The north-west marine bioregion of Australia, which includes the waters adjacent to the Kimberley and Ningaloo coasts, is influenced by both the Indian and Pacific oceans and has high tropical biodiversity, some of which is conserved in a suite of Marine Protected Areas. In the present study, the epipelagic euphausiid assemblages of this bioregion were investigated and related to the physical and biogeochemical properties of the water column, as well as food availability. Twenty-five euphausiid species were identified, including three new records for Australian waters. Pseudeuphausia latifrons was the most abundant species, dominating the shelf waters across both study areas. Stylocheiron carinatum replaced P. latifrons in the deeper waters where species richness was greater. Off Ningaloo, there were higher concentrations of euphausiids, and this may be linked to the bathymetry, the narrowness of the shelf and the resultant effects of these features on oceanography and biogeochemistry. Assemblages were primarily structured by depth, but mean seawater density, dissolved oxygen, fluorescence and mesozooplankton abundance also significantly explained some of the variation in euphausiid assemblages. The present study has confirmed that the physical and biogeochemical properties of the water column and food availability are recurrent factors affecting euphausiid assemblage variation in the eastern Indian Ocean.

New records and possible range extensions are reported on 45 bird species (ca 25% of the 167 species recorded during surveys) in the Bophirima district of the North-West Province, South Africa. The findings were compared with data in The Atlas of Southern African Birds. The main reasons for these new records may be ascribed to the low number of visits during the atlas project, higher precipitation during the time of our observations versus that of the atlas project, and possibly an increased suitability of the area for some bird species due to human habitation. These new records also provide additional information that may be useful in conservation planning, especially in arid areas. Heuningvlei Pan in particular, should be considered for additional conservation measures.

SynopsisFrom a faunistic survey in Scottish waters, concentrated mainly in the sea lochs of the north-west coast and in the deep water in the North Sea off the east coast, thirty-two species of polychætes are listed which have not previously been recorded from these areas. Seven of the species are new records for British coastal waters or for the North Sea.

With the objective of assessing the farmers’ situation regarding the use of the ICT and their relations with the electronic government, a case study consisting in the realization of 34 face-to-face surveys was conducted between February and March 2020 in dairy farms in the region of Galicia (Spain). The sample was selected according to one of the most important online journals in the farming sector at a national level. From the census, we chose those farms considered most representative taking into account the main criteria: the level of PAC (Common Agrarian Politics) subsidies and milk production (litres/cow and year). The results show that the majority of the farmers used the internet, but on many an occasion, they were discontented in relation to the poor connection quality in their farms. In regard to the use of the electronic government for procedures related to their farms, many of them were able to perform them through the government website; however, there were procedures which the users defined as “complex” and which had to be outsourced to authorised entities. The results also show that the farmers do want to employ the e-government, mainly because of the time and cost saving; however, the current web pages do not meet the users’ expectations. Finally, this situation, applied to a region placed among the 10 most productive regions of milk, is comparable to what happens in other regions.

Russia is now on the 4th place in terms of total actual catch in the world. Despite the fact that the main part of the Russian catch is in the Russian exclusive economic zone (EEZ), many companies have started to look for new fishing areas and targets beyond the waters of national jurisdiction (ABNJ). Our analysis shows that the largest share of fish harvested by Russia outside its EEZ is in NEAFC areas, the North West Pacific area is quite promising as well. Preliminary analysis showed some signs of insufficiently controlled activity of the Russian fleet in the areas of ABNJ. This requires additional efforts to improve the monitoring system, especially in "restricted areas”, marine protected areas (MPAs) and areas of reproduction.

Background: Informal women entrepreneurs in the rural villages of North-West strive to progress from poverty to prosperity. There is a growing appreciation that the conditions that support women’s ability to start and grow ventures may be different from those that help men and therefore there is a need to examine the motivational factors affecting women’s enterprise development.Aim: The study aimed to identify the motivational factors of women in the Mahikeng area to start informal enterprises, the barriers they experience and their developmental business needs.Setting: The study focussed on informal women entrepreneurs in the rural villages of Mahikeng in the North-West province.Methods: In total, 80 face-to-face questionnaires were completed with women entrepreneurs. A principal component analysis of 15 items of the total questionnaire was performed on the data to determine which items could be reduced and transformed into new components.Results: ‘Destitute conditions’, ‘Entrepreneurial Spirit’ and ‘Passion for Product’ emerged as the three underlying motivational factors. The component ‘Destitute conditions’ was ranked as the most important reason for starting an informal business. The need to transcend impoverished conditions (a push factor) and the need for self-determination (a pull factor) were almost equally strong amongst the 80 participants. ‘Lack of financial and business skills’ was ranked as the biggest obstacle to keeping the business running. Ninety-one per cent of the women entrepreneurs reported that they had never received any training from the government or the private sector.Conclusions: Access to basic infrastructure, training, funding and business networks will enable self-efficacy behaviour of women entrepreneurs in the Mahikeng district to move beyond poverty. Recommendations included the establishment of a regional database of informal women entrepreneurs, the improvement of basic facilities and infrastructure and access to microloans as well as training by the formal sector.

In 1996 a sponge was found in a well studied area in the Ria of Etel, Brittany, France, that had never been recorded there before. This sponge was later described as a new species and genus,Celtodoryx girardaeby Perezet al.(2006), who concluded that it is probably an invasive species. Over several yearsC. girardaewas found to occur successively in the Gulf of Morbihan, France, and Oosterschelde estuary, Netherlands. This sponge is characterized by an extensive spatial broading and therewith it rates today among the dominant benthic megafauna in the shallow waters of the Gulf of Morbihan and Dutch inshore waters. During our recent survey of the Chinese Yellow Sea sponge fauna, we found an abundant species with close morphological similarities toC. girardae. Further taxonomic studies have revealed that both the Chinese and European sponges are in fact conspecific withCornulum ciocalyptoidesdescribed by Burton (1935) from Posiet Bay, Sea of Japan and later recorded from other localities of the North West Pacific (e.g. Koltun, 1971; Sim & Byeon, 1989). In this paper we transfer the species of Burton fromCornulumtoCeltodoryxand consequently it becomes the senior synonym ofC. girardae. Furthermore, we conclude thatCeltodoryx ciocalyptoideswas introduced to the North East Atlantic from the North West Pacific with aquaculture of the Pacific oysterCrassostrea gigasas the probable vector. This is probably the first case recorded so far of a sponge species being transferred from one ocean to another by human activity.

Surveys with binoculars at two different times of day and in various months of the year, along with camera trap studies of diel activity patterns, were used to inform an appropriate period to count mountain hares ( Lepus timidus) on managed red grouse (Lagopus lagopus ) moorland of the Lammermuir Hills, south-east Scotland. Factors affecting the numbers of hares counted were time relative to sunrise, the presence of winter coat colour and reproductive behaviour in spring. Counts of hares in March and April starting one hour before dawn were used as an index of population size of the mountain hare over three years of observations on three hill-tops, with densities of 23-33 hares km-2. The number of hares seen was stable or rose slightly over the three years despite a partial cull on one of the hills. In support of suitability of the timing of surveys used, camera trap studies revealed that the period around dawn in March and April was associated with high levels of hare activity.
