en cierto grado de su capacidad natural de desplazamiento pero también de "saltos" mediados por el transporte voluntario de ejemplares como aves de jaula (Suarez et al 2001), lo que requiere acciones de educación, regulación y control.…”

El día 11 de septiembre de 2015 se desarrolló la mesa redonda “Invasión del estornino pinto (Sturnus vulgaris) en Argentina”, en el marco de la XVI Reunión Argentina de Ornitología organizada por la Sección Ornitología del Museo de La Plata (Facultad de Ciencias Naturales y Museo, Universidad Nacional de La Plata). En esa oportunidad se informó acerca de las características de la especie, de las consecuencias de su introducción en distintos países, del estado actual de la invasión en Argentina y de los antecedentes relacionados con su control. Además, se realizó una actividad en la que los participantes propusieron medidas de acción prioritarias para el manejo de la especie a nivel local, regional y nacional. En esta contribución resumimos los aspectos más relevantes de la reunión y las conclusiones de la misma.

“…In Argentina, it was introduced by the bird traffic and the first record in the wild dates from 1987 in Buenos Aires city (Pérez, 1988). Since then, it has expanded 500 km through Buenos Aires province (LI, unpublished data) and new population establishments have been recorded in provinces from the north and the center of Argentina (Peris et al, 2005;Zufiaurre et al, 2016). In 1998 it was declared a harmful species by the Secretariat of Environment of the Nation.…”

Lichens in the nests of European starling Sturnus vulgaris serve a mate attraction rather than insecticidal function

The European starling Sturnus vulgaris is a hole-nesting bird in which the male builds a voluminous nest using a wide variety of materials such as twigs, grass, leaves, feathers, and lichens. The function of lichens in starling nests has not been assessed until now and we hypothesize that this material is related to a mate attraction function or is used to protect nestlings from parasites due to the presence of secondary compounds with insecticidal effects with the lichens. We aimed to identify the lichen species and frequency of lichen use in European starling nests, and to determine if the presence of this material is correlated with mate attraction or with an insecticidal function. We found lichens in 45% of nests, mainly represented by Ramalina celastri. The lichens were added to the nests mainly before the beginning and at the end of nest building and egg-laying started earlier in nests with lichens than those without lichens. No association was found between the presence of lichen and the intensity of Philornis larvae (Diptera), a parasite that infests starling nestlings. Our results suggest that the addition of lichens could be related to mate attraction and a stimulus for the beginning of egg-laying but did not have an antiparasitic function in European starling nests.
