The Biogeography of Invasive Plants – Projecting Range Shifts with Climate Change

نویسنده

چکیده

Correlative models between species occurrences and climate (here referred to as ‘habitat suitability models’) have become increasingly popular for forecasting risk from invasive plants under current and future climate scenarios. Th ese models have the potential to inform management and monitoring eff orts by prioritizing landscapes considered at highest risk under a changing climate. However, a wide range of choices regarding climatic predictor variables, model ling approaches and even dis tributional data sets infl uences the resulting projections. Th e eff ects of these choices are seldom defi ned explicitly, which reduces their utility for scientists and managers alike. Th is chapter reviews common practices of habitat suitability modelling as they apply to invasive plants. Th e chapter also reviews major fi ndings of recent projections of range shifts in invasive plants. In both cases, the aim is to explore how diff erent choices of predictors, models and input data can infl uence conclusions in a habitat suitability modelling framework and develop recommendations for best practices.

Modeling the effect of climate change to the potential invasion range of Piper aduncum Linnaeus

The potential effect of invasive plant species on biodiversity is one of most important subject of inquiry at present. In many parts of the world, the alarming spread of these plants has been documented. Knowing that climate exerts a dominant control over the distribution of plant species, predictions can therefore be made to determine which areas the species would likely spread under a climate...

The effects of climate change on the distribution of an invasive fish in Iran: Gambusia holbrooki (Girard, 1859)

Today, invasive species are considered as one of the major threats to biodiversity and ecosystem functions. The suitable habitats of these species are expected to be expanded under the effects of future climate change hence it is likely to threaten the existence of native species. Consequently, identifying the current and potential distribution range of invasive species is essential for managem...

Use and Misuse of the IUCN Red List Criteria in Projecting Climate Change Impacts on Biodiversity

Recent attempts at projecting climate change impacts on biodiversity have used the IUCN Red List Criteria to obtain estimates of extinction rates based on projected range shifts. In these studies, the Criteria are often misapplied, potentially introducing substantial bias and uncertainty. These misapplications include arbitrary changes to temporal and spatial scales; confusion of the spatial va...

Climate warming affects biological invasions by shifting interactions of plants and herbivores.

Plants and herbivorous insects can each be dramatically affected by temperature. Climate warming may impact plant invasion success directly but also indirectly through changes in their natural enemies. To date, however, there are no tests of how climate warming shifts the interactions among invasive plants and their natural enemies to affect invasion success. Field surveys covering the full lat...

Priority threat management of invasive animals to protect biodiversity under climate change.

Climate change is a major threat to global biodiversity, and its impacts can act synergistically to heighten the severity of other threats. Most research on projecting species range shifts under climate change has not been translated to informing priority management strategies on the ground. We develop a prioritization framework to assess strategies for managing threats to biodiversity under cl...
