“…Numerical responses will also be affected with, for example, many reptile species exhibiting temperature dependent sex determination (Laloe et al 2014). Phenological shifts can also influence food availability and hence growth and abundance (Visser and Both 2005), potentially increasing the impact disparity between native and invader (Lediuk et al 2014).…”

Invasive alien species continue to arrive in new locations with no abatement in rate, and thus greater predictive powers surrounding their ecological impacts are required. In particular, we need improved means of quantifying the ecological impacts of new invasive species under different contexts. Here, we develop a suite of metrics based upon the novel Relative Impact Potential (RIP) metric, combining the functional response (consumer per capita effect), with proxies for the numerical response (consumer population response), providing quantification of invasive species ecological impact. These metrics are comparative in relation to the eco-evolutionary baseline of trophically analogous natives, as well as other invasive species and across multiple populations. Crucially, the metrics also reveal how impacts of invasive species change under abiotic and biotic contexts. While studies focused solely on functional responses have been successful in predictive invasion ecology, RIP retains these advantages while adding vital other predictive elements, principally consumer abundance. RIP can also be combined with propagule pressure to quantify overall invasion risk. By highlighting functional response and numerical response proxies, we outline a user-friendly method for assessing the impacts of invaders of all trophic levels and taxonomic groups. We apply the metric to impact assessment in the face of climate change by taking account of both changing predator consumption rates and prey reproduction rates. We proceed to outline the application of RIP to assess biotic resistance against incoming invasive species, the effect of evolution on invasive species impacts, application to interspecific competition, changing spatio-temporal patterns of invasion, and how RIP can inform biological control. We propose that RIP provides scientists and practitioners with a user-friendly, customisable and, crucially, powerful technique to inform invasive species policy and management.

“…En la región norpatagónica de la Argentina, donde predominan las lluvias en otoño-invierno y el estrés por falta de agua se hace frecuente en el período estival (Barros et al, 1983;Conti, 1998), las presiones de selección natural favorecerían a aquellas especies que exhiben su crecimiento estacional entre fines de invierno y primavera temprana (como R. rubiginosa, M. oblongum, P. avium y J. communis). Es destacable que la mayoría de estas especies son exóticas invasoras en Patagonia (Schüttler & Karez, 2009), lo cual indicaría que el uso espacio-temporal atípico que las caracteriza podría ser uno de los componentes de su éxito (Lockwood et al, 2007;Wolkovich & Cleland, 2011;Lediuk et al, 2014Lediuk et al, , 2016.…”

“…Cada una de las especies leñosas que conviven en un bosque posee atributos morfológicos, fisiológicos y fenológicos que la asocian a un determinado grupo funcional, por vincularse tales atributos a las respuestas de la especie a las condiciones ambientales e incidir en las interacciones intra-e inter-específicas (Reich et al, 1998;Diaz et al, 1999;Cornelissen et al, 2003;Díaz et al, 2016). Por ejemplo, en una comunidad boscosa pueden habitar especies que favorecen la regeneración de otras (Connell & Slatyer, 1977;Henríquez & Lusk, 2005;Lediuk et al, 2014) y especies que incrementan la probabilidad de generación y propagación de incendios (Kitzberger et al, 1997;LaRade & Bork, 2011). Dentro de este esquema, las especies exóticas pueden ocupar "nichos vacantes" dentro de la comunidad o asemejarse a las especies nativas respecto de sus grupos funcionales, compitiendo con éstas en mayor o menor medida por los recursos disponibles.…”

El crecimiento y la arquitectura de las especies leñosas que habitan los bosques inciden en la dinámica de estas comunidades. El objetivo principal de este estudio fue mejorar la comprensión de la dinámica de los cipresales patagónicos a partir del análisis del crecimiento longitudinal y de la arquitectura de las especies leñosas más abundantes en esas comunidades, las nativas: Aristotelia chilensis, Berberis microphylla, Lomatia hirsuta, Maytenus boaria, Myoschilos oblongum y Schinus patagonicus; y las exóticas: Juniperus communis, Prunus avium, Pseudotsuga menziesii y Rosa rubiginosa. El crecimiento longitudinal del eje principal no se relacionó necesariamente con el aumento en altura de las plantas durante el período de estudio (2012-14). Se registraron decrecimientos en altura en todas las especies excepto en P. menziesii y P. avium, exóticas para Patagonia. La mayoría de los individuos presentaron notables desviaciones de su eje principal de la vertical, las que se correlacionaron negativamente con la longitud del brote distal y con la variación en altura de las plantas. Se agruparon las especies en cuatro grupos funcionales, de acuerdo a su arquitectura y crecimiento. La invasión de los cipresales por parte de especies exóticas como P. menziesii y P. avium, asociadas a grupos funcionales distintos a los de las especies nativas más frecuentes, podría impactar significativamente en la dinámica de esas comunidades promoviendo el reemplazo de las especies nativas por las exóticas dominantes.

“…Pollinators tend to favour early flowering, particularly if it involves extending the pollination season (Elzinga et al, 2007;Munguía-Rosas et al, 2011;Rafferty and Ives, 2011). Unsurprisingly, the exploitation of new temporal niches with reduced competition for biotic and abiotic resources has been found to benefit invasive species (Godoy et al, 2009a, b;Lediuk et al, 2014) and is believed to benefit invasive acacias (Gibson et al, 2011) although experimental data is not yet available for this group of plants.…”

Two invasive acacia species secure generalist pollinators in invaded communities

a b s t r a c tExotic entomophilous plants need to establish effective pollinator interactions in order to succeed after being introduced into a new community, particularly if they are obligatory outbreeders. By establishing these novel interactions in the new non-native range, invasive plants are hypothesised to drive changes in the composition and functioning of the native pollinator community, with potential impacts on the pollination biology of native co-flowering plants. We used two different sites in Portugal, each invaded by a different acacia species, to assess whether two native Australian trees, Acacia dealbata and Acacia longifolia, were able to recruit pollinators in Portugal, and whether the pollinator community visiting acacia trees differed from the pollinator communities interacting with native co-flowering plants. Our results indicate that in the invaded range of Portugal both acacia species were able to establish novel mutualistic interactions, predominantly with generalist pollinators. For each of the two studied sites, only two other co-occurring native plant species presented partially overlapping phenologies. We observed significant differences in pollinator richness and visitation rates among native and non-native plant species, although the study of b diversity indicated that only the native plant Lithodora fruticosa presented a differentiated set of pollinator species. Acacias experienced a large number of visits by numerous pollinator species, but massive acacia flowering resulted in flower visitation rates frequently lower than those of the native co-flowering species. We conclude that the establishment of mutualisms in Portugal likely contributes to the effective and profuse production of acacia seeds in Portugal. Despite the massive flowering of A. dealbata and A. longifolia, native plant species attained similar or higher visitation rates than acacias.
