Abstract

Meiofauna communities were analysed from samples collected at four stations on the Kenyan continental shelf (Shimoni, Kwale, Mombasa and Kilifi) during the maiden cruise of the RV Mtafiti, 12–21 December 2015. Nematodes were identified to genus level, and their distribution and composition were mainly influenced by grain size distribution, a finding similar to studies in other areas with a similar grain size distribution (iso-communities). The southern stations (Shimoni and Kwale) had coarser sediments than the northern stations (Mombasa and Kilifi). The family Chromadoridae was dominant at Shimoni, while Cyatholaimidae dominated at Kwale. Mombasa was dominated by Chromadoridae, Cyatholaimidae and Oxystominidae, and Kilifi by Xyalidae. The dominant genera portrayed a trend similar to that observed in the families, in that the dominant genera were members of the dominant families. Spilophorella was dominant at Shimoni, and Paracanthonchus, Paracyatholaimus, Desmodora, Microlaimus and Draconema were dominant at Kwale and Mombasa. Microlaimus, Daptonema and Terschellingia represented the highest abundances at Kilifi. All stations were dominated by epistratum feeders. Selective deposit feeders were the second-most-dominant feeding guild at Mombasa and Kwale, whereas non-selective feeders had the second-highest abundance at Kilifi. The diversity index was highest at Mombasa and lowest at Shimoni, whereas dominance was highest at Shimoni and lowest at Mombasa.

Abstract

The biodiversity of marine and coastal habitats is experiencing unprecedented change. While there are well-known drivers of these changes, such as overexploitation, climate change and pollution, there are also relatively unknown emerging issues that are poorly understood or recognized that have potentially positive or negative impacts on marine and coastal ecosystems. In this inaugural Marine and Coastal Horizon Scan, we brought together 30 scientists, policymakers and practitioners with transdisciplinary expertise in marine and coastal systems to identify new issues that are likely to have a significant impact on the functioning and conservation of marine and coastal biodiversity over the next 5-10 years. Based on a modified Delphi voting process, the final 15 issues presented were distilled from a list of 75 submitted by participants at the start of the process. These issues are grouped into three categories: ecosystem impacts, for example the impact of wildfires and the effect of poleward migration on equatorial biodiversity; resource exploitation, including an increase in the trade of fish swim bladders and increased exploitation of marine collagens; and new technologies, such as soft robotics and new biodegradable products. Our early identification of these issues and their potential impacts on marine and coastal biodiversity will support scientists, conservationists, resource managers and policymakers to address the challenges facing marine ecosystems., (© 2022.
