The risk of aquatic invasive species (AIS) introductions in the Arctic is expected to increase with ongoing trends of greater shipping activity, resource exploitation, and climate warming in the region. We identified a suite of AIS (benthos, zooplankton and macroalgae) with the greatest likelihood of introduction and impact in the Canadian Arctic using the Canadian Marine Invasive Screening Tool. The top sixteen riskiest species (mainly benthic) were then modelled to predict the potential spatial distributions (habitat modelling using Maximum Entropy) at an Arctic scale. Modelling was conducted under present environmental conditions and under two future global warming scenarios (2050 and 2100). Results show that hotspots or regions where suitable habitat is more densely accumulated for modelled AIS are in the Hudson Complex, Chukchi / Eastern Bering Sea, and Barents / White Sea. Most taxonomic groups showed a trend for a positive poleward shift in the future, increasing from the present time to the end of the century. This approach will aid in the identification of present and future high-risk areas for AIS in response to global warming.

The article explores the possibilities and problems of the process of harmonization of the HR audit in the field of international practice, taking into account the specifics of the market environment of Ukraine. The views of different authors on the problem of HR auditing were investigated. The idea was justified that the harmonization of accounting and financial reporting of economic entities is closely linked with the globalization of economic processes and the economy as a whole on a global scale, the processes of informatisation and digitalization of society, the same as for HR processes. During considering the concept of “HR audit” it should not be forgetting about the legislative component — HR audit is aimed, inter alia, at identifying violations with the law for timely management of weaknesses in the policy of the enterprise in the field of labor. Categorization of observations by impact of importance (high-risk, medium-risk, low-risk — categorization) was investigated; examples for high-risk observations (on the example of: workforce planning, service contract modalities) and medium-risk (on the example of: recruitment process governance, alignment of strategy and work plans, HR functional capacity in Country Offices, talent acquisition in Cos, recruitment processes in Cos, employee on-boarding, training and separation, national non-staff salary scales and pay adjustments, staffing and structure review exercises, social security transfers to service contracts, automation, information and data management, oversight of HR functions in Cos) are given in consideration with agreed actions of HRM and auditor. The ratings (satisfactory, partially satisfactory or unsatisfactory) of an HR audit that are part of the system of evaluating the adequacy of company’s audit risk management, control and governance processes were investigated. The point that the human resource auditing is something that many companies do annually, just as they audit their financial information (despite of their field of activity) is overlined in the article. The harmonization of the HR audit in the field of international practice is a process of unification of methods and principles of auditing in the form of standards is observed.

Aquatic Invasive species (AIS) are a growing driver of change across marine and freshwater ecosystems but spatially-explicit information is seldom available for supporting management actions and decision making. Here we conceived and tested a new participatory method to map the distribution of three invasive species (Callinectes sapidus, Procambarus clarkii and Oreochromis niloticus) in the coastal lagoon of Lesina (Italy). Local fishers were asked to draw the distribution of each species on pre-printed maps, indicating districts of the lagoon characterized by different abundance levels. Then, maps were converted to a lattice grid and a Bayesian hierarchical Generalized Additive Modeling was adopted to model species distribution in the lagoon, calculating the coefficient of variation for model fitted values to map fishers agreement about the distribution of each species.The spatial gradient in the abundance of the three species in the lagoon aligned with their ecological requirements. C. sapidus was abundant throughout the whole lagoon, peaking in correspondence of saltmarsh vegetation, while P. clarkii and O. niloticus, were much less abundant and remained distributed near to freshwater inputs. Experts agreed about the spatial distribution of C. sapidus in the lagoon, with a median coefficient of variation in model fitted values of 3.9%. On the other hand, the coefficient of variation was higher for P.clarkii (19.9%) O. niloticus (18.4%), indicating a higher level of uncertainty about their estimated distribution.With this example, we provided new metrics to evaluate the quality of LEK-based participatory mapping in terms of agreement and consistency among experts. The resulting information provides new insights for spatially informed management across aquatic realms in relation to the increasing ecological and socio-economical pressures posed by biological invaders.
