Shallow-water Holothuroidea (Echinodermata) from Kenya and Pemba Island (Tanzania)
- A total of 225 specimens - representing three orders, four families, 12 genera, 44 species and one variety - collected in the shallow-waters of Kenya and Pemba Island (Tanzania) - are investigated. Bohadschia cousteaui, B. similis, Holothuria (Metriatyla) albiventer; Pearsonothuria graeffei, Thelenota anax, Euapta godeffioyi, Opheodesoma grisea, 0. spectabilis and Synaptula recta are new records for Kenya and from Pemba Island (Tanzania). H. (M) timana is a new record for the western Indian Ocean. Diagnostic characters and descriptions (including some brief notes on the ecology) are given for most species. Identification keys up to the species level are also included. The results are compared to the shallow-water holothuroid biodiversity of the western Indian Ocean. This study stresses the richness of the holothuroid biodiversity of Kenya and Pemba Island. The holothuroid fauna of Kenya (with Pemba Island) is now represented by 48 species.

Conservation of aspidochirotid holothurians in the littoral waters of Kenya.
- Aspidochirotid sea cucumbers (Echinodermata: Holothuroidea) are heavily fished in the littoral waters of Kenya, and stocks have plummeted. In order to conserve and manage these natural resources, appropriate conservation and management plans must to be developed. This can only occur if high quality research on different levels is done. This paper discusses five layers of understanding that should be achieved before holothurian conservation in East Africa can be effective.

Revealing patterns of nocturnal migration using the European weather radar network
- Nocturnal avian migration flyways remain an elusive concept, as we have largely lacked methods to map their full extent. We used the network of European weather radars to investigate nocturnal bird movements at the scale of the European flyway. We mapped the main migration directions and showed the intensity of movement across part of Europe by extracting biological information from 70 weather radar stations from northern Scandinavia to Portugal, during the autumn migration season of 2016. On average, over the 20 nights and all sites, 389 birds passed per 1 km transect per hour. The night with highest migration intensity showed an average of 1621 birds km–1 h–1 passing the radar stations, but there was considerable geographical and temporal variation in migration intensity. The highest intensity of migration was seen in central France. The overall migration directions showed strong southwest components. Migration dynamics were strongly related to synoptic wind conditions. A wind‐related mass migration event occurred immediately after a change in wind conditions, but quickly diminished even when supporting winds continued to prevail. This first continental‐scale study using the European network of weather radars demonstrates the wealth of information available and its potential for investigating large‐scale bird movements, with consequences for ecosystem function, nutrient transfer, human and livestock health, and civil and military aviation.

National survey among anglers in Belgium: towards the first awareness raising campaign on biosecurity
- Aquatic ecosystems are one of the most impacted ecosystems by biological invasions. Potential invasion pressure of the species already present in freshwater systems in Belgium is particularly high. Since eradication or long-term management of invasive species in these systems is challenging if not impossible, preventing new introductions and spread of species already present is crucial. Therefore, it is paramount to convince water users to adopt biosecurity measures to prevent the unintentional transportation of propagules of IAS while performing their hobby or professional activity. To develop a biosecurity campaign for Belgian anglers, a national online survey for anglers was organized during the spring of 2023. The aim of this survey was manyfold: gain a better understanding of angler information channels, angler mobility and angling frequency, assess current routines of equipment maintenance and bait disposal and also assess anglers’ awareness and perception on the issue of biological invasions. Results indicated that there is a real risk that anglers can introduce IAS in uninvaded systems either by unintentionally moving organisms around by changing locations during one trip (one fourth of anglers) or by bringing them back from abroad (45% of anglers). This is especially true since only 7% of anglers adhere to the full check-clean-dry routine after each trip. Additionally, sometimes anglers indicated to move undesired species to another location. However, respondents’ perception on IAS was rather negative, with anglers citing them amongst the five main threats for angling indicating they could be concerned allies in the fight against IAS. The results of the survey will inform our future work with the angling community in Belgium to design adequate messages, efficiently reach the target audience and assess if the campaign had an influence on angler habits and awareness.
