Species moved by human activities beyond the limits of their native geographic ranges into areas in which they do not naturally occur (termed aliens) can cause a broad range significant changes to recipient ecosystems; however, impacts vary greatly across species and ecosystems are introduced. There is therefore critical need for standardised method evaluate, compare, eventually predict magnitudes these different impacts. Here, we propose straightforward system classifying alien according...
Human factors/ergonomics (HFE) has great potential to contribute the design of all kinds systems with people (work systems, product/service systems), but faces challenges in readiness its market and supply high-quality applications. HFE a unique combination three fundamental characteristics: (1) it takes approach (2) is driven (3) focuses on two closely related outcomes: performance well-being. In order future system design, must demonstrate value more successfully main stakeholders design....
An experimental program of research was carried out to assess the potential health and safety effects participating in virtual environments (VEs) via head-mounted displays (HMDs). This paper presents results obtained from nine experiments examining experienced during after participation a variety VR systems, VE designs, task requirements, for total participant sample 148 individuals. A combination methods including self-report scales, performance measures, physiological indicators,...
ABSTRACT A prime aim of invasion biology is to predict which species will become invasive, but retrospective analyses have so far failed develop robust generalizations. This because many biological, environmental, and anthropogenic factors interact determine the distribution invasive species. However, in this paper we also argue that invasiveness been flawed by not considering several fundamental issues: (1) range size an depends on how much time it has had spread (its residence time); (2)...
Although invasive alien species (IAS) are a major threat to biodiversity, human health, and economy, our understanding of the factors controlling their distribution abundance is limited. Here, we determine how environmental factors, land use, life-history traits invaders, residence time, origin, usage interact shape spatial pattern plant in South Africa. Relationships between extrinsic intrinsic attributes were investigated using RLQ analysis, multivariate method for relating...
Abstract Many alien taxa are known to cause socio‐economic impacts by affecting the different constituents of human well‐being (security; material and non‐material assets; health; social, spiritual cultural relations; freedom choice action). Attempts quantify in monetary terms unlikely provide a useful basis for evaluating comparing because they notoriously difficult measure important aspects ignored. Here, we propose novel standardised method classifying magnitude their on well‐being, based...
Abstract Aim Australian acacias (1012 recognized species native to Australia, which were previously grouped in Acacia subgenus Phyllodineae ) have been moved extensively around the world by humans over past 250 years. This has created opportunity explore how evolutionary, ecological, historical and sociological factors interact affect distribution, usage, invasiveness perceptions of a globally important group plants. editorial provides background for 20 papers this special issue Diversity...
Managing biological invasions relies on good global coverage of species distributions. Accurate information alien distributions, obtained from international policy and cross-border co-operation, is required to evaluate trans-boundary trading partnership risks. However, a standardized approach for systematically monitoring tracking still lacking. This Perspective presents vision observation invasions. We show how the architecture provided by minimum set Essential Variables, collaboration data...
Abstract Recently, Blackburn et al . (2014) developed a simple, objective and transparent method for classifying alien taxa in terms of the magnitude their detrimental environmental impacts recipient areas. Here, we present comprehensive framework guidelines implementing this method, which term Environmental Impact Classification Alien Taxa, or EICAT. We detail criteria applying EICAT scheme consistent comparable fashion, prescribe supporting information that should be supplied along with...
Substantial progress has been made in understanding how pathways underlie and mediate biological invasions. However, key features of their role invasions remain poorly understood, available knowledge is widely scattered, major frontiers research management are insufficiently characterized. We review the state art, highlight recent advances, identify pitfalls constraints, discuss challenges four broad fields pathway management: classification, application information, response, impact....
Abstract Aim We develop a framework for quantifying invasions based on lagged trends in (‘invasion debt’) with the aim of identifying appropriate metrics to quantify delayed responses at different invasion stages – from introduction when environmental impacts occur. Location World‐wide; detailed case study South Africa. Methods define four components debt: number species not yet introduced but likely be future given current levels introduction/propagule pressure; establishment species;...
There is a long history of species being moved around the world by humans. These introduced can provide substantial benefits, but they also have undesirable consequences. We explore importance human activities on processes dissemination and potential invasions using grass subfamily Bambusoideae ("bamboos"), group that contains taxa are widely utilised often perceived as weedy. (1) compiled an inventory bamboo their current distributions; (2) determined which been become invasive outside...
Human activities such as the transport of species to new regions and modifications environment are increasingly reshaping distribution biota. Accordingly, developing robust, repeatable, consistent definitions alien that serve scientific policy purposes has become prime importance. We provide a set classification criteria widely applicable across taxa realms offer guidance on their use in practice. The focus (a) acknowledging role assessment uncertainty, (b) incorporating time since...
