“…As a consequence, shelf waters in the region can be characterised by three major zones parallel to the coast (e.g. Lowe-McConnell 1962, Willems et al 2015. The brown nearshore waters have a high turbidity and low salinity due to suspension of the muddy deposits and freshwater input of both the Amazon and local rivers.…”

Bird observations were collected from various types of survey vessels in Suriname's territorial waters between 2013 and 2015. Dedicated, effort-related surveys were carried out from geophysical seismic survey vessels within an area located 80-110 km offshore (in 2013) and 165-290 km (in 2015). Opportunistic observations were recorded during fisheries surveys on a shrimp trawler operating along the 30 m depth contour, approximately 40-60 km offshore (in 2014). In total, 10 bird (sub-)species were observed during these surveys that previously were not recorded for Suriname, including Manx Shearwater Puffinus puffinus, Ruff Calidris pugnax, South Polar Skua Stercorarius maccormicki, Long-tailed Jaeger Stercorarius longicaudus, Sandwich Tern Thalasseus sandvicensis (ssp. acuflavidus), Roseate Tern Sterna dougallii, Bridled Tern Onychoprion anaethetus, Black Noddy Anous minutus, Scarlet Tanager Piranga olivacea and Black-and-white Warbler Mniotilta varia. In addition, Lesser Black-backed Gull Larus fuscus and Bulwer's Petrel Bulweria bulwerii were photographed for the first time in Suriname. A Sooty Shearwater Ardenna grisea was recorded just outside the Exclusive Economic Zone (EEZ), and therefore does not count as a new country record. This paper contributes to a better understanding of the avifauna frequenting the waters off Suriname, which historically has been poorly studied. Most of the species reported here are migratory. The timing of our sightings therefore also helps in a better understanding of their at-sea distribution and migration patterns.

“…This area receives an average of 2-3 m of annual rainfall, of which most falls in the wet seasons between December-February and April-July. Despite high precipitation, the rivers in Suriname have relatively low discharges ($150 km 3 /yr) and suspended loads (1-130 mg/L), especially compared to the total alongshore sediment transport and the mud supply originating from the Amazon River (Willems et al, 2015). Nearshore brown waters, between 0 and 20 km offshore, have a high turbidity that can be associated with the suspension of muddy sediments or the presence of mudbanks (Figure 1).…”

For the development of climate-resilient coastal management strategies, which focus on challenges in the decades to come, it is critical to incorporate spatial and temporal variability of coastline changes. This is particularly true for the mud-dominated coastline of Suriname, part of the Guianas, where migrating subtidal mudbanks cause a cyclic instability of erosion and accretion of the coast that can be directly related to interbank and bank phases. The coastline hosts extensive mangrove forests, providing valuable ecosystem services to local communities. Recent studies on mudbank dynamics in Suriname predominantly focused on large-scale trends without accounting for local variability, or on local changes considering the dynamics of a single mudbank over relatively short time scales. Here we use a remote sensing approach, with sufficient spatial and temporal resolution and full spatial and temporal coverage, to quantify the influence of mudbank migration on spatiotemporal coastline dynamics along the entire coast of Suriname. We show that migration of six to eight subtidal mudbanks in front of the Suriname coast has a strong imprint on local coastline dynamics between 1986 and 2020, with an average 32 m/yr accretion during mudbank presence and 4 m/yr retreat of the coastline during mudbank absence. Yet, coastal erosion can still occur when mudbanks are present and coastal aggregation may happen in the absence of mudbanks, exemplifying local variability and thus suggesting the importance of other drivers of coastline changes.The novel remote sensing workflow allowed us to analyse local spatial and temporal variations in the magnitude and timing of expanding and retreating trajectories. Our results demonstrate that it is essential that all coastal behaviours, including changes that cannot be explained by the migration of mudbanks, are included in multi-decadal management frameworks that try to explain current variability, and predict future coastline changes in Suriname.

“…The Atlantic seabob shrimp, Xiphopenaeus kroyeri (Heller, 1862) (Dendrobranchiata: Penaeoidea: Penaeidae), inhabits sandy and muddy bottoms in the subtropical and tropical coasts of the Western Atlantic (Holthuis, 1980). Xiphopenaeus kroyeri can be found in high densities in the intertidal zone to depths up to 30 m (Willems et al, 2015).…”

The Atlantic seabob shrimp, Xiphopenaeus kroyeri (Heller, 1862) (Penaeidae), is commonly found on western Atlantic coasts and of high commercial importance in Brazil, Suriname, and Guyana. Current genetic resources on X. kroyeri are scarce and no genomic studies are available. This study reports the complete mitochondrial genome of X. kroyeri. Using the pipeline NOVOPlasty, we assembled and circularized the complete mitochondrial genome of X. kroyeri with an average coverage of 68x per nucleotide. The AT-rich mitochondrial genome of X. kroyeri is 15,999 bp in length and comprised of 13 protein-coding genes (PCGs), 2 ribosomal RNA genes, and 22 transfer RNA genes. A single 1,030 bp long intergenic space is assumed to be the D-loop/Control region (CR). Selective pressure analysis indicated that the PCGs were under purifying selection. The KA/KS ratios observed for cox1, cox2, atp6, cox3, and cob were found to be much lower than the ratios observed in the other PCGs, suggesting strong purifying selection upon the former genes. The secondary structures of the tRNA genes exhibited a standard ‘cloverleaf’ structure, with the exception of trnS1. A maximum likelihood phylogenetic analysis based on all PCGs indicated that X. kroyeri is more closely related to penaeids (Penaeidae) belonging to the genera TrachypenaeusAlcock, 1901, PenaeopsisSpence Bate, 1881, and MierspenaeopsisK. Sakai & Shinomiya, 2011. This study contributes new genomic resources for this commercially important species which may aid in distinguishing cryptic species and elucidating phylogeographic patterns.
