“…Invasive species are increasingly viewed as a significant component of global change and one of the major drivers of current biodiversity loss (Didham et al ., ). In this context, nativeness has become the sine qua non invoked by many management policies, plans and actions to justify intervening on prevailing ecosystem processes (Chew & Hamilton, ). Although the distribution of alien species urgently needs to be documented for risk assessments, such information remains scarce in some geographical areas and taxonomic groups (Vilà et al ., ).…”

Essl and colleagues documented worldwide invasion patterns in bryophytes, which so far have been neglected in invasion biology. In the absence of historical evidence, Essl and colleagues used criteria such as anomalous geographical distribution, preference for disturbed habitats, and indirect associations with some means of human transport as criteria to identify aliens. Because bryophytes exhibit high long‐distance dispersal capabilities, disjunct distribution patterns are, however, the rule rather than the exception in the group. In our opinion, none of the previously proposed criteria to characterize aliens can be satisfactorily applied to groups like bryophytes, for which historical and fossil records are extremely scarce. We suggest that, in order to validate the conclusions of Essl and colleagues, further taxonomic and phylogeographical studies are needed. This is especially true for island floras, for which recent critical taxonomic work and updated checklists, which compose the primary source of information for biodiversity, are largely missing.

“…The native/non-native dichotomy Though most famously articulated by Elton (1958), the native/ non-native distinction predates his oft-cited work. Chew and Hamilton (2011) trace the separation of 'native' and 'alien' species to Hewitt (H.C.) Watson in the early 19th century. Watson did not extend his definition into value judgments or conservation concerns; it took until the early twentieth century with Elton and his colleagues for the dichotomy to fully develop.…”

“…The proposal would have removed key sources of shade in the park and replaced them with native species known to potentially cause hayfever and allergic reactions (Trigger and Head, 2010). Chew and Hamilton (2011) offer an interesting example of origin-based decision-making in an occurrence in Britain. Pool frogs, Pelophylax lessonae, are a common species across all of Europe thought to be descendent from a single Central European animal introduced to Britain in the 1800s.…”

Finding a middle-ground: The native/non-native debate

a b s t r a c tThroughout the history of invasion biology, there has been long-standing and sometimes fierce debate on the perception and management of non-native species. Some argue that non-native species are universally undesirable for their unpredictability and their ability to at times dramatically disrupt native species and systems. Others argue for an approach that weighs a species' impact and role in a system before determining its desirability, irrespective of its identity. We suggest a middle-ground approach, one that does add extra caution about the desirability of non-native species relative to native species, but also bases perception and management decisions on the population stage of the non-native species and in relation to a wider range of conservation goals. In initial stages of introduction and establishment, we argue that a cautious approach is most prudent, one assuming the potential dangers of the new species in systems. In later stages of established populations, we argue that impact assessments will provide the soundest and more efficient management information, with origin and other available data included as part of the subsequent decision-making process. We explore and expand on these suggestions, and hope that the perspective presented respectfully contributes to finding a common ground in a long and polarized debate.

“…Thus, from a strictly continental or world-ocean perspective, it may be easy to relativize or even dismiss nativeness [9,10]. As a consequence, the role of any insularity syndrome has been also dismissed as a minor contribution to extinction risk and species endangerments [1,11,12]. This may sound counterintuitive to researchers acquainted with the depauperate and disarmed nature of insular ecosystems, yet it stems from a lack of convincing documentation.…”

Extinction Resilience of Island Species: An Amphibian Case and a Predictive Model

Extreme overall divergence and high extinction rates are typical of insular endemics. Thus, detecting and understanding nativeness is critical on islands. Resilience to extinction is explored through a mechanistic approach focusing on midwife toads (Anura: Alytidae: Alytinae), an ancient lineage that includes continental and insular species. All alytines need urgent conservation action, including control of emerging diseases and spatially explicit reserve design aimed at ensuring ecosystem health and connectivity. The only extant insular alytine is additionally affected by an introduced continental predator. This alien species acts as a driver of the prey's near-extinction and has not elicited any evolutionary response. Both IUCN criteria and EDGE scores show that alytines are top conservation priorities. However, there is a need for also considering phenotypic and ecological uniqueness in the assessment of conservation status and urgency. The reason is that phenotypes render ecosystems functional and insular ones uniquely so. In contrast, phylogenetic relatedness is just a constraint upon, not a motor of, evolutionary novelty. Insular species are indeed particularly susceptible, but can be similarly endangered as continental ones. This paradox may be solved by recognizing the insularity syndrome in any isolated or nearly-insular ecosystem, as a function of evolutionary and dispersal potentials. This predictive model may be useful for island biogeography, invasion biology and conservation planning.
